为什么不可以说Increasing people went to the square.

问题描述:

为什么不可以说Increasing people went to the square.
为什么必须是an increasing number of people?
为什么increasing可以直接修饰population,但修饰people时必须加number?
有什么规律吗?
是不是抽象名词用increasing修饰,都要加number等单位词?

因为increasing population中的population解释为 the / a number of people了,所以就不必说:
an increasing number of population.
