“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，FDA(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，FDA has no authority to require premarketing proof of safety or effectiveness. If a product already on the market is a danger to health，FDA 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(法律诉讼)，and new devices appear continually. Before buying，it is up to the consumer to judge the safety or effectiveness of such items.

In a room at Texas Children Cancer Center in Houston, eight-year-old Simran Jatar lay in bed with a drip (点滴) above her to fight her bone cancer. Over her bald (秃的) head, she wore a pink hat that matched her clothes. But the third grader’s cheery dressing didn’t mask her pain and weary eyes.
Then a visitor showed up. “Do you want to write a song?” asked Anita Kruse, 49, rolling a cart equipped with an electronic keyboard, a microphone and speakers. Simran stared. “Have you ever written a poem?” Anita Kruse continued. “Well, yes,” Simran said.
Within minutes, Simran was reading her poem into the microphone. “Some bird soaring through the sky,” she said softly. “Imagination in its head…” Anita Kruse added piano music, a few warbling (鸣, 唱) birds, and finally the girl’s voice. Thirty minutes later, she presented Simran with a CD of her first recorded song.
That was the beginning of Anita Kruse’s project, Purple Songs Can Fly, one that has helped more than 125 young patients write and record songs. As a composer and pianist who had performed at the hospital, Kruse said that the idea of how she could help “came in one flash”.
The effect on the kids has been great. One teenage girl, curling (蜷缩) in pain in her wheelchair, stood unaided to dance to a hip-hop song she had written. A 12-year-old boy with Hodgkin’s disease who rarely spoke surprised his doctors with a song he called I Can Make It.
“My time with the kids is heartbreaking because of the severity of their illnesses,” says Anita Kruse. “But they also make you happy, when the children are smiling, excited to share their CD with their families.”
Simran is now an active sixth grader and cancer-free. From time to time, she and her mother listen to her song, Always Remembering, and they always remember the “really sweet and nice and loving” lady who gave them a shining moment in the dark hour.

A small piece of fish each day may keep the heart doctor away. That’s the finding of a study of Dutch men in which deaths from heart disease were more than 50 percent lower among those who consumed（消费） at least an ounce of salt water fish per day compared to those who never ate fish.
The Dutch research is one of three human studies that give strong scientific support to the long held belief that eating fish can provide health benefits, particularly to the heart.
Heart disease is the number-one killer in the United States, with more than 550,000deaths occurring from heart attacks each year. But previous research has shown that the level of heart disease is lower in cultures that consume more fish than Americans do. There are fewer heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption averages more than 3 ounces.
For 20 years, the Dutch study followed 852 middle-aged men, 20 percent of whom ate no fish.
At the start of the study, average fish consumption was about two-thirds of an ounce each day, with more men eating lean fish than fatty fish.
During the next two decades, 78of the men died from heart disease , The fewest deaths were among the group who regularly ate fish, even at levels far lower than those of the Japanese of Eskimos, This relationship was true regardless of other factors such as age, high blood pressure, or blood cholesterol(胆固醇)levels.
【小题1】Which of the following is NOT true according to the passage?

A．The Dutch research has proved that eating fish can help to prevent heart disease.

B．People who regularly eat fish never suffer from heart disease.

C．Heart disease causes more deaths in America than any other disease.

D．There is a low level of heart disease in such countries as Japan and Greenland.

【小题2】The passage is mainly about______.

A．the changes in people’s diet

B．the daily fish consumption of people in different cultures.

C．the high death rate of disease in some countries.

D．the effect of fish eating on people’s health

【小题3】We can infer from the passage that there are fewer heart disease deaths____.

A．in Dutch

B．in America

C．in countries with high consumption of fish

D．in countries with good production of fish

【小题4】The phrase“this relationship (paragraph 6) refers to the connection between ____ and the level of heart disease.”

