    A healthy amount of sunshine may be the secret to staying young. British scientists have discovered.
    Vitamin D is produced naturally by the skin in response to(对…的反应) sunlight and may help to slow the ageing process and protect against heart disease, according to the study.
    Researchers from King’s College London studied 2,160 women aged between 18 and 79, looking at their telomeres--- a biological marker of ageing found in DNA. As people get older, their telomeres get shorter and they become more susceptible(易受伤害的) to certain illnesses.
    But the study found women with high levels of vitamin D had comparatively longer telomeres--- a sign of being biologically younger and healthier.
    The study suggests vitamin D may help to slow down the ageing process of DNA, and therefore the ageing process as a whole.
    Lead researcher Dr Brent Richards said, “These results are exciting because they show for the first time that people who have higher levels of vitamin D may age more slowly than people with lower levels of vitamin D.” This could help to explain how vitamin D has a protective effect on many ageing related diseases, such as heart disease and cancer.”
    Professor Tim Spector, a co-author of the report, added, “Although it might sound absurd
    (荒唐的), it’s possible that the same sunshine which may increase our risk of skin cancer may also have a healthy effect on the general ageing process.”
    Vitamin D made by the action of sunlight on the skin accounts for 90 percent of the body’s supply, but lower levels can also be got through food such as fish, eggs and breakfast cereals(粥).
    Other studies have suggested the vitamin plays a key role in protecting against cancer and heart disease.
    小题1: A certain amount of sunshine helps people stay young because _____.
    A．people feel happy and energetic in the sun
    B．sunshine protects people against heart disease
    C．vitamin D makes one’s skin look young and healthy
    D．vitamin D may help to slow the ageing process
    小题2:From Brent Richards, we know that _____.
    A．sunlight causes skin cancer to people with high level of vitamin D
    B．the study generally has a healthy effect on the general ageing process
    C．vitamin D can only be got from fish, eggs and breakfast cereals
    D．the higher levels of vitamin D people have, the more slowly people may age
    小题3:What can we infer from the passage?
    A. Telomeres are important signs of ageing of the DNA.
    B. Sunlight can be dangerous as it causes skin cancer.
    C. Sunlight does a great deal of good to our health.
    D. Vitamin D can also be gained from food.

    Eating a diet high in processed food(加工食品)increases the risk of depression，research suggests．What's more，peopie who ate plenty of vegetables，fruit and fish actually had a lower risk of depression，the University College London team found．
    Data on diet among 3，500 middle-aged civil servants(公务员)were compared with their emotional state five years later，a British journal reported．They split the participants into two types of diet--those who ate a diet largely based on whole food，which inc!udes lots of fruit， vegetables and fish，and those who ate a mainly processed food diet，such as sweetened desserts，fried food，processed meat，refined grains and high fat dairy products After accounting for factors such as gender，age，education，physical activity，smoking habits and chronic(慢性的) diseases，they found a significant difference in the future depression risk with the different diets．
    Those who ate the most wholefood had a 26％ lower risk of future depression than those who ate the least wholefood．By contrast，people with a diet high in processed food had a 58％ higher risk of depression than those who ate a diet low in processed foods．
    Study author Dr. Archana SinghManoux pointed out there was a chance the finding could be explained by fl lifestyle factor they had not accounted for．
    There was a paper showing a Mediterranean diet was associated with a lower risk of depression，but the problem with that is if you live in Britain，the likelihood(可能性)of you eating a Mediterranean diet is not very high．
    Dr．Andrew McCulloeh，chief executive of the Mental Health Foundation，said，this study adds to an existing body of solid research that shows the strong links between what we eat and our mental health．
    He added people's diets were becoming increasingly unhealthy．The UK population is consuming less nutritious，fresh produce and more saturated(含饱和脂肪酸的)fats and sugars．
    小题1:The text is mainly about         .
    A．the increasingly unhealthy diet of the UK population
    B．the link between processed food and depression
    C．the relationship between physical and mental health
    D．fl healthy diet largely based on wholefood

