mother nature is an exquisite and complex life-system. it's charm appears in the trees, stream, soil, insects, moss and fungus, all the things on the earth in different shapes, which are interdependent. when you get close to nature, please remember, each tree, stone and species of animals here has lived harmoniously for hundreds, thousands or even millions of years. when we pass away, they will continue to live. they are the real masters, while we are just the passer-by. however, the conduct we unconsciously do, such as picking, lumbering, tramping and abusing can probably destroy the balance of their life. therefore, we must reduce our bad influence as much as possible. while you are enjoying the nature, do not forget please, the beauty of the lives also needs to be concerned with and to be protected.
each life on the earth has a long and touching evolutionary story. from the origin, the lives of the human being are equal to those of others; they both are the composing parts of mother nature. nevertheless, for some inexplicable reasons, the human becomes the spirits of all creatures. of course, it is the result of the evolution, but still we should be grateful to all our companions in nature for the opportunity they offer.
in spite of this, humans cannot live without earth. they live on the earth, drink the sweet water, and enjoy the sunshine, the air, the sky, the fruit; the grains utilize the energy and so on. in a word, the human being cannot live without nature, and mother nature makes us grow stronger.
i do not like the word "pet", but preferring the word "animal" instead. i have been loving animal since i was just a little boy. when thinking of the "pet fashion", i always feel much annoyed. for the animals will be given a shackle and lose their liberty if they become someone's pets. their natural attribution can be deprived, too.
up to now, relying on their scientific power, the human have opened up too much and over developed nature, in order to fill up their growing appetites of wealth. they destroy the balance of nature, however, they don't realize, their own development and existence will be threatened. therefore, our sights should be focused on nature and we should try to develop the concept of "keeping human and nature in unity".
we should lay emphasis on our education with consider cultural and natural emotion. to use the vivid example to wake up the conscience in people's hearts.
to love nature is to love our mankind. as the new generation who enter the new century, we should make efforts to love and respect nature, to treat it well and protect it. at last, we have the night to enjoy it.

President pitzer Mr. Vice President, Governor, Congressman Thomas, Senator Wiley, and Congressman Miller, Mr. Webb, Mr. Bell, scientists, distinguished guests, and ladies and gentlemen:
I appreciate your president having made me an honorary visiting professor, and I will assure you that my first lecture will be very brief.
I am delighted to be here and I'm particularly delighted to be here on this occasion.
We meet at a college noted for knowledge, in a city noted for progress, in a state noted for strength, and we stand in need of all three, for we meet in an hour of change and challenge, in a decade of hope and fear, in an age of both knowledge and ignorance. The greater our knowledge increases, the greater our ignorance unfolds.
Despite the striking fact that most of the scientists that the world has ever known are alive and working today, despite the fact that this Nation's own scientific manpower is doubling every 12 years in a rate of growth more than three times that of our population as a whole, despite that, the vast stretches of the unknown and the unanswered and the unfinished still far outstrip our collective comprehension.
No man can fully grasp how far and how fast we have come, but condense, if you will, the 50,000 years of man's recorded history in a time span of but a half-century. Stated in these terms, we know very little about the first 40 years, except at the end of them advanced man had learned to use the skins of animals to cover them. Then about 10 years ago, under this standard, man emerged from his caves to construct other kinds of shelter. Only five years ago man learned to write and use a cart with wheels. Christianity began less than two years ago. The printing press came this year, and then less than two months ago, during this whole 50-year span of human history, the steam engine provided a new source of power. Newton explored the meaning of gravity. Last month electric lights and telephones and automobiles and airplanes became available. Only last week did we develop penicillin and television and nuclear power, and now if America's new spacecraft succeeds in reaching Venus, we will have literally reached the stars before midnight tonight.
This is a breathtaking pace, and such a pace cannot help but create new ills as it dispels old, new ignorance, new problems, new dangers. Surely the opening vistas of space promise high costs and hardships, as well as high reward.
So it is not surprising that some would have us stay where we are a little longer to rest, to wait. But this city of Houston, this state of Texas, this country of the United States was not built by those who waited and rested and wished to look behind them. This country was conquered by those who moved forward--and so will space.
William Bradford, speaking in 1630 of the founding of the Plymouth Bay Colony, said that all great and honorable actions are accompanied with great difficulties, and both must be enterprised and overcome with answerable courage.
If this capsule history of our progress teaches us anything, it is that man, in his quest for knowledge and progress, is determined and cannot be deterred. The exploration of space will go ahead, whether we join in it or not, and it is one of the great adventures of all time, and no nation which expects to be the leader of other nations can expect to stay behind in this race for space.
Those who came before us made certain that this country rode the first waves of the industrial revolution, the first waves of modern invention, and the first wave of nuclear power, and this generation does not intend to founder in the backwash of the coming age of space. We mean to be a part of it--we mean to lead it. For the eyes of the world now look into space, to the moon and to the planets beyond, and we have vowed that we shall not see it governed by a hostile flag of conquest, but by a banner of freedom and peace. We have vowed that we shall not see space filled with weapons of mass destruction, but with instruments of knowledge and understanding.
Yet the vows of this Nation can only be fulfilled if we in this Nation are first, and, therefore, we intend to be first. In short, our leadership in science and industry, our hopes for peace and security, our obligations to ourselves as well as others, all require us to make this effort, to solve these mysteries, to solve them for the good of all men, and to become the world's leading space-faring nation.
We set sail on this new sea because there is new knowledge to be gained, and new rights to be won, and they must be won and used for the progress of all people. For space science, like nuclear science and all technology, has no conscience of its own. Whether it will become a force for good or ill depends on man, and only if the United States occupies a position of pre-eminence can we help decide whether this new ocean will be a sea of peace or a new terrifying theater of war. I do not say that we should or will go unprotected against the hostile misuse of space any more than we go unprotected against the hostile use of land or sea, but I do say that space can be explored and mastered without feeding the fires of war, without repeating the mistakes that man has made in extending his writ around this globe of ours.
There is no strife, no prejudice, no national conflict in outer space as yet. Its hazards are hostile to us all. Its conquest deserves the best of all mankind, and its opportunity for peaceful cooperation many never come again. But why, some say, the moon? Why choose this as our goal? And they may well ask why climb the highest mountain? Why, 35 years ago, fly the Atlantic? Why does Rice play Texas?
We choose to go to the moon. We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too.
It is for these reasons that I regard the decision last year to shift our efforts in space from low to high gear as among the most important decisions that will be made during my incumbency in the office of the Presidency.
In the last 24 hours we have seen facilities now being created for the greatest and most complex exploration in man's history. We have felt the ground shake and the air shattered by the testing of a Saturn C-1 booster rocket, many times as powerful as the Atlas which launched John Glenn, generating power equivalent to 10,000 automobiles with their accelerators on the floor. We have seen the site where five F-1 rocket engines, each one as powerful as all eight engines of the Saturn combined, will be clustered together to make the advanced Saturn missile, assembled in a new building to be built at Cape Canaveral as tall as a 48 story structure, as wide as a city block, and as long as two lengths of this field.
Within these last 19 months at least 45 satellites have circled the earth. Some 40 of them were made in the United States of America and they were far more sophisticated and supplied far more knowledge to the people of the world than those of the Soviet Union.
The Mariner spacecraft now on its way to Venus is the most intricate instrument in the history of space science. The accuracy of that shot is comparable to firing a missile from Cape Canaveral and dropping it in this stadium between the 40-yard lines.
Transit satellites are helping our ships at sea to steer a safer course. Tiros satellites have given us unprecedented warnings of hurricanes and storms, and will do the same for forest fires and icebergs.
We have had our failures, but so have others, even if they do not admit them. And they may be less public.
To be sure, we are behind, and will be behind for some time in manned flight. But we do not intend to stay behind, and in this decade, we shall make up and move ahead.
The growth of our science and education will be enriched by new knowledge of our universe and environment, by new techniques of learning and mapping and observation, by new tools and computers for industry, medicine, the home as well as the school. Technical institutions, such as Rice, will reap the harvest of these gains.
And finally, the space effort itself, while still in its infancy, has already created a great number of new companies, and tens of thousands of new jobs. Space and related industries are generating new demands in investment and skilled personnel, and this city and this state, and this region, will share greatly in this growth. What was once the furthest outpost on the old frontier of the West will be the furthest outpost on the new frontier of science and space. Houston, your city of Houston, with its Manned Spacecraft Center, will become the heart of a large scientific and engineering community. During the next 5 years the National Aeronautics and Space Administration expects to double the number of scientists and engineers in this area, to increase its outlays for salaries and expenses to $60 million a year; to invest some $200 million in plant and laboratory facilities; and to direct or contract for new space efforts over $1 billion from this center in this city.
To be sure, all this costs us all a good deal of money. This year's space budget is three times what it was in January 1961, and it is greater than the space budget of the previous eight years combined. That budget now stands at $5,400 million a year--a staggering sum, though somewhat less than we pay for cigarettes and cigars every year. Space expenditures will soon rise some more, from 40 cents per person per week to more than 50 cents a week for every man, woman and child in the United States, for we have given this program a high national priority--even though I realize that this is in some measure an act of faith and vision, for we do not now know what benefits await us. But if I were to say, my fellow citizens, that we shall send to the moon, 240,000 miles away from the control station in Houston, a giant rocket more than 300 feet tall, the length of this football field, made of new metal alloys, some of which have not yet been invented, capable of standing heat and stresses several times more than have ever been experienced, fitted together with a precision better than the finest watch, carrying all the equipment needed for propulsion, guidance, control, communications, food and survival, on an untried mission, to an unknown celestial body, and then return it safely to earth, re-entering the atmosphere at speeds of over 25,000 miles per hour, causing heat about half that of the temperature of the sun--almost as hot as it is here today--and do all this, and do it right, and do it first before this decade is out--then we must be bold.
I'm the one who is doing all the work, so we just want you to stay cool for a minute.
However, I think we're going to do it, and I think that we must pay what needs to be paid. I don't think we ought to waste any money, but I think we ought to do the job. And this will be done in the decade of the Sixties. It may be done while some of you are still here at school at this college and university. It will be done during the terms of office of some of the people who sit here on this platform. But it will be done. And it will be done before the end of this decade.
And I am delighted that this university is playing a part in putting a man on the moon as part of a great national effort of the United States of America.
Many years ago the great British explorer George Mallory, who was to die on Mount Everest, was asked why did he want to climb it. He said, "Because it is there."
Well, space is there, and we're going to climb it, and the moon and the planets are there, and new hopes for knowledge and peace are there. And, therefore, as we set sail we ask God's blessing on the most hazardous and dangerous and greatest adventure on which man has ever embarked.
Thank you.

