第2部分：阅读判断（第16～22题，每题1分，共7分）(*_*)下面的短文后列出了7个句子，请根据短文的内容对每个句子做出判断：如果该句提供的是正确信息，请选择A；如果该句提供的是错误信息，请选择B；如果该句的信息文中没有提及，请选择C.(*_*)Radiocarbon Dating(*_*) Nowadays scientists can answer many questions about the past through a technique called radiocarbon（放射性碳），or carbon-14，dating. One key to understanding how and by something happened is to discover when it happened.(*_*)Radiocarbon dating was developed in the late 1940s by physicist Willard F. Libby at he University of Chicago. An atom of ordinary carbon，called carbon-12，has six protons（中子）and six neutrons（质子）in its nucleus. Carbon-14，or C-14，is a radioactive，unstable form of carbon that has two extra neutrons（原子核）。

It returns to a more stable form of carbon through a process called decay（衰减）。

This process involves the loss of he extra neutrons and energy from the nucleus.(*_*)In Libby's radiocarbon dating technique，the weak radioactive emissions（放射）from his decay process are counted by instruments such as a radiation detector and counter. he decay rate is used to determine the proportion of C-14 atoms in the sample being dated.(*_*)Carbon-14 is produced in the Earth's atmosphere when nitrogen（氮）-14，or N-14，interacts with cosmic rays（宇宙射线）。

Scientists believe since the Earth was formed，the mount of nitrogen in the atmosphere has remained constant. Consequently，C-14 formation is thought to occur at a constant rate. Now the ratio of C-14 to other carbon toms in the atmosphere is known. Most scientists agree that this ratio is useful for dating items back to at least 50，000 years.(*_*)All life on Earth is made of organic molecules（分子）that contain carbon atoms coming from the atmosphere. So all living things have about the same ratio of C-14 atoms to other carbon atoms in their tissues（组织）。

Once an organism（有机体）dies it tops taking in carbon in any form，and the C-14 already present begins to decay. Over time the amount of C-14 in the material decreases，and the ratio of C-14 to other carbon toms goes down. In terms of radiocarbon dating，the fewer C-14 atoms in a sample，the older that sample is.
16 Nowadays many scientists depend on radiocarbon for dating age-old objects A Right B Wrong C Not mentioned(*_*)
17 The radiocarbon dating technique is only about 40 years old A Right B Wrong C Not mentioned(*_*)
18 An atom of ordinary carbon has six protons and eight neutrons A Right B Wrong C Not mentioned(*_*)
19 Radar is used to determine the characteristics of radiocarbon A Right B Wrong C Not mentioned(*_*)
20 Radiocarbon is reliable in dating an object back to at least 50，000 years. A Right B Wrong C Not mentioned(*_*)
21 The C-14 in an organism begins to decay when it dies A Right B Wrong C Not mentioned(*_*)
22 The half-life of C-14 is about 25，000 years. A Right B Wrong C Not mentioned(*_*)
第3部分：概括大意与完成句子（第23～30题，每题1分，共8分）(*_*)下面的短文后有2项测试任务：（1）第23～26题要求从所给的6个选项中为第1～4段每段1选择个最佳标题；（2）第27～30题要求从所给的6个选项中为每个句子确定1个最佳选项。

(*_*)Chimpanzees(*_*) 1 Chimpanzees（黑猩猩）will soon be extinct（灭绝）。

If the present rate of hunting and habitat（栖息地）destruction continues，then within 20 years，there will be no chimpanzees living in the wild. But this is more than an environmental or moral tragedy（悲剧）。

Chimpanzee extinction may also have profound implications（含意）for the survival of their distant relatives - human beings.(*_*)
2 In 1975 the biologist Marie-Claire King and Allan Wilson discovered that the human and chimpanzee genomes（基因组）match by over 98%. Compare this to the mouse，used as model for human disease in lab tests，which shares only 60% of its DNA with us. In fact，chimpanzees are far more similar to humans than they are to any other species of monkey. As well as resembling us genetically，chimps are highly intelligent and able to use tools. These facts alone should be enough to make protection of chimps an urgent priority（优先）。

