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。B(2018河北石家庄高中毕业班一模)Few people are aware that Waterloo Bridge, crossed by thousands of daily muters(通勤者) and celebrated as a London landmark, was mainly built by a female workforce.There are no written or photographic records of the women who built the bridge since the construction pany that built it closed in the 1980s and with it went all the records. Whats left is anecdotal evidence, kept alive by the tourist boat captains who have called it the Ladies Bridge.During the Second World War, with the majority of the active male labor force away at the front, women increasingly took on traditionally male roles. By 1944, 25，000 women were working in the construction industry, carrying out backbreaking tasks. These women were permitted to carry out this exhausting and dangerous work on the basis that it would only be temporary and that their pay would be lower than that of men. So the trend in women working in construction and engineering did not continue after the war.September sees a series of events celebrating the unknown work of the large female workforce. Musician Claudia Molitor has created a 45minute musical entitled “the Singing Bridge”， which runs at Somerset House from 9 to 25 September. In late September, the “Light up the Ladies Bridge” event sees the National Theatres fly tower lit up by large scale photographic projections(投影) of female construction workers working in construction during World War .Lets all celebrate the women who have helped to build the cities in which we live.【解题导语】本文是一篇说明文。介绍了英国滑铁卢桥的历史、建造人、纪念活动等。1Why do few people know about the builders of Waterloo Bridge?AThe records of their work have been lost.BFemale workers received little attention.CThe construction took place long ago.DFew people know about the bridge.A解析：细节理解题。根据第二段的第一句可知，自从20世纪80年代建造该桥的建筑公司倒闭以来，就没有妇女建造该桥的文字或照片记录了，所有的记录随着公司的倒闭都丢失了，故A项正确。2Why did London women do the construction work?AIt was a tradition in London.BThey wanted to get a steady job.CThe pany offered them better pay.DMost men had gone to the battlefield.D解析：细节理解题。根据第三段的第一句可知，由于二战期间大部分男子上前线参战，妇女便不得不充当起了男子的角色，故D项正确。3Whats the fourth paragraph mainly about?AThe influence of the bridge on art.BA musicians contribution to the bridge.CThe events in honor of the bridge builders.DWomens work during the Second World War.C解析：段落大意题。通读第四段可知，该段第一句为该段主题句，该段主要介绍了在九月份举行的一系列纪念建桥者的活动，故C项正确。4Which can be the best title for the text?AFemale Workers on the Rise BA Hidden Treasure in LondonCA New London LandmarkDThe Story Behind the Ladies BridgeD解析：标题归纳题。通读全文可知，本文主要介绍了英国滑铁卢桥的历史、建造人、纪念活动等，重点介绍了该桥被称为“女士桥”的原因和其背后的故事，故D项最适合作本文标题。三、七选五When high temperatures are around the country，some things also go up.Here are four things expected to rise along with our desire to stay indoors and beat the heat.1Sales of goods that keep you coolMalls are high on the list of places where people often go for free air conditioning outside home in summer._1_ Goods related to keeping cool，like air conditioners，fans or sun care items，are very popular.2_2_Pests like stink bugs(椿象)grow fast during summer heat waves，and many agriculture experts are expecting a repeat of last years outbreak that harmed fruit and crops，particularly on the East Coast.3Energy bills_3_ With all those air conditioners and fans working，it makes sense that energy bills will be higher than average._4_ “Not only are people going to have extremely high energy bills for July，it will also put increased stress on power plants，and were going to see more air pollution because of it，” says Angela Fritz.4ViolenceHeat waves may cause violence，right? “Not necessarily，”says Richard Larrick，a researcher.He took a unique look at the relationship between violence and heat through baseball.Larrick and his research team examined 57,294 Major League Baseball games taking place between 1962 and 2017 and found that while heat may increase violence，there always has to be a motive.“_5_ Instead，heat affects a specific form of violence，” he said.AAir pollutionBPest populationCRising heat is the expected response in any summer.DHeat does not directly lead to more violence in general.EMore and more people are worried about their expenses.FAs more energy is used，air quality problems may occur.GSo its not a surprise that some sales jump during heat waves.【解题导语】本文介绍了伴随高温天气会出现的一些事件。1G空前一句提到购物中心是夏天人们外出经常去的地方之一，空后一句提到与制冷有关的商品，如空调、风扇等都很受欢迎，结合本段小标题可知，G项“因此一些(制冷商品的)销售量在酷暑期猛增就不足为奇了”与此处匹配。2B根据空处所在位置可知，空处为本段小标题。根据空后的“Pests like stink bugs(椿象)grow fast during summer heat waves”可知，本段主要是说害虫的数量在酷暑期也会快速增长，故B项与此处匹配。3E根据段落小标题Energy bills可知，本段和费用有关，空后又提到(电)风扇和空调的运行会使能源费用高于平均水平，故空处应讲人们对高温天气下使用这些电器的花费的担忧，所以E项符合语境。4F上文提到能源费用增加，下文提到由此会造成更多的空气污染。由此可推知，F项“随着更多的能源被消耗，空气质量问题可能会出现”与此处匹配。5D根据空后一句可知，高温影响一种特定形式的暴力，且由“Instead”可知，空处与下文呈转折关系，再结合上文的“Not necessarily”可知，D项“总的来说，高温不会直接导致更多的暴力”与此处匹配。
