共用题干Food FrightExperiments under way in several labs aim to create beneficial types of genetically modified(GM)foods,including starchier potatoes and caffeine-free coffee beans.Genetic engineers are even trying to transfer genes from a cold-water fish to make a frost-resistant tomato.A low-sugar GM strawberry now in the works might one day allow people with health problems such as diabetes to enjoy the little delicious red fruits again.GM beans and grains supercharged with protein might help people at risk of developing kwashiorkor. Kwashiorkor,a disease caused by severe lack of protein,is common in parts of the world where there are severe food shortages.Commenting on GM foods,Jonathon Jones,a British researcher,said,"The future benefits will be enormous,and the best is yet to come."To some people,GM foods are no different from unmodified foods."A tomato is a tomato," said Brian Sansoni,an American food manufacturer.Critics of GM foods challenge Sansoni's opinion.They worry about the harm that GM crops might do to people,other animals,and plants.In a recent lab study conducted at Cornell University,scientists tested pollen made by Bt corn,which makes up one-fourth of the U .S.corn crop.The scientist sprinkled the pollen onto milkweed,a plant that makes a milky juice and is the only known food source of the monarch but-terfly caterpillar. Within four days of munching on the milkweed leaves,almost half of a test group of caterpillars had died."Monarchs are considered to be a flagship species for conservation,"said Cornell researcher Linda Raynor."This is a warning bell."Some insects that are not killed by GM foods might find themselves made stronger. How so? The insecticides used to protect most of today's crops are sprayed on the crops when needed and decay quickly in the environment.But GM plants produce a continuous level of insecticide.Insect species feeding on those crops may develop resistance to the plants and could do so in a hurry, say the critics.Insects may also develop a resistance to the insecticide Bt.At the forum on GM food held last year in Canada,GM crops that have been made resistant to the herbicide might crossbreed with wild plants,creating"superweeds"that could take over whole fields.So where do you stand?Should GM foods be banned in the United States,as they are in parts of Europe?Or do their benefits outweigh any of the risks they might carry? What happens to those insects when not killed by the spray of insecticide?A: They may lose their ability to produce offspring.B: They may have a higher ability to adapt to the environment.C: They move to other fields free from insecticide.D: They never eat again those plants containing insecticide.

Passage TwoGenerationsof Americans have been brought up to believe that a good breakfast is essentialto one′s life.Eating breakfast at the start of the day,we have been told,and told again,is as necessary asputting gasoline in the family car before starting a trip.But for many people,the thought of food as the first thing in the morning is never a pleasure Sodespite all the efforts,they still take no breakfast.Between 1977 and 1983,the latest year for which figures could beobtained,the number of people who didn′t have breakfast increased by 33%from8.8 million to 11.7 million--according to the Chicago-based Market ResearchCorporation of America.For those who dislike eating breakfast,however,thereis some good news.Several studies in the last few years have shown that,for adults especially,there may be nothing wrong with omitting breakfast."Going without breakfast does not affect work,"said Arnold E.Bender,former professor of nutrition at Queen Elizabeth College in London,"nor does giving people breakfast improve work."Scientific evidence linkingbreakfast to better health or better work is surprisingly inadequate(不充分),and most of the recent work involves children,not adults."The literature,"says one researcher,Dr.Earnest Polite at theUniversity of Texas,"is poor."What does the word"literature"in the last sentence?refer to?A.Modem American literature.B.Any printed materials.C.Written works on a subject.D.Stories,poems and plays.

共用题干Losing WeightGirls as young as 10 years old are dieting and in danger of developing unhealthy attitudes about weight,body image and food,a group of Toronto researchers reported Tuesday.Their study of 2,279 girls aged 10 to 14 showed that while the vast majority had healthy weights,nearly a third felt they were overweight and were trying to lose pounds. Even at the tender age of 10,nearly 32 percent of girls felt"too fat"and 3 1 percent said they were trying to diet.McVey,a researcher at the Hospital for Sick Children in Toronto,and her colleagues analyzed data collected in a number of surveys of southern Ontario school girls between 1993 and 2003,reporting their findings in Tuesday's issue of the Canadian Medical Association Journal.Nearly 80 percent of the girls had a healthy body weight and only 7.2 percent were considered overweight using standard weight-to-height ratios.Most researchers suggest the rate of overweight children in this country is several times higher than that figure.Nearly 30 percent of the girls reported they were currently trying to lose weight,though few admitted to dangerous behavior such as self-induced vomiting.Still,a test that measured attitudes towards eating showed 10.5 percent of survey participants were already at risk of developing an eating disorder."We're not talking about kids who've been prescribed a diet because they're above average weight or overweight. We're talking about children who are within a healthy weight range.And they have taken it upon themselves to diet to lose weight,"McVey said,acknowledging she found the rates disturbing. She said striking a balance between healthy weights and healthy attitudes towards food and body image is a complex task,with no easy solutions. What kind of institution does the lead researcher work with?A: A school.B: A hospital.C: An association.D: A charity.
