There are many commonly held beliefs about eyeglasses and eyesight that are not proved facts. For example, some people believe that wearing glasses too soon weaken the eyes. But there is nothing to show that the structure (结构) of eyes is changed by wearing galsses at a young age. Wearing the wrong galsses, however, can prove harmful. Studies show that only children can develop loss of sihgt if they have the wrong glasses. We have all heard some of the common myths(荒诞的说法)about how eyesight get bad. Too little light makes the eyes work harder, so they do get tired and strained (过劳). Eyestrain also resulsts from reading a lot, reading in bed, and watching too much television. But, although eyestrain may cause some pain or headaches, it does not harm eyesight all the time. Another myth about eyes is that they can be replaced from one person to another . It is quite difficult to connect aneyeball to a new brain.And it is impossible to replace a whole eyeball to a new person. Only certain parts of the eye can be replaced now. But if we keep clearing up the myths and learning more about the eyes, some day it may be possible to replace a full eyeball.

Your body, which has close relations with the food you eat, is the most important thing you own, so it needs proper treatment and proper nourishment（营养）. The old saying “An apple a day keeps the doctor away. ” is not as silly as some people think. The body needs fruit and vegetables because they contain vitamin C. Many people take extra vitamins in pill form(丸剂), believing that these will make them healthy. But a good diet is made up of nourishing food and this gives all the vitamins you need. The body doesn’t need or use extra vitamins, so why waste money on them?

Coffee is one of the world's most widely-enjoyed drinks. Now, a new research suggests that if you drink enough coffee, it might help you avoid certain kinds of cancer.
Dr. Mia Hashibe of the University of Utah School of Medicine was interested in the connection between coffee drinking and certain cancers of the head and neck. Researchers have looked into this before, but without reaching any firm conclusions. She said, "So this finding from our new study was quite a surprise. We didn't really have any expectation of which direction it could go into."
To sort out the confusion, Hashibe and her assistants used statistical (统计学 ) techniques to, in effect, make one big study out of the earlier smaller studies. She explained,  "Thanks to the earlier studies, we have a lot more power than earlier studies that looked at this. And we included 4,000 cancer patients who have cancer of the mouth and throat. And then 9,000 controls, people who do not have cancer. '
Those studies--in Europe and the United States--found that people who drank a lot of coffee were less likely to develop cancers of the mouth and throat. "We saw a protective effect for drinking more than 4 cups of coffee per day," Hashibe said. "This was the 40 percent decrease in risk. We did not see the same effect for drinking three cups or less per day."
Mia Hashibe said there was a weak connection between cancer risk and drinking coffee without caffeine. And she and her assistants found no proof that drinking tea provided the same protection as drinking Coffee. Their research is published in the journal Cancer Epidemiology, Biomarkers & Prevention.
Hashibe says it is not clear how coffee might protect drinkers from certain cancers. "There are a few chemicals that are known to be antioxidants （抗氧化物）in coffee. So we are thinking perhaps they are playing some sort of protective role against several cancers."
小题1:This passage is probably taken from __
A．a literature bookB．a travel journal
C．an old directoryD．a medical magazine
小题2:Dr. Hashibe expected nothing of her research because __
A．it was impossible to get the desired resultB．the research was much surprising in fact
C．no conclusions had been reached beforeD．the research team lacked faith in success
小题3:Which of the following might have something to do with the protection against mouth cancer?
A．Coffee without chemicals.B．Coffee without caffeine.
C．Four cups of tea a day.D．Antioxidants in coffee.
小题4:What do we know about Dr. Mia Hashibe and her research?
A．She knew for sure how coffee may affect drinkers.
B．She included 4,000 people without cancer in study.
C．She found an effect for three cups of coffee a day.
D．She based her research on several earlier studies.
小题5:What would be the best title for the text?
A．Drinking Coffee May Protect Some CancersB．Drinking Coffee May Prevent Some Cancers
C．Drinking Coffee May Cure Some CaneersD．Drinking Coffee May Cause Some Cancers
Dr. Glenn Tisman, a cancer specialist, knew his young neighbor, Ray Bateman, had an unusual mind. But he had no idea at the time that 12 - year – old Ray had the ability to become his partner in cancer research.
Ray’s parents remembered that at age four, Ray surprised them by fixing a broken vacuum cleaner（吸尘器）. When he was ten, he speedily constructed the family color television from a kit. Later, he succeeded in assembling（组装） a complex stereo system after two experts had failed to do the job.
When Ray was ten, he convinced his parents to buy him a computer. In a short time, Ray was able to do amazing things with the computer. Ray shared his enthusiasm for computers with Dr. Tisman, who used a computer for his research. The two discussed computers and medicine frequently. Amazingly, Ray understood the biology and chemistry related to Dr. Tisman’s medical research without any previous instruction.
Ray then worked with Dr. Tisman after school. He helped conduct research with the equipment and kept it in working order. The purpose of the research was to test the effectiveness of mixing an old cancer drug with certain vitamins. Ray analyzed patient test results by computer, while Dr. Tisman handled all patient contact. Together, they came up with solid research that helped advance cancer treatment.
In 1988, 14 - year - old Ray went with Dr. Tisman to a meeting of the American Federation for Clinical Research（AFCR）, where Ray presented their initial research findings. Using terminology（术语） beyond the grasp of most kids his age, Ray told the scientists how the new drug mixture caused fewer and milder side effects for cancer patients.
A year later, Ray returned to the meeting to update the findings of his and Dr. Tisman’s research. By then, he had become well - known for his devotion to finding cures for sick patients. Stories about him appeared in hundred of newspapers around the world. He appeared on television newscasts and talk shows.
Ray continued to spend most free hours working with Dr. Tisman. The two began studying the effects of vitamins on babies inside the womb（子宫）. However, Ray’s main interest remained cancer treatment, and he continues his research today.

