小升初英语核心语法：be动词的用法

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.
