练习答案与解析
1. B 从第二个分句“他太矮了”可以推知说话者持否定态度，needn't意思是“没有必要”，与语境不符。
2. C 根据句意“我已经告诉她怎样到那儿，但是或许我应该给她写下来”可知，说话者含有“后悔、遗憾”的意味，应使用“情态动词+完成式”形式，“must+完成式”表示对过去的肯定推测，“should+完成式”才表示虚拟意义。
3. C 根据第二分句“否则的话他就会给我打电话了”可知“Jack肯定还没到”，“c an't+完成式”意思是“根本不可能”。
4. A 从第二分句可知，这是妇女和儿童专用候车室，因此你“不准”坐在这儿。mu stn't表示“禁止，不准”。
5. B can在此表示许可。
6. D 从后一句“他喜欢开车”可知说话者把握不大。must not不表示推测，can no t的语气太绝对，意思是“根本不可能”。
7. D shall用于第二、三人称，表示说话人给对方的命令、警告、允诺、威胁等意思。
8. C should在此表示惊讶的感情色彩，意思是“竟然”。
9. B 对祈使句的肯定回答用I will；否定回答用I won't。
10. D 根据句意“我今天上午在会议室没见到她”，所以“她根本不可能在会上发言”。表示“根本不可能”用can't/couldn't have done形式。

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.

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
