回答第 22 題至第 25 題：     The life of Levi Strauss is a US success story. A German who immigrated to America in 1847 at age
nineteen, Levi Strauss began by selling needles, thread, and buttons in New York. On the invitation of his brother-in-law, he sailed to San Francisco in 1853.
    Gold had been discovered in California a few years before, and the Gold Rush had begun. The population exploded as more and more people came to try to get rich overnight. Suddenly, thousands of people started mining for gold. Strauss noticed that the miners complained that their pants were always tearing easily and that the pockets ripped apart as soon as one put a few nuggets in them.
    Levi Strauss saw a business opportunity. He began making pants out of some heavy brown canvas he had brought to use for tents or wagon covers. These new pants were stiff, but they sold briskly. When the original fabric was used up, Strauss went to Europe for more. What he got was a lighter, more flexible fabric from Nîmes, France, called serge de Nîmes. This cloth, which became known as denim, proved even more useful for pants, since it was just as strong but much more comfortable. With indigo, the pants were dyed the familiar blue color.
    Miners still complained about problems with their pockets. On the advice of Nevada tailor Jacob Davis,Strauss went to a blacksmith and had the jeans pockets reinforced with metal rivets. In 1873, they patented the popular innovation. The rivets, along with the patterned stitching on the hip pockets, became Levi trademarks.
