答案解析
1.【解析】选C。考查情态动词表示推测。句意: ——玛丽的姐姐现在看上去非常漂亮。——但是她在整容前是非常丑陋的。你不会相信这事情。根据语境“前后丑、漂亮”的对比, 推知人们“不愿意; 不会”相信; wouldn’t意思为“不情愿”符合题意。
2.【解析】选C。考查情态动词表示推测。句意: ——史密斯先生在哪里? 我到处找不到他。——他不可能走远, 因为他的手机还在这里。根据语境“到处找不到他”推知是对过去情况的猜测, 故can’t have gone far意思为“不可能走远”符合语境。
3.【解析】选D。考查情态动词表示推测。句意: ——约翰昨天为什么没有参加比赛? ——他因为受伤严重肯定退出比赛了。由此处语境“受伤严重”推知对于“退出比赛”的推测语气比较强烈, 有“肯定……”之意, 并且是对过去情况的推测故用must+have done形式。
4.【解析】选A。考查情态动词的用法。句意: 你不应该休班, 这给其他所有的人都造成了负担。由句子语境分析, 句子谓语动作发生在过去, “过去不应该做某事”要用shouldn’t have done, 故选A。must 表示推测意义不可用于否定形式, 故B项不存在; couldn’t have done不可能做某事; wouldn’t have done过去不会做某事。
5. 【解析】选A。考查情态动词表推测。句意: 多浇一点水, 小树苗就不会死了。根据句意可知是对过去事情的推测。couldn’t have done指过去肯定不会做某事; needn’t have done表示没必要做某事但做了; shouldn’t have done表示本不应该做某事但做了。根据句意可知选A项。
6. 【解析】选C。考查情态动词表示推测。句意: 尽管Lily通常很随和, 但有时也相当讨厌。can意思为“有时会”符合题意。

止”, 故答案A合适。
9. 【解析】选B。考查情态动词表示请求。句意: ——史密斯先生, 汤姆在这里。他现在可以进来吗? ——噢, 是的。我一直等着他呢。根据语境“来了; 一直在等”推知“没有进来”, 此处“征求进来”的同意。shall用在一、三人称的句子中表示请求。
10. 【解析】选D。考查情态动词表示警告。句意: ——妈妈, 你为什么没有穿你的慢跑短裤呢? ——如果你非要知道的话, 我告诉你, 我的腿太瘦。根据语境“告诉了不穿慢跑短裤”的原因, 推知“非要; 一定”想知道的迫切心情, 故答案D合适。
11. 【解析】选C。考查情态动词表示警告。句意: ——戴维总是不上班。——告诉他如果他继续这种行为的话, 他要为此负责。shall用在二、三人称的陈述句中意思为“命令; 警告; 允许; 威胁”。根据语境此处为“警告”。

13. 【解析】选C。考查情态动词表示必要性。句意: ——凯特, 今天下午照顾好你的弟弟。——我一定要这样吗? 他的年龄还不足以照顾自己吗? 他现在已经12岁了。根据语境“大到可以照顾自己; 12岁”推知“不愿意去照顾弟弟”, 故意思为“非要; 一定”答案C合适。
14. 【解析】选D。考查情态动词表示必要性。句意: ——理想的团队领导者是什么样子? ——他应该是一个有责任心、有决心、有创造力的人。根据常识此处指领导人的素质, 故推知“应该具备……”, 答案D合适。

16.【解析】选C。考查情态动词+have done用法。句意: ——为什么昨天你没有去参加迈克的生日晚会? ——啊, 我本该去的, 但我忘记了。根据语境“我忘记了”推知“本该做……”, 故答案C合适。

