Question

I'd rather 是虚拟语气句型吗/

Answer 1

...
4. would rather后也可跟从句，表示主语宁愿让某人干某事。这时，从句谓语动词要用虚拟语气，即用一般过去时表示现在或将来要做的事；用过去完成时表示已经做过的事或过去要做的事。例如：
I'd rather she set out to do the work now. 我宁愿她现在就着手做这项工作。
I'd rather you met her at the airport tomorrow morning. 我但愿你明天早上能在机场见到她。
I'd rather you hadn't told him the news that day. 我真希望你那天没有把那个消息告诉他。
5. would rather后还可接动词的完成式，表示主语要做某事，而结果却事与愿违。例如：
I'd rather have left a note on her desk. 我本想留张字条在她书桌上的。（事实上没有留）
试比较
I'd rather I left a note on her desk. 我宁可留张字条在她的书桌上。
尤其要注意对would rather have done something的理解，它和其他情态动词的完成体用法类似, 表示“宁愿（过去）做了某事”，实际上没做。

Answer 2

I'd rather do
i would do rather than do
