问题：共用题干 Promising Resnlts from Cancer StudyA new experimental vaccine（疫苗）has shown promising results in the fight against lung cancer.In a small Texas-based study,a vaccine developed by scientists at Baylor University Medical Centre in Dallas,USA,cured lung cancer in some patients and slowed the progress of the disease in others.Researchers have reported encouraging findings from this small study.Forty一three patients suffering from lung cancer were involved in these trials.Ten of these patients were in the early stages and thirty-three in tho advanced stages of the disease.They were injected with the vaccine every two weeks for three months,and were carefully monitored for three years.In three of the patients in the advanced stages of cancer,the disease disappeared and in the others,it did not spread for five to twenty-four months.However,no great difference was seen in the patients in the early stages of the illness.This new vaccine uses the patient's own immune system.It is made specifically for each patient and is injected into the arm or leg.It stimulates（刺激）the body's immune system, which then recognizes that the cancer cells are harmful,and attacks and destroys them.The vaccine could be effective against other forms of cancer.It offers great hope for the treatment of cancer in general,although further studies are needed before such treatment can be widely used.All the patients were from Dallas.A:RightB:WrongC:Not mentioned
问题：共用题干 Relieving the Pain"Exercise may be the best treatment of chronic pain,"say doctors at a new clinic for dealing with pain. "People with chronic pain need to stop lying around,go out more,and start exercising."The instinctive reaction to acute pain is to stop moving and to try to protect the source of pain. But it seems that this is often not productive,especially in the case of back pain. Back pain,after headaches and tiredness,has become the third most common reason for people to visit their doctors.Painful backs now account for millions of days off work.Lumbar（腰部的）pains are partly the price humans pay for taking their forelimbs off the ground, but they are made worse by a sedentary（久坐不动的）lifestyle. Lack of exercise slowly decreases the flexibility and strength of muscles,so that it is more difficult to take pressure off the site of pain.Exercise is essential. It releases endorphins（内啡肽）,the body's "feel-good" chemicals, which are natural painkillers. In fact, these are so important that researchers are now looking for drugs that can maintain a comfortable level of endorphins in the body.Most people who go to a family doctor complaining of pain are prescribed pain-killing drugs rather than exercise.Since finding the cause of backache is not so easy,doctors frequently do not know the precise cause of the discomfort,and as the pain continues,sufferers end up taking stronger doses or a series of different drugs."It's crazy,"says Dr. Brasseur,a therapist at the International Association for the Study of Pain. "Some of them are taking different drugs prescribed by different doctors.I've just seen a patient who was taking two drugs which turned out to be the same thing under different names."A generation of new pain clinics now operates on the basis that drugs are best avoided.Once patients have undergone the initial physical and psychological check up,their medication is cut down as much as possible.Taking patients off drugs also prepares them for physical activity.In some pain一 relief clinics,patients begin the day with muscle contraction and relaxation exercises, followed by an hour on exercise bikes. Later in the day,they practice tai chi（太极）,self-defense,and deepthought. This compares with an average of two-and-a-half hours' physiotherapy（理疗）a week in a traditional hospital program."The idea is to strengthen and to increase long一lasting energy,flexibility,and confidence," explains Bill Wiles,a consultant pain doctor in Liverpool."Patients undergoing this therapy get back to work and resume healthy active lifestyles much sooner than those subjected to more conservative treatment."Headaches are partly caused by lack of exercise.A:RightB:WrongC:Not mentioned

问题：共用题干 Warm People Likely to Keep Cold at BayStaying positive through the cold season could be your best defense 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 ward off the common cold and other illnesses.Researchers believe the reasons may be both objective as in happiness boosting immune function and subjective as in happy people being less troubled by a scratchy throat or runny 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 susceptible to catching 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 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.The researchers chose 193 adults who had a negative style for the study.A:Right B:Wrong C:Not mentioned