But there is another，more selfish reason to preserve the chimp.(*_*)
3 The chimpanzees' trump card（王牌）comes in the field of medical research. Chimpanzees are so similar to humans that veterinarians （兽医）often refer to human medical textbooks when treating them. Yet chimpanzees do show differences in several key areas. In particular，chimps are much more resistant to a number of major diseases. It is this ability that is so interesting.(*_*)
4 For example，chimps seem to show a much higher resistance than humans to HIV，the virus that causes AIDS. Indeed，their use as experimental animals in AIDS research has declined because they are so resistant.(*_*)
5 By sequencing the chimp genome and pinpointing（找到）the place where the chimpanzee DNA sequence differs from that of humans，scientists hope to be able to discover which part of the genetic code gives chimps their increased resistance to some diseases. This，they hope，will allow them to develop new and more effective treatments for the human forms of these diseases. Such treatments could include the production of new drugs or even the alteration（改变）of the human genetic sequence. The recently completed human genome sequencing project has shown that such an effort is now well within our reach.(*_*)

第4部分：阅读理解（第31～45题，每题3分，共45分）(*_*)下面有3篇短文，每篇短文后有5道题。

请根据短文内容，为每题确定1个最佳选项。

(*_*)
第一篇Water(*_*)The second most important constituent（构成成份）of the biosphere（生物圈）is liquid water. This can only exist in a very narrow range of temperatures，since water freezes at 0℃and boils at 100℃。