A．the amount of fish eaten

B．regular fish-eating

C．the kind of fish eaten

D．people of different areas

How to Be a Winner
Sir Steven Redgrave
Winner of 5 Olympic Gold Medals
“In 1997 I was found to have developed diabetes (糖尿病) . Believing my career (职业生涯)was over, I felt extremely low. Then one of the specialists said there was no reason why I should stop training and competing. That was it----the encouragement I needed. I could still be a winner if I believed in myself. I am not saying that it isn’t difficult sometimes. But I wanted to prove to myself that I wasn’t finished yet. Nothing is to stand in my way.”
Karen Pickering
Swimming World Champion
“I swim 4 hours a day, 6 days a week. I manage that sort of workload by putting it on top of my diary. This is the key to success—you can’t follow a career in any field without being well-organized. List what you believe you can achieve. “Trust yourself, write down your goals for the day, however small they are, and you’ll be a step closer to achieving them.”
Kirsten Best
Poet ＆ Writer
“When things are getting hard, a voice inside my head tells me that I can’t achieve something. Then, there are other distractions, such as family or hobbies. The key is to concentrate. When I feel tense, it helps a lot to repeat words such as ‘calm’, ‘peace’ or ‘focus’, either out loud or silently in my mind. It makes me feel more in control and increases my confidence. This is a habit that can become second nature quite easily and is a powerful psychological (心理的) tool.”

Not all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive these experiences.
Now American researchers think they are close to developing a pill, which help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce, or possibly erase the effect of painful memories.
In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far, the research has suggested that only the emotional effects of memories may be reduced, not that the memories are erased.
The research has caused a great deal of argument. Some think it is a bad idea, while others support it. Supporters say it could lead to pills that prevent or treat soldiers’ troubling memories after wars.
They say that there are many people who suffer from terrible memories. “Some memories can ruin people’s lives. They come back to you when you don’t want to have them in a daydream or nightmare. They usually come with very painful emotions,” said Roger Pitman, a professor of psychiatry(精神病学)at Harvard Medical School. “This could relieve（减轻）a lot of that suffering.”
But those who are against the research say that changing memories is very dangerous because memories give us our identity. They also help us avoid the mistakes in the past. “All of us can think of bad events in our lives that were horrible at the time but make us who we are. I am not sure we’d want to wipe those memories out.” said Rebecca Dresser, a medical ethicist.
【小题1】What’s the main idea of this passage?

A．People often suffer from bad memories.

B．American researchers are trying to develop a pill.

C．Forget bad memories , and be happy.

D．The research has caused a heated argument.

【小题2】The underlined word “it” in Paragraph 4 refers to “_____”.

A．the new drug

D．the chemical in the drug

【小题3】Which of the following is NOT the opinion of the opponents(反对者)?

A．Our memories give us our identity.

B．The memories help human avoid mistakes of the past.

C．The drug should be used in only very serious cases.

D．People may not be sure whether they want to wipe the memories out.

Children of America are getting fatter every time. 13% of the children at the age of 6 to 11 are overweight(too fat).
When we look at children's lives today in the USA, we can see the root(origin)of the problem--sports and foods. Young children like sports but they don't have enough around the start of high school. That's especially true for girls. Meanwhile, to make matters worse, schools are becoming much more interested in sports teams. So children are not able to get enough exercise just when they need it the most. There is also the food problem. Children get most of their calories(热量) at restaurants or parties or somewhere else away from home. They often drink too many Cokes. Parents have a lot of fears about telling a child he needs to lose weight-- they are afraid it will push a child into an eating disorder. Some parents fear that pushing children to lose weight means their children will think they're not good enough, or not loved because of their weight. Parents need to come to terms with the fact that the family is very important to the children. The most useful program for children is called "family weight control". This is good news. Mom and Dad, even if they don't have weight problems, have to go through the same program as their children and learn how to get some exercise and how to eat healthily.

