Its date have been helping astronomers predict how common planets are in our galaxy.The telescope focused on hunting planets that might have conditions similar to those on Earth.The authors of a study published in The Proceedings of the National Academy of Sciences conclude that between 14 and 30 out of every 100 stars with a mass and temperature similar to the Sun may host a planet that could support life as we know it.Such a planet would have a diameter at least as large as Earth's but no more than twice that big.The planet also would have to orbit in a stor's habitable zone. That's where the surface temperature would allow any water to exist as liquid.The new estimate of how many plantes might fit these conditions comes from studying more that 42,000 stars and identifying suitable worlds orbiting them.The scientists used those numbers to extrapolate(推算) to the rest of the stars that the telescope could not see.The estimate is rough，the authors admit. If applied to the solar system，it would define as habitable a zone starting as close ot the Sun as Venus and running to as far away as Mars. Neither planet is Earthlike(although either might have been in the distant pase). Using tighter limits the researchers estimate the between 4 and 8 out of every 100 sunlike stars could host an Earth-sized world.These are ones that would take 200 to 400 days to complete a yearly orbit.Four out of every 100 sunlike stars doesn't sound like a big number. It would mean however that the Milky Way could host more than a billion Earth-sized planets with a chance for life.16.

Anyone hoping to pedal to work there has to contend with steep streets like Canton Avenue，which famouslyclimabs at a nearly 40-degree angle.As a result，some residents avoid biking altogether.2 But University of Pittsburgh graduate Micah Toll，23，and a few friends recently launched an invention that they hope will increase the city's pedal power. An electric bike called to Pulse PEVO. A super-strong battery powers the bicycle. Able to hit nearly 20 miles per hours without pedaling，it zips battery powers the bicycle. Able to hit nearly 20 miles per hour without pedating ，it zips up the city's most daunting(令人却步的)hills.Toll hopes it will persuade people in Pittsburgh and elsewhere to get out of their cars and onto bikes.3 If it sounds like Toll has a knack(窍门) for fixing problems，that's because he does. In high school，he designed a new type of construction beam. It weights no more than a feather pillow but can be used to build sturdy(坚固的)homes for refugees fleeing war or natural disaster.For his work，Toll was invited to attend the Inter International Science and Engineering Fair(Isef)—twice，in 2006 and 2007. The annual competition for young researchers is program of Society for Science&the Public(that's the parent organization of Science News for Kids).Toll says that when it comes to science，he keeps it simple：“You see a problem and say，“How couldI solve that?”4 He's not the only to take that approach. Many young researchers get their start by trying to solve a problem or fulfill a need in their own communities.When students dedicate themselves to finding a solution that many benefit theircommunity，“a passion is ignited(点燃)，”says Wendy Hawkins，executive director of the Inter Foundation，which sponsors Intel ISEF."Finding that passion and fostering it can be the key to many students future success."she says.23.

Gardner thinks that his theory has a ________ .A. musical foundation.B. biological foundation.C. intrapersonal foundation.D. linguistic foundation.答案：ABADBMusic is one of the most beautiful forms of artistic expression是ever invented. In movies and plays，music has an added function：it not only moves people but also can shock people.Our eardrums can withstand sound within 20 to 80 decibels(分贝).Once sound exceeds this limit，even beautiful music will become ear-splitting noise and harm health.A strong blast(响声) of high sound can twist and break a solid iron sheet.High sound of 150 decibels can kill a healthy rat.In movies，sometimes the hero can produce a sound that ordinary people can't hear and only those who have the same ability can feel.In nature，there is actually sound that is beyond our hearing. In physics，the sound that exceeds 20000Hz is called ultrasonic(超音波的).Dolphins，whales and bats can make suchhigh-frequency sound.It does no harm to health.Sound less than 20Hz is called infrasonic(次声)waves. When we move，the air will vibrate. The vibration of air can produce infrasonic wave.As the frequency of infrasonic waves is close to that of people's internal organs，infrasonic wave may cause resonance(共振) in human bodies. As a result，people's vision may weaken and internal organs may rupture(断裂). However，whether an infrasonic wave can be used as a weapon depends on its intensity. If its intensity is very low，it won't damage internal organs or a person's health. If the intensity of inf让sonic wave exceeds 160 decibels，it is extremely harmful. When wind blows at a force of 3 or 4 over the sea，it will produce infrasonic waves of several decibels. Only typhoons canproduce infrasonic waves of over 100 decibels. At present，scientists can only produce infrasonic weapons in the lab with the help of advanced scientific tools and powerful electric power.36 What could be the best title of the passage?A The power of musicB The harms of noisesC The magic of soundD The discovery of infrasonic waves37 What does the author say about music?A It may be harmful to people's halthB It always cheers people upC It is very often difficult to understandD It sounds better when it is lound enough38 It is true that the soundA of nature is the most beautifulB over 80 decibels is harmful to peopleC of high intensity benefits animalsD in movies is pleasing to the ear39 An ultrasonic soundA is very loudB does harm to people's healthC cannot be heard by peopleD is produced by the hero in movies40 It can be found from the last paragraph that infrasonic wavesA are harmless to people's healthB exist in people's internal organsC can be used as deadly weaponsD can improve eyesight答案：CABCCCompact DisksIf someone says to you your music CDs don't really hold any music on them, and they only have numbers recorded on them, you may not believe it. In fact, he isright in that sound is actually recorded onto the CDs as special numbers —a digital code.1 The code is pressed onto the CD as bumps on a long spiral track almost five kilometers long. These bumps are an average of 0.5 microns wide.A small laser beam shines onto the bumps as the CD turns. The light is reflected back to a receiver that records how the laser light bounces back. This lets the CD player2 turn the reflected light back into the original code. This means you can hear the original code as music.Digital codes are used with many technologies. E-mail needs these kinds of code numbers. Space probes communicate with their ground station on earth using digital codes. Bar codes are read as digital codes in computer systems. Digital communications with cell phones need digital codes. Weather radios also tune into specific signals using these codes.There are many types of compact disks. One format is called CD-RWs. They can be recorded on and re-recorded on(rewritten on)as you would do with a floppy disk3. Another format is the CD-ROM. The technology for recording on these disks is different from other CDs. These CDs have a dye layer that the CD writer can darken or leave clear. The clear and dark spots are the digital code. CD-ROM stands for Compact Disc —Read Only Memory4. This disk is like a "super" floppy disk that can hold lots of information. One CD-ROM can hold the same amount of data as 500 floppy disks. Information is permanently recorded onto it. Computer games and other programs are considered to be CD-ROMs.CDs were first sold to the public in 1982 These CDs still play well and sound fine. Current CDs are expected to last between 70 to 200 years. Of course, you can make sure your CDs last a long time by taking care of them.Science keeps on developing. It may not be many more years before a completely new technology is invented5 and introduced to the public for music recording. In the meantime, there is no doubt you will continue to enjoy listening to your favorite music on CDs6 and playing your favorite computer games onCD-ROMs.41 Music is recorded onto CDs asA laser beamsB digital codesC musical notesD special sounds42 E-mail is mentioned in the third paragraph to showA the variety of digital communicationsB the development of new technologiesC the usefulness of digital codesD the relationship between communication and technology43 One of the differences between CD-RWs and CD-ROMs isA CD-ROMs can be used for longer timeB CD-ROMs cannot be rewritten onC CD-RWs hold more informationD CD-RWs are merely used for music recording44 CDs can last a long time ifA they are seldom usedB they play well and sound fineC their users take good care of themD they are developed with new technology45 It can be inferred from the passage thatA CD-ROMs are more expensive than other CDsB new technology for music recording is being developedC the author likes listening to musicD flppy disks are no longer in use答案：BCBCC第5部分，补全短文Do You Have a Sense of Humor?Humor and laughter are good for us. There is increasing evidence that they can heal us physically，mentally，emotionally，and spiritually. In fact，every system of the body responds to laughter in some positive，healing way. So how can we get more laughter into our lives?