PITTSBURGH, Sept. 7 — At 26, many people haven’t even decided on a career. Luke Ravenstahl, cashing in on his family’s political tradition, is already the mayor of Pittsburgh, the youngest mayor of any major city in the country. Although mayors elsewhere have been younger, Jeff Dunkel was 18 in 2001 when he was elected mayor of Mount Carbon, small towns in New York, and elsewhere have also elected teenagers as mayors. But, Tallahassee, is the only other city with a population over 100,000 that has had a mayor as young as Mr. Ravenstahl. A supporter of Mr. Ravenstahl said concerns about Mr. Ravenstahl’s age would dissipate once the city saw his work ethic.

But now comes the hard part. As he strives to be taken seriously and take charge of a city only recently back from the brink of bankruptcy, the baby-faced mayor said that even the smallest decisions felt weighty, even what to wear in the Steelers game matters.

And another pressing issue is to strengthen the city’s economy. Pittsburgh has lost all its mills, nearly half its population and much of its downtown commercial district in the last several decades. “But Pittsburgh has 50,000 college students, and our challenge is to figure out how to retain them and to increase downtown development.” He said.

But one of the biggest uncertainties is how long he will remain in office. According to the city charter, Mayor Ravenstahl’s term will not expire until November 2009. Some city lawyers, however, have argued that he must face the electorate next year. And residents in Pittsburgh are still withholding judgment on him. Deli, Jimmy Cvetic, a sandwich shop owner, said “I call him Cool Hand Luke. He’ll be all right, but he’s going to need a cool hand to get through this.”

Mayor Ravenstahl said he was still coming to terms with the challenge he faced.

D. He will be mayor of Pittsburgh at least until 2009.

42. The underlined word “dissipate” in the first paragraph probably means________.

A. disappear                 B. appear                      C. spread               D. reduce

43. What can you infer from the article about Pittsburgh?

A. It is a small town in New York famous for steel mills.

B. It has always enjoyed prosperous economic success.

C. Many young college students there are the new hope of the district.

D. It is a major city in the U.S.A with a population slightly smaller than 100,000.

44. Where can you find this article?

A. A magazine                                  

B. A brochure about politicians

D. An advertisement about some mayor candidates

45. What kind of Challenges will not Luke Ravenstahl cope with?

Although the United States covers so much land and the land produces far more food than the present population needs，its people are by now almost entirely an urban society. Less than a tenth of the people are engaged in agriculture and forestry(林业), and most of the rest live in or around towns，small and large．Here the traditional picture is changing: every small town may still be very like other small towns，and the typical small town may represent a widely accepted view of the country，but most Americans do not live in small towns any more. Half the population now lives in some thirty metropolitan areas(1arge cities with their suburbs, of more than a million people each—a larger proportion than in Germany or England，let alone France). The statistics(统计)of urban and rural population should be treated with caution because so many people who live in areas classified as rural travel by car to work in a nearby town each day. As the rush to live out of town continues，rural areas within reach of towns are gradually filled with houses, so that it is hard to say at what moment a piece of country becomes a suburb. But more and more the typical American lives in a metropolitan rather than a small town environment．
