All those second-hand goods are sold at

问题选择题

All those second-hand goods are sold at before.

A．30% as lower price as

B．as 30% low price as

C．30% as low a price as

D．30% lower price than

答案

题目分析：考查倍数的表达：倍数+as+adj+a/an+as结构， 30％是倍数， as low a price as 是固定搭配，不能调换词的顺序的。句意：这些二手商品比之前的要便宜百分之三十。选C。

点评：本题考查倍数的表达：除了：倍数+as +adj+as，还有：倍数+比较级+than，倍数+the+名词+of，倍数+从句，这题有两个特殊，一是倍数用百分比来表示，而是as…as中间的结构是固定结构，做题时按照句子的结构来选择。
