Health officials issued a waring over common energy-saving l一ghtbulbs(燈泡) after research showed some types could potentially harm the skin and may even raise the risk of cancer.
A study by the Health Protection Agency (HPA) found that some eco-friendly lightbuulbs release levels of ultraviolet (UV) (紫外線) radiation that are above recognized safety limits. The agency urged people who work with lamps nearby to avoid spending more than one hour within a foot of the eco-friendly bulbs. The warning was directed at those using desk lamps for long periods, such as jewellery makers, and others who might have lights close to their faces, such as car mechanics.
John O’Hagan, a scientist at the HPA’s centre for radiation, chemical and environmental dangers, began tests on the ligthbulbs after patient groups raised concern about them. Among the groups were patients with a skin disease called lupus, which makes people highly sensitive to light.
The tests measured UV light from the lamps and found the highest levels of UV radiation, measured 2cm from the lightbulbs, were equivalent to being outside in direct sunlight in the summer. The most immediate risk from the lightbulbs is a reddening of the skin similar to sunburn, but there is also a small increased risk of skin cancer associated with this, again similar to that of sunburn.
The risk of health problems from the lightbulbs was not so high that people should remove them from their homes. People are advised to avoid using open lightbulbs for long close work until the problem is sorted out. It has confirmed that the government will not be reviewing its strategy on introducing energy efficient lightbulbs.
小題1:The underlined word “equivalent” in paragraph 4  most probably means ______.
A.equalB.vitalC.relevantD.harmful
小題2:In order not to be harmed by the UV radiation from some lightbulbs, people should ______.
A.stop using eco-friendly lightbulbs at home
B.a(chǎn)void using open lightbulbs for long close work
C.take care not to expose their skin to direct sunlight
D.urge the government to ban the use of lightbulbs
小題3:In the next part, the author would most probably further explain _____.
A.why people needn’t remove the lightbulbs from their homes
B.how researchers have planned to sort out the problem
C.how the government has responded to HPA’s discovery
D.how long people should work close to the open lightbulbs
小題4:We can learn from the passage that ____.
A.health officials issued a warning over common lightbulbs.
B.jewellery makers should avoid working with the eco-friendly bulbs for more than one hour
C.John O’Hagan did tests on the lightbulbs with some patients
D.people are advised to avoid using open lightbulbs for long close work

The findings come ___36___ a study of nearly 1,000 US people that looked at diet, calorie intake and body mass index (BMI) - a measure of obesity.___37___ is found that those who ate chocolate a few times a week were, on ___38___, slimmer than those ___39___ ate it occasionally. Even though chocolate is loaded with calories, it contains ingredients(材料)that may favour weight loss ___40___ than fat synthesis, scientists believe.___41___ boosting calorie intake, regular chocolate consumption was related to lower BMI in the study, ___42___ is published in Archives of Internal Medicine. The link remained even when other factors, like how ___43___ exercise individuals did, were taken into ___44___.And it appears it is how often you eat chocolate that is important, rather than how much of it you eat. The ___45___ found no link with quantity consumed.
___46___ to the researchers, there is only one chance in a hundred that their findings could be explained by chance alone. Lead author Dr Beatrice Golomb, from the University of California at San Diego, said: "Our findings appear to add to a body of information suggesting that the composition of calories, not just the number of them, matters for determining their ultimate impact on weight."This is not the first time scientists ___47___ that chocolate may be healthy for us. Other studies have claimed chocolate may be good for the heart. Consumption of certain types of chocolate has been linked to some favourable changes in blood pressure, insulin(胰島素)sensitivity and cholesterol(膽固醇)level. And chocolate, ___48___ dark chocolate, does contain antioxidants(抗氧化劑)which can help to mop up harmful free radicals - unstable chemicals that can damage our cells.
Dr Golomb and her team believe that antioxidant compounds, called catechins(兒茶素), can improve lean muscle mass and reduce weight  ___49___ studies in rodents would suggest this might be so. Mice ___50___ for 15 days with epicatechin (present in dark chocolate) had improved exercise performance and observable changes to their muscle composition.They say clinical trials are now needed in humans to see ___51___ this is the case.
But before you reach ___52___ a chocolate bar, there are still lots of unanswered questions. And in the absence of conclusive evidence, experts advise caution.While there's no harm in allowing yourself a treat like ___53___ now and again, eating too much might be harmful because it often ___54___ a lot of sugar and fat too.And if you are looking to change your diet, you are ___55___ to benefit most from eating more fresh fruits and vegetables.

