反义疑问句与情态动词

发布时间:2013-12-19 16:40:17  

情态动词

一、情态动词的定义:

情态动词表示说话人对某一动作或状态的态度。

※二、情态动词的特点:

1)有一定词义;2)不受主语人称和数的变化影响;3)与主要动词的原形(或称不带to的不定式)一起构成谓语(除ought to作固定词组看待)。

三、情态动词的基本用法:

※(一)、can的用法:

1. (表示能力、功能)能,会

The classroom can seat thirty students. 这教室能坐三十位学生。

June can drive now. 琼现在会开车了。

2. (表示允许、请求)可以

You can't take the book out of the room. 你不可以将这本书拿出室外。

Can I use your pen? 我可以用一下你的笔吗?

3. could的用法

can的过去式;用于婉转语气:能,可以。

◆易混点 can 和 be able to

两者表示能力时用法相同,但can 只有原形 “can” 和过去式“ could ”两种形式,在其他时态中 要用be able to 来表示。 另外 be able to 常常指经过努力, 花费了时间和劳力之后才能做到某事。如: Jim can’t speak English. 吉姆不会说英语。

He could speak English at 5. 他五岁时 就会说英语。

We’ll be able to see him next week.下星期我们将会见到他。

He has been able to drive. 他已经会开车了。

※(二)、may的用法

1. 表示请求和允许,意思是:可以

He may come if he likes. 如果他想来,可以来。

◆ 易混点 can和may

can 和 may 均可用来征求意见或许可,意为“可以”, 一般可互换使用。如:

Can/ May I help you ? 我能帮助你吗?

2. 表示祝愿,意思是:祝…,(但愿)。

May you have a good luck! 祝你好运。

3. 表示推测,意思是:可能(会),或许(会)。

It may rain this evening. You'd better take an umbrella.

◆易混点may be 和maybe

用法区别 常用位置

may be may为情态动词, be为动词原形 句中,作谓语

maybe 副词,大概、也许,相当于perhaps 句首,作状语

He may be wrong , but I’m not sure. 也许他错了,但我也不确定。

4. might的用法: may的过去式;用于婉转语气:能,可以

(三)、must的用法

※1.表“必须”。

You must talk to them about their study.你必须同他们谈谈关于他们学习的事。

◆易混点must 和 have to

1). must 侧重于个人意志和主观上的必要,还可以在间接引语中表示过去的必要或业务。

2). have to 侧重于客观上的必要,可用于现在时、过去时和将来时。如:

I know I must study hard. 我知道我必须努力学习。

My brother was very ill, so I had to call the doctor in the midnight.

我弟弟病得厉害, 我只得半夜里把医生请来。

注意have to/ had to/has to

否定句用 don’t/ doesn’t / didn’t +have to + 动词原形

疑问句用 Does/Do/Did + 主语 + have to + 动词原形

2. 在否定结构中表“禁止,不许”。

You mustn't leave here.你不能离开这儿。

★3. 表推测,暗含有很大的可能性,用在肯定句。

He must be ill. He looks so pale.他肯定是病了。他的脸色那么苍白。

注意:

1) 在肯定句中用 might,may,must,不用can。may 暗含的可能性较小。might表示的可能性太小,

没有足够的说服力去职责别人。must 暗含的可能性较大。

2) 在疑问句中表示推测用 can,不用 might, may,must

3) 在否定句中用can’t(不可能), 不用 may, must。

The baby can't be ill. He is so active.那宝宝不大可能是病了。他那么活跃。

四、would的用法

※1. would是will的过去式,Would you like…?表示请求、劝说,是很客气的说法。

Would you like a cup of tea?您愿意喝杯茶吗?

2. 主语+would like to…表示“想要…”的意思上,与want to…意思一 样,但用此句型较客气。I want to ask you a question. =

五.ought to\ should的用法

ought to 是一个可以加上to 的情态动词其意思与should是一样的, 大多数情况下二者可以互换,但是should谈的是自己的主观看法,ought to则更多反映客观情况,在谈到法律、义务和规定时使用。 如: We should/ought to help each other and learn from each other in our work.

She is your mother, so you ought to support her.

