Question

一个英语问题

then he and his wife,jane,went horseriding,after which jane cooked their dinner in the microwave oven only to find their dismay that the had been destoryed

关键是after which，请解释用法，谢谢！

Answer 1

这是从文章中节选的一段话
句子成分大致是这样的
then【状语】 he and his wife【主语】,jane【插入语】,went horseriding【谓语】,after which jane cooked their dinner in the microwave oven【非限制性定语从句】 only to find their dismay that the had been destoryed【状语】
其中after which jane cooked their dinner in the microwave oven是一个非限制性定语从句，which指代前面的整个句子，即then he and his wife,jane,went horseriding这件事
所以这句话的翻译是：
然后，他和他的妻子jane去骑马，然后，jane在微波炉里做晚饭.......

Answer 2

这句话after which引导的是非限定性定语从句，先行词是前面的整个句子。整个句子作先行词时必须用which，而根据句意，Jane是在骑马后准备晚饭的，所以在前面加上after。
