回答1:

be一般是用于做表语,而do一般用作谓语,怎么说呢,就是be一般是陈述就是用来说明一件东西咋样咋样,例如,He is handsome,handsome就是表语,而do一般都不会在肯定语气中出现,而只会在否定语气出现,例如,I don't want it,就是用上do的否定形式了,Do有时会用作强调句,He do want to be a friend of mine,这就是用来做强调语气。大概是这样,然后就是except 和besides 这个比较好理解,except 就是除了这个之外没有了,比如说其他人都来了除了小明没来,就用except,Everyone is here except Xiao Ming.而besides就刚好相反,就是班里只有除了小明之外,还有人没来,用besides,Someone is no here besides Xiao Ming.
第3个答的时候应该根据题目来看,题目有不定式,答就要有,题目文的Ought i to,这里用了不定式,所以答的时候也要用不定式。
五楼的那个 I am playing football,这里先说明下,be不是作为动词,play才是动词,而这里是be是表示现在进行时,一种时态,这是be的一个用法,用来表示现在进行时态。

回答5:

先说第一题吧...
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.