Life as we know it would only be possible on the surface of a planet which had temperatures somewhere within this narrow range.(*_*)The earth's supply of water probably remains fairly constant in quantity. The total quantity of water is not known very accurately，but it is about enough to cover the surface of the globe to a depth of about two and three-quarter kilometers. Most of it is in the form of the salt water of the oceans - about 97 per cent. The rest is fresh，but three-quarters of this is in the form of ice at the Poles and on mountains，and cannot be used by living systems until melted. Of the remaining fractional which is somewhat less than one per cent of the whole，there is 10-20 times as much stored underground water as there is actually on the surface. There is also a tiny，but extremely important fraction of the water supply which is present as water vapor in the atmosphere.(*_*)Water vapor in the atmosphere is the channel through which the whole water circulation（循环）of the biosphere has to pass. Water evaporated（蒸发）from the surface of the oceans，from lakes and rivers and from moist（潮湿的）earth is added to it. From it the water comes out again as rain or snow，falling on either the sea or the land. There is，as might be expected，a more intensive evaporation per unit area over the sea and oceans than over the land，but there is more rainfall over the land than over the oceans，and the balance is restored by the runoff from the land in the form of rivers.(*_*)31 Liquid water only exists A in the center of the earth. B on the surface of our planet. C in a very narrow range of temperatures. D in the coastal areas of the earth.(*_*)32 The total quantity of water on Earth A remains almost unchanged. B has greatly increased in recent years.
C is decreasing constantly.
D is affected by global warming.(*_*)33 Most of the fresh water on Earth A is stored underground. B is in the form of ice at the Poles and on mountains. C is found in rivers and lakes. D comes from the rain.(*_*)34 The word “fraction” in the second paragraph means A a very small amount. B a large area. C an important system. D a major source of information(*_*)35 There is more of rainfall A over the mountains than over the rivers. B over the rivers than over the mountains C over the oceans than over the land. D over the land than over the oceans.(*_*)
第二篇Mind-reading Machine(*_*) A team of researchers in California has developed a way to predict what kinds of objects people are looking at by scanning（扫描）what's happening in their brains.(*_*)When you look at something，your eyes send a signal about that object to your brain. Different regions of the brain process the information your eyes send. Cells in your brain called neurons （神经元）are responsible for this processing.(*_*)The fMRI（functional Magnetic Resonance Imaging）（功能性磁振造影）brain scans could generally match electrical activity in the brain to the basic shape of a picture that someone was looking at.(*_*)Like cells anywhere else in your body，active neurons use oxygen. Blood brings oxygen to the neurons，and the more active a neuron is，the more oxygen it will consume. The more active a region of the brain，the more active its neurons，and in turn，the more blood will travel to that region. And by using fMRI，scientists can visualize（使…显现）which parts of the brain receive more oxygen-rich blood - and therefore，which parts are working to process information.(*_*)An fMRI machine is a device that scans the brain and measures changes in blood flow to the brain. The technology shows researchers how brain activity changes when a person thinks，looks at something，or carries out an activity like speaking or reading. By highlighting the areas of the brain at work when a person looks at different images，fMRI may help scientists determine specific patterns of brain activity associated with different kinds of images.(*_*)The California researchers tested brain activity by having two volunteers view hundreds of pictures of everyday objects，like people，animals，and fruits. The scientists used an fMRI machine to record the volunteers' brain activity with each photograph they looked at. Different objects caused different regions of the volunteers' brains to light up on the scan，indicating activity. The scientists used this information to build a model to predict how the brain might respond to any image the eyes see.(*_*)In a second test，the scientists asked the volunteers to look at 120 new pictures. Like before，their brains were scanned every time they looked at a new image. This time，the scientists used their model to match the fMRI scans to the image. For example，if a scan in the second test showed the same pattern of brain activity that was strongly related to pictures of apples in the first test，their model would have predicted the volunteers were looking at apples.(*_*)36 What is responsible for processing the information sent by your eyes？A The magnetic system in the brain. B The central part of the heart. C Oxygen-rich blood. D Neurons in the brain.(*_*)37 The function of an fMRI machine is A to show how neutrons take in oxygen-rich blood. B to measure how dense the blood is in the brain. C to record how much oxygen the brain consumes. D to identify which parts of the brain are processing information(*_*)38 The expression “highlighting the areas of the brain at work' in paragraph 5 means A giving light to the parts of the brain that are processing information. B marking the parts of the brain that are processing information. C putting the parts of the brain to work. D preventing the parts of the brain from working.(*_*)39 The researchers experimented on A animals and objects. B fMRI machines. C two volunteers. D thousands of pictures.(*_*)40 Which of the following can best replace the title of the passage？ A Recent Development in Science and Technology. B Your Thoughts Can Be Scanned. C A Technological Dream. D An Intelligent Robot.(*_*)
第三篇Youth Emancipation in Spain(*_*)The Spanish Government is so worried about the number of young adults still living with their parents that it has decided to help them leave the nest.(*_*)Around 55 percent of people aged 18-34 in Spain still sleep in their parents' homes，says the latest report from the country's state-run Institute of Youth.(*_*)To coax（劝诱）young people from their homes，the Institute started a “Youth Emancipation（解放）“ program this month. The program offers guidance in finding rooms and jobs.(*_*)Economists blame young people's family dependence on the precarious（不稳定的）labor market and increasing housing prices. Housing prices have risen 17 percent a year since 2000.(*_*)Cultural reasons also contribute to the problem，say sociologists（社会学家）。

Family ties in south Europe - Italy，Portugal and Greece - are stronger than those in middle and north Europe，said Spanish sociologist Almudena Moreno Minguez in her report “The Late Emancipation of Spanish Youth：Key for Understanding”。

(*_*)“In general，young people in Spain firmly believe in the family as the main body around which their private life is organized，” said Minguez.(*_*)In Spain - especially in the countryside，it is not uncommon to find entire groups of aunts，uncles，cousins，nieces and nephews（外侄/侄子）all living on the same street. They regularly get together for Sunday dinner.(*_*)Parents' tolerance is another factor. Spanish parents accept late-night partying and are wary of setting bedtime rules.(*_*)“A child can arrive home at whatever time he wants. If parents complain he'll put up a fight and call the father a fascist，” said Jose Antonio G6mez Yanez，a sociologist at Carlos III University in Madrid.(*_*)Mothers' willingness to do children's household chores（家务）worsens the problem. Dionisio Masso，a 60-year-old in Madrid，has three children in their 20s. The eldest，28，has a girlfriend and a job. But life with mum is good.(*_*)“His mum does the wash and cooks for him；in the end，he lives well，” Masso said.(*_*)41 The “Youth Emancipation” program aims at helping young people A fight for fr eedom. B live in an independent way. C fight against social injustice.
D get rid of family responsibilities.(*_*)42 It can be inferred from paragraph 5 that family ties are stronger in Portugal than in A Finland. B Greece. C Spain. D Italy.(*_*)43 Young people's family dependence can be attributed to all the following factors EXCEPT A parents' tolerance. B housing problems. C cultural traditions. D unwillingness to get married.(*_*)44 Which of the following
statements is NOT true of Dionisio Masso？A She is 60 years old. B She has a boyfriend. C She has three children. D She lives in Madrid.(*_*)45 The phrase “wary of” in paragraph 8 could be best replaced by A tired of. B afraid of. C cautious about. D worried about.(*_*)

