Our risk of cancer rises dramatically as we age. So it makes sense that the elderly should be routinely screened for new tumors — or doesn’t it?
　　While such vigilant(警觉的)tracking of cancer is a good thing in general, researchers are increasingly questioning whether all of this testing is necessary for the elderly. With the percentage of people over age 65 expected to nearly double by 2050, it’s important to weigh the health benefits of screening against the risks and costs of routine testing.
　　In many cases, screening can lead to additional biopsies and surgeries to remove cancer, which can cause side effects, while the cancers themselves may be slow-growing and may not pose serious health problems in patients’ remaining years. But the message that everyone must screen for cancer has become so ingrained that when health care experts recommended that women under 50 and over 74 stop screening for breast cancer, it caused a riotous reaction among doctors, patients and advocacy groups. 
　　It’s hard to uproot deeply held beliefs about cancer screening with scientific data. Certainly, there are people over age 75 who have had cancers detected by routine screening, and gained several extra years of life because of treatment. And clearly, people over age 75 who have other risk factors for cancer, such as a family history or prior personal experience with the disease, should continue to get screened regularly. But for the remainder, the risk of cancer, while increased at the end of life, must be balanced with other factors like remaining life expectancy(预期寿命).
　　A recent study suggests that doctors start to make more objective decisions about who will truly benefit from screening- especially considering the explosion of the elderly that will soon swell our population.
　　It’s not an easy calculation to make, but one that make sense for the whole patient. Dr. Otis Brawley said, “Many doctors are ordering these tests purely to cover themselves. We need to think about the rational use of health care and stop talking about the rationing of health care.”
　　That means making some difficult decisions with elderly patients, and going against the misguided belief that when it comes to health care, more is always better.

Happiness is contagious (有感染力的), as researchers reported on Thursday.
People with the most social connections — spouses, friends, neighbors and relatives — were also the happiest, the data showed. “Each additional happy person makes you happier,” Christakis said.
“Imagine that I am connected to you and you are connected to others and others are connected to still others. It is this fabric of humanity, like an American patch quilt.”
Each person sits on a different colored patch. “Imagine that these patches are happy and unhappy patches. Your happiness depends on what is going on in the patch around you,” Christakis said.
“It is not just happy people connecting with happy people, which they do. Above and beyond, there is this contagious process going on.”
And happiness is more contagious than unhappiness, they discovered.
“If a social contact is happy, it increases the likelihood that you are happy by 15 percent, ” Fowler said. “A friend of a friend, or the friend of a spouse or a sibling (兄弟姐妹), if they are happy, increases your chances by 10 percent,” he added.
A happy third degree friend — the friend of a friend of a friend — increases a person’s chances of being happy by 6 percent.
“But every extra unhappy friend increases the likelihood that you’ll be unhappy by 7 percent,” Fowler said.
The finding is interesting and it is useful, too, Fowler said.
“Among other benefits, happiness has been shown to have an important effect on reduced mortality (死亡率), pain reduction, and improved cardiac (心脏的) function. So better understanding of how happiness spreads can help us learn how to develop a healthier society,” he said.
The study also fits in with other data suggested in 1984 that having $ 5,000 extra increased a person’s chances of becoming happier by about 2 percent.
“A happy friend is worth about $ 20,000,” Christakis said.
小题1:It can be inferred that________.
A．happiness spreads as fast and widely as unhappiness
B．unhappiness spreads faster and more widely than happiness
C．happiness spreads faster and more widely than unhappiness
D．the spread of unhappiness has not been studied by researchers
小题2:Which of the following will increase your chances of becoming happier most?
A．Being in a party with a happy atmosphere.
B．A happy experience of your brother or your parents.
C．A happy trip to a foreign country of your friends.
D．Happiness of your friend’s friend.
小题3:What does Christakis mean by saying “A happy friend is worth about $ 20,000”?
A．A happy friend can help you bring in a wealth of $ 20,000.
B．A happy friend is a wealth which is worth about $ 20,000.
C．A happy friend increases your chances of being happy by 2%.
D．A happy friend increases your chances of being happy by 8 %.

