Today we’ll talk about the history of blue jeans. For many people, blue jeans stand for (代表) American culture.
The history of blue jeans usually began with a man named Levi Strauss. He did not invent jeans. But he is the first person to produce and sell them in large numbers. Levi Strauss was born in Germany. In 1847, he and his family moved to the United States. He opened a small store and sold jeans. These pants were especially useful for miners (矿工) in California. They needed strong clothing. Levi Strauss worked with Jacob Davis, who had invented a step for making rivets (铆钉) for jeans. They helped make the blue jeans stronger.
In 1873, Strauss and Davis received a patent (专利) to own this invention. Nineteenth century workers would probably be surprised to know that their pants would one day become fashions. Today, jeans are worn by people of all ages. Jeans come in many colors other than blue and in many styles and prices. Fashion designers even create very costly jeans.
Writer James published a book called Jeans: A Cultural History of an American Icon (偶像). In the book, he says jeans serve as a sign for two American values, creativity and rebellion (叛逆).

Welcome to your favorite show－"Music Land" ! This month we are going to have some special shows on Bach, the Father of Music.
Johann Sebastian Bach was born in Germany(德国)in 1685. During his life, Bach wrote a lot of music for the church (教堂) and for his students, but he himself did not keep his own works(作品) carefully. Luckily, his second wife(妻子)saved them for him, so today we can still remember Bach through his music.
Bach married twice in his life and had 20 children. He loved his family very much. He wrote music for one of his daughters to tell her that too much coffee was bad for her health. I am now going to play a song for you from this interesting Coffee Cantata. And we will hear more about Bach after this song.