We ought to go and see Mary tomorrow, but I don’t think we will.

★六、need的用法

need “需要”,可作情态动词,特点1)不受主语人称、数和时态的变化影响;2)后面接动词原形;3)否定形式在后面接not

也可作实义动词,特点1)有时态,人称数的变化;2)后面接to do;3)否定形式要用助动词,doesn’t\ don’t\ didn’t need to do sth.

情态动词can, may, must, ought to, had better等在句中直接加动词原形, 叫做纯情态动词。 have to, need, dare等既可做情态动词, 又可做实义动词, 成为半情态动词。

need的用法

1. need做情态动词的用法

当need做情态动词时, 用法与其他情态动词一致, 后面必须接V原, 没有人称和数的变化, 否定 needn’t, 疑问句直接把need提前。

(1) need “需要”“必须” 通常用于否定句, 疑问句或条件句

eg: You needn’t do that again.

▲(2) 一般疑问句的答语。 肯定用must, 否定用needn’t

eg: ----Need I go with her?

----Yes, you must. /No, you needn’t.

【must 必须,mustn’t 表禁止 ---Must…? ---Yes, …must/No,…needn’t/don’t have to】

2. need做实义动词的用法

当need做实义动词时, 有人称与数的变化,变否定疑问需要助动词帮忙。

(1) need+名词

eg: She needs money.

(2) sb+ need + to do sth “某人需要去做某事”

eg: She needs to finish her homework.

否: She doesn’t need to finish her homework.

疑: ----Does she need to finish her homework?

----Yes, she does. /No, she doesn’t.

▲★ (3) sth + need + doing “某物需要被做”=sth + need + to do done.

eg: This bike needs repairing. =This bike needs to be repaired.

3. need还可做名词。eg: There’s no need for you to try again.

七. have to的用法

1. ★have to 与情态动词must的区别: 两者都有“必须”之意, 但是have to 侧重于强调客观条件

需要做的事情, must侧重于表示说话人的主观看法, 认为有义务, 有必要做某事。

eg: I must finish my homework first.

The room is so dirty, I have to clean it.

2. have to 有人称变化, 其他情态动词没有。have to 有多种时态变化,can,may等只有过去式。

eg: She has to work on the farm all day.

He can swim in the river. I could swim when I was young.

3. ★▲have to 不能直接用来否定和提问, 需要用助动词do/does/did等帮助。 而其他情态动词一般

都可以直接进行否定和提问。

eg: Does she have to work on the far all day?/She doesn’t have to work all day.

Can he swim in the river. /He can’t swim in the river.

一.常用can/could句式:

1. This work is I can do.这个工作超出我所能做的。

2. He had run away 我还没来得及谢他,他已经跑了

3. You cannot be careful. 你越仔细越好

4. You can’t pay attention to your spelling.你越注意你的拼写越好

? was able to do表过去成功地做了某事 = managed to do=succeeded in doing

? can’t wait to do 等不及要做

易混点 can 和 be able to

两者表示能力时用法相同,但can 只有原形 “can” 和过去式“ could ”两种形式,在其他时态中 要用be able to 来表示。 另外 be able to 常常指经过努力, 花费了时间和劳力之后才能做到某事。如: Jim can’t speak English. 吉姆不会说英语。

He could speak English at 5. 他五岁时 就会说英语。

We’ll be able to see him next week.下星期我们将会见到他。

He has been able to drive. 他已经会开车了。

2. Why you make so much noise?偏偏

3. He live near here, doesn’t he?一定

4. You shout in class.禁止,不可以

5.It Mr.li, isn’t/is it? 一定是 8.He must have arrived here by air yesterday, didn’t he?

9.You must have learned French before, haven’t you?

陈述句含有情态动词must有两种情况:

1、must表示“必须”,反意疑问句部分为mustn’t…? / needn’t…?

He must study hard at English, mustn’t he? / needn’t he?

You must go home now, needn’t you? / mustn’t you?

We mustn’t be late, must we ?

2、must表示推测:“一定,肯定” 反意疑问句部分与must后面的动词呼应

You must be joking, aren’t you?

He must be ill, isn’t he ?

