初中英语语法之情态动词用法及练习题(含答案)
情态动词用法及练习题一、情态动词的概念：情态动词主要用以表明说话者对某一行为的态度和观点，主要包括揣测、判断、需要及各种意愿。
常见的情态动词有can、may、could、must、have to、should、would等。
二、情态动词的特征(1)情态动词本身有词义，但词义不完整，因此不能独立作谓语，只能和主要动词一起构成谓语。
例如：I can play the piano.（ can play整体为谓语）(2)其后动词使用原形。
例如：You should lie down.(3)情态动词一般没有人称和数的变化(即不管是何人称，后面接的情态动词都不变)。
例如：I/She can sing.(4)它的否定式一般是在其后加 not构成，在一般疑问句中通常将其提到句首。
结构如下：①肯定句：主语+情态动词+动词原形+其他。
例如：He can swim.②否定句：主语+情态动词+not+动词原形+其他。
例如：He can't swim.③一般疑问句：情态动词+主语+动词原形+其他？Yes，主语+情态动词. No,主语+情态动词+not.例如：-Can he swim?-Yes, he can. No,he can’t.④特殊疑问句：特殊疑问词+情态动词+主语+动词原形+其他? 例如： -What can he do ?-He can swim.三.情态动词的用法(1)can的用法①表示“能力”Can you sing?你会唱歌吗?②表示客观条件允许You can listen to music here.你可以在这里听音乐。
You can’t park your car here. 你不能在此停车③can用在否定句和疑问句中时，有时表示说话人的怀疑、惊异、或猜测：It can’t be true.这不可能是事实Can it be true?这可能是真的吗？④.can的搭配用法：A.as +adj./adv.+as one can/could “尽可能，尽量……”，如：The man took his child to the hospital as quickly as he could.这个男人尽可能快地将孩子送去医院。

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。
---- C an I go now? Yes, you can. / No, you can 此时可'与t. 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) 。

——不，他不可能在办公室里。
他今天早晨飞往加拿大了。
考查情态动词。
A. needn't不需要；B. shouldn't不应该；C. can't不可能；D. mustn't表示禁止，不可以。
根据下文He flew to Canada this morning.他今天早晨飞往加拿大了，可以判断他不可能在办公室里，表示否定推测，应用can't“不可能”，故答案选C。
2．C解析：C【解析】【详解】句意：--听! 狼在叫! --它不可能是狼，因为狼从来不会在这个时候出来。
A. mustn’t禁止；B. needn’t没有必要；C. can’t不可能；D. don’t构成一般现在时的否定句。
根据“because a wolf never comes out at this t ime因为狼从来不会在这个时候出来”，可推断它不可能是狼，故选C。
【点睛】情态动词表推测的用法：can表示“可能”；can’t表示“不可能”；may表示“可能”，must表示“一定”，注意mustn’t表示“禁止”不表示推测，表示否定推测要用can’t.3．C解析：C【解析】【详解】句意：——你认为网上购物安全么？——我觉得是的。
淘宝上，消费者可以无理由退货，但是他们要承担运费。
考查情态动词辨析。
A. can’t; can不能，能；B. must; must必须，必须；C. can; have to可以，不得不；D. mustn’t; can禁止，能。
根据句意表示的是顾客能退货，是可以，第一空用can；但是不得不承担运费，非主观情愿用have to。
故选C。
4．D解析：D【解析】【分析】【详解】句意：设计者已经尝试了所有可能的方法使机器变轻，所以你不必担心它的重量。
must必须；一定；may可以；可能；can’t不能；不可能；needn’t不必，没有必要。
根据句意The designer has tried every possible way to make the robot light可知，设计者在努力使机器变轻，所以担心是没有必要的。
故应选D。
5．D解析：D【解析】【分析】句意：-我们现在能过马路了吗？-不，我们不能，我们要等到交通灯变绿。
couldn’t不能；needn’t不需要，不必；shouldn’t不应该；mustn’t禁止，不要。
根据句意We have to wait until the light turns green可知，在红灯的时候是禁止过马路的，因此这里的语气比较强，故应选D。
6．B解析：B【解析】【详解】句意：——妈妈，我从快递公司收到了一个大箱子。
它是什么？——我不确定。
可能是你祖母送的礼物。
考查情态动词。
should应该；might可能；must必须； will将，会。
根据“I’m not sure”可知下文是没有把握的肯定推测。
根据题意，故选B。
7．C解析：C【解析】【详解】句意：--这栋楼是多么好呀！它用来做什么的？--它可能是一个旅馆，我不确定。
