要看上下文才可以判断。 比如: 1.我们手里有一笔钱，在决定这笔钱放在谁那里时，是You hold this money的意思 2.要买什么东西时，我想让你付钱，就是You pay this的意思

It means you take this money. Analogously, "这本书你拿着" means "you take this book".

It just means "you take the money". Just like when we say "down sat the man" we emphasize"down".

It is a kind of inversion in informal oral Chinese.It means "you take this money".I guess the situation is the speaker is advising a person to take the money which should be taken by the person.
