问题选择题

You’d better go there by train. The train ticket is ________ the plane ticket.

A．as cheap three times as

B．as three times cheap as

C．three times cheaper than

D．cheaper three times than

答案

答案：C

考查倍数表达。倍数表达的基本结构：

1. “A+倍数+形容词或副词的比较级+than+B”，表示“A比B大（长、高、宽等）多少倍”。

2.“A+倍数+as+形容词或副词的原级+as+B”，表示“A正好是B的多少倍”。

3. “A+倍数+the size/height/length/width， etc+of+B”，表示“A正好是B的多少倍”。

4. “……times+what+从句”。

选项ABD结构有误，故选C。
