Body language is the quiet, secret and most powerful language of all! It is said that our body movements communicate about 50 percent of what we really mean while words only express 7 percent. So, while your mouth is closed, your body is just saying.. Arms. How you hold your arms shows how open and receptive(能容纳的) you are to people you meet. If you keep your arms to the sides of your body or behind your back, this suggests you are not afraid of anything. Outgoing people generally use their arms with big movements, while quieter people keep them close to their bodies. If someone upsets you, just cross your arms to show you're unhappy! Head. When you want to appear confident, keep your head level（水平）. However, to be friendly in listening or speaking, you must move your head a little. Legs. Your legs will move around a lot more than usual when you are nervous or telling lies. Posture (姿势). A good posture makes you feel better about yourself. If you are feeling unhappy, you usually don't sit straight, with your shoulders inwards. This makes breathing more difficult and makes you feel nervous or uncomfortable. Face. When you lie, you might put on a false face. But that expression would not last long.  And your true emotions such as happiness, sadness, fear and so on will come through. 小题1: When someone is keeping his arms behind his back, he tries to tell you that .
