A．must put B．should have put C．might put D．might have put 【答案】D 【解析】【详解】考查情态动词。句意：——我的词典在哪里？我记得昨天放在这里了。——你或许放错了地方。“might have +动词+ed形式”表示过去可能完成的动作。根据所提供的情景Where is my dictionary? I remember I put it here yesterday.可判断出把词典放在某个地方发生在过去，所以要用“might have +动词+ed形式”。“should have + 动词+ed形式”表示“(过去)本来应该做某事”。must意为“一定”，是肯定的推测，与所提供的情景的矛盾。might put表示现在发生的事。故选D。 2．—I have something important to tell Jo hn. But I can’t find him. —His cell phone is here, so he ________ have gone too far. A．mustn’t B．needn’t C．wouldn’t D．can’t 【答案】D 【解析】【详解】考查情态动词。句意：——我有重要的事情要告诉John，但是我找不到他。——他的手机在这儿，所以他不可能走得太远。根据句意可知，此处是对过去的一种猜测，此处是表达不可能……，用can’t have done。故选D。 3．The room is so clean.

语法专题(三) 情态动词考点归纳考点一：情态动词表示能力 1．表现在的或一般的能力：表示现在的或一般的能力用can或be able to，can比be able to 使用得更普遍。can侧重指有能力做某事；而be able to更强调通过努力、克服困难做成某事。 A computer can't think for itself；it must be told what to do. He is a native speaker of English，so he can of course speak English quite well. 2．表示将来的能力：表示将来能力用will be able to。 If you have a good sleep，you will be able to work out this problem. 如果你睡个好觉，你就能做出这道题。 3．表示过去的能力： could表示过去一般的能力，即不表示做或未做某事；而was (were) able to do则表示过去有能力并且成功地做了某事，相当于managed to do something/succeeded in doing something。考点二：情态动词表示推测(可能性) 可能性可分为客观的(理论的)可能性和具体事情实际发生的可能性。 1．客观的(理论的)可能性指并不涉及具体某事是否会发生，此种用法常常可以说明人或事物的特征。can用于肯定句中表示客观的(理论的)可能性，can用于疑问及否定句中则表示实际发生的可能性。 The World Wide Web is sometimes jokingly called the World Wide Wait because it can be very slow. A left-luggage office is a place where bags can be left for a short time，especially in a railway station. 2．表示具体事情实际发生的可能性：

情态动词的用法完整详细

情态动词定义: 情态动词是一种本身有一定的词义,但要与动词原形一起使用，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。分类：情态动词有四类： ①只做情态动词：must,can(could),may(might),ought to ②可做情态动词又可做实义动词：need,dare ③可做情态动词又可做助动词：shall(should),will(would) ④具有情态动词特征：have(had) to,used to 位置: 情态动词在句中放在谓语动词之前, 谓语动词前若有助动词,则在助动词之前,疑问句中, 情态动词则在主语之前。 I can see you. Come here. 我能看见你，过来吧。 He must have been away. 他一定走了。 What can I do for you? 我能帮你吗？ How dare you treat us like that！你怎能那样对待我们！特点: 情态动词无人称和数的变化, 情态动词后面跟的动词需用原形,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。情态动词没有非谓语形式，即没有不定式，分词，等形式。 He could be here soon. 他很快就来。 We can't carry the heavy box. 我们搬不动那箱子。 I'm sorry I can't help you. 对不起，我帮不上你。基本助动词与情态助动词最主要的区别之一是，基本助动词本身没有词义，而情态助动词则有自己的词义，能表示说话人对有关动作或状态的看法，或表示主观设想： What have you been doing since? （构成完成进行体，本身无词义） I am afraid I must be going. （一定要） You may have read some account of the matter. （或许已经）除此之外，情态助动词还有如下词法和句法特征：
