Question

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

A. As long as I traveled
B. Now that I have traveled so much
C. Although I have traveled so much
D. As I have traveled so much

Answer 1

答案C
此处考查引导状语从句的连词的用法。as long as“只要”，引导条件状语从句；now that“既然、由于”，引导原因状语从句；although“虽然、尽管”，引导让步主语从句；as也可以引导让步状语从句，但必须用倒装语序much as I have traveled。根据句意和语法，应该选C。