The rising costs of health care have become a problem for man y countries in the world. To deal with this problem, it is recommended that a big part of the state 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 bankruptif the patients had taken ways for early prevention. For example, keeping a balanced diet, such as not consuming too much animal fat and trying to have enough vegetables and fruits, 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 or 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 problems 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, paying more attention to 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.

Doctors’ moonlighting is becoming popular in hospitals around China. It has not only raised a lot of heated discussions in the media, but also caught the attention of the central government in Beijing.
On December 26, a spokesman of the Ministry of Health stressed that the ministry was firmly against doctors’ moonlighting, while strict regulations should be applied to doctors taking part-time jobs, the Xinhua News Agency reported.
Last year, the Ministry sent out a notice to a variety of health organizations to speed up the reform of their personnel （人事） system. According to the notice, medical organizations can hire medical experts as part-time doctors but such activities should take place under the hospital’s management and regulations（规定）.
As for moonlighting--meaning that the doctor provides medical service without the permission of the original hospital--such activity goes against China’s Practicing Doctor Law, Xinhua reported.
In China, doctors used to be controlled by hospitals and they could work for only one hospital. However, as China’s medical personnel system reform developed, it has been recognized that medical human resources, just like human resources in other areas, should be shared by the whole society. But on the other hand, doctors’ taking part-time jobs should follow the relative regulations applied in the medical field.
First of all, they should follow relative government laws and regulations. They should also follow the rules and regulations set by the medical organizations they work for. In addition, they should pay taxes for their income from the part-time jobs. What matters most is that they should first finish their regular jobs as required and be responsible for patients to ensure qualified and safe medical treatment.
小题1:
What is the greatest difference between moonlighting and taking part-time jobs?
A．Doctors can earn more money by moonlighting than by taking part-time jobs.
B．Doctors pay fewer taxes for the money made by moonlighting than by taking
part-time jobs.
C．Taking part-time jobs is permitted by hospitals while moonlighting is-against
the present regulations.
D．Doctor’s part-time jobs, instead of moonlighting, are encouraged by health organizations.
小题2:
From this passage we know that doctors are allowed to        nowadays.
A．only work for one hospitalB．work for more than one hospital
C．work any time when they are free D．be out of control of hospitals
小题3:

