高中英语情态动词精讲与解析 概说 助动词(auxiliary)主要有两类：基本助动词(primary auxiliary)和情态助动词(modal auxiliary)。基本助动词有三个：do, have和be；情态助动词有十三个：may, might; can, could; will, would; shall, should; must, need, dare, used to, ought to. 上述两类助动词的共同特征是，在协助主动词构成限定动词词组时，具有作用词的功能： 1）构成否定式： He didn't go and neither did she. The meeting might not start until 5 o'clock. 2）构成疑问式或附加疑问式： Must you leave right now? You have been learning French for 5 years, haven't you? 3）构成修辞倒装： Nowhere can he obtain any information about his sister. Hardly had he arrived when she started complaining. 4）代替限定动词词组： A: Who can solve this crossword puzzle? B: Tom can. A: Shall I write to him? B: Yes, do. 情态助动词的特征 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： 1）除ought和used以外，其他情态动词后面只能接不带to的不定式。如果我们把ought
最新英语语法情态动词归纳总结 一、单项选择情态动词 1．Mr. Smith is almost on time for everything. How ________ it be that he was late for the meeting? A．can B．should C．may D．must 【答案】A 【解析】 【详解】 考查情态动词辨析。句意：史密斯先生几乎任何事情都是准时的。他怎么可能开会迟到了？ A. can可能，可能性，表示可能性时，常用于否定句和疑问句中，且有时还带有“惊奇、不相信” 等感情色彩。B. should 应该； C. may也许，表示可能性时常用于肯定句中，不用于疑问句中。D.must常用于肯定句中表推测，“一定……”的意思；本题是强调句型的一个变式：强调其特殊疑问句how的形式。根据前句“斯密斯先生几乎是很准时”可推测出“怎么可能开会迟到呢？”。根据句意可知，用于疑问句中的“可能性”且有不相信的色彩，四个选项只有“can”符合题意。故选A 【点睛】 情态动词就是表示说话者对事情的一种看法，也就是一种语气。情态动词的用法一直是命题者常设置的考点和重点，平时要加强记忆。 2．--- Oh, my God! I just missed the last bus back home. --- That’s really bad. I’m sure you ______ it, but you just didn’t hurry up. A．had caught B．could have caught C．could catch D．can catch 【答案】B 【解析】 【详解】 考查情态动词+have done结构。句意：——哦,我的上帝!我刚好错过了回家的末班车。——这是非常糟糕的。我肯定你能赶上，但你就是不抓紧。could have done“本来能做而没有做”。故选B。 3．-- Did Jim come? -- I don’t know. He _______ while I was out. A．might have come B．might come C．must have come D．should have come 【答案】A 【解析】 【详解】 考查情态动词推测用法。句意：Jim来了吗？--我不知道，在我不在的时候，可能来过。根据前文I don’t kn ow.可知，说话者不知道Jim来没来，因此后文推测来过，但是语气很不确定，故可知选A。对过去情况的推测为情态动词+have done，must have done 一定做了某
