To my understanding, a high school graduate has already reached a point in his/her life he/she is supposed to make decisions of his/her own.

A. which

B. where

C. how

D. why

答案：

A. which

(答案→)B. where

C. how

D. why

解析：考查定语从句。先行词 point是特殊的地点名词，从句中缺状语，故 point在从句中作地点状语，使用关系副词where。句意：我的理解是，高中毕业生已经到了他或她应该自己做决定的这样一个位置。