An Australian researcher is urging parents to load up their teenager’s backpack and make them walk to school.
Professor Leon Straker says students who walk or cycle to school are less likely to have back and neck pain. But the study of 1,202 Western Australian 14­year­old found that 72% of students travelled to school by car or bus. Straker says the study suggests walking or cycling while carrying a schoolbag helps improve trunk (躯干) and spinal (脊柱的) muscle strength.
This helps reduce back pain because greater muscle strength improves support for the back during load carrying .Despite advocating that parents get their children moving，Straker warns bag load should not exceed (超过) 15% of body weight.
Straker says the study also stresses that neck pain is as common as back pain among young teenagers. This is an area that has been largely ignored，he says，but can be an important indicator of neck pain into adulthood.
For the study，students were asked a series of questions such as how long they carried their bags for，how they carried their schoolbags，the method of travel，and their perceptions(感觉) about the bag’s weight.
Straker says about half of all participants experienced back and neck pain，with slightly more females reporting neck pain. However，the gender (性别) difference may also be due to the fact that females have lower pain tolerance.
Studies from the 1980s found carrying a bag over one shoulder was most common among teenagers. However in this study 85% of participants carried their bag over both shoulders.
Straker believes the change has been driven partly through education campaigns，but also by increasing fashion status of backpacks and improved design.
小题1:In the opinion of Leon Straker，parents should________.
A．reduce the load of their children’s schoolbags
B．put more books in their children’s schoolbags
C．get their children’s schoolbags ready for school
D．ask their children to walk to school carrying schoolbags
小题2:If a child weighs 40 kilograms，the weight of his schoolbag should be________.
A．no more than 15 kg
B．less than 6 kg
C．as heavy as 9 kg
D．more than 6 kg
小题3:We can learn from the passage that________.
A．most of the students in Australia walk to school
B．neck pain is uncommon among young teenagers
C．walking while carrying a backpack helps reduce back pain
D．males are more likely to experience back pain than females
小题4:According to the passage，what change has taken place since the 1980s?
A．How students carry their schoolbags.
B．How heavy students’ schoolbags are.
C．How students go to school every day.
D．How long students carry their schoolbags for.
Up to 90% of school leavers in major Asian cities are suffering from myopia ---short-sightedness, a study suggests. Researchers say the "extraordinary rise" in the problem is being caused by students working very hard in school and missing out on outdoor light.
Eye experts say that you are short-sighted if your vision is blurred(模糊的) beyond 2m. It is often caused by an elongation（拉伸） of the eyeball that happens when people are young. According to the research, the problem is being caused by a combination of factors - a commitment to education and lack of outdoor light.
Professor Morgan who led this study argues that many children in South East Asia spend long hours studying at school and doing their homework. This in itself puts pressure on the eyes, but exposure to between two and three hours of daylight helps maintain healthy eyes.
Cultural factors also seem to play a part. Across many parts of South East Asia, children often have a lunchtime nap. According to Professor Morgan they are missing out on natural light to prevent short-sightedness.
A big concern is the numbers of the students suffering from “high” myopia. One in five of these students could experience severe visual impairment(障碍) and even blindness. These people are at considerable risk—sometimes people are not told about it and are just given more powerful glasses—they need to be warned about the risk and given some self-testing measures so they can get to an ophthalmologist and get some help.
For decades, researchers believed there was a strong genetic component to the condition. But this study strongly suggests an alternative view. “Any type of simple genetic explanation just doesn’t fit with that speed of change; gene pools just don’t change in two generations. Whether it’s a purely environmental effect or an environmental effect playing a sensitive genome, it really doesn’t matter, the thing that’s changed is not the gene pool---it’s the environment.”
小题1:As is mentioned above, which factor mainly results in students’ myopia in South East Asia?
A．Genetic faults of the people.B．Elongation of the eyeball.
C．The shortage of outdoor light.D．Lack of research into the problem.
小题2:Which of the following statements do you think agrees with Professor Morgan?
A．A lunchtime nap is helpful in reducing myopia.
B．Glasses keep myopia from getting even worse.
