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 (猪流感). 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 (细菌) expert Dr. Elaine Larsen. It turns out that when you sneeze (打喷嚏) 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.

A recent study suggests that teens’ relationship with parents, friends and teachers may have a lot to do with why they don’t get a good night’s sleep.
David Maume, a sociologist and sleep researcher, analyzed federal health data, which interviewed 974 teenagers when they were 12, and then again at 15. He found that family dynamics (动态) have much to do with how well kids sleep. Teens, who had warm relations with their parents and felt like they could talk to them or their parents were supportive of them, tended to sleep better. However, families that were going through a divorce or a remarriage tended to affect teens’ sleep.
And problems at school also affected teens’ sleep. Feeling safe at school and having good relations with teachers tended to promote better sleep. As did good relationships with friends. Kids who took part in sports or other positive social activities or shared similar academic goals with their friends were also more likely to get a good night’s sleep.
These add up to what makes lots of sense: a general feeling of well-being helps teens sleep. If we’re happy and contented, we’re much more likely to sleep better than if we’re sad and anxious.
Now, of course, teens can hardly resist being drawn to their computers and social networking. Maume also found that when parents were strict not only about bedtime, but also about limiting technology, kids slept better. It’s a finding that seems obvious, but parents really do matter when it comes to health habits of their teenagers.
Clearly, teenagers aren’t getting 9 to 10 hours a night, which puts them at risk for all the consequences of lack of sleep, including poor academic performance, colds and stress.
【小题1】What is the passage mainly about?

A.Teens’ sleep is linked to their relationship with people around them.
B.Lack of adequate sleep puts teens at risk of many bad consequences.
C.Modern technology has something to do with teens’ sleep problems.
D.It is necessary for teens to join in sports and positive social activities.
【小题2】According to Maume’s analysis, who will probably have a poor night’s sleep?
A.Teens who feel like talking with their parents.
B.Teens who have friends sharing their dreams.
C.Teens who feel contented about themselves.
D.Teens who lack a sense of security at school.
【小题3】 Para 5 functions as              .
A.a comparison B.an introduction C.a conclusion D.an addition
【小题4】 Parents are supposed to               when their kids are growing up.
A.continue their broken marriage
B.allow children to decide when to sleep
C.limit teens’ using new technology
D.force teens to have 10 hours’ sleep daily

Putting in water fountains(饮水器) at schools, and teaching children about the health benefits of water, could reduce their risk of getting extra pounds, reports a new study that is published in the latest issue of the journal pediatrics.
The findings are based on a survey in 32 elementary schools of two German cities, Dortmund and Essen. The researchers, led by Rebecca Muckelbauer, a nutrionist at the Research Institute of Child Nutrition Dortmund, weighed about 3,000 children, and asked them about their beverage(饮料) consumption.
At the beginning of the school year, the experts had water fountains added to 17 of the schools. The scientists also worked with teachers to carry out educational programs that promote the benefits of drinking water. In contrast to schools in the United States, there are very few schools in Germany that have water fountains.
At the beginning of the study, there were no big differences in the number of overweight children in different groups. But by the end of the school year, children in the schools with water fountains were 31 percent less likely to gain extra pounds, compared to kids who went to other schools, where water drinking was not encouraged.[来源:学
Children in the schools with fountains, increased their water consumption from about 3 up to 4 glasses a day, while those in the other schools continued to drink an average of 3 glasses. Over the research, the number of overweight kids upped from 384 to 385 out of 1,641 at the schools with water fountains. In comparison, the number of overweight kids at the other schools increased from 339 to 364 out of 1,309, Dr. Muckelbauer said.
The experts cannot make any final conclusions and explain why the students who were encouraged to drink water were less likely to gain extra weight. Dr. Muckelbauer noted that according to a few other studies, drinking of water increases the rate at which calories are burned, while some other research suggested that water may temporarily decrease appetite.
【小题1】According to the text, the journal Pediatrics__________.

A.may cover the subject of the health of children
B.mainly deals with the water drinking problem
C.is mainly about the mental health of kids
D.must be a journal entitled(授权) by a school

C.It surveyed children in the countryside.
D.It lasted for a whole school year.
【小题3】The fifth paragraph is mainly about __________.
A.the technique used in the surveyB.the benefits of the survey
C.the process of the surveyD.the result of the survey
【小题4】What can be learned from the last paragraph?

The rising costs of health care have become a problem for many countries in the world. To deal with this problem, it is recommended that a big part of the government’s health budget be used for health education and disease prevention instead of treatment. Actually, many kinds of diseases are preventable in many ways and preventing a disease is usually much cheaper than treating it. For example, people could avoid catching a cold if they dressed warmly when the weather starts getting cold. But many people get sick because they fail to do so, and have to spend money seeing a doctor.
Daily habits like eating more healthy food would have kept millions of families from becoming bankrupt if the patients had taken measures for early prevention. For instance, keeping a balanced diet, such as not consuming too much animal fat and insuring a steady intake of vegetables and frits, seems to be quite important.
One very effective and costless way of prevention is regular exercise, which is necessary for a healthy mind and body. Regular exercise, such as running, walking, and playing sports is a good way to make people feel better and reduce stress.
In addition, health education plays a key role in improving people’s health. By giving people more information about health, countries could help people understand the importance of disease prevention and ways to achieve it. For example, knowing one’s family medical history is an effective way to help keep healthy. Information about health problem among close relatives will make them aware of what they should do to prevent certain diseases through lifestyle changes, Which will work before it is too late. 
However, stressing disease prevention does not mean medical treatment is unimportant. After all, prevention and treatment are just two different means toward the same effect. In conclusion, we could save money on health care and treat patients more successfully if our country spends more money on health prevention and education.
【小题1】What’s the best title of the passage?