Medical drugs sometimes cause more damage than they cure. One solution to this problem is to put the drugs inside a capsule, protecting them from the body—and the body from them—until they can be released at just the right spot. There are lots of ways to trigger(引发) this release, including changing temperature, acidity, and so on. But triggers can come with their own risks—burns, for example. Now, researchers in California have designed what could be a harmless trigger to date: shining near-infrared light (NIR,近红外线) on the drug in the capsule.
The idea of using light to liberate the drug in the capsule isn't new. Researchers around the globe have developed polymers (聚合物) and other materials that begin to break down when they absorb either ultraviolet (UV,紫外线) or visible light. But tissues also readily absorb UV and visible light, which means the drug release can be triggered only near the skin, where the light can reach the capsule. NIR light largely passes through tissues, so researchers have tried to use it as a trigger. But few compounds(化合物) absorb NIR well and go through chemical changes.
That changed last year when Adah Almutairi, a chemist at the University of California, San Diego, reported that she and her colleagues had designed a polymer that breaks down when it absorbs NIR light. Their polymer used a commercially available NIR-absorbing group called o-nitrobenzyl (ONB). When they catch the light, ONB groups fall off the polymer, leading to its breakdown. But ONB is only a so-so NIR absorber, and it could be poisonous to cells when it separates from the polymer.
So Almutairi and her colleagues reported creating a new material for capsules that's even better. This one consists of a long chain of compounds called cresol groups linked in a polymer. Cresol contains reactive(易反应的) components that make it highly unstable in its polymeric form, a feature Almutairi and her colleagues use to their advantage. After polymerizing the cresols, they cap each reactive component with a light-absorbing compound called Bhc. When the Bhcs absorb NIR light, the reactive groups are exposed and break the long polymer into two short chains. Shining additional light continues this breakdown, potentially releasing any drugs in the capsule. What's more, Almutairi says, Bhc is 10 times better at absorbing NIR than is ONB and is not poisonous to cells.
【小题1】According to the passage, which of the following could be the best trigger?

A．Temperature change.

B．NIR light.

C．Acidity change.

D．UV light.

【小题2】Why in ONB unsatisfactory?

B． It falls off the polymer and triggers drug release.

C． It has not come onto the market up till now.

D． It is not effective enough and could be poisonous.

【小题3】Which word can be used to complete the following process of changes?

A．protected

B．formed

C．exposed

D．combined

winter-swimming has become popular in Beijing. three years ago, few people would go swimming in the city waters. but now there is a winter-swimming
enthusiasts’club(冬泳爱好者协会)and it has more than 2,000 members. the oldest is 84 years of age and the youngest is only 7. The members are from all walks of life. They may be workers, peasants, soldiers, teachers, students....Though it is now the coldest part of the season and the water temperature in the city’s lakes is around 0°c, many winter-simmers still swim in the icy waters, even when it is snowing. They enjoy themselves in the lake, while the people by the side of the lake are wearing heavy clothes.
why are so many people interested in winter-swimming? Because winter-swimming can be good for one’s health.
Bei Sha is a good example. He is 69 years old, and he once suffered from heart trouble for 26 years. After ten years of winter-swimming he is now in good health. Scientists are now studying the effects of winter-swimming on health.

