雅思剑桥15text2阅读The IELTS Cambridge 15 Text 2 Reading passage is titled "The effects of light on plant and animal species." This passage discusses the impact of artificial light on various organisms and ecosystems. It explores how light pollution affects plants, animals, and humans, and provides insights into the measures that can be taken to mitigate these effects.The passage begins by explaining that artificial light at night disrupts the natural light-dark cycle that organisms have evolved to rely on. This disruption can have detrimental effects on both plants and animals. For example, excessive light can interfere with the growth and development of plants, leading to reduced crop yields and changes in plant behavior. It can also disrupt the behavior and reproductive patterns of animals, affecting their feeding habits, migration, and mating rituals.Furthermore, light pollution can have indirect effects on ecosystems. For instance, it can alter the behavior of nocturnal animals, making them more vulnerable to predation or causing them to abandon their habitats. This disruption can have cascading effects on the entire food chain, impacting other species that depend on these nocturnal animals for food or other ecological services.In addition to its impact on plants and animals, artificial light at night can also affect human health. The passage highlights that exposure to bright light at night can disrupt the production of melatonin, a hormone that regulates sleep-wake cycles. This disruption can lead to sleep disorders, such as insomnia, and increase the risk of various health problems, including obesity, diabetes, and certain types of cancer.To mitigate the negative effects of light pollution, the passage suggests several measures that can be taken. These include using outdoor lighting fixtures that direct light downward and minimize light spillage, implementing lighting curfews or dimming lights during certain hours, and creating designated dark sky areas where artificial light is limited. These measures aim to reduce the amount of artificial light that escapes into the environment and minimize its impact on organisms and ecosystems.In conclusion, the IELTS Cambridge 15 Text 2 Reading passage discusses the effects of artificial light on plant and animal species. It highlights the negative consequences of light pollution on plants, animals, and human health. The passage also suggests various measures that can be taken to mitigate these effects, emphasizing the importance of responsible outdoor lighting practices and the creation of dark sky areas. By understanding and addressing the impacts of light pollution, we can strive to protect and preserve the natural light-dark cycles that are essential for the well-being of all organisms.。

2015年7月23日雅思考试阅读真题Passage 2:题目:Finding our way内容:人类行为的研究题型:配对题5道,选择题3道,判断题5道题号:V100529Finding Our WayA “Drive 200 yards, and then turn right, “says the car’s computer voice. You relax in the driver’s seat, follow the directions and reach your destination without error. It’s certainly nice to have the Global Positioning System (GPS) to direct you to within a few yards of your goal. Yet if the satellite service’s digital maps become even slightly outdated, you can become lost. Then you have to rely on the ancient human skill of navigating 航行in three-dimensional space. Luckily, your biological finder生物探测器/发现者has an important advantage over GPS: it does not go awry失败/出错if only one part of the guidance system goes wrong, because it works in various ways. You can ask questions of people on the sidewalk. Or follow a street that looks familiar. Or rely on a navigational rubric红色标志: "If I keep the East River on my left, I will eventually cross 34th Street.” The human positioning system is flexible and capable of learning. Anyone who knows the way from point A to point B—and from A to C—can probably figure out how to get fromB to C, too.B But how does this complex cognitive认知system really work? Researchers are looking at several strategies people use to orient 向东themselves in space: guidance, path integration and route following. We may use all three or combinations thereof在其中. And as experts learn more about these navigational skills, they are making the case that our abilities may underlie在什么基础下our powers of memory and logical thinking. Grand Central中央车站, Please Imagine that you have arrived in a place you have never visited—New York City. You get off the train at Grand Central Terminal in midtown Manhattan. You have a few hours to explore before you must return for your ride home. You head uptown to see popular spots you have been told about: Rockefeller Center洛克菲勒中心, Central Park, and the Metropolitan Museum of Art大都会博物馆. You meander 漫步in and out of shops along the way. Suddenly, it is time to get back to the station. But how?C If you ask passersby for help, most likely you will receive information in many different forms. A person who orients herself by a prominent landmark would gesturesouthward: "Look down there. See the tall, broad MetLife Building? Head for that—the station is right be low it. “Neurologists call this navigational approach "guidance,” meaning that a landmark visible from a distance serves as t he marker for one’s destination.D Another city dweller居民might say: "What places do you remember passing? . . . Okay. Go toward the end of Central Park, then walk down to St. Patrick’s Cathedral大教堂.A few more blocks, and Grand Central will be off to yo ur left. “In this case, you are pointed toward the most recent place you recall, and you aim for it. Once there you head for the next notable place and so on, retracing折回your path. Your brain is adding together the individual legs of your trek艰难跋涉into a cumulative积累的progress report. Researchers call this strategy "path integration.”