For the past many centuries, people had been enjoying the benefits of green tea for the body. Many people would prefer drinking green tea than white tea and black tea, simply because of its distinct aroma(香味) not found in other types of tea. Nowadays, keeping the natural greenish color of tea leaves remained just like before. This is done by preparing the green tea just like the way it was prepared before—by washing the leaves right after pulling off them from the bush, then boiling them.
There have been many healthful claims saying that drinking green tea-based products help a lot in improving the general health of their body. For a long time, there has been many beliefs saying that green tea can help, cure beriberi disease(腳氣病), treat wounds, and even prevent tiredness. Now modern technology determines that there are even added healthful benefits that include reducing the possibility of having a heart disease and helping people to lose more weight easily.
Besides, studies have found out that green tea has Polyphenols(多酚類), a type of flaonoid(類黃酮) that greatly reduces the amount of time of cell maturation. The flavonoid found in green tea is called EGCg- a stronger matter than Vitamin C and E. It is believed to be 20 times stronger than these mentioned vitamins.
Having two cups of green tea daily is a good routine for your body. However, most doctors would suggest drinking at least 4 cups a day is the best. You can slowly increase the amount of drinking it to allow your body to get used to it. There is nothing to lose but everything to gain in drinking green tea.

Psychology(心理學(xué)) has a new application in the field of medicine. Many doctors, together with their patients, are looking for alternative methods of treatment of physical problems. In large hospitals, modern therapy(療法) seems to focus on the physical disease. Patients may feel they are treated like broken machines. Some doctors have recognized this as a problem. They are now using psychological therapy, in which the patient is working with the doctors against the disease with the help of medicine. The patient does not wait for the medicine and treatment to cure him or her, but instead the patient joins in the fight.
The doctor knows that a disease affects a patient's body physically. The body of the patient changes because of the disease. He is not only physically affected, but also has an emotional response to the disease. Because his mind is affected, his attitude and behavior change. The medical treatment might cure the patient's physical problems, but the patient's mind must fight the emotional ones. For example, the studies of one doctor, Carl Simonton, M. D., have shown that a typical cancer patient has predictable attitudes. She typically feels depressed, upset, and angry. Her constant depression makes her acts unfriendly toward her family, friends, doctors, and nurses. Such attitudes and behaviors prevent recovery. Therefore, a doctor's treatment must help the patient change that. Simonton's method emphasizes treatment of the “whole” patient.
The attitude of a cancer patient receiving radiation therapy, an X-ray treatment, can become more positive. The physician who is following Simonton's psychological treatment plan suggests that the patient imagine that he or she can see the tumor(腫瘤) in the body. In the mental picture, the patient "sees" a powerful beam of radiation like a million bullets of energy. The patient imagines the beam hitting the tumor cells and causing them to shrink. For another cancer patient, Dr. Simonton asks him to imagine the medicine going from the stomach into the bloodstream and to the cancer cells. The patient imagines that the medicine is like an army fighting the diseased cells and sees the cancer cells gradually dying and his blood carry away the dead cells. Both the medical therapy and the patient's positive attitude fight the disease.
Doctors are not certain why this mental therapy works. However, this use of psychology does help some patients because their attitudes about themselves change. They become more confident because they use the power within their own minds to help stop the disease.
Another application of using the mind to help cure disease is the use of suggestion therapy. At first, the doctor helps the patient to concentrate deeply. The patient thinks only about one thing. He becomes so unaware of other things around him that he is asleep, or rather in a trance(催眠狀態(tài)). Then the physician makes “a suggestion” to the patient about the medical problem. The patient's mind responds to the suggestion even after the patient is no longer in the trance. In this way, the patient uses his mind to help his body respond to treatment.
Doctors have learned that this use of psychology is helpful for both adults and children. For example, physicians have used suggestion to help adults deal with the strong pain of some disease. Furthermore, sometimes the adult patient worries about her illness so much that the anxiety keeps her from getting well. The right suggestions may help the patient to stop being anxious. Such treatment may help the patient with a chronic(慢性的)diseases. Asthma (哮喘) is an example of a chronic disorder. Asthma is a disease that causes the patient to have difficulty in breathing. The patient starts to cough and sometimes has to fight to get the air that he or she needs. Psychology can help relieve the symptoms of this disorder. After suggestion therapy, the asthma patient breathes more easily.
Physicians have learned that the psychological method is very useful in treating children. Children respond quickly to the treatment because they are fascinated by it. For example, Dr. Basil R. Collison has worked with 121 asthmatic children in Sydney, Australia, and had good results. Twenty-five of the children had Excellent results. They were able to breathe more easily, and they did not need medication. Another forty-three were also helped. The symptoms of the asthma occurred less frequently, and when they did, they were not as strong. Most of the children also felt better about themselves. Doctors have also used suggestion to change habits like nail-biting, thumb-sucking, and sleep-related problems.
Many professional medical groups have accepted the medical use of psychology and that psychology has important applications in medicine.
小題1:What does the passage mainly discuss?
A.How suggestion therapy benefits adults and children.
B.How modern therapy focuses on the disease.

