GRAMMER 语法

虚拟语气 The Subjunctive Mood

语气(mood)是一种动词形式,用以表示 说话者的意图或态度。
在英语中随着说话人意图的不同,动词需用 不同的形式,称为语气。英语语气有三种: ①陈述语气(indicative mood) ②祈使语气(imperative mood)

③虚拟语气(subjunctive mood)

语气的分类
? 陈述语气:表示动作或状态是现实的、 确定的或符合事实的,用于陈述句、疑 问句和某些感叹句。 I went to the theatre yesterday. Jack hasn’t come back home yet. ? 祈使语气:表示说话人对对方的请求、 邀请、命令、警告或劝告等。

Let’s go. Don’t touch anything on the table.

? 虚拟语气: 表示动作或状态不是客观存在的事 要求、有时是一种非真实的假设、料想,或是

实,而是表示说话人的一种愿望、建议、命令、 不可能实现的与事实相反的愿望。虚拟语气主

要用于if条件状语从句, 也可用于名词性从句等。 ①If I were you, I would not leave her alone. ②Our teacher suggested that we (should) go to the library this afternoon.

虚拟语气在条件状语从句中的应用
条件句表示主句的条件, 分真实条件句和 虚拟条件句两种。 a. 真实条件句表示条件是真的或有可能实 现的, 采用陈述语气。 b. 虚拟条件句/非真实条件句表示条件是无 法实现或几乎无法实现的, 采用虚拟语 气。

真实条件句

发生。主句用一般将来时, if从句用一般

现在时。

If I were a boy, I would join the army.

b. 表示与过去事实相反的假设

注意一:

含有虚拟语气的条件状 语从句中如果有had, should, were三个词, 可以将if 省略,并将这 三个词提至句首,从而 构成部分倒装。

Should it be fine, we would go for an outing.

If they had had time, they would have come and helped us.
Had they had time, they would have come and helped us.

If it were to rain tomorrow, the football match would be put off.
Were it to rain tomorrow, the football match would be put off.

注意二:
当条件状语从句表示的行 为和主句表示的行为所发 生的时间不一致时,被称 为“错综时间条件句”, 动词的形式要根据它所表 示的时间作出相应的调整。

If the staff had been more careful,

the mall would not be on fire now.

如果他(过去)早点出发,他现在已到家了。

If he had set out earlier, he would be home now.

如果你昨天问问他,你现在就知道该
怎么做了。 If you had asked him yesterday, you would know what to do now. 如果我是你,我昨晚就不会错过那场电影。 If I were you, I wouldn’t have missed the movie last night.

注意三:
含蓄条件句:
有时可用介词短语代替条件状 语从句.常用的介词有with, without, but for (要不是,若非) 等。

What would you do with a million dollars? (=if you had a million dollars)? We could not have finished the work ahead of time without your help. (=if we hadn’t got your help). But for the rain we would have finished the work. (=If it hadn’t been for the rain),

注意四:
? 含蓄条件句 有时为了表达的需要,在虚 拟语气中并不是总是出现if 引导的条件句,而是通过其 他手段来代替条件句。

I was ill that day. Otherwise , I would have taken part in the sports meet.(副词) =If I had not been ill that day, I would have taken… He telephoned to inform me of your birthday, or I would have known nothing about it.(连词) =If he had not informed me of your birthday, I would have known nothing about it. I might have given you more help, but I was too busy.(连词) =I might have given you more help, if I had not been too busy.

注意四: 省略主句或从句
1. You could have passed the exam. could have done should have done/shouldn’t have done ought to have done/oughtn’t to have done 2. If my grandmother were with me! 3. If only she had not left.

注意五:
