(A) addictive from (B) addictive and (C) addictive or (D) between addictive or(A) (E) among addictive or 答案是A,但是我有一点不理解的 1,distinguish X from Y, 这里的X,Y都必须是平行的事物,addictive的词性只有形容词,不能作名词和nonaddicitive drugs做比较, 2,distinguish between X and Y, 是OG中间说过的固定用法,distinguish among也是一种固定用法,如果是distinguish among drugs,addictive and nonaddicitive做形容词修饰,这样是不是更好呢? |
