英语中表建议命令的动词且原型+should do虚拟的有哪些如题

网友回答

(1) 在主语从句中用来表示惊奇、惋惜、理应如此等,其谓语形式是should(可省) +动词原形,常用于以下三种句型中.
句型一:It is necessary (important,natural,strange,etc) that…
句型二:It is a pity (a shame,no wonder,etc) that…
句型三:It is suggested (requested,proposed,desired,etc) that…
如:It is strange that he (should) have done that.
It is a pity that he (should) be so careless.
It is requested that we (should) be so careless.
(2) 在宾语从句中用于 suggest,propose,move,insist,desire,demand,request,order,mand 等动词后的宾语从句中,表间接的命令和建议.其谓语形式是(should) + 动词原形.如:
I suggest that we (should) go swimming.
(3) 在表语从句中,表示间接的命令,要求、请求、建议、决定等,主句中的主语通常是 suggestion,proposal,request,orders,idea 等.从句谓语形式是(should)+动词原形.如:
His suggestion is that we (should) leave at once.
(4) 在同位语从句中,谓语形式是(should)+动词原形.如:
We received order that the work be done at once.
(5) 在 It is time that …句型中,其谓语动词形式是动词的过去式或
should +动词原形,should 不可省.如:It's time (that) we went ( should go) to school
