Question

The number of the workers in this factory______about five hundred.One third of them ______woman teachers.
A,are are Bis are C is is D are is
我想问一下分数one third和单复数之间的关系,ONE THIRD走什么数是复数还是单数,还有是按one third作主语还是按them作主语 为什么

Answer 1

B,这里 前面的分数是主语,of them 是定语 of +名词、代词 一定是定语 修饰前面的名词 这是of的用法决定的.汉语意思是 他们中 的 三分之一.谁是主语很显然吧
但是分数作主语时谓语动词和of后面的名词保持一致,of后面的名词为复数可数名词,动词用复数形式；of后面的名词为单数可数名词或不可数名词,动词用单数形式
