some和any都代表一些，那么他们怎么区分呀？

some用肯定句 any用否定

THERE ARE SOME PEOPLE ON THE FIRLD

THERE IS NOT ANY PERSON ON THE FIELD

一般来说，肯定句用some，否定句和疑问句用any，但也有特殊情况
1。很自信对方会有肯定回答或表示建议的时候就算是问句也用some
Would you like some tea? 来点儿茶吗？
2。any在肯定句里表示任何一个
I've been to any city in China
我去过中国的所有城市

some用于肯定句 any用于否定句

some 一般用在肯定句中，不过也有特殊的场合中也用some
eg: Do you have some water?
any 一般用在一般疑问句中的
eg: Is there any chair in the classroom?