(46)Psychologist and author，Steve Wlison，has some answers.Many peoplebelieve that we are born with a sense of humor.They think，“either you've got it，or you don't”Dr.Wilson points out that this false.(47) The parts of brain and central nervous system that control laughing and smiling are mature at birth(48)(After all ，when a baby laughs，we don't rush over and say，“That kid has a great sense of humor!”)A sense of humor is something that you can develop over a lifetime.Sometimes people think that they don't have a good sense of humor because they are not good joke tellers.Dr.Wilson reminds us that telling jokes is only one of many ways to express humor.(49)Then we will make others laugh，too.A person who has a true sense of humor is willing and able to see the funny side of everyday life.One of the best definition of a sense of humor is“the ability to see the nonserious element in a situation.”Consider this sign from a sore window.“Any faulty merchandise will be cheerfully replanced with merchandise of equal quality.”The store manager probably placed the sign in the window to impress customers with the store's excellent service.(50)As Dr.Wilson says，“a good sense of humor means that you don't have to be funny;you just have to see what's funny.”A He advises us to lose our inhibitions(抑制)and try to laugh at ourselves.B Is it possible to develop a sense of humor?C However，that does not mean that infants have a sense of humor.D What is true，however，it that we are born with the capacity to laugh and smileE Everyone experiences this emotionF He had a serious purpose，but if you have a sense of humor，you will probably find the sign funny!答案：BDCAF第6部分：完形填空(第51~65题，每题1分，共15分)Citizen ScientistsUnderstanding how nature responds to climate change will require monitoring key life cycle1 events —flowering, the appearance of leaves, the first frog calls of the spring —all around the world. But ecologists can't be everywhere so they're turning to non-scientists, sometimes called citizen scientists, for help.Climate scientists are not present everywhere. Because there are so many places in the world and not enough scientists to observe all of them, they're asking for your help in observing signs of climate change across the world. The citizen scientist movement encourages ordinary people to observe a very specific research interest —birds, trees, flowers budding, etc. —and send their observations to a giant database to be observed by professional scientists. This helps a small number of scientists track a large amount of data that they would never be able to gather on their own. Much like citizen journalists helping large publications cover a hyper-local beat2, citizen scientists are ready for the conditions where they live. All that's needed to become one is a few minutes each day or each week to gather data and send it in.A group of scientists and educators launched an organization last year called the National Phenology4Network. “Phenology”is what scientists call the study of the timing of events in nature.One of the group's first efforts relies on scientists and non-scientists alike to collect data about plant flowering and leafing every year. The program, called Project Bud Burst, collects life cycle data on a variety of common plants from acrossthe United States. People participating in the project —which is open to everyone —record their observations on the Project Bud Burst website.“People don't have to be plant experts —they just have to look around and see what's in their neighborhood,”says Jennifer Schwartz, an education consultant with the project. “As we collect this data, we'll be able to make an estimate of how plants and communities of plants and animals will respond as the climate changes.”51 A everywhere B anywhere C somewhere D nowher52 A If B Although C When D Because53 A giving B showing C developing D observing54 A special B professional C skillful D ordinary55 A on B at C to D with56 A small B limited C smple D large57 A Very B Much C AsD Many58 A All B Any C Some D Most59 A send B print C answer D keep60 A known B featured C belonged D called61 A alike B like C unlike D likely62 A points B wonders C data D interests63 A common B suitable C open D strange64 A want B forget C mind D have65 A who B how C before D since ADDDC BDAAD ACCDB。

Green roofs are the most prevalent（流行）in Germany，which is widely regarded as the leader in green roof research.The green roofs that are used these days can be classified as 'extensive' and'intensive' systems. Extensive green roofs use mosses，grasses and herbs，which are tolerant to droughts. These plants do not Reed much maintenance. can be grown in a layer of substrate（土层）that can be as shallow as l.5 inches，and generally are inaccessible to the public. In contrast, a wide range of species of plants are grown on intensive green roofs，such as shrubs（灌木）and even trees，which require deeper substrate layers，and are usually grown on flat roofs. They need intensive maintenance, and are usually areas that resemble parks which are accessible to people.There are several benefits of adopting green roof technologies. Apart from the obvious psychological and aesthetic（美学的）benefits of garden-like environments surrounding you，some of the common economic and ecological benefits are：a reduction in the consumption of energy；air and water purification；recovering green spaces；and the mitigation（缓解）of the heat island effect in urban areas.The green roof research that is currently ongoing is focused on evaluating the species of plants that are suitable to be grown on roofs，the methods of propagation（繁殖）as well as establishment，nutrient（养料）and water requirement，substrates，and the quantity and quality of water runoff. The evaluation criteria of plant species are：at what rate they can be established：their capacity to withstand invasive weeds：tolerance of cold and heat: tolerance of drought conditions: capacity of persistence and survival.A number of experiments are being conducted on roof platform simulations at various research centers. These sites are generally outfitted with equipment，which are used to measure temperatures at different depths of the growing substrates, and the rate and volume of the runoff of stormwaters from each of the platforms.Green roof technology is representative of a completely new market for landscape contractors. And all roofs that currently exist and the future ones to be constructed are the potential market-a market that is too huge to be overlooked.16It is estimated that around 10 percent of the flat roofs in Germany are green.A RightB WrongC Not mentioned17German people prefer extensive green roof systems to intensive ones.A RightB WrongC Not mentioned18Small plants like grasses and herbs are grown widely on intensive green roofs.A RightB WrongC Not mentioned19Green roof is an ecologically sound strategy of spreading green in urban areas.A RightB WrongC Not mentioned200ne of the benefits of green roofs is the reduction of the heat island effect in cities.A RightB WrongC Not mentioned21 0ne focus；n the green roof research is the evaluation of suitable plant species.A RightB WrongC Not mentioned22 Although green roof technology can create a garden-like environment，its potential marketis rather small.A RightB WrongC Not mentioned第5部分：补全短文（第46 ～50题，每题2分，共10分）下面的短文有5处空白，短文后有6个句子，其中5个取自短文，请根据短文内容将其分别放回原有位置，以恢复文章原貌。

