The number of students in our school        4000 and a number of them     good at playing ping pong.

A．is, is

B．are, are

C．is, are

D．are, is

答案

C

解析

试题分析：我们学校学生的数目是4000，他们中许多人擅长打乒乓球。结合语境可知前文number表示数字，故be动词用单数。下文a number of them表达复数含义，故系动词用复数。选C。
点评：number of表示……数目，是抽象含义，不可数；a number of许多，表达复数含义，谓语动词用复数。熟记即可。
