Ⅲ 關於英語情態動詞
情態動詞有can (could), may (might), must, have to, shall (should, will (would), dare (dared), need (needed), ought to等。 情態動詞無人稱和數的變化;不能單獨使用,必須與其後的動詞原形構成謂語
一、 can, could
1) 表示能力(體力、知識、技能)。
Can you lift this heavy box?(體力)
Mary can speak three languages.(知識)
Can you skate?(技能)
此時可用be able to代替。Can只有一般現在時和一般過去式;而be able to則有更多的時態。
I』ll not be able to come this afternoon.
當表示「經過努力才得以做成功某事」時應用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) 表示請求和允許。
-----Can I go now?
----- Yes, you can. / No, you can』t.
此時可與may互換。在疑問句中還可用could,
might代替,不是過去式,只是語氣更委婉,不能用於肯定句和答語中。
---- Could I come to see you tomorrow?
---- Yes, you can. ( No, I』m afraid not. )
3) 表示客觀可能性(客觀原因形成的能力)。
They』ve changed the timetable, so we can go by bus instead.
This hall can hold 500 people at least.
4) 表示推測(驚訝、懷疑、不相信的態度),用於疑問句、否定句和感嘆句中。
Can this be true?
This can』t be done by him.
How can this be true?
二、 may, might
1) 表示請求和允許。might比 may語氣更委婉,而不是過去式。否定回答時可用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...?征徇對方許可時比較正式和客氣,而用Can I...?在口語中更常見。
2)用於祈使句,表示祝願。
May you succeed!
3) 表示推測、可能性(不用於疑問句)。
might不是過去式,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) 表示必須、必要。
You must come in time.
在回答引出的問句時,如果是否定的,不能用mustn』t(禁止,不準),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是說話人的主觀看法, 而have to則強調客觀需要。Must只有一般現在時, have to 有更多的時態形式。
1. he play isn』t interesting, I really must go now.
2. I had to work when I was your age.
3) 表示推測、可能性(只用於肯定的陳述句)
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作情態動詞用時, 常用於疑問句、否定句和條件從句中, 過去式形式為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 作情態動詞用時, 常用於疑問句、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作實義動詞用時, 有人稱、時態和數的變化。在肯定句中,dare後面常接帶to的不定式。在疑問句和否定句中,dare後面可接帶to或不帶to的不定式。而need後面只能接帶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 用於第一人稱,徵求對方的意見。
What shall we do this evening?
2) shall 用於第二、三人稱,表示說話人給對方的命令、警告、允諾或威脅。
1. You shall fail if you don』t work hard.(警告)
2. He shall have the book when I finish it.(允諾)
3. He shall be punished.(威脅)
六、 will, would
1) 表示請求、建議等,would更委婉。
Will / Would you pass me the ball, please?
2) 表示意志、願望和決心。
1. I will never do that again.
2. They asked him if he would go abroad.
3) would表示過去反復發生的動作或某種傾向。would表示過去習慣時比used to正式,且沒有「現已無此習慣」的含義。
1. During the vacation, he would visit me every other day.
2. The wound would not heal.
4) 表示估計和猜想。
It would be about ten o』clock when she left home.
