Ever since they were first put on the market in the
early 1990s, gentically mondified (GM, 转基因) foods have
been increasingly developed and marketed in many countries in the word,mainly on the basis of their promise to end the worldwide food crisis. But can GM technology solve world hunger problems? Even if it would ,is it the best solutiorr?
Despite what it promiises,GM technology actually has not increased the production potential of any corp. In fact
Studies show that the most crown GM croo.
GM soybeans, has suffered reduced productivity. For instance, a report than analysed nearly two decades of research on mojor GM food crops shows that GM engineering has failed to significantly increase US crop production.
Something else, however, has been on the rise, While GM seeds are expensive, GM companics tell farmers that they will make good profits by saving money on pesticides(杀虫剂). On
the contrary, US government data show that GM crops in the US have produced an overall increase in pesticide use compared
to traditional crops. “ The promise was that you could use less chemicals and boost production. But nether is true,”
said Bill Christison, President of the US National Farm Coalition.
At the same time, the authors of the book World Hunger：Twelve Myths argue that there actually is more than enough
food in the world and that the hunger crisis is not caused by production, but by problems in food distribution and politics.
These indeed deserve our efforts and money. Meanwhile, the
rise in food prices results from the increased use of crops
for fuel rather than food, according to a 2008 World Bank report.
As a matter of fact ,scientists see better ways to feed the world. Another World Bank report concluded that GM crops have little to offer to the challenges of worldwide poverty and hunger, because better ways out are available, among
which “green” farming is supposed to be the first choice.
57.The author develops the second paragraph mainly . 【C】

D. Increase.
59. GM companies promise farmers that they will benefit from _________. 【B】
A. practic ing “green” farming
B. use of less chemicals
C. fair distribution of their crops
D. using more crops for fuel
60. Which of the following best describes the attitude
of the author towards GM technology?【C】

Getting rid of dirt, in the opinion of most people, is a good thing. However, there is nothing fixed about attitudes to dirt.
In the early 16th century, people thought that dirt on the skin was a means to block out disease, as medical opinion had it that washing off dirt with hot water could open up the skin and let ills in. A particular danger was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. So did the king of England in 1546.
Thus began a long time when the rich and the poor in Europe lived with dirt in a friendly way. Henry IV, King of France, was famously dirty. Upon learning that a nobleman had taken a bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.
Though the belief in the merit of dirt was long-lived, dirt has no longer been regarded as a nice neighbor ever since the 18th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War Ⅱ. Advertisements repeatedly sell the idea：clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?
Attitudes to dirt still differ hugely nowadays. Many
first-time parents nervously try to warn their children off touching dirt, which might be responsible for the spread of
disease.On the contrary, Mary Ruebush, an American immunologist(免疫学家)，encourages children to play in the
dirt to build up a strong immune system. And the latter position is gaining some ground.
64. The kings of France and England in the 16th century closed bath houses because .
A. they lived healthily in a dirty environment.
B. they thought bath houses were too dirty to stay in
C. they believed disease could be spread in public baths
D. they considered bathing as the cause of skin disease
65.Which of the following best describes Henry IV’s attitude to bathing?
A. Afraid.
B. Curious.
C. Approving.
D. Uninterested.
66. How does the passage mainly develop?
A. By providing examples.
B. By making comparisons.
C. By following the order of time.
D. By following the order of importance.
67. What is the author’s purpose in writing the passage?
A. To stress the role of dirt.
B. To introduce the history of dirt.
C. To call attention to the danger of dirt.
D. To present the change of views on dirt.

