参考答案与试题解析
一、Exercises：
1．【解答】答案：B．考查情态动词．根据句意：你不会打棒球吗？不，　我会打．本句是反义疑问句，否定回答No， 后跟否定形式can't．英语中回答否定疑问句或反义疑问句陈述部分是否定形式的这类问题时，要注意不要受汉语的影响． 是按事实来回答的，只要事实是肯定的，就用Yes，事实是否定的就用No．前后一致．所以B选项符合．
故选：B．
2．【解答】答案：A．考查情态动词．根据句意："这周我必须交报纸吗？""不，你不必交，下个星期你就可以交了．"must引导的一般疑问句，否定回答用needn't， may表示许可．所以A选项符合．
故选：A．
3．【解答】答案：D．根据第一句话可知讨论是过去的事情，排除AB；must+have done不能用于否定句；couldn't have done是对过去的否定推测，意为"过去不可能做了某事"符合句意．
故选：D．
4．【解答】答案：C．must一定（肯定推测）；need需要；should应该（说话人按照经验进行主观判断）；could可能．根据句意可知这句话说话人根据现在的时间主观判断的结果．故选C．
5．【解答】答案：A．考查情态动词．根据句意：﹣﹣打扰一下，我可以把杂志从阅览室带出来吗？﹣﹣不，你不能．must一定，必须；would将会；may可以；need需要．根据I take the magazine out of the reading room，可知在这里句子表示一种请求或许可，一般用may引导，表示可以．mustn't 表示禁止，符合句意．
故选：A．
6．【解答】答案：A．考查情态动词．根据句意：这是老板给秘书的许诺，意为"．如果你干得出色，我会给你加薪的．"shall 和第二人称连用表示"许诺"，不用would．
故选：A．
7．【解答】答案：C．考查情态动词．根据句意：我们唱首歌，好吗？let's翻译成"咱们"，包括说话人和听话人，反义疑问句用shall we．
故选：C．
8．【解答】答案：D．考查情态动词．根据句意："你必须这么快就走吗？""不，我还没必要走．"．must是情态动词"必须"，引导的一般疑问句，否定回答用needn't．
故选：D．
9．【解答】答案A．
B项"must have taken it 过去一定拿走了它"表示对过去情况的推测；C项"might take it 可能拿走了它"表示对现在情况的推测；D项"should take it 应该拿走了它"表示对现在情况的推测；A项"could have taken it 可能已经拿走了它"表示对过去情况的推测；根据前后句的语境可知，从书店里借书是过去的动作，谁过去可能拿走了我从书店里借来的书呢？因此A项符合语境，故选A．
10．【解答】答案：A．考查情态动词．根据句意：他们去听课了，但课被推迟了．哦，所以他们不必去了．根据对话可以看出是过去时的句子，不必要做某事是needn't have done． should have done本来应该做没做；mustn't have done是禁止做；don't need to go 是现在时态．
故选：A．
11．【解答】A
12．【解答】答案：C．考查情态动词．根据句意："那不是汤姆在打篮球吗？""不可能，他昨天从梯子上摔下来，受了重伤．"．根据后文句子他昨天从梯子上摔下来，受了重伤．可以推断一定不是他，这是对于过去的有把握的否定推测，应该用情态动词couldn't或者can't．
故选：C．
13．【解答】答案：D．考查情态动词．句意："他需要走吗？"是的，他必须走．" need引导的一般疑问句，肯定回答用must，否定回答用needn't，本句是肯定回答，所以用must．
故选：D．
14．【解答】本题考查反义问句．根据句意和结构可知这里使用祈使句，祈使句的反义问句用will you？这是固定搭配．
故选：B．
15．【解答】答案：C 考查现在完成时．根据句意可知表示几天前就应该写完，所以要用现在完成时．ought to have done sth．意为"原本应该做某事（但却没做）"．
故选：C．
16．【解答】答案：C．考查情态动词．句意：她一天做的工作比她哥哥三天做的多．can表示一种能力，他哥哥干了三天的能力；could是can的过去时，本句是过去时态的句子，所以C 正确．
故选：C．
17．【解答】答案：A 考查情态动词．need作为实意动词"需要"是，否定结构为助动词+not+need+to；作为情态动词式结构为need't do；所以排除B；mustn't表示禁止，在这儿不合适，所以排除C；D项没有这个结构．
故选：A．
18．【解答】答案：D．考查情态动词．句意：明天是星期六，我不必早起．need 是情态动词"有必要"否定是needn't do；如果用做实意动词则用don't need to do．所以D选项符合．
故选：D．
19．【解答】答案：D．考查情态动词．句意：你在作文中犯了许多拼写错误，写完后你一定没有检查它．根据前文犯的错误可以判断一定没有检查，是对过去的有把握的否定推测，所以用can't have done结构．
故选：D．
20．【解答】答案：B．考查情态动词．句意：威尔逊小姐不在办公室，所以她一定在一个电脑室工作．根据前一句判断现在不在办公室，所以后文是对现在的肯定推测，所以用must be working．