七、 should, ought to
1) should, ought to表示「應該」,ought to表示義務或責任,比should語氣重。
1. I should help her because she is in trouble.
2. You ought to take care of the baby.
2) 表示勸告、建議和命令。should, ought to可通用,但在疑問句中常用should。
1. You should / ought to go to class right away.
2. Should I open the window?
3) 表示推測
should , ought to (客觀推測), must(主觀推測)。
1.He must be home by now. (斷定他已到家)
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、 情態動詞+不定式完成式(have done)
1) can / could + have done在肯定句中表示「本來可以做而實際上能做某事」,是虛擬語氣;在疑問句或否定句中表示對過去行為的懷疑或不肯定, 表示推測。
1. You could have done better, but you didn』t try your best. (虛擬語氣)
2. He can』t have been to that town.(推測)
3. Can he have got the book?(推測)
2) may / might +不定式完成式(have done)
表示對過去行為的推測。不能用於疑問句中,沒有虛擬語氣的用法。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)
用於肯定句中,表示對過去行為的推測。意為「一定、想必」。其疑問、否定形式用can,can』t代替。參看1) can / could + have done表示推測。
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)
用於肯定句中,表示對過去行為的推測。
He should have finished the work by now。
表示「本應該做而實際上沒有做某事」,其否定式表示某種行為本不該發生卻發生了。可以與ought to +不定式完成式(have done)互換。
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「本來不必做而實際上做了某事」。
You needn』t have watered the flowers, for it is going to rain.
6) will +不定式完成式(have done)
主要用於第二、三人稱,表示對已完成的動作或事態的推測。
He will have arrived by now.
Ⅳ 英語關於情態動詞的
情態動詞+have done 是一種虛擬語氣,和情態動詞+動詞原形的區別是:用原型表示事情發生在現在或將來,而用have done ,表示事情發生在過去。
例如,You must be tired now。(你現在一定很累)
You must have seen the film。(你一定看過這部電影)指的是你過去一定看過。
考試常考這么幾種:
must have done (過去)一定做過某事
It must have rained last night。(昨晚一定下雨了)
cann't have done (過去)一定沒有做過某事
He cann't have seen the film,because he doesn's know anying about it。(他一定沒看過那部電影,因為他對它一無所知)
注意:千萬不能用mustn't ,因為它是「禁止,絕不可以」的意思
could have done (過去)本來可以做成某事實際上卻沒有
I could have succeeded in the game if I hadn't have a cold。(如果我沒感冒的話,我可能已經在比賽中成功了)
should have done (過去)應該做某事而沒有做
You should have cleaned your room yesterday。(你昨天就應該把屋子打掃了)而實際上卻沒有
Ⅳ 所有情態動詞(英文+中文)
情態動詞有四類:
①只做情態動詞:must,can(could),may(might),ought to
②可做情態動詞又可做實義動詞:need,dare
③可做情態動詞又可做助動詞:shall(should),will(would)
④具有情態動詞特徵:have(had) to,used to
用法
首先它是動詞,而且不同於行為動詞,行為動詞表示的是可以通過行為來表達的動作(如寫,讀,跑),而情態動詞只是表達的一種想法(如能,也許,敢)。
用法是:情態動詞+行為動詞原形
例句:I can read this sentence in English.
我能用英語讀這句話。
情態動詞是一種本身有一定的詞義,表示說話人的情緒,態度或語氣的動詞,但不能單獨作謂語, 只能和其他動詞原形構成謂語。
We can be there on time tomorrow.我們明天能按時去那兒。
May I have your name? 我能知道你的名字嗎?
Shall we begin now?我們現在就開始嗎?
You must obey the school rules.你必須遵守校規。
情態動詞數量不多,但用途廣泛,主要有下列:
can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would),have (to) ,had better.
Ⅵ 英語中的情態動詞有哪些
1,只做情態動詞:must,can(could),may(might)……
2,可做情態動詞又可做實義動詞:need,dare
3,具有情態動詞特徵:have(had,has) to,used to

Ⅷ 關於英語中的情態動詞
1. have的用法:
have作為行為動詞時,有自己的意思,表示「有」。例如,I have a pen. 否定句就是I don't have a pen. 多借用助動詞do(有時態變化)+not have形式
have 做為助動詞時,用於完成時態,表示已經的狀態。例如,I have done my homework. 否定句是: I haven't done my homework. 直接在have這個助動詞上加not, haven't/hasn't + 動詞完成式
2. need的用法
need作為情態動詞時:need (無任何形態變化) + do sth,否定式needn't + do sth
need作為行為動詞時:need (有時態變化needs/needed) + to do sth, 否定式需用助動詞do來幫忙,don't/didn't/doesn't need to do sth
