Question

--Must I give the dictionary back to the library now?

--No, you ________. You can ________ it for another two weeks.

1. A.
   needn't, borrow
2. B.
   needn't, keep
3. C.
   mustn't, lend
4. D.
   mustn't, keep

Answer 1

B
考查情态动词和动词。句意为：----我必须现在把词典归还给图书馆吗？----不，你不必。你可以再借两周。作为must引导的疑问句的否定回答应该用needn't表示“不必”，介词for出现之后句子的谓语动词应该用延续性动词，borrow是一个短暂性动词，它相应的延续性动词应该用keep。因此选B。A项干扰性最强。
