It's helpful to put children in a situation____they can see

where 在定语从句中做状语,where= in this situation,可以拆成两句话：It's helpful to put children in a situation；in this situation they can see themselves differently.若用which,前面要加in,in which=in a situation；把孩子们放到一个能够让他们从不同角度看待自己的环境中,这对于他们有所帮助.

因为这里只的是一种状态，所以用状语从句。

where，这里situation是抽象地点名词，也是定语从句的先行词，在后面的从句中在状语，所以用关系副词where
