單數(shù)名詞用is,復(fù)數(shù)名詞全用are。

變否定,更容易,be后not莫忘記。
疑問(wèn)否定任你變,句首大寫(xiě)莫遲疑。

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(guò)去時(shí) I was, you were, he was, we were, you were, they were (過(guò)去時(shí)否定縮略式 wasn't, weren't), 過(guò)去分詞been, 現(xiàn)在分詞being
英語(yǔ)的“be”是個(gè)特殊動(dòng)詞;有些語(yǔ)言,如馬來(lái)文等,并沒(méi)有“be”這樣的動(dòng)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(dòng)詞(The Principal Verb)或助動(dòng)詞(The Auxiliary Verb)
例句對(duì)照
【當(dāng)主動(dòng)詞時(shí),“be”在性質(zhì)上屬于接系動(dòng)詞(The Linking Verb), 后面要有名詞、形容詞、地方副詞或短語(yǔ)作補(bǔ)足語(yǔ)(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(guò)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(wèn)句,方法簡(jiǎn)單,把主語(yǔ)和“be”或助動(dòng)詞對(duì)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(dòng)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(xiě)法,如下:
12. He's not...../He isn't....
13. You're not...../You aren't...
【但“am + not”的縮寫(xiě)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(yǔ)。
談過(guò)了“be”作主動(dòng)詞的功能,現(xiàn)在看看“be”作助動(dòng)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(dòng)詞+Be + 過(guò)去分詞”以組成被動(dòng)語(yǔ)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.
