some more是用在肯定句中，any more是用在否定句和疑问句中，那为什么会有句子Would you like some more ?

some在这中句型中表达一种委婉语气。在表达征求意见并期待肯定回答时，尤其是请某人吃什么东西（常考题型），要用some代替any.

用some是希望得到对方的肯定回答，希望对方说yes,或者 I would like to have some```

如果用 any的话，对方会认为你虽然这么问，但是希望他/她回答 No， 不想给他吃

总之，希望得到对方肯定回答的疑问句里面都用some比较多

would you like some cake？
would you like some help?
would you like something to eat?

some表一些，any则是任何
从语义理解吧

人家客气
