    This week, our topic is pollution. What are the answers to all of our pollution problems? We asked two experts to give their views.

    ◇Forest Smith is a member of Green First, an environmental group.

    Our future on the Earth looks very bad. We are dumping waste on our land. We can't breathe the fresh air. The sea is polluted too.

    I visited some relatives recently in a small village. They grow their own food and cycle everywhere. They are not wealthy, but they are happy and healthy.

    We must close the factories producing useless products. That will reduce rubbish and air pollution. We must recycle more, give up all cars, and improve public transport.

    A big problem is overpopulation in big cities. We must give up big cities and factories, and go back to a simple way of life.

    ◇John Green is a scientist at a university.

    Things are not as bad as Forest says. We'll have a bright future. We don't need to give up cars but we need to invent better, cleaner engines.

    This won't stop the problem of traffic jams. So we need better public transport. We should also recycle more.

    But some things are getting better. My sister returned last month after living abroad for five years. She said, “Our old neighbourhood doesn't look the same as before－it is cleaner and greener now.”

    In a word, science has brought many improvements to our life.

    Do you have a beautiful dream? What are you going to be when you grow up? Almost everyone has their own dreams in their life. The dreams are very important to them. The dreams can make them work harder.

    Wu Jun is studying in a school now. His dream is to be a teacher in West China. Many children there want to go to school but they can't. Their families are very poor and their parents don't have enough money to send their children to school. But going to school and studying is the only way to change their life. Teachers are greatly needed there, so he wants to be a teacher to help them. He will be kind to his students and make friends with them. He will give them love and teach them how to be a useful person. He thinks it is the greatest job in the world.

    No one knows exactly when jazz was invented, or by whom. But it is said that it began in the early 1900s. Jazz was a new kind of music, for America and the world, and New Orleans was its birthplace.

    Who were the jazz pioneers? Most were blacks. This music was not written down, and at first only blacks played it. It was hard for white musicians to learn the new style. But soon they, too, were playing jazz.

    The popularity of this music spread. From New Orleans, it traveled up the Mississippi to Chicago, then to Kansas City and New York. By the 1920s, there were many jazz musicians, both black and white. Many of them were famous. One man was better than the rest. His name was Louis Armstrong.

    Louis Armstrong was a born musician. He was not only talented but also hard-working. He also had a good sense of humor and a big, good-natured smile. These personal qualities were valuable in his rise to fame. After he became famous, he traveled around the world. It seemed that everyone wanted to hear Louis play. But life was not always easy, especially at the beginning.

    Louis Armstrong was born in 1900 in New Orleans. His father never went to school and his mother could hardly read. When Louis was still a kid, his parents separated, and Louis lived with his mother. Their hard life can hardly be imagined. And yet Louis smiled through everything. He later wrote, "My whole life has been filled with happiness. Life was there for me and I accepted it. Whatever happened has been beautiful to me. I love everybody."
