This is the book for which he is looking 这句话正确吗？

有书上说look for这样的词组不可分开，可应用书上有This is the book for which he is looking这个例句，糊涂了，求解

This is the book for which he is looking.（错误）
固定搭配之中的介词不可提到定语从句的关系代词前面。

“应用书”上写错了。尽信书不如无书。

把for调到最后：is this the book which he is looking for? 最好把时态统一，把was 也改为is 

This is the book for which he is looking.是错误的。 固定搭配之中的介词不可提到定语从句的关系代词前面 应为： this is the book that he is looking for.

定语从句一般结构为介词+which,可以将介词提到which前面来。
