测,might的语气比may弱一点.这种结构主要用于肯定句和否定句,疑问句改用can或could.如：They may not have known it beforehand.
4.“need + have + 过去分词”表示过去做了不必做或不需要做的事情,或过去做某事纯属多余.如：I needn't have bought so much wine—only five people came.
5.“should / ought to + have + 过去分词”表示过去本该做某事但没做,其否定式表示过去不该做某事但做了,这种句式含有不满或责备之意,ought to的语气比should强一些.如：

高中英语情态动词精讲与解析
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
高考英语情态动词讲解
（一） 情态动词常考点 （一） 表能力 can be able to will be able to could was/ were able to could have + ?? ???? ?? ?????? ?表示现在的能力 ：表示将来的能力 表示过去的能力 过去分词：表示过去有能力做但未做 如：I am starving to death 。I can eat two bowls of rice now 。 （现在的能力）我快饿死了，现在我能吃两碗米饭。 If you have a good sleep ，you will be able to work out this problem 。 （将来的能力）如果你好好睡一觉，你将能够解出这道题。 The fire spread through the hotel very quickly but everyone was able to get out 。 （过去有能力做并且成功的做了某事）尽管这场大火迅速蔓延到了整个宾馆，但是每个人都能够逃出 去。 I could have worked out the problem ，but I didn ’t 。 （过去有能力做但未做）我本来可以解决这个问题，但没有解决。 （二） 表推测（可能性） 1. 可能性可分为客观的可能性和具体事情实际发生的可能性两种。所谓客观的（理论的）可能性即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。情态动词can 可用于肯定句中表示客观的（理论的）可能性，而表示具体事情实际发生的可能性时，can 一般不用于肯定句。如： Accident can happen on such rainy days 。 这样的多雨天气有可能会发生事故。（客观的可能性） Peter may come with us tonight ，but he isn ’t sure yet 。 彼得今晚可能和我们来，但他还没确定。（实际可能性，不用can ） 2. 表示具体事情实际发生的可能性： （1）表示具体事情实际发生的可能性的层次比较 （2）表示具体事情实际发生的可能性时，may ，must 常用于肯定句，一般不用于否定句和疑问句（may not 表示“可能不”）；can 常用于否定句、疑问句或感叹句中，表示疑惑、惊讶或不相信等意思；could 既可用于肯定句，又可用于否定句、疑问句中。如： This can ’t/ couldn ’t be done by him 。（表不相信） 这不可能是他做的。 This may not be done by him 。（表不确定） 这可能不是他做的。 He could be on his way home now 。（could 不如may/ might 常用） 他现在可能在回家的路上。 Can this be done by him ？（表示疑惑、惊讶） 这可能是他做的吗？ Mr. Bush is on time for everything 。How can it be that he was late for the opening ceremony ？（表示疑惑、惊讶） 布什先生做每件事都很按时。他怎么可能在开幕仪式上迟到呢？ I didn ’t hear the phone 。I must have been asleep 。（表肯定） 我没听到电话。我肯定已经睡着了。 3. would ，could ，might 并不一定与过去时间有关，而是表示可能性弱于他们相应的现在时形式。另外should 也不一定与过去时间有关。如： This may/ might be done by him 。（后者比前者语气弱）
高中英语情态动词讲解与练习(含答案)
高中英语语法之情态动词 （一）情态动词的定义：情态动词表示说话人对某一动作或状态的态度。 （二）情态动词的特点：1）有一定词义；2）不受主语人称和数的变化影响；3）与主要动词 的原形（或称不带to的不定式）一起构成谓语（除ought to作固定词组看待）。 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。 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： 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 to 和used to看做是固定词组的话，那么，所有情态动词无一例外地只能接不带to的不定式：We used to grow beautiful roses. I asked if he would come and repair my television set. 2）情态助动词在限定动词词组总是位居第一：They need not have been punished so severely. 3）情态助动词用于第三人称单数现在时的时候，没有词形变化，即其词尾无-s形式： She dare not say what she thinks. 4）情态动词没有非限定形式，即没有不定式和分词形式，也没有相应的动名词： Still, she needn't have run away. 5）情态助动词的“时”的形式并不是时间区别的主要标志。在不少场合，情态助动词的现在 时和过去时形式都可以表示现在、过去或将来时间：Would you mind very much if I ask you to do something? She told him he ought not to have done it. 6）情态助动词之间是相互排斥的，即在一个限定动词词组中只能出现一个情态助动词，但 有时却可以与have和be基本助动词连用：You should have washed the wound. Well, you shouldn't be reading a novel. （三）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,has) to,used to ⑤情态动词表猜测 （四）情态动词的基本用法 1. can (could) 1）表示能力，could主要指过去时间。 Two eyes can see more than one. 两只眼比一只眼看得清。 Could the girl read before she went to school? 这女孩上学前能识字吗？ 2）表示可能（理论上或是逻辑判断上）。 The temperature can fall to –60℃, that is 60℃ below freezing. 气温可降至—60℃，也就是零下60℃。 t) have enough money for a new car. 他不可能有足够的钱买新车。 He can′ t (couldn′ re walking around in the wood. You could start a fire. You mustn′ t smoke while you′

高考英语情态动词及其解题技巧及练习题(含答案)
高考英语情态动词及其解题技巧及练习题(含答案) 一、单项选择情态动词 1．It_____ have been Tom that parked the car here, as he is the only one with a car. A．may B．can C．must D．should 【答案】C 【解析】 【详解】 考查情态动词表猜测的用法。句意：一定是汤姆把车停在这儿的，因为他是唯一有车的人。A. may可能；B. can可能；C. must一定；D. should应该。由as he is the only one with a car.可知一定是他把车停在这里的，非常有把握的肯定推测，故选C。 2．We’ll make the final decision on our scheme. ______ you change your mind, please inform us as soon as possible. A．Should B．Were C．Would D．Had 【答案】A 【解析】 【分析】 【详解】 考查虚拟语气。句意：我们将对我们的计划做最后决定。如果你改变主意，请尽快通知我们。根据语境，此处用虚拟语气，表示与将来相反，从句用should+动词原形，省略if，should提前，陈述句是：If you should change your mind……。故选A。 【点睛】 虚拟语气中的倒装 当虚拟条件句中含有 were，had，should时，可以将if省略，然后将 were，had，should，移至句首： 1）If he should fail, he would kill himself. →Should he fail, he would kill himself. 万一失败，他就会自杀。 2）If I were you, I would do it at once. →Were I you, I would do it at once. 假若我是你，我就会马上做。 要是我能做此事，我一定会做。 3）If he had seen you yesterday, he would have asked you about it. →Had he seen you yesterday, he would have asked you about it. 他昨天要是看到了你，他就会问你这事了。 该小题属于上述的第一种情况。should作为情态动词，有一种特殊的用法：在虚拟条件状语从句中表示与将来事实相反的虚拟语气，可以把should放在句首，即主语前，从而省略从属连词if。原来的表述为：If you should change your mind。故选A。
