答案分析
1. C。“ought to / should have+过去分词”表示后悔当初该做但却没做某事。“…或许我本该把详细地址写给她的。”
2. D。“couldn’t have+过去分词”表示对过去状况的推断。既然小汽车上“已有五人”，且是“设法”才把你带去的，这样拥挤，旅途当然“不可能”舒服。
3. C。nearly 暗示“时间不早了”，Jack“按理应当随时”都大概到达这里。must 语气过强;can 一般不需要于一定推断;need 意义不通，也不需要于一定句。
4. B。mustn’t表示禁止。may 表示可能性。句意为“你千万不要玩刀子，或许会弄伤我们的”。
5. D。表示过去具体某次“可以”做成某事只可以用 was / were able to 而不需要could。
6. B。should 表示按理应当，大概。can 一般不需要于一定推断;用 might 语气太不愿定，客户可能走掉。
7. A。could have done 表示本可以做但却没做的事。句意为“你本来可以住在 Barbara 那儿的”;而 must have done 只表示有把握的一定推断，这与前面具备疑问语气的 Oh, did you?不符。
8. D。语境明显提示“我可能要去听音乐会” 。
9. B。表示轻微的责备，句意为“我真的好担忧你啊。你当时本不该不说一声就离开家的”。
10. D。由“他一个人喜欢开车”这一习惯判断，“他可能不会坐火车来”。can not“不可能”，语气太一定。
11. B。can 表示“可以”。should, must, will均不符合语境。
12. D。dare 作行为动词时,一般接 to do，但疑问式或否定式中 to 可以省略，此句有疑问口气。
13. A。would 表示过去的习惯。
14. D。在规章中告诫应考者，在收完所有试题前“需要”留在教室里。
15. A。can 在疑问句中，表示疑惑、怀疑，依据状况可译作“能、可以”等。
