英语虚拟语气动词用法:
(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, command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.
某些从句中的虚拟语气用法:
1. would rather后的句子用虚拟语气
通常用一般过去时表示现在或将来的愿望,用过去完成时表过去的愿望。如:
I’d rather you came next Saturday. 我宁愿你下星期六来。
I’d rather you hadn’t done that. 我宁愿你没这样做。
2. 某些用虚拟语气的主语从句
形容词important, impossible, necessary等后的主语从句通常用虚拟语气。如:
It is impossible that he should go home. 他不可能会回家去。
It is necessary that I should return it right now. 我有必要马上还回去。
注:在It is amazing (strange, surprising, astonishing, a pity, a shame)以及 I am surprised (sorry) 和I regret等结构后的that 从句中有时也用should,表示说话人的惊异、懊悔、失望等情感,常含有“竟然”之意。如:
It’s strange that he should be so rude. 他竟如此无礼,真是奇怪。
I’m surprised that he should have failed. 他竟然失败了,这使我很吃惊。
若不用虚拟语气也可以,则不带感色彩,比较:
It’s a pity that he failed the exam. 他考试没及格,真是遗憾。
It’s a pity that he should have failed the exam. 他考试竟没及格,真是遗憾。
