be动词的用法口诀

be的用法口诀
 
  我用am,你用are,is连着他,她,它;
 
  单数名词用is,复数名词全用are。
 
  变疑问,往前提,句末问号莫丢弃。
 
  变否定,更容易,be后not莫忘记。
 
  疑问否定任你变,句首大写莫迟疑。
 
  be动词的用法:be (be/is/are/am/was/were)
 
  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”是个特殊动词;有些语言,如马来文等,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)。
 
  例句对照
 
  【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.
