Question

【题目】–– What are you looking for?

–– I’m looking for the book _______ you bought last Sunday.

A. who B. when C. that

Answer 1

【答案】C

【解析】句意：——你正在寻找什么？——我正在寻找上周日你买的那本书。who引导定语从句,修饰人，作定语从句的主语或宾语；when引导定语从句，作状语；that引导定语从句，修饰事物或人，作主语或宾语。此处修饰的先行词the book是事物，作定语从句谓语bought的宾语，故用that引导定语从句，故选C。