科普知识类第三篇
(2011湖南卷)C
A recent study of ancient and modern elephants has come up with the unexpected conclusion that the African elephant
is divided into two distinct (不同的) species
The discovery was made by researchers at York and Harvard universities when they were examining the genetic relationship between the ancient woolly mammoth and mastodon to modern elephants—the Asian elephant, African forest elephant and African savanna elephant
Once they obtained DNA sequences (序列) from two fossils (化石)，mammoths and mastodons the team compared them with DNA from modern elephants. They found to their amazement that modern forest and savanna elephants are as distinct from each other as Asian elephants and mammoths.
The scientists used detailed genetic analysis to prove that the African savanna elephants and the African forest elephants have been distinct species for several million years. The divergence of the two species took place around the time of the divergence of Asian elephants and woolly mammoths. This result amazed all the scientists.
There has long been debate in the scientific community that the two might be separate species but this is the most
convincing scientific evidence so far that they are indeed different species.
Previously, many naturalists believed that African savanna elephants and African forest elephants were two populations of the same species despite the elephants’ significant size differences. The savanna elephant has an average shoulder height of 3.5metres while the forest elephant has an average shoulder height of 2.5metres. The savanna elephant weighs between six and seven tons, roughly double the weight of the forest elephant. But the fact that they look so different does not necessarily mean they are different species. However, the proof lay in the analysis of the DNA.
Alfred Roca, assistant professor in the department of Animal Sciences at the University of Minois, said, “We now have to treat the forest and savanna elephants as two different units for conservation purpose. Since 1950 all African elephants have been conserved as one species. Now that we know the forest and savanna elephants are two very distinct animals, the forest elephant should become a bigger priority (优先)for conservation purpose .”
66. One of the fossils studied by the researchers is that of ________.
A. the Asian elephant
B. the forest elephant
C. the savanna elephant
D. the mastodon elephant
67. The underlined word “divergence” in paragraph
4means “________”
A. evolution
B. exhibition
C. separation
D. examination
68. The researcher’s conclusion was based on a study of the African elephant’s ____________
A. DNA
B. height
C. weight
D. population
69. What were Alfred Roca’s words mainly about?
A. The conversation of African elephants.
B. The purpose of studying African elephants
C. The way to divide African elephants into two units
D. The reason for the distinction of African elephants
70. Which of the following can be the best title for the passage?
A. Naturalist’s Belief about Elephants.
B. Amazing Experiment about Elephants
C. An Unexpected Finding about Elephants
D. A Long scientific Debate about Elephants
C 科普说明文：African elephant 有两个不同的种类
66. fossils 定位，找到第三段第一句，有两种fossils，mam
和mas，选项D
67. 文中divergence of the two species指代前文the Ase and the Afe have been distinct species, divergence与distinct 同义替换，对应选项C
68. conclusion, based on定位，找到倒数第二段最后一句lay in 与based on 同义替换，答案：A
69. AR定位，找到倒数第一段，从AR的话中，第一句for conservation purpose, 最后一句for conservation purpose确定A

However, this issue (问题) frequently causes heated debate. Some people say that classical music is associated only with old people .For example, if you look at the audience at a classical concert , the majority is over the age of fifty. Others say it is more popular than we first imagine . Many young people listen to classical music without realising .It is often used in films and advertisements. For example.a famous piece of classical music was used as the theme music for the 1990 World Cup . Not many people could have given its name , but millions enjoyed it . Also,some people point out that young people produce new music based on classical ideas: for example, it is said that rap(说唱)music was invented by a classical musician in 1912, but it is now used by young people in pop music. However, young people point to the fact that classical music has been outstripped(超越) by technology. To play a classical instrument, such as a violin, you need to study hard and practise for hours. Nowadays, you don't need to get aching arms from practising. A teenager can write and make music using a computer program in the comfort of their own bedroom. A final point to in mind is that the term "classical music" is used to refer to a great

