【考点】说明文；学校生活．

【答案】Body Language    We often use body language in our daily life.I'd like to tell you something about it in China.
   When we meet each other，we often smile and shake hands.What's more，when we agree with each other，we will nod our heads.However，when we have different opinions，we will shake our heads instead.More importantly，when we are in class，we should sit up and also raise our heads.Eye contact is a very important part of body language.But to be polite，don't look at the older people's eyes for a long time.To make a good impression on others，you should smile at others when talking with them.We also need to listen carefully.
   I hope my advice will help you and you can have a good time in China.
