Millions of stars are travelling about in space. A few form groups which travel together, but most of them travel alone. And they travel through a universe which is so large that one star seldom comes near to another. For the most important part each star makes its journey in complete loneliness, like a ship on an empty ocean. The ship will be well over a million miles from its nearest neighbour. From this it is easy to understand why a star seldom finds another anywhere near it.
We believe, however, that some two thousand million years ago, another star wandering(漫游) through space, happened to come near our sun just as the sun and the moon raised its tides(潮汐) on the earth, so this star must have raised tides on the surface of the sun. But they were very different from the small tides that are raised in our oceans; A large tidal(潮汐的) wave must have travelled over the surface of the sun, at last forming a mountain so high that we cannot imagine it. As the cause of the disturbance came nearer, so the mountain rose higher and higher. And before the star began to move away again, its tidal pull had become so powerful that this mountain was torn to pieces and thrown off small parts of itself into space.
These small pieces have been going round the sun ever since. They are the planets.

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).
