问题描述：
After four hours’drive,they reached ( )they thought was the place they had been dreaming of.
答案上是what,为什么不是where呢?
答
they thought 并不完整，需要WHAT指代那个地方
答
where 因为是指地方
答
they reached (what )they thought was the place they had been dreaming of.
首先 后面the place they had been dreaming of 定语从句,从句先不看
其次 they thought 做插入语,先不看
抽丝剥茧,剩下的就是what was the place做reach的宾语从句
而在从句中 what是做主语的,所以只能用what,where是不能做从句主语的
答
what 对应后面的place，place是名词，所以要用what
