Body language is the quiet, secret and most powerful language of all! It speaks louder than words. According to specialists, our bodies send out more messages than we realize. In fact, non-verbal(非言语)communication takes up about 50% of what we really means. And body language is particularly important when we attempt to communicate across cultures. Indeed, what is called body language is so much a part of us that it's actually often unnoticed. And misunderstandings occur as a result of it.
