短文改错

     Although we may not realize it,  but when we talk with others we make ourselves understand not just

by words.We send messages to the people around us also by our expressions and body movement.A

smile and a handshake shows welcome.Wave one's hand is to say "Goodbye". Nodding head means

agreement when shaking it means disagreement.These gestures are received both by Chinese and English

speakers as having the same meaning.But not all body language means the same thing in different country.

Take nodding the head for example.In some Asia countries it means not "Yes" but "No".
