Some people seem to have unusual memories. Zheng Aiqiang, a "memory athlete" on TV show Super Brain, can remember 2,660 numbers in just one hour!

    You would think people like him must have special brains. But according to a recent study by researchers from America and Holland, the brain structure (结构) of ordinary people and 23 of the world's leading memory athletes shows no difference.

    Good memories can be trained. New research in the magazine Neuron suggests that a person will get a super memory with just six weeks of hard training.

    Researchers found that a technique (技巧) called loci, invented by the ancient Greeks, can greatly help improve memory.

    By using loci, you are using your imagination to improve the brain's memory networks. You can link (关联) something you need to remember with a place that you know very well. For example, to remember a list of numbers, imagine yourself walking through your house. Each thing is linked to a number. For example, zero could be the handle on the door and five could be the painting on the wall.

    In one study, some ordinary people were given 20 minutes to remember 72 nouns. At the beginning, they could only remember 26 words, but when they were taught loci, they could remember 62 words.

    "Not everyone can become a memory winner. But everyone using the technique can improve his memory greatly," said Boris Konrad, one of the researchers in the study.

Customs on Eating

    Food in China and western countries is different. China has about five thousand years' history. Chinese people may spend half of their time on food. They choose food very carefully. They only use fresh materials to make food. For example, they only eat fresh fish. Chinese people have a lot of ideas for cooking. They can cook a chicken in over ten ways. So Chinese food is very popular around the world. Western countries, like England or America, don't have fresh food because they buy their food from supermarkets. -They only sell stored materials. Western people also prefer fast food like hamburgers and chips. They are unhealthy for people's body. Western people are very good at making desserts and chocolates. They can make very good cakes and chocolates. These food are very sweet and can make people become fat quickly.

    In China, when people invite others for a meal, they would pay for the meal, but it's not the same way in western countries. In western countries, people will think you only invite them but don't need to pay for them. They won't be happy if you pay for them.

Another difference in eating is that: Chinese people use chopsticks but western people use knives and forks.

    Chinese people only have three meals in a day. But western people may have more. They usually have afternoon tea when they would have fruit or cakes with cheese.

    It was Saturday again. Grace and Karen disliked Saturdays. That was another thing the twins had in common. They shared the same clothes and tied their hair in the same manner. In fact, it was hard for their classmates and teachers to tell the difference between them sometimes.

    Unlike their classmates, they had to get up early at seven every Saturday to prepare for their lessons. Grace had to attend the art lesson and Karen had to attend her ballet lesson. "How I wish I could do something different today," said the twins with one voice. All at once, an idea came to Grace and Karen at the same time. "What about exchanging our roles for a day?" they asked each other. It seemed like a wonderful plan. After giving each other a description of their own friends, Grace put on Karen's ballet dress while Karen put Grace's brushes and paints into her bag. Then they left for their classes.

    When the art lesson started, Karen was lost. Unlike Grace, Karen was poor at drawing. When the art lesson finally ended, Karen didn't dare to hand in her work.

    Meanwhile, Grace had problems in the ballet class as well. As she had no idea about the dance steps, she had to follow her classmates blindly. As a result, she kept knocking into them. Their ballet teacher became impatient with her, "Karen, you should remember the basic steps."

    When Karen and Grace got home, they were tired out. They decided that they would never try to be someone else they were not. It seemed that the grass was not always greener on the other side.

    Mr Brown was at the theatre. He had got his ticket at the moment, so he had not been able to choose tis seat. He now found that he was in the middle of a group of American ladies, some of them middle-aged and some of them quite old. They clearly all knew each other well, as before the curtain went up on the play they bad come to see, they all talked and joked a lot together.

    The lady sitting on Mr Brown's left, who was about sixty years old, seemed to be the happiest and the most amusing of the American group, and after the first act(幕)of the play, she apologized to him for the noisiness of her friends. He answered that he was very glad to see American ladies so obviously enjoying their visit to England, and so they had a friendly talk. Mr Brown's neighbour explained what they were doing there.

    "You know, I have known these ladies all my life, "she said. " We all grew up together back in our hometown in the United States. They have all lost their husbands, and call themselves the Merry Widows(寡妇). It is a sort of club, you know. They go abroad every summer for a month or two and have a lot of fun. They always go everywhere together. I have wanted to join their club for a long time, but I didn't qualify(具备……的资格)for membership until the spring of this year. "