in our daily lives, we have many choices to make, such as what to eat for supper,what clothes to wear, or what to do on weekends. at certain times in our lives, we need to make even more critical choices, such as which school to attend, what job to take or who to choose as husband or wife. yes, life is a matter of choice. seemimgly, it means a choice of tangible things. but in essence, it means choosing a way of life. life is to be lived, savored, and enjoyed, not to be wasted or complained about.
hardly can we forget the time when our society faced the grave threat from the life-and-death disease--sars. yet, even during those dreadful times, some afflicted people remained optimistic. instead of wearing neutral white masks, some people turned to colouful ones, and thus display a happy mood. and some creative people dubbed sars to mean "smile and remain smiling." i was deeply touched by their optimisim, nearly forgetting that we're still in a battle. people who survive these kinds of circumstances, (at some point)decide in their minds to carry on in spite of the overwhelming odds.
laid-off workers, typically regarded as the victims of economic advancement, are subject to desperation that being unmeployed has brought on them. but, encouragingly, we have witnessed some of them striving hard to rebuild confidence toward life and discover new opportunities for demonstrating their values.
although we cannot choose our appearance, inborn gifts and even avoid unexpected disasters and adversities, we do have the privilege to choose to live optimistcally,to love our lives, to have dreams, and to cherish hopes.
every morning when we get up, we have a choice of how we want to approach life that day. as for me, i choose to be cheerful.
日常生活中,我们会面临各种各样的选择,像是晚餐吃什么,穿什么或是如何度周末。而在人生中的特定阶段,我们需要做出更多关键性的抉择,例如教育,职业或者人生伴侣。生活就意味着一种选择。这种选择看似是对具体事物的判断,但归根究底,是一种生活方式的选择。任何无味的抱怨和虚度光阴只会带来乏味,生活的美需要细心品尝,用心体会。
如今回想起那段笼罩在sars阴影下的日子依然心有余悸。但即便在那样令人沮丧的日子里,备受折磨的人们也始终保持着乐观。为传递一种欢快的情绪,大家换上了色彩缤纷的口罩。而那些富有创造力的人则把sars解释为"笑口常开"。他们对待生活的乐观态度深深打动了我,几乎让我忘记我们还身处在没有硝烟的战场。其实,正是坚持不懈,坚忍不拔的精神引领人们走出了逆境。
被看做经济发展牺牲品的广大下岗职工在面对生存压力时,特别容易陷入绝望当中。但别人欣慰的是,我们看到越来越多的这个群体中的成员重建了对生活的信心,并重新立足于社会以实现自己的价值。
尽管容貌和天资都是上苍给予,而人生旅途中的坎坷与荆棘我们也无法预计,那就让我们热爱生命,拥有梦想,珍惜希望吧。
每日清晨梦醒,我们都被赋予了选择生活的权利。而我会让一切从愉快开始。

