初中英语情态动词单选题60题1. You ______ play football in the street. It's too dangerous.A. can'tB. couldn'tC. may notD. might not答案:A,“can't”表示“不能,不可以”,语气较强,强调禁止。
“couldn't”是“can't”的过去式。
“may not”和“might not”表示“可能不”,语气较弱。
在这个语境中,在街上踢足球是绝对禁止的,所以用“can't”。
2. —______ I use your pen?—Sure. Here you are.A. CanB. CouldC. MayD. Might答案:A,“Can I...?”用于请求允许,语气较直接。
“Could I...?”语气更委婉。
“May I...?”也用于请求允许,较正式。
“Might I...?”较少使用,语气非常委婉。
这里直接请求用钢笔,用“Can”合适。
3. She ______ come to the party tonight. I'm not sure.A. canB. couldC. mayD. might答案:D,“may”和“might”都表示可能性,但“might”的可能性比“may”更小。
“can”和“could”一般不用于这种不确定的可能性推测。
这里不确定她来不来,可能性较小,用“might”。
4. We ______ help our parents do some housework at home.A. canB. couldC. shouldD. would答案:C,“should”表示“应该”,强调责任和义务。
“can”和“could”表示“能够”。
“would”表示“愿意,会”。

2. —______ you play the piano?—Yes, I can.答案:A解析:根据答语“Yes, I can.”可知问句用can 提问,意思是“能,会”。
3. She ______ speak English very well, but she can't write it well.A. canB. couldC. mayD. might答案:A解析:“speak English very well”表示一种能力,can 表示“能够,会”,符合句意。

6. We __________ go to the park tomorrow if the weather is nice.A. mayB. mightC. mustD. can答案:A解析:“may”表示可能性,“might”语气更委婉、不确定,“must”表示必须,“can”表示能够。
根据语境,如果明天天气好,我们“可能”去公园,这里可能性较大,用“may”。
7. She __________ be late for the meeting. I'm not sure.A. mayB. mightC. mustD. can't答案:B解析:“I'm not sure.”表明不确定,“might”比“may”语气更不确定,所以这里用“might”表示她“可能”会迟到。
情态动词情态动词是一种本身有一定的词义,但要与动词原形及其被动语态一起使用,给谓语动词增添情态色彩,表示说话人对有关行为或事物的态度和看法,认为其可能、应该或必要等。
情态动词后面加动词原形。
情态动词有四类:①只做情态动词:must,can(could),may(might)……②可做情态动词又可做实义动词:need,will③具有情态动词特征:have(had,has) to,used to,ought to④情态动词表猜测:一肯一否三不定(must一肯,can not一否,may,might,could,三不定。
)注:mustn't代表强烈禁止must表示主观,have to表示客观。
常用的有:can may could must have use.情态动词无人称和数的变化,情态动词后面跟的动词须用原形,否定式构成是在情态动词后面加"not"。
个别情态动词有现在式和过去式两种形式,过去式用来表达更加客气,委婉的语气,时态性不强,可用于过去,现在或将来。
情态动词属非及物动词,故没有被动语态。
情态动词表推测的用法小结(一)情态动词表推测的三种句式1.在肯定句中一般用must (一定),can,could(可能),might /may(也许,或许)。
e.g:(1)He must/can/may,might know the answer to this question.他一定/可能/也许知道这个问题的答案。
(2)It is cold in the room. They must have turned off the heating.屋里很冷,他们肯定把暖气关了。
2.否定句中用can’t / couldn’t(不可能),may not/might not(可能不)。
e.g:(1)It can’t/couldn’t be the headmaster. He has gone to America.这不可能是校长,他去美国了。
(2)He may not/might not know the scientist.他也许不认识那位科学家。
3.疑问句中用can/could (能……?)。
e.g:(1).Could he have finished the task?他可能把任务完成了吗?注:以上三种句式中情态动词的语气按程度都是依次递减的。
