the time _ I stayed in the country with those farmers.解析定语从句中不缺主语，也不缺宾语，从句中缺时间状语，因此需用关系副词when来引导从句。答案when5_ is reported in the newspaper，the war between the two countries has come to a stop.解析当非限制性定语从句放在句首时，只能用as引导；当as在从句中作主语时，后面常接动词的被动语态。答案As6Lu Xun，_ real name is Zhou Shuren，wrote lots of novels and essays.解析关系词在从句中作定语，用whose。答案whose7Can you think of another example _ this phrase

Can you think of a piece of clothing that is inseparably linked to American culture? Your answer would be blue jeans.Levi Strauss did not invent jeans，but he is considered the first person to make and sell great numbers of them.He was born in Bavaria，an area that today is part of Germany.In 1847 he and his family immigrated to the United States.Levi Strauss opened a small dry goods store，first in New York，then in San Francisco，California.Among the products he sold were jeans.These pants were especially useful for miners in California.They needed clothing made from a strong material.Jeans are usually made from a heavy cotton cloth called denim.Levi Strauss partnered with a clothing maker named Jacob Davis.Davis had invented a process for making rivets for jeans.These little metal connectors helped hold the pieces of cloth together to make the jeans stronger.In 1873，the government gave Strauss and Davis a patent for their invention.That meant no one else could legally copy it without their permission.In 1928，the Levi Strauss company registered the word “Levis” as a trademark for their product.The Smithsonians National Museum of American History in Washington has one of the oldest known pairs of Levis.Writer James Sullivan published a book called Jeans: A Cultural History of an American Icon.In it，he says jeans represent two American values: creativity and rebellion.Cowboys wore jeans in the old Wild West.In the 1950s，people saw famous Hollywood actors like James Dean and Marlon Brando wearing jeans in movies.Today jeans still come in blue but also lots of other colors.They can also differ widely in price.You might find jeans for 15 dollars in an American discount store.However，they can also sell for thousands of dollars a pair.Some people like to buy jeans that look fresh and new.Others like to buy new jeans that are torn and look old.What kind of jeans do you like?
