One day when some government officials were rebuilding a house, they found a mouse hole in a corner and used smoke to make the mice inside the hole come out. A while later they saw mice running out, one after another，but they saw two mice didn’t run away immediately. It seemed that one was trying to bite(咬) the tail of the other.
Everyone was puzzled, so they came nearer to take a look. They realized that one of the two mice was blind, and the other was trying to allow the blind mouse to bite his tail in order to pull the blind one with him to run away.
During the meal time, they started to talk about the two mice. One serious American said, “I think the relationship between those two mice was that of king and guard.”
A smart Frenchman said, “I think the relationship between them was that of husband and wife.”
A Japanese said, “I think the relationship between them was that of mother and son.”
At that moment, one Chinese asked, “Why did those two mice have a certain relationship?”
Suddenly, they looked back at the Chinese. The American, the Frenchman and the Japanese who had spoken earlier all lowered (低下) their heads in shame, and didn’t answer.
In fact, the great love is not built on friendship or blood relationship. Instead, it is based on no relationship.
【小题1】The two mice didn’t go away immediately because _______.

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).
【小题1】 Why did Jacob use rivets for jeans?
