Jeans are trousers made of a kind of clothe called denim. For many people, blue jeans represent American culture. The history of blue jeans usually begins with a man named Levi Strauss. Although he did not invent the jeans, he is considered the first person to produce and sell this kind of clothing in large amounts. Levi Strauss was born in Bavaria, Germany. In 1847, he and his family moved to the US. He opened a store, first in New York, and then in San Francisco, California. Among the products he sold were jeans. These trousers were especially useful for miners in California who needed clothing made of a strong material. Levi Strauss partnered with a clothing maker named Jacob Davis, who had invented a process for making rivets(铆钉) for jeans. These metal things helped strengthen the blue jean cloth to make the trousers stronger. In 1873, Strauss and Davis received a patent to officially own this invention. They began producing “ copper-riveted waist overalls(工装裤)”. In 1928 the Levi Strauss company used the word “Levi’s” as the trademark for their products. The 19 th -century workers would probably be surprised to know that their trousers would one day become a fashion object. Today, jeans are worn by people of all ages, incomes and lifestyles. Jeans come in many colors other than blue and in many styles and at many prices. A national museum in Washington, D.C. has one of the oldest known pairs of Levi’s jeans in its collection. Jeans have come to express different ideas about American culture based on the people who wear them. These include the heroes of the Wild West and famous Hollywood actors like James Dean and Marlon Brando in the 1950s. Writer James Sullivan published a book called Jean: A Cultural History of an American Icon. In the book, he says jeans serve as a sign for two American values, creativity and rebellion (叛逆). 小题1:This passage is mainly about _______.
