距離全國英語六級考試還剩不到兩個月的時間了，童鞋們有木有已經開始緊張了呀~以下是yjbys網小編整理的關於英語六級虛擬語氣精選例題，供大家備考。
1. As usual, he put on a show as though his trip______ a great success.
A. had been B. has been C. were D. was
解析： though引導的與過去相反的虛擬。
2. Looking round the town, he felt as though he ______ away for ages.
A. has been B. was C. is D. had been
解析：是過去式，所以該句是由as though引導的與過去相反的虛擬。
3. John is so strongly built that he looks as if he ______ as elephant.
A. lifts B. is lifting C. lifted D. could lift
解析： if引導的與現在事實相反的虛擬。
4. He described the town as if he ______ it himself.
A. had seen B. has seen C. saw D. sees
解析： if引導的與過去相反的虛擬。
5. Most insurance agents would rather you______ anything about collecting claims until they investigate the situation.
A. do B. don’t C. didn’t D. didn’t do
解析：(D)would rather後接從句要求用虛擬語氣，形式為過去式，表示對現在或將來的假設，或為過去完成式表示對過去的情況的假設。6. Although most adopted persons want the right to know who their natural parents are, some who have found them wish that they ______ the experience of meeting.
A. hadn’t B. didn’t have had C. hadn’t had D. hadn’t have
解析：(C)who引導的定語從句中的現在完成時表示動作業已發生，所以主句中表示的虛擬是針對已經發生了的行為，所以應該用過去完成式表示對過去的虛擬。
7. Without electronic computers, much of today’s advanced technology ______ .
A. will not have been achieved B. have not been achieved
C. would not have been achieved D. had not been achieved
解析：(C)這是一人含蓄虛擬條件句，通過介詞短語without,表示潛在的一種假設，而主句中的情況也早已經發生，所以是對過去情況的一種假設，因此用would not have been achieved這一形式。
8. He told her to return the book in time so that others ______ a chance to read it .
A. may have B. will have C. would have D. might have
解析：(D)連so that引導的從句中要求用虛擬語氣，表示一種假設，形式為might+動詞原形。
9. It is time that the government ______ measures to protect the rare birds and animals.
A. takes B. took C. has taken D. taking
解析：(B)It is time that是一種要求從句用虛擬語氣的常見句型。虛擬語氣形式為動詞的過去式。
10. He was very busy yesterday, otherwise he ______ to the meeting.
A. would come B. came C. would have come D. had come
解析：(C)otherwise用來表示一種含蓄的'虛擬假設，因為是對過去(yesterday)的情況的假設，所以應該用would have come形式。
拓展閱讀：英語六級常見虛擬語氣型別
一、If 型
If條件狀語從句表示的虛擬語氣，其句型結構如下：
從句 | 主句 | |
與過去事實相反 | had done | would/could/might have done |
與現在事實相反 | did/were | would/could/might do |
與將來事實相反 | were to do/should do/did | would/could/might do |
特別值得注意的是，這種虛擬語氣的形式存在交叉虛擬，即如果從句發生的動作和主句發生的動作不一致(例如：從句動作發生在過去，主句動作發生在現在)，謂語動詞要根據表示的時間進行調整。例如：
If Peter had applied for the post, he would probably get it now.
要是彼得申請了那職位，他很可能現在就得到了。
If he had left for Shanghai yesterday, he would get there now.
如果他昨天動身去上海的話，他現在已經到那裡了。
二、Wish型
1. wish後的賓語從句用虛擬語氣，其句型結構如下：
與過去事實相反 wish that 從句的謂語動詞用had done
與現在事實相反 wish that 從句的謂語動詞用did
與將來事實相反 wish that 從句的謂語動詞用would/could do
例如：
I wish they would change the menu.
他們要是改變一下選單就好了。
I wish I hadn’t spent so much money.
我要是沒花那麼多的錢就好了。
同樣地，在as if/as though引導的賓語從句中和以if only引導的帶有感嘆色彩的虛擬語氣句子中，謂語動詞與wish引導的賓語從句中的虛擬形式相同。
2. 由if only 引導的虛擬語氣
與過去事實相反 if only 謂語動詞用had done
與現在事實相反 if only 謂語動詞用did
例如：
If only she had asked someone’s advice!
她要是徵求了別人的意見就好了!
3. 由as if/as though 引導的虛擬語氣
與過去事實相反 as if/as though謂語動詞用had done
與現在事實相反 as if/as though謂語動詞用did
例如：
He talks about Rome as if he had been there himself.
談論起羅馬來就像他去過似的。
He orders me as though I were his wife.
他向我發號施令就好像我是他的妻子似的。
三、強制性虛擬語氣
1. 表示建議、命令、勸告、決心等主觀色彩的動詞 + that + (should)+ 動詞原形，其中should經常被省略。這類動詞包括：advise，ask，command，decide，demand，desire，determine， direct，insist，maintain，move(動議，規定)，order，prefer，propose，recommend，require，stipulate，suggest等等。例如：
It is politely requested by the hotel management that radios (should) not be played after 11 o'clock at night.
酒店管理人員懇請房客在晚上11點之後不要開啟收音機。
2. 以上動詞轉化為名詞，如suggestion，proposal，demand，order，command，advice，desire，requirement，request，agreement，determination，preference，resolution，indication，後接同位語從句或表語從句時，從句要求用虛擬語氣，其謂語部分用should + 動詞原形，should可以省略。例如：
We are all for your proposal that discussion should be put off.
我們都支援你推遲討論的建議。
3. 值得注意的是，只有suggest意為“建議”、insist意為“堅持認為”時，從句用虛擬語氣，當suggest意為“暗示”、insist意為“堅持說”時，從句不用虛擬語氣。例如：
When the son suggested that they should go to park onSunday, the expression on his father suggested that he agreed with him.
當兒子提議星期天去公園時，父親用表情表示了默許。
The boy insisted that he didn’t cheat in the exam.
這個孩子堅持說他沒有在考試中作弊。(考試已經結束)
The boy insisted that he shouldn’t cheat in the exam.
這個孩子堅持認為不應該在考試中作弊。(考試還未進行)
is/was + 形容詞/過去分詞 + that + (should) + 動詞原形，這些形容詞主要表示必要性、重要性、強制性、合適性、義務性，即某人對某事的反應。這類詞包括：important，natural，desirable，possible，astonishing，advisable，anxious，appropriate，compulsory，crucial，eager，essential，fitting，imperative，improper，necessary，obligatory，preferable，proper，urgent，vital，shocked，requested，amazing，strange，odd，ridiculous，surprising，unthinkable，incredible等等。例如：
It is important that students graduating from universities should have not only theory but also practice.
大學畢業生不僅要有理論知識，更要有實踐經驗，這一點很重要。
It is surprising that they should kill the time like that.
他們竟然這樣打發時間，真是太奇怪了。
