问题描述：
I will never forget the time when we worked on the farm.when 为什么可以转化为 during which?
when which 不是用于定语从句的吗?为什么又变成了during which?
问题解答：
我来补答
I will never forget the time when we worked on the farm
=I will never forget the time during that time we worked on the farm
=I will never forget the time during which we worked on the farm
好好琢磨一下吧
再问： during 难道是从during that time 移到后面而来的？能解释一下吗？？非常感谢了！！！
再答： 我绝不会忘记那段时光，（在那段时间里）我们一起在农场工作 during that time = during which 也即，which相当于 that time
再问： 哦.....明白了 原来是这样 还有疑问：All the neighbors admire this family，——the parents are treating their child like a friend. A why B where C which D that 为什么选B不选其他的？？？
再答： 这个题中where=in which（即 in this family） A 意思不符 C,D前应加 in 所以只能选B 翻译：邻居都很羡慕那个家庭，（在那个家庭里）父母对待孩子就像对待朋友一样
