　　二、虚拟语气 英语中的虚拟语气有4种，一种是条件句中的虚拟语气，一种是含蓄条件句中的虚拟语气，一种是名词性从句中的虚拟语气，还有一种是状语从句中的虚拟语气。其中虚拟时态的运用很大程度上和其所处的句型有关。虚拟语气在三级考试中是一个比较重要的语法。下面我们也分四部分来看一下三级考试中虚拟语气的运用。

　　「评析」

　　1.对于虚拟条件句中时态的运用，首先应该熟记主从句动词与不同事实相反时的时态运用规则。解题时根据句子所表达的时间概念确定与什么事实相反，然后采用相应的时态。

　　① 如果与过去事实相反，从句中用过去完成时，主句中用would/should/could/might + have done的形式，如1）、3）、6）和7）。

　　1）If a better material______,the strength of the part would have been increased.（1992.6）

　　A.had been used

　　B.had been using

　　C.being used

　　D.using

　　**：A

　　3）______ you were busy, I wouldn't have bothered you with my question.（1996.6）

　　A.If I realized

　　B.Had I realized

　　C.Did I realize that

　　D.As I realized

　　**：B

　　注意：虚拟条件句的从句部分如果含有were, should, 或had, 可将if省略，再把were, should或had 移到从句句首，实行倒装。

　　6）Had the weather been good,the children ______ out for a work.（2001.6）

　　A.had gone

　　B.could have gone

　　C.would go

　　D.went

　　**：B

　　7）______ the advice of his friends, he would not have suffered such a heavy loss in his business.（2004.4）

　　A.If he took

　　B.If he should take

　　C.Were he to take

　　D.Had he taken

　　**：D

　　② 如果与现在事实相反，从句中用一般过去时，主句中用would/could/might/should + 原形动词，如5），表示与正在进行的事实相反用would/might/could/should + be doing的结构。

　　5）Do you think there would be less conflict in the world if all people ______the same language?

　　A.spoke

　　B.speak

　　C.had spoken

　　D.will speak

　　**：A

　　③ 如果表示将来不可能实现的事情，从句中用过去时，或were to / should + 原形动词，以上题4）表示的就属于这种情况。

　　4）______,I should ask them some questions.（1997.6）

　　A.Should they come to us

　　B.If they come to us

　　C.Were they come to us

　　D.Had they come to us

　　**：A

　　2.虚拟条件句有单一条件句，也有混合虚拟条件句，所以不能只根据从句与某一事实相反来判断主句就与该事实相反，同样，也不能想当然地认为主句与某一事实相反，从句也就与该事实相反。如2）：

　　2）If you ______that movie last night, you wouldn't be so sleepy.（1993.6）

　　A.hadn't watched

　　B.haven't watched

　　C.wouldn't have watched

　　D.didn't watch

　　**：A

　　从句与过去事实相反，而主句与现在事实相反。

　　再如：

　　If he weren't such a kind man, he wouldn't have lent a hand to such people as you the other day.（从句与现在事实相反，主句与过去事实相反。）

　　Were my friends not to come tomorrow, I wouldn't have bought so many foods.（从句与将来事实相反，主句与过去事实相反。）

　　3.if引导条件状语从句时，可以将were/had/should提至句首，省略if.考试时经常是将省略if的与含有if的选项并列，在这种情况下，应注意分清从句的时态，尽管多数情况下都是倒装的结构为正确选项。如3）、4）、6）和7）。

　　再如：

　　Were they here now, they could help us.

　　=If they were here now, they could help us.

　　Had you come earlier, you would have met him

　　=If you had come earlier, you would have met him.
