Daniel plays chess -------- ,if not better than,David. A、as well B、as well as C、well D、better为什么该选B呢?

问题描述:

Daniel plays chess -------- ,if not better than,David. A、as well B、as well as C、well D、better
为什么该选B呢?

if not better than是插入语,可以没有.去掉这个插入语,就变成:
Daniel plays chess --------David.
因此用as well as
