共用题干Lung Cancer1 The death rate due to cancer of the lungs has increased more than 800 percent in males and has more than doubled in females during the last 25 years.It is considerably higher in urban and industrial areas than in rural districts.There are many possible causes,but it is still controversial which are most blameworthy.Those factors which have been mentioned most frequently are the presence of foreign particles and other irritants in the air(smoke particles,smog,exhaust fumes),and the smoking of cigarettes and cigars.2 Numerous studies have demonstrated a striking correlation between the death rate from lung cancer and smoking habits.Among heavy smokers-21 to 30 cigarettes per day-the mortality rate from lung cancer is nearly 17 times the rate from nonsmokers.It is expected the death rate among women will increase as the present high rate of smoking among women has its effect.3 Sometimes cases of lung cancer are discovered at the time an X-ray is taken for the purpose of detecting tuberculosis.Too often,however,a current emphasis upon the danger of exposure to radiation from x-ray machines can frighten people away from routine chest X-rays and thus prevent an early diagnosis of lung cancer.Early detection is absolutely essential if any possibility of cure is to be maintained.Modern X-ray machines in competent hands pose such slight danger,at least to those over 40 years of age,that this would be much more than offset by the advantages of discovering a tumor while it is small enough to be completely removed.4 A common form of lung cancer is bronchogenic carcinoma,so-called because the malignancy originates in a bronchus.The tumor may grow until the bronchus is blocked,cutting off the supply of air to that lung.The lung then collapses,and the secretions trapped in the lung spaces become infected,with a resulting pneumonia or the formation of a lung abscess.Such a lung cancer can also spread to cause secondary growths in the lymph nodes of the chest and neck as well as in the brain and other parts of the body.The only treatment that offers a possibility of cure,before secondary growths have had time to form,is to remove the lung completely.This operation is called pneumonectomy.5 Malignant tumors of the stomach,the breast,the prostate gland and other organs may spread to the lungs,causing secondary growths.People are still not sure______.A:before the cancer cells spread elsewhereB:the more chances of dying of X-ray radiation he will haveC:what is most responsible for lung cancerD:as some people imagineE:the more chances of getting lung cancer he will haveF:which form of lung cancer is a common one
共用题干第一篇In what may be bad news for bars and pubs,a European research group has found that people drinking alcohol outside of meals have a significantly higher risk of cancer in the mouth and neck than do those taking their libations with food.Luigino Dal Maso and his colleagues studied the drinking pattems of 1 ,500 patients from four cancer studies and another 3,500 adults who had never had cancer.After the researchers accounted for the amount of alcohol consumed,they found that individuals who downed a significant share of their alcohol outside of meals faced at least a 50 to 80 percent risk of cancer in the oral cavity（腔）,pharynx（咽）,and esophagus（食管）,when compared with people who drank only at meals.Consuming alcohol without food also increased by at least 20 percent the likelihood of laryngeal（喉）cancer."Roughly 95 percent of cancers at these four sites traced to smoking or drinking by the study volunteers,"Dal Maso says.The discouraging news,his team reports, is that drinking with meals didn't eliminate cancer risk at any of the sites.For their new analysis,the European scientists divided people in the study into four groups, based on how many drinks they reported having in an average week.The lowest-intake group includ-ed people who averaged up to 20 drinks a week.The highest group reported downing at least 56 servings of alcohol weekly for an average of eight or more per day.Cancer risks for the mouth and neck sites rose steadily with consumption even for people who reported drinking only with meals.For instance,compared with people in the lowest-consumption group,participants who drank 21 to 34 alcohol servings a week at least doubled their cancer risk for all sites other than the laryngeal cancer. If people in these consumption groups took some of those drinks outside meals,those in the higher consumption group at least quadrupled their risk for oral cavity and esophageal cancers.People in the highest-consumption group who drank only with meals had 10 times the risk of oral cancer,7 times the risk of pharyngeal cancer,and 16 times the risk of esophageal cancer compared with those who averaged 20 or fewer drinks a week with meals.In contrast,laryngeal cancer risk in the high-intake,with-meals-only group was only triple that in the low-intake consumers who drank with meals."Alcohol can inflame tissues.Over time,that inflammation can trigger cancer."Dal Maso says.He suspects that food reduced cancer risk either by partially coating digestive-tract tissues or by scrubbing alcohol off those tissues.He speculates that the reason laryngeal risks were dramatically lower for all study participants traces to the tissue's lower exposure to alcohol.Approximately how many drinks do the lowest-intake group average per day?A:3 drinks. B:8 drinks.C:20 drinks. D:56 drinks.