A.The patient waits for the medicine and treatment to cure him.
B.The doctor uses medical treatment to cure the patient's problems.
C.The doctor, the medicine, and the patient work together to fight disease.

小題3:What can we learn from the studies of Carl Simonton, M. D.?
A. The medical treatment can cure the patient's mental disease.
B. The treatment of a patient by treating the body and the mind is necessary.
C. The mental treatment is more important than medical treatment.
D. Few patients have emotional response to the disease.
小題4:The use of psychological therapy is helpful to some patients in that            .

Chocolate is good for your heart, skin and brain. Usually, people think that chocolate is bad for their health. They describe chocolate as “something to die for” or say “death by chocolate”.Now they should bite their tongues! Evidence(證據(jù)) is showing that some kinds of chocolate are actually good for you in the following ways:
A happier heart
Scientists at Harvard University recently examined 136 studies on cocoa—the main ingredient in chocolate and found that it does seem to strengthen the heart.Studies have shown heart benefits from increased blood flow.These benefits are the result of cocoa’s chemicals, which seem to prevent both cell damage and inflammation(炎癥).
Better blood pressure
If yours is high, chocolate may help.Jeffrey Blumberg from Tufts University recently found that people with high blood pressure who ate 3.5 ounces of dark chocolate per day for two weeks saw their blood pressure drop quickly.
Muscle magic
Chocolate milk may help you recover after a hard workout(鍛煉).In a small study at Indiana University, people who drank chocolate milk between workouts did better on a tiredness test than those who had some sports drinks
Better for your skin.German researchers gave 24 women a half-cup of special cocoa every day.After three months, the women’s skin was moister(滑潤的)and smoother.The research shows that chocolate helps protect and increase blood flow to the skin, improving its appearance.
Brain gains

More than 10 years ago, it was difficult to buy a tasty pineapple. The fruits that made it to the UK were green on the outside and, more often than not, hard with an unpleasant taste within. Then in 1966, the Del Monte Gold pineapple produced in Hawaii first hit our shelves.
The new type of pineapple looked more yellowy-gold than green. It was slightly softer on the outside and had a lot of juice inside. But the most important thing about this new type of pineapple was that it was twice as sweet as the hit-and-miss pineapples we had known. In no time, the Del Monte Gold took the market by storm, rapidly becoming the world’s best-selling pineapple variety, and delivering natural levels of sweetness in the mouth, up until then only found in tinned pineapple.
In nutrition it was all good news too. This nice tasting pineapple contained four times more vitamin C than the old green variety. Nutritionists said that it was not only full of vitamins, but also good against some diseases. People were understandably eager to be able to buy this wonderful fruit. The new type of pineapple was selling fast, and the Del Monte Gold pineapple rapidly became a fixture in the shopping basket of the healthy eater.
Seeing the growing market for its winning pineapple, Del Monte tried to keep market to itself. But other fruit companies developed similar pineapples. Del Monte turned to law for help, but failed. Those companies argued successfully that Del Monte’s attempts to keep the golden pineapple for itself were just a way to knock them out of the market.
小題1:We learn from the text that the new type of pineapple is __________.