A级—理工类第一部分阅读理解Black Holes Trigger Stars to Self-DestructScientists have long understood that super massive black holes weighing millions or billions of suns can tear apart stars that come too close. The black hole's gravity pulls harder on the nearest part of the star, an imbalance that pulls the star apart over a period of minutes or hours, once it gets close enough.Scientists say this uneven pulling is not the only hazard facing the star. The strain of these unbalanced forces can also trigger a nuclear explosion powerful enough to destroy the star from within. Matthieu Brassart and Jean-Pierre Luminet of the Observatoire de Paris in Meudon, France, carried out computer simulations of the final moments of such an unfortunate star's life, as it veered towards a super massive black hole.When the star gets close enough, the uneven forces flatten it into a pancake shape. Some previous studies had suggested this flattening would increase the density and temperature inside the star enough to trigger intense nuclear reactions that would tear it apart. But other studies had suggested that the picture would be complicated by shock waves generated during the flattening process and that no nuclear explosion should occur.The new simulations investigated the effects of shock waves in detail, and found that even when their effects are included, the conditions favor a nuclear explosion. "There will be an explosion of the star —it will be completely destroyed," Brassart says. Although the explosion obliterates the star, it saves some of the star's matter from being devoured by the black hole. The explosion is powerful enough to hurl much of the star's matter out of the black hole's reach, he says.The devouring of stars by black holes may already have been observed, although at a much later stage. It is thought that several months after the event that rips the star apart, its matter starts swirling into the hole itself. It heats up as it does so, releasing ultraviolet light and X-rays.If stars disrupted near black holes really do explode, then they could in principle allow these events to be detected at a much earlier stage, says Jules Halpern of Columbia University in New York, US. "It may make it possible to see the disruption of that star immediately if it gets hot enough," he says.Brassart agrees. "Perhaps it can be observed in the X-rays and gamma rays, but it's something that needs to be more studied," he says. Supernova researcher Chris Fryer of the Los Alamos National Laboratory inLos Alamos, New Mexico, US , says the deaths of these stars are difficult to simulate, and he is not sure whether the researchers have proven their Case that they explode in the process.练习：1.

"Too Little for Global WarmingOil and gas will run out1 too fast for doomsday global warming scenarios to materialize, according to a controversial new analysis presented this week at the University of Uppsala in Sweden. The authors warn that all the fuel will be burnt before there is enough carbon dioxide in the atmosphere to realize predictions of melting ice caps and searing temperatures. Defending their predictions, scientists from the Intergovernmental Panel on Climate Change saythey considered a range of estimates of oil and gas reserves, and point out that coal-burning could easily make up the shortfall. But all agree that burning coal would be even worse for the planet.The IPCC's predictions of global meltdown pushed forward the 1997 Kyoto Protocol, an agreement obliging signatory nations to cut CO2 emissions. The IPCC considered a range of future scenarios, from unlimited burning of fossil-fuels to a fast transition towards greener energy sources. But geologists Anders Sivertsson, Kjell Aleldett and Colin Campbell of Uppsala University say there is not enough oil and gas left even the most conservative of the 40 IPCC scenarios to come to pass.Although estimates of oil and gas reserves vary widely, the researchers are part of a growing group of experts who believe that oil supplies will peak as soon as 2010, and gas soon after. Their analysis suggests that oil and gas reserves combined amount to the equivalent of about 3,500 billion barrels of oil considerably less than the 5,000 billion barrels estimated in the most optimistic model envisaged by the IPCC. Even the average forecast of about 8,000 billion barrels is more than twice the Swedish estimate of the world's remaining reserves. Nebojsa Nakicenovic, an energy economist at the University of Vienna, Austria who headed the 80-strong IPCC team that produced the forecasts, says the panel's work still stands. He says they factored in a much broader and internationally accepted range of oil and gas estimates than the "conservative" Swedes.Even if oil and gas run out, "there's a huge amount of coal underground that could be exploited", he says that burning coal could make the IPCC scenarios come true, but points out that such a switch would be disastrous. Coal is dirtier than oil and gas and produces more CO2for each unit of energy, as well as releasing large amounts of particulates. He says the latest analysis is a "shot across the bows'' for policy makers.练习：1. What do the authors of the new analysis presented at the University of Uppsala intend to say?A) The burning of coal will accelerate the arrival of Earth's doomsday.B) The oil reserves are big enough to materialize the doomsday scenarios.C) Melting ice caps and searing temperatures exist only in science fiction.D) Oil and gas will run out so fast that Earth's doomsday will never materialize.2. Nations that signed the Kyoto Protocol agree toA) pay attention to global meltdown. B) cut CO2 emissions.C) use more green energy. D) stop using fossil fuels.3. What are the estimates of the world's oil and gas reserves?A) 4,000 billion barrels by the average forecast. B) 8,000 billion barrels estimated by the Swedes.C) 3,500 barrels envisaged by IPCC. D) 3,500 billion by a growing number of scientists.4. Which of the following about Nebojsa Nakicenovic is true?A) He thinks fossil fuels are as dirty as oil and gas.B) He thinks green fuels will replace oil and gas eventually.C) He thinks IPCC's view on the world's oil reserves is too optimistic.D) He thinks that IPCC's estimates are more optimistic than the Swedes.5. Which of the following is the near explanation of Nakicenovic's assertionthat "... such a switch would be disastrous ..."?A) The IPCC scenarios would come true because burning coal will emit largeramounts of CO2.B) A switch to burning coal would produce disastrous environmental problems.C) Oil and gas to replace coal as fuel would speed up the process of global warming.D) A switch from the IPCC scenarios to the policymakers' ones would be disastrous.U.S. Scientists Confirm Water on MarsNASA scientists said that Mars was covered once by vast lakes, flowing rivers and a variety of other wet environments that had the potential to support life. Laboratory tests aboard NASA's Phoenix Mars Lander have identified water in a soil sample. The lander's robotic arm delivered the sample Wednesday to an instrument that identifies vapors produced by the heating of samples."We have water," said William Boynton of the University of Arizona, lead scientist for the Thermal and Evolved-Gas Analyzer, or TEGA. "This is the first time Martian water has been touched and tasted."The robotic arm is a critical part of the Phoenix Mars mission. It is needed to trench into the icy layers of northern polar Mars and deliver samples to instruments that will analyze what Mars is made of, what its water is like, and whether it is or has ever been a possible habitat for life.The soil sample came from a trench approximately 2 inches deep. When the robotic arm first reached that depth, it hit a hard layer of frozen soil. Two attempts to deliver samples of icy soil on days when fresh material was exposed were foiled when the samples became stuck inside the scoop. Most of the material in Wednesday's sample had been exposed to the air for two days, letting some of the water in the sample vaporize away and making the soil easier to handle."Mars is giving us some surprises," said Phoenix principal investigator Peter Smith of the University of Arizona. "We're excited because surprises are where discoveries come from. One surprise is how the soil is behaving. The ice-rich layers stick to the scoop when poised in the sun above the deck, different from what we expected, from all the Mars simulation testing we've done so far."Since landing on May 25, Phoenix has been studying soil with a chemistry lab, TEGA, a microscope, a conductivity probe and cameras. The science team is trying to determine whether the water ice ever thaws enough to be available for biology and if carbon-containing chemicals and other raw materials for life are present. The mission is examining the sky as well as the ground. A Canadian instrument is using a laser beam to study dust and clouds overhead."It's a 30-watt light bulb giving us a laser show on Mars," said Victoria Hipkin of the Canadian Space Agency.A full-circle, color panorama of Phoenix's surroundings also has been completed by the spacecraft."The details and patterns we see in the ground show an ice-dominated terrain as far as the eye can see," said Mark Lemmon of Texas A & M University, lead scientist for Phoenix's Surface Stereo Imager camera. "They help us plan measurements we're making within reach of the robotic arm and interpret those measurements on a wider scale."练习：1. What was discovered by NASA's Phoenix Mars Lander on Mars?A Vast lakes.B Flowing rivers.C Water in a soil sample.D Living things.2. Why did the first two attempts to deliver samples fail?A The sample vaporized away.B Fresh material was exposed to the air.C The samples got stuck inside the scoop.D The robotic arm hit a hard rock.3.

