解析 3.I should not have laughed if I________you were serious.(2013·江蘇，30)
A.thought B.would think
C.had thought D.have thought
答案 C
解析 考查虛擬語氣。句意為：如果我當(dāng)時(shí)想到你是認(rèn)真的，我就不會(huì)笑了。由句意知，此句是與過去事實(shí)相反的虛擬語氣，故從句結(jié)構(gòu)為had done。
4.—Why are your eyes so red?You________have slept well last night.
—Yeah，I stayed up late writing a report.(2013·四川，5)
A.can’t B.mustn’t

A.should B.might
C.could D.would
答案 A
解析 句意為：母親提議這個(gè)周末出去吃飯換換口味。suggest(建議)接賓語從句時(shí)謂語動(dòng)詞用(should)do。
6.Since nobody gave him any help，he ________ have done the research on his own.(2013·大綱全國，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.(2013·北京，34)
A.have booked B.booked
C.book D.had booked
答案 D
解析 考查虛擬語氣。句意為：如果早些預(yù)訂飯桌，我們現(xiàn)在就不會(huì)站在這兒排隊(duì)了。if從句是對(duì)過去情況的假設(shè)，故用過去完成時(shí)態(tài)。
8.—You needn’t take an umbrella.It isn’t going to rain.
—Well，I don’t know.It________do.(2013·北京，35)
A.might B.need
C.would D.should
答案 A
解析 考查情態(tài)動(dòng)詞用法。句意為：——你不必帶傘。天不會(huì)下雨?！也恢?，可能會(huì)下雨吧。might“可能”，表推測，且可能性較小。
9.Harry is feeling uncomfortable.He________too much at the party last night.(2013·遼寧，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.(2013·天津，9)
A.could B.must
C.dare D.need
答案 A
解析 考查情態(tài)動(dòng)詞。句意為：沒人比他更慷慨;他有一顆金子般的心。“No one could be more generous”是否定詞和比較級(jí)連用，表達(dá)高級(jí)含義，A項(xiàng)could可以在否定句中表示推測，為正確答案。B項(xiàng)表推測，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. (2013·天津，14)
A.will be B.would be
C.has been D.would have been
答案 B
解析 考查虛擬語氣。句意為：如果以前他花更多時(shí)間練習(xí)說英語的話，現(xiàn)在他英語就會(huì)說得好多了。由從句中的had spent可知從句與過去事實(shí)相反;由主句中的now可知主句與現(xiàn)在事實(shí)相反，故用would be。本題實(shí)際上是考查錯(cuò)綜時(shí)間的虛擬語氣。
12.He________sleep，although he tried to，when he got on such a hunt for an idea until he had caught it.(2013·湖南，32)
A.wouldn’t B.shouldn’t
C.couldn’t D.mustn’t
答案 C
解析 考查情態(tài)動(dòng)詞的辨析。wouldn’t不會(huì);shouldn’t不應(yīng)該;couldn’t不能;mustn’t禁止。根據(jù)語境可知，他顯然是“不能”入睡，根據(jù)句中的although he tried to可知這里說的是過去的事情，所以用cannot的過去式。
13.I ________ myself more—it was a perfect day.(2013·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 句意為：我那時(shí)玩得再高興不過了——那真是完美的一天。couldn’t have done不可能做過。此處用not和比較級(jí)連用表達(dá)高級(jí)的含義，意為“從未比這更高興過”。故選D項(xiàng)。
14.Eye doctors recommend that a child’s first eye exam ________ at the age of six months old.(2013·浙江，8)
A.was B.be
C.were D.is
答案 B
解析 recommend建議，其后常接that 引導(dǎo)的賓語從句，而賓語從句中要用sb.should do或者sth.should be done的形式，should?？墒÷浴?故本題應(yīng)選B項(xiàng)。
15.—Do you think George has passed the driving test?
—No.If so，he ________ his car to our college yesterday.(2013·福建，30)
A.would drive B.drove
C.would have driven D.had driven
答案 C
解析 句意為：——你認(rèn)為George已經(jīng)通過駕照考試了嗎?——沒有。如果通過的話，昨天他就會(huì)開車來我們的大學(xué)了。本題表達(dá)的是對(duì)過去事實(shí)的假設(shè)，句子結(jié)構(gòu)為：If...had done...，...would(might，could，should) have done...。
16.When I was a child，I ________ watch TV whenever I wanted to.(2013·江西，29)
A.should B.could
C.must D.need
答案 B
解析 本題考查情態(tài)動(dòng)詞。should應(yīng)該;could能夠，可以;must必須;need需要。句意為：當(dāng)我還是個(gè)孩子的時(shí)候，我想看電視的時(shí)候就可以看。根據(jù)句意可知，B項(xiàng)符合題意。
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 ________.(2013·重慶，29)
A.hadn’t B.haven’t
C.didn’t D.don’t
答案 A
解析 考查虛擬語氣。根據(jù)第一句可知，下雨、帶傘都是發(fā)生在過去的事情，故第二句“如果我們沒帶傘的話，全身都會(huì)淋濕的”這一情景是與過去事實(shí)相反的假設(shè)，故if條件句用過去完成時(shí)，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.(2012·新課標(biāo)全國，30)
A.couldn’t B.mustn’t
C.shouldn’t D.needn’t
答案 D
解析 根據(jù)后面的because引導(dǎo)的原因狀語從句的內(nèi)容可知選D項(xiàng)，即“因?yàn)槊刻煸绯苛c(diǎn)鐘那列火車都經(jīng)過我家，所以沒有必要用鬧鐘來叫醒我”。couldn’t不能;mustn’t禁止;shouldn’t不應(yīng)該;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. (2012·安徽，31)
A.lives B.would live
C.has lived D.were to live
答案 D
解析 句意為：格雷斯不想搬到紐約去，因?yàn)樗J(rèn)為，如果她住在那里，她就不能經(jīng)常看見她的父母了。這是與將來情況相反的虛擬條件句。由主句知此處是對(duì)“未來”情況的虛擬。if引導(dǎo)的虛擬條件句中表示與將來的事實(shí)相反時(shí)可使用過去式、“should+v.”或“were to+v.”的形式，故選D項(xiàng)。
20.—Happy birthday!
—Thank you!It’s the best present I________for.(2012·江蘇，35)
A.should have wished
B.must have wished
C.may have wished
D.could have wished
答案 D
解析 A項(xiàng)意為“本應(yīng)該期望而實(shí)際上并非如此”;B項(xiàng)意為“一定期望”;C項(xiàng)意為“也許期望”;D項(xiàng)意為“能夠期望”。句意為：——生日快樂!——謝謝你!這是我能期望的好的禮物了。根據(jù)句意可知，應(yīng)選D項(xiàng)。
