一、选择题
1．C
解析：C
【解析】
【分析】
【详解】
句意：——妈妈，我必须和你出去吃饭吗？——不，你不必。亲爱的，你可以自由地做出你自己的决定。考查情态动词。A. shouldn’t不应该；B. mustn’t不允许；C. needn’t不必；
D. can’t不能。根据No, you , my dear. You’re free to make your own dec ision.可知此处为否定回答，must的含义是“必须、一定”，其否定形式mustn’t表示“禁止”的含义；在这里根据语境可知不是“禁止”的意思。对must开头的一般疑问句作否定回答，一般用needn’t或don’t have to，故答案选C。
2．C
解析：C
【解析】
【详解】
句意：--听! 狼在叫! --它不可能是狼，因为狼从来不会在这个时候出来。
A. mustn’t禁止；
B. needn’t没有必要；
C. can’t不可能；
D. don’t构成一般现在时的否定句。根据“because a wo lf never comes out at this time因为狼从来不会在这个时候出来”，可推断它不可能是狼，故选C。
【点睛】
情态动词表推测的用法：can表示“可能”；can’t表示“不可能”；may表示“可能”，must表示“一定”，注意mustn’t表示“禁止”不表示推测，表示否定推测要用can’t.
3．A
解析：A
【解析】
【详解】
句意：请你说大点声好吗？我不能很好地听到你说的话。考查情态动词辨析。can't不能，表示不能够；mustn't不许，表禁止；shouldn’t不应该，表劝诫；needn’t无需，表示没必要。本句表示“不能够”，根据句意语境，可知BCD三项意思都与句意不合，故选A。4．C
解析：C
【解析】
【详解】
句意：你已经完成了大部分工作，所以你明天不必这么早就开始工作。你可以9点来。
本题考查情态动词。can't不可能，mustn’t禁止，needn’t不必，couldn’t可能不。根据You have finished most of the work可知，你已经完成了大部分工作，因此明天不必这么早就开始工作，因此用needn’t，故选C。
5．B
解析：B
【解析】
【分析】
考点：考查动词。
【详解】
试题分析：句意：我希望你能来参加我的生日聚会。hope to do sth希望做某事；hope that 从句，希望……。但不能说hope sb to do sth；从句主语you，所以谓语动词不能用comes单数形式；come是实意动词，前面不能用are；所以选B。
6．C
解析：C
【解析】
【详解】
句意：乔的生日我给她买了一条漂亮的项链。她可能会喜欢，但是我不确定。
考查情态动词表示推测。can表示能、可以；may表示可能，might是其过去式；must表示一定、必须。根据题干中but I'm not sure．可知可能性较小的推测，则可用may或者might，B项中may后有系动词be，原句中有动词like，则只能用might。故选C。
7．B
解析：B
【解析】
【详解】
句意：——难道弗莱克不喜欢待在家里照顾他的小妹妹吗？——是的，但是他不得不这么做因为他的父母都去工作了。
考查一般疑问句。has to不得不；doesn’t have to不必。根据后面的both of his parents work 可知，弗兰克不得不在家照顾妹妹。而且but表示转折，跟前面表述的是相反的，问句是一个否定式的一般疑问句，回答“No+否定句”，no翻译成“是的”。故选B。
8．B
解析：B
【解析】
【详解】
句意：他可能喜欢咖啡。我看见他有时喝一杯。A. must必须；B. may可能；C. can’t不能；D. mustn’t禁止。根据下文I see him drink a cup at times.可知上文是可能喝咖啡。根据题意，故选B。
9．C
解析：C
【解析】
【分析】
【详解】
句意：——这个读书报告很重要。你必须仔细地写。——但我现在必须交上它。
考查情态动词。must必须，表示说话人主观上的看法；have to不得不，必须，强调客观需要。第一句表示说话人认为对方必须认真写，是主观看法，第二句表示客观需要不得不现在上交，故选C。
10．B
解析：B
【解析】
【详解】
句意：——我想买郭敬明的《小时代》。——你最好不要读他的书。他讲的故事与现实生
活相去甚远。
考查非谓语动词及固定句型。短语would like to do sth.愿意去做某事；第一空排除AC；You had better+动词原形，你最好做某事；You had better not+动词原形，你最好不要做某事。第二空排除D。根据题意，故选B。
11．B
解析：B
【解析】
【分析】
【详解】
句意：——杨小姐，我能从图书馆借这些书吗？——对不起，你不能。这些书仅供英语俱乐部的会员借阅。
