D。“couldnt have+过去分词”表示对过去情况的推测。既然小汽车上“已有五人”，且是“设法”才把你带去的，如此拥挤，旅途当然“不可能”舒服。3. C。nearly 暗示“时间不早了”，Jack“按理应当(should)随时(at any moment)”都有可能到达这里。must 语气过强；can 一般不用于肯定推测；need 意义不通，也不用于肯定句。4. B。mustnt(不许、千万不)表示禁止。may 表示可能性。句意为“你千万不要玩刀子，可能会弄伤自己的”。5. D。表示过去具体某次“能够”做成某事只能用 was / were able to 而不用could。6. B。should 表示按理应当，大概。can 一般不用于肯定推测；用 might 语气太不肯定，顾客可能走掉。 7. A。could have done 表示本可以做但却没有做的事。句意为“你本来可以住在 Barbara 那儿的”；而 must have done 只表示有把握的肯定推测，这与前面具有疑问语气的 Oh, did you?不符。8. D。语境明显提示“我可能(might)要去听音乐会” 9. B。表示轻微的责备，句意为“我真的好担心你啊。你当时本不该不说一声就离开家的”。10. D。由“他自己喜欢开车”这一习惯推断，“他可能不会(may not)坐火车来”。can not“不可能”，语气太肯定。11. B。can 表示“可以”。should(应该), must(必须), will(愿意)均不符合语境。12. D。dare 作行为动词时,一般接 to do
