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.

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 this 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. And, in the latest development, 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 back. On Wednesday, Ho said he wouldn't ask any patient to consider that step before 2 years of treatment.

And he emphasized that he is not urging widespread adoption of such early, aggressive treatment outside of trials. 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
