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
考查同位語從句和虛擬語氣，第一空填that引導(dǎo)同位語從句，that不做成分，指起到連接作用，對request進行說明，第二空填provide，省略了should，因為同位詞是request，同位語從句用虛擬語氣，Sb （should）do.選A。
