【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. 这个男子是一位科学教师 2. Mary's new dresses are colourful. 玛丽的新衣服色彩鲜艳 3. I have been there before. 我以前去过那里 4. My mother is watching TV in the room. 母亲现在在客厅看电视 【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.】“情态动词+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.
