That evening,which I will tell you more about That evening,which I will tell you more about about later,I ended up working very late.句子结构详细分析下,还有为什么要用which.when为什么不可以?≧﹏≦≧﹏≦≧﹏≦
这样说吧which 是引导定语从句的关系代词,它在定语从句中必须充当一个语法成分 在I will tell you more about later这个定语从句中,which是宾语,意为tell you more about which 换成when就变为tell you more abou when了。so。。。
