解析 3.I should not have laughed if I________you were serious.

A.thought B.would think

C.had thought D.have thought

答案 C

解析 考查虚拟语气。句意为：如果我当时想到你是认真的，我就不会笑了。由句意知，此句是与过去事实相反的虚拟语气，故从句结构为had done。

答案 A

5.My mom suggests that we ________ eat out for a change this weekend.

7.If we________a table earlier，we wouldn’t be standing here in a queue.

A.have booked B.booked

C.book D.had booked

答案 D

解析 考查虚拟语气。句意为：如果早些预订饭桌，我们现在就不会站在这儿排队了。if从句是对过去情况的假设，故用过去完成时态。

8.—You needn’t take an umbrella.It isn’t going to rain.

—Well，I don’t know.It________do.

A.might B.need

C.would D.should

答案 A

解析 考查情态动词用法。句意为：——你不必带伞。天不会下雨。——我不知道，可能会下雨吧。might“可能”，表推测，且可能性较小。

A.could drink B.should drink

C.would have drunk D.must have drunk

答案 D

解析 10.No one________ be more generous;he has a heart of gold.

A.could B.must

C.dare D.need

答案 A

解析 考查情态动词。句意为：没人比他更慷慨;他有一颗金子般的心。“No one could be more generous”是否定词和比较级连用，表达最高级含义，A项could可以在否定句中表示推测，为正确答案。B项表推测，只用在肯定句中;dare和need不符合句意。

11.If he had spent more time practising speaking English before，he________able to speak it much better now. 

A.will be B.would be

C.has been D.would have been

答案 B

解析 考查虚拟语气。句意为：如果以前他花更多时间练习说英语的话，现在他英语就会说得好多了。由从句中的had spent可知从句与过去事实相反;由主句中的now可知主句与现在事实相反，故用would be。本题实际上是考查错综时间的虚拟语气。

12.He________sleep，although he tried to，when he got on such a hunt for an idea until he had caught it.

A.wouldn’t B.shouldn’t

C.couldn’t D.mustn’t

答案 C

解析 考查情态动词的辨析。wouldn’t不会;shouldn’t不应该;couldn’t不能;mustn’t禁止。根据语境可知，他显然是“不能”入睡，根据句中的although he tried to可知这里说的是过去的事情，所以用cannot的过去式。