    A．They are of different ages from young to old．
    B．They have been eating fl less heal thy diet these years．
    C．Most of them prefer wholefood to processed food．
    D．Those who ate wholefood generally were happier in the long term．
    小题3:What can we learn from what Dr．Archana Singh Manoux said?
    A．It is difficult for most British people to have a Mediterranean diet．

    Do you love the holidays, but hate gaining weight? You are not alone. Holidays are times for  celebrating. Many people are worried about their weight. With proper planning, though, it is possible to keep normal weight during the holidays. The idea is to enjoy the holidays but not to eat too much. You don’t have to turn away from the foods that you enjoy.
    Here are some tips for preventing（阻止） weight gain and maintaining（维持） physical fitness:

    Begin with soup and fruit or vegetables. Fill up beforehand on water-based soup and raw fruit or vegetables. Or drink a large glass of water before you eat to help you to feel full.
    Stick to physical activity. Don’t let exercise take a break during the holidays. A 20-minute walk help to burn off excess calories.

    All people need to sleep. Sleep is a necessary process that promotes proper body functioning and can improve the quality of your life. Not only is the quantity of sleep important, but also the quality of sleep.
    Your bedroom should be shaped to your taste and to allow you to sleep in a peaceful environment. One of the biggest mistakes people make in their sleep is to use their bedroom for activities other than sleep. If your bedroom also functions as a command station for your life and work, the likelihood of your sleeping being poor is rather high. Bedrooms should be designed, decorated and used for mainly sleep. TVs, computers and other things should not be in your bedroom if at all possible.
    Establishing regular sleeping and waking times can help improve the quality of your sleep especially for those suffering from sleeplessness. Avoid hot food, caffeine, sugar and alcohol at least 4 to 6 hours before your sleep time. Develop a regular exercise program. Proper exercise and nutrition will help improve sleeping patterns. However, avoid exercising 2 hours before sleeping, since this may stimulate your body and make sleeping more difficult.
    Establish a pre-bedtime rule that will help focus you on sleep. You can try meditation（沉思）,reading or deep breathing and relaxation. Your bedtime rule should be yours. Do not worry about it fitting into a specific category. Do what is the best for you.
    Things such as room temperature, noise and light levels and even your bed mattress can have a lot of effect on the quality of sleep that you experience. Block out distracting noises and lights. You are in your bedroom to sleep and not be distracted by environmental interferences（干扰）.

    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

    I’m fat. I’m too skinny. I’d be happy if I were taller, shorter, had curly hair, straight hair, a smaller nose, bigger muscles, longer legs. Do any of these statements sound familiar? Do you often put yourself down? If so, you’re not alone. As a teen, you’re going through a ton of changes in your body. And as your body changes, so does your image (形象) of yourself. Lots of people have trouble getting used to it and this can affect their confidence.
    Some people think they need to change how they look or act to feel good about themselves. But actually all you need to do is change the way you see your body and how you think about yourself.
    The first thing to do is recognize that your body is your own, no matter what shape, size, or color it comes in. If you’re very worried about your weight or size, go to your doctor to check that things are OK. But it’s no one’s business but your own what your body is like—finally, you have to be happy with yourself.
    Next, find which aspects (方面) of your appearance you can change and which you can’t change and need to accept—like their height, for example, or their shoe size.
    If there are things about yourself that you want to change and can do this by making goals for yourself. For example, if you want to get fit, make a pan to exercise every day and eat nutritious foods.
    When you hear negative comments coming from within yourself, tell yourself to stop. Try building your confidence by listing three things in your day that really gave you pleasure. It can be anything like the way the sun felt on your face, the sound of your favorite band, or the way someone laughed at your jokes.
    小题1:From the first paragraph, we can infer that           .
    A．many teens can’t accept their body change easily
    B．most teens like to have a special body image
    C．teens prefer to change their body image quickly

    D．源Learn from some celebrities on how to change your body.

    A．make yourself fall downB．say negative things about yourself

    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.

    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:
    The passage is taken most probably from           .
    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
    小题4:
    According to the passage, we have got to know that         .
    A．all doctors around China prefer moonlighting to part-time jobs
    B．moonlighting has been permitted by China’s practicing Doctor Law
    C．taxes should be paid for the money doctors get from their part-time jobs
    D．strict management policies have been adopted to direct the moonlighting