科教科普类 1、You can remember the face, but can‘t put a name to it. Many of us have been caught in this embarrassing situation. But researchers say it is often easier to remember someone's name than what they look like. Twenty-four volunteers were shown 40 pictures of strangers, paired with random(随机的) names. They were given time to memorize the faces and names before being tested on which they thought they had seen before. The participants could remember up to 85 per cent of the names but only 73 per cent of the faces. When they were shown a different picture of the same person, the participants could recall only 64 per cent of faces, according to the study, led by the University of York. That may be because faces are only recognized visually, while names can be both spoken and written down so appear in our visual and audio memory. When people were shown famous people, they also remembered their names more accurately than their photographs. Co-author Dr Rob Jenkins, from the university's psychology department, said, "Our study suggests that, while many people may be bad at remembering names, they are likely to be even worse at remembering faces. This will surprise many people as it is against our initial understanding. Our life experiences with names and faces have misled us about how our minds work." Remembering names gets harder with age, leading to many uncomfortable moments for middle-aged people when they run into acquaintances. But to study whether names are harder to recall than faces, the researchers, whose findings are published in the Quarterly Journal of Experimental Psychology, used a “fair test” where the participants were presented with strangers’ names and faces. 1.What can we know according to the research in Paragraph 3? A.It is certain that names are harder to recall than faces. B.Remembering names is more easily than remembering faces.
一、高中英语阅读理解 1．阅读理解 City trees grow faster and die younger than trees in rural forestry, a new study finds. Over their lifetimes, then, urban trees will likely absorb less CO2 from the air thah forest trees. As we all know, the earth would be freezing or burning hot without CO2. However, CO2is a greenhouse gas, meaning it traps energy from the sun as/heat. That makes temperatures near the ground rise. Human activities, especially the widespread burning-of fossil(化石)fuels, have been sending extra greenhouse gases into the air. This has led to a rise in average temperatures across the globe. Studies had shown forests readily absorb CO2, but there hadn't been much data on whether city trees grow, die and absorb CO2at the same rate as forest trees do. So some researchers decided to find out. To figure out how quickly trees were growing, researchers tracked their diameters (the width of their trunks) between 2005 and 2014. A tree's diameter increases as it grows, just as a person's waist size increases as they gain weight. About half the weight of a tree is carbon, research has shown. Most of the rest is water. Over the nine years' tracking, the researchers found city trees absorbed four times as much carbon from the air as forest trees. However, they were twice as likely to die. So over the lifetime of each type of tree, forest trees actually absorbed more CO2. City trees grew faster because they had less competition for light from their neighbors. In a forest, trees tend to grow close together, shading their neighbors. Street trees also benefit from higher levels of nitrogen (氮)in rainwater. Nitrogen helps plants grow. Waste gases from gas-burning cars also contain nitrogen, thus enriching city air with nitrogen. Later, rainwater may wash much of it to the ground. Some street trees may also have better access to water than trees in the country because the underground water pipes can leak. （1）What can he known about CO2 from paragraph 2? A. It is one of the side effects of greenhouses. B. It greatly accelerates the process of global warming. C. It results from the widespread burning of fossil fuels. D. It prevents the earth from becoming unsuitable to live on. （2）Why did researchers track the diameters of trees? A. To know about their growth rates. B. To find out how much they weigh. C. To check whether they were healthy. D. To assess the carbon amounts in them. （3）What advantage do city trees have over forest trees? A. They are more likely to access growth promoters. B. They can enjoy more water coming from the air. C. They can enjoy more shade from neighbors. D. They are better at competing for light. （4）What will probably be talked about if the passage is continued? A. How urban trees can live longer. B. Why city living makes trees die young. C. How trees respond to dry soil conditions. D. Why faster-growing trees absorb more CO2.

The place is filled with old gravestones and gothic mausoleums(哥特式陵墓), the spirits of the dead hanging over the land like an early morning fog. Keeping watch, a few steps from the road with her skirt over the pedestal (基座), is Goldie Belle Taylor, her face weathered but otherwise in good condition. On this day, she is holding a bunch of pink roses because Goldie Belle always holds flowers. Someone makes sure of that. “And she has had fresh flowers in her hands for the last 150 years.” Karen Biery lives in Damascu Believe. five miles west of Hope Cemetery. She’s written a book based on the legend of Goldie Belle Taylor titled In 1886, at the age of two, young Goldie Belle used her hands to sop up (抹去) the left over elderberry juice from her father’s iron kettle. She died not long after from poisoning. She was the love of her dad’upset that he sold the family farm to buy the Italian made statue, which today marks her grave.