Where are the scientists involved in the research from?A They are from America.B They are from Canada.C They are from both America and Canada.D They are from neither America nor Canada.5. Which of the following do you think is the best description of Phoenix's Surface Stereo Imager camera, according to your understanding of the passage?A It imitates human vision and is able to capture three-dimensional images.B It imitates human voice and is able to record slight sounds while taking photos.C It takes clear photos that show every detail of the object.D It is this particular type of camera that can take wide angle pictures."Hidden" Species May Be Surprisingly Common Cryptic species — animals that appear identical but are genetically quite distant —may be much more widespread than previously thought. The findings could have major implications in areas ranging from biodiversity estimates and wildlife management, to our understanding of infectious diseases and evolution.Reports of cryptic species have increased dramatically over the past two decades with the advent of relatively inexpensive DNA sequencing technology. Markus Pfenninger and Klaus Schwenk, of the Goethe-Universitat in Frankfurt, Germany, analyzed all known data on cryptic animal species and discovered that they are found in equal proportions throughout all major branches of the animal kingdom and occur in equal numbers in all biogeographical regions.Scientists had previously speculated that cryptic species were predominantly found in insects and reptiles, and were more likely to occur in tropical rather than temperate regions. “Species that are seemingly widespread and abundant could in reality be many different Cryptic species that have low populations and are highly endangered," says Pfenninger. Until the genetic information of all species in at least one taxon is thoroughly studied, no one will know just how many cryptic species exist, "It could be as high as 30%, Pfenninger says."I'm extremely surprised by their results," says Alex Smith of the University of Guelph in Ontario, Canada. "It's a call to arms to keep doing the broad kind of genetic studies that we are doing. "Sampling as many individuals as possible, scientists hope to complete. work on all fish and birds in another 5 to 10 years. Once either of these taxonomic groups is completed, Pfenninger says researchers will be able to decide how many cryptic species exist throughout the animal kingdom.Examples of cryptic species include the African elephant. A 2001 study found the elephants were actually two genetically distinct, non-interbreeding species, the African bush elephant and the African elephant. The species are currentlylisted as vulnerable and threatened, respectively, by the World Conservation Union (WCU).The reclassifications are more than an academic exercise. They define populations that have evolved independently of each other and whose genetic differences can have significant consequences.In the early 1900s misidentification of mosquito species based on morphology confused: attempts to control malaria in Europe. Ultimately, what was thought to be a single species was actually made up of six sibling species, only three of which transmitted the disease. "The basic unit in biology is always the species, and you have to know what you are dealing with," Pfenninger says. Much previous research is now no longer used, he Says, because it is not clear what species was being studied.练习：1. Which of the following about the significance of the research on cryptic species is NOT true?A The results of the research can help the development of many other research areas.B The results of the research can help the development of biodiversity estimates.C The results of the research can help our understanding of infectious disease evolution.D The results of the research can help our understanding of "survival of the fittest. "2. What was scientists' understanding of cryptic species?A They occurred in equal numbers in all biogeographical regions.B They were mostly found in insects and reptiles.C They were likely to be in tropical rather than temperate regions.D Both Band C.3. Do scientists know how many cryptic species exist?A Not yet.B Yes, they do.C They will know the answer in another one or two-years.D They will never know the answer.4. Which of the following about the African bush elephant and the African elephant is true?A The WCU are interbreeding those elephants.B They are interbreeding species.C They are two genetically distant species.D They depend on each other for survival.5. People were confused in their attempts to control malaria in Europe inthe early 1900s. because scientistsA identified only one mosquito species instead of six species.B thought only three mosquito species transmitted disease.C thought there was only one mosquito species.D did not know what species was being studied.Thirsty in Karachi （卫生A）After two weeks in Karachi, I’m not sure whether to laugh or to cry. Either way, it involves water—or rather the lack of it.In Western Europe or the US, you only have to turn on the tap and you’ll see a jet of cold water, ready to drink, cook and bathe in, or wash the car. Turn on the tap in Karachi and you’ll be lucky to fill a few buckets. Until 1947 the city was part of British India, whose engineers built and maintained a modest water supply network for the city’s 500,000 inhabitants. Today, Karachi is home to around 12 million people. Half of them live in slum townships, with little or no water through the mains. Even the rich half usually have to wait days before anything tickles through their pipes. And the coloured liquid that finally emerges is usually too contaminated to drink.Half usually have to wait days before anything tickles through their pipes. And the coloured liquid that finally emerges is usually too contaminated to drink.According to the state-owned Karachi Water and Sewerage Board, the city needs more than 2,500 million litres of water each day. The board currently supplies 1,650 million litres of which nearly 40 per cent is lost from leaks—and theft. Leaks are dime a dozen to water utilities the world over, but theft?Karachi’s unlikely water pirates turn out to be ordinary families struggling to get adequate supplies of one of life’s necessities. Stea ling water takes many forms. The simplest is to buy a suction pump and get it attached to the water pipe that feeds your house from the mains. This should maximize your share of water every time the board switches on the supply. When the practice started 20 years ago, the pumps would be carefully hidden or disguised as garden ornaments. These days people hardly bother. The pumps are so widespread and water board inspectors so thin on the ground that when officials do confiscate a pump its owner simply buy a replacement.Insisting that people obey the law won’t work because most households have little alternative but to steal. For its part, the Karachi Water and Sewerage Board says it would dearly like to make life easier, but finds itself mired in debt beca use most residents either won’t pay water charges or can’t afford to the Urban Resource Centre, a Karachi-based think tank, of the 1.2 million known consumers of water only 750,000 are billed, of whom just 163,000 actually pay for their supplies. The board makes a perpetual loss, and there is no money to improve the system or even plug the leaks. Worse, the board increasingly relies on international loans from institutions such as the Asian Development Bank, which only makes its debt worse.The joke is that the owners of the suction pumps end up with little—if any—extra water. Your house is in a line with 20 other households all tapping into one horizontal pipeline. All you can end up doing, given you have pumps of equal strength, is redistri bute each other’s entitlement and pay higher electricity bills into the bargain.Back home in London, I’ll remember not to complain about the water meter, or the hosepipe ban.