【题目】We saw a new play at the theatre, ______________ we had supper at a restaurant.
A. after whichB. which afterC. then whichD. and that after
在线课程【答案】A
【解析】
考查介词+which引导的非限制性定语从句。句意：我们在剧院看了一部新戏，然后在一家餐馆吃了晚饭。分析句子we had supper at a restaurant可知，主谓宾完整，有地点状语，但缺少表示时间的状语，故用表示时间的after“在…之后”，which指代前面句子。故选A。
