问题 Text3 Genetically engineered crops are safe for humans and animals to eat and have not caused increases in cancer,obesity,gastrointestinal illnesses,kidney disease,autism or allergies,an exhaustive report from the National Academies of Science released Tuesday found.Overall,genetically engineered（GE）crops saved farmers in the United States money but didn't appear to increase crop yields.They have lowered pest populations in some areas,especially in the Midwest but increased the number of herbicide-resistant weeds in others.There's also no evidence that GE crops have affected the population of monarch butterflies,the report said.To gauge whether foods made from genetically modified crops were safe for human consumption,the committee compared disease reports from the United States and Canada,where such crops have been consumed since the mid-1990s,and those in the United Kingdom and westem Europe,where they are not widely eaten.No long-term pattem ofincrease in specific health problems after the introduction of GE foods in the 1990s in the United States and Canada was found.There was no correlation between obesity or Type n diabetes and the consumption of GE foods.Celiac disease,which makes humans intolerant of gluten,increased in both populations.Patterns in the increase in autism spectrum disorder in children were similar in both the United Kingdom and the United States,the committee reported.Overall the report concluded that there were no differences in terms ofa higher risk to human health between foods made from GE crops and those made from conventionally-bred crops.Food&Water Watch,a government accountability group in Washington D.C.,said the committee's ties to the biotech industry and other corporations create conflicts ofinterest and raise questions about the independence ofits work."Critics have long been marginalized,"said Wenonah Hauter,the group's executive director.A significant portion of American consumers are concerned about the safety or other effects of foods made with genetically modified crops,often called GMOs for genetically modified orgarusms.A survey released last year by the NPD Group,a market research firm,found that 57%ofAmericans were concemed that genetically modified foods posed a health hazard.The food industry has taken notice.In 2015,Progressive Grocer,a trade publication,reported that total U.S.sales of food and beverage products labeled"non-GMO"reached$10 billion during 2014.The National Academies report will likely not sway these consumers,said Phil Lempert,a Los Angeles-based food industry analyst."It's an emotional issue,it's not a science issue,"he said.35.Which of the following would be the best title of the text?A.Academies of Science Finds GMOs Unharmful to Human HealthB.Public Concem about GMOs Is Not Reduced with Science ReportC.The Independence of U.S.Science Report Is QuestionedD.Americans Prefer the Non-GMO for Its Healthier Element
选项 A.Academies of Science Finds GMOs Unharmful to Human Health
B.Public Concem about GMOs Is Not Reduced with Science Report
C.The Independence of U.S.Science Report Is Questioned
D.Americans Prefer the Non-GMO for Its Healthier Element
答案 A
解析 主旨大意题。本文主要内容是提出一份美国国家科学院发表的报告，证明转基因食品无害，同时也表明一些反对的观点以及消费者的普遍认识。故A项正确。【干扰排除】B项“公众对于转基因作物的担忧不会因为科学报告的发表而有所减少”原文中没有提到；C项“美国科学报告的独立性受到质疑”只是原文中出现的一个细节，不能概括文章主旨；D项“非转基因食品因为其更健康的成分更受到美国人的喜爱”，原文中有提到，但不是本文的重点，不能作标题。
