有个关于英语从句的问题?
i am here to find ways in which they might communicate with each other better.
这句话的连词为什么是in which,用which不行么?
还有一些类似的词,像of which,to which之类的,怎么用这些连词,

答案

which 指的是 前面的 ways.
In (this) way they might communicate with each other better.
In 某种 way 意为 用/通过 某种 方式.
of which和to which是需要看前后文的,习惯搭配之类的.