路劲整合Many animals rely primarily on path integration to get around, including insects, spiders, crabs and rodents啮齿动物. The desert ants of the genus类Cataglyphis 沙蚁employ this method to return from foraging觅食as far as 100 yards away. They note the general direction they came from and retrace their steps, using the polarization极化of sunlight to orient themselves even under overcast skies阴暗的天空. On their way back they are faithful to this inner homing vector航线. Even when a scientist picks up an ant and puts it in a totally different spot, the insect stubbornly proceeds in the originally determined direction until it has gone "back" all of the distance it wandered from its nest. Only then does the ant realize it has not succeeded, and it begins to walk in successively larger loops循环to find its way home.E Whether it is trying to get back to the anthill or the train station, any animal using path integration must keep track of its own movements so it knows, while returning, which segments it has already completed. As you move, your brain gathers data from your environment—sights, sounds, smells, lighting, muscle contractions收缩, a sense of time passing—to determine which way your body has gone. The church spire尖塔, the sizzling 极热的sausages香肠on that vendor’s grill小贩的架子, the open courtyard庭院, and the train station—all represent snapshots快照of memorable junctures 连接during your journey.F In addition to guidance and path integration, we use a third method for finding our way. An office worker you approach for help on a Manhattan street comer might say: "Walk straight down Fifth, turn left on 47th, turn right on Park, go through the walkway under the Helmsley Building, then cross the stree t to the MetLife Building into Grand Central.” This strategy, called route following, uses landmarks such as building sand street names, plus directions—straight, turn, go through—for reaching intermediate中间点points. Route following is more precise than guidance or path integration, but if you forget the details and take a wrong turn, the only way to recover is to backtrack until you reach a familiar spot, because you do not know the general direction or have a reference landmark for your goal. The route-following navigation strategy truly challenges the brain. We have to keep all the landmarks and intermediate directions in our head. It is the most detailed and therefore most reliable method, but it can be undone by routine memory lapses记忆差错. With path integration, our cognitive memory is less burdened负担大; it has to deal with only a few general instructions and the homing vector. Path integration works because it relies most fundamentally on our knowledge of our body’s general direction o f movement, and we always have access to these inputs. Nevertheless, people often choose to give route- following directions, in part because saying "Go straight that way!" just does notwork in our complex, man- made surroundings.G Road Map or Metaphor隐喻? On your next visit to Manhattan you will rely on your memory to get around. Most likely you will use guidance, path integration and route following in various combinations. But how exactly do these constructs构图deliver concrete directions? Do we humans have, as an image of the real world, a kind of road map in our heads—with symbols for cities, train stations and churches; thick粗线lines for highways; narrow lines for local streets? Neurobiologists and cognitive psychologists do call the portion部分of our memory that controls navigation a "cognitive map.” The map metaphor is obviously seductive引人注意的: maps are the easiest way to present geographic information for convenient visual inspection. In many cultures, maps were developed before writing, and today they are used in almost every society. It is even possible that maps derive from a universal way in which our spatial空间的-memory networks are wired接电线的.H Yet the notion of a literal map in our heads may be misleading; a growing body of research implies that the cognitive map is mostly a metaphor. It may be more like a hierarchical层级structure of relationships.To get back to Grand Central, you first envision (想象) the large scale—that is, you visualize the general direction of the station. Within that system you then imagine the route to the last place you remember. After that, you observe your nearby surroundings to pick out a recognizable可辨认的storefront店面or street comer that will send you toward that place. In this hierarchical, or nested, scheme, positions and distances are relative, in contrast with a road map, where the same information is shown in a geometrically几何学上的precise scale.Questions 14-18Use the information in the passage to match the category of each navigation method (listed A-C) with correct statement. Write the appropriate letters A-C in boxes 14-18on your answer sheet.NB you may use any letter more than onceA GuidanceB Path integration.C Route following14 Using basic direction from starting point and light intensity强度to move on. B15 Using combination of place and direction heading for destination. C16 Using an iconic标志性building near your destination as orientation.

