题目内容
9.---Your parents bought you _____ books last year,right?---Yes._________ them is 20.( )
| A. | the number of; a number of | B. | the number of; the number of | ||
| C. | a number of; the number of | D. | a number of; a number of |
分析 ---你的父母去年给你买了大量的书,对吧?
---是的,是20本.
解答 答案:C.a number of大量的,后可加可数名词复数.the number of…表示…的数量,谓语动词用单数,故选C.
点评 A number of"的意思是"若干"或"许多",相当于 some 或 a lot of,和复数名词连用.当它出现在主语前时,谓语动词和主语搭配.必要时,还可以加上形容词great,large,small,good 等.例如:
A number of highly qualified scholars have worked in Singapore.
"The number of"和"a number of"一样,跟在后头的名词也是复数的,不同的是这里的主语是单数的 the number,不是它后面的复数名词,谓语动词必须和 the number 呼应,如:
The number of undergraduates has increased over the years.
