虚拟语气 虚拟语气例句

在表示一种纯然假想的情况或主观愿望时，动词需用一种特殊形式，称为虚拟语气。虚拟语气在形式上大致分为三类：
1）现在虚拟语气——主要用动词原形：
Good bless you. 愿上帝保佑你。
It is essential that the ban be lifted. 解除禁令至关重要。
She petitioned the king that her father be pardoned.她恳求国王赦免她的父亲。
2）过去虚拟语气——和陈述语气的过去式相同，但动词be要用were形式：
Imagine your child played truant. 设想你的孩子逃学。
She treated me as though I were (was) a stranger. 她待我如陌生人。
If only I were not so nervous. 我要是不那么紧张就好了。
3）过去完成形式——和陈述语句中的过去完成时相同：
I wish I hadn’t done so. 但愿我没这样做。
If I had seen her, I would have told her. 如果我见到她，我就会告诉她了。
If only I had listened to your advice. 我要是听了你的劝告就好了。
有些情态动词，特别是should，would，might，could常用在虚拟语气中。

虚拟条件句
包含条件从句的句子都是条件句，有些条件句是可能实现的，如：
If I have time I’ll come over to see you. 如果我有时间我就来看你。
If we leave now, we can still catch the train.如果我们现在动身，还可能赶上火车。
I won’t go to the party unless they invite me.除非他们邀请我，否则我不会参加这个晚会。
If you are waiting for a bus you’d better join the queue.如果你是在等车，你最好排队。
If he has written the letter, I’ll post it. 如果他已把信写好，我就去发。
这种条件句称为真实条件句（Sentences of RealCondition）。另有一些条件句表示纯然假想的情况，称为虚拟条件句（Sentences of UnrealCondition），在这类条件句中谓语动词就需要用虚拟语气：
If I had enough money, I would buy a computer.如果我有足够的钱，我将买一台电脑。（但我没有）
If you had arrived a little earlier, you would haveseen her. 你要是早来一会儿就见到她了。
表示现在和将来情况的虚拟条件句
1）表示现在或将来情况的虚拟条件句，动词形式可以下表表示：
条件从句中的谓语主语谓语
相当于过去式形式would +动词原形
这类句子或表示与事实相反的情况或实现可能性不大的情况：
If I had a map I would lend it to you.如果我有地图我就借给你。（但我没有）
If you left your bicycle outside, someone wouldsteal it. 如果你把自行车放在外边，有人会偷的。（当然你不会这样做）

在后面这类句子中，主语的谓语有时可用祈使语气（见上例），或用陈述语气：
If I should be free tomorrow, I will come to see you.如果明天我有空我会来看你的。
4）在某些条件从句（如包括were和should的从句）中，if有时可省略，这时语序要改为倒装：
Were I Tom I would refuse. 如果我是汤姆我会拒绝。
Were I in your shoes I would let him know what I thoughtof him. 如果我处于你的地位，我会让他知道我对他的看法。

Were it not for their loan, our life would be verydifficult. 要不是有他们的贷款，我们的生活会很困难。

If that be the official view, it cannot be accepted.如果这是官方的看法，这是不能接受的。

这是比较大气的说法，口语中很少使用。
表示过去情况的虚拟条件句。
1）表示过去情况的虚拟条件句动词形式可以下表表示：
条件从句的谓语主语谓语had

If he had apologized, you should have done sotoo. 如果他道歉了，你也应当这样做。
2）从句中也可用had not been for来构成谓语，表示“要不是”：

一些特殊的虚拟条件句
1）错综时间条件句：
有些条件句主句谓语和从句谓语表示的动作在时间上并不一致，这类句子称为错综时间条件句（Conditional Sentences ofMixed Time），如：
If the weather had been more favorable, the cropswould be growing still better.如果前些时候天气好一点，庄稼现在会长的更好。
If he had received six more votes, he would beour chairman now. 他要是多得六票，现在就是我们的主席了。

If he were leaving, you would have heard aboutit. 如果他真的要走，你早就听到消息了。
If he had been trying hard, her parents wouldn’tbe so worried. 如果她一直很努力，她的父母也不会这样着急了。
2）含蓄条件句：
有些句子虽不含条件从句，但意思和条件句差不多，这种句子称为含蓄条件句（Sentences of ImpliedCondition），在这种句子中也可能需用虚拟语气：
I might see her personally, it would be better.我可能亲自去见她，这样会好一些。
I would have written before but I have been ill.要不是病了，我早给你写信了。

