Although doctors lack the data to know what exactly is behind the rise in skin cancers among young people, they suggest several factors: more time in the sun, improper use of sunscreens and a rise in tanning salon(阳光浴沙龙) visits. Skin doctors believe that young people are generally spending more time in the sun than their parents did and are either not using enough sunscreen or failing to apply it properly. They also claimed that many Americans, including the young, are spending more vacation hours in sunny climates than in previous decades.
In a study published in 1997 in the American Academy of Dermatology, a research team led by Dr June Robinson at Northwestern University Medical School found that during the decade ending in 1996, the number of Americans who reported at least one severe sunburn rose from 30 percent to 39 percent.
Doctors feel really worried that ______.
A．their patients will soon get older
B．adults are diagnosed with skin cancer
C．there is an outbreak of deadly aches on the skins
D．many younger people suffer from skin cancer
听力原文： That's how Shown O'Neill looks back on the heart attack he experienced shortly after his 31st birthday.
"I thought I was in perfect health," Shown says. "I was never sick. I woke up feeling good every morning."
Then on that fateful day in April 2002, he received a giant eye opener. He was working in his yard in Hixson and started having pain in his chest and arms. "I wag pretty sure what it was, but I couldn't believe it could be happening to roe." The good news is that because Shawn recognized the symptoms and went immediately to Memorial Noah Park Hospital, he received the treatment he needed and the damage to his heart muscle was minimal.
"Advances in medicine make it possible for us to stop many heart attacks and keep people alive if they get to the hospital in time," says Dr: Kinsman Wright, medical director of Cardiac Services at Memorial. "We have technology to pinpoint blockage in the cardiac, arteries and several options to open the vessels. And lifestyle. changes and medications are helping people reduce their risk factors."
But Dr. Wright doesn't see any decrease in heart disease. "With people living longer, we're seeing different types of heart disease. We need to keep studying and fighting it on all fronts."
(30)
A．Yes. Because he is never sick.
B．Yes. Because he wakes up feeling good every morning
C．No. Because his heart muscle was severely, damaged.
D．No. Because he suffered a heart attack.

Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 through 45.
Teenagers and young adults in the US are increasingly being diagnosed with skin cancer, according to doctors who warn that the development could lead to an outbreak of deadly aches on the skin as these patients get older. Doctors are especially disturbed by the numbers of younger people they are treating, which suggests that messages about avoiding the sun still aren't getting through and that the tanned skin (晒黑的皮肤) that was made popular by French designer Coco Chanel in the 1920s remains a sought- after look today.