Hello everyone,Today, I want to talk about the power of faith. Faith is a powerful force that shapes our lives and gives us purpose. It is the foundation of our beliefs, values, and actions.
Faith can help us overcome challenges and difficulties. When we have a belief in something, we are more likely to persevere and work towards our goals. It can also help us find meaning and purpose in life. When we have faith in ourselves and our abilities, we are more likely to achieve our goals and reach our dreams.
Faith can also bring us closer to our loved ones and friends. When we have faith in our relationships and the people in our lives, we are more likely to be compassionate, kind, and supportive. It can also help us connect with our spirituality and have a deeper understanding of the world around us.
But faith is not just about belief in something. It is also about being open-minded and accepting change. When we have faith in something, we are more likely to be patient and understanding when things don't go as planned. We are also more likely to be open to new ideas and perspectives, which can help us grow and evolve as individuals.
In conclusion, faith is a powerful force that shapes our lives and gives us purpose. It can help us overcome challenges and difficulties, bring us closer to our loved ones, and connect us with our spirituality. Whether we are religious or not, faith is a fundamental aspect of our lives that can help us live meaningful and fulfilling lives. Thank you.

My mother has very long hair, and wears a pair of small glasses, neverloves wearing fashionable clothes, but loves reading modern books. She isknowledgable and loves writing.
I think her working is often exactly alike my father--investment, tireless,efficient,and pursuit of perfection.
She loves to be angry and excited very much; be silence and talkative aswell. In short, there have "four seasons" of different moods in a day.
My mother always loves to say “case by case”. Whatever I do, rightness orwrong, she loves me. That's true, such as when I examined well, she neverpraised, but let me try hard again; when not well, she was not angry (sometimesexceptions, but very few), but let me do better!
I have such a good mother, I’m very happy! May mother happy every day!Maymother young forever! Thank you!
我的妈妈长着长长的头发,戴着一副小眼镜,从不爱穿时髦的衣服,但爱看时髦的书。知识丰富,喜爱写作。
我觉得她做事、干活都和爸爸一模一样——投入、不知疲倦、高效、追求完美。
她很爱生气,又很爱兴奋;既爱沉默,又很健谈。总之,一天就有情绪“四季”。
我妈妈总是爱说“就事论事”,不管我做得对与错,她都爱我。的确这样,比如我考试好了,她不表扬,却让我再努力;考不好,她也不生气(有时例外,但很少),而是帮助我做得更好!
我有这样一个好妈妈,可真幸福啊!祝妈妈天天开心,永远年轻!
谢谢大家!

ladies and gentlemen,
for lives in schoolyards, i think:that's the studying place we're most familiar with。some people say:studying is the very and most boring thing,and i have even include the life in school。but i think studying is a very joyous thing,life in school is very interesting,it forms a picture of life,made my road of life be filled with happiness and enrichment。my life in school is like a slowly flowing stream,it flows happily,with occasions of small waves。lift your head up, it's spring,bow your head down, it's fall,the full moon as a picture,the crescent as a poem。my life in school lived in the silence of time.
it's morning,with the cool winds accompanying me,small groups of students arrived at class。in the morning reading class,everyone opened up their books,together they read the textbook entries aloud,sometimes their would be some students that does not read aloud,but under the teachers governance,everyone all read aloud,it became a unmissable schoolyard orchestra in the schoolyard。a bran new day at school just begun。 every-time we saw the teacher's professional figure,our hearts would go with the teacher into the sea of knowledge,to feel the
traditions of other countries,to feel the fresh sunshine in another world、the feel the world's brightness。
breaks are relaxing,in the hallways,some students are talking,some students are looking at the sceneries,relaxing their weary minds。in the classrooms,some students are reading story books,some students are doing homework,and some students are making preparation for next class
the favorite class of students would be physical education。in physical education,they can run freely,enjoying the sun's shines,making themselves sweaty。see,the students are playing basketball over on that field,they are playing badminton,and they are playing ping-pong in the court on the east side of the area......
near dawn,students all anxious to get home with their textbooks,they talk and laugh,feeling happy for another joyful day。
my life in school is very sweet。because in there there are familiar faces;sweet laughters;sentences wishing me good luck。in our days of succession,we scream for joy,we share the goodness of succession;make music using notes that touch our hearts。in our days of failure,we courage each other on,work together。at the same time,i want to thank my teachers,“the
end of the sky and earth can be broken,but only the heart for the teacher cannot be forgotten。”every time that i was down,sad because of the failed test,my teacher would be like a bright light guiding my lost soul,teaching me、allowing me to be a strong man,because succession only belongs to the leaders of life。
life in the schoolyard is very tensing, busy, and hard-working, but it's also very sweetening, joyous, and colorful. i love my life in this school.

Me and my Fears
Honorable judges, distinguished guests, ladies and gentlemen:
It is a great honor and pleasure to be here on this beautiful Saturday morning to share with you my sentiments about life and passion for the English language.
About a year and a half ago, I took part in my very first English Speech Contest. When I stood before the microphone with all eyes starring directly at me, I could hardly speak. I stood there, embarrassed and helpless, struggling in vain for the right thing to say. My fears had paralyzed me.
While my passion for English has never changed, I lost my courage to speak in public. When my professor again encouraged me to take part in this Competition, I said “no.” I couldn’t endure yet another painful experience. He looked me straight in the eye and said something that pierced my heart. I will never forget his words. “Look,” he said, “We all have our fears, and you have yours. You could twist your ankle in a basketball game, but then be afraid to ever play again. Running away can never dispel your fears, but action will. A winner is not one who never fails,but one who never quits.”
I spent a whole day with his words twisting and turning in my mind. Then I made the bravest and wisest decision of my life: I would face my fears – and take part in the competition!
As it turned out, my dear old professor was right. Now, here I am, once again standing before a microphone. My heart is beating fast, and my mouth is dry, but most importantly, I have faced my fears -- and that makes all the difference!
Thank you.
战胜恐惧
尊敬的评委,各位来宾,女士们先生们,我很荣幸在这个美妙的星期六早上来到这里,与你们分享我生命中一段特别的经历。
大概一年半以前,我参加了生平第一次演讲比赛。站在麦克风前,面对观众们期待的眼神,我竟紧张的说不出话来。那一刻,我是多么无助啊!
我对于英语的挚爱从未改变,但却从此失去了面对公众演讲的勇气。当老教授鼓励我参加希望英语风采大赛时,我拒绝了。他直视我的眼睛,说了一番令我终身难忘的话。“你瞧,”他说,“我们都有自己的恐惧。你可能会在一场篮球比赛中扭脚,并从此害怕再打球。你只能用行动去克服自己的恐惧,逃避是没有用的。生活中的成功者往往是永不放弃的人。”
我花了一整天时间思考他的话。 然后,我做出了一个勇敢而明智的决定: 我要参加中央电视台第五届“希望之星”英语风采大赛!
老教授是对的。我发挥出了自己的水平,一路杀进了全国总决赛。此时此刻,当我再一次站在了麦克风前,仍然心跳不止,但更重要的是,我终于能够勇敢地面对我的恐惧了,而这已足够了。

