3 Travel journal*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。*语法填空Over the years, I have met some interesting people.

Im glad he changed greatly in the past two years. I clearly remember he was quite fat twoyears before. He got tired so easy that he couldnt take exercise, that made him very upset. Later, he realized unless he went on like that, he would end up achieve nothing. So he made up his minds to make a change. He went running every morning and played the basketball every afternoon. Besides, he followed a diet of more vegetables or less meat. Gradually he began to lose weight. He is now an energetic boy in good health. So when faced with problems, we should overe it with great determination and strong willpower.答案：Li Ming is a friend of mine. Im glad he changed greatly in the past two years. I clearly remember he was quite fat two years . He got tired so that he couldnt take exercise, made him very upset. Later, he realized he went on like that, he would end up nothing.

He is now an energetic boy in good health. So when faced with problems, we should overe with great determination and strong willpower.难项分析：第一处：changed前加has考查动词的时态。根据时间状语in the past two years可知，此处表示从过去开始发生的动作，并对现在造成了影响。因此，应用现在完成时。故在changed前加has。第二处：beforeago考查副词。before指从过去某刻起若干时间以前，常与完成时连用，ago指从此刻起若干时间以前，常与过去时连用。根据上下文可知，此处讲述的是过去的事情，故将before改为ago。第五处：unlessif考查连词。“he went on like that (他继续像那样)”是“he would end up . nothing”的条件，因此应用if引导条件状语从句。故将unless改为if。*