练习：1．According to the passage, people in Karachi today suffer from a short supply of water becauseA. the water supply network built in 1947 has stopped to function.B. the city has become much larger than before.C. old networks can not meet the need of the city’s greatly-increased population.D. other city is longer a part of British India.2. Now people in Karachi do not hide or disguise the suction pumps they use to steal water becauseA. the pumps are no longer wanted as garden ornaments.B. water supply board officials no longer confiscate them.C. it does not cost much money to buy a new one.D. many households have them and there are very few inspectors around to try to find them.3. Confronted with a severe shortage of water supply, the city’s Water and Sewerage BoardA. tries to improve the water supply system with borrowed money.B. is not making any effort to improve the situation.C. urges the consumers to obey the law.D. charges the consumers more for the water they use.4.Which of the following is true of the owners of the suction pumps, if their neighbors have equally powerful pumps as they do?A. They get some extra water.B. They only pay more for electricity.C. They share what they can get with their neighbors.D. They replace their pumps with new ones.5. Which of the following is true about the author when he is back home in London?A. He misses the days he spent in Karachi.B. He forgets the complaints he made in Karachi.C. He is content with the water supply in London.D. he complains about the water supply in London.（注：可编辑下载，若有不当之处，请指正，谢谢!）。

Free Statins With Fast Food Could Neutralize Heart RiskFast food outlets could provide statin drugs free of 1charge so that customers can reduce the heart disease dangers of fatty food, researchers at Imperial College London 2suggest in a new study．Statins reduce the 3amount ofunhealthy ”LDL” cholesterol in the blood. A wealth of trial data has proven them to be highly effective at lowering a person’s heart attack4risk .In a paper published in the American Journal of Cardiology，Dr Darrel Francis and colleagues calculate that the reduction in heart attack risk offered by a statin is 5enough to offset the increase in heart attack risk from 6eating a cheeseburger and drinking a milkshake．Dr Francis，from the National Heart and Lung Institute at Imperial College London，who is the senior author of the study, said:”Statins don’t cut out a11 of the 7unhealthy effects of cheeseburgers and French fries．It’s better to avoid fatty food altogether．But we’ve worked out that in terms of your 8possobility of having a heart attack. Taking a statin can reduce your risk to more or lessthesame 9degree as a fast food meal increases it.”“It’s ironic that people are free to take as many unhealthv condiments in fast food outletsas they 10like , but statins, which are beneficial to heart health, have to be prescribed. It makes sense to make risk-reducing statins available just as easily as the unhealthy condiments that are 11provided free of charge．It would cost less than 5 penceper 12customer ---not much different to a sachet of sugar.” Dr Francis said．When people engage in risky behaviours like driving or smoking, they’re encouraged to take 13measures that lower their risk, 1ike 14wearing a seatbelt or choosing cigarettes with filters. Taking a statin is a rational way of 15lowering some of the risks of eating a fatty meal．Sharks Perform a Service for Earth’s WatersIt is hard to get people to think of sharks as anything but a deadly enemy1. They are thought to 1 attack people frequently. But these fish2 perform a 2 valuable service for earth's waters and for human beings. Yet business and sport fishing3 are threatening their 3 existence Some sharks are at risk of disappearing from 4 EarthWarm weather may influence both fish and shark activity. Many fish swim near coastal areas 5 because of their warm waters. Experts say sharks may follow the fish into the same areas, 6 where people also swim. In fact, most sharks do not purposely charge at or bite humans. They are thought to mistake a person 7 for a sea animal, such as a seal or sea lion. That is why people should not swim in the ocean when the sun goes down or comes up. Those are the 8 times when sharks are looking for food. Experts also say that bright colors and shiny jewelry may cause sharks to attack. A shark has an extremely good sense of smell4. It can find small amounts of substances in water, such as blood, body liquids and 9 chemicals produced by animals. These powerful 10 senses help sharks find their food. Sharks eat fish, any 11 other sharks, and plants that live in the ocean.Medical researchers want to learn more about the shark’s body defense, and immune 12 systems against disease. Researchers know that sharks 13 recover quickly from injuries. They study the shark in hopes of finding a way to fight human disease.Sharks are important for the world’s 14 oceans . They eat injured and diseased fish. Their hunting activities mean that the numbers of other fish in ocean waters do not become too 15 great . This protects the plants and other forms of life that exist in the oceans.Liquefaction” Key to Much of Japanese Earthquake DamageThe massive subduction zone1 earthquake in Japan caused a significant level of soil "liquefaction"2 that has surprised researchers with its 1 widespread severity, a new analysis shows."We've seen localized3 examples of soil liquefaction as extreme as this before, but the distance and 2 extent of damage in Japan were unusually severe," said Scott Ashford, a professor of geotechnical engineering4 at Oregon State University5. "Entire structures were tilted and sinking into the sediments," Ashford said. "The shifts in soil destroyed water, drain and gas pipelines6, crippling the utilities and infrastructure these communities need to 3 function . We saw some places that sank as much as four feet."Some degree of soil liquefaction7 is common in almost any major earthquake. It's a phenomenon in which soils soaked with water, particularly recent sediments or sand, can lose much of their 4 strength and flow during an earthquake. This can allow structures to shift or sink or 5 collapse.But most earthquakes are much 6 shorter than the recent event in Japan, Ashford said. The length of the Japanese earthquake, as much as five minutes, may force researchers to reconsider the extent of liquefaction damage possibly occurring in situations such as this8."With such a long-lasting earthquake, we saw 7 how structures that might have been okay after 30 seconds just continued to sink and tilt as the shaking continued for several more minutes," he said. "And it was clear that younger sediments, and especially areas built on 8 recently filled ground, are much more vulnerable."The data provided by analyzing the Japanese earthquake, researchers said, should make it possible to improve the understanding of this soil 9 phenomenon and better prepare for it in the future. Ashford said it was critical for the team to collect the information quickly, 10before damage was removed in the recovery efforts9."There's no doubt that we'll learn things from what happened in Japan10 that11 will help us to reduce risks in other similar 11events," Ashford said. "Future construction in some places may make more use of techniques known to reduce liquefaction, such as better compaction to make soils dense, or use of reinforcing stone columns."Ashford pointed out that northern California have younger soils vulnerable to liquefaction ---on the coast, near river deposits or in areas with filled ground. The "young" sediments, in geologic terms, may be those 12 deposited within the past 10,000 years or more. In Oregon, for instance, that describes much of downtown Portland, the Portland International Airport and other cities.Anything 13 near a river and old flood plains is a suspect12, and the Oregon Department of Transportation has already concluded that 1,100 bridges in the state are at risk from an earthquake. Fewer than 15 percent of them have been reinforced to 14 prevent collapse. Japan has suffered tremendous losses in the March 11 earthquake, but Japanese construction 15 standards helped prevent many buildings from collapse ---even as they tilted and sank into the ground.==Batteries Built by VirusesWhat do chicken pox，the common cold, the flu，and AIDS have in common?1．According to the first paragraph，people try to C. stay away from viruses because they are causes of various diseases．2．What is Belcher's team doing at present?C.

