which 这是一句定语从句，介词in前置了。现在分析一下句子：整句句子简化：The English play was a great success。(我想这里是great吧) 很明显 ：先行词是The English play ，从in which my students acted at the New Year's party 这里是定语从句，修饰先行词The English play ，而was a great success则是句子剩下部分。至于为什么用in,则是一个固定搭配：act in the play意为“在戏剧中扮演角色”然后这里是把in这个介词提前了，其实句子还可以表示为 ：The English play which my students acted in was a great success。那场由我学生扮演角色的英语短剧很成功。像这种把介词提前的例子还有：The man with whom you shook hands just now is head of our department。The room in which my family live used to be a garage。可能一开始看这样的句子比较不习惯，不过很快就会习惯的~~祝你好运~~~。