A．a notice sent out by the Ministry of Health
B．regulations made by health organizations
C．China’s Practicing Doctor Law
D．a magazine or a newspaper

Laughter Yoga (瑜伽) is a unique technique invented by Dr Kataria, a doctor from India, by which you can learn to “Laugh for No Reason”. You don’t even need a sense of humor, no funny jokes or comedy programs — just a willingness to laugh — and in the present climate everyone needs to laugh more.
Laughter Yoga is a combination of Laughter Exercises and Yogic Breathing, so that you increase the amount of oxygen in your body while being playful, resulting in you feeling healthier, energetic and alive. This actually changes the physical conditions of your body so that you start to feel happier.
Laughter Yoga is generally done in groups although it can be practiced alone. When you make eye contact with someone and you’re both willing to laugh, the laughter is increased. However, we do say that you can “Fake (假装) it, fake it till you make it” because the body doesn’t know the difference between fake and true laughter; as long as you’re willing to laugh you’ll experience the same health benefits.
Laughter Yoga started in a park in Mumbai in 1995 with just 5 participants, and now there’re over 6,000 laughter clubs in 60 different countries — showing the willingness of the world to laugh together.
In the UK, Julie was one of the first people to train as a Laughter Leader with Dr Kataria in June 2002. In 2006 she was awarded Laughter Ambassador for her selfless service to promote Laughter Yoga.
“Yoga has been part of my life for 30 years but 7 years ago my life changed when I discovered Laughter Yoga. I believe laughter and yoga are both good for your health,” says Julie.

A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increases the risk.
Researchers from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma (黑素瘤)．They said that they found faults in studies that had reported associations between sunscreen use and higher risk of melanoma.
Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence (发生率) faster than any other cancer in the United States.
But questions has been raised about sunscreen and whether it may has opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning.
The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer--- people with fair skin and freckles (雀斑), for example--- are more likely to use sunscreen．As a result, it may appear that sunscreen users get cancer more often.
The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.
小题1:People with fair skin and freckles         .
A．seldom use sunscreen
B．are more in danger of skin cancer
C．can be free from the harm of the sun
D．often expose themselves to the sun
小题2:We can learn from the passage that         .
A．sunscreen users get skin cancer more often
B．the volunteers have proved the effect of sunscreen
C．the new study was based on the experiences of volunteers
D．the number of skin cancer patients is increasing in America
小题3:Which of the following can be the best title for this passage?
A．Sunscreen to Prevent Skin Cancer
B．Sunscreen to Increase Skin Cancer
C．Skin Cancer Caused by Sunscreen
D．Skin Cancer Caused by Freckles
Enough sleep is important to health. The amount o f sleep needed depends on the age of the person and the conditions in which sleep takes place. The young may need more sleep than the old, but usually eight hours are enough for the health of grown-ups.   Some can do with less than this amount, but others may need more. Every person knows his own need. It is then a matter of good judgement to satisfy his need. Sleep should always be enough to make one bring back his strength and get ready for a day’s
work.
Fresh air is necessary to sound sleep. It is not without reason for some people to think that it is practicable to sleep in the open air. When one can keep himself warm, out-of-door sleeping probably gives the body its most complete relaxation(松弛). Ability to sleep is largely a habit . The conditions referred to only lead to sleep. Out-of-door exercises, a good habit of regular hours and the avoidance(避免) of late eating and worry, which are largely within the control of any person, are all helpful to sound sleep.
A bath at bedtime, neither hot nor cool but of body temperature, may be helpful to sleep. Sleep-producing drug(药）should never be taken except when suggested by a doctor.
小题1:How many hours are usually enough for the health of a pupil?
