《be动词的用法整理》
学习英语的时候,很多人都是比较苦恼语法的学习,就如be动词的用法就很多,下面给大家分享一些关于be动词的用法整理,希望对大家有所帮助。
be动词的用法篇一
1. Be动词有三个,am,is还有are.我用am, 你用are, is跟着他她它,复数全部都用are.
如果遇到过去时,was来把am,is替,were来把换掉动词are
2. do和be动词的用法区别
Be动词就是(am,are,is)..句子中如果没有实意动词(例如:write,buy)之类的动词,就直接在主语后面加Be动词。而如果是句子中有实意动词,那么如果你要改为一般疑问句,就要借助DO(do也称为助动词),例如:Istudy.
改为一般疑问句:Do you study ?
顺口溜:be氏三朵花, am, is还有are,
我(I)恋am, 你(you)恋are,
is跟了他(he)她(she)它(it),
单娶is, 复娶are。
be动词的用法篇二
英语的be 动词是个用法比较复杂的动词。复杂的原因有两点:
1、 除了原形的 be 之外,对于不同人称代词以及单数名词和复数名词,be 会有各种变化形式和缩写形式。概括一下有七种形式:be, am, is,are, was, were, been, being。它们与人称代词和名词单、复数的搭配关系是:
现在时 I am, you are, he/she/it/ is, we/you/they are;名词单数、不可数名词用is,复数用are。
缩略式 I'm, you're, he's, we're, you're, they're
否定缩略式 I'm not, isn't, aren't
过去时 I was, you were, he/she/it/ was, we/you/theywere;名词单数、不可数名词用was,复数用were。
否定缩略式 wasn't, weren't
过去分词 been
现在分词 being
2、在句子中,be有两种主要作用:一是作为系动词(The Linking Verb),本身可以作用谓语动词;二是做为助动词(The AuxiliaryVerb),与谓语动词一起构成各种时态和被动语态等。
下面做个简要的讲解。
be动词的用法:做系动词
1、系动词+表语”的结构
当be 动词做系动词使用时,主要构成“系动词+表语”的结构,在句子中做谓语。表语可以是名词、形容词、副词、介词短语等。例如:
The man is a science teacher.
Mary's new dresses are colourful.
Mother is in the kitchen now.
I have been there before.
They shall be here at 10:00 tommorow.
That can't be true.
You are not being very polite.
Your brother is being very annoying this evening
2、be 动词的一般疑问句,方法是把be 移到主语前面,也可说成是移到句首。
Is the man a science teacher? Yes, he is. / No, he isn't.
Are Mary's new dresses colourful? Yes, they are. / No, they aren't.
Was mother in the kitchen then? Yes, she was. / No, she wasn't.
Were you at home the day before yesterday? Yes, I was. / No, I wasn't.
Was she late this morning? Yes, she was. / No, she wasn't.
3、be 动词用在特殊疑问句
在特殊疑问句里,be 动词仍然移到主语前面,但特殊疑问句是以特殊疑问词开头的,所以be动词只能说是移到主语前面,或者说是在特殊疑问词的后面。例如:
Whose bike is broken? Xiao Ming's bike is.
Who was singing in the room? Mr. Zhang was.
Where are you from? I am from Wuhu.
What class were you in? We were in Class 2.
How old is Tom? He is ten.
4、be 动词的否定句
be 动词做谓语时,它的否定形式是在be 后加not,并且可以缩写。例如:
It is not sunny today.
Tom and his friends are not in the park.
You were not nine years old when I went to the university.
He was not often late for his class when he was a student.
I wasn't here yesterday.
My parents weren't at home last Sunday.
5、be 动词的祈使句
be 动词的祈使句有肯定和否定两种形式。肯定形式是以be 动词开头,而否定形式或强调句形,要加don't 或do。例如:
Be careful!
Be a good boy!
Don't be silly!
Don't be a fool!
Do be obedient!
Do be careful.