A.Prevention or Education? B.Prevention or Treatment?
C.Health or Illness? D.Exercise or Illness?
【小题2】Which of the following can replace the underlined word “bankrupt”?
A.Unable to be cured B.Unable to pay one’s debts
C.Stronger than ever before D.More successful than ever before
【小题3】 We learn form the passage that _______
A.dressing warmly can prevent disease
B.a balanced diet is cheaper than regular exercise
C.the more health education, the better
D.the government’s health budget should be increased

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.www.zxxk.com
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.

When I was small and my grandmother died, I couldn’t understand why I had no tears. But that night when my dad tried to cheer (使…快活) me up, my laugh turned into crying.
So it came as no surprise to learn that researchers believe crying and laughing come from the same part of the brain. Just as laughing has many health advantages, scientists are discovering that so does crying.
Whatever it takes for us to reduce pressure is important to our emotional (情感的) health, and crying seems to work well. One study found that 85 percent of women and 73 percent of men report feeling better after crying.
Besides, tears attract help from other people. Researchers agree that when we cry, people around us become kinder and more friendly and they are more ready to offer support and comfort. Tears also enable us to understand our emotions better; sometimes we don't even know we're very sad until we cry. We learn about our emotions through crying, and then we can deal with them.
Just as crying can be healthy, not crying — holding back tears of anger, pain or suffering — can be bad for physical health. Studies have shown that too much control of emotions can lead to high blood pressure, heart problems and some other illnesses. If you have a health problem, doctors will certainly not ask you to cry. But when you feel like crying, don't fight it. It's a natural — and healthy — emotional response.
【小题1】Why didn't the author cry when her grandmother died?

A.Because her father did not want her to feel too sad.
B.Because she did not love her grandmother.
C.Because she was too shy to cry at that time.
D.The author doesn’t give the explanation.
【小题2】 It can be inferred (推断) from the text that ______.
A.there are two ways to keep healthy
B.laughing does more good to health than crying
C.crying and laughing play the same roles
D.emotional health has a close relationship to physical health
【小题3】 According to the author, which of the following statements is true?
A.Crying is the best way to get help from others.
B.Holding back tears may cause some health problems.
C.We will know our deep feelings if we cry.
D.We must cry if we want to reduce pressure.
【小题4】What might be the best title for the text?
A.Power of TearsB.How to Keep Healthy
C.Why We CryD.A New Scientific Discovery
【小题5】 What might the underlined word “fight” in the last paragraph mean?

科目:高中英语 来源: 题型:单选题

Shopping for clothes is not the same experience for a man as it is for a woman. A man goes shopping because he needs something. His purpose is settled and decided in advance. He knows what he wants, and his objective is to find it and buy it; the price is a secondary consideration. All men simply walk into a shop and ask the assistant for what they want. If the shop has it in stock(有现货的), the salesman promptly produces it, and the business of trying it on follows at once. All being well, the deal can be and often is completed in less than five minutes, with hardly any chat and to everyone's satisfaction.
For a man, slight problems may begin when the shop does not have what he wants, or does not have exactly what he wants. In that case the salesman, as the name implies, tries to sell the customer something else, he offers the nearest to the article required. No good salesman brings out such a substitute impolitely; he does so with skill: “I know this jacket is not the style you want, sir, but would you like to try it for size? It happens to be the color you mentioned.” Few men have patience with this treatment, and the usual response is: “This is the right color and may be the right size, but I should be wasting my time and yours by trying it on.”
Now how does a woman go about buying clothes? In almost every respect she does so in the opposite way. Her shopping is not often based on need. She has never fully made up her mind what she wants, and she is only “having a look round”. She is always open to persuasion; indeed she sets great store by what the saleswoman tells her, even by what companions tell her. She will try on any number of things. Uppermost in her mind is the thought of finding something that everyone thinks suits her. Contrary to a lot of jokes, most women have an excellent sense of value when they buy clothes. They are always on the lookout for the unexpected bargain. Faced with a roomful of dresses, a woman may easily spend an hour going from one rail to another, to and fro, often retracing her steps, before selecting the dresses she wants to try on. It is a laborious process, but apparently an enjoyable one. Most dress shops provide chairs for the waiting husbands.
【小题1】The underlined sentence “the price is a secondary consideration” in the first paragraph means when a man is shopping ______.

A.he buys good quality things, so long as they are not too dear
B.he buys whatever he likes without considering its value
C.he does not mind how much he has to pay for the right things
D.he often buys things without giving the matter proper thought.
【小题2】What does a man do when he can not get exactly what he wants?
A.He buys a similar thing because of the color he wants.
B.He usually does not buy anything.
C.At least two of his requirements must be met before he buys.
D.So long as the style is right, he buys the thing.
【小题3】What is the most obvious difference between men and women shoppers?
A.Men do not try clothes on in a shop while women do.
B.Women bargain for their clothes, but men do not.
C.The time they take over buying clothes.
D.Men go shopping based on need, but women never.
