2019-2020年高考英语北师大版一轮复习课时作业：语言朋友（33）Organic food, once considered something that only health fanatics desired, is now a regular feature at most supermarkets.And that has created a bit of a dilemma.On the one hand, you have a conventionally grown apple.On the other, you have one thats organic.Both apples are firm, shiny and red.Both provide vitamins and fiber, and both are free of fat, sodium and cholesterol.Conventionally grown food generally costs less, but is organic food a better choice? The advantages claimed for such foods over conventionally grown and sold food products are now being debated on a large scale.Supporters of organic foodsa term whose meaning varies greatlyare frequently telling the world that such products are safer and more nutritious than others.The growing interest of consumers in the safety and nutritional quality of daily foods is a wele development.However, much of this interest has been aroused by sweeping claims that the conventional food supply is unsafe or inadequate in meeting nutritional needs.Almost daily, the public is surrounded by claims for “noaging” diets, new vitamins and other wonder foods.There are numerous unsubstantiated reports that natural vitamins are superior to manmade ones, that fertilized eggs are nutritionally superior to unfertilized eggs, that untreated grains are better than those treated with insect spray and the like.Although most of these claims are not supported by scientific evidence, large amounts of written material about the benefits of organic foods makes it difficult for people to separate fact from fiction.As a result, claims that eating a diet consisting of organically grown foods prevents or cures disease or provides other benefits to health have bee widely advertised and form the basis for peoples opinion.One thing that most organically grown food products seem to have in mon is that they cost more than conventionally grown foods.But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods.So there is real cause for concern if consumers, particularly those with limited ines, distrust the conventional food supply and buy only expensive organic foods instead.解题导语：近年来，人们争相吃有机食品，但作者认为有机食品花费大且不一定比传统食品更有营养价值。1According to Paragraph 2, which of the following statements about organic food is true?AIt has no agreed definition.BIt is popular among producers.CIt is accepted by most nutritionists.DIt hasnt been used until recent years.解析：细节理解题。根据第二段的内容可知对于有机食品没有统一的界定，故选A。答案：A2In Paragraph 4, treated grains are examples of _.Aorganic foodBconventionally grown foodCexpensive foodDhealthier food解析：细节理解题。根据“that untreated grains are better than those treated with insect spray.”可知用药喷洒的庄稼是传统的粮食作物，故选B。答案：B3It can be inferred from the passage that _Aorganic foods are actually less nutritious than conventionally grown foodsBpeople cannot separate fact from fiction because of the TV advertisementsCorganic foods cost more but are not necessarily better than conventionally grown foodsDmost doctors believe that organic foods prevent disease or provide other benefits to health解析：推理判断题。根据最后两段内容可以推知，有机食品花费大、价格高，且不一定比传统的食物更好，故选C。答案：C4According to the passage, many consumers are attracted by organic foods because they _Ahave carefully researched the productsBvalue food safety and nutritionCexpect to save some moneyDwant to try something new解析：细节理解题。根据最后一段“But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods.”可知是因为那些消费者太看重食物的安全与营养，故选B。答案：B5What is the authors attitude toward the claims of organic foods?AEnthusiastic.BSupportive.CUninterested.
