Question

【题目】In my view, biology is ________ chemistry, but a little easier than mathematics.

A. a subject so difficult as B. as a difficult subject as

C. difficult as a subject as D. as difficult a subject as

Answer 1

【答案】D

【解析】

试题分析：考查固定句型。句意：在我看来生物和化学是一样难的科目，但是比数学稍微容易些。固定结构as +形容词+a/an +单数名词 +as，表示...和...一样。故选D。
