anyone,someone有咩分別? (緊急!!!)

In general we use some (also somebody/someone/something) in positive sentences and any (also anybody/anyone/anything) in negative sentences:

In most questions we use any. But we use some in questions when we expect the answer"'yes ". We use some in questions when we offer or ask things.

We also use any with the meaning "it doesn' t matter which ".

anyone is used in questions and in negative sentences (用於問句或否定句)

Anyone means any person.

Someone means some unknown person.
