英语早间课堂:It is important that S (should) do.
We've learned how subjunctive is used in a complex sentence including an objective clause recently. And first of all let's have a summary and review this morning.
I 虚拟语气在wish后面的宾语从句的使用，the sentence patterns are as follows:
① S wish ( that ) S was ( were ) . ② S wish ( that ) S did.
③ S wish ( that ) S had done. ④ S wish ( that ) S would do.
⑤ S wish ( that ) S could do.
II 虚拟语气在would rather, would sooner 后面的宾语从句中的使用，the sentence patterns are below:
① S would rather ( that ) S did. ② S would rather ( that ) S had done. ③ S would sooner ( that ) S did.
④S would sooner ( that ) S had done.
III 虚拟语气在某些动词后的宾语从句中的使用，其中一些动词可以看这样记忆：一个“坚持”(insist), 两个“命令”(order, command，),三个“建议”(suggest, advise, propose), 五个“要求”(demand, require, request, ask，urge)。
除此之外，还有表“心愿”的desire, 表“决定”的decide,vote, 表“规定”的 decree, 表“打算”的intend, 表“恳求”的petition,表“推荐”的recommend。对于以上动词，我们就要死记硬背了。
As for the above verbs, the sentence patterns when using subjunctive are all the same : S + 动词+ (that)S (should)do.
IIII 虚拟语气在suppose 后面的宾语从句中的使用，the sentence pattern are:
① S suppose ( that ) S did. ② S suppose ( that ) S had done.
备注：(that)这个表示这个词可以在句子中省略，还有(should)。S 是subject这个单词的缩写形式，意思是：主语。
