people可数?是much people 还是many people为什么?

people可数吗?在英语中 是用 too much people 还是 too many people 是many people还是much people? Not much people?还是Not many people? 是too many people 还是 too much people "people"是可数还是不可数?是用much还是many来修饰? people 应该用many people 还是much people呢? a great many people中a为什么能修饰people?great是修饰many还是people? many people 还是much people .语法知识也要,英语 people前面用much还是many people 用的是too many people 还是too much people?我已是混淆啦,呵呵, 是how much people……还是how many people…… 是so much people还是so many people 请说明原因
