—How many students are there in your school?
—_______ students, I think.
A. Three thousands
B. Three thousand
C.Three thousands of

答案

B

解析

试题分析：此题考查名词的量。确切数量常用数词+hundred/thousand/million/billion+名词的复数形式；不确切数量常用hundreds/thousands/millions/billions + of+名词的复数形式.根据语境可知选择B。
点评：区分确切数量和不确切数量的表达方式，有几个关键点要分清楚。确切数量必须要有基数词,且量词不能用复数形式；不确切数量的量词必须要有复数形式，且其后一定要加介词of。只要掌握好这两点,确切数量和不确切数量的问题基本解决。
