     (1) Although we may not realize it, when we talk with others we make ourselves understood not just

by words. We send messages to the people around us also by body movements. A smile and handshake

(握手) show welcome. Waving one's hand is to say "Goodbye." Nodding the head means agreement, while

shaking it means disagreement. In China and some English-speaking countries, these body movements have

the same meanings.

     But not all body languages mean the same things in different countries. For example, nodding the head in

some Asian countries means not "Yes." but "No:"

     When we speak a foreign language, (2) to know the meanings of the body movements is important in-the

foreign countries. In Russia, France and some of South American countries men kiss (吻) each other when

they meet. Men don't kiss each other in China or English-speaking countries. In England, older people usually

shake hands when they meet someone for the first time, however, young people don't shake hands. (3) In

France, people shake hands in the office every morning. French people kiss each other more often than English

people when they meet or leave.