With the tool of OpenGL andMatlab, I designed a simulationprogram for transportation scheduling system. Itis now widely used by different research groups in NUST. I assumed and fulfilleda sewage analysis &; dispose project for Nanjing sewagetreatment plant. Thiswas my first practice to convert a laboratory idea to a commercial product.
In retrospect, I find myself standing on a solid basis in both theory andexperience, which has prepared me for the Ph.D. program. My future researchinterests include: Network Scheduling Problem, Heuristic Algorithm research(especially in GA and Neural network), Supply chain network research, Hybridsystem performance analysis with Petri nets and Data Mining.

There is no doubt that the arts festival enriches our college life an extracurricular activity. However when it comes to what should be included in the arts festival different people have different views. Some insists on performing arts such as dances and dramas. Still others argue for the work of art like paintings and calligraphy. Personally I agree with the latter and I strongly recommend that photographic works should be counted as an important aspect of the arts festival.
毫无疑问,艺术节丰富了我们大学生活中的课外活动。然而,每当说起艺术节该包含什么节目,不同的人有不同的想法。有些人坚持表演艺术,像舞蹈和话剧。有些人辩论说应该也有绘画和书法的作品。个人来说,我同意后者而且我强烈推荐摄影作为艺术节中重要的一部分。
My suggestion lies in the following two reasons. On the one hand for he students who take photos the photographic exhibition can stimulate them to discover the beauty that permeates our surroundings. As the saying goes beauty is in the eye of the beholder; such an activity will definitely foster sharp eyes of photographers to-be. On the other hand for the students who appreciate the photos they are given a shortcut to the beauty of the nature and the society. Maybe by this way they find the sense of the life and enjoy the life more in the future.
我的建议基于以下两点。从一方面来说,对于拍照的同学,摄影展示能够激发他们去发现我们身边的美。常言道,美在观察者的眼中;像这种活动绝对能够培养未来摄影者的锐利目光。从另一方面来说,对于喜欢照片的同学来说,他们就有了一条通向自然和社会的美景的捷径了。也许通过这个方式,他们能够找到生活的感觉,未来也会更加享受生活。
In short the photographic exhibition can get the students to discover and appreciate beauty. I believe that it is wise to involve the photographic works into the university arts festival.
简言之,摄影展能够让同学发现和欣赏美。我相信把摄影展加入到大学艺术节是明智的。

What life is about
As we all know, the most important thing in life is our attitude towards it, tons of men have tried different ways of treating life, and some succeeded, some failed, and here are some of the tips they left us.
Life isn’t about keeping score. Life isn’t about your shoes or your hair or the color of your skin. In fact it’s not about if you have lots of friends or if you are alone, and it’s not about how accepted or unaccepted you are. Life just isn’t about that.
But life is about whom you love and who you hurt. It’s about how you feel about yourself. It’s about trust, happiness and compassion. It’s about sticking up for your friends and replacing inner hate with love. Life is about avoiding jealousy, overcoming ignorance and building confidence. It’s about what you say and what you mean. It’s about seeing people for who they are and not what they have. And we should always remember to be ourselves. Other might have things that we desire but being what we really are is the only trail leading to the true colors of life. Most of all, it’s about choosing to use your life to touch someone else’s in a way that could have never been achieved otherwise.
The paradox of our time in history is that we have taller buildings but shorter tempers; we buy more but enjoy them less. We’ve learnt how to make a living but not a life, we’ve added years to life, but not life to years. And it is time for us to choose whether to make a difference in our life.
And these choices are what life is about.
生活的真谛
众所周知,关于生活最重要的我们对待生活的态度,不同的人以不同的方式对待生活,一些人成功了,一些人失败了。这里有一些关于生活的帖士给我们大家。
生活不是为了保持高分,生活也不仅仅是你的鞋子、你的发型和你的肤色。实际上,生活也不只是你拥有多少朋友,或者你是否孤独;生活也不仅仅意味着你被别人接受与否。生活并不仅仅是这些。
但是,生活是关于你所爱的和你所伤害的那些人。生活就是你对自己的所有感觉。它是关于信任、幸福和包容。它是你对朋友的支持和如何用爱来融化内心的憎恨。生活就是远离嫉妒、克服无知和建立信心。生活是关于你的言行和思想。
生活就是关注人的自身,而不是关注别人的拥有。而且我们必须记住保持我们的本色。虽然,生活的另一面令我们向往,但保持我们的本色是通往生活真谛的必由之路。总之,生活就是用你整个的生命去触摸其他人从未企及的选择。 在生活的长河中也常常令我们困惑和矛盾,我们拥有越来越高大的建筑,但我们也越来越缺乏耐心;我们购买的物质越来越多,但我们从中得到的快乐越来越少。我们学习如何活着但那却不是生活;人类的寿命越来越长,但有意义的生活并因此而延长。因此,现在正是我们选择使我们的人生变得不同凡响的时候了。初中英语演讲稿这些选择就是生活的真谛。

one day, god said to a priest: ‘come, and i want to take you to see the hell.” they entered a room where so many people were sitting around a cooking pot. they looked at it but no one wants to say or do anything. they felt not only hungry but also disappointed .everyone has a spoon. but the handle of the spoon were too long for the food to be sent into their mouths.
有一天,上帝的牧师说:'来吧,我要带你看地狱“他们进入一个房间里这么多人坐在周围的锅。。他们看着它,但没有人愿意说或做任何事情。他们认为不仅饥饿,但也感到失望。每个人都有一个勺子。但勺子的柄太长时间的食物到他们口中发出。
“come, now i want to take you to the heaven. ”god took the priest to the heaven and entered another room. this room was the same as the first one. there were so many people sitting around a cooking pot, and the handles of their spoon were as long as those of the first group of people. there was nothing different but the atmosphere. people here drank and ate, speaking and laughing. the priest felt puzzled and asked god. god answered with a smile. ”can’t you see? people in the second room here learnt to feed each other “ the priest suddenly saw the light.
“来吧,现在我要带你到天堂。 “上帝的神父到了天堂,进入另一个房间。这间屋子作为第一个相同。有这么多身边的人一个锅坐着,他们的勺子手柄一样的第一组的人长。没有什么不同,但气氛。这里的人喝酒,吃饭,说话和笑。神父感到不解地问上帝。上帝微笑着回答。 “你没看见?在第二个房间里学会了喂对方“牧师人们突然看到了光明。
this story tells us that we should learn to share and give, and develop the good habit of loving and helping one another. the niggards who we saw in the hell would rather make themselves hungry than share with others.
这个故事告诉我们,我们应该学会分享,给予,爱和发展互相帮助的好习惯。我们在地狱看到了,那些人宁愿让自己比其他人分享饿了。
as a british poet said:” taken away love, our earth would be a grave. sharing is an idea state, a wisdom and distillation. sharing love, happiness and sadness is all that we need. there are so many people who don’t want to share with others .whatever they do they will think about themselves first. these people can never understand the real meaning of sharing. people are always imagining that they can live a good life in the heaven .because of imagination, we always feel we are far away from the heaven .in fact, the heaven is not far away from us .
作为英国诗人说:“采取了爱,我们的地球将会是一个严重。分享是一种思想状态,智慧和升华。分享爱,快乐和悲伤是所有我们需要的。有这么多的人谁不想与别人分享。无论他们这么做,他们将第一次对自己的看法。这些人永远无法理解共享的真正意义。人们总是想象他们可以住在天堂的生活,因为一个良好的想象力。,我们总是觉得我们远离天堂。事实上,天堂离我们并不遥远。

