题目
题型:不详难度:来源:
– A number of students ____ in the dinning hall.
-- Let me count. The number of the students ____ about 400.
A.are, isB.is, areC.are, areD.is, is

答案
A
解析

试题分析:A number of一些,许多;The number of……的数目。句意:许多学生在大厅里面。——让我数一数。这些学生的数目是大约四百人。结合语境可知上文主语为复数名词students,故系动词用复数形式。下文主语为抽象名词number,不可数,故系动词用单数,选A。
点评:be动词往往根据句子的主语而有所不同,其应用原则可以结合如下歌谣来记忆;我用am,你用are;is用在他、她、它。单数名词用is,复数名词全用are。
