Question

John plays the piano _____, if not better than, David. But he never shows off in public.

A. as well        B. as well as         C. so well    D. so well as

Answer 1

B

解析:

这是一个比较状语从句，引导比较状语从句的连词和词组有：as…as,

than, not so…as, the more…, the more…等。这是个肯定句，所以不能用D，因为有比较的对象也就是有宾语，所以不能省略第二个as.
