Different countries have different customs. When you are in different countries, you should follow their customs.

In China, it's impolite to talk when eating dinner. And you`re not supposed to start eating first if there are older people at the table.

Very often people who travel to the United States forget to tip(付小费). It is usual to tip waiters, taxi drivers and porters who help carry your bags. Waiters expect to get a 15% tip on the cost of your meal. Taxi drivers expect about the same amount.

In England, make sure to stand in line even if there are only two of you. It's important to respect(尊重) lines there. It's a good idea to talk about the weather. It's favorite subject of conversation with the British.

In Spain(西班牙)，it's a good idea to have a light meal in the afternoon if someone invites you for dinner. People have dinner very late ,and restaurants do not generally open until after 9:00 pm.

 In Saudi Arabia(沙特阿拉伯)，men kiss one another on the cheek(脸颊).Your  host may welcome you with a kiss on both cheeks. It is polite for you to do the same.

In Japan, people usually give personal or business cards to each other when they meet for the first time. When a person gives you a card, don't put it into your pocket(口袋) as soon as you get it. The person expects you to read it.

Don't forget to be careful of your body language to express something in conversations. A kind of body language that is acceptable in one culture may be impolite in another.

    Most English people have three names: a first name, a middle name and the family name. The family name comes last. For example, my full name is Jim Allan Green. Green is my family name. My parents gave me both of my other names.

    People don't use their middle names very much. So "John Henry Brown" is usually called “John Brown”. People never use Mr., Mrs. or Miss before their first names. So you can say John Brown, or Mr. Brown; but you shouldn't say Mr. John. They use Mr., Mrs. or Miss with the family name but never with the first name.

    It is different from Chinese names. In China, the first name is the family name, and the last name is the given name. For example, a man called Zhou Jian puts his family name Zhou first.

    Mark Twain tells a boy's story in The Adventures of Huckleberry Finn. Huck is a poor child without a mother and a home. His father drinks too much alcohol and always beats him.

    Huck's situation frees him from the restriction of society. He explores in the woods and goes fishing. He stays out all night and does not go to school. He also smokes. Huck runs away from home. He meets Jim, a black man who has escaped(逃脱)slavery(奴隶制).They travel together on a raft(木筏)made of wood down the Mississippi River. Mark Twain started writing" Huckleberry Finn" as a children's story. But it soon became serious. The story tells about the social evil of slavery, which is seen through the eyes of an innocent child. Huck's ideas about people are formed by the white society in which he lives. So, at first, he does not question slavery. Huck knows that important people believe slavery is natural and this is the law of God. So he thinks it is his duty to tell Jim's owner where to find him.

    Later, Huck comes to understand that Jim is a good man. He finds he cannot carry out his plan to inform Jim's owner of his whereabouts(下落). Instead, he decides to help Jim escape. He decides to do this, even if God punishes him.