Why do the flowers keep miraculously appearing? People have tried to find out by having camped by the statue, but not even the groundskeepers have been able to catch the criminal. It’s said that a fairy arrives at Hope Cemetery looking for the grave of her birth mother. She comes across Goldie Belle’s statue. graph 2 probably refers to________. 36.

（英语）高考英语阅读理解(科普环保)解题技巧讲解及练习题(含答案) 一、高中英语阅读理解科普环保类 1．犇犇Choose the one that fits best according to the information given in the passage you have just read. While faking and fierce looks are among animals great defenses, many species know that everyone runs from a big stink (臭气) too. Vulture (秃鸳) Vultures, are street sweepers that feast on the rotting flesh of dead animals, which benefits us by ridding our highways and landscapes of animal bodies and the bacteria they might carry. When vultures feel threatened they vomit, and the smell of vomited-on dead bodies puts of most predators. Throwing up allows the vulture to fly away more quickly-and the vomit can hurt the aggressor's eyes and face. Opossum (负鼠) In some ways opossums have it easy. In order to become "dead", they don't have to fax anyone a death certificate. They just lie there with their tongues hanging out with the smell of dead flesh, sometimes for hours, effectively convincing potential predators they can find a much fresher meal elsewhere. Even if they keep getting attacked, they won't move any more than a human statue until the threat has passed. Hoatzin (磨雉) Hold your nose and meet the hoatzin, a bird of distinctions, not the least of which is that it smells like fresh cow shit. The animal mostly eats leaves and it's the only bird known to digest by fermentation, like a cow. This process is what causes its smell and has earned it the nickname the "stink bird Millipedes (千足虫) Millipedes are tricky. For starters they look wormy. Their name is deceptive, too: Their legs number about 750. Their major defense is to curl up into a ball. They, though, also release a harm eyes, and leave a horrible smell on their attackers. Sea Hare (海兔) The graceful sea hare is plain in taste in the first place, so it's not the most popular dish in the seafood chain. Nonetheless this type of sea creature has a pretty creative smell-related defense that is almost the opposite of its smelly companions on this list. The sea hare gives out a slimy, purple ink, the substance which makes food less palatable to predators. Researchers using lobsters (2-f) as model predators found that the sea blocks the lobsters receptive mechanism. In other words, the sea hare gives its attacker the equivalent of a stuffy nose so they don't know how appealing it is. （1）The sea hare defends itself from predators by ________. A. becoming plain in taste at the discovery of a predator B. giving out purple ink to make itself invisible to predators C. releasing substance to make predators unable to smell it D. giving off smelly gas to try to drive predators away
