Hey Anna). Over here in England it would most likely mean ; Imagine you have a secret. And you wanted to keep it a secret, because if don't you would be in trouble. Then, one day, by chance or by mistake you are about to reveal the secret. Someone who also knew the secret wants to warn you that you were about to do so would say : " Don't give yourself away " or ( it's not likely at your age but...)) You are hiding in a cupboard with someone)). Playing hide and seek. Hide and seek is where one person from a group closes their eyes and counts to one hundred. While he or she is counting everyone else runs away and hides and the person counting has to try and find them when they have finished counting. So... ) you're in a cupboard with someone and you are getting bored waiting to be found by the person who was counting and decide to peep out of the door to see if the 'seeker' is nearby. The other person in the cupboard would whisper..." No, no don't give yourself away " ie ...they will see you when you are peeping) I hope that makes sense mate)) I'm sure there must a lot about England and the English language that doesn't make sense to someone from China)). It's a funny old world eh?)) Good luck with your studies)

It depends on the context; it could be give yourself away as in "revealing something about you" , as in " give up the fight" or as if you are a really selfless person and you give yourself away to help other people. So , if you tell us the sentence we could tell you what exactly means on that particular context. =)
