融合性关系副词引导的从句

假如动词是不及物动词，融合型关系副词都可以换成介词+融合型关系副词吗？譬如：

You should put it where they are.

一般是如此。请看外刊例句：

1. Sometimes they put it in where we leave it out

2. Cavell is less interested in where Sophia's path ends than in where it begins.

3. What type of homes do people live in where it is cold most of the year?
