【考点一、虚拟语气在条件句中的使用】

1）条件句的从句和主句的谓语动词形式表及几点说明

①条件句的从句和主句的谓语动词形式表。

虚拟条件句

主句

主语+should, would, 与现在事实If+主语+动词的过去式

（becould, might+动词原相反的假设

动词用were）

形

与过去事实相反的假设

If + 主语+ had +过去分词

主语+should, would, could, might+ have+过去分词

例句

If I had enough money, I would buy the house. If you had listened to me yesterday, you would have finished the work. ①If+主语+动词的过去式

If it were to rain ②If +主语+were to +动词原主语+should, would, 与将来事实tomorrow, the sports 形

could, might+动词原相反的假设

meeting would be put ③If + 主语+should+动词原形

off. 形

②特殊结构的条件句：“If it were not for…”或“If it had not been for…”, 前者与现在事实相反，后者与过去事实相反。相当于but for或without。

2）虚拟条件句的省略情况

①

省略if的虚拟条件句：

如果虚拟条件句的谓语部分有were，had和should时，可省略if，把were，had和should放到从句主语前面去。

3）含蓄的虚拟语气

①

用介词without（或with no），but for等表示“如果没有”。

But for air and water，nothing could live．要是没有空气和水，也就不能有生命。

②

用动词不定式、比较级、连词

but等来表示虚拟条件，还可以根据内容的需要来应用虚拟语气。

She would have come here，but she was too busy with her homework．

她本来早就要到这里来，但是她当时太忙于写作业了。

【考点二、虚拟语气在宾语从句中的应用】

1）宾语从句在表示提议、要求、命令、意志等动词后，可用“should do”或“do型”（be原形动词）虚拟语气。这类动词有：suggest，request，demand，urge，propose，prefer，advise，[来源:学科网][来源学科网Z|X|X|K][来源:Zxxk.Com][来源学科网]

insist，require，order，command，maintain，ask，object 等。例如：

2）宾语从句用在动词wish之后

①

过去式用来表示现在的愿望；“could（would，might）+动词原形”用来表示将来的愿望，

I wish it were true．我但愿这是真的。

I wish I could live on the moon one day.

我希望有一天我能住在月亮上。

②“had +过去分词”或“could（would，might）+have+过去分词”都是用来表示无能为力的过去愿望。

【考点四、虚拟语气在“It is time that …”句型中的应用】

在“

It +is +（high或about）time +（that）主语从句”句型中，可用“did型”或是“should + do型”虚拟语气，表示“做某事的时间早完了或早该做了”。

【考点五、虚拟语气在表语从句和同位语从句中的应用】

在proposal，suggestion，order，requirement，desire，decision，advice，plan，necessity等表示提议、要求、命令等名词的后面的表语从句和同位语从句中，可用“动词原形”或“should + 动词原形”虚拟语气。例如：
