    In the rush to get to school, you drop a piece of toast on the floor. Do you throw it away or decide it’s still OK to eat? If you’re like most people, you eat it. Maybe you follow the “5-second rule”, which claims foods are safe to eat if you pick them up within 5 seconds after dropping them.      
    But you might want to think again. Scientists now say that 5 seconds is all it takes for foods to become polluted with enough bacteria（细菌）to make you sick.
    Bacteria can cause many kinds of illnesses. Some kinds of bacteria can grow on food. If you eat foods on which these bacteria are growing, you can become sick.
    One of these food-borne bacteria is Salmonella. It makes 1.4 million people sick every year. Salmonella is often found in raw eggs and chicken. Cooking kills these bacteria, which is why it is so important to cook eggs, chicken, and other foods thoroughly.
    But how long does it take these bacteria to pollute food? A team of scientists in South Carolina did an experiment. First, they placed an amount of Salmonella on three surfaces; wood, tile (瓦片), and carpet. They placed a piece of bread and a piece of bologna（一种大红肠）on each surface for 5, 30, or 60 seconds. After just 5 seconds, both the bread and the bologna picked up enough bacteria to make you sick.
    So, forget the 5-second rule. If your toast drops on the floor, throw it away and get another piece of clean toast. And this time, be careful not to drop it!
    小题1:In which part of a newspaper can you most probably find this passage?
    A．CultureB．HealthC．AdvertisementD．Technology
    小题2:After dropping a piece of toast, a person who follows the “5-second rule” will         .
    A．throw away dirty toast immediately and go away
    B．pick up the toast as quickly as possible and eat it
    C．eat the toast within 5 seconds and feel pleased
    D．get another piece of clean toast quickly and eat it
    小题3:The scientists in South Carolina did the experiment to __________ .
    A．see how quickly bacteria can pollute food
    B．show that the 5-second rule is correct
    C．see how harmful bacteria are to people’s health
    D．show that bacteria grow at different speeds on different foods

    Coffee experts are willing to pay large sums of money for high-quality coffee beans. The high-end beans, such as Kona or Blue Mountain, are known to cost extraordinary sums of money. Then there is Kopi Lowak (translated as “Civet Coffee”), the world’s most expensive coffee, which sells for as much as US $50 per quarter-pound.
    This isn’t particularly surprising, because approximately 500 pounds a year of Kopi Lowak make up the entire world supply. What is surprising is why this particular coffee is so rare. In fact, it’s not the plants that are rare. It’s the civet droppings. That’s right, the civet droppings—the body waste of the palm civet. Coffee beans aren’t Kopi Lowak until they’ve been digested(消化) and come out in the body waste of the palm civet.
    Palm civets are tree-dwelling, raccoon-like little animals, native to Southeast Asia and the Indonesian islands. They also have a love for coffee cherries. According to Kopi Lowak suppliers, palm civets eat the fruit whole, but only digest the outer fruit, leaving the beans intact(完好无损). While the beans are not destroyed, they undergo a transformation in the animal’s body. A chemical substance in the digestive system of the palm civet causes some changes to the beans to give them a unique flavor(味道). However, this is not the only explanation why coffee beans retrieved from civet droppings have a special flavor all their own. Another possible reason is that palm civets have an unfailing instinct for picking the coffee cherries at the peak of their ripeness.
    Kopi Lowak is reported to have a character in taste unlike any other coffee, complex with caramel undertones and an earthy flavor. Currently, most of the world’s supply of Kopi Lowak is sold in Japan, though a few US markets are also starting to stock up on Kopi Lowak.
    小题1:What does “This” in the second paragraph refer to?
    A．Civet Coffee.B．Blue Mountain coffee.
    C．The high price of Kopi Lowak.D．The unique taste of Kona.
    小题2:Why is Kopi Lowak expensive?
    A．There is a very limited supply of the beans.
    B．The coffee trees that grow the beans are scarce.
    C．It takes a long time for the coffee beans to ripen.
    D．Only a few experts know how to produce the beans.
    小题3:What is the main point discussed in the third paragraph?
    A．Why palm civets like the coffee beans.
    B．Where Kopi Lowak is mainly harvested.
    C．What chemicals are found in the civet’s digestive system.
    D．How palm civets change coffee fruit to Kopi Lowak beans.
    小题4:Which of the following statements is true, according to the passage?
    A．Little palm civets eat only the outer layer of the coffee cherries.
    B．Palm civets somehow know the right time when the coffee fruit ripens.
    C．Kopi Lowak is most popular in Southeast Asia and the Indonesian islands.
    D．Kona and Blue Mountain are the most expensive coffees but only of average quality.

    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.

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.

