A group of students at Sunshine School are holding a charity sale to raise money to help their classmate Lisa. Lisa had cerebral palsy (大脑性瘫痪) when she was a baby. People who have cerebral palsy have trouble walking. Although Lisa has to use a wheelchair (轮椅) to help her get around, she never gives up.

    "Lisa has the chance of standing up, but she needs an operation (手术)," Lisa's doctor said.

    "I never thought that I could stand up one day. Actually the news is surprising for me. However, when I see my parents are worried about the cost of the operation, I am sad. I don't mind if I can't stand up," Lisa said. "Now my classmates and some other kind people are helping me. I am really thankful."

    "While helping Lisa, we can also learn a lot. We have learned how to cook cookies (曲奇饼) and how to sell them," Betty, one of Lisa's classmates said. "Now we know making money is not easy, so we won't waste money anymore."

    Alex, a boy in Lisa's class, told a reporter that they could raise about $100 every day. "We have raised about $2,100 so far. We hope we will raise more money for Lisa's operation," he said.

    Charles Dickens was an English writer. He was born in 1812. He created some of the world's best-known characters and many readers think he is the most important writer of the Victorian era (1837-1901). Some of his famous novels are Oliver Twist, David Copperfield and Great Expectations. Most people in his novels lived in London.

    In 1824, Dickens' father went to prison(监狱) because he couldn't pay money to someone. In those days, a man's wife and young children went to prison with him. Charles was 12, so he left school to work in the prison. Life was hard, and a lot of children worked in those days. Dickens' own experience helped him to write about poor children without a mother or father. Dickens' success began with the publication (出版) of The Pickwick Papers in 1836. And his book Oliver Twist is about a boy without father. Important people were more interested in the problems of poor people after reading Dickens' books.

    Dickens' novels are often very long and he wrote them in different parts for a newspaper each week. His novels have a lot of exciting and sad things in them. He wanted his readers to buy the newspaper every week. And the readers wanted to finish the story! Dickens' novels are popular because many of his stories are about social(社会的) problems and family life. Dickens was successful in writing and he has been praised by other writers for his style and characters.

    Calvin needs to go to New York for a meeting this Saturday. It's sunny. It's his first time to go to New York, so he doesn't know his way(路) around New York. The meeting is in Peterson Building on 34th Street and it starts at ten o'clock. He wants to get there on time, so he asks two American boys for help.

    "Excuse me, could you tell me where 34th Street is?" asks Calvin.

    "Sure," answers one of the boys." It's not far from here. And you can just walk along this street and turn left at the first crossing. Then you can see it on your right."

    "No. Don't listen to him. He is not telling you the right place. You can just take the No.7 bus and get off at the third stop," says the other boy.

    Then the first boy says, "OK. But the third stop is not 34th Street. It's 35th Street."

    At this time, Calvin finds that there's only five minutes left(剩下). Then he gets into a taxi(出租车) and leaves. After that, Calvin thinks he should ask a policeman for help next time.