(*_*)Reduce Packaging(*_*)Pressure increased recently on British supermarkets and retailers to reduce packaging as part of an anti-waste campaign.（46）Britain generates 4.6 million tons of household waste every year by packaging.(*_*)Dozens of people have expressed anger at the excess of plastic wrapping.(*_*)Campaigners have called on Britain to learn from other European countries.（47）When returned bottles are put in a vending machine（自动售货机），the deposit is refunded. Environmentalists warn that Britain lags behind in this.(*_*)There were reports of growing unease among consumers over the amount of packaging they have to deal with. Trade standards officers also object to excessive packaging.（48）In response to a campaign by Britain's The Independent newspaper，leading supermarkets have pointed to various initiatives to win the public confidence.（49）But campaigners said retailers and the government could learn much from anti-waste practices on the Continent. In Sweden，non-recyclable batteries have been(*_*)taxed since 1991 to encourage a switch to alternatives.（50）In Germany，plastic bags are unheard of in supermarkets and deposits are paid for reusable plastic and glass beverage bottles.(*_*) A In Belgium，when you buy something in a plastic or glass container，you make a deposit. B This is because too much padding can give buyers a false impression of what they are buying. C This has resulted in a 74 percent reduction in sales. D Tesco said it was saving 112，000 tons of cardboard a year by switching to reusable plastic crates（装货箱）for transporting its fresh produce. E The campaign was initiated by The Independent newspaper. F If a product is over-packaged，don't buy it.(*_*)

(*_*)Taking a Nap during the Day(*_*)Medical experts say most Americans do not get enough sleep. They say more Americans need to（51）for a short period in the middle of the day. They are advising people to sleep lightly（52）continuing with other activities.(*_*)One study earlier this year found that persons who sleep for a few minutes during the day were less likely to die of（53）disease. The study followed more than 2，300 Greek adults（54）about six years. Adults who rested for half an hour at least three times a week had a 37 percent lower（55）of dying from heart disease than those who did not nap.(*_*)Study organizers said the strongest（56）was in working men. They said naps might improve health by mitigating（减低）tension（57）by work.(*_*)Some European and Latin American businesses have supported the idea of（58）for many years. They urge（催促）people to（59）work，go home and have a nap before returning. In the United States，some companies let workers rest briefly in their offices. They believe this reduces mistakes and accidents，and also（60）the amount of work a person can do.(*_*)Sleep experts say it is likely that people（61）more mistakes at work than at other times. They say people should not carry out important duties（62）they feel sleepy. And they say the best thing to do is to take a nap.(*_*)About twenty minutes of rest is all you（63）。

Experts say this provides extra energy and can increase your（64）until the end of the day. But experts（65）that a nap should last no more than twenty to thirty minutes. A longer nap will put the body into deep sleep and waking up will be difficult. 51 A work B wait C live D rest 52 A between B before C besides D during 53 A heart B brain C mind D liver 54 A on B at C for D with 55 A risk B end C order D part 56 A view B argument C protest D evidence 57 A reduced B broken C caused D sensed 58 A napping B walking C working D learning 59 A repeat B improve C change D leave 60 A increases B corrects C repeats D realizes 61 A take B make C do D bring 62 A because B when C although D since 63 A forget B hope C need D admire 64 A position B pressure C demand D effectiveness 65 A warn B see C doubt D promise(*_*)

