Question

14. As a result of destroying the forests,a large

of desert covered the land.

   A. number;has   B. quantity;has

   C. number;have   D. quantity;have

Answer 1

14. B

14. B解析:句意:破坏森林的结果是大片沙 漠覆盖了陆地。

a large number of后面要 接复数名词，a large quantity of后面可接 可数名词复数，也可接不可数名词，因desert 在此处用作不可数名词，谓语动词须用 单数形式has covered。