BQuestions 19-21Choose the correct letter, A, B, C or D.Write your answers in boxes 19-21 on your answer sheet.19 What does the ant of Cataglyphis respond if it has been taken to another location according to the passage?A Changes the orientation sensors感应improvinglyB Releases biological scent气味for help from othersC Continues to move by the original orientationD totally gets lost once disturbed20 Which of the followings is true about "cognitive map" in this passage?A There is not obvious difference contrast by real mapB It exists in our head and is always correctC It only exists under some culturesD It was managed by brain memory21 Which of following description of way findings correctly reflects the function of cognitive map?A It visualizes a virtual route in a large scopeB It reproduces an exact details of every landmarkC Observation plays a more important roleD Store or supermarket is a must in the mapQuestions 22-26Do the following statements agree with the information given in Reading Passage 2?

2015考研英语阅读理解精读P2—法学类

2015考研英语阅读理解精读P2—法学类

2015考研英语阅读理解精读P2—法学类Passage 2(Stricter Traffic Law can Prevent Accidents)From the health point of view we are living in a marvelous age. We are immunized from birth against many of the most dangerous diseases. A large number of once fatal illnesses can now be cured by modern drugs and surgery. It is almost certain that one day remedies will be found for the most stubborn remaining diseases. The expectation of life has increased enormously. But though the possibility of living a long and happy life is greater than ever before, every day we witness the incredible slaughter of men, women and children on the roads. Man versus the motor-car ! It is a never-ending battle which man is losing. Thousands of people the world over are killed or horribly killed each year and we are quietly sitting back and letting it happen.It has been rightly said that when a man is sitting behind a steering wheel, his car becomes the extension of his personality. There is no doubt that the motor-car often brings out a man’s very worst qualities. People who are normally quiet and pleasant may become unrecognizable when they are behind a steering-wheel. They swear, they are ill-mannered and aggressive, willful as two-years-olds and utterly selfish. All their hidden frustrations, disappointments and jealousies seem to be brought to the surface by the act of driving.The surprising thing is that society smiles so benignly on the motorist and seems to condone his behaviour. Everything is done for his convenience. Cities are allowed to become almost uninhabitable because of heavy tragic; towns are made ugly by huge car parks; the countryside is desecrated by road networks; and the mass annual slaughter becomes nothing more than a statistic, to be conveniently forgotten.It is high time a world code were created to reduce this senseless waste of human life. With regard to driving, the laws of some countries are notoriously lax and even the strictest are not strict enough. A code which was universally accepted could only have a dramatically beneficial effect on the accident rate. Here are a few examples of some the things that might be done. The driving test should be standardized and made far more difficult than it is; all the drivers should be made to take a test every three years or so; the age at which young people are allowed to drive any vehicle should be raised to at least 21; all vehicles should be put through stringent annual tests for safety. Even the smallest amount of alcohol in the blood can impair a person’s driving ability. Present drinking and driving laws (where they exist) should be mad much stricter. Maximum and minimum speed limits should be imposed on all roads. Governments should lay down safety specifications for manufacturers, as has been done in the USA. All advertising stressing power and performance should be banned. These measures may sound inordinately harsh. But surely nothing should be considered as too severe if tit results in reducing the annual toll of human life. After all, the world is for human beings, not motor-cars.1.The main idea of this passage is[A] Traffic accidents are mainly caused by motorists.[B] Thousands of people the world over are killed each year.[C] The laws of some countries about driving are too lax.[D] Only stricter traffic laws can prevent accidents.2.What does the author think of society toward motorists?[A] Society smiles on the motorists.[B] Huge car parks are built in the cities and towns.[C] Victims of accidents are nothing.[D] Society condones their rude driving.3.Why does the author say:’his car becomes the extension of his personality?’