(John, one of the exchange students, wants to buy something in Beijing. But he doesn't know where to go. Now he is asking Millie for help) John=J, Millie=M

J: Where can I buy some postcards, Millie?

M: Go to the bookshop in the shopping mall in Old Street. You'll find many postcards there.

J: Can you tell me how to get to the shopping mall?

M: Walk across the footbridge. Then walk along New Road until you see the traffic lights. Cross New Road, you'll see a restaurant. And the shopping mall is next to it.

J: Oh, I see! I also want to buy some souvenirs for my friends. Can I find some in the shopping mall?

M: You'd better go to the Souvenir Shop. It's very easy to find. Just come out of the shopping mall, you'll see the shop is at the other side of the street.

J: That's great! By the way, can I enjoy Beijing Duck in the restaurant?

M: Of course! The Beijing Duck in that restaurant is very nice.

J: Thanks a lot!

    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."

    Not only adults(成年人) but also teenagers have problems in their life. Here is a survey showing the main problems of teenagers.

    They feel stressed because they have too much homework to do both at school and at home. They have a lot of exams to take. And parents usually send them to different classes at weekends. They don't have their own time to do what they are interested in.

    Now more and more teenagers are getting short-sighted. They often read in bed or keep reading for a long time without having a rest. Some are crazy about playing computer games. Some spend too much time   (watch) TV. Another serious problem among teenagers is that many of them are becoming fat. They eat too much junk food and take little exercise.

    I think teenagers should think of ways to deal with (处理) the problems. They should make a plan for study and hobbies and find time to relax as much as possible.