问题：共用题干 Most of us walk and carry items in our hands every day.These are seemingly simple activities that the majority of us don't question.But an international team of researchers,including Dr. Richmond from GW's Columbian College of Arts and Sciences,have discovered that human walking upright, may have originated millions of years ago as an adaptation to carrying scarce（稀有的）,high-quality resources.The team of researchers from the U.S.,England,Japan and Portugal investigated the behavior of modern-day chimpanzees（黑猩猩）as they competed for food resources,in an effort to understand what ecological settings would lead a large ape（类人猿）一one that resembles the 6 million-year old ancestor we shared in common with living chimpanzees一to walk on two legs."These chimpanzees provide a model of the ecological conditions under which our earliest ancestors might have begun walking on two legs",said Dr. Richmond.The research findings suggest that chimpanzees switch to moving on two limbs instead of four in situations where they need to monopolize a resource.Standing on two legs allows them to carry much more at one time because it frees up their hands. Over time , intense bursts of bipedal（二足的）activity may have led to anatomical（解剖学的）changes that in turn became the subject of natural selection where competition for food or other resources was strong.Two studies were conducted by the team in Guinea. The first study was conducted by the team in Kyoto University's "outdoor laboratory" in a natural clearing in Bossou Forest. Researchers allowed the wild chimpanzees access to different combinations of two different types of nut一the oil palm nut,which is naturally widely available,and the coula nut,which is not.The chimpanzees' behavior was monitored in three situations:(a)when only oil palm nuts were available,(b)when a small number of coula nuts were available,and(c)when coula nuts were the majority available resource.When the rare coula nuts were available only in small numbers,the chimpanzees transported more at one time.Similarly,when coula nuts were the majority resource,the chimpanzees ignored the oil palm nuts altogether. The chimpanzees regarded the coula nuts as a more highly-prized resource and competed for them more intensely.In such high-competition settings,the frequency of cases in which the chimpanzees started moving on two legs increased by a factor of four. Not only was it obvious that bipedal movement allowed them to carry more of this precious resource,but also that they were actively trying to move as much as they could in one go by using everything available一even their mouths.The second study,by Kimberley Hockings of Oxford Brookes University,was a 14-month study of Bossou chimpanzees crop-raiding,a situation in which they have to compete for rare and unpredictable resources.Here,35 percent of the chimpanzees activity involved some sort of bipedal movement,and once again,this behavior appeared to be linked to a clear attempt to carry as much as possible at one time.Walking on two limbs and walking on four limbs each have their advantages.A: Right B:Wrong C:Not mentioned

问题：共用题干 The World's Best-Selling MedicineSince ancient times,people all over the world have used willow to stop pain. The willow tree contains salicylic acid（水杨酸）.This stops pain, but there is one problem. Salicylic acid also hurts the stomach. In 1853,a French scientist made a mixture from willow that did not hurt the stomach.However,his mixture was difficult to make,and he did not try to produce or sell it.In 1897,in Germany,Felix Hoffmann also made a mixture with salicylic acid. He tried it himself first and then gave it to his father because his father was old and in a lot of pain.His father's pain went away,and the mixture did not hurt his stomach.Hoffmann worked for Bayer,a German company. He showed his new drug to his manager,who tested the drug and found that it worked well.Bayer decided to make the drug.They called it aspirin and put the Bayer name on every pill.Aspirin was an immediate success. Almost everyone has pain of some kind,so aspirin answered a true need. Aspirin was cheap,easy to take,and effective. It also lowered fevers.Aspirin was a wonder drug.At first,Bayer sold the drug through doctors,who then sold it to their patients. In 1915,the company started to sell aspirin in drugstores.In the United States,Bayer had a patent（专利权）on the drug. Other companies could make similar products and sell them in other countries,but only bayer could make and sell aspirin in the United States.In time,Bayer could no longer own the name aspirin in the United States. Other companies could make it there,too.However,Bayer aspirin was the most well known,and for many years,it was the market leader.By the 1950s,new painkillers were on the market. Aspirin was no longer the only way to treat pain and reduce fever. Bayer and other companies looked for other drugs to make.However,in the l970s they got a surprise. Doctors noticed that patients who were taking aspirin had fewer heart attacks than other people. A British researcher named John Vane found the reason aspirin helped to prevent heart attacks.In 1982,he won the Nobel prize for his research. Doctors started to tell some of their patients to take aspirin every day to prevent heart attacks.It has made life better for the many people who take it. It has also made a lot of mon-ey for companies like Bayer that produce and sell it!What has happened to aspirin since new painkillers came on the market?A: Companies have stopped selling it.B: It has become the best-selling painkiller.C: Its new use has been discovered.D: Doctors have sold it to patients.

