1、many people因为people是可数名词。
2、只是单数复数一样如果是不可数 就要用 much。
many和much的其他用法:
关于many of 和 much of:
(1) 其后接名词时,该名词通常应是特指的(比如有the, these, those, my, our, Tom's等修饰)。
如:
Many of the farmers grow rice.
很多农民种稻子。
(2) 如果名词没有表特指的限定词,通常就不用of。Many和Much的用法区别
如:
误:She didn't eat much of breakfast.
正:She didn't eat much breakfast.
她没有吃多少早餐。
(3) 如果用了介词of又没有特指限定词,通常是不可以的。
如:
误:Many of students have read it.
正:Many of the students have read it.
许多学生读过它。