What I'd like to do today is talk about one of my favorite subjects, and that is the neuroscience of sleep.
Now, there is a sound -- (Alarm clock) -- aah, it worked -- a sound that is desperately, desperately familiar to most of us, and of course it's the sound of the alarm clock. And what that truly ghastly, awful sound does is stop the single most important behavioral experience that we have, and that's sleep. If you're an average sort of person, 36 percent of your life will be spent asleep, which means that if you live to 90, then 32 years will have been spent entirely asleep.
Now what that 32 years is telling us is that sleep at some level is important. And yet, for most of us, we don't give sleep a second thought. We throw it away. We really just don't think about sleep. And so what I'd like to do today is change your views, change your ideas and your thoughts about sleep. And the journey that I want to take you on, we need to start by going back in time.
"Enjoy the honey-heavy dew of slumber." Any ideas who said that? Shakespeare's Julius Caesar. Yes, let me give you a few more quotes. "O sleep, O gentle sleep, nature's soft nurse, how have I frighted thee?" Shakespeare again, from -- I won't say it -- the Scottish play. [Correction: Henry IV, Part 2] (Laughter) From the same time: "Sleep is the golden chain that ties health and our bodies together." Extremely prophetic, by Thomas Dekker, another Elizabethan dramatist.
But if we jump forward 400 years, the tone about sleep changes somewhat. This is from Thomas Edison, from the beginning of the 20th century. "Sleep is a criminal waste of time and a heritage from our cave days." Bang. (Laughter) And if we also jump into the 1980s, some of you may remember that Margaret Thatcher was reported to have said, "Sleep is for wimps." And of course the infamous -- what was his name? -- the infamous Gordon Gekko from "Wall Street" said, "Money never sleeps."
What do we do in the 20th century about sleep? Well, of course, we use Thomas Edison's light bulb to invade the night, and we occupied the dark, and in the process of this occupation, we've treated sleep as an illness, almost. We've treated it as an enemy. At most now, I suppose, we tolerate the need for sleep, and at worst perhaps many of us think of sleep as an illness that needs some sort of a cure. And our ignorance about sleep is really quite profound.
Why is it? Why do we abandon sleep in our thoughts? Well, it's because you don't do anything much while you're asleep, it seems. You don't eat. You don't drink. And you don't have sex. Well, most of us anyway. And so therefore it's -- Sorry. It's a complete waste of time, right? Wrong. Actually, sleep is an incredibly important part of our biology, and neuroscientists are beginning to explain why it's so very important. So let's move to the brain.
Now, here we have a brain. This is donated by a social scientist, and they said they didn't know what it was, or indeed how to use it, so -- (Laughter) Sorry. So I borrowed it. I don't think they noticed. Okay. (Laughter)
The point I'm trying to make is that when you're asleep, this thing doesn't shut down. In fact, some areas of the brain are actually more active during the sleep state than during the wake state. The other thing that's really important about sleep is that it doesn't arise from a single structure within the brain, but is to some extent a network property, and if we flip the brain on its back -- I love this little bit of spinal cord here -- this bit here is the hypothalamus, and right under there is a whole raft of interesting structures, not least the biological clock. The biological clock tells us when it's good to be up, when it's good to be asleep, and what that structure does is interact with a whole raft of other areas within the hypothalamus, the lateral hypothalamus, the ventrolateral preoptic nuclei. All of those combine, and they send projections down to the brain stem here. The brain stem then projects forward and bathes the cortex, this wonderfully wrinkly bit over here, with neurotransmitters that keep us awake and essentially provide us with our consciousness. So sleep arises from a whole raft of different interactions within the brain, and essentially, sleep is turned on and off as a result of a range of
Okay. So where have we got to? We've said that sleep is complicated and it takes 32 years of our life. But what I haven't explained is what sleep is about. So why do we sleep? And it won't surprise any of you that, of course, the scientists, we don't have a consensus. There are dozens of different ideas about why we sleep, and I'm going to outline three of those.
The first is sort of the restoration idea, and it's somewhat intuitive. Essentially, all the stuff we've burned up during the day, we restore, we replace, we rebuild during the night. And indeed, as an explanation, it goes back to Aristotle, so that's, what, 2,300 years ago. It's gone in and out of fashion. It's fashionable at the moment because what's been shown is that within the brain, a whole raft of genes have been shown to be turned on only during sleep, and those genes are associated with restoration and metabolic pathways. So there's good evidence for the whole restoration hypothesis.
What about energy conservation? Again, perhaps intuitive. You essentially sleep to save calories. Now, when you do the sums, though, it doesn't really pan out. If you compare an individual who has slept at night, or stayed awake and hasn't moved very much, the energy saving of sleeping is about 110 calories a night. Now, that's the equivalent of a hot dog bun. Now, I would say that a hot dog bun is kind of a meager return for such a complicated and demanding behavior as sleep. So I'm less convinced by the energy conservation idea.
But the third idea I'm quite attracted to, which is brain processing and memory consolidation. What we know is that, if after you've tried to learn a task, and you sleep-deprive individuals, the ability to learn that task is smashed. It's really hugely attenuated. So sleep and memory consolidation is also very important. However, it's not just the laying down of memory and recalling it. What's turned out to be really exciting is that our ability to come up with novel solutions to complex problems is hugely enhanced by a night of sleep. In fact, it's been estimated to give us a threefold advantage. Sleeping at night enhances our creativity. And what seems to be going on is that, in the brain, those neural connections that are important, those synaptic connections that are important, are linked and strengthened, while those that are less important tend to fade away and be less important.
Okay. So we've had three explanations for why we might sleep, and I think the important thing to realize is that the details will vary, and it's probable we sleep for multiple different reasons. But sleep is not an indulgence. It's not some sort of thing that we can take on board rather casually. I think that sleep was once likened to an upgrade from economy to business class, you know, the equiavlent of. It's not even an upgrade from economy to first class. The critical thing to realize is that if you don't sleep, you don't fly. Essentially, you never get there, and what's extraordinary about much of our society these days is that we are desperately sleep-deprived.
So let's now look at sleep deprivation. Huge sectors of society are sleep-deprived, and let's look at our sleep-o-meter. So in the 1950s, good data suggests that most of us were getting around about eight hours of sleep a night. Nowadays, we sleep one and a half to two hours less every night, so we're in the six-and-a-half-hours-every-night league. For teenagers, it's worse, much worse. They need nine hours for full brain performance, and many of them, on a school night, are only getting five hours of sleep. It's simply not enough. If we think about other sectors of society, the aged, if you are aged, then your ability to sleep in a single block is somewhat disrupted, and many sleep, again, less than five hours a night. Shift work. Shift work is extraordinary, perhaps 20 percent of the working population, and the body clock does not shift to the demands of working at night. It's locked onto the same light-dark cycle as the rest of us. So when the poor old shift worker is going home to try and sleep during the day, desperately tired, the body clock is saying, "Wake up. This is the time to be awake." So the quality of sleep that you get as a night shift worker is usually very poor, again in that sort of five-hour region. And then, of course, tens of millions of people suffer from jet lag. So who here has jet lag? Well, my goodness gracious. Well, thank you very much indeed for not falling asleep, because that's what your brain is craving.
One of the things that the brain does is indulge in micro-sleeps, this involuntary falling asleep, and you have essentially no control over it. Now, micro-sleeps can be sort of somewhat embarrassing, but they can also be deadly. It's been estimated that 31 percent of drivers will fall asleep at the wheel at least once in their life, and in the U.S., the statistics are pretty good: 100,000 accidents on the freeway have been associated with tiredness, loss of vigilance, and falling asleep. A hundred thousand a year. It's extraordinary. At another level of terror, we dip into the tragic accidents at Chernobyl and indeed the space shuttle Challenger, which was so tragically lost. And in the investigations that followed those disasters, poor judgment as a result of extended shift work and loss of vigilance and tiredness was attributed to a big chunk of those disasters.
So when you're tired, and you lack sleep, you have poor memory, you have poor creativity, you have increased impulsiveness, and you have overall poor judgment. But my friends, it's so much worse than that.
(Laughter)
