學(xué)士學(xué)位英語考試詞匯練習(xí)及答案二十九

1. ____ you were busy, I wouldn’t have bothered you with my questions.

A.If I realized B. Had I realized

C.Did I have realized that D. As I realized

【答案】B 本題考察的是與過去事實(shí)相反的虛擬語氣.條件狀語從句謂語動(dòng)詞用had +過去分詞,主句謂語動(dòng)詞用,should/would/could/might +have + 過去分詞.當(dāng)省略if 時(shí),條件從句中的had 提前. 句意是“如果我意識(shí)到你這么忙,我就不拿我的這些問題來打擾你了.”

2. ___, I should ask them some questions.

A. Should they come to us B. If they come to us

C. Were they come to us D. Had they come to us

【答案】A 本題考查的是省略if的虛擬語氣的用法。從句中的助動(dòng)詞had, were, should等要移至主語之前。如果他們來到我們身邊，我會(huì)問他們一些問題。

3. Had the weather been good, the children ___ out for a walk.

A. had gone B. could have gone C. would go D. went

【答案】B。當(dāng)虛擬語氣中含有were, had, should, would等詞時(shí)， 可以省略if, 把這些詞放在主語之前。Should I meet her, I would tell her.萬一我見到他， 我會(huì)告訴他的。Were I in your position, I would do it better.如果我處在你的位置上， 我會(huì)做的更好。Had they made preparations, they would have succeeded.如果他們準(zhǔn)備了的話， 他們應(yīng)該能成功的。本句為和過去的事實(shí)相反的虛擬語氣，因此選B。

4. ___ today, he would get there for holiday.

A. Was he leaving B. Were he to leave C. Would he leave D. If he leaves

【答案】B。如果他今天走的話，他就在那里度假了。對(duì)將來的虛擬。

5. We ___ our lives had it not been for the policeman.

A. would have lost B. should lose C. might lose D. could have lost

【答案】A。要不是警察，我們都已經(jīng)沒命了。從句對(duì)過去，主句對(duì)現(xiàn)在。

6. He was very busy yesterday; otherwise he______ to the meeting.

A. would have come B. would come C. could come D. had come

【答案】A 本句考察虛擬語氣。“如果他不是很忙的話，昨天就去開會(huì)了”，事實(shí)是他沒有去開會(huì)，所以是與過去事實(shí)相反的假設(shè)，主句應(yīng)該用過去將來完成時(shí)，因此選A項(xiàng)would have come.

7. Without your help, we ____ so much.

A. didn’t achieve B. would not have achieved C. will not achieve D. don’t achieve

【答案】B 本題考察的是虛擬語氣. without your help = if you had not helped us,表示與過去事實(shí)相反,主句謂語動(dòng)詞用should/would/could/might + 動(dòng)詞原形.故選B. 句意是“如果不是你幫助我們,我們就不會(huì)取得這么大的成就.”

8. Something must have happened on their way here. Or they ___ by now.

A. should have arrived B. should arrive C. would have arrived D. would arrive

【答案】C。第一句是must+have +過去分詞的結(jié)構(gòu)，表示對(duì)過去事實(shí)的推測。The road is wet. It must have rained last night.路是濕的，昨晚上肯定下雨了。因此我們可以推斷：這是一個(gè)和過去的事實(shí)相反的虛擬語氣。should +have +過去分詞的結(jié)構(gòu)，表示對(duì)過去動(dòng)作的責(zé)備、批評(píng)。如：You should have gone over your lessons.你應(yīng)當(dāng)把功課復(fù)習(xí)好的。但是此句只是一個(gè)表示和過去的事實(shí)相反的虛擬句子，并沒有責(zé)備的意思。本句的意思是：“路上肯定出事了。否則，他們現(xiàn)在已經(jīng)到了。”因此正確答案應(yīng)該是C.

9. But for the rain, we ____ a nice holiday.

A. should have B. would have had C. would have D. will have had

【答案】B 這是含蓄條件句，表示“如果不……則我們已經(jīng)……了”，故選B。but for：如果不是因?yàn)?hellip;…，要不是……。句意為：如果不是因?yàn)橄掠?，我們本可以好好度假。Would have done 表示對(duì)過去事實(shí)的虛擬。

10. But for my classmates’ help, I ___the work in time.

A. did not finish B. could not finish

C. will not finish D. would not have finished

【答案】D 此句是含有含蓄條件句“but for my classmate's help"的句子.因此要選擇一個(gè)虛擬語氣的句子。因?yàn)槭呛瓦^去的事實(shí)相反,因此D為正確答案。本句的意思是：“要不是同學(xué)們的幫助.我是不會(huì)按時(shí)完成任務(wù)的

11. If you_____ that late movie last night, you wouldn’t be so sleepy.

A. hadn’t watched B. haven’t watched

C. wouldn’t have watched D. didn’t watch

【答案】A 此題考察虛擬語氣，假設(shè)“如果你昨晚沒看那場電影”，事實(shí)是看了，因此句意與過去事實(shí)相反，用過去完成時(shí)。

12. If he ___ to the teacher attentively, he ___ the answer to the problem now.

A. had listened, would have known B. listened, would know

C. listened, would have known D. had listened, would know

【答案】D。如果他認(rèn)真聽了課，他就會(huì)知道這個(gè)問題的答案了。錯(cuò)綜虛擬語氣，前半句對(duì)過去，后半句對(duì)現(xiàn)在。

13. ---- I thought you would come back tomorrow.

---- I would if I ___ to attend a meeting.

A. don’t have B. didn’t have C. will not have D. would not have

【答案】B。我以為你明天才回來呢。要是不用開會(huì)，我就明天回來了。If從句對(duì)現(xiàn)在虛擬。

14. Had you listened to the doctor, you _____ all right now.

A. are B. were C. would be D. would have been

【答案】C。如果你聽了醫(yī)生的話，你現(xiàn)在就已經(jīng)好了。前面對(duì)過去，后面對(duì)現(xiàn)在。

15. It is hard for me to imagine what I would be doing today if I ________ in love, at the age of seven, with the Melinda Cox Library in my hometown.

A. wouldn't have fallen B. had not fallen

C. should fall D. were to fall
