小学六年级英语(深圳朗文版)下册 Unit 1 Being polite-I（在线收听）
Listen and read.
People all over the world shake hands for many different reasons.
We shake hands when we meet new people or during special
festivals. Athletes often shake hands before or after games.
Business people shake hands when they make a deal!
Why do we shake hands? Why don't we shake feet? A long time ago,
most people carried knives or guns. When people did not want to
fight, they showed their empty hands. Maybe people shook hands so
they could not hide knives in their sleeves. Later, hand-shaking
became a sign of peace.
Today we don't have to worry about people with guns and knives but we
still shake hands a lot! The reason is simple --it's still a sign of friendship.
