be動(dòng)詞的用法整理

時(shí)間: 維維20 分享

學(xué)習(xí)英語(yǔ)的時(shí)候,很多人都是比較苦惱語(yǔ)法的學(xué)習(xí),就如be動(dòng)詞的用法就很多,下面給大家分享一些關(guān)于be動(dòng)詞的用法整理,希望對(duì)大家有所幫助。

be動(dòng)詞的用法篇一

1. Be動(dòng)詞有三個(gè),am,is還有are.我用am, 你用are, is跟著他她它,復(fù)數(shù)全部都用are.

如果遇到過(guò)去時(shí),was來(lái)把a(bǔ)m,is替,were來(lái)把換掉動(dòng)詞are

2. do和be動(dòng)詞的用法區(qū)別

Be 動(dòng)詞就是(am,are,is)..句子中如果沒(méi)有實(shí)意動(dòng)詞(例如:write,buy)之類的動(dòng)詞,就直接在主語(yǔ)后面加Be動(dòng)詞。而如果是句子中有實(shí)意動(dòng)詞,那么如果你要改為一般疑問(wèn)句,就要借助DO(do也稱為助動(dòng)詞),例如:I study.

改為一般疑問(wèn)句:Do you study ?

順口溜:be氏三朵花, am, is還有are,

我(I)戀am, 你(you)戀are,

is跟了他(he)她(she)它(it),

單娶is, 復(fù)娶are。

be動(dòng)詞的用法篇二

英語(yǔ)的be 動(dòng)詞是個(gè)用法比較復(fù)雜的動(dòng)詞。復(fù)雜的原因有兩點(diǎn):

1、 除了原形的 be 之外,對(duì)于不同人稱代詞以及單數(shù)名詞和復(fù)數(shù)名詞,be 會(huì)有各種變化形式和縮寫形式。概括一下有七種形式:be, am, is, are, was, were, been, being。它們與人稱代詞和名詞單、復(fù)數(shù)的搭配關(guān)系是:

現(xiàn)在時(shí) I am, you are, he/she/it/ is, we/you/they are;名詞單數(shù)、不可數(shù)名詞用is,復(fù)數(shù)用are。

縮略式 I'm, you're, he's, we're, you're, they're

否定縮略式 I'm not, isn't, aren't

過(guò)去時(shí) I was, you were, he/she/it/ was, we/you/they were;名詞單數(shù)、不可數(shù)名詞用was,復(fù)數(shù)用were。

否定縮略式 wasn't, weren't

過(guò)去分詞 been

現(xiàn)在分詞 being

2、在句子中,be有兩種主要作用:一是作為系動(dòng)詞(The Linking Verb),本身可以作用謂語(yǔ)動(dòng)詞;二是做為助動(dòng)詞(The Auxiliary Verb),與謂語(yǔ)動(dòng)詞一起構(gòu)成各種時(shí)態(tài)和被動(dòng)語(yǔ)態(tài)等。

下面做個(gè)簡(jiǎn)要的講解。

be動(dòng)詞的用法:做系動(dòng)詞

1、系動(dòng)詞+表語(yǔ)”的結(jié)構(gòu)

當(dāng)be 動(dòng)詞做系動(dòng)詞使用時(shí),主要構(gòu)成“系動(dòng)詞+表語(yǔ)”的結(jié)構(gòu),在句子中做謂語(yǔ)。表語(yǔ)可以是名詞、形容詞、副詞、介詞短語(yǔ)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 動(dòng)詞的一般疑問(wèn)句,方法是把be 移到主語(yǔ)前面,也可說(shuō)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 動(dòng)詞用在特殊疑問(wèn)句

在特殊疑問(wèn)句里,be 動(dòng)詞仍然移到主語(yǔ)前面,但特殊疑問(wèn)句是以特殊疑問(wèn)詞開(kāi)頭的,所以be 動(dòng)詞只能說(shuō)是移到主語(yǔ)前面,或者說(shuō)是在特殊疑問(wèn)詞的后面。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 動(dòng)詞的否定句

be 動(dòng)詞做謂語(yǔ)時(shí),它的否定形式是在be 后加not,并且可以縮寫。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 動(dòng)詞的祈使句

be 動(dòng)詞的祈使句有肯定和否定兩種形式。肯定形式是以be 動(dòng)詞開(kāi)頭,而否定形式或強(qiáng)調(diào)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.
