Body language is used by people for sending messages to one another. It is very useful because it can help you make yourself easily understood.When you are talking with others,you are not just using words, but also using expressions and gestures.For example, waving one's hand is to say "Good-bye." A smile and handshake show welcome, and clapping hands means congratulations. Nodding the head means agreement, but shaking the head means disagreement.The gestures are accepted both by Chinese and foreigners as having the same meanings.

　　身势语是用来帮人们传递信息的，身势语非常有用，因为它可以使对方很容易地明白你自己的意思。我们同别人谈话时，并不仅限于用言语来表达，我们还用表情和身体的动作来向对方表达要传递的信息。例如：挥手表示“再见”，微笑和握手表示欢迎，拍手表示祝贺，点头表示同意，摇头表示不同意。这些手势对说汉语的人和说英语的人来说，都具有相同的意思。
