If you were on the street in Mexico today you might think you were in an operating room, surrounded by doctors. You could see many concerned people with masks (口罩) trying their best to stop the swine flu (豬流感). And the masks aren’t only being used in Mexico. A friend of mine traveling from New York City to Florida was given a mask and a pair of gloves just after he reached the airport. And another friend went to get a haircut only to be faced with a hairdresser wearing a mask!
But do the masks really work? Is covering your nose and mouth the key to stopping the swine flu? To find out the truth, ABC’s reporter Sharyn Alfonsi talked with germ (細菌) expert Dr. Elaine Larsen. It turns out that when you sneeze (打噴嚏) the air coming out of your mouth at a speed of one hundred miles per hour carries germs which can travel anywhere around you and make people around you infected (被感染).
However, whether you become infected actually depends on the weather. As Sharyn reported, when you sneeze, the germs leave your body in small drops of water coming out of your mouth. If the weather is wet, the wet air will make the small drops bigger and heavier and they drop down towards our feet. If this happens, we won’t become infected. But if the air is dry, those small drops can float higher up, making it possible for them to touch someone else’s nose, mouth or their mask.
Larsen says the masks can stop the germs well but after a few hours, they start to get wet, holding a lot of germs they come across and causing you to breathe them in. The masks do work, but the key to stopping the germs is changing your masks often.

Now Hear This
What do former American president Bill Clinton and rock musician Pete Townshend have in common.'? Both men have hearing damage from exposure to loud music, and both now wear hearing aids as a consequence. As a teenager, Clinton played saxophone in a band. Townshend, who has the more severe hearing loss, was a guitarist for a band called the Who. He is one of the first rock musicians to call the public's attention to the problem of hearing loss from exposure to loud music.
Temporary hearing loss can happen after only 15 minutes of listening to loud music. One early warning sign is when your ears begin to feel warm while you listen to music at a rock concert or through headphones. One later is that an unusual sound or a ringing is sometimes produced in your head after the concert.
"What happens is that the hair cells in the inner ear are damaged, but they're not dead," says physician and ear specialist Dr. Sam Levine. According to Dr. Levine, if you avoid further exposure to loud noise, it's possible to recondition the cells somewhat. However, he adds, "Eventually, over a long period of time, hair cells are permanently damaged." And this is no small problem.
What sound level is dangerous? According to Dr. Levine, regular exposure to noise above 85 decibels (分貝) is considered dangerous. The chart below offers a comparison of decibel levels to certain sounds. Here's another measurement you can use. If you're at a rock concert and the music is so loud that you have to shout to make yourself heard, you' re at risk for hearing loss. That's when wearing protective devices such as earplugs becomes critical.
The facts are pretty frightening. But are rock bands turning down the volume.'? Most aren't. "Rock music is supposed to be loud," says drummer Andrew Sather.  "I wouldn't have it any other way. And neither would the real fans of rock. "
Continued exposure to loud music and the failure to wear earplugs can lead to deafness, according to Dr. Levine. He states, "There's no cure for hearing loss. Your ears are trying to tell you something. That ringing is the scream of your hair cells dying. Each time that happens, more and more damage is done. "
Levels of Common Noises
Normal conversation                           50 — 65 dB
Food blender                                  88 dB
Jet plane flying above a person standing outside      103 dB
Rock band during a concert                      110 — 140 dB
小題1:From Paragraph 1, we can learn that                   .
A.loud music is a major cause of hearing loss
B.famous people tend to have hearing problems
C.teenagers should stay away from school bands
D.the problem of hearing damage is widely known
小題2:In Paragraph 3, the underlined word "recondition" means                .
A.not to be seenB.to fill with sound
C.to become larger in sizeD.to make good again
小題3:The purpose of the chart at the end of the article is to show                   .
A.a(chǎn) list of harmful sounds
B.the effect of rock concerts
C.the noise levels of familiar sounds
D.relationship between daily activities and hearing loss
小題4:Which of the following statements will Dr. Sam Levine probably agree?
A.When your ears feel warm, your hair cells are dead.
B.Drummer Andrew Sather gives good advice.
C.Many are taking the risk of losing hearing.
D.Doctors know how to cure hearing loss.