Below is some advice on how to prevent cancer:
8 Ways to Avoid Cancer in Your Life
1. Eat Blueberries
Aside from being a healthy and delicious snack, blueberries contain pterostilbene, which has important colon（结肠） cancer-fighting prosperities. But wait, it gets better. Blueberries also offer a large dose of vitamins C (14 milligrams per cup). So at breakfast, try to take in a cup and a half of blueberries in your cereal or yogurt, or mixed with other berries.
2. Drink Pomegranate（石榴）Juice
The deep red juice of the pomegranate contains polyphenols, isoflavones and ellagic acid, which together create a powerful anticancer mixture. Most recently, researchers from the University of Wisconsin at Madison has discovered that 16 ounces of pomegranate juice per day also may inhibit the growth of lung cancer.
3. Relax
Feeling stressed or worried? Find ways to relax and you may reduce your chances of developing cancer. Purdue University researchers tracked 1,600 men over 12 years and found that half of those with high levels of worry died during the study period. Only 20 percent of the optimists died before the study were completed, while 34 percent of the extremely anxious men died of some type of cancer. Instead of stressing about the past or future, focus on the present and relax!
4. Take Selenium（硒）
Selenium is well known for its cancer-fighting properties. In a study of almost 1,000 men, researchers from the Journal of the National Cancer Institute found that when men with the lowest initial levels of selenium in their bodies received a daily supplement over a 4 year period, they cut their prostate（前列腺） cancer risk by a remarkable 92 percent. However, it is possible to get too much of a good thing, so monitor your intake of selenium-containing supplements, Brazil nuts, tuna, meats and grains carefully.
5. Eat Sushi（寿司）
Seaweed may not be your idea of a great snack, but it is high in fiber, calcium and iron, and dry, roasted seaweed sheets used in sushi provide the additional benefits of vitamins A and C. Sushi rolls are also high in protein— a typical spicy tuna roll has only 290 calories but packs 24 grams of protein. So don’t skimp（节省）on the Sushi!
6. Enjoy the Outdoors
Vitamin D causes early death of cancer cells. A study published in the American Journey of Clinical Nutrition reported that women who supplemented their diets with 1,000 international. Units of vitamin D every day had a 60 percent to 77 percent lower incidence of cancer ever a four-year period that did women taking a placebo(无效对照剂). Experts recommend supplementing your fun in the sun with 1,100 to 2,000IU of vitamin D each day.
7. Breathe Clean Air
There’s no question that secondhand smoke kills. A recent American Journal of Public Health study showed that nonsmokers working in smoky places had three times the amount of carcinogen（致癌物质） in their urine（尿） than nonsmokers working in smoke-free locations. What’s worse, their levels of the carcinogen rose 6 percent for every hour worked. Nine states have banned smoking in all workplaces, bars and restaurants. The message is clear: Do whatever you can to avoid the cloud of smoke.
8. Break a Sweat
Even a small amount of exercise can offer major cancer-fighting benefits. In a study of 29,110 men published in the International Journal of Cancer, men who exercised just once a week had a percent lower risk of metastasis(转移性) prostate cancer than men who didn’t work out at all. The better the frequency, duration and intensity of the exercise, the bigger the reduction in risk, according to the study.

Most people feel lonely sometimes，but it usually only lasts between a few minutes and a few hours，This kind of loneliness is not serious．In fact，it is quite normal．For some people，though，loneliness can last for years．Now researchers say loneliness comes in three different types．
The first kind of loneliness is temporary．This is the most common type．It usually disappears quickly and does not require any special attention．The second kind is situation，for example，family problem，the death of a loved one，or moving to a new place．Although this kind of loneliness can cause physical problems，such as headaches and sleeplessness，it usually does not last for more than a year．The third kind of loneliness is the most serious．Unlike the second type, chronic (the opposite of‘temporary’) usually lasts more than two years and has no specific cause．People who experience habitual loneliness have problems socializing and becoming close to others．Unfortunately，many chronically lonely people think there is little or nothing they can do to improve their condition．
Psychologists(心理学家) agree that one important factor in loneliness is a person’s social contacts，for example，friends，family members，co-workers，etc．We depend on various people for different reasons．For instance．our family give us emotional support，our parents and teachers give us guidance, and our fiends share similar interests and activities．
However，psychologists have found that, though lonely people may have many social contacts，they sometimes feel they should have more．They question their popularity．
Psychologists are trying to find ways to help habitually lonely people for two reasons：they are unhappy and unable to socialize arid there is a connection between chronic loneliness and serious illness such as heart disease，while temporary and situational loneliness can be a sad，and sometimes dangerous condition．
【小题1】How would you treat temporary loneliness according to the passage?

A．Talk to friends．

B．Go to see a doctor．

C．Just ignore it．

D．Ask your teacher for guidance．

【小题2】Why do psychologists want to help chronically lonely people?

A．Chronic loneliness can cause family problems．

B．Chronic loneliness is incurable．

C．Chronic loneliness can not be overcome．

D．Chronic loneliness call cause serious illness．

【小题3】Loneliness is divided according to ________．

A．the time it lasts

B．the places where it appears

C．different people it happen to

D．different seasons when it appears
