答案 B
解析 3.I should not have laughed if I________you were serious.(2017·江苏,30)
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。
4.—Why are your eyes so red?You________have slept well last night.
—Yeah,I stayed up late writing a report.(2017·四川,5)
A.can’t
B.mustn’t
C.needn’t D.won’t
答案 A
解析 5.My mom suggests that we ________ eat out for a change this weekend.(2017·陕西,12)
A.should
B.might
C.could D.would
答案 A
解析 句意为:母亲提议这个周末出去吃饭换换口味。suggest(建议)接宾语从句时谓语动词用(should)do。
6.Since nobody gave him any help,he ________ have done the research on his own.(2017·大纲全国,26)
A.can
B.must
C.would
D.need
答案 B
解析 7.If we________a table earlier,we wouldn’t be standing here in a queue.(2017·北京,34)
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.(2017·北京,35)
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。
9.Harry is feeling uncomfortable.He________too much at the party last night.(2017·辽宁,31)
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.(2017·天津,9)
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.
(2017·天津,14)
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.(2017·湖南,32)
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。
13.I ________ myself more—it was a perfect day.(2017·浙江,3)
A.shouldn’t have enjoyed
B.needn’t have enjoyed
C.wouldn’t have enjoyed
D.couldn’t have enjoyed
答案 D
解析 句意为:我那时玩得再高兴不过了——那真是完美的一天。couldn’t have done不可能做过。此处用not和比较级连用表达最高级的含义,意为“从未比这更高兴过”。故选D项。
14.Eye doctors recommend that a child’s first eye exam ________ at the age of six months old.(2017·浙江,8)
A.was
B.be
C.were D.is
答案 B
解析 recommend建议,其后常接that 引导的宾语从句,而宾语从句中要用sb.should do或者sth.should be done的形式,should常可省略。 故本题应选B项。
15.—Do you think George has passed the driving test?
—No.If so,he ________ his car to our college yesterday.(2017·福建,30)
A.would drive
B.drove
C.would have driven
D.had driven
答案 C
解析 句意为:——你认为George已经通过驾照考试了吗?——没有。如果通过的话,昨天他就会开车来我们的大学了。本题表达的是对过去事实的假设,句子结构为:If...had done...,...would(might,could,should) have done...。
16.When I was a child,I ________ watch TV whenever I wanted to.(2017·江西,29)
A.should
B.could
C.must
D.need
答案 B
解析 本题考查情态动词。should应该;could能够,可以;must必须;need需要。句意为:当我还是个孩子的时候,我想看电视的时候就可以看。根据句意可知,B项符合题意。
17.—It rained cats and dogs this morning.I’m glad we took an umbrella.
—Yeah,we would have got wet all over if we ________.(2017·重庆,29)
A.hadn’t
B.haven’t
C.didn’t D.don’t
答案 A
解析 考查虚拟语气。根据第一句可知,下雨、带伞都是发生在过去的事情,故第二句“如果我们没带伞的话,全身都会淋湿的”这一情景是与过去事实相反的假设,故if条件句用过去完成时,主句用“would/should/might/could+have done”。
18.I ________ use a clock to wake me up because at six o’clock each morning the train comes by my house.(2017·新课标全国,30)
A.couldn’t
B.mustn’t
C.shouldn’t
D.needn’t
答案 D
解析 根据后面的because引导的原因状语从句的内容可知选D项,即“因为每天早晨六点钟那列火车都经过我家,所以没有必要用闹钟来叫醒我”。couldn’t不能;mustn’t禁止;shouldn’t不应该;needn’t不必,不需要。
19.Grace doesn’t want to move to New York because she thinks if she________there,she wouldn’t be able to see her parents very often.
(2017·安徽,31)
A.lives
B.would live
C.has lived
D.were to live
答案 D
解析 句意为:格雷斯不想搬到纽约去,因为她认为,如果她住在那里,她就不能经常看见她的父母了。这是与将来情况相反的虚拟条件句。由主句知此处是对“未来”情况的虚拟。if引导的虚拟条件句中表示与将来的事实相反时可使用过去式、“should+v.”或“were to+v.”的形式,故选D项。
20.—Happy birthday!
—Thank you!It’s the best present I________for.(2017·江苏,35)
A.should have wished
B.must have wished
C.may have wished
D.could have wished
答案 D
解析 A项意为“本应该期望而实际上并非如此”;B项意为“一定期望”;C项意为“也许期望”;D项意为“能够期望”。句意为:——生日快乐!——谢谢你!这是我能期望的最好的礼物了。根据句意可知,应选D项。
