智 课 网 G M A T 备 考 资 料 GMAT语法知识点之number用法-智课教育 本文主要就number/numbers 用法这一GMAT语法知识点做介绍，给大家参考。 几种用法之间区别：非核心词与核心词；number的意义；numbe r与相关成分的单复数一致关系。 1) a number of / numbers of + 可数名词复数 + 动词复数 可以理解为量词结构，a number of表示一些，numbers of表示 大量。of后面的复数名词才是核心词，谓语动词因此总是复数 Manystudents arrived early, but only a number of them worked on their exercises.
