固定搭配：charge (a price，数额) for sth.

three times sth.三倍的某物

oliviachens

three times the price that the drug’s maker charges for another product with the same active ingredient

that引导定语从句，先行词为the price，定语从句中，that做charge的宾语

刚查了下语法书
基数词 + times + as + 形容词/副词原级 + as 。。。
基数词 + times + 形容词/副词比较级 + than 。。。
基数词 + times + the + 表示大小或数量的名词（如size，length等） + of 。

。。

那这题是不是考的是第三种用法？应该选D阿
