2 . Peter Skyllberg, a Swedish man, was trapped in his car for two months, with temperatures reaching -30^oC, with no food or water, and yet he survived. The best explanation was that his vehicle created an “igloo (snow house) effect” and protected him from the extremely low temperatures and that his body would hibernate(冬眠) during this time.

Can humans get into a low-energy consumption state like a bear by reserving energy, and reducing body temperature? Chinese scientists are looking for the key to regulating body temperature.

Scientists have found the hypothalamus (下丘脑), an area in the central lower part of the brain, is responsible for regulating body temperature. Wang Hong, a brain scientist at the Shenzhen Institutes of Advanced Technology of the Chinese Academy of Sciences, led her team to mark the neurons (神经元) responsible for regulating body temperature in mice by means of a cutting-edge genetic biology technique. In the experiments, they injected (注射) drug into mice to make the body temperatures of the mice drop rom 37C to 27 in two hours. The team found the change in body temperature caused no harm to the health of the mice. “We don’t know if we can develop a drug that can control human body temperature. We still need a lot of study.” Wang said.

Chinese scientists are not alone in such research. Body-cooling techniques are being used in pioneering hospitals around the world. Dutch doctors are now using low temperatures for patients who have suffered brain injuries in accidents, According to doctors working in Florence, it may even help to save the brains of babies who are born suffering from severe epileptic fits (癫痫病发作).

3 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Increasingly, Americans are becoming their own doctors by going to diagnose their symptoms, order home health tests or medical devices, or even self-treat their illnesses with drugs from Internet pharmacies(药店).Some avoid doctors because of the high cost of medical care, especially    1     they lack health insurance. Or they may stay away because they find it    2    (embarrass) to discuss their weight, smoking, alcohol consumption or couch potato habits. Patients may also fear what they might learn about their health, or they distrust physicians because of negative     3     (experience) in the past. But    4    (play) doctor can also be a deadly game.

Every day, more than six million Americans turn to the Internet    5    medical answers--- and most of them aren’t nearly sceptical enough of what they find. A 2002 survey by the Pew Internet &American Life Project found that 72 percent of those    6    (survey) believe all or most of what they read on health websites. They shouldn’t look up “headache” and the chances of finding     7    (rely) and complete information, free from a motivation for commercial gain,    8     (be) only one in ten, reports an April 2005 Brown Medical School study. Of the 169 websites the researchers rated, only 16 scored as “high quality”. Recent studies found faulty facts about all sorts of other disorders, causing one research team to warn that a large amount of incomplete, inaccurate and even dangerous    9     (inform) exists on the Internet.

The problem is most people don’t know the safe way to surf the Web. “They use a search engine like Google, get 18 trillion choices and start clicking. But that’s risky, because almost anybody can put up a site that looks authoritative ( 权威的)，so it’s hard to know if what you’re reading is     10    (reason) or not,” says Dr.Sarah Bass from the National Cancer Institute.

4 . In a room at Texas Children Cancer Center in Houston, eight-year-old Simran Jatar lay in bed with a drip (点滴) above her to fight her bone cancer. Over her bald (秃的) head, she wore a pink hat that matched her clothes. But the third grader’s cheery dressing didn’t mask her pain and weary eyes.
Then a visitor showed up. “Do you want to write a song?” asked Anita Kruse, 49, rolling a cart equipped with an electronic keyboard, a microphone and speakers. Simran stared. “Have you ever written a poem?” Anita Kruse continued. “Well, yes,” Simran said.
Within minutes, Simran was reading her poem into the microphone. “Some bird soaring through the sky,” she said softly. “Imagination in its head…” Anita Kruse added piano music, a few warbling (鸣, 唱) birds, and finally the girl’s voice. Thirty minutes later, she presented Simran with a CD of her first recorded song.
That was the beginning of Anita Kruse’s project, Purple Songs Can Fly, one that has helped more than 125 young patients write and record songs. As a composer and pianist who had performed at the hospital, Kruse said that the idea of how she could help “came in one flash”.
The effect on the kids has been great. One teenage girl, curling (蜷缩) in pain in her wheelchair, stood unaided to dance to a hip-hop song she had written. A 12-year-old boy with Hodgkin’s disease who rarely spoke surprised his doctors with a song he called I Can Make It.
“My time with the kids is heartbreaking because of the severity of their illnesses,” says Anita Kruse. “But they also make you happy, when the children are smiling, excited to share their CD with their families.”
Simran is now an active sixth grader and cancer-free. From time to time, she and her mother listen to her song, Always Remembering, and they always remember the “really sweet and nice and loving” lady who gave them a shining moment in the dark hour.
