GM foods develop from geically modified anisms (有机体 ), which have had specific changes introduced into their DNA by geic engineering techniques. These techniques are much more precise where an anism is exposed to chemicals to create a non173。 specific but stable change. For many people, the high173。 tech 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 geically modified crops will be planted in the US this year. The geic 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 fast173。 growing 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 world39。 s population reached 6 billion. The UN states that nearly 800 million people around the world are unhealthy. About 400 million women of childbearing age don39。 t have enough iron, which means their babies are exposed to various birth many as 100 million children suffer from vitamin A deficiency, a leading cause of blindness. How can biotech help? Geic engineering is widely used to produce plants and animals with better nutritional values. Biotechnologists have developed geically 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. 32. The passage mainly talks about________. A. the world39。 s food problem B. the development in biotech C. the geically modified foods D. the way to solve food shortages 33. According to the passage, GM foods________. A. will replace naturally grown foods B. are far better than naturally grown foods C. may help to solve the problem of poor nutrition D. can cause serious trouble in developing countries 34. The underlined sentence “The geic genie is out of the bottle.” in Paragraph 2 probably means that________. A. GM foods are available everywhere B. the technology in producing GM foods is advanced C. geic technology may have uncontrollable powers D. geic technology has e out of laboratories into markets 35. What39。 s the writer39。 s attitude towards GM foods? A. Enthusiastic. B. Cautious. C. Disapproving. D. Unbelievable. 【考点】健康保健 【试题解析】本文主要介绍了转基因食品。 1．通读全文可知本文主要介绍了转基因食品。 故选项 C正确。 考点定位：考查主旨大意 2．根据最后一段 Geic engineering is widely used to produce plants and animals with better nutritional values．一句可知转基因食品有助于解决营养不良问题，可知答案选 C。 考点定位：考查细节理解 3．本段主要介绍了转基因食品的生产及进入市场流通。 故答案 D正确。 考点定位：考查推 理判断 4．作者详细叙述了转基因食品的特点，及对人类的益处。 但是根据文中 However, like any new product entering the food chain, GM foods must be subjected to careful testing一句可知作者对于转基因食品持谨慎态度，故答案 B正确。 【答案】 3235： CCDB 第二节（共 5小题；每小题 2分，满分 10分） 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。 选项中有两项为多余选项。 With the summer holiday just around the corner, it seems like everybody is busy planning their vacations.
