问题补充：

., I have never seen anyone who’s as capable as John.

A. As long as I have traveled

B. Now that I have traveled too much

C. Much as I have traveled

D. As I have traveled too much

答案：

A. As long as I have traveled

B. Now that I have traveled too much

(答案→)C. Much as I have traveled

D. As I have traveled too much

解析：这是一个让步状语从句。As在引导让步状语从句时，要把所强调的形容词放在句首。句意是：虽然我走过了那么多的地方，但我从来没见过像John这样能干的人。