C．It’s necessary to treat myopia with an operation.
D．It’s of vital importance to reduce educational pressure.
小题3:What’s the main idea of the last paragraph?
A．Gene remains the main cause of the long-standing problem.
B．The environment is to blame for the extraordinary rise in myopia.
C．Short-sightedness has nothing to do with changes in gene pools.
D．An environmental effect playing a sensitive genome counts.
小题4:What’s the best way to take care of your eyes according to the passage?
A．Equip the classroom with better lights.
B．Look at the sun from time to time.
C．Do eyes exercise regularly.
D．Spend more time in the open air.
The food we eat seems to have a great effect on our health. Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of human illness is related to food and forty percent of cancer is related to food as well. That food is related to illness is not a new discovery. In 1945, some researchers realized that things commonly used to keep colour in meats and other food additives（添加剂）caused cancer.
Yet, these additives remain in our food, and it is difficult to know which things on the wrappings（包装）of foods are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to their animals, and because of this, penicillin has been found in the milk of cows. Sometimes similar tings are supplied to animals not for their health, but just to make a profit.
The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although some countries have tried to control such things, the practice continues.
小题1:Which of the following is not true?
A．Some wrappings of food are harmful.
B．Farmers try to make more money on the market by fattening their animals.
C．“The practice continues” means “things are still going on like that”.
D．We needn’t take care of what we eat.
小题2:According to this passage, we can know      .
A．perhaps most of human illness is caused by what we eat
B．perhaps most kinds of cancer are related to what people eat
C．cancer was discovered in 1945
D．science has made food unfit to eat
小题3:Things that are used to keep colours in meats are      .
A．harmfulB．uselessC．helplessD．dangerous
小题4:All the additives      .
A．are bright and colourless
B．are not bright and colourful
C．have indirect effects on our health
D．have direct effects on our health
After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the day. The rest that you get while sleeping makes it possible for your body to prepare itself for the next day.
There are four levels of sleep, each being a little deeper than the one before. As you sleep, your body relaxes (放松) little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts (变换) back and forth from one level of sleep to the other.
Though your mind slows down, you will dream from time to time. Scientists who study sleep point out that when dreaming occurs, your eyeballs begin to move more quickly (although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.
If you have trouble falling asleep, some people recommend (建议) breathing very slowly and very deeply. Other people believe that drinking warm milk will make you drowsy. There is also an old suggestion that counting sheep will put you to sleep.
小题1:The text suggests that not getting enough sleep might make you _____.
A．suffer from poor healthB．feel tired and nervous
C．dream more oftenD．breathe quickly
小题2:During REM, _____.
A．you move restlessly
B．you start dreaming
C．your mind stops working
D．your eyeballs move quickly
小题3:The underlined word "drowsy" in the last paragraph probably means _____.
A．lazyB．sleepyC．relaxedD．pleased
小题4:A good title for this text might be _____.
A．DreamsB．Sleep
C．Good HealthD．Work and Rest
The vitamins (维生素) are named by letters of the alphabet (字母表). Vitamin A is needed by the eyes. There is Vitamin A in milk, butter, and green vegetables. It can be kept by the body.
Vitamin B cannot be kept. It must be supplied all the time by some of the food we eat.
Vitamin C is very important to the body. Without it men’s teeth become loose (松的) and their arms and legs get weak. Lemons (柠檬), oranges and tomatoes have Vitamin C in them.
Vitamin D is the sun vitamin. We get it in milk and eggs and from sunlight on our skin (皮). There are other Vitamins, but these A, B, C and D, are the most important.
小题1:There are many kinds of vitamins, the most important of which are ______.
A．Vitamin AB．Vitamin B and C
C．Vitamin D and AD．Vitamin A ,B,Cand D
小题2:There are both Vitamins A and D in ______.
A．green vegetableB．sunlightC．butter and eggsD．milk
小题3:If somebody is near-eye sighted probably he needs ______. 
A．Vitamin AB．Vitamins A and CC．Vitamin DD．Vitamin B
小题4:We can get Vitamin D when ______.
A．we have bread and butter for our breakfastB．we are eating fruits
