I would rather you -- talking.

答案是B
我给你讲讲would rather的用法
1.would rather + 动词原形 "宁愿做..."
I would rather die.我宁愿死
2.would rather do than do “宁愿做某事而不愿做...”
I would rather die than give in.我宁愿死也不愿屈服
3.would rather + 从句
因为和事实相反,所以用虚拟语气.与现在或将来事实相反,用一般过去时；与过去事实相反,用过去完成时
I would rather you had come yesterday.
I would rather we go tomorrow.
补充：would rather只有接从句的时候虚拟.
从句只有两种时态:过去时和过去完成时