If you are a tired brain, the brain is craving things to wake it up. So drugs, stimulants. Caffeine represents the stimulant of choice across much of the Western world. Much of the day is fueled by caffeine, and if you're a really naughty tired brain, nicotine. And of course, you're fueling the waking state with these stimulants, and then of course it gets to 11 o'clock at night, and the brain says to itself, "Ah, well actually, I need to be asleep fairly shortly. What do we do about that when I'm feeling completely wired?" Well, of course, you then resort to alcohol. Now alcohol, short-term, you know, once or twice, to use to mildly sedate you, can be very useful. It can actually ease the sleep transition. But what you must be so aware of is that alcohol doesn't provide sleep, a biological mimic for sleep. It sedates you. So it actually harms some of the neural proccessing that's going on during memory consolidation and memory recall. So it's a short-term acute measure, but for goodness sake, don't become addicted to alcohol as a way of getting to sleep every night.
Another connection between loss of sleep is weight gain. If you sleep around about five hours or less every night, then you have a 50 percent likelihood of being obese. What's the connection here? Well, sleep loss seems to give rise to the release of the hormone ghrelin, the hunger hormone. Ghrelin is released. It gets to the brain. The brain says, "I need carbohydrates," and what it does is seek out carbohydrates and particularly sugars. So there's a link between tiredness and the metabolic predisposition for weight gain.
Stress. Tired people are massively stressed. And one of the things of stress, of course, is loss of memory, which is what I sort of just then had a little lapse of. But stress is so much more. So if you're acutely stressed, not a great problem, but it's sustained stress associated with sleep loss that's the problem. So sustained stress leads to suppressed immunity, and so tired people tend to have higher rates of overall infection, and there's some very good studies showing that shift workers, for example, have higher rates of cancer. Increased levels of stress throw glucose into the circulation. Glucose becomes a dominant part of the vasculature and essentially you become glucose intolerant. Therefore, diabetes 2. Stress increases cardiovascular disease as a result of raising blood pressure. So there's a whole raft of things associated with sleep loss that are more than just a mildly impaired brain, which is where I think most people think that sleep loss resides.
So at this point in the talk, this is a nice time to think, well, do you think on the whole I'm getting enough sleep? So a quick show of hands. Who feels that they're getting enough sleep here? Oh. Well, that's pretty impressive. Good. We'll talk more about that later, about what are your tips.
So most of us, of course, ask the question, "Well, how do I know whether I'm getting enough sleep?" Well, it's not rocket science. If you need an alarm clock to get you out of bed in the morning, if you are taking a long time to get up, if you need lots of stimulants, if you're grumpy, if you're irritable, if you're told by your work colleagues that you're looking tired and irritable, chances are you are sleep-deprived. Listen to them. Listen to yourself.
What do you do? Well -- and this is slightly offensive -- sleep for dummies: Make your bedroom a haven for sleep. The first critical thing is make it as dark as you possibly can, and also make it slightly cool. Very important. Actually, reduce your amount of light exposure at least half an hour before you go to bed. Light increases levels of alertness and will delay sleep. What's the last thing that most of us do before we go to bed? We stand in a massively lit bathroom looking into the mirror cleaning our teeth. It's the worst thing we can possibly do before we went to sleep. Turn off those mobile phones. Turn off those computers. Turn off all of those things that are also going to excite the brain. Try not to drink caffeine too late in the day, ideally not after lunch. Now, we've set about reducing light exposure before you go to bed, but light exposure in the morning is very good at setting the biological clock to the light-dark cycle. So seek out morning light. Basically, listen to yourself. Wind down. Do those sorts of things that you know are going to ease you off into the honey-heavy dew of slumber.
Okay. That's some facts. What about some myths?
Teenagers are lazy. No. Poor things. They have a biological predisposition to go to bed late and get up late, so give them a break.
We need eight hours of sleep a night. That's an average. Some people need more. Some people need less. And what you need to do is listen to your body. Do you need that much or do you need more? Simple as that.
Old people need less sleep. Not true. The sleep demands of the aged do not go down. Essentially, sleep fragments and becomes less robust, but sleep requirements do not go down.
And the fourth myth is, early to bed, early to rise makes a man healthy, wealthy and wise. Well that's wrong at so many different levels. (Laughter) There is no, no evidence that getting up early and going to bed early gives you more wealth at all. There's no difference in socioeconomic status. In my experience, the only difference between morning people and evening people is that those people that get up in the morning early are just horribly smug.
(Laughter) (Applause)
Okay. So for the last part, the last few minutes, what I want to do is change gears and talk about some really new, breaking areas of neuroscience, which is the association between mental health, mental illness and sleep disruption. We've known for 130 years that in severe mental illness, there is always, always sleep disruption, but it's been largely ignored. In the 1970s, when people started to think about this again, they said, "Yes, well, of course you have sleep disruption in schizophrenia because they're on anti-psychotics. It's the anti-psychotics causing the sleep problems," ignoring the fact that for a hundred years previously, sleep disruption had been reported before anti-psychotics.
So what's going on? Lots of groups, several groups are studying conditions like depression, schizophrenia and bipolar, and what's going on in terms of sleep disruption. We have a big study which we published last year on schizophrenia, and the data were quite extraordinary. In those individuals with schizophrenia, much of the time, they were awake during the night phase and then they were asleep during the day. Other groups showed no 24-hour patterns whatsoever. Their sleep was absolutely smashed. And some had no ability to regulate their sleep by the light-dark cycle. They were getting up later and later and later and later each night. It was smashed.
So what's going on? And the really exciting news is that mental illness and sleep are not simply associated but they are physically linked within the brain. The neural networks that predispose you to normal sleep, give you normal sleep, and those that give you normal mental health are overlapping. And what's the evidence for that? Well, genes that have been shown to be very important in the generation of normal sleep, when mutated, when changed, also predispose individuals to mental health problems. And last year, we published a study which showed that a gene that's been linked to schizophrenia, which, when mutated, also smashes the sleep. So we have evidence of a genuine mechanistic overlap between these two important systems.
Other work flowed from these studies. The first was that sleep disruption actually precedes certain types of mental illness, and we've shown that in those young individuals who are at high risk of developing bipolar disorder, they already have a sleep abnormality prior to any clinical diagnosis of bipolar. The other bit of data was that sleep disruption may actually exacerbate, make worse the mental illness state. My colleague Dan Freeman has used a range of agents which have stabilized sleep and reduced levels of paranoia in those individuals by 50 percent.
So what have we got? We've got, in these connections, some really exciting things. In terms of the neuroscience, by understanding the neuroscience of these two systems, we're really beginning to understand how both sleep and mental illness are generated and regulated within the brain. The second area is that if we can use sleep and sleep disruption as an early warning signal, then we have the chance of going in. If we know that these individuals are vulnerable, early intervention then becomes possible. And the third, which I think is the most exciting, is that we can think of the sleep centers within the brain as a new therapeutic target. Stabilize sleep in those individuals who are vulnerable, we can certainly make them healthier, but also alleviate some of the appalling symptoms of mental illness.
So let me just finish. What I started by saying is take sleep seriously. Our attitudes toward sleep are so very different from a pre-industrial age, when we were almost wrapped in a duvet. We used to understand intuitively the importance of sleep. And this isn't some sort of crystal-waving nonsense. This is a pragmatic response to good health. If you have good sleep, it increases your concentration, attention, decision-making, creativity, social skills, health. If you get sleep, it reduces your mood changes, your stress, your levels of anger, your impulsivity, and your tendency to drink and take drugs. And we finished by saying that an understanding of the neuroscience of sleep is really informing the way we think about some of the causes of mental illness, and indeed is providing us new ways to treat these incredibly debilitating conditions.
Jim Butcher, the fantasy writer, said, "Sleep is God. Go worship." And I can only recommend that you do the same.
Thank you for your attention.
(Applause)