[A] Driving can show his real self.[B] Driving can show the other part of his personality.[C] Driving can bring out his character.[D] His car embodies his temper.4.Which of the followings is NOT mentioned as a way against traffic accidents?[A] Build more highways.[B] Stricter driving tests.[C] Test drivers every three years.[D] raise age limit and lay down safety specifications.5.The attitude of the author is[A] ironical[B] critical[C] appealing[D] militantVocabulary1.immunise 使免疫,使免除2.expectation of life = life expectancy 平均寿命3.versus = against 对顶,反对4.mutilate 伤害5.wilful 任性的,固执的6.benign 宽厚的,仁慈的7.condone 宽容8.desecrate 亵渎,玷污9.code 法规,规定,惯例10.stringent 严格的,紧急的,迫切的11.performance 演出,成品,这里是指car’s behavior such as speed, function etc.可译成行为,汽车行为、功能等。

剑桥雅思真题15-阅读Test 4(附答案)

剑桥雅思真题15-阅读Test 4(附答案)READING PASSAGE 1You should spend about 20 minutes on Questions 1–13, which are based on Reading Passage 1 below.The return of the huarangoThe arid valleys of southern Peru are welcoming the return of a native plantThe south coast of Peru is a narrow, 2,000-kilometre-long strip of desert squeezed between the Andes and the Pacific Ocean. It is also one of the most fragile ecosystems on Earth. It hardly ever rains there, and the only year-round source of water is located tens of metres below the surface. This is why the huarango tree is so suited to life there: it has the longest roots of any tree in the world. They stretch down 50-80 metres and, as well as sucking up water for the tree, they bring it into the higher subsoil, creating a water source for other plant life.Dr David Beresford-Jones, archaeobotanist at Cambridge University, has been studying the role of the huarango tree in landscape change in the Lower lea Valley in southern Peru. He believes the huarango was key to the ancient people's diet and, because it could reach deep water sources, it allowed local people to withstand years of drought when their other crops failed. But over the centuries huarango trees were gradually replaced with crops. Cutting down native woodland leads to erosion, as there is nothing to keep the soil in place. So when the huarangos go, the land turns into a desert. Nothing grows at all in the Lower lea Valley now.For centuries the huarango tree was vital to the people of the neighbouring Middle lea Valley too. They grew vegetables under it and ate products made from its seed pods. Its leaves and bark were used for herbal remedies, while its branches were used for charcoal for cooking and heating, and its trunk was used to build houses. But now it is disappearing rapidly. The majority of the huarango forests in the valley have already been cleared for fuel and agriculture - initially, these were smallholdings, but now they're huge farms producing crops for the international market.'Of the forests that were here 1,000 years ago, 99 per cent have already gone,' says botanist Oliver Whaley from Kew Gardens in London, who, together with ethnobotanist Dr William Milliken, is running a pioneering project to protect and restore the rapidly disappearing habitat. In order to succeed, Whaley needs to get the local people on board, and that has meant overcoming local prejudices. 'Increasingly aspirational communities think that if you plant food trees in your home or street, it shows you are poor, and still need to grow your own food,' he says. In order to stop the Middle lea Valley going the same way as the Lower lea Valley, Whaley is encouraging locals to love the huarangos again. 'It's a process of cultural resuscitation,' he says. He has already set up a huarango festival to reinstate a sense of pride in their eco-heritage, and has helped local schoolchildren plant thousands of trees.'In order to get people interested in habitat restoration, you need to plant a tree that is useful to them,' says Whaley. So, he has been working with local families to attempt to create a sustainable income from the huarangos by turning their products into foodstuffs. 'Boil up the beans and you get this thick brown syrup like molasses. You can also use it in drinks, soups or stews. ' The pods can be ground into flour to make cakes, and the seeds roasted into a sweet, chocolatey 'coffee'. 'It's packed full of vitamins and minerals, ' Whaley says.And some farmers are already planting huarangos. Alberto Benevides, owner of lea Valley's onlycertified organic farm, which Whaley helped set up, has been planting the tree for 13 years. He produces syrup and flour, and sells these products at an organic farmers' market in Lima. His farm is relatively small and doesn't yet provide him with enough to live on, but he hopes this will change. 