Ⅲ 关于英语情态动词

情态动词有can (could), may (might), must, have to, shall (should, will (would), dare (dared), need (needed), ought to等。 情态动词无人称和数的变化;不能单独使用,必须与其后的动词原形构成谓语

一、 can, could

1) 表示能力(体力、知识、技能)。

Can you lift this heavy box?(体力)

Mary can speak three languages.(知识)

Can you skate?(技能)

此时可用be able to代替。Can只有一般现在时和一般过去式;而be able to则有更多的时态。

I’ll not be able to come this afternoon.

当表示“经过努力才得以做成功某事”时应用be able to,不能用Can。如:

He was able to go to the party yesterday evening in spite of the heavy rain.

2) 表示请求和允许。

-----Can I go now?

----- Yes, you can. / No, you can’t.

此时可与may互换。在疑问句中还可用could,

might代替,不是过去式,只是语气更委婉,不能用于肯定句和答语中。

---- Could I come to see you tomorrow?

---- Yes, you can. ( No, I’m afraid not. )

3) 表示客观可能性(客观原因形成的能力)。

They’ve changed the timetable, so we can go by bus instead.

This hall can hold 500 people at least.

4) 表示推测(惊讶、怀疑、不相信的态度),用于疑问句、否定句和感叹句中。

Can this be true?

This can’t be done by him.

How can this be true?

二、 may, might

1) 表示请求和允许。might比 may语气更委婉,而不是过去式。否定回答时可用can’t

或mustn’t,表示“不可以,禁止”。

----Might/ May I smoke in this room?

---- No, you mustn’t.

---- May/Might I take this book out of the room?

---- Yes, you can. (No, you can’t / mustn’t. )

用May I...?征徇对方许可时比较正式和客气,而用Can I...?在口语中更常见。

2)用于祈使句,表示祝愿。

May you succeed!

3) 表示推测、可能性(不用于疑问句)。

might不是过去式,它所表示的可能性比may小。

1.He may /might be very busy now.

2.Your mother may /might not know the truth.

三、 must, have to

1) 表示必须、必要。

You must come in time.

在回答引出的问句时,如果是否定的,不能用mustn’t(禁止,不准),而用needn’t, don’t have to(不必).

---- Must we hand in our exercise books today?

---- Yes, you must.

---- No, you don’t have to / you needn’t.

2) must是说话人的主观看法, 而have to则强调客观需要。Must只有一般现在时, have to 有更多的时态形式。

1. he play isn’t interesting, I really must go now.

2. I had to work when I was your age.

3) 表示推测、可能性(只用于肯定的陈述句)

1. You’re Tom’s good friend, so you must know what he likes best.

2. Your mother must be waiting for you now.

四、 dare, need

1) dare作情态动词用时, 常用于疑问句、否定句和条件从句中, 过去式形式为dared。

1. How dare you say I’m unfair?

2. He daren’t speak English before such a crowd, dare he?

3. If we dared not go there that day, we couldn’t get the beautiful flowers.

2) need 作情态动词用时, 常用于疑问句、否定句。在肯定句中一般用must, have to, ought to, should代替。

1.You needn’t come so early.

2. ---- Need I finish the work today?

---- Yes, you must. / No, you needn’t.

3) dare和 need作实义动词用时, 有人称、时态和数的变化。在肯定句中,dare后面常接带to的不定式。在疑问句和否定句中,dare后面可接带to或不带to的不定式。而need后面只能接带to的不定式。

1. I dare to swim across this river.

2. He doesn’t dare (to) answer.

3. He needs to finish his homework today.

五、 shall, should

1) shall 用于第一人称,征求对方的意见。

What shall we do this evening?

2) shall 用于第二、三人称,表示说话人给对方的命令、警告、允诺或威胁。

1. You shall fail if you don’t work hard.(警告)

2. He shall have the book when I finish it.(允诺)

3. He shall be punished.(威胁)

六、 will, would

1) 表示请求、建议等,would更委婉。

Will / Would you pass me the ball, please?

2) 表示意志、愿望和决心。

1. I will never do that again.

2. They asked him if he would go abroad.

3) would表示过去反复发生的动作或某种倾向。would表示过去习惯时比used to正式,且没有“现已无此习惯”的含义。

1. During the vacation, he would visit me every other day.

2. The wound would not heal.

4) 表示估计和猜想。

It would be about ten o’clock when she left home.

