两个明确英文

detailed and exact positive clear-cut specific这些词都可以表示“明确的”！

clear就行

one...theother...（后面不跟名词）表示“一个,另一个”（两者中另一个,一般有明确说明是两个时才用这个结构）注意与some+名词复数....theother+可数名词复数（=theothers）...的区别,表示“一些.,其余全部”one...theother....只有两个some...theothers...有三个以上例句：ihavetwobrothers,oneisshort,theotheristall.therearemanystudentsplayingintheplayground.somestudentsareplayingsoccer,theotherstudentsareplayingtennis.

definite object 明确的目标; [例句]Choose and define targeted market ( have a definite object in view)选择和界定目标市场（有的放矢）