'The organic market is growing rapidly in Peru, ' Benevides says. 'I am investing in the future.But even if Whaley can convince the local people to fall in love with the huarango again, there is still the threat of the larger farms. Some of these cut across the forests and break up the corridors that allow the essential movement of mammals, birds and pollen up and down the narrow forest strip. In the hope of counteracting this, he's persuading farmers to let him plant forest corridors on their land. He believes the extra woodland will also benefit the farms by reducing their water usage through a lowering of evaporation and providing a refuge for bio-control insects.'If we can record biodiversity and see how it all works, then we're in a good position to move on from there. Desert habitats can reduce down to very little, ' Whaley explains. 'It's not like a rainforest that needs to have this huge expanse. Life has always been confined to corridors and islands here. If you just have a few trees left, the population can grow up quickly because it's used to exploiting water when it arrives? He sees his project as a model that has the potential to be rolled out across other arid areas around the world. 'If we can do it here, in the most fragile system on Earth, then that's a real message of hope for lots of places, including Africa, where there is drought and they just can't afford to wait for rain.'Questions 1-5Complete the notes below.Choose ONE WORD ONLY from the passage for each answer.Complete the table below.Choose NO MORE THAN TWO WORDS from the passage for each answer.Questions 9-13Do the following statements agree with the information given in Reading Passage 1?In boxes 9-13 on your answer sheet, writeTRUE if the statement agrees with the informationFALSE if the statement contradicts the informationNOT GIVEN if there is no information on this9 Local families have told Whaley about some traditional uses of huarango products.10 Farmer Alberto Benevides is now making a good profit from growing huarangos.11 Whaley needs the co-operation of farmers to help preserve the area's wildlife.12 For Whaley's project to succeed, it needs to be extended over a very large area.13 Whaley has plans to go to Africa to set up a similar project.READING PASSAGE 2You should spend about 20 minutes on Questions 13–26, which are based on Reading Passage 2 below.Silbo Gomero-the whistle ‘language’ of the Canary IslandsLa Gomera is one of the Canary Islands situated in the Atlantic Ocean off the northwest coast of Africa. This small volcanic island is mountainous, with steep rocky slopes and deep, wooded ravines, rising to 1,487 metres at its highest peak. It is also home to the best known of the world's whistle 'languages', a means of transmitting information over long distances which is perfectly adapted to the extreme terrain of the island.This 'language', known as 'Silbo' or 'Silbo Gomero' - from the Spanish word for 'whistle'- is now shedding light on the language-processing abilities of the human brain, according to scientists. Researchers say that Silbo activates parts of the brain normally associated with spoken language, suggesting that the brain is remarkably flexible in its ability to interpret sounds as language.'Science has developed the idea of brain areas that are dedicated to language, and we are starting to understand the scope of signals that can be recognised as language,' says David Corina, co-author of a recent study and associate professor of psychology at the University of Washington in Seattle.Silbo is a substitute for Spanish, with individual words recoded into whistles which have high- and low-frequency tones. A whistler - or silbador - puts a finger in his or her mouth to increase the whistle's pitch, while the other hand can be cupped to adjust the direction of the sound. 'There is much more ambiguity in the whistled signal than in the spoken signal/ explains lead researcher Manuel Carreiras, psychology professor at the University of La Laguna on the Canary island of Tenerife. Because whistled 'words' can be hard to distinguish, silbadores rely on repetition, as well as awareness of context, to make themselves understood.The silbadores of Gomera are traditionally shepherds and other isolated mountain folk, and their novel means of staying in touch allows them to communicate over distances of up to 10 kilometres. Carreiras explains that silbadores are able to pass a surprising amount of information via their whistles. 