七、 should, ought to

1) should, ought to表示“应该”,ought to表示义务或责任,比should语气重。

1. I should help her because she is in trouble.

2. You ought to take care of the baby.

2) 表示劝告、建议和命令。should, ought to可通用,但在疑问句中常用should。

1. You should / ought to go to class right away.

2. Should I open the window?

3) 表示推测

should , ought to (客观推测), must(主观推测)。

1.He must be home by now. (断定他已到家)

2.He ought to/should be home by now.(不太肯定)

3. This is where the oil must be.(直爽)

4. This is where the oil ought to/should be.(含蓄)

八、 情态动词+不定式完成式(have done)

1) can / could + have done在肯定句中表示“本来可以做而实际上能做某事”,是虚拟语气;在疑问句或否定句中表示对过去行为的怀疑或不肯定, 表示推测。

1. You could have done better, but you didn’t try your best. (虚拟语气)

2. He can’t have been to that town.(推测)

3. Can he have got the book?(推测)

2) may / might +不定式完成式(have done)

表示对过去行为的推测。不能用于疑问句中,没有虚拟语气的用法。Might所表示的可能性比may小。

1. He may not have finished the work .

2. If we had taken the other road, we might have arrived earlier.

3)must +不定式完成式(have done)

用于肯定句中,表示对过去行为的推测。意为“一定、想必”。其疑问、否定形式用can,can’t代替。参看1) can / could + have done表示推测。

1. You must have seen the film Titanic.

2. He must have been to Shanghai.

4)should +不定式完成式(have done)

用于肯定句中,表示对过去行为的推测。

He should have finished the work by now。

表示“本应该做而实际上没有做某事”,其否定式表示某种行为本不该发生却发生了。可以与ought to +不定式完成式(have done)互换。

1. You ought to / should have helped him. (but you didn’t.)

2. She shouldn’t have taken away my measuring tape, for I wanted to use it.

5) needn’t +不定式完成式(have done)

表示“本来不必做而实际上做了某事”。

You needn’t have watered the flowers, for it is going to rain.

6) will +不定式完成式(have done)

主要用于第二、三人称,表示对已完成的动作或事态的推测。

He will have arrived by now.

Ⅳ 英语关于情态动词的

情态动词+have done 是一种虚拟语气,和情态动词+动词原形的区别是:用原型表示事情发生在现在或将来,而用have done ,表示事情发生在过去。
例如,You must be tired now。(你现在一定很累)
You must have seen the film。(你一定看过这部电影)指的是你过去一定看过。
考试常考这么几种:
must have done (过去)一定做过某事
It must have rained last night。(昨晚一定下雨了)
cann't have done (过去)一定没有做过某事
He cann't have seen the film,because he doesn's know anying about it。(他一定没看过那部电影,因为他对它一无所知)
注意:千万不能用mustn't ,因为它是“禁止,绝不可以”的意思
could have done (过去)本来可以做成某事实际上却没有
I could have succeeded in the game if I hadn't have a cold。(如果我没感冒的话,我可能已经在比赛中成功了)
should have done (过去)应该做某事而没有做
You should have cleaned your room yesterday。(你昨天就应该把屋子打扫了)而实际上却没有

Ⅳ 所有情态动词(英文+中文)

情态动词有四类:
①只做情态动词:must,can(could),may(might),ought to
②可做情态动词又可做实义动词:need,dare
③可做情态动词又可做助动词:shall(should),will(would)
④具有情态动词特征:have(had) to,used to

用法
首先它是动词,而且不同于行为动词,行为动词表示的是可以通过行为来表达的动作(如写,读,跑),而情态动词只是表达的一种想法(如能,也许,敢)。
用法是:情态动词+行为动词原形
例句:I can read this sentence in English.
我能用英语读这句话。
情态动词是一种本身有一定的词义,表示说话人的情绪,态度或语气的动词,但不能单独作谓语, 只能和其他动词原形构成谓语。
We can be there on time tomorrow.我们明天能按时去那儿。
May I have your name? 我能知道你的名字吗?
Shall we begin now?我们现在就开始吗?
You must obey the school rules.你必须遵守校规。
情态动词数量不多,但用途广泛,主要有下列:
can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would),have (to) ,had better.

have 做为助动词时,用于完成时态,表示已经的状态。例如,I have done my homework. 否定句是: I haven't done my homework. 直接在have这个助动词上加not, haven't/hasn't + 动词完成式
2. need的用法
need作为情态动词时:need (无任何形态变化) + do sth,否定式needn't + do sth
need作为行为动词时:need (有时态变化needs/needed) + to do sth, 否定式需用助动词do来帮忙,don't/didn't/doesn't need to do sth
