be 的用法口訣
我用am，你用are，is連著他，她，它;
單數(shù)名詞用is，復(fù)數(shù)名詞全用are。
變疑問，往前提，句末問號莫丟棄。
變否定，更容易，be后not莫忘記。
疑問否定任你變，句首大寫莫遲疑。
be動詞的用法：be (be/is/are/am/was/were)
vi
現(xiàn)在時(shí) I am, you are, he is, we are, you are, they are (縮略式 I'm, you're, he's, we're, you're, they're), (否定縮略式 I'm not, isn't, aren't), 過去時(shí) I was, you were, he was, we were, you were, they were (過去時(shí)否定縮略式 wasn't, weren't), 過去分詞been, 現(xiàn)在分詞being
英語的“be”是個(gè)特殊動詞;有些語言，如馬來文等，并沒有“be”這樣的動詞。
“Be”除了原形的“be”之外，還有另外七種形式：am, is, are, been, being, was, were.
在句子中，“be”可以是主動詞(The Principal Verb)或助動詞(The Auxiliary Verb)
例句對照
【當(dāng)主動詞時(shí)，“be”在性質(zhì)上屬于接系動詞(The Linking Verb), 后面要有名詞、形容詞、地方副詞或短語作補(bǔ)足語(The Complement)。例如：
1. The man is a science teacher.
這個(gè)男子是一位科學(xué)教師
2. Mary's new dresses are colourful.
瑪麗的新衣服色彩鮮艷
3. I have been there before.
我以前去過那里
4. My mother is watching TV in the room.
母親現(xiàn)在在客廳看電視
【這四個(gè)都是陳述句，可以變成疑問句，方法簡單，把主語和“be”或助動詞對換位置即可：
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?
【當(dāng)“be”要在祈使句中出現(xiàn)時(shí)，它必須借重助動詞“do”或“don't”之助，如：
9. Don't be silly!
10. Do be obedient!
11. Don't be a fool!
【“Be”有兩種縮寫法，如下：
12. He's not...../He isn't....
13. You're not...../You aren't...
【但“am + not”的縮寫法只有一個(gè)：
14. I'm not.
有人用“ain't”, 但這并不是標(biāo)準(zhǔn)英語。
談過了“be”作主動詞的功能，現(xiàn)在看看“be”作助動詞時(shí)，有些什么用法：
【1.】“Be + 現(xiàn)在分詞”以組成進(jìn)行式時(shí)態(tài)(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.】“情態(tài)動詞+Be + 過去分詞”以組成被動語態(tài)(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.
