    William Lindesay, a British traveler and writer, has been exploring the Great Wall—one of the human's most wonderful building projects. Not even a Chinese knows the Great Wall of China as well as he does.

    When, as a schoolboy, Lindesay announced his plan to explore the Great Wall, nobody took him seriously. But Lindesay achieved his goal, by spending 25 years on the Great Wall and has become one of the world's most famous experts on its rich history. Lindesay now lives and works in Beijing. This year his new book has come out, The Great Wall Explained, with a lot of photographs and articles.

    Running on the Great Wall was a brave trip and Lindesay had already run 3,000 kilometers along it! During those years, he got to many villages along the way. He was often helped by friendly villagers, although they didn't quite understand why the Englishman would have such interest in the Great Wall.

    When you are learning a language, listening, speaking and writing are important, but reading can also be very helpful. When you read, you can not only learn some new words, but also learn how to use them. When you read a passage, it gives you a good example for writing. Here are some good reading tips.

    Firstly, try to read at the right level (水平). Read something that you can understand. If it is too hard for you, it is not interesting.

    Secondly, try to understand the new words. If there are four or five new words on a page, don't use a dictionary. Instead, try to guess their meanings as you read. Mark (作标记) them with a pencil. Then look them up in a dictionary when you finish reading, and write them in your own vocabulary book. Try to remember them.

    Thirdly, try to read for a short time once a day. Fifteen minutes or half an hour every day is better than two hours every Sunday. For example, you can read before you go to bed, or after you get up or at lunchtime.

    Lastly, read something that interests you. Choose a newspaper, a book or a magazine about a subject that you like. It will be easy enough for you to understand.

    In common with many countries, Britain has serious environmental problems. In 1952, more than 4,000 people died in London because of the smog. The government introduced new laws to stop smog from coal fires and factories and the situation improved a lot.

    Today, London is much cleaner but there is a new problem: smog from cars. Part of the problem is the new "out of town" shopping centers. In the past, people often walked to shops near their home. Now, many people drive to the new shopping centers. So, the small shops have disappeared and more people have to travel to do their shopping.

    Critics (批评家) think that Britain needs cheaper public transport. An early morning train trip from Glasgow to London (about 600km) can cost about £100, for example. A 15-minute bus trip can cost over £1. 00.

    Many people are trying to reduce the use of cars in Britain. Some cities now have special bicycle paths and many people cycle to work. Some people also travel to work together in one car to reduce the pollution and the cost.

    In America, some teenagers are interested in charity. They are willing to help others. Some teenagers even set up their own charity group. Shreya Papneja is one of them.

    Shreya Papneja is 13 years old. She started a charity group called Children's Health Awareness Program in Schools. Her charity group helps kids make healthy choices and tries to stop childhood obesity(肥胖).

    A doctor once told Papneja that more than one-third of children were overweight. She did a lot of research about it. Then she made a website to teach other children about exercise and healthy eating.

    She does a lot of things for her charity group when she is free. For example, she often organizes different activities at schools around her hometown.

    I know how hard it is to make a change, but I won't give up. At least I've changed a lot. Now I eat more healthy food instead of junk food," she said to a reporter.