精编高中英语阅读理解题型解读大全 （一）阅读是获得更综合、更复杂、更精确信息的必要手段，考生在做阅读理解时，不仅要看懂文章的字面意思，还需要针对不同题材和体裁的篇目运用不同的方法作出正确的选择。一般来说，词汇、阅读速度和理解能力是阅读理解中三个最重要且有相互联系的因素。 阅读的方法可以使用以下几种： 1.读首段，找关键词（人名、地名、建筑、组织名、数字或but and besides howeverso therefor）。用这种阅读方法回答who、what、when、where之类的问题最为有效。 2.围绕关键词上下看一句。此种阅读方法能回答why、how之类的问题。 3.重复品味首尾段把好主题方向 （二）不同体裁文章的特点及解题技巧 1.记叙文 记叙文又可分传记类和故事类。传记类文章在阅读中时间是全文的关键，根据时间我们可以找到相关的事件，抓住文章的主要内容。故事类文章情节性较强，阅读时要注意故事中的时间、地点、人物和发生的事件，这些都是文章中的主要内容和信息，对于准确理解文章十分重要。 2.说明文 说明文是对事物的形状、性质、特征、成果或功用等进行介绍，解释或阐述的文章。把握所说明事物的特征和本质是理解说明文的关键。说明事物特征的方法很多，主要有定义法、解释法、比较法、比喻法、数字法、图表法、引用法和举例法等。 ●数字说明文 在阅读数字说明文时要特别注意文中数字的含义，从这些数字中可以找到文章的主要内容。 ●解释说明文 解释说明文着重说明事物的本质、特征和功用等。许多科普文章都属于这一类。在阅读这类文章时要学会解决what, how, why 等一类的问题。它们是文章的关键。如能带着这些问题阅读，将会更迅速抓住文章的主题。 ●比较说明文 比较说明文是通过对比方法说明问题。在阅读这类文章时要善于把握全篇陈述的基本倾向。作者在谈论一个有争议的问题时总要顾及到争议的各个方面。但是，在一般情况下，作者的陈述总要倾向于某一种观点。
七选五六大解题策略 基础差也可得高分 1. 略读文章抓大意 以最快的速度跳跃式地浏览文章的大小标题、首段、每段的首句，以及表示句、段关系的连接性词语(特别是however, but等后的内容)等重要部分，以了解文章的基本结构和内容大意。事实上，一般只需花5～10秒阅读大小标题和第一段首尾句即可。 2. 重点阅读上下句 因为正确选项必定会与上下句之间语义衔接、逻辑通顺，解题时大多只看上句，或只看下句，就可基本确定答案。 事实上，如果没有时间来得及通读或细读，或者基础不够扎实即使读也读不懂，建议通过以下技巧，也基本上可以得满分。
3. 看看结构变轻松 在解题过程中，除了每做一道有把握的题后就在7个选项中将其画掉缩小范围外，通过观察语言结构也可将选择范围大大缩小，心情变得更加轻松，一般可将7个选项缩小到2～4个选项，碰对的机率大大提高。 (1)标题结构 如果考查段落标题，先看看其他标题的语言形式，同一文章中的几个段落小标题基本上是同一语言形式。如果其他标题是名词短语，该题答案也是名词短语；如果其他标题是祈使句，该题的答案也是祈使句。 (2)句子结构 如果正确选项只是某个句子的一个部分，就要看看空后这个部分是不是句子，如果是句子，看看是否有连词，如果没有连词，要选的正确选项就应是短语或是带有连词的从句。 如：
Training for a marathon requires careful preparation and steady, gradual increases in the length of the runs. 36 , buy the best-fitting, best-built running shoes you can find. (2015新课标卷II) A. After six days B. For a good marathon runner C. Before you begin your training E. If they still feel good, you can begin running in them 解析：从句式结构上看，逗号后是祈使句，没有连词，正确答案要么是带有连词的从句，要么是一个短语，只有A、B、C、E四个选项符合，这样就缩小了选择范围；根据空前句中的preparation (准备)，和常识可知是“训练前”，故选C项。 4. 词语复现显神功

Spiders can be roughly classified according to the strategies(策略) they use for feeding. Spiders which appeared earlier in the evolutionary scale feed by waiting in a cave for food to come along before grabbing it. Following them were spiders which actively wandered looking for food and which caught it by chasing it down. The evolution of flying insects makes spiders evolve ne w ways of catching food which couldn’t be chased and so the earliest air web weavers arose. Most spiders feed on insects and other arthropods but the Whistling Spider feeds on frogs and small birds. The Golden Orb Spider also feeds on small birds. A spider periodically sheds(蜕皮;脱落) its skin so that it can grow. Immature stages are called moults. Each species has a particular number of moults that it will go through before reaching its final adult stage. Usually, once male spiders have mated, they die shortly after. But, even in death, Redback males often serve a purpose. The already pregnant Redback females always kill their lover and, in most cases, also eat them. This provides them with a small reproductive advantage. Allowing spiders to take up places around houses can be beneficial in that they catch other annoying insects such as mosquitoes and flies. Rest assured that while you might see some large spiders, and perhaps even some poisonous ones, a good rule is to look and admire but don't touch any spider you find. Even those without poison could still have a nasty bite. 1.Different families of spiders are identified themselves by ______.
