问题 选择题
(2014重庆一中高三下第三次月考)13. There are many smokers in China, _____ the number of students who pick up this habit _____ increased a lot.
   A. where; has
B. which; has
C. where; have
D. as; have
答案

答案:A

本题第一空考察的是定语从句,先行词是China,后面的定语从句句子结构很完整,所以使用关系副词where来引导这个定语从句。第二空是定语从句的谓语动词,因为主语是the number of…该结构做主语的时候,谓语动词使用单数形式。故A正确。
