第3篇 Attitudes to AIDS Now Most people say that the USA is making progress in fighting

AIDS, but they don\'t know there\'s no cure and strongly disagree that \"the AIDS epidemic is over,\" a new survey finds. The findings, released Thursday by the Kaiser Family Foundation, reassure activists who have worried that public concern about AIDS might disappear in light of recent news about advances in treatment and declines in deaths. \"While people are very optimistic about the advances, they\'re still realistic about the fact that there is no cure\" says Sophia Chang, director of HIV programs at the foundation. The Kaiser survey, like a recent USA TODAY Gallup Poll, does find that the number of people ranking AIDS as the country\'s top health problem has fallen. In the Kaiser Poll, 38% say it\'s the top concern, down from 44% in a 1996 poll; in the Gallup Poll, 29% say AIDS is No.1, down from 41% in 1992 and 67% in 1987. Other findings from Kaiser, which polled more than 1,200 adults in September and October and asked additional questions of another 1,000 adults in November: 52% say the country is making progress against AIDS, up from 32% in 1995.51% say the government spends too little on AIDS. 86% correctly say AIDS drugs can now lengthen lives; an equal number correctly say that the drugs are not cures.67% incorrectly say that AIDS deaths increased or stayed the same in the past year; 24% know deaths fell. Daniel Zingale, director of AIDS Action Council, says, \"I\'m encouraged that the American people are getting the message that the AIDS epidemic isn\'t over. I hope the decision-makers in Washington are getting the same message … We have seen signs of complacency.

第41题：What do activists worry about？

A) Recent news about AIDS is not true.

B) People may stop worrying about AIDS.

C) Deaths caused by AIDS may not decline.

D) Advances in AIDS treatment are too slow.

The Village Green in New Milford, Connecticut, is a snapshot of New England charm：a carefu

lly manicured lawn flanded by scrupulously maintained colonial homes. Babysitters dandle kids in the wooden gazebo, waiting for commuter parents to return from New York. On a lazy afternoon last week Caroline Nicholas, 16, had nothing more pressing to do than drink in the early-summer sunshine and discuss the recent events in town. “I don't think a lot of older people knew there were unhappy kids in New Milford, ”she said, “I could see it coming. ”

In a five-day period in early June eight girls were brought to New Milford Hospital after what hospital officials call suicidal gestures. The girls, all between 12 and 17, tried a variety of measures, including heavy doses of alcohol. over-the-counter medicines and cuts or scratches to their wrists. None was successful, and most didn't require hospitalization；but at least two attempts, according to the hospital, could have been vital. Their reasons seemed as mundane as the other happen-stances of suburban life. “I was just sick of it all, ”one told a reporter, “Everything in life. ”Most alarming, emergency-room doctor Frederick Lohse told a local reporter that several girls said they were part of a suicide pact. The hospital later backed away from this remark. But coming in the wake of at least sixteen suicide attempts over the previous few months．this sudden cluster—along with the influx of media—has set this well-groomed suburb of 23,000 on edge. At a town meeting last Wednesday night, Dr Simon Sobo, chief of psychiatry at the hospital, told more than 200 parents and kids, “We're talking about a crisis that has really gotten out of hand. ”Later he added,“There have been more suicide attempts this spring than I have seen in the 13 years I have been here. ”

Sobo said that the girls he treated didn't have serious problems at home or school. “Many of these were popular kids, ”he said, “They got plenty of love, but beneath the reassuring signs, a swath of teens here are not making it. ”Some say that drugs, both pot and‘real drugs’, are commonplace. Kids have shown up with LIFE SUCKS and LONG LIVE DEATH penned on their arms. A few girls casually display scars on their arms where they cut themselves. “You'd be surprised how many kids try suicide, ”said one girl, 17. “You don't want to put pain on other people; you put it on yourself. ”She said she used to cut herself“just to release the pain”.

Emily, 15, a friend of three of the girls treated in, June, said one was having family problems, one was“upset that day”and the third was“just upset with everything else going on”. She said they weren't really trying to kill themselves—they just needed concern. As Sobo noted, “What's going on in New Milford is not unique to New Milford. ”The same underlying culture of despair could be found in any town. But teen suicide, he added, can be a“contagion”. Right now New Milford has the bug-and has it bad.

What is the main subject of the passage？

A．Eight girls committed suicide in New Milford.

B．The village Green is not a charming place.

C．Teenager suicide.

D．Dr. Simon Sobo's achievements.

第一篇

A Debate on the English Language

A measure declaring English the national language is under intense debate in the United States.The US Senate passed two declarations last week.One calls English the nation's official language and the other says it is the "common and unifying（统一的）"tongue.But Americans found themselves divided on the issue.

