We should consider the students’ request________ the school library should provide more books on popular science.

A．that

B．when

C．which

D．where

答案

解析

试题分析：考查同位语从句，同位词是request，that引导定语从句对request的内容进行说明，句意：我们应该考虑学生的请求，学校的图书馆要提供更多的关于流行科学的书籍。选A。
点评：同位语从句的连接词that不做成分，只起到连接的作用，而定语从句的关系代词that，要做成分，做主宾表。要主语辨别。
