系動(dòng)詞又叫聯(lián)系動(dòng)詞，是聯(lián)系主語(yǔ)和表語(yǔ)的成分，有時(shí)候在句子中的意思不翻譯，有的系動(dòng)詞也有實(shí)際的意義。下面是小編給大家分享的英語(yǔ)系動(dòng)詞用法，大家可以作為學(xué)習(xí)的參考。

1、感官動(dòng)詞

2、狀態(tài)系動(dòng)詞,表主語(yǔ)狀態(tài),只有be

3、持續(xù)性動(dòng)詞,表示主語(yǔ)繼續(xù)或保持一種狀況或態(tài)度

其實(shí)很多系動(dòng)詞可以當(dāng)系動(dòng)詞,也可以當(dāng)實(shí)義動(dòng)詞,但用法有所不同。如:Look

Look at my hand 實(shí)義動(dòng)詞,看

She looks amazing.系動(dòng)詞

初中英語(yǔ)Be動(dòng)詞定義及用法：

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

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.