People are using cell phones in a Manhattan subway. Most Americans believe that there are unspoken rules about using mobile phone etiquette, according to an online poll.
It's impolite to shout down their cell phones which may frighten other passengers. Checking emails, sending text messages and making telephone calls while in the company of other passengers are definite breeches of mobile phone manners. Texting during a date is also strictly forbidden.
But the majority of American people questioned in the online poll said that they would not be offended if they received an electronic "thank you" , instead of a written note and seventy-five percent had no objections to anyone using laptops, net books or cell phones in the bathroom. " Etiquette is first and foremost a question of awareness, " said the author and etiquette expert AnnaPost. But she described the results of the Harris Interactive poll commissioned by Intel as " pretty surprising statistics".
Sixty-two percent of the 2, 625 adults who took part in the survey agreed that cell phones, laptops, net books and other electronic devices are part of daily life. Fifty-five percent also thought that the demands of business mean people must stay connected, even if it involves taking a laptop on a holiday or answering a cell phone during a meal.
Despite the need to be constantly connected and the general acceptance of the technology, people were more sensitive about technology abuses during holiday and religious activities. Nearly ninety percent of Americans think that cell phone use is unacceptable during a religious service and thirty percent admitted they would be offended if they received an online gift wish. But more than half revealed that they intended to send an electronic greeting card, instead of a traditional one.
" These are issues about common sense, " said Dr Genevieve Bell, an ethnographer and director of Intel's User Experience Group, adding that the social rules of when and how it is appropriate to use the technology are still being formed.
Which of the following sentences is right according to the passage？
A．75 percent of people in the online poll had no objections to anyone using laptops, net books and cell phones in the bathroom.
B．Nearly all of Americans think cell phone use is impolite during religious activities.
C．90 percent of people in the online poll admitted they would be unhappy if they were given an online gift wish.
D．30 percent of people in the online poll believe that people should get in touch with each other frequently because of the demand of business.
A study, known as CALERIE (Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy), was sponsored by America's National Institutes of Health. It took 48 men and women aged between 25 and 50 and assigned them randomly to either a control group or a calorie-restriction regime. Those in the second group were required to cut their calorie intake for six months to 75% of that needed to maintain their weight.
The CALERIE study is a landmark in the history of the field, because its subjects were either of normal weight or only slightly overweight. Previous projects have used individuals who were clinically obese(肥胖的), thus confusing the unquestionable benefits to health of reducing obesity with the possible advantages of calorie restriction to the otherwise healthy.
At a molecular level, CALERIE suggests these advantages are real. For example, those on restricted diets had showed drops in body temperature and blood-insulin(胰岛素) levels—both phenomena that have been seen in long-lived, calorie-restricted animals. Dr Rattan doubts whether calorie restriction will extend maximum human life expectancy. He argues that the concepts of ageing and longevity(长寿) must be separated. It may, indeed, be possible to reduce or eliminate particular age-related diseases, and that would increase average lifespan in the way that eliminating other diseases has done in the past. But this is not the same as slowing down aging itself, and thus increasing maximum lifespan. Longevity is a more complex trait than any individual disease, and, in his opinion, it will not be altered so easily.
Cynthia Kenyon, a researcher looking into anti-aging drugs, believes that some molecules are likely to be approved in the next five to ten years, for guarding against age-related diseases. People then will start taking them, and a huge natural experiment will get under way. If Dr Rattan is wrong, maximum lifespan as well as average lifespan will increase. If he is right, at least people will enjoy a healthier old age.
It can be inferred from the first paragraph that ______.
A．an effective calorie restriction involves taking little food while doing much exercise
B．calorie restriction is proved to be effective in preventing illness in some animals
C．some drugs are taken by people to live longer without suffering from starvation
D．before the 1930s,people did not believe in the positive effect in extending lifespan
The researchers also concluded that there were large numbers of deaths among the elderly from another virus, respiratory syncytial virus, known as R. S. V. As many as 78 percent of the 11,000 people who died from R. S. V. each year were 65 and older, the researchers concluded.
In an editorial accompanying the paper, Dr. David M. Morens of the National Institute of Allergy and Infectious Diseases, said that many people who were particularly vulnerable to influenza did not get flu vaccines, the only method of preventing the disease. Many mistakenly believe that the vaccine, which is made from a killed virus, can give them the flu. Over the last few years, Dr. Fukuda said, just 65 percent to 67 percent of people 65 and older were immunized. Even when they do get the vaccine, he added, it is less effective in the elderly than it is in younger people. And there is no vaccine to protect against R. S. V. Dr; Morens was not optimistic about the immediate future. The best hope, he said, is for improved flu vaccines and a vaccine for R. S.V. But for now, he said, doctors must do a better job of persuading older people to be vaccinated.
How many flu deaths a year in the 1990's？
A．20,000
B．26,000
C．30,000
D．36,000

Human creativeness is boundless. With the advance of science and technology, a complete new means of communication - Mobile Phone came to the world, which, being not fixed in one place like ordinary phones, greatly facilitates telephone communication. Although using mobile phone is convenient, it also has some negative factors. It tells us that we should pay more attention to the mobile phone etiquette. There is a research on American mobile phone etiquette.
People are using cell phones in a Manhattan subway. Most Americans believe that there are unspoken rules about using mobile phone etiquette, according to an online poll.
It's impolite to shout down their cell phones which may frighten other passengers. Checking emails, sending text messages and making telephone calls while in the company of other passengers are definite breeches of mobile phone manners. Texting during a date is also strictly forbidden.
But the majority of American people questioned in the online poll said that they would not be offended if they received an electronic "thank you" , instead of a written note and seventy-five percent had no objections to anyone using laptops, net books or cell phones in the bathroom. "Etiquette is first and foremost a question of awareness," said the author and etiquette expert Anna
Post. But she described the results of the Harris Interactive poll commissioned by Intel as " pretty
surprising statistics" .
Sixty-two percent of the 2 ,625 adults who took part in the survey agreed that cell phones, lap-tops, net books and other electronic devices are part of daily life. Fifty-five percent also thought that the demands of business mean people must stay connected, even if it involves taking a laptop on a holiday or answering a cell phone during a meal.
Despite the need to be constantly connected and the general acceptance of the technology, people were more sensitive about technology abuses during holiday and religious activities.
