选择题
．Have you considered the students’ request _________ the school library _______ more books on popular science?
A．that; provide
B．when ; provided
C．which; should provide
D．where; would provide
答案
答案：A
考查同位语从句和虚拟语气，第一空填that引导同位语从句，that不做成分，指起到连接作用，对request进行说明，第二空填provide，省略了should，因为同位词是request，同位语从句用虚拟语气，Sb （should）do.选A。