Since people worldwide know that most Americans speak only English,many can't understand why the issue is so controversial（有争议的）.

"The discussion is related to fears of immigration issues,"says Dick Tucker,a social scientist at Pittsburgh's Carnegie Mellon University."It's related to a worry about the changing demography（人口统计）of the US.It's a worry about who will continue to have political and economic influence."

In fact,the notion of protecting the language has been kicked around almost since the nation's founding.John Adams lobbied（游说）in 1780 for the creation of a national academy to correct and improve the English language.But his proposal died,since lawmakers saw it as a royalist（保皇主义者）attempt to define personal behavior.

Since then,the country hasn't had a national language,but the idea of recognizing the special status of English lived on.

The emotions surrounding language resurface（再次浮现）not because people feel comfortable with English.It is more about the discomfort many Americans feel with the new languages,says Walt Wolfram,a professor at North Carolina State University.

"Language is never about language,"he says.

According to the 2000 US Census Bureau report,of 209 million Americans over 18 years old,172 million speak only English at home.About 37 million speak languages other than English.Among them,6.5 million speak poor English and 3.1 million don't speak English at all.

31.What are the two declarations concerned with？

A.The status of the English language.

B.The protection of new languages.

C.The rights to speak one's mother tongue.

D.The improvement of the English language.

New Attempts to Eradicate AIDS VirusA high-profile attempt to eradicate the AIDS virus in

New Attempts to Eradicate AIDS Virus

A high-profile attempt to eradicate the AIDS virus in a few patients continues to show promise.

But researchers won't know for a year or more whether it will work, scientist David Ho told journalists here Wednesday for the Fourth Conference in Viruses and Infections.

"This is a study that's in progress," says Ho, head of the Aaron Diamond AIDS Research Center, New York.

The study involves 20 people who started combinations of anti-HIV drugs very early in the course of the disease, within 90 days of their infections. They've been treated for up to 18 months. Four others have dropped out because of side effects or problems complying with the exacting drug system.

The drugs have knocked the AIDS virus down to undetectable levels in the blood of all remaining patients, s And, in the latest development6, scientists have now tested lymph nodes and semen from a few patients and found no virus reproducing there, Ho says. "Bear in mind that？ undetectable does not equal absent," Ho says.

Ho has calculated that the drugs should be able to wipe out remaining viruses -- at least from known reservoirs throughout the body -- in two to three years. But the only way to prove eradication would be to stop the drugs and see if the virus comes back8. On Wednesday, Ho said he wouldn't ask any patient to consider that step before 2years of treatment.

And he emphasized that he is not urging widespread adoption of such early, aggressive treatment outside of trials9. No one knows the long-term risks.

But other scientists are looking at similar experiments. A federally funded study will put 300 patients on triple-drug treatments and then see if some responding well after six months can continue to suppress the virus on just one or two drugs, says researcher Douglas Richman of the University of California, San Diego. Some patients in that study also may be offered the chance to stop therapy after 18 months or more, he says.

According to the passage, the attempt to eradicate the AIDS virus

A．continues to be hopeful.

B．will be successful in a year.

C．will be successful in future.

D．will stop being hopeful.

U. S. Life Expectancy Hite New High

Life expectancy rates in the United States are al an all—time high, with people born in

2005 projected to live for nearly 78 years, a new federal study finds.

The finding reflects a continuing trend of increasing life expectancy that began in l955, when the average American lived to be 69.6 years old. By l995, lire expectancy was 75.8 years and by 2006, it had risen to 77. 9 years, according to the report released Wednesday.

"This is good news," said report co-author Donna Hoyert, a health scientist at the national Center for Health Statistics. “It's even better news that it is a continuation of trends, so it is a long period of continuing improvement."

Despite the upward trend, the United States still has lower lire expectancy than some 40 other countries, according to the U. S. Census （人口普查） Bureau. The country with the longest lire expectancy is Andorra at 83.5 years, followed by Japan, Macau, San Marino and Singapore.

Much of the increase owes to declining death rates from the three leading causes of death in the country-heart disease, cancer and stroke.

In addition, in 2005, the U. S. death rate dropped to an all-time low of less than 800 deaths per l00, 000.

Dr. David Katz, director of the Prevention Research Center at Yale University School Medicine. Said, "News that lire expectancy is increasing is, of course, good. But the evidence we have suggests that there is more chronic disease than ever in the U. S."

Adding years to life is a good thing, Katz said. "But adding vital life to years is at least equally important. If we care about living well, and not just longer, we still have our work cut out for us." he said.

31 Since l 955, lire expectancy rates in the U. S. have

A moved up and down. B been declining.

C remained steady. D been on the rise.
