    Table manners are how to behave when you have a meal. They include how to handle knives, forks and spoons and how to eat in a polite manner. To behave well abroad, you should know some table manners.

    EATING MANNERS

    Japan: It is ＂perfectly＂ okay to slurp when you eat noodles. Unlike making big noises, slurping slightly is not rude. Japanese also say it tastes better if you slurp.

    Russia: Your wrists should be placed on the edge of the table while eating, fork in left hand, and knife in the right. It is not good manners to rest them on your lap. Keep your elbows off the table. Leave some food on your plate to show that the host has give you enough to eat.

    France: Never discuss money or religion over dinner. What is different from the manners in Russia is that finishing everything on your plate is considered good manners.

    Mexico: Whenever you catch the eye of someone who's eating, even a stranger, it's good manners to say ＂provecho＂, which means enjoy. In Mexico, dining is more than a meal. It's a social occasion — lunches are seldom quick and suppers can last for hours. Before you get seated, look for place cards, or wait until the host seats you. And you must say ＂enjoy your meal＂ before you leave the table.

    DRINKING MANNERS

    America: If you empty a bottle into someone's glass, it obliges that person to buy the next bottle. It's polite to put the last drops into your own glass.

    Australia: In a pub it's usual to buy a round of drinks for everyone in your group. When it's your turn, say ＂It's my round＂. When it's their round, they will buy it for you. Don't leave before you've bought a round.

    Japan: Don't fill your own glass of alcohol. Instead, you should pour for others and wait for them to do it for you.

    You may know the English letters A, B and C. But do you know there are people called ABCs? Do you know there is such a thing as "a banana person"? How strange! ABC means American-born Chinese. An ABC is a Chinese, but was born in the United States. Sometimes, people call an ABC a "banana person". A banana is yellow outside. So, when a person is a "banana", he or she is white inside—thinking like a Westerner and yellow outside—looking like a Chinese.

    Usually, ABCs know little about China or the Chinese language. Some of them don't speak Chinese. But if ABCs cannot speak Chinese, can we still call them Chinese people? Yes, of course. They are overseas(海外的)Chinese. These people may be citizens(公民)of another country like the US, Canada or Singapore. But they have Chinese blood. Their parents, grandparents or even great-grandparents were from China. They all have black eyes and black hair. But they are not Chinese citizens. They are people of the People's Republic of China. For example, we all know the famous scientist C. N. Yang(杨振宁). He got the Nobel Prize for Physics in 1957. Chinese people love him. But he is an American citizen.
