be动词的缩写有哪些

be动词的缩写有哪些

“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.