She would have done anything to make amends.她愿做任何事来赔罪。
3）某些情态动词的使用：
某些情态动词，特别是should，would，could，might，在口语中用得很多，使语气变得客气委婉：
Would you mind shutting the window? 劳驾把窗子关上好吗？
Would you tell me how to get to the tube?可否请告诉我怎么去地铁站？

Might I ask for a photograph of Mr. Strakov?我可否要一张斯特拉可夫先生的照片？
If necessary, you might shorten it. 必要的话你可以把它缩短。
I might have come to a wrong conclusion.我也许得出了错误的结论。
这类句子的谓语虽不一定是虚拟语气，却很接近虚拟语气。一是它们在形式上和虚拟条件句中的谓语形式很相近；二是它们不受时态的限制，现在情况可以过去形式表示；三是和一般陈述语气有些差异，更带主观色彩。因此，说它们是虚拟语气或接近虚拟语气也未尝不可。

虚拟语气在宾语从句中的运用
在某些动词后的宾语从句中需用虚拟语气：
1）wish后的宾语从句：
在wish后的宾语从句中谓语主要有两种形式（表示与事实相反的情况）：
a.用过去式表示现在情况，动词be用were时较多（也有人用was）：
I wish I knew what was going to happen.但愿我知道将要发生什么事。
I wish I could help you. 但愿我能帮助你。（但我不能）
I wish I had more time. 但愿我有更多的时间。
I wish I were (was) young again. 真希望我能再年轻一次。
b. 用相当于过去完成时的形式，表示过去的情况（常有遗憾的味道）：

My father wishes (that) he had gone touniversity. 我父亲很希望自己上过大学。
I wish you hadn’t told me all this.但愿你没告诉我这一切。

间或用would构成谓语：
I wish he wouldn’t go out every night. 但愿他不要每晚都出去。

I wish you wouldn’t be so noisy. 但愿你别这么吵。
2）would rather (sooner)后的宾语从句：
谓语多用相当于过去式的形式，表示现在或将来的情况：

“Do you mind if I smoke here?” “I’d rather you didn’t.”“我在此抽烟你介意吗？”“我倒是希望你别抽。”
I would rather you told me the truth. 我宁愿你给我讲真话。
I’d sooner you didn’t ask me that question.我宁愿你别问我那个问题。
在had rather和prefer后的宾语从句中有时也可用虚拟语气：

在suppose后的宾语从句中也可能包含虚拟语气：

Suppose they did not believe him what would they do tohim? 假如他们不相信他的话，他们会把他怎么样？
3）suggest，demand，insist，ask这类动词后的宾语从句：
从这类从句中美国人多用动词原形（也就是现在虚拟语气）：

They intended that the news (should) be suppressed.他们打算封锁这条消息。
She petitioned the king that her son (should) be pardoned.她恳求国王宽恕她的儿子。
英国人过去多用“should+动词原形”作这类从句中的谓语，但现在用原形的人也越来越多了，另外这类句子也可变为被动语态，宾语丛句则成了主语从句：
It is suggested that we make a special study of theproblem. 有人建议我们对这问题作专门研究。
It was intended that you be the candidate. 打算让你作候选人。
It was proposed that this matter be discussed at the nextmeeting. 有人提议这问题下次会上再议。

虚拟语气在主语、表语等从句中的运用

另外，在有些这类结构的句子中，主语从句的谓语由“should+动词原形”构成，这时多带有一些情感色彩，可译为“竟然”等（表示一种不可思议的状况）：

虚拟语气在状语从句中的运用
在某些状语从句中，谓语有时用虚拟语气，特别是在下面几类状语中：
1）as if，as though引导的状语从句：
这类状语从句中的谓语形式和一般虚拟语气差不多，表示现在情况时用过去虚拟语气（a），表示过去情况时用完成形式（b）：

Whether she be right or wrong we will support her.不管她是对还是错。

这些句子（特别是第一类）的从句谓语也可用陈述语气：

上面的b类句子可以看作是一种句型。

I lent him £50 so that he might go for a holiday.我借给他五十英镑以便他能去度假。

He was amazed that some countries should expressindignation at it. 他很惊讶有些国家竟对此感到愤怒。
