Ⅱ.单项填空
1．I ________ through that bitter period without your generous help.
A. couldn't have gone B. didn't go
C. wouldn't go D. hadn't gone
答案与解析　A　考查虚拟语气的用法。句意：没有你的慷慨挂念，我是不行能度过那段苦痛的时期的。that bitter period表示过去的时间，对过去的虚拟语气用主语＋should/would/could/might＋have done表达，故选A项。
2．It ________ be the postman at the door. It's only six o'clock.
A. mustn't B. can't
C. won't D. needn't
答案与解析　B　考查情态动词的用法。句意：不行能是邮递员在门口，才六点钟呢。mustn't“禁止，不允许”； can't“不行能”； won't“不情愿，就是不，偏不”； needn't“不需要”。依据后一句中“现在仅仅是六点”， only一词确定语气猛烈，前一句为门外的绝不行能是邮递员。故选B项。
3．— Happy birthday!
— Thank you! It's the best present I ________ for.
A. should have wished B. must have wished
C. may have wished D. could have wished
答案与解析　D　考查情态动词＋完成式。A项意为“本应当期望而实际上并非如此”； B项意为“肯定期望”； C项意为“或许期望”； D项意为“可能期望”。句意：——生日欢快！——感谢你！这是我所能期望的最好的礼物了。依据句意可知，应选D项。
4．— I don't really like James. Why did you invite him?
— Don't worry. He ________ come. He said he wasn't certain what his plans were.
A. must not B. need not
C. would not D. might not
答案与解析　D　考查情态动词的用法。句意：——我真不宠爱詹姆斯。你为何请了他？——别担忧。他可能来不了。他说他的方案还没支配好。题干中的he wasn't certain说明他可能不来，也可能来，因此使用不完全否定might not。选D项。
5．As she's not here, I suppose she ________ home.
A. must go B. must have gone
C. might go D. might be going
答案与解析　B　must后接动词完成式表示对过去状况的确定推想，意为“肯定已经做了某事”。
