本题考查情态动词表示推测的用法。
can表示能力或客观可能性；may表示许可或可能性（可能性较小）；must表示肯定的推测，根据“工作八小时没有休息”，这种情况下“肯定”是累的，所以用must；should表示应该。
2. ______ I use your pen?A. CanB. MustC. NeedD. Will答案解析：A。
这里考查表示请求许可的情态动词。
Can可以用来表示请求许可，意为“我可以用你的笔吗”；Must表示必须；Need表示需要；Will表示将来或意愿，在此语境下不合适。
3. She ______ speak three languages when she was ten.A. canB. couldC. mayD. might答案解析：B。
本题考查can和could表示能力的用法。
can表示现在的能力，could表示过去的能力，句中提到“当她十岁的时候”是过去的时间，所以用could；may和might表示可能性或许可，不符合题意。
4. It ______ rain tomorrow, so take an umbrella with you.A. canB. mayC. mustD. should答案解析：B。
这里考查表示可能性的情态动词。
may表示可能性（可能性不是很大），“明天可能会下雨”；can表示能力或客观可能性（通常用于否定句和疑问句表示推测）；must表示肯定的推测，这里不是肯定会下雨；should表示应该，不符合语境。

高考英语情态动词语法专题训练(名师精讲必考语法知识点+实战真题，值得下载练习)一、情态动词的定义情态动词是一种本身有一定的词义，表示说话人的情绪、态度或语气的动词，但不能单独作谓语，只能和其他动词原形构成谓语。
情态动词数量不多，但用途广泛，主要有：can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would) .二、情态动词的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，情态动词放在主语之前。
•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? 你要什么？•How dare you treat us like that! 你怎么敢那样对待我们!三、情态动词的语法特征1）情态动词不能表示正在发生或已经发生的事情，只表示期待或估计某事的发生。
2）情态动词除ought 和have 外，后面只能接动词原形。
3）情态动词没有人称，数的变化，即情态动词第三人称单数不加-s。
4）情态动词没有非谓语形式，即没有不定式，分词，等形式。
四、情态动词的用法（一）. can; could; be able toCan 1. 表示“能力”(此时过去时是could) What can you do?2. 表示许可、请求，“可以”。
在口语中，can可以代替may表示许可，而may比较正式。
（此时用could 或might语气更委婉）--Can/Could I go now?--Yes, you can.3 表示推测（否，疑），把握很大,could也可表推测（肯，否，疑）,把握比can小。
--Look! Someone is coming! Who can it be?--It can’t be him. He has gone to Paris.（不可能）He could be here soon. 他很快就来。

“must”在这里表示肯定的推测，意为“一定”。
从“你看起来很累”这个语境可以推断出“你昨晚一定熬夜了”。
“can”表示能力或可能性，在此处不合适；“should”表示应该，不符合语境；“need”需要，通常用于否定句或疑问句。
2.I______speak French fluently when I was in college.A.canB.couldC.mayD.might答案解析：B。
“could”表示过去的能力。
“can”表示现在的能力；“may”和“might”表示可能性，不是能力。
3.You______play football in the street. It's very dangerous.A.mustn'tB.needn'tC.may notD.couldn't答案解析：A。
“mustn't”表示禁止，不允许在街道上踢足球，因为很危险。

解析：本题考查情态动词的用法。
A选项“can't”表示不能，没有能力做某事，在这里不符合语境；B选项“mustn't”表示禁止，不允许做某事，而句中是说不需要现在还书，不是禁止还书；C选项“needn't”表示不需要，不必，符合句子意思，即你不必现在还书，可以保留到下周；D选项“may not”表示可能不，与句子表达的不需要的意思不符。
2. - ______ I take this seat? - Yes, you may.A. MustB. WillC. MayD. Should答案：C。

A选项“Must”表示必须，用于询问时是问是否必须做某事，不符合此处询问是否可以坐这个座位的语境；B选项“Will”表示将要，意愿，不能用于请求许可；C选项“May”用于表示请求许可，通常用于正式或礼貌的场合，这里问是否可以坐这个座位，回答是可以，所以选C；D选项“Should”表示应该，不符合请求许可的语境。
3. He ______ be at home. I saw him in the library just now.A. mustn'tB. can'tC. may notD. needn't答案：B。
解析：本题考查情态动词表示推测的用法。
A选项“mustn't”表示禁止，不是推测用法；B选项“can't”表示不可能，根据后面说我刚刚在图书馆看到他，所以他不可能在家，这种推测是基于事实的否定推测；C选项“may not”表示可能不，语气比较弱，没有“can't”那么肯定；D选项“needn't”表示不需要，不是推测用法。