People who averaged fewer than seven hours of sleep per night in the weeks before being exposed to the cold virus were nearly three times as likely to get sick as those who averaged eight hours or more, a new study found.
Researchers used frequent telephone interviews to track the sleep habits of more than 150 men and women aged 21 to 55 over the last few weeks. Then they exposed the subjects to the virus, quarantined (檢疫隔離) them for five days and kept track of who got sick.
Besides sleeping more, sleeping better also seemed to help the body fight illness: Patients who fared better on a measure known as “sleep efficiency”—the percentage of time in bed that you’re actually sleeping—were also less likely to get sick.
The results held true even after researchers adjusted for elements such as body-mass index, age, sex, smoking and pre-existing antibodies (抗體) to the virus.
The researchers aren’t exactly sure why sleeping better makes you less likely to develop a cold. But they do try to give an answer: “Sleep disturbance influences the regulation of symptom mediators (調(diào)節(jié)因子) that are released in response to infection.” In plain English, maybe tossing and turning when you’re infected with the cold virus contributes to the symptoms that define a cold.
The researchers were based at Carnegie Mellon, the University of Pittsburgh and the University of Virginia, and the study was funded by the National Institutes of Health.
小題1: According to the passage, what does the underlined word “subjects” mean in paragraph 2?
A.a(chǎn)reas of knowledge in a school
B.people being studied in an experiment
C.research topics
D.a(chǎn)nimals being tested
小題2:It is shown in the passage that _______.
A.the researchers obtain information about the sleep habits by frequent interviews
B.the researchers do their research in the National Institutes of Health
C.people hope to avoid being infected with a cold by sleeping as much as possible
D.sleeping more and better helps regulate the symptom mediators
小題3:What’s the best title of the passage?
A.The Relationship Between Virus and Cold
B.How to Sleep Well
C.Good Sleep Helps Fight a Cold
D.The More the Sleep, the Better Your Body

Risk of death is 3.5 to 5 times greater for obese (肥胖的) smokers than it is for people who have never smoked and are at a normal weight, according to a study published in the November, 2006 issue of the American Journal of Preventive Medicine.
The study, which began with a self-administered questionnaire taken between 1983 and 1989, asked more than 80,000 radiologic technologists aged 22 to 92 questions about age, height, weight and smoking behavior.
BMI (body mass index) was calculated, with a BMI of 30 to 34.9 being considered obese, and 35 and over being very obese. Smoking behavior was analyzed by looking at a person's tobacco consumption level, number of years smoked, and current smoking status. Researchers then followed participants through December of 2002, noting the number of deaths that occurred.
The study involved researchers from the National Cancer Institute, the University of Minnesota and the American Registry of Radiolegic Technologists.
Key Findings:
20 percent of obese adults in the United States smoke.
Obese smokers face a greater risk of death from cancer and circulatory disease.
Current smoking is a greater risk factor for death by cancer than obesity is, generally speaking.
The higher a person's pack-years (number of packs smoked per day times the number of years smoked) are, the greater the risk of death.
Men and women of all ages faced an elevated risk of death due to circulatory disease as BMI increased. And for those who were both obese and currently smoking, risk of circulatory disease increased 6 to 11 times under the age of 65, as compared to their never-smoking, normal weight counterparts.
While it's not surprising that obesity coupled with smoking is a recipe for trouble, it is important to highlight this growing health concern in America today.
Taking Charge of Your Health
Making healthy choices can be difficult when we're constantly exposed to products that are dangerous to our health, but it's not impossible. With education and some motivation, we all have the ability to make lasting changes for the better. If you're an overweight smoker worried about gaining weight due to quitting, take heart. It's never too late to change your course and even reduce damage to some extent.

UGG boots have been a winter-weather fashion for several years now, combining function, comfort, warmth and even some style. What many UGG enthusiasts don’t know is that their boots are a breeding ground for bacteria and causes foot problems.
Doctors believe the boots, which are particularly popular among young teenage girls, are leading to a rise in the number of people suffering pains in their feet and knees.
Dr. Ian Drysdale, head of the British College of Osteopathic Medicine, believes because the foot does not get the proper support on the inside, it will lead to more ankle, knee, hip and back problems. “ These boots are not designed for outside wear. Just because something becomes a trend or fashionable doesn’t mean it’s good or right,” he said. “ The particular problem with this type of footwear is that it is unsupported. It is a slipper. You wouldn’t normally expect to be doing outdoor activities from something that’s indoor. If you decide to wear your pajamas outside all the time, someone will come up and say it’s not a good idea.” Dr. Drysdale explained that the feet issues become a particular problem among young teenage girls, whose bones are “plastic” and developing when they are growing. “ If that structure is developing in an inappropriate way,” he said, “then the ultimate structure will be deformed.
UGG Australia, who makes the designer version of the boots, told The Daily Mirror that their boots are “comfort” rather than “performance” footwear and consumers should be aware of “knockoffs(仿制品)” which lack reinforce heels in their boots.
小題1: Teenage girls prefer to wear UGG boots because of the following except__________.
A.designB.comfortC.qualityD.warmth
小題2:According to Dr.Ian Drysdale,____________.
A.there is a possibility that bacteria will multiply in UGG boots
B.wearing UGG boots will lead to more ankle and toe problems
C.it’s not a good idea to wear boots like UGG outside all the time.
D.teenage girls’ bones are plastic enough to wear UGG boots

