【题目】I have reached a point in my life _______ I am supposed to make decisions of my own.
A．which B．where C．how D．why
在线课程【答案】B
【解析】考查定语从句。句意：我已经到了应该自己作决定的那种境况了。先行词point和定语从句被介词短语in my life隔开，从句不缺成分，故判定先行词在从句中作状语，point在定语从句中作状语，关系副词用where。how不能用来引导定语从句；which在定语从句中作主语或宾语；why引导定语从句时先行词应为reason；因此可排除选项A、C和D。
