    Social customs and ways of behaving change all the time. Things that were considered impolite many years ago are now acceptable. Just a few years ago, it was considered to be impolite behavior for a man to smoke on the street. No man who thought of himself as being a gentleman would make a fool of himself by smoking when a lady was in the room.

    Customs also differ from country to country. Does a man walk on the left or the right of a woman in your country? Or doesn't matter? What about table manners?

    The Americans and British people not only speak the same language but also share a large number of social customs. For example, in both America and England, people shake hands when they meet each other for the first time. Also most Englishmen will open a door for a woman or offer their seats to women, and so will most Americans. Promptness(及时) is important both in England and in America. That is, the dinner guest either arrives close to the time that has been made or calls up to explain his delay(耽误).

    The important thing to remember about social customs is not to do anything that might make other people feel uncomfortable—especially if they are your guests. There is an old story about a man who gave a very formal dinner party. When the food was served, one of the guests started to eat his peas with a knife. The other guests were amused or greatly surprised, but the host calmly picked up his knife and began eating in the same way. It would have been bad manners to make his guest feel foolish or uncomfortable.

    Tea bag drinking is most Westerners' favorite way of drinking tea. Do you know how it came about?

    The tea bag was invented in 1908 by Thomas Sullivan, an American tea seller. He was sending out free tea in silk(丝绸) bags for people to try. People put the bags together with the tea leaves into the cup and added hot water. The tea tasted good, and people thought it was easy to clean the cup. They were not happy when Sullivan started sending them loose(散的) tea again.

    Sullivan realized that he had a hot new thing in his hands, and he built a machine to pack the bags.  As tea bags became popular, they were changed from silk to gauze(薄纱) and later paper. In 1952, Lipton Tea made the tea bag even more popular with its invention of the four-sided tea bag. Tea bags were soon a hit in the UK, and today 85% of tea in the UK is packed in paper bags.

    However, many people still prefer loose leaf tea. This is because some tea companies put not very good tea in their tea bags. But for most drinkers, tea bags are still the easy, tasty way to go.

    When summer is coming, you can often hear the news about the enterovirus(肠道病毒). It may not be a big deal to adults, but it has killed a lot of children.

    Children under 10 years old are easily infected but adults can also catch an enterovirus. If you feel sleepy, uneasy, tired and don't want to eat, you may have an enterovirus. In fact, it seems that you have caught a cold first. It's even hard for doctors to tell. But if you have blisters(水泡) in your mouth, doctors can almost be sure of it. The enterovirus is especially dangerous to children. If a child seems to have one, he or she should see a doctor right away.

    If you want to keep healthy and be away from the virus, here are some rules you should follow: Wash your hands often, and keep your house clean. Try not to go to the public places, like crowded night markets or hospitals. Of course, if your friends get an enterovirus, try not to contact(联系) them before they get well. If you do all these things, you will have little chance of getting it.

    The most popular food in America was invented because a cook got angry. George Crum was a cook at a restaurant in Saratoga Springs, New York. One day in 1853, a customer(顾客) who had ordered fried(油炸的) potatoes sent them back to the kitchen. He wanted the cook to slice(切) them thinner and fry them longer. George Crum had a bad temper(脾气), and he thought the potatoes were fine the way he made them. To teach the customer a lesson, he sliced potatoes very thin and fried them until they were crispy(脆的). But instead of being angry, the customer loved the new fried potatoes. He asked for more. Other people who tried them like them too, and customers kept asking for them. Far many years, people called them Saratoga chips after the town where they were first made.

    Even now, after more than 150 years, potato chips are very popular. At least one of every ten potatoes grown in the United States is made into potato chips. So if you like potato chips, be glad George Crum had a bad temper!

    Zheng Lin is a Junior 3 student in Shijiazhuang, Hebei. Earlier this month, Zheng and his classmates stood on the street with a box asking people for donations(捐款). Later they gave the money they got to the poor students in their school.

    Many Chinese students raise money to help people in need. Most of the time, they hold a box and ask for donations on the street or in the park. Or they sell things like old books and CDs. Those students have done a great job so far. The money helps the students in poor areas like Yunnan and Gansu with new clothes, pens and pencils.

Teenagers in the U.S. make donations, too. But they raise money in a different way—they raise money by doing something for others. For example, they sell homemade food or play musical concerts in their neighbourhood to raise money.

     "Chinese students like to wait for people to donate, or sell things that they buy with their parents' money," says Ge Daoshun, an expert. "While U.S. kids get donations and give people something useful in return."

    Ge says Chinese teenagers should learn to raise money in the U. S. kids' ways. "That way, they can show their talents and practice communication. More importantly, they can learn every coin counts(有价值). They have to work hard to get a donation."