问题：共用题干 第一篇Most young people enjoy some form of physical activity.It may be walking,cycling or swimming,or in winter,skating or skiing. It may be a game of some kind of football,hockey,golf, or tennis.It may be mountaineering.Those who have a passion for climbing high and difficult mountains are often looked upon with astonishment.Why are men and women willing to suffer cold and hardship,and to take risks on high mountains?This astonishment is caused probably by the difference between mountaineering and other forms of activity to which men give their leisure.Mountaineering is a sport and not a game.There are no manmade rules,as there are for such games as golf and football.There are,of course,rules of a different kind which it would be dangerous to ignore,but it is this freedom from man-made rules that makes mountaineering attractive to many people.Those who climb mountains are free to use their own methods.If we compare mountaineering and other more familiar sports,we might think that one big difference is that mountaineering is not a"team game".We should be mistaken in this.There are,it is true,no "matches " between "teams"of climbers,but when climbers are on a rock face linked by a rope on which their lives may depend,there is obviously teamwork.The mountain climber knows that he may have to fight forces that are stronger and more powerful than man.He has to fight the forces of nature.His sport requires high mental and physical qualities.A mountain climber continues to improve the skill year after year. A skier is probably past his best by the age of thirty,and most international tennis champions are in their early twenties.But it is not unusual for a man of fifty or sixty to climb the highest mountains in the Alps.They may take more time than younger men,but they probably climb with more skill and less waste of effort,and they certainly experience equal enjoyment.Mountaineering can be called a team sport because_________.A:it is an Olympic eventB:teams compete against each otherC:mountaineering depends on each other while climbingD:there are S climbers on each team

问题：共用题干 More About Alzheimer 's DiseaseScientists have developed skin tests that may be used in the future to identify people with Alzheimer's disease and may ultimately allow physicians to predict who is at risk of getting this neurological（神经病学的）disorder.The only current means of diagnosing the disease in a living patient is a long and expensive series of tests that eliminate every other cause of dementia. "Since Alois Alzheimer described the disease nearly a century ago,people have been trying to find a way to accurately diagnose it in its early stages,"said Patricia Grady,acting director of the National Institute of Neurological Disorders and Stroke in Bethesda,Maryland."This discovery,if confirmed,could prove a big step forward in our efforts to deal with and understand the disease."Alzheimer's is the single greatest cause of mental deterioration in older people,affecting between 2.5 million and 4 million people in the United States alone.The devastating disorder gradually destroys memory and the ability to function,and eventually causes death.There is currently no known treatment for the disease.Researchers discovered that the skin cells of Alzheimer’s patients have defects that interfere with their ability to regulate the flow of potassium in and out of the cells.The fact that the cell defects are present in the skin suggests that Alzheimer's results from physiological changes throughout the body,and that dementia may be the first noticeable effect of these changes as the defects affect the cells in the brain,scientists said.The flow of potassium is especially critical in cells responsible for memory formation.The scientists also found two other defects that affect the cells'supply of calcium,another critical element.One test developed by researches calls for growing skin cells in a laboratory culture and then testing them with an electrical detector to determine if the microscopic tunnels that govern the flow of potassium are open.Open potassium channels create a unique electrical signature.A spokesman for the Alzheimer's Association said that if the validity of the diagnostic test can be proven it would be an important development,but he cautioned that other promising tests for Alzheimer's have been disappointing.The newly developed skin tests may be used in the future to allow doctors to______.A:cure those with Alzheimer's diseaseB:discover the cause of Alzheimer's diseaseC:predict who might get Alzheimer's diseaseD:find the consequences of Alzheimer's disease
问题：共用题干 Retirement Brings Most a Big Health BoostThe self-reported health of the newly retired improves so much that most feel eight years younger,a new European study suggests.This happy news was true of almost everyone except a small minority一only 2 percent一who had experi- enced"ideal"conditions in their working life,anyway."The results really say three things:that work puts an extra burden on the health of older workers,that the effects of this extra burden are largely relieved by retirement and,finally,that both the extra burden and the relief are larger when working conditions are poor,"said Hugo Westerlund,lead author of a study pub- lished online Nov. 9 in The Lancet（柳叶刀）." This indicates that there is need to provide opportunities for older workers to decrease the demands in their work out of concern for their health and well-being."But of course,added Westerlund,who is head of epidemiology at the Stress Research Institute at Stockholm University in Sweden,"not all older workers suffer from poor perceived health.Many are indeed remarkably healthy and fit for work.But sooner or later,everyone has to slow down because of old age catch-ing up."Last week,the same group of researchers reported that workers slept better after retirement than before. "Sleep improves at retirement,which suggests that sleeping could be a mediator between work and perception of poor health,"Westerlund said.This study looked at what the same 15,000 French workers,and most of them had to say about their own health up to seven years pre-retirement and up to seven years post-retirement.As participants got closer to retirement age,their perception of their own health declined,but went upagain during the first year of retirement.Those who reported being in poorer health declined from 19.2 percent in the year prior to retirement to 14.3 percent by the end of the first year after retiring. According to the researchers,that means post-retire- ment levels of poor health fell to levels last seen eight years previously.The changes were seen in both men and women,across different occupations,and lasted through the first seven years of not punching the clock.Workers who felt worse before retirement and had lower working conditions reported greater improve- ments as soon as they retired,the team found.Europe is aging faster than most other parts of the globe.A:RightB:WrongC:Not mentioned
