  3.在方式状语从句中

  由as if和as though等引导的方式状语从句中,如果从句所表达的情况是虚拟的,则①常用动词的过去式来表示与现在或当时的情况相反;如果是BE动词,则用were;②常用过去完成式来表示与过去的情况相反。例如:

  She loves the child as if he were her own.她爱这孩子就好像是她亲生的。

  (实际上不是她亲生的孩子)

  2.在目的状语从句中

  ①在由lest

  和in case等引导的目的状语从句中,用“should+动词原形” (should可省略)。例如:

  He ran away lest he(should)be seen.他跑走了,以免被人看到。

  She explained again and again in case he (should)misunderstand her.她解释了一遍又一遍,以免他误解她。

  in case等引导的目的状语从句中的谓语有时也可用陈述语气。此时,从句表示的就是真实情况,而不是虚拟情况。例如:

  Take warm clothes in case the weather iS cold.带上厚衣服,以防天气变冷。

  ②在由“so that…”和“in order that…”

  引导的目的从句中,要用“can/could/may/might/would+动词原形”,以表示目的并非事实。例如:

  She stayed at home for a few days sO that

  she might/could take care of her sick mother. 她在家呆了几天,以便照顾她生病的母亲。

  ③在由“for fear that…”引导的从句中,用“should+动词原形”(有时也可用may/might/would)。例如:

  Were l in your position,1 would go.如果我处在你的位子上,我就走了。

  Had you arrived five minutes earlier,you could have seen them off.如果你早到五分钟,

  你就可以给他们送行了。

  Should he come,tell him to ring me up.如果他来的话,叫他打电话给我。

  1.在假设条件句的if条件从句中

  假设条件句一般是由“if引导的条件从句+主句”构成。if从句中的谓语动词要用虚拟语气的形式。if从句的假设可以是与现在事实相反的条件、与过去事实相反的条件或者与将来不太可能成为事实的条件。下面分述表示这三种条件的if从句的结构:

  ①与现在的事实相反,其句子结构为“If+主语+were/谓语动词的过去式”。例如:

  If 1 were you,I shouldn’t do that.如果我是你,就不会做那件事了。

  We would gO with you if we had time.如果我们有时间的话,就和你一道去了。

  We could ask him if he were here.如果他在这儿,我们就可以问他了。

  ②与过去的事实相反,其句子结构为“If十主语+谓语动词的过去完成式”。例如:

  If he had seen you yesterday,he would have asked you about it如果昨天他见到你,他就会问你那件事了。

  If you had come earlier,you would have met him.如果你早点儿来,就会遇到他了。

  1 would have called you if I had known your telephone number.如果我知道你的电话号码,就打电话给你了。

  在名词“suggestion,proposal,idea,plan,order,advice’’等后面的同位语从句或表语从句中,用“should+动词原形”(should可省略)。例如:

  I made a proposal that we(should)hold a meeting next week.我提出了我们下个星期开会的建议。(同位语从句)

  His suggestion that the meeting(shoald)be held in this room has been accepted.他的关于在这个房间召开会议的建议被采纳了。(同位语从句)

  My idea is that we(should)get more people to attend the conference.我的想法是我们多找些人来参加会议。(表语从句)

  在句型“h is(high)time+(that)从句”中,谓语须用虚拟语气。用过去式表示现在或将来的意念,意为“现在是该做某事的时候了”。

  例如:

  h iS(hieh)time(that)we went home.我们该回家了。
