题目

两个有关于Point的英语单选问题
I have reached a point __ for the first time my parents are letting me decide what major I'd like to choose.此句中横线处为何选when?
I still can't understand the point __ our math teacher explained in class.横线处为何选that?
要有详细说明,最好能全面总结一下从句中有point时对关联词的用法及选择方法.

答案

因为第一个point指的是“时点”、“时刻”,是个时间概念,所以用when；而第二个point指的是“知识点”、“观点”,所以用了that.
基本上就这两种情况,不用再总结了.