    Is there anything more important than health? I don’t think so. “Health is the greatest wealth(财富),” wise people say. You can’t be good at your studies or work well when you are ill.
    If you have a headache, toothache, backache, earache or bad pain in the stomach, if you complain of a bad cough, if you run a high temperature and have a bad cold, or if you suffer from high or low blood pressure, I think you should go to the doctor.
    The doctor will examine your throat, feel your pulse, test your blood pressure, take your temperature, sound your heart and lungs, test your eyes, check your teeth or have your chest X-rayed. After that he will advise some treatment, or some medicine. The only thing you have to do is to follow his advice.
    Speaking about doctor’s advice, I can’t help telling you a funny story.
    An old gentleman came to see the doctor. The man was very ill. He told the doctor about his weakness, memory loss and serious problems with his heart and lungs. The doctor examined him and said there was no medicine for his disease.
    He told his patient to go to a quiet place for a month and have a good rest. He also advised him to eat a lot of meat, drink two glasses of red wine every day and take long walks. In other words, the doctor advised him to follow the rule: “Eat at pleasure, drink with measure and enjoy life as it is.” The doctor also said that if the man wanted to be well again, he shouldn’t smoke more than one cigarette a day.
    A month later the gentleman came into the doctor’s office. He looked cheerful and happy. He thanked the doctor and said that he had never felt a healthier man.

    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.

    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.

    Ever since they were first put on the market in the early 1990s, gentically mondified (GM, 转基因) foods have been increasingly developed and marketed in many countries in the word,mainly on the basis of their promise to end the worldwide food crisis. But can GM technology solve world hunger problems? Even if it would ,is it the best solutiorr?
    Despite what it promiises,GM  technology actually has not increased the production potential    of any corp. In fact
    Studies show that the most  crown GM croo.
    GM soybeans, has suffered reduced productivity. For instance, a report than analysed nearly two decades of research on mojor GM food crops shows that GM engineering has failed to significantly increase US crop production.
    Something else, however, has been on the rise, While GM seeds are expensive, GM companics tell farmers that they will make good profits by saving money on pesticides（杀虫剂）. On the contrary, US government data show that GM crops in the US have produced an overall increase in pesticide use compared to traditional crops. “ The  promise was that you could use less chemicals and boost production. But nether is true,” said Bill Christison, President of the US National Farm Coalition.
    At the same time, the authors of the book World Hunger: Twelve Myths argue that there actually is more than enough food in the world and that the hunger crisis is not caused by production, but by problems in food distribution and politics. These indeed deserve our efforts and money. Meanwhile, the rise in food prices results from the increased use of crops for fuel rather than food, according to a 2008 World Bank report.
    As a matter of fact ,scientists see better ways to feed the world. Another World Bank report concluded that GM crops have little to offer to the challenges of worldwide poverty and hunger, because better ways out are available, among which “green” farming is supposed to be the first choice.
    小题1:The author develops the second paragraph mainly       .            
    A．by classificationB．by comparison
    C．by exampleD．by process
    小题2:What does the underlined word “boost ” in the third paragraph probably mean?
    A．Control.B．EvaluateC．Obtain.D．Increase.
    小题3: GM companies promise farmers that they will benefit from ______________.   
    A．practicing “green” farmingB．use of less chemicals
    C．fair distribution of their cropsD．using more crops for fuel
    小题4:Which of the following best describes the attitude of the author towards GM technology?

    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

    Malnutrition (营养失调)remains a serious problem for India. But a new study shows that India’s leading causes of death now also include diseases related to obesity （肥胖）such as heart disease.
    India’s National Family Health Survey shows that more than twenty percent of Indians living in cities are overweight or obese. And in the northwestern state of Punjab, that is true for almost forty percent of women.
    Aradhna Tripathi is a business professional in New Delhi. She said, “ Eating is the most important thing in any Indian household and how you show your love and gratitude(感激) for a person is through the kind of food you serve him. And the kind of lifestyle we are leading is one of the reasons why we have the number of obese people increasing every day.
    But Aradhna Tripathi says she has decided to lose weight. Her mother and grandmother are also diabetic(患糖尿病的). In fact, the International Diabetes Federation says India is now the diabetes capital of the world. Researchers say Indians store more body fat per kilogram than Europeans. That means obese Indians are even more at the risk of diabetes than other people.
    Doctor Anoop Misra at Fortis Hospital in New Delhi says the risk of diabetes is crossing social and economic lines. Five years ago, he says, obesity and diabetes were limited to India’s richest people, but now things have changed.
    But Doctor Misra is hopeful that the spread (蔓延，传播)of obesity can be slowed. And he says it must start in schools by giving all Indian children the same instruction on physical activity and diet.
    The World Health Organization says China is also moving up in obesity rates. The estimate (估计) has reached about five percent countryside and as high as twenty percent in some cities.
    小题1:What is this passage mainly about?
    A．Obesity has become a big killer in India.
    B．Heart disease is troubling people in India.
    C．People in India live a very unhealthy life.
    D．Malnutrition remains a serious problem in India.
    小题2:According to Aradhna Tripathi , one of the causes of the obesity problems is_________.
    A．.the development of economy
    B．the change of Indians’ lifestyle
    C．Indians’ attitude （态度）towards eating
    D．Indians’ attitude towards obesity.
    小题3: What can we infer from the underlined sentence in Paragraph 5?
    A．Most wealthy people in India are overweight.
    B．Five years ago, few people in India were overweight
    C．Few poor people are diabetic for economic reasons.
    D．Now even the poor in India suffer from obesity.
