[答案与解析]
1. D。本题考查would rather do…than do。句意为“我今晚宁愿呆在家里也不愿去看电影。”
2. C。本题考查情态动词的基本用法。shouldn’t意为“不应该”， can’t意为“不可能”；don’t have to意为“不必”；mustn’t意为“不可以”。根据句意“我要支付多少电话费？”“你不必。是免费的。”故答案为C。
3. A。dare作情态动词时，没有人称、数的变化，后接动词原形。故答案为A。句意为“他今天在闹情绪。没有人敢当面说那件事。”
4. B。以must开头的疑问句，否定回答用needn’t 或don’t have to. 故答案为B。
5. A。would表示过去的习惯或倾向性。句意为“安不富裕，但邻居有困难时她总会帮助他们。”
6. C。本题考查should用于It is a pity that句型。句意为“发生这种事情真是太遗憾了。”
7. B。通过情景对话考查情态动词的用法。答语中given more time= If I had been given more time, 因此，主句应该是I could have done it better.故答案为B。
8. B。由上句中的进行时态，可知答语中的时态用may+进行式，对正在发生的事情进行推测。意为“可能正在┅”“想必正在┅”。
9. D。will表示倾向性，否定式为won’t。句意为“门关不住了。最好让人修一下。”
10. B。本题考查情态动词的用法。前半句是说话人自己的观点“这个工程要全盘考虑”，用should；后半句是“有把握竣工”，用can表示能力。故答案为B。
11. B。根据前一句“那么年轻的女演员那么快嫁给了那么老的制片人”可知是对过去情况的推测，因此用情态动词+现在完成式。由句中的so soon可知后句“她不可能对他很了解”，因此用can’t have done 结构，故答案为 B。
12. C。由句中的just now可知是对过去事情的推测，因此用情态动词+现在完成式。排除A和D；must 表推测只能用在肯定句中，排除B；故答案为C。shouldn’t have done表示“本来不该做某事而实际做了”。
13. D。should 表示建议或劝告。句意为“准时到那儿对你来说很重要。你应该八点钟到那儿。”
14. B。用may表示请求允许。句意为“我明天起一天假，可以吗？”
15. A。上句中说话者说他要食素。由答语中后一句“你将会很饿的”来推断前一句是肯定的推断，因此用must，意为“必定；非常可能”。
16. B。本题考查情态动词用法区别。must意为“准是、一定”； can意为“能够”；will 意为“会，愿意”； may 意为“可能”。根据句意“但还没有确定”可知“Peter今晚可能来”，因此用may。故答案为B。
17. D。根据上句“你没邀请Bill吗？”可知是对过去事情的推测，因此用情态动词+现在完成式。排除A和C；must 表推测只能用在肯定句中，排除B；故答案为D，意为“我应该邀请他吗？”
18. D。由答语中的“我打电话问一下”可知说话者对今晚是否有雾拿不准，因此用might表示可能性不大。
19. C。根据上句中的climbed可知第一空是对过去事情的推测，因此用情态动词+现在完成式，must have done意为“准是做了某事”；should have done意为“本来该做某事而实际未做”，均不符合题意；故应用may / might have done, 意为“可能”；第二空表示禁止，应用mustn’t, 句意为“下次你不需那样做了”。故答案为C。
20. A。句意为“外语例如英语特别有用，所以你再怎么努力也不过分”。can’t…not…意为“无论如何┅也不过分”。又如：We can’t b too careful of health. 我们无论如何注意健康也不算过分。
21. C。“你还记得我们什么时候去的北京吗？”“我现在不记得了，可能是去年夏天某个时候吧？”could have done是对过去事情的推测，意为“可能”，符合题意。故答案为C。
22. D。must表示与说话人愿望相反及不耐烦，意为“偏要”“偏偏”。句意为“太糟糕了。正当我们要去度假时车偏偏出毛病了。”
23. B。might as well意为“还是…的好；不妨”。句意为“既然我们不急，我们还是等公共汽车去车站吧。”
24. C。本题考查情态动词词义辨析。当与完成式连用时，couldn’t 意为“本来不能”； shouldn’t意为“本来不该”；needn’t意为“本来不需要”； mustn’t无此用法。根据句意“音乐会晚了十分钟。所以我不需要从家里一路跑到音乐厅。”故答案为C。
25. A。在表示能力时was / were able to 和 could可以通用，当表示经过努力或克服了困难之后做成了某事时用was / were able to。句意识说他尽管有很多次失败，但从没气馁，最终实现了他当冠军的梦想。故答案为A。
