不当谓语

动词"be"的用法

-----------------------------------------------

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.

从上面例子看,“be”这动词外貌平凡,但内涵丰厚。如果没有“be”,补足语的桥梁断了。如果没有“be”,何来进行式时态和被动语态?缺了这几样重要的句式,英语还像英语吗?
