情态动词精品学案 情态动词解读: ①本身有一定的词义，表示说话人的情绪、态度或语气的动词。 ②不能单独作谓语。 ③和其他动词原形构成谓语。 ④谓语动词之前。 ⑤无人称和数的变化。 ⑥否定式构成是在情态动词后面加“not”。 ⑦个别情态动词有现在式和过去式两种形式，过去式可以用来表达更加客气、委婉的语气，时态性不强，可用于过去，现在或 将来。 经典例句： We can be there on time tomorrow. 我们明天能按时去那儿。 May I have your name? 我能知道你的名字吗？ Shall we begin now? 我们现在就开始吗？ How dare you treat us like that! 你怎么敢那样对待我们! We can't carry the heavy box. 我们搬不动那箱子。 情态动词考点： 1.情态动词表示推测。 2.情态动词的基本用法。 3.情态动词的答语。 1 / 17
常见情态动词： 情态动词有can (could), may (might), must, have to, shall (should, will (would), dare (dared), need (needed), ought to等。 情态动词的基本用法： 一、can, could 1) 表示能力（体力、知识、技能）时，等于be able to 。 a)Can you lift this heavy box?（体力） b)Are you able to lift this heavy box? c)Mary can speak three languages.（知识） d)Is Mary able to speak three languages? e)Can you skate?（技能） 此时可用be able to代替。 2) can表示请求和允许。 -----Can I go now? ----- Yes, you can. / No, you can’t. 此时可与may互换。在疑问句中还可用could, might代替，不是过去式，只是语气更委婉，不能用于肯定句和答语中。（特别注明：这是在表示请求和允许的时候。） ---- Could I come to see you tomorrow? ---- Yes, you can. (No, I’m afraid not. ) can't在否定句中可以表示命令，不允许，但是语气比mustn't弱，具有劝慰的意思. 3)can表示“有时会”： A kind person can lose temper sometimes. 4）表示与五种感官和知觉的动词连用。 I can hear/ see you clearly from here. You can imagine how annoyed she was ! 2 / 17
情态动词详细用法归纳 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. can 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：She can swim fast, but I can’t . 她能游得很快，但我不能。 could是can的过去式。表示过去的能力。be able to do sth. 常常指经过努力，花费了时间和劳力之后才能做到某事。 （2）表示许可，常在口语中。 如：You can use my 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’t 译为“ 不可能”。如：Can the news be true? 这个消息会是真的吗？ —Can it be our teacher?那个人有可能是我们老师吗？ —No, it can’t be our t eacher.

（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）

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。

A．need to have B．need to C．needed to D．need have 【答案】D 【解析】 【分析】 【详解】 考查情态动词+have done。句意：——你昨天参加实验项目的会议了吗?——是的，但我想我（本来）不需要，因为我的主管在那里。Think/suppose等宾语从句中如果有否定词时，要把从句的否定词not前移，即“否定前移”。所以not是从句中的否定词。“need have done”意为“本来有必要做而未做”；“needn’t have done”指过去本来没必要做而做了。根据上一句时间状语“yesterday”可知本句指的是过去发生的事。结合第二句“because my director was there(我的主管)在”可推断出，我本来不必要去。故选D。 3．-–Mary knows the city quite well. --She______ well have been there before.
