— Yes. It is said that ________ the students is 300.
A.The number of ; a number ofB.A number of; the number of
C.The number of; the number ofD.A number of; a number of

答案
B
解析

试题分析:a number of一些,许多;the number of……的数目。句意:今年许多学生参加了三月十二日的植树活动。——是的,据说学生的数目是300.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B。
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。