Why do parents deny their kids’ weight?
Experts in childhood nutrition aren’t surprised by an investigation this summer that shows 50%of parents who have overweight children don’t realize their children Weigh too much.Many parents deny their children’s weight because they don’t want to have to change their own eating and exercise habits,says Keith Ayoob, a doctor who works with overweight children and their families in New York City.
Parents frequently ask him whether their children have a thyroid(甲狀腺) problem, but that’s rarely the case.“1t’s usually a dietary(有關(guān)飲食的) and lifestyle issue.It’s very difficult for parents to deal with their own food issues,”Ayoob says.An estimated 25 million children in the USA are overweight, which puts them at risk of developing diabetes(糖尿病), high blood Pressure and other health problems.A Consumer Reports magazine investigation released on July 25,2009 of 3.048 parents who have children aged 5 to 17 found that 91% say childhood obesity (肥胖) is a problem in the USA.

New York: Staying positive through the cold season could be your best defence against getting ill, new study findings suggest.
In an experiment that exposed healthy volunteers to a cold or flu virus, researchers found that people with a generally sunny disposition were less likely to fall ill. The findings, published in the journal Psychosomatic Medicine, build on evidence that a “positive emotional style” can help protect us from the common cold and other illnesses.
Researchers believe the reasons may be both objective----as in happiness improving immune, function----and subjective----as in happy people being less troubled by a sore throat or funny nose. "People with a positive emotional style may have different immune responses to the virus," explained lead study author Dr Sheldon Cohen of Carnegie Mellon University in Pittsburgh. "And when they do get a cold, they may interpret their illness as being less severe."
Cohen and his colleagues had found in a previous study that happier people seemed less likely to catch a cold, but some questions remained as to whether the emotional trait itself had the effect.
For the new study, the researchers had 193 healthy adults complete standard measures of personality traits, self-perceived health and emotional "style." Those who tended to be happy, energetic and easy-going were judged as having a positive emotional style, while those who were often unhappy, tense and hostile had a negative style.
The researchers gave them nasal(鼻的) drops containing either a cold virus or a particular flu virus. Over the next six days, the volunteers reported on any aches, pains, sneezing or congestion they had, while the researchers collected objective data, like daily mucus production. Cohen and his colleagues found that based on objective measures of nasal woes, happy people were less likely to develop a cold.
小題1:Which is the best title for the passage?
A.Stay Away From Being Negative
B.Positive or Negative, It’s Up To You
C.An Effective Medicine For Being Fit
D.Warm People Likely To Keep Cold Away
小題2:According to Dr Cohen’s research, the reason why some people are unlikely to catch a cold is that ___________________.
A.their cheerful mood benefits the immune system
B.they have developed a certain gene against flu virus
C.they are less likely to have s sore throat and funny nose
D.they have got a stronger self-confidence in their health
小題3:The underlined word “disposition” (paragraph 2) probably means ________.

Americans this year will swallow 15,000 tons of aspirin, one of the safest and most effective drugs invented by man. The most popular medicine in the world today, it is an effective pain reliever. Its bad effects are relatively mild and it is cheap.
For millions of people suffering from arthritis(關(guān)節(jié)炎), it is the only thing that works. Aspirin, in short, is truly the 20th-century wonder drug. It is also the second largest suicide drug and is the leading cause of poisoning among children. It has side effects that, although relatively mild, are largely unrecognized among users.?
Although aspirin was first sold by a German company in 1899, it has been around much longer than that. Hippocrates, in ancient Greece, understood the medical value of the leaves and tree bark which today are known to contain salicylates(水楊酸堿), the chemical in aspirin. During the 19th century, there was a great deal of experimentation in Europe with this chemical, and it led to the introduction of aspirin. By 1915, aspirin tablets were available in the United States.?
A small quantity of aspirin (two five-grain tablets) relieves pain and inflammation(炎癥). It also reduces fever by interfering with some of the body’s reactions.
小題1:The passage is written to          .
A.suggests us using more aspirinB.reminds us of the side effects of aspirin
C.gives us a whole view of aspirinD.discusses the good effects of aspirin
小題2:According to the author, aspirin         .
A.is very safeB.first appeared in 1899
C.can be harmful to childrenD.can hardly be dangerous
