题目内容

A number of students ______ playing on the ground but I don't know what the exact number______.
A.are; isB.are; areC.is; isD.is; are
A

试题分析:a number of一些,许多;the number of……的数目。句意:许多学生正在操场上玩,但是我不知道确切的数目是多少。结合语境可知前文主语为复数形式,故系动词用复数。下文主语number表示抽象含义,故谓语动词用单数,选A。
点评:由number构成的这两个短语是经常考查的对象,其一般解题原则是先区分这两个短语的含义,然后结合语境选择正确答案。其结构,含义比较固定,熟记即可。
