I’ll never forget the time when (=on which) we worked on the farm.

题目

I’ll never forget the time when (=on which) we worked on the farm.
Do you still remember the afternoon when (=in which) we first met three years ago?
为什么一个用in which,一个用on which?

答案

这与介词跟名词的搭配有关, 我们说:in the afternoon , at the time
故第二句的when (=in which),第一句when (=at which), on which 不准确,因为一般不说on the time .
