I would rather you came tomorrow.有什么语法？

would rather后跟从句用虚拟语气，表示与事实相反的希望。与过去事实相反的用一般过去时

I would rather you came tomorrow.我宁愿你明天来。这里涉及的语法是 would rather do sth.宁愿做。。。事情

我宁愿你明天再来。would rather sb do sth

I would rather you come tomorrow.....我宁愿你明天来。。。

would rather+从句，是一个常用的虚拟语气句型 Would rather+从句,谓语一般用过去时来表示现在或将来。其意为“宁愿……,还是…… 好些”“一个人宁愿另一个人做某事”。引导从句的that常省略。在谈到过去的动作时，谓语则用过去完成时。
例 John wants to see me today. I would rather he came to tomorrow than today. 约翰今天想去看我。我宁愿他明天来看我而不是今天。(句中came不是表示过去而是表示将来)
We’d rather he paid us the money tomorrow. 我们宁愿他明天付给我们那笔钱。
Don’t come tomorrow. I’d rather you came next weekend. 明天别来。我希望你下周末来。
