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. How hard their life was can readily be imagined. And yet Louis smiled through everything. He later wrote, “My whole life has been happiness. Life was there for me and I accepted it. Whatever happened has been beautiful to me. I love everybody.”

Lin Wenqian is a girl student. When she was on a busy bus last month, she felt someone touching her. She was so afraid.

Zhou Bin, 12, is a boy. He likes to chat on the Internet. But once a stranger said lots of dirty things to him.Zhou was so surprised!

What can students do when this kind of thing happens? Here is some advice from some teachers and students:

Don't be afraid. Ask him or her to stop at once. If he or she doesn't listen, try to turn to others around you and call for help.

Keep calm. Be serious and keep a cool face. Say you don't like it and show you are angry.

If there is no one around, use clever ways. If you only shout or fight to make them angry, it could make things worse! They may take your life. Find excuses (借口) to run away. Say things like you are waiting for your parents or you want to go to the washroom.