故选：B．
二、NMET
21．【解答】答案：A．
本句中使用can't表达缺乏某种能力，是针对计算机来说的，couldn't是can't的过去式，主要是用来对过去的事情进行说明；may not意为可能不，是语气上比较委婉的一种猜测；might not是may not的过去式，许多时候不表示过去，仅仅是语气上的委婉；故选A
22．【解答】答案：B．考查情态动词．句意：珍妮本该信守诺言的，我想知道她为什么改变主意．由"我不知道他为何改变了主意"推知Janny本应该恪守诺言，但却没有．should have done本来应该做而没有做，表示责备．must have done是对过去的肯定推测；would have done指过去应该做．所以B选项符合句意．
故选：B．
23．【解答】本题考查情态动词+have done的结构．根据句意和 but we went to the concert instead可知用should have done表示"过去本应该做某事而没有"．A项是过去一定做了；BD都表示现在情况，和last night不符．
故选：C．
24．【解答】答案：A．考查情态动词．句意：我可以用一下你的电话吗？﹣是的，当然可以．can"能够"；will"乐意"；must"必须"；should"理应，应该"．
故选：A．
25．【解答】答案：A ought not to have done＝should not have done 意思是：过去本不该做（事实上却做了），表示责备的语气．根据后半句的时态，告诉秘密的动作又发生在过去，因此应用完成式，即在情态动词ought to后用have done的形式，所以选择A．
故选：A．
26．【解答】答案 B．
分析句子上下文语境可知，由"he was sent to the hospital immediately"可知，他过去事实上是吃了那食物，因此是一个与过去事实相反的虚拟语气，从句中使用过去完成时"had+过去分词"，主句用情态动词"would/could/should/might+have+done"，短语"sb be warned 某人被警告"，因此B项符合语境，
故选：B．
27．【解答】考查情态动词．must必须；may可能；can能够；could是can的过去式，由后句的"he isn't very sure"可知，前句表示把握性不大的肯定，只有B项符合题意．
故选：B．
28．【解答】答案：C 考查情态动词+have done结构．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"表示"本应该做而未做"．
故选：C．
29．【解答】答案：C
本题考查的是if条件句中的虚拟语气．表示对已发生事情的假设，故用过去完成时．结构是：从句中 使用had done，主句中使用would have done．
故选：C．
30．【解答】答案：A．
根据后面的句子I've told him already可知，再告诉他已经没有意义了，所以用needn't；故选A．wouldn't表示过去不会做，mustn't千万不能；shouldn't不应该．
31．【解答】答案：C．
分析句子的意思可知，铅笔像是断了指的是现在的状况，说明是与现在事实的一种虚拟，所以be动词要用were；
故选：C．
32．【解答】答案：D 句意表达的是与事实相反的假设，要用虚拟；对现在的虚拟，要用情态动词加动词原形来构成；虚拟语气中不能用will，故选D．
33．【解答】答案A 本题考查虚拟语气． 根据就本题题干是对过去发生的事情的虚拟． may/might have done 都可以表示对过去的事情进行肯定的推测，这里表达的是与过去事实相反的虚拟语气，只能用might+ have done．
故选：A．
34．【解答】答案：B．
mustn't表示禁止的意思，此处强调玩刀的危险性，后面的句子表示可能会出现的情况，用may表示一种潜在的可能；故选B．
35．【解答】答案：D
考查情态动词 could和was able to的区别．could表示有某种能力；was able to表示经过努力能够做到，强调成功．根据语境可知，强调成功地逃出，
故选：D．
36．【解答】答案：B．can能够；should应该；might可能；need需要，根据上下文语境可知这是说话人根据经验主观推测的可能性．用should．故选B．
37．【解答】本题考查情态动词的完成式．根据句意可知表示过去的虚拟，用情态动词+have done，排除BC．这里用could have done表虚拟，意为"本来能够做…（而事实上没做成）"，must have done过去一定做了某事．
故选：A．
38．【解答】答案是B．本题考查情态动词辨析；mustn't禁止；can't不能；不可能；needn't不必；won't不会；根据下文"我哥哥要来看我"推断我"不能"留下来吃晚饭，所以答案选择B．
39．【解答】根据I'm not sure可知，这是一种不确定的语气，所以用might来表示一种委婉的决定．
故选：D．
40．【解答】答案是B．本题考查情态动词辨析；should应该；can能够；（表示许可）可以；must必须；will会；根据语境和常识判断，包"可以"在行李暂存处存放，所以答案选择B．