4In daily life they use whistles to communicate short commands, but any Spanish sentence could be whistled.5 Silbo has proved particularly useful when fires have occurred on the island and rapid communication across large areas has been vital.The study team used neuroimaging equipment to contrast the brain activity of silbadores while listening to whistled and spoken Spanish. Results showed the left temporal lobe of the brain, which is usually associated with spoken language, was engaged during the processing of Silbo. The researchers found that other key regions in the brain's frontal lobe also responded to the whistles, including those activated in response to sign language among deaf people. When the experiments were repeated with non-whistlers, however, activation was observed in all areas of the brain.'Our results provide more evidence about the flexibility of human capacity for language in a variety of forms' Corina says. 'These data suggest that left-hemisphere language regions are uniquely adapted for communicative purposes, independent of the modality of signal. The non-Silbo speakers were not recognising Silbo as a language. They had nothing to grab onto, so multiple areas of their brains were activated?Carreiras says the origins of Silbo Gomero remain obscure, but that indigenous Canary Islanders, who were of North African origin, already had a whistled language when Spain conquered the volcanic islands in the 15th century. Whistled languages survive today in Papua New Guinea, Mexico, Vietnam, Guyana, China, Nepal, Senegal, and a few mountainous pockets in southern Europe. There are thought to be as many as 70 whistled languages still in use, though only 12 have been described and studied scientifically. This form of communication is an adaptation found among cultures where people are often isolated from each other, according to Julien Meyer, a researcher at the Institute of Human Sciences in Lyon, France. 'They are mostly used in mountains or dense forests, ' he says. 'Whistled languages are quite clearly defined and represent an original adaptation of the spoken language for the needs of isolated human groups?But with modern communication technology now widely available, researchers say whistled languages like Silbo are threatened with extinction. With dwindling numbers of Gomera islanders still fluent in the language, Canaries' authorities are taking steps to try to ensure its survival. Since 1999, Silbo Gomero has been taught in all of the island's elementary schools. In addition, locals are seeking assistance from the United Nations Educational, Scientific and Cultural Organization (UNESCO). {The local authorities are trying to get an award from the organisation to declare [Silbo Gomero] as something that should be preserved for humanity,' Carreiras adds.Questions 14-19Do the following statements agree with the information given in Reading Passage 2?In boxes 14-19 on your answer sheet, writeTRUE if the statement agrees with the informationFALSE if the statement contradicts the informationNOT GIVEN if there is no information on this14 La Gomera is the most mountainous of all the Canary Islands.15 Silbo is only appropriate for short and simple messages.16 In the brain-activity study, silbadores and non-whistlers produced different results.17 The Spanish introduced Silbo to the islands in the 15th century.18 There is precise data available regarding all of the whistle languages in existence today.19 The children of Gomera now learn Silbo.Questions 20-26Complete the notes below.Choose ONE WORD ONLY from the passage for each answer.You should spend about 20 minutes on Questions 27–40, which are based on Reading Passage 3 below.Environmental practices of big businessThe environmental practices of big businesses are shaped by a fundamental fact that for many of us offends our sense of justice. Depending on the circumstances, a business may maximize the amount of money it makes, at least in the short term, by damaging the environment and hurting people. That is still the case today for fishermen in an unmanaged fishery without quotas, and for international logging companies with short-term leases on tropical rainforest land in places with corrupt officials and unsophisticated landowners. When government regulation is effective, and when the public is environmentally aware, environmentally clean big businesses may out-compete dirty ones, but the reverse is likely to be true if government regulation is ineffective and if the public doesn't care.It is easy for the rest of us to blame a business for helping itself by hurting other people. But blaming alone is unlikely to produce change. It ignores