题目内容
19.In this club,a number of basketball players from the USA.The number of them 30.( )| A. | is,are | B. | are,is | C. | comes,are | D. | come,are |
分析 在这个俱乐部,许多篮球队员来自美国.他们的数量是30个.
解答 答案:B.
a number of表示"许多",相当于 many,修饰可数名词复数,作主语时,谓语动词用复数.number前可用large,small等修饰,以表示程度; the number of表示"…的数量",跟复数名词连用作主语时,中心词是number,谓语动词要用单数;根据a number of basketball players from the USA.The number of them 30,可知前面用be动词的复数形式are,后面用单数形式is.故选B.
点评 做本题的关键是熟练掌握the number of 与a number of 的区别.
