英语中的分数做主语时，它是单数还是复数根据什么判断

Answer 1

英语中的分数做主语时，它是单数还是复数根据它所修饰的中心名词是否为可数名词而定
Three
quarters
of
the
population
_____
(be)Chinese.
are
population
单独使用时,为不可数名词,谓语动词用单数;但是一旦前面有百分数或分数短语修饰时,就视为可数,谓语动词用复数
There
fourths
of
the
money
_____(have)
been
spent
on
books
has
money
为不可数名词,所以谓语动词用单数

Answer 2

根据分数所修饰的名词
如果该名词是可数名词则用复数
不可数名词则用单数
Three
quarters
of
the
population
are
Chinese.
There
fourths
of
the
money
has
been
spent
on
books.
population是可数名词
money是不可数名词