考查情态动词的用法。can“能，会”，情态动词；could是can的过去式。表示请求允许（即请求别人允许自己做某事）时，既可用 can也可用could，但这里的 could 并不表示过去，而是表示现在，只是比can的语气更委婉。若表示给予允许（即自己允许别人做某事），一般只用can/can’t。综上所述，故选B。
12．C
解析：C
【解析】
句意：我可以直呼你的名字吗？是的，你可以。A选项will表示将会，B选项could一般用于疑问句表委婉语气，C选项may在表示允许的情况下表示可以，you may可替换you can。D选项might表示不是完全的肯定，在此处与句意不符合。故答案为C。
13．C
解析：C
【解析】
【分析】
【详解】
句意：一整天都在下雨，因此我不得不待在家里。
考查情态动词。can’t不能够，has to不得不，三单形式；have to不得不。根据句意可知天下雨，所以不得不待在家里，have to符合题意，且I是第一人称，故用have to。故选C。14．D
解析：D
【解析】
试题分析：此题重点考查被动语态，由于主语是动作的承受者，该句要用被动语态，排除A、C；根据句意：“每天一定要浇花，否则他们会死掉”B答案语气太委婉，因此要用must be+过去分词，故选D
考点：含情态动词的被动语态
点评：该题考查被动语态，做题时首先分析题干的主语是动作的执行者还是动作的承受者，若是动作的承受者就要用被动语态，特别要主语被动语态的结构，be+动词的过去分词
15．C
解析：C
【解析】
句意：每个人都应该对父母有礼貌。A. could可能； B. may也许； C. should应该；表示按理应当； D. can能够。根据句意故选C。
16．C
解析：C
【解析】
【分析】
【详解】
句意：——我听说他们去年冬天在山里滑冰。——这可能不是真的，因为那里几乎没有雪。may not be可能不是，表示现在的推测；won’t be将不是，表示将来；couldn’t be可能不是，表示过去；will be将是，表示将来。根据was可知此处表示过去，故选C。17．C
解析：C
【解析】
句意：——Mike明天会来时尚秀吗？——我不确定。他也许不会来。must一定，必须，表示有把握的推测；can可以，能够，表示能力；may也许，可能，表示没有把握的推测；should应该，表示建议。根据I’m not sure.可知此处表示没有把握的推测，故用情态动词may，故选C。
18．C
解析：C
【解析】
【分析】
【详解】
句意：——妈妈，我已经签了一个未来快递的大箱子。里面有什么？——我不确定。可能是你哥哥送的礼物。
考查情态动词。need需要；must必须；may可能；will将会；根据句意理解及前句I’m not sure.可知，这里是对不太确定的事情进行推测，英语中可能性不大的推测用may，故选C。
【点睛】
英语中情态动词有两种用法。一种是本身用法，还有一种是推测用法，表示推测用法时，常用的是must，can和may。must表示推测或推断时，其语气最为肯定，意为“一定”；can 表示推测用法时，常用于否定句和疑问句，多用否定形式，can’t意为“不可能”；may表示推测用法时，多用于肯定句，表示不太确定的可能性的推测，意为“可能，也许”；做题要稍加留意。
19．A
解析：A
【解析】
【分析】
【详解】
句意：——我必须现在睡觉吗？——不，你不需要。
考查情态动词。needn’t不需要；mustn’t不允许，禁止；can’t不能；may not可能不；根据句意理解可知，问句中用的是情态动词must，而must的否定回答是needn’t或者don’t have to，这里用的是needn’t，故选A。
20．D

（1）现在时：无区别，但后者不常用。 （2）完成时;can没有完成时，此时要用have（has,had）been able to。 （3）将来时：can没有将来时，要用will be able to。 （4）过去时：could表示一般能力，was/were able to 表示在具体场合通过努力成功做成某事的能力。 二、may 和might 1、may的用法 （1）表示询问或说明一件事可不可以做。 （2）表示一件事或许会发生或某种情况可能会存在，通常用在肯定句和否定句中。 注意：表示可能性时，can’t语气强，表示“不可能”，may not语气弱，表示“可能不”。 2、might的用法 （1）表示询问或允许，指的是过去时间。 （2）表示可能发生的事，可以指过去时间，也可以指现在时间，语气更加不肯定，可能性比may小一些。 3、may与might的特殊用法 （1）“may+主语+动词原形”表示祝愿。 （2）“may/ might well+动词原形”表示（完全）能，很可能。 （3）“may/ might as well+动词原形”表示最好，满可以，倒不如。 （4）may be 是“情态动词+系动词be”结构，表示“可能有，可能在”，否定式为may not be。 maybe是一个词，为副词，意为“大概，或许，可能”，在句中作状语。
