If someone says to you, “give me five”, don't give five yuan to him! It will make others laugh! The person isn't asking for your money, but your fingers.

In the U.S.A, “give me five” or “give me the high five” is a good gesture(手势). You can see it often in films or on TV. It means the slapping (拍打)of each other's right hands together. People do it when something happy happens. For example, if a student does well in exams or gets No. 1 in his school sports meet, he will give high fives to his friends to celebrate.

Who did this gesture first? Why did he do that? It may come from the old Roman (古罗马的) gesture of raising(举起)the right arm for the emperor(皇帝). This showed that the person raising his arm had nothing in his hand and he couldn't hurt the emperor.

Why not try to give the high five to your friends?