In addition,the report revealed that smoking three or four cigars a day increased the risk of oral cancer to 8.5 times the risk for nonsmokers and the risk of esophageal cancer by four times the risk of nonsmokers.The health effects of smoking cigars is one of eight sections of the article"Cigars:HealthEffects and Trends".The researchers report that,compared with a cigarette,a large cigar emits up to 90 times as much carcinogenic tobacco-specific nitrosamines."This article provides clear and invaluable information about the disturbing increase in cigar use and the significant public health consequences for the country,"said Dr. Richard Klausner, director of the National Cancer Institute,in a statement."The data are clear-the harmful substances and carcinogens in cigar smoke,like cigarettes,are associated with the increased risks of several kinds of cancers as well as heart and lung diseases,"he added."In other words,cigars are not safe alternatives to cigarettes and may be addictive.""To those individuals who may be thinking about smoking cigars,our advice is-don't. To those currently smoking cigars,quitting is the only way to eliminate completely the cancer,heart and lung disease risks,"warned Klausner.According to a National Cancer Institute press release,there haven't been any studies on the health effects on nonsmokers at cigar social events,but“... a significant body of evidence clearly demonstrates an increased lung cancer risk from secondhand smoke." According to the report,smoking three or four cigars a day______.A: increases the risk of oral cancer for non-smokersB: greatly increases the risk of oral cancer for smokersC: increases the risk of more than one cancer for non-smokers.D: greatly increases the risk of more than one cancer for smokers
共用题干第一篇A New Strategy to Overcome Breast CancerPost-menopausal（绝经后的）women who walk for an hour a day can cut their chance of breast cancer significantly,a study has suggested.The report,which followed 73,000 women for 17 years,found walking for at least seven hours a week lowered the risk of the disease.The American Cancer Society team said this was the first time reduced risk was specifically linked to walking.UK experts said it was more evidence that lifestyle influenced cancer risk.A recent poll for the charity Ramblers found a quarter of adults walk for no more than an hour a week, but being active is known to reduce the risk of a number of cancers.This study,,published in Cancer Epidemiology,Biomarkers&Prevention,followed 73,615 women out of 97,785 aged 50-74 who had been recruited by the American Cancer Society between 1992 and 1993,so it could monitor the incidence of cancer in the group.They were asked to complete questionnaires on their health and on how much time they were active and participating in activities such as walking , swimming and aerobics（有氧运动）and how much time they spent sitting,watching television or reading.They completed the same questionnaires at, two-year intervals between 1997 and 2009.Of the women,47%said walking was their only recreational activity.Those who walked for at least seven hours per week had a 14%lower risk of breast cancer compared to those who walked three or fewer hours per week.Dr.Alpa Patel,a senior epidemiologist at the American Cancer Society in Atianta Georgia,who led the study,said:"Given that more than 60% of women report some daily walking,promoting walking as a healthy leisure-time activity could be an effective strategy for increasing physical activity amongst post-menopausal women.We were pleased to find that without any other recreational activity,just walking one hour a day was associated with a lower risk of breast cancer in these women." " More strenuous（紧张的） and longer activities lowered the risk even more."Baroness Delyth Morgan,chief executive of Breast Cancer Campaign,said:"This study adds further evidence that our lifestyle choices can play a part in influencing the risk of breast cancer and even small changes incorporated into our normal day-to-day activity can make a difference."She added:"We know that the best weapon to overcoming breast cancer is the ability to stop it occurring in the first place.The challenge now is how we turn these findings into action and identify other sustainable lifestyle changes that will help us prevent breast cancer."All of the following factors relating to cancer risk were mentioned in the passage EXCEPT_______.A:regular walkingB:breathing exerciseC:recreational activityD:lifestyle choices

