in which定语从句

1。的确,in which可以等于when,也可以等于where,但不会等于why。关键是看定语从句中缺少时间状语还是地点状语。2。例如：1）I'll never forget these days in/during which I stayed with you。= I'll never forget these days when I stayed with you。我永远不会忘记我和你待在一起的日子。其中：in/during which I stayed with you = when I stayed with you = I stayed with you in/during which = I stayed with you in/during these days2）This is the city in which I stayed last year。= This is the city where I stayed last year。这就是那个去年我待的地方。其中：where I stayed last year = in which I stayed last year= I stayed in which last year = I stayed in the city last year。3。另外,有的in which找不到合适的关系副词代替。如：I dislike the way in which you treat me。我不喜欢你对待我的方式。其中：in which you treat me = you treat me in which= you treat me in the way4。for which = why如：Can you tell me the reason why you were late?= Can you tell me the reason for which you were late?你能告诉我你迟到的原因吗?其中：why you were late = for which you were late= you were late for which = you were late for the reason
