I'd rather the two countries__an end to the war.then their people could live in peace.
a.put b.would put c.puts d.should put
这道题的考察点是什么?虚拟语气看与什么事实相反要看主句?这句是与过去事实相反?
这里是考WOULD RATHER DO?
应该是the two countries后面怎么判断?
怎么是对将来的虚拟?虚拟语气看与什么事实相反要看主句?

问题中的答案只可能是A.理由如下：
先谈一下would rather的用法：
would rather后接动词时,要用动词原形,即would rather do形式.例如：
I'd rather have a quiet night in front of the TV.我宁愿在电视机前度过一个安宁的夜晚.
We could eat later if you would rather do that.如果你愿意晚些吃的话也可以.
would rather后面可以接从句,但从句中要用虚拟语气.其虚拟语气的形式为：
表示过去时态或完成时态时用had done形式；
表示现在或将来时态时用did形式（即用过去式）.
请看例句：
I'd rather you hadn't done that.我真希望你没做过那件事.(表示过去）
I would rather none of that had ever happened in the past.但愿一切都没有发生过.(表示完成)
I'd rather I didn't see you again.我宁愿不再见着你.(表示将来)
I'd rather she didn't love.我宁可她不爱我.
提问中的I'd rather后面接的是从句,故从句中的谓语动词要用虚拟语气形式,而此处表示的是将来情况,故用谓语动词put的过去式,亦即put.
提问句句意：
但愿两个国家结束战争,这样它们的人民就能和平生活了.
