case,point,situation等做先行詞

妳說的情況在定語從句中常出現。situation ，case ，point作先行詞時，關系詞壹般情況下用where。如：

I have reached a point in my life_where_I am supposed to make decisions of my own.

It's helpful to put children in a situation_where__they can see themselves differently.

其中有特殊情況的詞是point，因為它既可以表示地點，又可以表示時間。如《牛津詞典》上的例子：

We have reached the point 時刻；關頭；階段_when__we have no money left.

對比：

This is the point某地方；地點_at_which_the river divides。
