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(lèi)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(chēng)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(chēng)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(xiě)形式。概括一下有七種形式：be, am, is, are, was, were, been, being。它們與人稱(chēng)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(xiě)。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?？隙ㄐ问绞且詁e 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.
