在英语中什么时候要用be动词(is,am,are)啊?~

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”是个特别动词;有些语言, “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). 【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. 2. Mary's new dresses are colourful. 3. I have been there before. 4. Mother is in the kitchen now. 【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.】“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.

be是一个连系动词,它有自己不同的形式
现在时:be 进行时:being 过去时:was/were 过去分词:been
它的后面必须跟形容词或名词作表语,与之构成系表结构,充当句子的谓语。
i am a student主语:i 谓语:am a student(系表结构)
being是它的现在进行时态,一般不单独用,而是用于现在进行时的被动语态。(being+动词过去分词)
the bike is being repaired.单车正在被修理中。
it is being finished by him这正在被他完成中。
been是它的过去分词,也不一般单独使用,而是用于现在完成时、过去完成时以及需要它的句子。
i have been here for a long time.我已经到这里有一段时间了。
至于你的问题,这与你想表达的意思有关。
你的工作是什么?
what do you do? what is your job?
那么这里选用do和is有什么根据呢?
第一句里面,第二个do是指你做什么,也就是你的工作,就是一个实义动词。按中文说,what you do已经足够了。可是英语里面就不行,必须跟一个助动词,也就是do.
这里就有了一个结论:当句子中有动词时,我们就用助动词do或是does.如果没有动词时,我们就选用is或是are,也就是b“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).

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.

2. Mary's new dresses are colourful.

3. I have been there before.

4. Mother is in the kitchen now.

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.“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.
当陈述句的谓语是实义动词时,助动词do通常用于疑问句和否定句中。如:

I go to school every day.

我每天上学。

Do you go to school every day?

你每天都上学吗?

I don”t go to school every day.

我不是每天都上学。

另外,助动词do还可用于强调句中,用于强调谓语动词。如:

将助动词do及do 的相应形式放于动词前,而动词要用原形。又如:

I did tell him.

我的确告诉他了。

He does like playing football.

他的确喜欢踢球。
其余时候do作动词原形,表示做.

做“人民”“人们”的时候,只有复数,谓语都是用ARE;做“民族”的时候,与其它普通可数名词一样,单数用IS,复数用are。如:There are 56 peoples in our country.

做人民的时候用IS
做民族的时候用ARE

钮宰卓菲: people意思是人的时候单复同型 是民族的时候可数

吉县15199322553: 英语 peoplepeople是单复同行的,什么时候people做主语后面be动词用is和are.people可以用much修饰吗? -
钮宰卓菲:[答案] people做人们,人民时是集体名词,后面用are,不加s,不能用much修饰 做民族时,是看具体单复数来决定是is还是are,此时复数需加s Good Luck

吉县15199322553: 定语从句先行词为people谓语动词用is还是are -
钮宰卓菲: 这就要看你这个people的含义了1. 表示人,人们的时候就相当于是person的复数形式,后就带are2. 表示人民,民众,大众,就相当于一个集合名词,后带is

吉县15199322553: people前面的be动词用什么 -
钮宰卓菲: people是一个集合名词,就是说它是复数所以用are

吉县15199322553: be用在什么时候用 -

吉县15199322553: people后面的be动词要用单数还是复数?谢谢 -
钮宰卓菲: 多数情况用复数,因为people是单数、复数一样的一个单词.但是还应该看前后的语境.

钮宰卓菲: 可用单 也可用复 看情况 当人的时用复数 当人类时用单数

吉县15199322553: 可数名词复数,be动词用are;不可数名词如people,be动词用什么? -
钮宰卓菲:[答案] 首先,people不是不可数名词 第二,people表示“人”时,一般为集合名词,故通常谓语动词为复数 当然也是可以说几个几个人的,如ten people 牛津例句:At least ten people were killed in the crash.

吉县15199322553: Many people后面be动词要用is还是are.. -
钮宰卓菲: 用are,因为people本身就是复数
