Put the books back ________ they belong after you have finished them．

Put the books back ________ they belong after you have finished them．

A.where

B.to where

C.to which

D.to the place

答案及解析： A

where引导状语从句，引导词在从句中作状语；B项搭配有误；C项为定语从句引导词结构，但是前面没有先行词；D项介词to应该改成in且place后面加上where。belong to后接名词，而不是副词、介词，故选择A项。
