America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while — then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families.

    Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily.

    Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don't show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves treated hospitably.

    For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!

    Generations of Americans have been brought up to believe that a good breakfast is one of life's essentials. Eating breakfast at the start of the day, we have all been told again, is as necessary as putting gasoline in the family car before starting a trip.

    But for many people the thought of food as first thing in the morning is by no means a pleasure. So despite all the efforts, they still take no breakfast. Between 1977 and 1983, the latest year for which figures are available, the number of people who didn't have breakfast increased by 33 percent-from 8.8 million to 11.7 million-according to the Chicago-based Market Research Corporation of America.

    For those who feel pain or guilt about not earing breakfast, however, there is some good news. Several studies in the last few years indicate that, for adults especially, there may be nothing wrong with not taking breakfast. “Going without breakfast does not affect performance,” said Arnold E. Bender, former professor of nutrition（营养）at Queen Elizabeth College in London, “nor doegiving people breakfast improve performance.”

    Scientific evidence linking breakfast to better health or better performance is surprisingly inadequate, and most of the recent work involves children, not adults. “The literature,” says one researcher, Dr. Ernesto Pollitt at the University of Texas, “is poor.”

    It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can't fix the damage. Sometimes they are afraid to try something. to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain.

    Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.

    Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He made the monkeys' blood back to the monkeys' brains. When the brain's temperature was 10℃, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.

    To foreigners Chinese food isn't a meal. It's an experience. Failing to order the right food and struggling with chopsticks are only parts of the adventure every time I sit down in a restaurant.

    In one of our favorite Sichuan restaurants, it took 3 waiters and 15 minutes for us to order only our drinks. I simply wanted water, but my dad wanted to try the fresh juice they had listed on the menu. There were two problems, however. There were neither pictures nor English on the menu. After several hand gestures, he ended up ordering just a coca cola to simplify things.

    One of our most embarrassing moments was at Xiabuxiabu, a very famous hotpot chain. As soon as we walked in, the entire restaurant seemed to stare at us. Uncomfortable already, we had the most difficulty ordering our meal, since there were so many steps to the whole process. Fortunately, the waitress was very patient and successfully gave us our food. Although it was not the best food I had in Beijing, it was certainly entertaining dropping things into the boiling pot of soup. Once, I tried picking up a dumpling to show my father and dropped it onto his pants. I looked behind me, and people were laughing secretly at my chopstick skills.

    No matter how many difficulties we have regarding food, our experiences give the best stories to tell. The servers are always understanding of our situation and their friendliness is exceptional. They always greet us with a big smile even when they realize they have to clean up the noodles slipped through our clumsy chopsticks.

    Many years ago, there lived a poor fisherman. His only companion was his dog. They might be seen walking on the white sandy beach.

    The dog was always beside his master as the fisherman made his little boat ready to sail. When the man pulled out to sea each morning, the dog would run up on the high ridge (山岭). There he would sit and watch all day. The dog never moved until late afternoon when he saw the little boat return. Then he would race back to the shore to greet his master.

    As the years went by, the fisherman grew older. So did the faithful dog. The fisherman still went out to sea. The dog still watched for his return, sitting on the high ridge.

    One early morning in September, the fisherman was getting his little boat ready. All at once the dog began to bark. He circled around the fisherman and tugged at his trousers. The fisherman could not remember when he had seen his dog act so strangely. He patted the dog's back, thinking the dog wanted to play. But nothing made any difference. Then the man climbed into the boat and sailed away. The dog went to his watching place, still barking.

    There were other fishing boats out that morning. Suddenly the soft wind changed. It began to blow wildly. The fisherman's boat was seized by the wind and whirled around (随风旋转) .The sky darkened. Rain began to fall.

    "It's a hurricane!" said the fisherman." The man thought of his dog at once. Had the dog left the ridge and run home? Or was he still sitting there? The fisherman tried to drive his boat and turn it toward the shore. Suddenly a great wave swept over his head and tossed the boat away (卷走).

    The next morning, the hurricane was over. The families of the other fishermen ran to the shore. They watched for the return of the boats. They waited and waited, but no one returned. Then the people went slowly back to their homes and started a new life. As they rebuilt their village, no one gave a thought to the fisherman's dog.

    Several months later a group of villagers was out gathering sea grapes (海葡萄). They noticed what appeared to be the figure of a dog sitting high on the ridge.

    "Look" said one." Isn't that the old fisherman's dog?"

    "How could it be, after all this time?" said another.

    When the man reached the spot, he found only a rock—a rock shaped like a dog. But as soon as the people looked up again, they saw the stone dog. He just sat there on top of the ridge, waiting, waiting…

    Do you think the United Kingdom and the United States are alike? Winston Churchill once joked that the people of Britain and the people of America are separated only by their language. Do you think that is true? The British and the Americans both speak English as the official language. However, each uses some different words. We Americans are similar to the British. After all, our country was once owned by the UK,so we have a lot in common. But there are many differences between us.

    The UK has a king or queen, and the leader of the government is the Prime Minister. The US has no kings or queens. Our leader is the President.

    Both the British and Americans use pounds and ounces, pints, quarts, and gallons. Both use miles, yards, and feet. Our money is different, though. The British use pounds and pence. Americans use dollars and cents.

    Driving in a car is very different in the UK. They drive on the left side of the road. We drive on the right. What we call the hood of the car, the British call the "bonnet". British cars run on "petrol", which we call gasoline.

    In our everyday life, we do many of the same things as the British. But we describe them differently.

    A young mother here might push a baby in a baby carriage. A British mum pushes a "pram". The British watch "telly", while we watch TV. We like to eat French fries, but the British call them "chips". Millions of Americans drink coffee, but most British prefer tea.

    So we are different in many ways. But we stay friendly anyway.
