高考英语《情态动词》专项练习(含答案)第一节交际1.表示“请求”,请别人做事。
用will, would, can , could。
句型:1)Will / Would you(please)do …?(2)Can / Could you do … ?在这两个句型中would, could比will, can更正式、客气。
Will / Would you please explain the text once again ?Can / Could you tell me what time Flight 312 arrives?2.询问是否“许可”。
用can / could,may / might句型:(1)May / Might I do … ? (2)Can / Could I do…?在这两个句型中could, might比can, may更正式、客气。
— Could I use your car ?— Yes, of course, you can ?(回答必须用can)— Might I have a look at your new computer ?— Yes, you may(回答必须用may)或Please go ahead.3.自己想做,要求对方做决定, 即征询对方意见。
用shall,用于第一人称和第三人称。
句型:Shall I(we, he, she it, they)…?译“要不要…?”— The room is so dirty. Shall we clean it?— Of course. (03全国春季)Shall these goods be sent over to you at once ? 要不要把这些货物马上送给你?4.表示规劝,建议1)正面的规劝,表示“最好”,“应该”,或“必须”做某事。
①表示“最好”,用had better,may / might as well或It is better / best to do sth.You might just as well tell the manufacturer that male customers may not like the design of the furniture.If you are planning to spend your money having fun this week, betterforget it—you’ve got some big bills coming.(04广东卷)(better forget it相当于You had better forget it.)②表示“有义务或有必要”,用should或ought to。
即“应该”。
If you see anything unusual, you should call the police.③用must 译:“必须”。
The guide required that all passengers must wear seat belts.导游要求所有旅客必须系安全带。
2)反面的规劝,表示“不必”,“不应当”,或“不许”做某事。
①表示“不必”,用needn’t 或don’t have to 。
--- I don't mind telling you what I know.--- You needn’t. I'm not asking you for it. (04江苏卷)Y ou needn’t return / don’t have to return the book now. You can keep it till next week.②表示“不应该”,用shouldn’t或oughtn’t to。
W e shouldn’t throw cold water on them. 我们不应当给他们泼冷水。
③表示“不许”,用mustn’t。
You mustn’t smoke in cl ass. 上课时不准吸烟。
needn’t / don’t have to →shouldn’t →mustn’t 语气逐步加强5.须区别或注意的情态动词1)can, could与be able to的区别a)表示能力时can和be able to可以互换使用I can / am able to speak English. She could / was able to read novels at ten.b)表示在过去某一特定场合下,一次性表现出来的能力,只能用was / were able to。
The fire spread through the hotel very quickly but everyone get out.A.had to B.would C.could D.was able to(答案D)2)shall用在主语是第二、第三人称的陈述句中,表示说话人给对方的许诺或命令。
Work hard and you shall be paid. 好好干,你会得到报酬的。
(许诺)You shall leave here at once. = You must leave here at once. (命令)shall也用于法律、法令或规章等正式文件中,表示义务或规定。
译“应,必须”。
The fine shall be paid in cash. 罚款应以现金交纳。
3)need和dare的用法。
改错:1)To become a member of this club, one need attend three meeting and pay his fees regularly.2)We do need masses of young people who dare accept all kinds of challenges.a)need(需要),dare(敢于)可作行为动词用,句型need to do, dare to do。
也可作情态动词,但不能用在肯定句。
在肯定句中只能作行为动词使用,故第一题B错,need → needs to;第二题C错,accept → to acceptb)need,作情态动词用时,无人称变化。
need用于否定句和疑问句中;dare 用于否定句、疑问句和条件句中。
Y ou needn’t work so hard. →You don’t need to work so hard.— Need I go at once.—Yes, you must. / No, you needn’t.Mary dare not touch the snake. →Mary doesn’t dare(to)touch the snake.Dare you walk through the forest at night ?If the enemy dare enter our country, we will fight against them to the end.如果敌人胆敢进入我国,我们就和他们战斗到底。
4)should的用法。
should除表示“应该”外,还可用于表示情感、意志等句中的that从句。
译“竟然、居然”。
例如:You can’t imagine that a well-behaved gentleman _____ be so rude to a lady.A. mightB. needC. shouldD. would (答案C)第二节推测1.根据某一事实、现象推测可能发生的情况。
用must, may, might。
下表比较了三者表示推测肯定程度的差别,以及对不同情况推测的表达方式。
例:You must be tired. Go home and have a good rest. (对目前的推测) The light is on in the lab. Mr Li must still be doing experiments. (对目前的推测)Sorry I'm late. I might have turned off the alarm clock and gone back to sleep again.(对过去的推测)(2000北京春季)注:1)must表示推测仅用于对当前和已发生的情况,不能用于推测将来可能发生的事情。
must表示推测仅用于肯定句。
在否定句和疑问句中,必须用can / could取代must。
Mr Li can’t still be doing experiments at present.My English-Chinese dictionary has disappeared.Who ___________ have taken it?A.should B.must C.could D.would 答案C 2)may / might可以用于推测将来可能发生的情况,既可用于肯定句,也可用于否定句,但不能用于疑问句。
在疑问句中,同样使用can / could。
例:1. —Is John coming by train?— He should, but he________not. He likes driving his car.A. mustB. canC. needD. may 答案D (02全国)2. — Your son may return to Nanjing tomorrow by way of Hong Kong.— Wonderful! But how can he come, by air or sea?2.根据经验或惯例对某一情况进行推测,用should或ought to,常译成“按理应该…”或“可能会……”。
I t’s nearly seven o’clock. Jack should be here at an y moment. 时间已将近7点了,按理Jack该回来了。
第三节1.表示“当时本应该做,而实际上没有做”,用:①should have done或ought to have done②could have done或might have done句型①责备的语气强于句型②例:1. Mr. White should have arrived at 8:30 for the meeting, but he didn’t’ show up.2.He might have given you more help, even though he was busy. 2.表示“当时没有必要”做某事①needn’t have done当时做了某事,但事实上没有必要Y ou needn’t have told him the news; he knew it already.didn’t have to do通常指当时某事没有必要做且没有做。
