194. Generations of Americans have been brought up to believe that a good breakfast is one of life’s essentials. Eating breakfasts at the start of the day, we have all been told, and told again, is as necessary as putting gasoline in the family car before starting a trip. But for many people the thought of food first thing in the morning is by no means a pleasure. So despite all the efforts, they still take no breakfast. Between 1977 and 1983, the latest year for which figures are available, the number of people who didn’t have breakfast increased by 33 percent from 8.8 million to 11.7 million—according to the Chicago-based Market Research Corporation of America. For those who feel pain of guilt about not eating breakfast, however, there is some good news. Several studies in the last few years indicate that, for adults especially, there may be nothing wrong with omitting breakfast. “Going without breakfast does not affect performance,” said Amold Bender, former professor of nutrition at Queen College in London, “nor does giving people breakfast improve performance.” Scientific evidence linking breakfast to better health or better performance is surprisingly inadequate, and most of the recent work involves children, not adults. “The literature,” says one researcher, Dr. Emesto Polite at the University of Texas, “is poor.” [共5题](1) The latest year for which figures could be obtained is ________.(A) the year the author wrote the article(B) any year between 1977 and 1983(C) 1977(D) 1983(2) For those who do not take breakfast, the good news is that ________.(A) several studies have been done in the past few years(B) the omission of breakfast does no harm to one’s health(C) adults have especially made studies in this field(D) eating little in the morning is good for health(3) “…, nor does giving people breakfast improve performance” (in Para.3 ) means ________.(A) anyone without breakfast does improve his performance(B) not giving people breakfast improves performance(C) having breakfast does not improve performance, either(D) people having breakfast do improve their performances, too(4) The word “literature” in the last sentence refers to ________.(A) stories, poems, plays, etc.(B) written works on a particular subject(C) any printed material(D) the modern literature of America(5) What is implied but NOT stated by the author is that ________.(A) not eating breakfast might affect the health of children(B) Dr. Polite is engaged in research work at an institution of higher learning(C) breakfast does not affect performance(D) Professor Bender once taught college courses in nutrition in London

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.

共用题干Cigars Instead?Smoking one or two cigars a day doubles the risk of cancers of the lip,tongue,mouth,and throat,according to a government study.Daily cigars also increase the risk of lung cancer and cancer of the esophagus,and increase the risk of cancer of the larynx(voice box)sixfold,say researchers at the National Cancer Institu- te in Bethesda,Maryland. 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." What is the doctors' advice to those cigar-smokers?A: To give it up completely.B: To give up part of it.C: Not to think about it any more.D: To cure the diseases first.

Some skeptics believe that there will be a shortage of food if animals are not eaten.In fact,the opposite is true.More than 80% of the corn and 95% of the oats grown in the U.S.are fed to livestock.The world's cattle alone consume enough food to equal the caloric needs of 8.7 billion people,more than the entire human population.One half of the water used in the Unites States also goes to livestock;250 gallons of water produces only 1 lb.(磅)of beef.If people eat less meat and more plants,the amount of available food will increase。 Many people become vegetarians because they feel that eating animals is unethical.90% of these animals are raised in confinement.Chickens and other birds have only about half a square foot of space each,and since they are raised so close together,a lot of blade is used to cut off their beaks to prevent them from pecking each other to death.Likewise,pigs that are repressed will bite each other's tails,so both their teeth and tails are removed as soon as they are born. Eating animals is hazardous in numerous ways.Even a slight reduction in meat intake is better than nothing at all.Consuming less meat is beneficial to the health of animals,the health of people,and to the health of the world.Why does the author say reducing the amount of meat in one's diet is environmentally beneficial?A:People who eat meat usually have weaker immune systems compared to those of vegetarians.B:A lot of food and water are consumed in order to raise livestock.C:90% of animals are raised in confinement.D:Raising Animals causes most of the destruction of the nature.

