3 Travel journal ***閱讀理解 Nowadays more and more people are talking about genetically modified foods ( GM foods). GM foods develop from genetically modified organisms (有機(jī)體), 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 problem B. the development in biotech C. the genetically modified foods D. the way to solve food shortages 2.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 3.The underlined sentence “The genetic 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. genetic technology may have uncontrollable powers D. genetic technology has e out of laboratories into markets 4.Whats the writers attitude towards GM foods? A. Enthusiastic. B. Cautious. C. Disapproving. D. Unbelievable. 【文章大意】本文是一篇說(shuō)明文，主要介紹了轉(zhuǎn)基因食品及其對(duì)人類生活的影響。 1.C 【解析】主旨大意題。根據(jù)文章內(nèi)容，特別是第一段中的“Nowadays more and more people are talking about genetically modified foods ( GM foods).”可知，本文主要介紹的是轉(zhuǎn)基因食品。 2.C 【解析】細(xì)節(jié)理解題。根據(jù)最后一段中的“Genetic engineering is widely used to produce plants and animals with better nutritional values.”可知，轉(zhuǎn)基因食品有助于解決營(yíng)養(yǎng)不良問(wèn)題。 4.B 【解析】觀點(diǎn)態(tài)度題。根據(jù)第三段中的“However, like any new product entering the food chain, GM foods must be subjected to careful testing.”可知，作者認(rèn)為轉(zhuǎn)基因食品進(jìn)入市場(chǎng)前需要嚴(yán)格的檢測(cè)，由此可見(jiàn)作者對(duì)轉(zhuǎn)基因食品的態(tài)度是謹(jǐn)慎的。 ***語(yǔ)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 two years 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.

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. So he made up his to make a change. He went running every morning and played basketball every afternoon. Besides, he followed a diet of more vegetables 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 with great determination and strong willpower. 難項(xiàng)分析： 第一處：changed前加has　考查動(dòng)詞的時(shí)態(tài)。根據(jù)時(shí)間狀語(yǔ)in the past two years可知，此處表示從過(guò)去開(kāi)始發(fā)生的動(dòng)作，并對(duì)現(xiàn)在造成了影響。因此，應(yīng)用現(xiàn)在完成時(shí)。故在changed前加has。 第二處：before→ago　考查副詞。before指從過(guò)去某刻起若干時(shí)間以前，常與完成時(shí)連用，ago指從此刻起若干時(shí)間以前，常與過(guò)去時(shí)連用。根據(jù)上下文可知，此處講述的是過(guò)去的事情，故將before改為ago。 第五處：unless→if　考查連詞。“he went on like that (他繼續(xù)像那樣)”是“he would end up ... nothing”的條件，因此應(yīng)用if引導(dǎo)條件狀語(yǔ)從句。故將unless改為if。 ***
