题目：I'll never forget the day ____ which I joined the soccer team.
其中要填的是on,但是我不是很明白，希望有人可以帮忙解释解释。
语法不是太好，希望大家帮忙造几个句子比较好理解。
还有in which和on which的区别是怎么用的？
有人说why=for which
where=in which
when=during which
whose=of which
但是在这题中应该是when的意思吧，那为什么用on?
详细必定加分，明天晚上前希望得到答案。
详细的会加分的。
谢谢大家了。
首先你要明白which引导的是定语从句，只是所用介词的不同。例句先行词是 day, 意为I joined the soccer team on the day. 在具体的某一天 用on .下面的例句用in whichHe left the house in which he was often beat by his step-father when he was a child.he wasbeat by his step-father in the house. 其他几个也是类似。你可以自己分析分析
