  [1] Have you ever been in the situation where you really didn’t believe what someone was saying? Did you have a sense that something didn’t ring true or a feeling that all was not right? Perhaps they were saying ‘‘Yes’’ yet their heads were shaking “No”.

[2]  The difference between the words people speak and our understanding of             comes from non-verbal communication, otherwise known as “body language”. Body language includes body movements and gestures(1egs,arms,hands,head and body),posture,muscle tension,eye contact,skin coloring,even people’s breathing rate and sweat.Additionally,the tone of voice,the rate of speech and the pitch of the voice all add to the words that are being used.

[3]   By developing your awareness of the signs and signals of body language,you can more easily understand other people,and more effectively communicate with them.There are sometimes subtle(微妙的)—and sometimes not so subtle—movements,gestures, facial expressions and even shifts in our whole bodies that indicate something is going on.We have ways of talking,walking,sitting and standing and they all say something about us,and whatever is happening on the inside can be reflected on the outside.

[4]By becoming more aware of this body language and understanding what it might mean,you can learn to read people more easily.This puts you in a better position to communicate effectively with them.What’s more, by increasing your understanding of others,you can also become more aware of the messages that you convey to them.

[5] There are times when we send mixed messages—we say one thing yet our body language reveals something different.This non-verbal language will affect how we act and react to others,and how they react to us.Therefore,in order to communicate more effectively,we should learn the signs and signals of body language correctly.
