Unit 1 Tales of the unexplained一、阅读理解Nowadays more and more people are talking about genetically modified foods ( GM foods). GM foods develop from genetically modified organisms (有机体), which have had specific changes introduced into their DNA by genetic engineering techniques. These techniques are much more precise where an organism is exposed to chemicals to create a nonspecific but stable change. For many people, the hightech production raises all kinds of environmental, ethical, health and safety problems. Particularly in countries with long farming traditions, the idea seems against nature.In fact, GM foods are already very much a part of our lives. They were first put on the market in 1996. A third of the corn and more than half the cotton grown in the U. S. last year was the product of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the US this year.The genetic genie is out of the bottle.However, like any new product entering the food chain, GM foods must be subjected to careful testing. In wealthy countries, the debate about biotech is not so fierce by the fact that they have a large number of foods to choose from, and a supply that goes beyond the needs. In developing countries desperate to feed fastgrowing and underfed populations, the matter is simpler and much more urgent: do the benefits of biotech outweigh the risks?The statistics on population growth and hunger are disturbing. Last year the worlds population reached 6 billion. The UN states that nearly 800 million people around the world are unhealthy. About 400 million women of childbearing age don t have enough iron, which means their babies are exposed to various birth defeats.As many as 100 million children suffer from vitamin A deficiency, a leading cause of blindness.How can biotech help? Genetic engineering is widely used to produce plants and animals with better nutritional values. Biotechnologists have developed genetically modified rice and they are working on other kinds of nutritionally improved crops. Biotech can also improve farming productivity in places where food shortages are caused by crop damage attributable to drought, poor soil and crop viruses.1.The passage mainly talks about_.A. the worlds food problemB. the development in biotechC. the genetically modified foods D. the way to solve food shortages2.According to the passage, GM foods_.A. will replace naturally grown foodsB. are far better than naturally grown foodsC. may help to solve the problem of poor nutritionD. can cause serious trouble in developing countries3.The underlined sentence “The genetic genie is out of the bottle.” in Paragraph 2 probablymeans that_.A.GM foods are available everywhereB. the technology in producing GM foods is advancedC. genetic technology may have uncontrollable powersD. genetic technology has e out of laboratories into markets4.Whats the writers attitude towards GM foods?A. Enthusiastic.B. Cautious.C. Disapproving.D. Unbelievable.【文章大意】本文是一篇说明文，主要介绍了转基因食品及其对人类生活的影响。1.C 【解析】主旨大意题。根据文章内容，特别是第一段中的“Nowadays more and more people are talking about genetically modified foods ( GM foods).”可知，本文主要介绍的是转基因食品。2.C 【解析】细节理解题。根据最后一段中的“Genetic engineering is widely used to produce plants and animals with better nutritional values.”可知，转基因食品有助于解决营养不良问题。4.B 【解析】观点态度题。根据第三段中的“However, like any new product entering the food chain, GM foods must be subjected to careful testing.”可知，作者认为转基因食品进入市场前需要严格的检测，由此可见作者对转基因食品的态度是谨慎的。二、词汇练习1. a cat with a lot of brown _a brown and _ creature (毛茸茸的，多毛的)2. build up ones _ mutual trust between us （力量；力气；加强）3.

think that wealth is better than health.I used to think so until one day I had read a story about Howard Joyce.He was an European billionaire who got everything he wanted.Therefore，in the last twenty years of his life，his health began to get worse and he led a miserably life.Although the best doctors called for him，he could still find no relief.I have realized that health is worth all the money in the world.If you have million of dollars but you are at poor health，you will not be able to do what you want to do.So I would like to advise you not to hurt yourself to trying to make money.Instead，take care of your body and be happy with which you do.Health is more important.【答案】There are many people / that wealth is better than health.I used to think so until one day I read a story about Howard Joyce.He was European billionaire who got everything he wanted.，in the last twenty years of his life，his health began to get worse and he led a life.Although the best doctors called for him，he could still find no relief.I have realized that health is worth all the money in the world.If you have of dollars but you are poor health，you will not be able to do what you want to do.So I would like to advise you not to hurt yourself to to make money.Instead，take care of your body and be happy with you do.Health is more important.第一处：think前面加who或think改为thinking。考查定语从句或现在分词。分析该句结构可知，该句为定语从句，先行词为many people，故用who引导该定语从句；因many people和think为主动关系，故也可以用现在分词thinking作many people的后置定语。第二处：删除had。考查时态。根据该句中的“used to”和“until one day”可知，该句陈述的是过去发生的事情，故用一般过去时。第三处：ana。考查冠词。European的读音以辅音音素开头，故用a。第四处：ThereforeHowever。考查副词。上文说他是一位欧洲亿万富翁，得到了他想要的一切，该句说在他生命里的最后二十年，他的健康状况变得越来越糟。上下文为转折关系，故用However。第五处：miserablymiserable。考查形容词。life为名词，故应用形容词miserable修饰。第六处：called前面加were。考查主谓一致、时态和语态。主语the best doctors为复数且和动词call之间为动宾关系，故用被动语态；这里讲述的是过去发生的事情，故用were。第七处：millionmillions。考查固定搭配。millions of为固定搭配，表示“许多”。第八处：atin。考查介词。in poor health为固定搭配，意为“身体不好”。第九处：tryingtry。考查动词不定式。此处是动词不定式表目的，故to后应用动词原形try。第十处：whichwhat。考查宾语从句。分析该句结构可知，with后接宾语从句，连接词在从句中作do的宾语，故用what。
