be动词用法

“Be”除了原形的“be”之外,还有另外七种形式:am is are been being was were.

在句子中,“be”可以是主动词(The Principal Verb)或助动词(The Auxiliary Verb).

当主动词时,“be”在性质上属于接系动词(The Linking Verb) 后面要有名词、形容词、地方副词或短语作补足语(The Complement)。例如:

1. The man is a science teacher.

2. Mary's new dresses are colourful.

3. I have been there before.

4. Mother is in the kitchen now.

这四个都是陈述句,可以变成疑问句,方法简单,把主语和“be”或助动词对换位置即可:

5. Is the man a science teacher?

6. Are Mary's new dresses colourful?

7. Have I been there before?

8. Is mother in the kitchen now?

当“be”要在祈使句中出现时,它必须借重助动词“do”或“don't”之助,如:

9. Don't be silly!

10. Do be obedient!

11. Don't be a fool!

“Be”有两种缩写法,如下:

He's not...../He isn't....

You're not...../You aren't...

但“am not”的缩写法只有一个:

I'm not.

谈过了“be”作主动词的功能,现在看看“be”作助动词时,有些什么用法:

1.“Be 现在分词”以组成进行式时态(Continuous Tenses),如:

Tony's maid is washing his new car.

The children are playing in the field.

Samuel was eating when I came in.

We have been living here since 1959.

2.“Be 过去分词”以组成被动语态(The Passive Voice) 如:

Her money in the drawer was stolen.

A number of good jobs are taken up byforeigners.

David studied in Taiwan but has been trained as a language lecturer in America.

Can all the wonderful birds be found in our Bird Park?

The disobedient boy was told to stand out- side the classroom.

Steps are being taken to reduce traffic con- gestion during peak hours.

Dishonest students will be immediately dealt with.

2找不到系动词再找情态动词:can may must will shall need could should would might 找到后变人称(第一人称变第二人称,第三人称不变)加问号。例:They will go to school.变Will they go to school?

3找have got has got had got.找到后把have has had 提前,got留在原地不动。变人称加问号 例:You have got a TV.变Have you got a TV?

4添加助动词:do does did 把助动词加在最前面 ,例:I play with a dog变Do you play with a dog.以上四种方法变成疑问句之后把里面的动词都变成原型。
