Arms· How you hold your arms shows how open and receptive(接受的)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‘ asking on whatever comes your way.Outgoing people usually use their arms with big movements while quieter people keep them close to their bodies.If someone makes you angry, just cross your arms to show you’re unhappy!

Head· when you want to show your confidence,keep your head level(平直).If you are monitor in class, you can also take on this position(姿势)when you want your words to be taken seriously. However, to be friendly in listening or speaking, you must move your head a little to one side.   

Legs.Your legs will move around a lot more than normal when you are nervous or telling lies.If you are at interviews, try to keep them still.