In one experiment, in order to make 7 participants feel lonely, the researchers had them write for six minutes about a fight with someone close to them．Others were given an emotionally neutral writing assignment. Then, some people in each 8 group wrote about the experience of eating a comfort food and others wrote about eating a new food．9 Finally,the researchers had participants 10 complete questions about their levels of loneliness．Writing about a fight with a close person made people feel lonely．But people who were generally 11 secure in their relationships would feel less lonely by writing about a comfort food．"We have found that comfort foods are consistently associated with those close to us．"says Troisi．"Thinking about or consuming these foods later then serves as a reminder of those close others．"In 12 their essays on comfort food, many people wrote about the 13 experience of eating food with family and friends. In another experiment, 14 eating chicken soup in the lab made people think more about relationships, but only if they considered chicken soup to be a comfort food．This was a question they had been asked long before the experiment, along with many other questions, so they wouldn’t remember it. Throughout everyone’s daily lives they experience s tress, often associated with our 15 connections with others," Troisi says．"Comfort food Can be an easy remedy for loneliness．Cell Phones Increase Traffic, Pedestrian Fatalities Cell phones are a danger on the road in more ways than one.1 The two new studies, lead-authored by Professor Peter D. Loeb D both A and C.2 According to the second paragraph, when did cell phones actually help to reduce pedestrian and traffic fatalities?

第1题New Attempts to Eradicate AIDS VirusA high-profile attempt to eradicate the AIDS virus in a few patients continues to show promise.But researchers won't know for a year or more whether it will work, scientist David Ho told journalists this Wednesday for the Fourth Conference in Viruses and Infections."This is a study that's in progress," says Ho, head of the Aaron Diamond AIDS Research Center, New York.The study involves 20 people who started combinations of anti-HIV drugs very early in the course of the disease, within 90 days of their infections. They've been treated for up to 18 months. Four others have dropped out because of side effects or problems complying with the exacting drug system.The drugs have knocked the AIDS virus down to undetectable levels in the blood of all remaining patients. And, in the latest development, scientists have now tested lymph nodes and semen from a few patients and found no virus reproducing there, Ho says. "Bear in mind that undetectable does not equal absent," Ho says.Ho has calculated that the drugs should be able to wipe out remaining viruses — at least from known reservoirs throughout the body — in two to three years. But the only way to prove eradication would be to stop the drugs and see if the virus comes back. On Wednesday,' Ho said he wouldn't ask any patient to consider that step before 2 years of treatment. And he emphasized that he is not urging widespread adoption of such early, aggressive treatment outside of trials. No one knows the long-term risks. But other scientists are looking at similar experiments. A federally funded study will put 300 patients on triple-drug treatments and then see if some responding well after six months can continue to suppress the virus on just one or two drugs, says researcher Douglas Richman of the University of California, San Diego. Some patients in that study also may be offered the chance to stop therapy after 18 months or more, he says.According to the passage, the attempt to eradicate the AIDS virus ______.A continues to be hopefulB will be successful in a yearC will be successful in futureD will stop being hopeful【正确答案】：A【本题分数】：3.0分【答案解析】[解析] 利用题干中的核心词“the attempt”作为答案线索，同时注意利用备选项中的核心词 hopeful和successful，这样发现答案相关句：Ahigh-profile attempt to eradicate the AIDS virus in a few patients continues to show promise(与A中的hopeful呼应)．这个句子的意思是“为消除一些病人身体中的AIDS病毒所做的尝试一直显示出希望”，根据这句话的内容判断A(一直显现出希望)是答案。

A级—理工类第一部分阅读理解Black Holes Trigger Stars to Self-DestructScientists have long understood that super massive black holes weighing millions or billions of suns can tear apart stars that come too close. The black hole's gravity pulls harder on the nearest part of the star, an imbalance that pulls the star apart over a period of minutes or hours, once it gets close enough.Scientists say this uneven pulling is not the only hazard facing the star. The strain of these unbalanced forces can also trigger a nuclear explosion powerful enough to destroy the star from within. Matthieu Brassart and Jean-Pierre Luminet of the Observatoire de Paris in Meudon, France, carried out computer simulations of the final moments of such an unfortunate star's life, as it veered towards a super massive black hole.When the star gets close enough, the uneven forces flatten it into a pancake shape. Some previous studies had suggested this flattening would increase the density and temperature inside the star enough to trigger intense nuclear reactions that would tear it apart. But other studies had suggested that the picture would be complicated by shock waves generated during the flattening process and that no nuclear explosion should occur.The new simulations investigated the effects of shock waves in detail, and found that even when their effects are included, the conditions favor a nuclear explosion. "There will be an explosion of the star — it will be completely destroyed," Brassart says. Although the explosion obliterates the star, it saves some of the star's matter from being devoured by the black hole. The explosion is powerful enough to hurl much of the star's matter out of the black hole's reach, he says.The devouring of stars by black holes may already have been observed, although at a much later stage. It is thought that several months after the event that rips the star apart, its matter starts swirling into the hole itself. It heats up as it does so, releasing ultraviolet light and X-rays.If stars disrupted near black holes really do explode, then they could in principle allow these events to be detected at a much earlier stage, says Jules Halpern of ColumbiaUniversity in New York, US. "It may make it possible to see the disruption of that star immediately if it gets hot enough," he says.Brassart agrees. "Perhaps it can be observed in the X-rays and gamma rays, but it's something that needs to be more studied," he says. Supernova researcher Chris Fryer of the Los Alamos National Laboratory in Los Alamos, New Mexico, US , says the deaths of these stars are difficult to simulate, and he is not sure whether the researchers have proven their Case that they explode in the process.练习：1.