A.shapedB.strengthenedC.reformedD.damaged

“In only six days I lost seven pounds of weight.”
“Two full inches in the first three days!”
These are the kinds of statements used in magazine,newspaper,radio and television ads,promising new shapes and new looks to those who buy the medicine or the device. The promoters of products say they can shape the legs,slim the face,smooth wrinkles,or in some other way to add to beauty or desirability.
Often such products are nothing more than money­making things for their promoters. The results they produce are questionable,and some are dangerous to health.
To understand how these products can be legally promoted to the public,it is necessary to understand something of the laws covering their regulation. If the product is a drug,F(xiàn)DA(Food and Drug Administration)can require proof under the Food,Drug,and Cosmetic Act that is safe and effective before it is put on the market. But if the product is a device,F(xiàn)DA has no authority to require the proof of safety or effectiveness. If a product already on the market is a danger to health,F(xiàn)DA can request the producer or distributor to remove it from the market voluntarily,or it can take legal action,including seizure (查封) of the product.
One notable case a few years ago involved an electrical device called the Relaxacisor,which had been sold for reducing the waistline. The Relaxacisor produced electrical shocks to the body through contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds that it was dangerous to health and life.
Obviously,most of the devices on the market have never been the subject of court proceedings (法律訴訟),and new devices appear continually. Before buying,it is up to the consumer to judge the safety or effectiveness of such items.
小題1:It can be inferred that the ads mentioned in the text are________.
A.objectiveB.costlyC.unreliableD.illegal
小題2:Which of the following is TRUE according to the text?
A.The court is in charge of removing dangerous products.
B.New products are more likely to be questionable. 
C.The production of a device must be approved by FDA.
D.The promoters usually just care about profits.
小題3:FDA can ask for the proof of safety and effectiveness of a product________.
A.if it is a drug
B.if it is a device
C.if its consumers make complaints
D.if its distributors challenge FDA's authority
小題4:The Relaxacisor is mentioned as________.
A.a(chǎn) product which was designed to produce electricity
B.a(chǎn) product whose distributor was involved in a legal case
C.a(chǎn) successful advertisement of a beauty product
D.a(chǎn)n example of a quality beauty product

Dieters' who eat meals high in protein might lose a bit more weight than those who get less protein and more carbohydrates (碳水化合物)一all other things being equal, a new analysis of past studies suggests. Researchers found that over an average of 12 weeks, people having a high一protein diet lost about 1.8 extra pounds, and more body fat, than those having a standard-protein diet.
Wycherley from the University of South" Australia in Adelaide, the lead author on the study says it’s possible that the body may spend more energy and bum more calories while dealing with protein, compared to carbohydrates. Another explanation for the link his team observed is that eating protein helps preserve muscle mass and muscle mass bums more calories, even when the body is resting, than other types of mass. He says people in the studies tend to get protein from a variety of animal and vegetable sources. Vegetable sources of protein include beans.
It is not obvious why a higher protein-to-carbohydrate ratio might help people lose more pounds——and one obesity researcher not involved in the new analysis questioned whether the trials were strong enough to make that conclusion. “The studies are generally far too short to tell effect,” Dr. James Levine from the Mayo Clinic in Scottsdale, Arizona, told Reuters Health in an e-mail. But given the limitations of the present evidence, Levine said, “It makes no real difference which of the weight-loss ways one chooses.”
小題1:According to Wycherley’s analysis, dieters should take in more ______.
A.fatB.carbohydratesC.proteinD.calories
小題2:What can we learn from the studies?
A.It bums more calories to deal with carbohydrates.
B.Protein helps keep muscle mass which bums calories.
C.Vegetables contain more protein than animals.
D.No more calories are burned while the body is resting.
小題3:What is Levine’s attitude towards the conclusion of the studies?
A.Doubtful.B.Supportive.C.Curious.D.Agreeable.

Ten years ago I used to be very fit. I rode a bike to work and I got a lot of exercise at weekends. I used to play tennis a lot and go for long walks. In those days I didn’t earn very much. I had a job in an office. It wasn’t a very good job but I had a lot of time to do the things I enjoyed doing.
Then, about eight years ago, I got a much better job. The pay was better, but the hours were a lot longer. I bought a car and drove to work every day. I began to take people out to lunch. And I began to put on weight, too. I stopped playing tennis and going for long walks at weekends because I just didn’t have any time for things like that any more.
There’s a lot of stress in my job. Perhaps that’s why I started drinking more than I used to. For example, I used to have only half a glass of whisky when I got home, but then I started filling my glass to the top, and instead of having one glass, I would have several. I started smoking a lot, too. I never used to smoke at all.
Two months ago I had a heart attack. At first I just couldn’t believe it. Luckily it wasn’t very serious. The doctor advised me to stop smoking and to eat less. He also advised me to work less and get more exercise. But I just haven’t any time! My job takes everything out of me!
Sometimes I wonder if I should get another job. Perhaps I could do something as I used to. But if I do that, I won’t earn as much. I have a family to support. I have to think of them, too. I just don’t know what I should do. What do you think?
小題1:Compared with ten years ago, what is worse for the author now?
A.His job.B.His pay.
