at

on
选哪个介词,懂的来

Answer 1

答案：in which
分析句子结构如下：
1.主句为：The English play was a great success.
而该主句的主语The English play（即为先行词）被定语从句所修饰.
2.根据定语从句的语法要求,将先行词代入该从句,得：
my students acted (in the English play) at the New Year's party
= my students acted (in which) at the New Year's party
我的学生在新年晚会时在英语戏剧中演出.
3.很明显,该从句中的act是不及物动词,必须加介词in后,才能加代替先行词the English party的关系代词which做其宾语.
act in an English play 在一部英语戏剧中演出/表演
