Question

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

Answer 1

C

試題分析：考查倍數(shù)的表達：倍數(shù)+as+adj+a/an+as結構， 30％是倍數(shù)， as low a price as 是固定搭配，不能調換詞的順序的。句意：這些二手商品比之前的要便宜百分之三十。選C。
點評：本題考查倍數(shù)的表達：除了：倍數(shù)+as +adj+as，還有：倍數(shù)+比較級+than，倍數(shù)+the+名詞+of，倍數(shù)+從句，這題有兩個特殊，一是倍數(shù)用百分比來表示，而是as…as中間的結構是固定結構，做題時按照句子的結構來選擇。
