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.

51. About Luke Ravenstahl, which of the following statements is correct?

A．He is the youngest mayor in the U.S.A.

B．His family background has contributed to his successful political career.

C．His young age has won support from media and young voters.

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

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

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

53. 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.

54. Where can you find this article?

A. A magazine B. A brochure about politicians

C. A newspaper D. An advertisement about some mayor candidates

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

A. Distrust from his citizens B. pressure from other outstanding young majors

C. economical standstill of his city D. decreasing population in his city

本文是一篇新闻报道，讲美国一名市长因为就任年轻所面临的一系列振兴经济以及赢得选民信任的挑战。

51. B 细节理解题。由第一段cashing in on his family’s political tradition可知，选项B正确；由第一段第二、三行可知，他只是major city最年轻的州长，而Small towns还有更年轻的州长，排除选项A；由第一段末句可知他并未已经获得媒体和青年选民的支持，排除选项C；由倒数第二段可知，他不一定任期到209年，他还必须面临次年的选举，排除选项D。

52. A 词义猜测题。由语境可推知句意为“一旦选民看到他的职业道德，对他年龄的顾虑自然就消失了”，故dissipate表示“消失”之意。

53. C 细节推断题。A项文中并未提到；B项与第二段第二行的事实正好相反；C项在第三段第三行有交待；由第一段第四句可知，10万人口是指Tallahassee，而不是Pittsburgh，再说文中是over，与选项中的smaller也不符，选项D错。

54. C 推理判断题。文段首PITTSBURGH, Sept. 7是新闻最明显的标志。

55. B 细节理解题。由第一段末句和第二段前两句可知，选项A正确；由第二段the brink of bankruptcy 和第三段第一句可知，C项正确；由第三段第二句可知选项D正确。

Holding a cell phone against your ear or stalling it in your pocket may be hazardous to your health．

This paraphrases a warning that cell phone; manufacturers include in the small print that is often tossed aside when a new phone is purchased．Apple, for example, doesn't want iP hones to come closer to you than 1．5 centimeters; Research In Motion, Blackberry's manufacturer, recommends 2.5 centimeters．

If health issues arise from cell phone use, the implications are huge．Voice calls - Americans chat on cell phones 2．26 trillion minutes annually - generate $109 billion for the wireless carriers．

Devra Davis, an epidemiologist who has worked for the University of Pittsburgh, has published a book about cell phone radiation, "Disconnect." The book surveys scientific research and concludes the question is not settled.

　　Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20-to-29 age group and a drop for the older population.

　　"Most cancers have multiple causes," she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer.

　　Children are more vulnerable to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid. No studies have yet been completed on cell phone radiation and children, she says.

　　Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiofrequency radiation had damaged DNA in their brains.

　　Ms. Davis recommends using wired headsets or the phone's speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen.

Andrew Carneigie, known as the King of Steel, built the steel industry in the United States, and, in the process, became one of the wealthiest men in America. His success resulted partly from his ability to sell the product and partly from his policy of expanding during periods of economic decline, when most of his competitors were reducing their investments. Carnegie believed that individuals should progress through hard work, but he also felt strongly that the wealthy should use their fortunes for the benefit of society. He opposed charity, preferring instead to provide educational opportunities that would allow others to help themselves. “He who dies rich, dies disgraced”, he often said. Among his more noteworthy contributions to society are those that bear his name, including the Carnegie Institute of Pittsburgh, which has a library, a museum of fine arts, and a museum of national history. He also founded a school of technology that is now part of Carnegie-Mellon University. Other philanthropic(慈善的) gifts are the Carnegie Endowment for International Peace to promote understanding between nations, the Carnegie Institute of Washington to fund scientific research, and Carnegie Hall to provide a center for the arts. Few Americans have been left untouched by Andrew Carnegie’s generosity. His contributions of more than five million dollars established 2,500 libraries in small communities throughout the country and formed the nucleus of the public library system that we all enjoy today.

A new study suggests that the more teenagers watch television , the more likely they are to develop depression (抑郁)as young adults. But the extent to which TV may or may not be to blame is a question that the study leaves unanswered.
The researchers used a national long-term survey of adolescent health to investigate the relationship between media use and depression . They based their findings on more than four thousand adolescents who were not depressed when the survey began in 1995.
As part of the survey, the young people were asked how many hours of television or videos they watched daily. They were also asked how often they played computer games and listened to the radio.
Media use totaled an average of five and one-half hours a day. More than two hours of that was spent watching TV.
Seven years later, in 2002, more than seven percent of the young people had signs of depression. Their average age at that time was twenty-one.
Brian Primack at the Universtiy of Pittsburgh Medical School was the leading author of the new study . He said every extra hour of television meant an eight percent increase in the chances of developing signs of depression.
The researchers say they did not find any such relationship with the use of other media such as movies, video games or radio. But the study did find that young men were more likely than young women to develop depression given the same amount of media use.
Doctor Primack says the study did not explore if watching TV causes depression . But one possibility, like sports and socializing. It might also interfere with sleep, he says, and that could have an influence.
The study was just published in the Archives of General Psychiatry. In December, the journal Social Indicators Research published a study of activities that help lead to happy lives. Sociologists from the University of Maryland found that people who describe themselves as happy spend less time watching television than unhappy people. The study found that happy people are more likely to be socially active, to read, to attend religious services and to vote.
60．The average age of the depressed young people should be_______when they began to receive the survey.
A．21           B．15              C．14                D．20
61．According to the passage, which of the following can possibly lead to depression?
A．Swimming                           B．Attending a party
C．Attending religious services             D．Watching TV for a long time.
62．We can learn from the passage_______.
A．the survey lasted a short time
B．over 280 teenagers who received the survey became more or less depressed in 2002
C．men are more likely to become depressed than women
D．the study about the relationship between media use and depression was published in the journal Social Indicators Research
63．What is the best title for the passage?
A．Teens, television, depression
B．Depression—the common problem of teens
C．Problems of watching TV
D．Teens—a group enjoying watching TV

Findings from a new study were presented at a recent meeting of the American Psychosomatic(身心的) Society. Researchers in the United States studied 100,000 women during an eight-year period, beginning in 1994. All of the women were fifty or older. The study was part of the Women’s Health Initiative organized by the National Institutes of Health.
The women were asked questions measuring their beliefs or ideas about the future. The researchers attempted to identify each woman’s personality eight years after gathering the information.
The study found that hopeful individuals were 14% less likely than other women to have died from any cause. The hopeful women were also 30% less likely to have died from heart disease after the eight years.
Hilary Tindle from the University of Pittsburgh in Pennsylvania was the lead author of the report. She said the study confirmed earlier research that linked optimistic feelings to longer life.
The researchers also gathered information about people’s education, financial earnings, physical activity and use of alcohol or cigarettes. Independent of those things, the findings still showed that optimists had less of a chance of dying during the eight-year period.
Some women who answered the questions were found to be hostile (怀敌意的), or highly untrusting of others. These women were 16% more likely to die than the others. They also were 23% more likely to die of cancer.
The study also found women who were not optimistic were more likely to smoke and have high blood pressure or diabetes. They were also more likely not to exercise.
Tindle says the study did not confirm whether optimism leads to healthier choices, or if it actually affects a person’s physical health. She also says the study does not prove that negative (消极的) emotions or distrust lead to bad health effects and shorter life. Yet there does appear to be a link that calls for more research.