Around the world, people are starting to measure the effects of global warming - and trying to figure out what to do about it.(*_*)Scientists recently used satellites to study the temperatures of lakes around the world, and they found that lakes are heating up.Between 1985 and 2009, satellites recordedthe nighttime temperatures of the surfaces of 167 lakes. During those 24 years,
the lakes got warmer - by an average of about 0.045 degree Celsius per year.(*_*)In some places, lakes have been warming by as much as 0.10 degree Celsius per year. At that rate, a lake may warm by a full degree Celsius, or 1.8 degrees Fahrenheit, in just 10 years. That difference may seem small - you might not even notice it in your bathtub. But in a lake, slightly warmer temperatures could mean more algae, and algae can make the lake poisonous to fish.(*_*)The study shows that in some regions, lakes are warming faster than the air around them. This is important because scientists often use measurements of air temperature to study how the Earth is warming. By using lake temperatures as well, scientists can get a better picture of global warming.The scientists say data on lakes give scientists a new way to measure the impact of climate change around the world.(*_*)That's going to be useful, since no country is too big or too small to ignore climate change. Scientists aren't the only ones concerned. Everyone who lives on Earth is going to be affected by therapidwarming of the planet.Many world leaders believe we might be able to do something about it, especially by reducing the amount of greenhouse gases we put into the air.(*_*)That's why the United Nations started the Framework Convention on Climate Change, or UNFCCC. Every year the convention meets, and representatives from countries around the world gather to talk about climate change and discuss global solutions to the challenges of a warming world.(*_*)16 Scientist have been keeping records of lake temperatures for over 30 years.

(*_*)The IPad(*_*) 1 The IPad is a tablet computer (平板电脑) designed and developed by Apple. It is particularly marketed as a platform for audio and visual media such as books, periodicals (期刊), movies, music, and games, as well as web content. At about 1.5 pounds (680 grams), its size and weight are between those of most contemporary smartphones and laptop computers. Apple released the IPad in April 2010, and sold 3 million of the devices in 80 days.(*_*) 2 The IPad runs the same operating system as IPod Touch and IPhone. It can run its own applications as well as ones developed for IPhone. Without modification, it will only run programs approved by Apple and distributed via its online store.(*_*) 3 Like IPhone and iPod Touch, the IPad is controlled by a multitouch display-a break from most previous tablet computers, which uses a pressure-triggered stylus (触控笔). The IPad uses a Wi-Fi data connection to browse (浏览) the Internet, load and stream media, and install software. Some models also have a 3G wireless data connection which can connect to GSM 3G data networks. The devices is managed and synchronized (同步) by ITunes on a personal computer via USB cable.(*_*) 4 An IPad has different features and applications one can use to execute different and interesting things. There are lots of IPad applications that the owner can use to enhance the way they communicate. Some of these are how to use social networking sites and other online options. One of the most common uses is for e-mail services. IPand applications like Markdown Mail allow the adoption of specific and particular options. They enable the owner to personalize their email accounts.(*_*) 5 While the IPad is mostly used by consumers it also has been taken up by business users. Some companies are adopting IPads in their business offices by distributing or making available IPads to employees. Examples of uses in the workplace include lawyers responding to clients, medical professionals accessing health records during patient exams, and managers approving employee requests. A survey by Frost Sullivan shows that IPad usage in workplaces is linked to the goals of increased employees productivity, reduced paperwork, and increased revenue.(*_*)23、Paragraph

(*_*)第一篇Cell Phones: Hang Up or Keep Talking?(*_*)Millions of people are using cell phones today. In many places it is actually considered unusual not to use one. In many countries, cell phones are very popular with young people. They find that the phones are more than a means of communication-having a mobile phone shows that they are cool and connected.(*_*) The explosions around the world in mobile phone use make some health professional worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.(*_*)On the other hand, why do some medical studies show changes in the brain cells of some people who use mobile phones? Signs of change in the issues of the brain and head can be detected with modern scanning (扫描) equipment. In one case, a traveling salesman had to retire at a young age because of serious memory loss. He couldn't remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer's doctor didn't agree.(*_*) What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones.