With the development of our society, energy in the world bees more and morelimited, so it is quite important for us to save energy and to protect ourenvironment。 As a student, there are a lot of methods we can do to save energyat home。 For example, first, we can turn off the light as well as otherappliances when we are not using them。 Second, recycle the waste water, paperand other waste so that we can reuse them。 What's more, it is suggested to usepublic transportation more instead of private cars。
Above all, everyone can make a great contribution to our environment。 Ihope I can learn more to develop new and clear energy, like energy from the windand solar。

they have met in business. they have met in education. they have met in the arts. some people will argue that these meetings will leave us with a choice between east and west, but i believe that the best future lies in the creative combination of both worlds. we can make western ideas, customs and technology our own, and adapt them to our own use. we can enjoy the best of both worlds, because our tradition is, above all, one of selecting the best and ma-ki-ng it our own.
i love beijing and hennan opera because it always reminds me of who i am. but i am also a fan of pop music, especially english songs. so i have combined eastern melody with western language. it is called western henna opera.
when two cultures meet, there may be things in one culture, which do not fit into the tradition of the other. when this happens, we need to learn to understand and respect the(customs of another culture. then there are certain things some people may not like. to this, i will say, if you do not like it, please try to tolerate it. to learn to tolerate what you personally don’t like is a great virtue at a time when different cultures mix and merge. before us, there are two rivers, eastern and western cultures. at present, they may run in different courses. but eventually, they will converge into the vast sea of human culture.
right now, i can see peoples of eastern and western cultures, standing side by side, singing the olympic theme song: we are hand in hand, heart to heart, together we will shape a beautiful tomorrow! thank you!
让我们共同感受东西方的融合
吉卜林说过:东方是东方,西方是西方,二者永不相聚。但是一个世纪后的今天,东西方相汇了! 它们相聚在经济领域,它们相聚在教育领域,它们相聚在艺术的殿堂。有人争论说:这种融合需要我们在东方和西方之间做出选择,但我却坚信最美好的未来在于东方和西方创造性的融合。我们可以将西方的思想,观念和技术变为我们自己所用的东西。
我喜爱京剧和河南豫剧,因为它们经常使我想起自己是谁。但我也热衷于流行音乐,特别是英文歌曲。于是我将东方的旋律和西方的语言结合到了一起,它叫做西方版的河南豫剧。
当两种文化相结合的时候,也许一方的文化中的.某些东西不适应另一方的传统文化。当此种情况出现时,我们需要试着理解并接受另一种文化中的风俗习惯。然而,也许有些东西你并不喜欢,对于此,我可以说,如果你不喜欢它,请试着去容忍它。当两种文化融合的时候,试着去容忍你个人不喜欢的东西是一种美德。

