Background Information Directions ask Ss to work in groups to find related background information and make presentation in class 1 Gene Technology Gene technology genetic engineering genetic modification all mean the same thing They re all one type of modern biotechnology Until the 1950s traditional biotechnology was a pretty imprecise and time consuming affair Then scientists discovered that the DNA wrapped up inside the cells of all living things is like a blueprint that is passed from one generation to another Modern biotechnology took off when scientists found that all living things use the same genetic message code Gene technology is just one branch of modern biotechnology used in an attempt to control or modify genes or most significantly move them between two unrelated species this is what s called recombinant DNA technology 2 Genetically Modified Foods GM Foods made from crops that have been given specific traits through genetic engineering plant products including soybean corn canola and cotton seed oil but they are now also experimenting with animals controversial 3 Golden Rice genetically engineered to produce beta carotene a substance which the body can convert to Vitamin A quickly heralded as a miracle cure for vitamin A deficiency VAD a condition which afflicts millions of people in developing countries especially children and pregnant women 4 Franken food Opponents of genetically modified food often refer to it as Franken food after Mary Shelley s character Frankenstein and the monster he creates in her novel of the same name The term was coined in 1992 by Paul Lewis an English professor at Boston College who used the word in a letter he wrote to the New York Times in response to the decision of the US Food and Drug Administration to allow companies to market genetically modified food While reading I Global Reading Activity one Text Structure group work Directions work in groups and skim the text quickly and try to find out the

Particularly in countries with long agrarian traditions the idea seems against nature Para 1 Especially in the countries which have long traditions in agriculture the idea of genetically modified food seems to violate the law of nature 特别是在农业传统悠久的国家 这一理念似乎有悖自然 Note that with long agrarian traditions is used as a post modifier to modify countries e g China is an ancient civilization with long history 2 In wealthy countries the debate about biotech is tempered by the fact that we have a rich array of foods to choose from and a supply that far exceeds our needs Para 3 In rich countries where there is a rich choice of foods and the supply goes far beyond what is necessary the debate about biotechnology is moderated or softened 在富裕的国家里 关于生物技术的争论相对缓和是由于有大量丰富的食品可供选择 而 且供应远远超过需求 Note In this sentence there are two that clauses The first one is an appositive clause while the second one is an attributive clause 11 3 In developing countries desperate to feed fast growing and underfed populations the issue is simpler and much more urgent Para 3 In developing countries extremely eager to feed their people who are increasing rapidly and who have had too little food the problem is simpler and much more pressing 而在发展中国家 其迅速增长又吃不饱的人口迫切需要 养活 问题就更为简单 也更加紧迫 4 food shortages are caused by crop damage attributed to pests drought poor soil and crop viruses Para 6 food shortages result from loss of crops as a result of pests drought poor soil and crop viruses 因虫害 干旱 土壤贫瘠和作物病毒而作物减产以致食物匮乏 Note in the sentence attributed is a past participle used to modify crop damage and the structure can be changed into crop damage that is attributed to pests drought 5 Biotech is not a panacea but it does promise to transform agriculture in many developing countries Para 9 Biotechnology is not a solution to all the problems but it really is expected to change agriculture in many developing countries 生物技术虽不是万灵药 但它确实有望革新许多发展中国家的农业 Note does promise 是动词强调式 用于加强语气 e g That s exactly what she did say You do look nice to day Post reading Summary of the Text Will genetically modified foods feed the world In fact 1 are working on nutritionally improved crops and improving farming 2 to solve the problems of 3 growth hunger declining arable 4 and undernourishment However 5 in developing countries and biotech s 6 problems prevent genetic research on food from being 7 Though more biotech research is being carried out in developing countries there is still a need for better 8 between government agencies and 9 biotech firms Biotech is not the whole answer but it does promise to transform 10 in many developing countries Homework 1 Review the new words and expressions 2 Finish the relevant exercises III Exercises Detailed Reading 1 A 2 B 3 D 4 D 5 B 12 Vocabulary 1 1 exceed 2
