►考向二 情态动词特殊用法辨析
高频易混易错梳理/归纳
1、shall用于第一、三人称疑问句表示征求对方意:见;用于第二、三人称肯定句或否定句表示说话人给予对方的“禁止、命令、警告、允诺或威胁等”。should用来表示建议、责任、义务时,可译为“应该,应当”,此时可用ought to替换;可用来表示惊讶、忧虑、赞叹等不满情绪(用在疑问句中);还可用来委婉地陈述自己的意见。
【考例】Schools _________allow students at least one hour a day for sports.
A. would B. might C. should D. could
[答案]C。[解析] 此处用情态动词should的用法。should表示“应当…‘应该”的含义比其他三个词更强些。
2、 “had better+动词原形”意为“最好做……”,否定句式为had better not。“would rather+动词原形”意为“宁可,宁愿”,否定句式为would rather not。
【考例】--What about playing football this afternoon, Sam?
--I would rather _______ at home than ____________ football. It's too hot outside.
A. stay; playing B. stay; play C. to stay; to play D. to stay; playing
[答案]:A。[解析]本题考查了would rather的固定短语的应用。译文为:萨姆,今天下午出去打球怎么样?和踢足球相比,我宁愿呆在家里,外面太热。Would rather do A than do B和做B比起来,宁愿做A。
3、“used to+动词原形”表示“过去常常做某事”或表示过去的一种惯常状态。
【考例】He used to ________ in the sun, but now he is used to _________ at night.
A. read, read B. reading, read C. read, reading D. reading, reading
[答案]:C。[解析]考查固定结构的用法。Used 后接动词不定时,be used to 后接动名词。故选C。
4、could有时不表示时态
1)提出委婉的请求,(注意在回答中不可用could)。例如:
--- Could I have the television on? 我能看电视吗?
--- Yes, you can. / No, you can't. 可以/不可以。
2)在否定句、疑问句中表示推测或怀疑。例如:
He couldn't be a bad man. 他不大可能是坏人。
must用在肯定句中表示较有把握的推测,意为"一定"。否定推测用can't。例如:
【考例】You ________be tired after working for eight hours without a rest.
A. can B. may C. must D. need
[答案]C。[解析] 本题考查情态动词must,can,may,need的区别。本题由题意人手,“你工作了八个小时没有休息肯定很累。”情态动词must在此表示肯定的推测。
【考例】一Look at the boy running on the ground.Is it Davis?
—It ____be him.I saw him go to the teacher's office just now.
A.must B. can't C.could D.might
[答案]B。[解析] 表推测时否定句中用can't。表示“不可能”,因为他已经去了老师的办公室。
6、need和dare这两词既可做实义动词用,又可做情态动词用。作为情态动词,两者都只能用于疑问句,否定句和条件句。need作实义动词时后面的不定式必须带to,而dare作实义动词用时, 后面的to 时常可以被省略。
1) 实义动词:need(需要, 要求) need + n. / to do sth
2) 情态动词:need,只用原形need后加do,否定形式为need not。例如:
Need you go yet? 你要走了吗?
Yes, I must. / No, I needn't.是的,我要走了/不,不急着走。
