Question

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，求英语大神解答。

Answer 1

ways后面所跟的定语从句是固定用法，可以理解为一个词组的倒置，“in the way of...”“用...的方法”的意思。你问的都是接从句的连词，of which是指表示从属关系的从句，to which可以理解成“对。。。来说”的意思。其实用什么连词主要是看前面修饰的词。
那句话的意思可以翻译为：我想要找到能够彼此沟通的方法。

不知道我解释清楚了木有，希望对你有帮助哈。

Answer 2

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。

An incredible map of which countries emails each other. (a map of countries...)

Sharing the music track to which you're listening. (Listen to music track)

Answer 3

in which 指的是in ways，采用这些方法------
of which，to which主要看先行词，如this is the place in which he lives.因为Live是不及物动词，所以要加in，即lives in the place，当然可以用另一种说法，this is the place where he lives.这里面where= in which，因为where是副词，所以不能说live in where

Answer 4

这里的in which 相当于in the way,介词不能乱用,which 前的介词有时候是定语从句中动词短语的介词，如，This is the story of which he often hears.

Answer 5

在这一句中，ways 作为后面从句中的状语，即 they might communicate with each other 这一句中作状语。所以如果将从句补充完整为 they might communicate with each other in ways ... 所以 in 是必须的，转为定语从句时将 in 提到前面。
