    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.

    Mayme Clayton collected books， magazines and letters written by African Americans. Her son， Avery Clayton， thought her collection was important. Unlike most books， these were rare and hard to find. They were written by writers who helped shape African American culture.

    One book in the collection was written by Phillis Wheatley. Wheatley was a slave who wrote poetry. She was the first African American to publish a book. Wheatley herself signed (签名) the book in the Claytons' collection. No one else owns a copy signed by Phillis Wheatley.

    By the time she passed away at age 83， Mrs. Clayton had more than 30，000 books by or about black people. Her collection also includes papers about slaves， photographs， movies， sheet music， and personal letters by black leaders and artists. It is one of the biggest personal collections of African American history and culture in the United States.

    Avery Clayton's dream was to create a museum for his mother's treasures.  Scholars say that Mrs. Clayton's collection is very important. Without her work， part of African American heritage (遗产) would have been lost. “We didn't know these things existed，” says Sara Hadron of California's Huntington Library.

    The collections new home is likely to be in Culver City， California. Part of Avery Clayton's dream is to share the cultural riches his mother collected with others. He especially wants children to have a chance to see the collection. “ At present African American culture is being explained by pop culture，” he says， “ It's important to offer a more complete picture.”

    The "green" car has become popular in recent years. A green car is an environment friendly car. Today, most cars are powered (驱动) by petrol (汽油). They make our life easier. But cars have also made problems for the environment.

    There are a few new types of cars that use no petrol or a little petrol.

    Electric cars：This kind of car uses a battery (电池) for power. When you're not driving it, just plug it in like a mobile phone to power up the battery. They don't make exhaust (排放物). But car makers still can't make a battery that lasts for more than a few hours. That's why electric cars aren't very popular.

    Fuel cell cars (燃料电池车) : Fuel cell cars use hydrogen (氢) and oxygen (氧) to make power. The only exhaust they produce is clean water. But fuel cell cars are still much too expensive to make.

    Solar cars : This kind of car has large panels (板) on the top that take power from the sunshine. The car holds that power in a battery. Solar cars might be the cleanest of all. But no one uses them, because solar panels can't get enough power from the sun to make a car go for a long time. Also, they are very slow.

    Hybrid cars（油电混合车）： This kind of car is the most exciting kind, because it is very clean and not too expensive. The hybrid car is very smart: Half the time, it uses petrol, and half the time it uses a battery. So, when the petrol engine is working, it puts some of its power back into the battery. It uses much less petrol than other cars. It also makes less pollution for the environment.
