Question

38.As a result of destroying the forests,a large ______ of desert _____ covered the land.
\x05A.number,has B.quantity; has C.number,have D.quantity; have

Answer 1

答案：B
翻译：由于森林的破坏/毁灭,大量的荒漠覆盖了大地.
1.desert为不可数名词,所以不能用a large number of修饰,它只能修饰可数名词复数.
如：There are a large number of students in our school.
由此排除AC；
2.a large quantity of 既可以修饰可数名词,也可以修饰不可数名词.
且quantity短语做句子主语时,谓语动词的数采用就远原则,即和quantity保持一致.
如果quantity是单数,则谓语动词也用单数形式；如果是复数quantities,则谓语动词用复数形式.
如：A large quantity of water is in the bottle.
Large quantities of water are in the bottle.
很明显,句中为单数quantity,所以谓语动词也用单数B has (covered),排除D.
3.综上所述,正确答案为B.