"Too Little for Global WarmingOil and gas will run out1 too fast for doomsday global warming scenarios to materialize, according to a controversial new analysis presented this week at the University of Uppsala in Sweden. The authors warn that all the fuel will be burnt before there is enough carbon dioxide in the atmosphere to realize predictions of melting ice caps and searing temperatures. Defending their predictions, scientists from the Intergovernmental Panel on Climate Change say they considered a range of estimates of oil and gas reserves, and point out that coal-burning could easily make up the shortfall. But all agree that burning coal would be even worse for the planet. The IPCC's predictions of global meltdown pushed forward the 1997 Kyoto Protocol, an agreement obliging signatory nations to cut CO2 emissions. The IPCC considered a range of future scenarios, from unlimited burning of fossil-fuels to a fast transition towards greener energy sources. But geologists Anders Sivertsson, Kjell Aleldett and Colin Campbell of UppsalaUniversity say there is not enough oil and gas left even the most conservative of the 40 IPCC scenarios to come to pass.Although estimates of oil and gas reserves vary widely, the researchers are part of a growing group of experts who believe that oil supplies will peak as soon as 2010, and gas soon after. Theiranalysis suggests that oil and gas reserves combined amount to the equivalent of about 3,500 billion barrels of oil considerably less than the 5,000 billion barrels estimated in the most optimistic model envisaged by the IPCC. Even the average forecast of about 8,000 billion barrels is more than twice the Swedish estimate of the world's remaining reserves.Nebojsa Nakicenovic, an energy economist at the University of Vienna, Austria who headed the 80-strong IPCC team that produced the forecasts, says the panel's work still stands. He says they factored in a much broader and internationally accepted range of oil and gas estimates than the "conservative" Swedes.Even if oil and gas run out, "there's a huge amount of coal underground that could be exploited", he says that burning coal could make the IPCC scenarios come true, but points out that such a switch would be disastrous. Coal is dirtier than oil and gas and produces more CO2 for each unit of energy, as well as releasing large amounts of particulates. He says the latest analysis is a "shot across the bows'' for policy makers.练习：1. What do the authors of the new analysis presented at the University of Uppsala intend to say?A) The burning of coal will accelerate the arrival of Earth's doomsday.B) The oil reserves are big enough to materialize the doomsday scenarios.C) Melting ice caps and searing temperatures exist only in science fiction.D) Oil and gas will run out so fast that Earth's doomsday will never materialize.2. Nations that signed the Kyoto Protocol agree toA) pay attention to global meltdown. B) cut CO2 emissions.C) use more green energy. D) stop using fossil fuels.3. What are the estimates of the world's oil and gas reserves?A) 4,000 billion barrels by the average forecast. B) 8,000 billion barrels estimated by the Swedes.C) 3,500 barrels envisaged by IPCC. D) 3,500 billion by a growing number of scientists.4. Which of the following about Nebojsa Nakicenovic is true?A) He thinks fossil fuels are as dirty as oil and gas.B) He thinks green fuels will replace oil and gas eventually.C) He thinks IPCC's view on the world's oil reserves is too optimistic.D) He thinks that IPCC's estimates are more optimistic than the Swedes.5. Which of the following is the near explanation of Nakicenovic's assertion that "... such a switchwould be disastrous ..."?A) The IPCC scenarios would come true because burning coal will emit larger amounts of CO2.B) A switch to burning coal would produce disastrous environmental problems.C) Oil and gas to replace coal as fuel would speed up the process of global warming.D) A switch from the IPCC scenarios to the policymakers' ones would be disastrous.U.S. Scientists Confirm Water on MarsNASA scientists said that Mars was covered once by vast lakes, flowing rivers and a variety of other wet environments that had the potential to support life.Laboratory tests aboard NASA's Phoenix Mars Lander have identified water in a soil sample. The lander's robotic arm delivered the sample Wednesday to an instrument that identifies vapors produced by the heating of samples."We have water," said William Boynton of the University of Arizona, lead scientist for the Thermal and Evolved-Gas Analyzer, or TEGA. "This is the first time Martian water has been touched and tasted."The robotic arm is a critical part of the Phoenix Mars mission. It is needed to trench into the icy layers of northern polar Mars and deliver samples to instruments that will analyze what Mars is made of, what its water is like, and whether it is or has ever been a possible habitat for life.The soil sample came from a trench approximately 2 inches deep. When the robotic arm first reached that depth, it hit a hard layer of frozen soil. Two attempts to deliver samples of icy soil on days when fresh material was exposed were foiled when the samples became stuck inside the scoop. Most of the material in Wednesday's sample had been exposed to the air for two days, letting some of the water in the sample vaporize away and making the soil easier to handle. "Mars is giving us some surprises," said Phoenix principal investigator Peter Smith of the University of Arizona. "We're excited because surprises are where discoveries come from. One surprise is how the soil is behaving. The ice-rich layers stick to the scoop when poised in the sun above the deck, different from what we expected, from all the Mars simulation testing we've done so far."Since landing on May 25, Phoenix has been studying soil with a chemistry lab, TEGA, a microscope, a conductivity probe and cameras. The science team is trying to determine whether the water ice ever thaws enough to be available for biology and if carbon-containing chemicals and other raw materials for life are present.The mission is examining the sky as well as the ground. A Canadian instrument is using a laser beam to study dust and clouds overhead."It's a 30-watt light bulb giving us a laser show on Mars," said Victoria Hipkin of the Canadian Space Agency.A full-circle, color panorama of Phoenix's surroundings also has been completed by the spacecraft. "The details and patterns we see in the ground show an ice-dominated terrain as far as the eye can see," said Mark Lemmon of TexasA & MUniversity, lead scientist for Phoenix's Surface Stereo Imager camera. "They help us plan measurements we're making within reach of the robotic arm and interpret those measurements on a wider scale."练习：1.

