问题补充：

—I’m going to Larry’s party. But I don’t know what to wear.

—If I you, I wear a dress.

A. am; will

B. were; will

C. were; would

D. am; would

答案：

A. am; will

B. were; will

(答案→)C. were; would

D. am; would

解析：根据题干，本句的意思应是“如果我是你，我将穿一件裙子。”“我”是不可能成为“你”，所以本句是一个虚拟语气。对于虚拟语气，从句应该用过去式（be动词，不论是第几人称，都用were），主句用would do。所以本题选C。
