退时态:真实语气中的现在时变成过去时,过去时变成过去完成时,将来时变成过去将来时

1.条件句中:

 If it were not for…;If it hadn't been for…这两种句型表示“要是没有”,相当于but for

If it had not been for the PLA man, he would not be studying English now.

 if…only…(或If only…)表示“要是…就好了”

1.名词性从句:

 demand/suugest/order/insist/propose/request/ask/advise/prefer/command/desire that…

They demanded that the aggressor troops (should) be withdrawn immediately.

由insist引导的宾语从句可以虚拟也可以不虚拟:

He insisted that he was right.坚持认为

He insisted that we should agree with him.坚持某事

由suggest引导的宾语从句可以虚拟也可以不虚拟:

His white face suggests that his not healthy.表明

He suggested that we have a rest.建议

If I could only see him once!

If only I had listened to your advice. 很明显,这种句型省略了主句

2.其他状语从句中:

 as if/as though/even if…

Tom looked sad as if he had heard bad news.

I won't lend you any money even I had money.

3.名词性从句:

 wish that…(hope后的宾语从句不虚拟)

I wish I were as strong as you.

How I wish it wasn't raining!

 would rather/would sooner/had rather that…表示“宁愿”

I would rather they came tomorrow.

I could go myself but I would sooner you went.

I had rather you told him than I did.

 It is time/high time that…

It is time we went to bed.

虚拟语气的句式

1与现在事实相反的虚拟语气形式If+主语+动词的过去式(be要用were)……, 主句主语+would(或should, could, might)+动词原形。例如:If I were you, I would buy a car. 如果我是你, 我就买辆车。(注: 在第一人称中, 主句中的would也可用should)2. 与过去事实相反的虚拟语气形式If+主语+had+过去分词……, 主句主语+would(或should, could, might)+have+过去分词。例如:①If my lawyer __________ here last Saturday, he __________ me from going. (MET'89)A. had been; would have prevented B. had been; would preventC. were; would prevent D. were; would have prevented此题的正确答案为A。②I didn't see your sister at the meeting. If she __________, she would have met my brother. (NMET'94)A. has come B. did come C. came D. had come此题的正确答案为D。附加:3. 与将来事实相反的虚拟语气形式If+主语+动词的过去式(或were to +动词原形, 或should +动词原形)……, 主句主语+would(或should, could, might)+动词原形。

例如:If it should rain tomorrow, what would we do? 如果明天下雨, 我们怎么办? (注: 从句中的should rain可以换成were to rain或rained)...

英语中虚拟语气的句式结构

虚拟语气

一、if引导的虚拟条件句(表示与事实相反的假设):现在:If+主语+过去式/were,主语+should/would/could/might+动词原形过去:If+主语+had+过去分词,主语+should/would/could/might+have+过去分词过去式/were将来:If+主语+should+动词原形,主语+should/would/could/might+动词原形wereto+动词原形另外:有些词,如:or/otherwise(否则);without(没有);butfor(要不是……)等,表示一个隐含的条件,所用的虚拟语气与if引导的虚拟条件句结构相同注意:if引导的虚拟条件句中,谓语部分含有were/had/should,可将引导词if省略,并将were/had/should提到句首。

二、wish之后接的宾语从句(表示不可能实现的愿望):过去式/were(现在)Wish+(that)had+过去分词(过去)would/could/might+动词原形(将来)

三、asif/asthough常与seem/look/appear等动词连用,表示“看起来似乎……好象……”;以及ifonly表示“要是……该多好啊”所用的虚拟语气结构与wish结构相同;

四、虚拟语气在名词从句中的运用:

1、表示“命令”、“建议”、“要求”、“坚持”等词后所带的名词从句用虚拟语气,结构都是:Array,其中should可以省略。记忆口诀:insist

2、动词 order+(that)+主语+Arrayadvise/suggest/recommend(宾语从句)require

3、名词:advice/suggestion/order/request之后
