Question

【题目】 I can never forget the day ___________ we worked together and the day ___________ we spent together.

A. when; which B. which; when

C. what; that D. on which; when

Answer 1

【答案】A

【解析】两个先行词the day都是表示时间的名词，但第一个空白处要填的关系词在从句中作状语，因此要用关系副词when。第二个空白处要填的关系词在从句中作动词spent的宾语，因此要用关系代词which或that 来引导定语从句。
