在通常情况下，some用于肯定句，而在否定句和疑问句中则改用any。如：There are some letters for you.有几封信是你的。
There aren't any letters for you.没有一封信是你的。
Are there any letters for me?有我的信吗?
但是，在下列几种特殊情况下却通常要用some而不用any：
1．希望得到肯定回答的疑问句通常用some。如：May I have some paper?我可以拿些纸吗?
Didn't he give you some money?他不是给了你一些钱吗?
Can you lend me some money?能借点钱给我吗?
Aren't there some stamps in that drawer?那抽屉里不是有几枚邮票吗?
2．表示请求或建议的疑问句通常用some。如：Why not give her some flowers?为什么不送她些花呢?
Would you like some bananas?吃点香蕉吗?
Won't you have some more?你不再要一点吗?
Shall I get some chalk for you?要我给你拿些粉笔来吗?
3．有时some用于肯定句和否定句均可，但意义有区别。如：I don't like some of the films.这些电影中有几部我不喜欢。
I don't like any of the films.这些电影中我一部也不喜欢。
4．与表示否定意义的few或little连用，表示肯定意义，其意为“不少”“相当多”。如：Some few students were absent today.今天有不少学生缺席。
He spent some little money on books.他花不少钱买书。
注：不要将some few / some little理解为“相当少”。
