would rather, would sooner, had rather, would prefer等用来表达主观愿望，它们之后的宾语从句中需用虚拟语气。谓语动词用过去式表示现在或将来，用过去完成式表示过去。如：I would rather he came tomorrow than today.若某人愿自己做某事，would rather后用动词原形。如：I would rather stay at home today．
那么、would rather之后有没有接should+动词原形的用法。
should是“应该”的意思，用于虚拟语气中基本也保持本意不变。
比如说：
You should have locked the door.你应该锁上门的（应该做但没做，表假设虚拟）
I suggest you should stop this project,我建议你终止这项项目（suggest表“建议”之意时后用虚拟语气）
would rather等表主观愿望的词后既接虚拟语气，理论上来讲可以用should。但习惯上不用，因为这样翻译过来就是“某人宁愿……应该……”，“宁愿”和“应该”前者表说话者主观意愿，后者表客观条件的要求，搭配起来逻辑上有些矛盾。
表主观愿望的词跟虚拟语气需要用助动词时一般用would，could等。一般不用should，但具体问题也要具体分析。

由would rather/sooner，would sooner，had rather，would just as soon，would prefer等结构引导的虚拟语气，其句型结构如下：
与过去事实相反 would rather/sooner…谓语动词用had done
与现在、将来事实相反 would rather/sooner…谓语动词用did
Would rather+从句是一个常用的须用虚拟语气的句型：would rather+从句（谓语用一般过去时），其意为“宁愿……, 还是……好些“（more willingly）。
如：John wants to see you today.—I would rather he came tomorrow than today.(句中came 不是表示过去而是表示将来)
Look here,sir. Wouldn’t you rather I was out of this? (句中was表示现在)
又如：Would you rather I did it?
I’d rather you posted the letter right away.
如果表示过去的情况，则应该用过去完成时：I would rather +从句（谓语用过去完成时）。
如：I would rather you had been present.
I would rather the teacher had given some advices for my son.
与would rather类似用法的句型还有：I would sooner…, I would just as soo…, 等。
如：I’d sooner she left the heavy end of the work to someone else.
I’d just as soon you had return the book yesterday.