honourable judges and friends,
good morning! i am very glad to be here to share my college life with you .
two years ago, i came into this city of and started my college life , the most memorable journey of my life. i was just a shy and little girl that time. all the things seemed fresh to me: new faces, large library and physics lab etc. i breathed the air of college greedily, i was curious about everything.the class given by the teachers are excellent.they provide us with information not only from our textbook but from other sources as well.i actively involved in student union and varies of association. but soon i realized that i do not make full use of my spare time ,so i got a part-time job to help a junior student with math lessons besides,i also took part in activities concerning public welfare. we taught the kids there who could not afford school, i was deeply touched by their eagerness to learn, the precious experience with the poor kids made me aware of the responsibility on the shoulders of us--future teachers. the enrichment of experience taught me the significance of modesty,responsibility,tolerance,and perseverance.
and now i have been here two years. recalling to the two years, i think i have to talk about one thing--learning. learn how to study independently, learn how to get along with others, learn to love, learn to… oh, there are too much things we have to learn.
comparing with senior high school, college is a rather different place. there aren’t so many people to watch you and guide you how to do something any more, neither are there so many students who share with you one dream. in college, you must think and study yourself, so you have to learn and practice to control yourself.
another relationship in college is friendship. my roommates have lived two years with me. in these years, they forgive my faults, cry with me, laugh with me, play with me… they always stand with me and support me, i have learned a lot from them. i love them all and treasure the friendship with them.
in the next 2 years,i’ll try my best to and make great contributions to society! that’s my college life. i cherish all i have experienced in college. i love you, my college!
that’s all, thank you!

Hello,every!today I’m glad to give you a speech of “the youthdream”.
First I want to ask you some questions: Do you know what is youth? How do you master your youth? Different people may have different answers. In my eyes, youth is not rosy cheeks,red lips and supple knees. It is a matter of the emotion: it is the freshness, it is the freshness of the deep spring of life.Martin Luther King had said:
I have a dream today. I have a dream that one day every vally shall be exalted, every hill and mountain shall be made low, the rough places will be made plain, and the crooked places will be made straight, and the glory of the Lord shall be revealed, and all flesh shall see it together.
Wow, what a dream it has been for Martin Luther King.But the changing world seems telling me that people gradually get their dreams lost somehow in the process of growing up, and sometimes I personally find myself saying goodbye unconsciously to those distant childhood dreams.
However, we need dreams. They nourish our spirit; they represent possibility even when we are dragged down by reality. They keep us going. Most successful people are dreamers as well as ordinary people who are not afraid to think big and dare to be great.When we were little kids, we all dreamed of doing something big and splashy, something significant.Now what we need to do is to maintain them, refresh them and turn them into reality. However, the toughest part is that we often have no ideas how to translate these dreams into actions. Well, just start with concrete objectivity, we will make it.
Hold fast to dreams, for if dreams die, life is a broken-winged bird that cannot fly. Hold fast to dreams, for when dreams go, life is a barren field frozen with snow. So my dear friends, think of your old and maybe dead dreams. Whatever it is, pick it up and make it alive from today.

Good morning everyone:
It's a great honor for me to stand here to deliver a speech to you. Then today I want to talk something about dreams and reality.
As the famous Russian litterateur Lev Tolstoy said, “Ideal is the beacon. Without ideal, there is no secure direction; without a direction, there is no life.” So there’s no doubt that everyone needs his or her own ideal. Have you ever thought that what is practical and sensible will connect with our most treasured dreams? Maybe, to somebody, reality has little relation to ideal. To others nothing can be done without the sense of reality. So make our dreams a part of our reality. And make our reality a part of our dreams. There is no reason why our dreams must oppose our reality. Improve our dreams and our reality by bringing them together.
As a student, establishing a dream is one of the most important things we have to do .But everyone must see the reality clearly at first. Your family condition, your personal ability, your social intercourse (交往、交流), your subject and the job you want to do, these things show you the reality and lead you to establish a dream.
Further more, difficult or otherwise, we should put the power of reality into our dreams. Last but not least remember to work hard at the task of chasing 追逐our dreams. Do believe that we can achieve our ideal step by step by the passage of time!
In the end, I want to share with you a poetry named " I think I can".
Maybe you can not understand the meaning of the poetry , But do not be worried ,Let me tell you the meaning.
Thank you for your listening!

Life on earth are the most valuable things money can not buy、jewelry—for—not go back. Life only once、should not renewable and will not re—COME. Students、and your life has just begun blooming flower、you are prosperous home sustenance、development of the Chinese nation are the hope of;your future offspring transmission of both task and maintenance obligations of parents. Therefore、you have to cherish life and take care of life、for themselves and for parents、good for homeland alive.
Life for each person only once、no life、everything is no—go. Therefore、we must firmly embrace the "Yes to life、safety first" awareness of construction safety of our campus so that students can grow up healthily.
Campus safety relates to our lives and learning potential safety problems have as many as 20 kinds、including traffic accidents、poisoning、fire fire、drowning、sports injury and so on. These are at times a threat to the healthy growth of young students. According to statistics、every year our country has around 16、000 unnatural deaths in the primary、elementary and middle school students because of safety accidents、food poisoning、drowning and other deaths、the average has more than 40 people every day、that is to say every day there will be a class of students at "disappeared." So we not only have safety awareness、and more importantly、prevention awareness and preventive measures. Study at daily life、we should note the following:
One、pay attention to safety recess activity. Want the students up and down stairs in an orderly manner and must not hurriedly up and down、up and down the stairs right to cultivate the good habit of walking to prevent accidents on campus crowded stampede. Rainy at our school buildings and office building corridor、staircase、will be very slippery、please the whole Student must light when walking at the foot walk. Everyone should pay attention to civilization recess breaks should not chased noisy.
it is necessary to pay attention to traffic safety. We must strictly comply with rules of the road、without people to ride、not red light running、horse way to go before crosswalks、it is necessary to take the initiative to avoid motor vehicles. Not want to develop the habit of school by bike.
pay attention to food safety. Not to buy "three noes" of food;we should not be at the school gate and street stalls mobile buy snacks、to prevent food poisoning. To learn how to protect themselves、take care of themselves、pay attention not to overeating、try eating less food cold.
it is necessary to pay attention to sports safety. On physical education and extra—curricular activities to prepare before the warming—up、attention should be paid to exercise when not to dramatic collision、so as not to be knocked down or fall.
it is necessary to pay attention to Internet security. Network is a very good learning tool、we can use it to gather information、broaden our horizon. But the network also has a lot of harm、if unhealthy Internet browsing web pages、or indulge in unrestrained virtual space、then it will affect our physical and mental health.
students for their own actions but also have safety awareness. Student encountered at the contradictions between、we want a calm、rational、should not substitute for reasoning with fists、give themselves and their classmates bring about adverse effects. Conflict with the people must bear in mind:the broader picture.
Teacher and fellow students、only one person's life. A collision、a wrestling are probably the lives of vulnerable people's hard to imagine the harm caused. Therefore want to protect their own safety、we comply with the minimum required、the most simple rules and order. Let us bear in mind:human life、safety first!Let us work together to create a harmonious campus、campus safety!
