阅读下面短文，并用英语回答问题(请注意每小题后面的词数要求)。
A greeting is a way of saying “Hello” to someone.People in different countries greet each other in different ways.The following are some examples.
In the United States，people usually shake hands.The handshake has an interesting origin(起源)．It started long ago as a way of showing people that you weren't carrying a weapon(武器)．Shaking the person's right hand while looking him or her in the eye is the usual way.
Handshakes are also common in other parts of the world，including Britain and Russia.In Russia，a man often holds another man's hands very strongly during the handshake.Most people in New Zealand also greet each other by shaking hands.However，the Maori(毛利人) people in New Zealand greet each other by pressing their noses together.
In other countries，such as France and Belgium，hugging and kissing are more common when two people meet.In those cultures，people kiss each other on the cheek(面颊)．The number of kisses is different from country to country.In Saudi Arabia(沙特阿拉伯)，men might hug and kiss each other(but not with a woman) on the cheek.In some eastern countries，including Japan，bowing is the traditional way of greeting people.The strangest custom，though，is probably in Tibet，China.People there usually stick out(伸出) their tongues(舌头) to greet others.
