问题描述:

Don't laugh at her.She is_____any of the others in your class.A as clever a student as
B as a clever student as 为什么选A,B为什么不行

很明显as...as 中间需要是adj而不能有偏正的名词或语句

因为是固定搭配

as...as 间能填的词一般都是形容词,像这里的clever.而B选项是“一个聪明的学生”,这是一个偏正结构,也就是所谓的名词,所以,B明显不对.
说到as...as 结构,其实它的用法有点像such/so,such+a/an+形容词+名词;so+形容词+a/an+名词,这是英语中的固定搭配.
