【题目】My teacher speaks English well indeed, but of course not __ a native speaker.
A. as fluent as B. more fluent than
C. so fluently as D. much fluently than
在线课程【答案】C
【解析】
试题分析：考查同级比较。同级比较指由as/so+adj/adv+as结构构成，意为和…一样…。根据上文的speak可知，需要用副词进行修饰，故选择C，句意为：我的英语老师英语说的不错，但是当然还没有英语为母语的人说得流利。至于选项D，much并不构成比较关系。