共用题干Screen Test1 Every year millions of women are screened with X-rays to pick up signs of breast cancer. If this happens early enough,the disease can often be treated successfully.According to a survey published last year,2 1 countries have screening programs.Nine of them,including Australia,Canada,the US and Spain, screen women under 50.2 But the medical benefits of screening these younger women are controversial,partly because the radiation brings a small risk of inducing cancer. Also,younger women must be given higher doses of X-raysbecause their breast tissue is denser.3 Researchers at the Polytechnic University of Valencia analyzed the effect of screening more than 160,000 women at 11 local clinics.After estimating the women's cumulative dose of radiation,they used two models to calculate the number of extra cancers this would cause.4 The mathematical model recommended by Britain's National Radiological Protection Board (NRPB)predicted that the screening program would cause 36 cancers per 100,000 women,18 of them fatal.The model preferred by the UN Scientific Committee on the Effects of Atomic Radiation led to a lower figure of 20 cancers.5 The researchers argue that the level of radiation-induced cancers is"not very significant"compared to the far larger number of cancers that are discovered and treated.The Valencia program,they say,detects between 300 and 450 cases of breast cancer in every 100,000 women screened.6 But they point out that the risk of women contracting cancer from radiation could be reduced by between 40 and 80 percent if screening began at 50 instead of 45,because they would be exposed to less radiation.The results of their study,they suggest,could help"optimize the technique"for breast cancer screening.7 "There is a trade-off between the diagnostic benefits of breast screening and its risks," admits Michael Clark of the NRPB.But he warns that the study should be interpreted with caution."On the basis of the current data,for every 10 cancers successfully detected and prevented there is a risk of causing one later in life.That'S why radiation exposure should be minimized in any screening program."Paragraph 4_________A:Harm Screening May Do to a Younger WomanB:Investigating the Effect of ScreeningC:Effects Predicted by Two Different ModelsD:Small Risk of Inducing Cancers From RadiationE:Treatment of CancersF:Factors That Trigger Cancers
共用题干第三篇Global Cancer Rates to Rise by 50% by 2020The number of new cancer cases worldwide is expected to increase by 50%by the year 2020.But a new report suggests that as many as a third of new cancers could be avoided by adopting healthier lifestyles and through public health action.The World Cancer Report,released by the International Agency for Research on Cancer,shows that cancer has now emerged as a major public health threat in developing countries as well as rich ones.Overall,cancer was responsible for 12%of all deaths in 2000.But in many countries more than a quarter of all deaths are caused by cancer.The report shows that 1 0 million new cancers were diagnosed globally in 2000,and that number is expected to rise to 15 million by 2020.Researchers say most of that increase will mainly be due to steadily aging populations in both developed and developing countries and current trends in smoking and other unhealthy habits."Cancer has emerged as a major public health problem in developing countries for the first time, matching its effect in industrialized（工业化的）countries , " said researcher Paul Kleihues,MD,director of IARC,in a news release."Once considered a'Western' disease,the Report highlights that more than 50 percent of the world's cancer burden,in terms of both numbers of cases and deaths,already occurs in developing countries."The risk of being diagnosed with cancer in developed countries is double that in less-developed ones.However,the risk of dying from cancer is much higher in developing countries , where 80% of cancer patients already have late-stage incurable tumors（肿瘤） at the time of diagnosis.Researchers say cancer rates have traditionally been higher in developed countries due to greater exposure to tobacco,occupational carcinogens（致癌物）,and an unhealthy Western diet and lifestyle.As less-developed countries become industrialized and more prosperous,they tend to adopt the high-fat diet and low physical activity levels typically seen in the West,which increase cancer rates. The report says that steps could be taken to reduce aboutA:50% of new cancers. B:33% of new cancers.C:12% of new cancers. D:80% of new cancers.

