Be有两种形式
第一,系动词,所构成的句子结构为主系表,表现形式有:is, am, are, was, were,在句子中翻译为“是”
如:
I am a girl. 我是个女孩。
第二,助动词,无实际意义,与其他动词一起构成时态。表现形式有:is, am, are, was, were以及Be原形。
如:
I am reading. 我正在看书。(进行时)
be动词的用法
be
[bi:]
vi
现在时 I am, you are, he is, we are, you are, they 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 was, we were, you were, they were (过去时否定缩略式 wasn't, weren't), 过去分词 been, 现在分词 being
英语的“be”是个特别动词;有些语言,如中文和马来文,并没有“be”这样的动词。
“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:
12. He's not...../He isn't....
13. You're not...../You aren't...
【但“am + not”的缩写法只有一个:
14. I'm not.
有人用“ain't”, 但这并不是标准英语。
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:
15. Tony's maid is washing his new car.
16. The children are playing in the field.
17. Samuel was eating when I came in.
18. We have been living here since 1959.
【2.】“Be + 过去分词”以组成被动语态(The Passive Voice),如:
19. Her money in the drawer was stolen.
20. A number of good jobs are taken up byforeigners.
21. David studied in Taiwan but has been trained as a language lecturer in America.
22. Can all the wonderful birds be found in our Bird Park?
23. The disobedient boy was told to stand out- side the classroom.
24. Steps are being taken to reduce traffic con- gestion during peak hours.
25. Dishonest students will be immediately dealt with.
