答案是C.in which
该定语从句所修饰的先行词The English play在从句中的成分是作为状语的介宾短语in the English play当中的宾语.该从句的原句是：my students acted in the English play...
这个方法适用于所有“介词+wh-“的判断,即通过还原从句,看先行词前面应该用什么介词.
另一个问题：whom是代替宾语的关系代词,who既可以代替主语也可以代替宾语,现代英语中普遍用who代替whom,但是在“介词+whom"形式中一般不能用who代替.

答案是C。这是个后置定语从句，如果把顺序正过来应该是my students acted ----the english play at the NEW Year's party was a great success.翻译过来：我的学生在新年晚会上演的英语剧非常成功。“in the paly 是指“在剧中”符合上下文的意思。

没有答案，正确的答案应该是which ,定语从句。。。其中有一个答案是正确的。。。什么叫没有答案！就是要你选一个嘛！这是2004年全国模拟卷的一道题目。难道出一道题目，你跟老师说没有答案吗？无语！sorry ,我没看清楚，应该选C，因为act 与in搭配，意为扮演，这个是定语从句，可以还原为my students acted in the English play at the New Year...

C. in the English play = in which, 在该剧中，受 play的影响。
两个原则：
如果不是固定搭配或习语，根据前面的“先行词”来决定：
e.g. I attended a meeting at which I remained silent. at the meeting = at which
I cleaned the table on which there was some leftover food. on the table = on which
其次，固定搭配或习语里固有的介词，就不可改变：
Look at the abandoned baby, of whom the community workers are taking care.
( take care )of the abandoned baby = of whom
Look at the abandoned baby after whom the community workers are looking.
(look) after the abandoned baby = after whom
Look at the girl who's speaking in class. 不可以用宾格关系代词：whom,因为在定语从句中需要做主语（主格关系代词）：...who's speaking in class. 不可说：...whom's speaking in class.
Look at the girl for whom you're looking. 此处不可说：...for who you're looking. 直接在介词后的，必须是宾格关系代词。
但是，如果不把for 提到前面，而是留在句末，两种形式都行。
即在口语中，常用主格的who代替宾格的whom， 虽然whom更为正式。
Look at the girl whom/ who you're looking for.