共用题干第一篇“Don' t Drink Alone" Gets New MeaningIn what may be bad news for bars and pubs,a European research group has found that people drinking alcohol outside of meals have a significantly higher risk of cancer in the mouth and neck than do those who drink with food.Luigino Dal Maso and his colleagues studied the drinking patterns of 1,500 patients from four cancer studies and another 3,500 adults who had never had cancer.After the researchers accounted for the amount of alcohol consumed,they found that individuals who downed a significant share of their alcohol outside of meals faced at least a 50 to 80 percent risk of cancer in the oral cavity（口腔）,pharynx（咽）,and esophagus（食管）,when compared with people who drank only at meals.Consuming alcohol without food also increased by at least 20 percent the likelihood of laryngeal cancer（喉癌）."Roughly 95 percent of cancers at these four sites traced to smoking or drinking by the study volunteers,"Dal Maso says.The discouraging news,his team reports,is that drinking with meals didn't eliminate cancer risk at any of the sites.For their new analysis,the European scientists divided people in the study into four groups,based on how many drinks they reported having in an average week.The lowest-intake group included people who averaged up to 20 drinks a week.The highest group reported downing at least 56 cups of alcohol weekly for an average of eight or more per day.Cancer risks for the mouth and neck sites rose steadily with consumption even for people who reported drinking only with meals.For instance,compared with people in the lowest group,participants who drank 21 to 34 alcohol cups a week at least doubled their cancer risk for all sites other than the larynx.If people in these consumption groups took some of those drinks outside meals,those in the higher consumption group at least quadrupled（四倍）their risk for oral cavity and esophageal cancers.People in the highest-consumption group who drank only with meals had 10 times the risk of oral cancer,7 times the risk of pharyngeal cancer,and 16 times the risk of esophageal cancer compared with those who averaged 20 or fewer drinks a week with meals.In contrast,laryngeal cancer risk in the high-in- take,with-meals-only group was only triple that in the low-intake consumers who drank with meals."Alcohol can inflame（使发炎）tissues. Over time,that inflammation can trigger cancer."Dal Maso says. He suspects that food reduced cancer risk either by partially covering digestive-tract（消化道）tissues or by taking alcohol off those tissues.He speculates that the reason laryngeal risks were dramatically lowerfor all study participants traces to the tissue's lower exposure to alcohol. Which of the four cancers has the lowest risk? A:Oral cancer.B:Laryngeal cancer.C:Pharyngeal cancerD:Esophageal cancer.

共用题干第一篇“Don' t Drink Alone" Gets New MeaningIn what may be bad news for bars and pubs,a European research group has found that people drinking alcohol outside of meals have a significantly higher risk of cancer in the mouth and neck than do those who drink with food.Luigino Dal Maso and his colleagues studied the drinking patterns of 1,500 patients from four cancer studies and another 3,500 adults who had never had cancer.After the researchers accounted for the amount of alcohol consumed,they found that individuals who downed a significant share of their alcohol outside of meals faced at least a 50 to 80 percent risk of cancer in the oral cavity（口腔）,pharynx（咽）,and esophagus（食管）,when compared with people who drank only at meals.Consuming alcohol without food also increased by at least 20 percent the likelihood of laryngeal cancer（喉癌）."Roughly 95 percent of cancers at these four sites traced to smoking or drinking by the study volunteers,"Dal Maso says.The discouraging news,his team reports,is that drinking with meals didn't eliminate cancer risk at any of the sites.For their new analysis,the European scientists divided people in the study into four groups,based on how many drinks they reported having in an average week.The lowest-intake group included people who averaged up to 20 drinks a week.The highest group reported downing at least 56 cups of alcohol weekly for an average of eight or more per day.Cancer risks for the mouth and neck sites rose steadily with consumption even for people who reported drinking only with meals.For instance,compared with people in the lowest group,participants who drank 21 to 34 alcohol cups a week at least doubled their cancer risk for all sites other than the larynx.If people in these consumption groups took some of those drinks outside meals,those in the higher consumption group at least quadrupled（四倍）their risk for oral cavity and esophageal cancers.People in the highest-consumption group who drank only with meals had 10 times the risk of oral cancer,7 times the risk of pharyngeal cancer,and 16 times the risk of esophageal cancer compared with those who averaged 20 or fewer drinks a week with meals.In contrast,laryngeal cancer risk in the high-in- take,with-meals-only group was only triple that in the low-intake consumers who drank with meals."Alcohol can inflame（使发炎）tissues. Over time,that inflammation can trigger cancer."Dal Maso says. He suspects that food reduced cancer risk either by partially covering digestive-tract（消化道）tissues or by taking alcohol off those tissues.He speculates that the reason laryngeal risks were dramatically lowerfor all study participants traces to the tissue's lower exposure to alcohol. How many drinks do the lowest-intake group average per week?A:21.B:20.C:34.D:56.