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Geology and Health1. The importance of particular metals in the human diet has been realized within the past few decades,and the idea that geology might be related to health has been recognized for a number of elements such as iodine,zinc and selenium. For example,soils with low iodine contents produce crops,and animals deficient in iodine.A lack of iodine in the human diet leads to some serious diseases.2.The ultimate source of metals within the human body is rocks,which weather into soil.gaining or losing some of their chemical constituents. The crops we eat selectively remove from the soil the elements that they require for growth .The water we drink contains trace elements leached from rock and soil. Thus the geology and geochemistry of the environments have effects on the chemis-try and health of plants,animals and people.3. So far there is no data to suggest that people living on metal-rich soils experience a potential health hazard. The levels of metals within naturally contaminated soils are generally not high enough to cause serious health problems.Living on metal-rich soils does not represent a health risk unless large quantities of soil are digested or metal-rich dust is inhaled.However,small chil-dren are particularly exposed to metal-rich topsoil in playgrounds and gardens. They are also the most likely ones to eat potentially dangerous metal-rich soil.4. Heavy metals are persistent:they do not break down to other chemicals in the environment. Industrially polluted sites usually undergo intensive clean-up and rehabilitation because heavy metals are a health concern once they enter the food chain. Some trace metals are alleged to cause cancer and are also known to cause poisoning.5.In contrast,naturally contaminated soils have not been subject to risk assessment studies and rehabilitation measures,despite the fact that they frequently possess metal concentrations well above those of such polluted by humans and above environmental quality criteria.6.There is a vital need to understand the potential risks and long-term health effects of living on naturally contaminated soils.Future environmental investigations of naturally polluted soils should concentrate on the potential pathways of metals into the food chain and human body.Geologists should be part of such studies as they can provide the essential background information on rock and soil chemistry as well as the chemical forms of heavy metal pollution.Some diseases is connected with deficiency of_______.A:.industrially polluted soilsB: rock and soil chemistryC:.naturally polluted soilsD: the pathways of metals into the food chainE: the element of iodineF: the persistence of heavy metals

共用题干第一篇The Relationship between IQ and Being a VegetarianA Southampton University team found that people who were vegetarians (素食主义者)by 30 had recor-ded five IQ points higher on average at the age of]U.Researchers said it could explain why people with a higher IQ were healthier as a vegetarian diet was linked to lower heart disease and obesity(肥胖)rates.The study of 8,179 people was reported in the british Medical Journal.Twenty years after the IQ tests were carried out in 1970,366 of the participants said they were vegetarians一 although more than 100 reported eating either fish or chicken.Men who were vegetarians had an IQ score of 106,compared with 101 for non-vegetarians;while female vegetarians averaged 104,compared with 99 for non-vegetarians.There was no difference in the IQ scores between strict vegetarians and those who said they were vegetarians but reported eating fish or chicken.Researchers said the findings were partly related to better education and higher class,but it remained statistically significant after adjusting for these factors.Vegetarians were more likely to be female,to be of higher social class and to have higher academic or vocational qualifications than non-vegetarians.However,these differenIces were not reflected in their annual income,which was similar to that of non-vegetarians.Lead researcher Catharine Gale said,"The findings that children with greater intelligence are more likely to report being vegetarians as adults,together with the evidence on the potential benefits of a vegetarian diet on heart health,may help to explain why a higher IQ in childhood or adolescence is linked with a reduced risk ofcoronary heart disease in adult life."But Dr Frankie Phillips of the British Dietetic Association said, "It is like the chicken and egg."Dopcople become vegetarians because they have avery high IQ or is it just that they are clever enough to bemore aware of health issues?It was found in the research that______________.A:most of the participants became vegetarians 20 years after the IQ tests were carried out B:vegetarians who ate fish or chicken were of similar intelligence with strict vegetariansC:female vegetarians were more likely to have higher annual income than non-vegetariansD:vegetarians were more likely to have higher annual income than non-vegetarians
