Question

Have you considered the students’ request ______ the school library ______ more books on popular science?

1. A.
   that; provide
2. B.
   when ; provided
3. C.
   which; should provide
4. D.
   where; would provide

Answer 1

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。
