C 解析：根据because引导的原因状语从句可知此处表示：不能买东西。cant 意为“不能”，符合句意。mustnt 意为：禁止，不许；neednt 意为：不必要；shouldnt 意为：不应该。3. D 解析：句意：我今天早上在会议室没有
16、看到她。她不可能在会议上讲话。couldnt have done sth. 表示对过去的情况进行推测，意为“过去不可能发生过某事”。4. A 解析：根据下文的 will be 可知，“他考试又不及格”是将来可能发生的事，用情态动词might 表示可能。B、D都表示对过去发生的事情的推测，不符合句意；should “应该”也与句意不符。5. D 解析：从时间上看，由于是昨天没来开会，所以推测“她生病”也是在昨天，故排除A和C。从语境上看，既然上文说 Im not so sure，那么说明说话者对自己的推测没有很大把握，故选D。6. C 解析：根据上文的过去时态可知，此句谈的是过去的事。could
17、 have done 表示“本来能够做某事，但事实上未做”，符合句意。7. C 解析：could have done sth. 结构在此表示责备，指过去本来可以做某事但实际上未做。第二空陈述的是过去的事实，应用was wasted。8. B 解析：根据下文的Ill phone the airport and find it out 可知，说话人对自己的推测没有很大把握，故选 might。must语气太强，不合语境；can 表推测，通常不用于肯定陈述句中。9. D 解析：既然“通行证现在不在口袋里”，那么它“掉出去”应发生在过去。must have done “肯定做过某事”；should ha
18、ve done “应该做某事”，根据句意，应选D项。10. A 解析：根据Dont be so sure 可知前面一空应填must。第二空填的could表示推测，虽为过去式形式，但表示现在的意义，语气较委婉，可以用于肯定陈述句中。11. B 解析：should have done“本来应该做某事，结果未做”，此处含有责备之意。12. B 解析：句意：我昨天给你打电话了，一位女士接的电话，但是我没有听出她的声音。噢，她肯定是我姨Jean。表示对过去情况的肯定推测，应用“情态动词+完成时”。注意can表示推测时通常不用于肯定陈述句。13. B 解析：表示过去可能发生而实际上未发生的事，用might
19、 have done。句意：汽车差点碰到我，我可能会被撞死的。14. A 解析：考查情态动词。句意：我的手机不见了，会是谁把它拿走了呢? 此处could have done表示“可能做过某事”，用于否定和疑问句中。should have done表示“本来应该做某事（但实际上并没有做）”；must have done表示“一定做了某事”；might have done表示“也许做了某事”，用于肯定句中。15. C 解析：mustnt 表示“禁止，不许”。16. B 解析：由主句中谓语可判断，表示的是与过去事实相反的情况，所以虚拟条件句中的谓语应用过去完成时，Had the captain be
20、en = If the captain had been。17. B 解析：考查虚拟语气。句意：我数学考试不及格真是太糟糕了，要是我之前努力学习就好了。if only后面的从句要用虚拟语气，从语境可知此处是对过去的情况的一种虚拟，所以谓语动词要用过去完成时。故选B。18. C 解析：考查虚拟语气。suggest作“建议”讲时，后面的宾语从句中的谓语动词应该用“should+动词原形”，should可以省略。19. C 解析：考查虚拟语气。答句句意：是的，否则她就不会在比赛中获得一等奖了。此处表示的是与过去事实相反的虚拟语气。20. C 解析：would rather后接从句时，从句若表示现在或
21、将来，从句中的谓语要用一般过去时；若从句表示过去，其谓语用过去完成时。根据语境可知，此处是表示“我希望你们（明早）不要早出发”。故选C。21. A 解析：根据句子结构可以知道，该题含if引导的条件状语从句。分析句意，该句表示一种假设，从句中的动作表示与过去事实相反，主句的动作是在将来发生，即表示与将来事实相反，故从句的谓语动词用had done，主句用would（could, might）动词原形。22. C 解析：在It is/was urgent that. . . 句型中，that引导的从句中谓语动词应用“should+动词原形”形式，should可以省略。类似的形容词还有necessa
22、ry, advisable, desirable, vital等。23. C 解析：考查虚拟语气。句意：多遗憾！如果我能赶上那班航班，现在我就正飞越太平洋了。从句是对过去发生的动作的虚拟，主句是对现在正在发生的动作的虚拟，故谓语动词用would be doing。24. D 解析：考查情态动词。句意：这项任务很有挑战性，要求很高。你认为谁能完成？我的搭档能试一下吗？我认为她是做这项工作最合适的人选。shall 在疑问句中用于第一、三人称，表示说话人征询对方的意见或请求指示。25. D 解析：考查情态动词。句意：你非要在她忙着做晚饭的时候用这么烦人的问题来打扰她吗？对不起，我不该在那个时候那么做
23、的。must 表示“偏偏，非要”，should not have done sth. “本不应该做某事，但事实上已经做了”。26. A 解析：考查情态动词。句意：那支足球队这个赛季一直做得很好，因此他们按理该获得冠军的。should在这里意为“按理说，估计应该”，需要有一种逻辑推测。句中的has been doing well表明了一直做得很好，故后面应该会赢得冠军。27. B 解析：考查虚拟语气。句意：谢谢你上周的努力工作。没有你我想我们不会完成它的。without引出虚拟语气，这里是对过去的情况进行虚拟。28. A 解析：考查情态动词。由第一句的took可知事情发生在过去，故第二句应是对过去进行推测。再由more comfortable and safer知could have taken符合，意为“本可以乘九点钟的火车”。29. D 解析：句意：专家们认为常常侵袭人们的大多数疾病有时能通过预防措施得以避免。根据句意可知，此处表示一种客观可能性，故选D。can用于肯定句时，可表示客观或理论上的可能性，意思是“有时会”。30. A 解析：考查动词时态和虚拟语气。would have helped you表示与过去事实相反的虚拟语气。but后面是表示事实的句子。答案选A，表过去的实际情况。句意：我本可以帮助你的，但我整个星期确实很忙。 5
