–-Did you mind if we set out earlier tomorrow morning?

---Well, I’d rather you ．

A. don’t

B. won’t

C. didn’t

D. wouldn’t

答案：

A. don’t

B. won’t

(答案→)C. didn’t

D. wouldn’t

解析：考查虚拟语气。Would rather+(that)从句结构中，从句谓语动词要用虚拟语气，根据句子可知指的是明天的事，指将来的虚拟，要用过去式，补充完整句子应是I’d rather you didn’t set out earlier tomorrow morning。所以选C。