20. 【解析】选C。考查混合型虚拟语气。句意: ——可惜的是你错过了这场音乐会。——我本想参加的, 但是我忙于准备一次工作面试。此处“想参加”但事实是没有参加, 为对过去情况相反的假设; 后面的主句则为真实句, 用了一般过去时。
21.【解析】选D。考查虚拟语气。句意: 如果我有足够的钱, 当价格不太高时, 我就买一辆车了。此处语气为对过去情况相反的假设, 事实是没有买, 价格现在也高, 故从句用had done; 主句用would have done形式, 答案D合适。
22.【解析】选B。考查虚拟语气。句意: 感谢你上周的辛勤工作。我想没有你的话, 我们就不可能完成。without you常用于表示虚拟语气的句子中, 主句根据情况用相应的虚拟语气形式。根据前文的语境可知without you相当于一个虚拟条件句if we hadn’t had your help, 表示与过去事实相反的虚拟语气, 故主句使用B项。
23.【解析】选D。考查情态动词+have done形式。句意: 由于原来是一个很小的家庭聚会, 我们不需要打扮得那么正式。根据“a small house party”推知“打扮正式”是“不需要”的, 此处为过去情况, 故答案D合适。
24.【解析】选A。考查情态动词表示推测。句意: 司机出事前或许喝了很多酒, 但是我不很确定。根据语境“不很确定”推知“或许”语气较弱。must意思为“一定; 必须”不符合语境。
【误区警示】本题不注意理解语境“but I’m not quite sure of that”, 句子语气把握不准确, 往往会误选B。本题主要考查学生对语境的理解, 通过语境把握语气, 从而得出猜测的可能性的大小。
25.【解析】选B。考查情态动词表示必要性。句意: ——现在我要告诉他时间表变了吗? ——恐怕你必须这样做, 以防他开会迟到。表示“必须”要用must。

情态动词与虚拟语气 【语法要点】 情态动词 所谓情态动词是指它含有一定的含义，可以表达某种感情和说话的语气，但是它不可以单独使用 作谓语动词。学习情态动词主要学习英语国家的语言习惯和表达法，特别是在口语中不要过分追求原理，更不要不根据说话场合而进行推理，编造出一些语法结构正确的中文式英语。 一、情态动词的类型 1.只作情态动词的有：must、can、could、may、might、ought to 2.既可作情态动词又可作实义动词的有：need、dare 3.既可作情态动词又可作助动词的有：shall、should、will、would 二、情态动词的特征 1.表示说话人的情感态度，不能单独作谓语，与行为动词或连系动词一起作谓语。 2.情态动词没有人称和数的变化，后接动词原形。 3.具有助动词的特征：可用来构成否定句、疑问句或简短答语。 三、情态动词的用法 1.表示能力 （1）表示现在的能力，用can 或be able to。表示一般的能力时多用can，表示“经过努力成功 的做成某事”用be able to。 （2）表示过去的能力，用could或was/were be able to。区别同上。 （3）表示将来的能力，用will be able to。 2.表示推测、可能性 （1）can 用在肯定句中表示客观的可能性，而不表示具体事情实际发生的可能性。 例如：Accidents can happy on such rainy days. （2）表示具体事情实际发生的可能性的情态动词，其表示可能性的层次如下表： 情态动词肯定式否定式疑问式 must 必定、必然、一定 will 很可能、大概不会、不该会,,吗？ would 可能性较will 小不会、不该（较won’t 弱）会,,吗？（较will 弱） should 应该会、理应（表示合乎理想的情况或结果） ought to 与should 同义 can 一定不会、不可能（否定推测）有可能吗？ could 可疑的可能不可能（与can’t 同义）有可能吗？（较can 弱）may 或许、可能、说不定可能不 might 或许、可能（较may 弱）可能不（较may not 弱） 注意→（1）may，must 常用于肯定句，一般不用于否定句和疑问句。 （2）can 常用于否定句，疑问句和感叹句中，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。

情态动词和虚拟语气 情态动词的用法要点 一、表能力 Can Am/is/are able to 表现在的能力 Will be able to 表将来的能力 could Was/were able to 表过去得能力 Could have+过去分词：表示过去有能力做但未做 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。 Accidents can happen on such rainy days.

This may not be done by him. He could be on his way home now. Can this be done by him? Mr Mush is on time for everything. How can it be that he was late for the opening ceremony? I didn’t hear the phone. I must have been asleep. ---Are you coming to Jeff’party? ---I’m not sure. I might go to the concert instead. (3) would, could, should, might 并不一定与过去时间有关，而表示可能性弱于它们相应的现在时形式。 This may/ might be done by him. (4)should 表推测时，表示确定或可能有的未来或期望，即合乎理想的情况或结果 He ought to/ should be here on time---he started early enough. We should arrive before dark. The roads should be less crowded today. 三、表示请求、允许、允诺 1.当对方是决策者时，你代表你（们）自己（I, we），或代表第三者（he she they）向对方（you）请示或提 出建议时用：
