1、一般条件句中的虚拟语气

2、条件句中虚拟语气的倒装； 假设条件虚拟倒装。 条件从句中含有 shuld，were， had 三个助动词并且放在句首时，可以把if省略。If I were yu, I wuld give it up.Were I yu, I wuld give it up. If I had had time, I wuld have run rund that lake again.Had I had time, I wuld have run rund that lake again.If there shuld be a fld, what shuld we d? a fld, what shuld we d?
Shul there be
3. 名词性从句的虚拟语气。主要是表示命令、要求、建议的虚拟语气。
宾语从句。常见动词：一个坚持：insist两个命令：rder, cmmand 三个建议：advise, suggest, prpse五个要求：demand , require, request, desire ask
这些动词后面的宾语从句要使用虚拟语气用法。即从句中的动词 使用shuld + 动词原形，或者将shuld省略。
我们建议Tm去休息一下。他坚决要求我到场。国王命令囚犯明天要实施死刑。他们要求我们派他们去那儿工作。
We suggested that Tm (shuld) have a rest.
He insisted that I (shuld) be present.
The king rdered that the prisners (shuld) be killed the next day.
They requested that we (shuld) send them t wrk there.
2、以上动词相应的名词构成的名词性从句（包括主语从句，表语从句和同位语从句）也要使用虚拟语气。从句中的动词形式一样。 rder, advice, suggestin, prpsal, demand, request, desire
It’s suggested that the plan be carried ut.My demand is that she shuld cme t see me nce a week.All f us are fr the advice that the chemical factry shuld be clsed dwn.
4、几种特殊结构中虚拟语气的用法；

过去时 (did/were)
过去完成时 (had dne)
wuld/culd/might+V. shuld
I wish I were a bird. (现在)I wish I hadn’t made such a mistake. (过去)We wish ur parents wuldn’t punish us. (未来)
