3. of the two toys, the child chose _____
A. the expensive one
B. one most expensive
C. a least expensive
D. the most expensive of them 本题有正确答案吗?

1. twice as expensive as
as....as中间加形容词的原级形式,如果有倍数,倍数放在as...as的前面
2。B 原理同上
3。A 两个东西比较,选有the的,表示特指贵的那一个,这里不是最高级或者比较级。

twice as expensive as

B

A

1,2两题都是在考 形容词/副词的比较级+AS+形容词/副词的原形+AS的结构用法

反正记住一点
这个结构只能用形容词的原级!!