3、注意:用must对过去的动作推测时,反意疑问句部分的助动词用did或have, 而对过去的状态推测,反意疑问句部分的be动词用was:

1. 选B,should 后接动词完成式表示“本来应该做某事,结果未做”,此处含有责备之意。

2. 选B,对过去情况的肯定推测,宜用“情态动词 + 动词完成式”,再根据句意,可确定答案为B。注:can 表示推测通常不用于肯定陈述句。

3. 选B,表示过去可能发生而实际上未发生的事,用might + 动词完成式。若只是推测过去可能已经发生的事,则可用 may [might] + 动词完成式,如 He may [might] have gone. 他可能已经走了。

4. 选C。由句意可知。

5. 选B,do all one can 意为“尽力”或“竭尽全力”。

7

追求梦想 克服困境 从迷茫中寻找方向 人生终将成功

6. 选C,mustn’t 在此相当于 can’t,且语气更强。

7. 选B,“needn’t + 动词完成式”的意思是:本来不必做某事,但实际上做了。上句意思是“你本来不必告诉他这个消息的,因为他(当时)已经知道了”。注意,句中 knew 为过去式。

8. 选B,must 后接动词完成式表示对过去情况的肯定推测,意为“一定已经做了某事”。

9. 选B,should 后接动词完成式表示“本来应该做某事,结果未做”。

10. 选B,对过去情况的肯定推测,宜用“情态动词 + 动词完成式”,再根据句意,可确定答案为B。注:can 表示推测通常不用于肯定句。

12. 选A。may have done sth 表示对过去可能发生的事进行推测,意为“可能曾经”。

13. 选C。根据上下文的语境推知。can’t 意为“不能”。

14. 选B。根据上下文的语境推知。can’t 表推测,意为“不不能”

15. 选D。couldn’t have done sth 表示对过去情况进行推测,意为“过去不可能发生过某情况”。

17. 选A。根据下文的 will be 可知,“他考试再不及格”是将来的事,据此可排除B和D。再根据语意,排除C。

18. 选D。从时间上看,由于是昨天没来开会,所以推测他生病也应指昨天,故排除A和C。从语境上看,既然上文说 I’m not so sure,那么说明说话者对自己的推测没有很大把握,故选D。

19. 选C。根据上文的过去时态可知,此句谈的是过去的事,故排除A和C。根据语境排除D。

20. 选C。couldn’t have done sth 结构在此表示责备,指过去本来可以做某事但实际上未做。第二空填 was wasted,陈述的是过去的一事实。

21. 选B。根据下文的 I’ll phone the airport and find it out 可知,说话人对自己的推测没有很大把握,故选 might。若选A,语气太强,不合语境;若选D,不合语法习惯,因为can 表推测通常不用于肯定陈述句中。

22. 选D。既然“通行证现在不在口袋里”,那么它“掉出去”应发生在过去,故排除A和B。比较选项C和D所表示的意思,选D更恰当。

24. 选A。根据 Don’t be so sure 可知前面一空应填must。第二空填的could表示推测,虽为过去式形式,但表示现在意义,语气较委婉,它与表推测的 can 主要用于否定句和疑问句不同,它可以用于肯定陈述句。

25. 选A。根据句中有关时态可知“他来”发生在过去,故排除B;根据 I don’t know 可知选项C语气太肯定,不合适;选项D的意思是“本来应该来”,与语境不合。

A.He must be an engineer,isn’t he?They must be writing now,aren’t they?(这类句子问句前部分含“must be?”或“must be doing?”。)

B.She must have a car/live there, doesn’t she?

C.He must have seen the film,hasn’t he?(这类句子问句前部分的谓语为must have done,句子无具体过去时间状语。)

例如:She may have finished her homework,hasn’t she?

五、几组词语辨析

1.must与have to:must强调说话者的主观看法,have to强调客观需要,表示“不必”意要用needn’t或don’t/didn’t/won’t have to,不能用mustn’t。

2.can/could与be able to:can多用于现在时,也可用于将来时,could只用于过去时,be able to可用于各种时态。表示“过去经过努力而做成(或没做成)”要用was/were(not) able to ,而不用could(not)。例如:He worked hard,but he wasn’t able to pass the exam.
