语法学案5：情态动词（Modal Verbs） 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. B: Yes, do. 语气和态度。 1. 后面一般+动词原形 2. 一般没有人称和数的变化即第三人称单数不加-s 3. 一般只有现在式和过去式两种形式，但可以表示现在时间，过去时间和将来时间。 4. 情态动词没有非谓语形式，即没有to do, doing, done等形式 现代英语语法还将be able to(能够), had better(最好), would rather(宁愿),used to(过去常常)等列为情态动词。
情态动词的基本用法及其区别 最近几年高考试题中常常借助语境来考查情态动词的基本用法及其区别，因此在平时学习时准确理解和掌握情态动词的基本用法十分重要。情态动词的用法复杂多变，在高考试题中，命题者常常利用语境和句子之间意义上的细微差别来考查学生对情态动词的理解和掌握。对于情态动词，除了要求考生能够准确掌握它们的基本用法外，还要充分利用高考试题所设置的语境来分析句子之间所体现的特殊关系。下面就近几年来高考试题中出现的情态动词的考点进行归纳分析，以便同学们复习掌握。 一、用“情态动词＋have ＋done”结构表示对过去动作的推测，高考试题中常用过去时态或过去的时间状语给以暗示。情态动词的这一用法可以用“对立统一”来概括。 1．当试题的前句和后句在动作和意义上相互补充说明，且整个句意在动作和时间上是一个整体时，我们可用“统一”关系来解决这样的试题。常见的结构有： must have done： 表示对过去动作的肯定推测，常译作“一定做了……”，只能用于肯定句中。其否定形式为can’t／couldn’t have done 疑问式为Can／Could...have done﹖。 could ／might have done：表示对过去发生的动作的可能性推测，常译作“可能做了……”。如： 1) My sister met him at the Grand Theater yesterday afternoon, so he ＿＿＿＿＿your lecture． A．couldn’t have attended B．needn’t have attended C．mustn’t have attended D．shouldn’t have attended 本题选A。 2) Jack ＿＿＿＿yet, otherwise he would have telephoned me． A．mustn’t have arrived B．shouldn’t have arrived C．can’t have arrived D．need not have arrived （C） 2．当试题的前后句在动作和意义上构成转折关系时，常借助“but, however, instead”等词来表示过去的动作与客观事实不符，这时我们就可以用“对立”关系来解决这样的试题。这种结构常见的有： should have done ／ought to have done：表示过去本应该做某事而实际上没有做。 should not have done ／ought not to have done：表示过去本不应该做某事但事实上却做了。 need have done：表示过去本来有必要去做某事，但事实上没有做。 need not have done：表示过去本来没有必要做某事，但事实上却做了。如： 3) I was really anxious about you．You ＿＿＿＿＿home without a word．(NMET2001) A．mustn’t leave B．shouldn’t have left C．couldn’t have left D．needn’t leave “本不应该离家出走却走了”，故本题选B。 4) I told Sally how to get here, but perhaps I ＿＿＿＿＿for her．

一、考点回顾 1、情态动词的基本用法 (1)can、be able to 和could ①can和be able to都表示能力，意思上没多大区别。 can只有现在和过去时，而be able to则有更多的形式。 但当成功地完成某一具体动作时，通常不用could而用was/were able to来表示。 这时was/were able to 相当于managed to，表示经过一番努力，终于能够完成某事。 ②can和could can和could都可以表示能力、技能、许可、建议或请求和可能性。但比较委婉客气地提出问题或陈述看法，一般用could，回答时则用can。 (2)may/might ①may/might表示可能，但may比might可能性大。 ②may/might表示“允许”，may用于现在时或将来时，might常用在间接引语中表过去时，但might也可用于现在时间，表示比较委婉的语气，回答用may。如： ③may / might 表示建议或请求，但might比may 更客气，意思更肯定而无过去时态的含义 用may表示推测一般不用于疑问句，在疑问句中通常用can来代替。 May I ... 问句常见的肯定回答和否定回答。 肯定回答 Yes, please.Certainly.Yes, of course.Sure.Go ahead, please. 否定回答 No, you can't. （最常见）No, you mustn't. （具有强烈禁止的意思） Please don't. You'd better not.I don't think you can.I'm sorry it's not allowed. （3）must ①must表示必须，应该，没有时态变化。 ②must表示肯定的推测。如： ③mustn’t 表示禁止做某事。如： （4）have to have to 表示“必须、不得不”，是由于某种外界（客观）原因而“必须”，“不得不”做某事，也可表示经常的或习惯性的事“必须”做。have to的否定形式表示不必。have to可用于多种时态中。如： （5）should / ought to ①should和ought to表示应当、应该，前者比后者语气轻。 ②should / ought to 表推测。 ③should / ought to的否定形式表示禁止之意。如： ④should可表示陈述意见，推出建议或请求；而ought to可以表示劝告之意。如： （6）will / would ①will 用于各种人称表示“意志”、“意愿”或“决心”等，否定式won’t + 动词。如： ②will用于疑问句中，常用在第二称时表示说话人向对方提出“请求”或“询问”如： ③will 表示习惯性的动作，有“总是”、“惯于”的含义。如： ④would 表示客气的请求、建议或意愿。如： ⑤would 表示过去反复发生的动作,总是会。 （7）need need 作“必要”讲，既可作情态动词，也可作实义动词。作实义动词时后面的动词不定式要