Might,could并非may,can的过去式,而表示语气较为委婉或可能性较小。
(二)情态动词表推测的三种时态1.对将来情况的推测,用“情态动词+ 动词原形”。
e.g:(1).She must / may / might / could arrive before 5.5:00前她一定/可能/也许到。
2.对现在或一般情况的推测,用“情态动词+ be”,“情态动词+be doing”或“情态动词+ 动词原形”。
e.g:(1).He must / may / might / could be listening to the radio now.他一定/可能/也许正在听收音机。
(2).He can’t ( couldn’t ) / may ( might ) not be at home at this time.这个时候他不可能/可能不在家。
3.对过去情况的推测,用“情态动词+ have +过去分词”。
e.g:(1).It must / may / might / could have rained last night .The ground is wet.地湿了,昨晚肯定/可能/也许下雨了。
(2).The door was locked. He can ( could ) not / may ( might ) not have been at home .门锁着,他不可能/可能不在家。
注:情态动词should /ought to表推测时,意为“想必会,理应……”但与“have +过去分词”连用时,则又可构成虚拟语气意为“本应该做某事却没做”。
例如:(4).It’s seven o’clock. Jack should/ought to be here at any moment.现在七点钟了,杰克理应随时到达。
(推测)(5).Tom should not /ought not to have told me your secret,but he meant no harm. (虚拟)汤姆本不该告诉我你的秘密,可是他并无恶意。
can 和could 表示推测的用法对现在或将来的推测,两者均可用,但can 通常只用于否定句或疑问句中,一般不用于肯定句,而could则可用于肯定句、否定句和疑问句;对过去的推测,应在can,could 之后接动词的完成式,且此时can仍只用于否定句或疑问句,不用于肯定句;而could 则可用于各种句型。
如:Can [Could] this be true? 这能是真的吗Where can [could] he have gone? 他能到哪里去了呢She can’t [couldn’t] have left so soon. 她不可能走得这么早。
注:could后接动词的完成式,除表示对过去的推测外,还可表示过去没有实现的可能性(即某事本来可以发生,却没发生),或委婉地责备某人过去应该做某事而没有去做(此时不用can)。
如:You could have started a little earlier. 你本可早点动身的。
You needn’t have cooked it. We could have eaten it raw. 你其实可以不煮熟(它),我们(本来)可以生吃。
can 和could 表示允许的用法表示现在的允许时,若是请求别人允许自己做某事,两者均可用,但用could 语气更委婉;若是自己允许别人做某事,一般只用can,而不用could。
如:Can [Could] I come in? 我可以进来吗“Could [Can] I use your pen? ”“Yes,of course you can.”“我可以借用你的钢笔吗?”“当然可以。
”(不能说Yes,you could.)表示过去的允许时,若表示过去一般性允许(即表示某人随时都可以做某事),用could;若表示在过去某一特定情况下允许进行某一特定的活动,则不用could。
如:When I lived at home,I could watch TV whenever I wanted to. 我住在家里时,想什么时候看电影就可以什么时候看。
(一般性允许)I was allowed to see the film yesterday evening. 昨天晚上允许我去看了电影。
(特定的允许,不能用could)can 和could 表示能力的用法can 表示现在的能力,could 表示过去的能力,要表示将来具备的能力通常be able to 的将来时态。
其中要注意的是,could 表示过去的能力,通常只用于表示过去一般性能力,而不表示过去具体某次特定情形下能够做某事的能力。
如:他学习很努力,所以考试能及格。
误:He studied hard and could pass the exam.正:He studied hard and was able to pass the exam.注:若在否定句中没有以上限制,即couldn’t 可表示过去特定情况下的能力,如可说He studied hard but still couldn’t pass the exam.口诀:情态动词两特点动词原形接后面,说话语气较委婉。
can "能力"may"许可",must"责任"或"义务"。
否定回答needn’t 换,"需要"need, dare"敢"。
should"应该",would"愿",have to"被迫"表客观。