The findings could have major implications in areas ranging from biodiversity estimates and wildlife management, to our understanding of infectious diseases and evolution.Reports of cryptic species have increased dramatically over the past two decades with the advent of relatively inexpensive DNA sequencing technology. Markus Pfenninger and Klaus Schwenk, of the Goethe-Universitat in Frankfurt, Germany, analyzed all known data on cryptic animal species and discovered that they are found in equal proportions throughout all major branches of the animal kingdom and occur in equal numbers in all biogeographical regions.Scientists had previously speculated that cryptic species were predominantly found in insects and reptiles, and were more likely to occur in tropical rather than temperate regions. “Species that are seemingly widespread and abundant could in reality be many different Cryptic species that have low populations and are highly endangered," says Pfenninger. Until the genetic information of all species in at least one taxon is thoroughly studied, no one will know just how many cryptic species exist, "It could be as high as 30%, Pfenninger says."I'm extremely surprised by their results," says Alex Smith of the University of Guelph in Ontario, Canada. "It's a call to arms to keep doing the broad kind of genetic studies that we are doing. "Sampling as many individuals as possible, scientists hope to complete. work on all fish and birds in another 5 to 10 years. Once either of these taxonomic groups is completed, Pfenninger says researchers will be able to decide how many cryptic species exist throughout the animal kingdom.Examples of cryptic species include the African elephant. A 2001 study found the elephants were actually two genetically distinct, non-interbreeding species, the African bush elephant and the African elephant. The species are currently listed as vulnerable and threatened, respectively, by the World Conservation Union (WCU).The reclassifications are more than an academic exercise. They define populations that have evolved independently of each other and whose genetic differences can have significant consequences.In the early 1900s misidentification of mosquito species based on morphology confused: attempts to control malaria in Europe. Ultimately, what was thought to be a single species was actually made up of six sibling species, only three of which transmitted the disease. "The basic unit in biology is always the species, and you have to know what you are dealing with," Pfenninger says. Much previous research is now no longer used, he Says, because it is not clear what species was being studied.练习：1. Which of the following about the significance of the research on cryptic species is NOT true?A The results of the research can help the development of many other research areas.B The results of the research can help the development of biodiversity estimates.C The results of the research can help our understanding of infectious disease evolution.D The results of the research can help our understanding of "survival of the fittest.

Either way, it involves water—or rather the lack of it.In Western Europe or the US, you only have to turn on the tap and you’ll see a jet of cold water, ready to drink, cook and bathe in, or wash the car. Turn o n the tap in Karachi and you’ll be lucky to fill a few buckets. Until 1947 the city was part of British India, whose engineers built and maintained a modest water supply network for the city’s 500,000 inhabitants. Today, Karachi is home to around 12 million people. Half of them live in slum townships, with little or no water through the mains. Even the rich half usually have to wait days before anything tickles through their pipes. And the coloured liquid that finally emerges is usually too contaminated to drink.Half usually have to wait days before anything tickles through their pipes. And the coloured liquid that finally emerges is usually too contaminated to drink.According to the state-owned Karachi Water and Sewerage Board, the city needs more than 2,500 million litres of water each day. The board currently supplies 1,650 million litres of which nearly 40 per cent is lost from leaks—and theft. Leaks are dime a dozen to water utilities the world over, but theft?Karachi’s unlikely water pirates turn o ut to be ordinary families struggling to get adequate supplies of one of life’s necessities. Stealing water takes many forms. The simplest is to buy a suction pump and get it attached to the water pipe that feeds your house from the mains. This should maximize your share of water every time the board switches on the supply. When the practice started 20 years ago, the pumps would be carefully hidden or disguised as garden ornaments. These days people hardly bother. The pumps are so widespread and water board inspectors so thin on the ground that when officials do confiscate a pump its owner simply buy a replacement.Insisting that people obey the law won’t work because most households have littlealternative but to steal. For its part, the Karachi Water and Sewerage Board says it would dearly like to make life easier, but finds itself mired in debt because most residents either won’t pay water charges or can’t afford to the Urban Resource Centre, a Karachi-based think tank, of the 1.2 million known consumers of water only 750,000 are billed, of whom just 163,000 actually pay for their supplies. The board makes a perpetual loss, and there is no money to improve the system or even plug the leaks. Worse, the board increasingly relies on international loans from institutions such as the Asian Development Bank, which only makes its debt worse.The joke is that the owners of the suction pumps end up with little—if any—extra water. Your house is in a line with 20 other households all tapping into one horizontal pipeline. All you can end up doing, given you have pumps of equal strength, is redistribute each other’s entitlement and pay higher electricity bills into the bargain.Back home in London, I’ll remember not to complain about the water meter, or the hosepipe ban.练习：1．According to the passage, people in Karachi today suffer from a short supply of water becauseA. the water supply network built in 1947 has stopped to function.B. the city has become much larger than before.C. old networks can not meet the need of the city’s greatly-increased population.D. other city is longer a part of British India.2. Now people in Karachi do not hide or disguise the suction pumps they use to steal water becauseA. the pumps are no longer wanted as garden ornaments.B. water supply board officials no longer confiscate them.C. it does not cost much money to buy a new one.D. many households have them and there are very few inspectors around to try to find them.3. Confronted with a severe shortage of water supply, the city’s Water and Sewerage BoardA. tries to improve the water supply system with borrowed money.B. is not making any effort to improve the situation.C. urges the consumers to obey the law.D. charges the consumers more for the water they use.4.Which of the following is true of the owners of the suction pumps, if their neighbors have equally powerful pumps as they do?A. They get some extra water.B. They only pay more for electricity.C. They share what they can get with their neighbors.D. They replace their pumps with new ones.5. Which of the following is true about the author when he is back home in London?A. He misses the days he spent in Karachi.B. He forgets the complaints he made in Karachi.C. He is content with the water supply in London.D. he complains about the water supply in London.。

They’re all disease caused by viruses，tiny microorganisms that can pass from person to person．It's no wonder that when most people think about viruses, finding ways t0 steer clear of viruses is what's on people's minds．Not everyone runs from the tiny disease carders, though．In Cambridge, Massachusetts, scientists have discovered that some viruses can be helpful in an unusual way．They are putting viruses to work, teaching them to build some of the world's smallest rechargeable batteries.Viruses and batteries may seem like an unusual pair，but they're not so strange for engineer Angela Belcher，who first came up with the idea．At the Massachusetts Institute of Technology (MIT) in Cambridge, she and her collaborators bring together different areas of science in new ways．In the case of the virus-built batteries, the scientists combine what they know about biology, technology and production techniques．Belcher's team includes Paula Hammond，who helps put together the tiny batteries, and Yet-Ming Chiang，an expert on how to store energy in the form of a battery．“We’re working on things we traditionally don’t associate with nature．”says Hammond.Many batteries are already pretty small．You can hold A．C and D batteries in your hand．The coin—like batteries that power watches are often smaller than a penny．However。
