初中英语语法知识—情态动词的综合训练

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。

初中英语情态动词详细用法归纳（含练习及答案）情态动词有具体的词义, 但也同助动词一样, 需要与其他词语一起构成句子的谓语, 另外情态动词没有人称和数的变化, 情态动词后必须跟动词原形。

1.ca.的用法:（1）.表示能力、许可、可能性.表示能力时一般译为“能、会”.即有种能力, 尤其是生来具备的能力.如：Sh.ca.swi.fast.bu..can’.. 她能游得很快, 但我不能。

.ca.se.wit.m.eyes.我用眼睛看。

could是can的过去式。

表示过去的能力.b.abl.t.d.sth.常常指经过努力，花费了时间和劳力之后才能做到某事。

is/am/ar.abl.t.d.sthwas/were able to do sth.（2）.表示许可, 常在口语中。

如: .m.dictionary..你可以用我的字典。

（3）.表示推测, 可能性, 意为“可能”.常用于否定句和疑问句中.此时can’.译为.不可能”.如：Ca.th.new.b.true.这个消息会是真的吗？—Ca.i.b.ou.teacher?那个人有可能是我们老师吗？—No.i.can’.b.ou.teacher.H.i.o..visi.t.th.Grea.Wall.不可能。

咱们老师正在游览长城呢。

【例题】—.thin.Mis.Ga.mus.b.i.th.library.Sh.sai.sh.woul.g.there.—No.Sh.__b.there..hav.jus.bee.there..A.can’.B.mustn’.C.needn’.D.wouldn’t【解析】根据下文“我刚去过那儿”可知, 应为“不可能”, can’t 表示推测[答案] Acould的用法:（1）.can的过去式, 意为.能.会”, 表示过去的能力。

如: H.coul.writ.poem.whe.h.wa.10. 他十岁时就会写诗。

（2）.could在疑问句中, 表示委婉的语气, 此.coul.没有过去式的意思。

情态动词专项练习(附答案)一、初中英语情态动词1．—Look! The woman at the school gate ______be her headmaster.—No, it ______ be her. She is holding a meeting in the office now.A. must; can'tB. must; mustn'tC. can; needn'tD. may; mustn't【答案】 A【解析】【分析】句意：——看！学校门口的那个妇女一定是她的校长。

——不，不可能是她。

第一空，must表示“一定”；空二，根据She is holding a meeting in the office now. 她现在正在办公室开会，可知，不可能是校长，用can't，表示不可能。

故选A。

【点评】考查情态动词辨析。

注意不同情态动词的用法，注意理解句意。

2．Teenagers allowed to drive .A. should not beB. should be notC. not should be【答案】A【解析】【分析】句意：年轻人不应该被允许驾车。

Should是情态动词，其否定表达一般在在后面加副词not，故选A。

【点评】此题考查含有情态动词的被动语态的否定形式。

平时注意记忆情态动词的记忆和用法。

3．You be tired after walking for such a long time. Sit down and have a rest.A. canB. can'tC. mustn'tD. must【答案】 D【解析】【分析】句意：走了这么长时间你一定很累了。

坐下休息一下吧。

can能，能够，can't不能，对事物进行否定推测；mustn't一定不是，禁止，must一定，对事物进行肯定推测，根据after walking for such a long time，可以肯定你一定很累，所以是进行肯定推测，情态动词使用must，故选D。

（完整版）初中英语情态动词专项练习题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/mightnot（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。
