Question

As a result of destroying the forest, a large ________ of desert ________ covered the land.

A．number; has

B．quantity; has

C．number; have

D．quantity; have

Answer 1

B

考查主谓一致：第一空填quantity，因为a number of修饰可数名词，第二空填has，因为a large quantity of修饰不可数名词，谓语和quantity的数保持一致，句意是：由于森林的毁坏，大量的沙漠覆盖了土地。选B。