the fact that businesses are not charities but profit-making companies, and that publicly owned companies with shareholders are under obligation to those shareholders to maximize profits, provided that they do so by legal means. US laws make a company's directors legally liable for something termed 'breach of fiduciary responsibility' if they knowingly manage a company in a way that reduces profits. The car manufacturer Henry Ford was in fact successfully sued by shareholders in 1919 for raising the minimum wage of his workers to $5 per day: the courts declared that, while Ford's humanitarian sentiments about his employees were nice, his business existed to make profits for its stockholders.Our blaming of businesses also ignores the ultimate responsibility of the public for creating the conditions that let a business profit through destructive environmental policies. In the long run, it is the public, either directly or through its politicians, that has the power to make such destructive policies unprofitable and illegal, and to make sustainable environmental policies profitable.The public can do that by suing businesses for harming them, as happened after the Exxon Valdez disaster, in which over 40,000 m3 of oil were spilled off the coast of Alaska. The public may also make their opinion felt by preferring to buy sustainably harvested products; by making employees of companies with poor track records feel ashamed of their company and complain to their own management; by preferring their governments to award valuable contracts to businesses with a good environmental track record; and by pressing their governments to pass and enforce laws and regulations requiring good environmental practices.In turn, big businesses can exert powerful pressure on any suppliers that might ignore public or government pressure. For instance, after the US public became concerned about the spread of a disease known as BSE, which was transmitted to humans through infected meat, the USgovernment's Food and Drug Administration introduced rules demanding that the meat industry abandon practices associated with the risk of the disease spreading. But for five years the meat packers refused to follow these, claiming that they would be too expensive to obey. However, when a major fast-food company then made the same demands after customer purchases of its hamburgers plummeted, the meat industry complied within weeks. The public's task is therefore to identify which links in the supply chain are sensitive to public pressure: for instance, fast-food chains or jewelry stores, but not meat packers or gold miners.Some readers may be disappointed or outraged that I place the ultimate responsibility for business practices harming the public on the public itself. I also believe that the public must accept the necessity for higher prices for products to cover the added costs, if any, of sound environmental practices. My views may seem to ignore the belief that businesses should act in accordance with moral principles even if this leads to a reduction in their profits. But I think we have to recognize that, throughout human history, in all politically complex human societies, government regulation has arisen precisely because it was found that not only did moral principles need to be made explicit, they also needed to be enforced.To me, the conclusion that the public has the ultimate responsibility for the behavior of even the biggest businesses is empowering and hopeful, rather than disappointing. My conclusion is not a moralistic one about who is right or wrong, admirable or selfish, a good guy or a bad guy. In the past, businesses have changed when the public came to expect and require different behavior, to reward businesses for behavior that the public wanted, and to make things difficult for businesses practicing behaviors that the public didn't want. I predict that in the future, just as in the past, changes in public attitudes will be essential for changes in businesses' environmental practices.

剑雅15test2大作文范文英文回答:With more and more people choosing to live in densely populated cities, the strain on infrastructure, resources, and the environment has become increasingly evident. Urbanization has brought about a host of challenges, ranging from traffic congestion and air pollution to a lack of affordable housing and green spaces. While these issues are undoubtedly complex, there are a number of innovative and sustainable solutions that can be implemented to mitigate their impact and improve urban living.One of the most pressing challenges facing cities is the issue of traffic congestion. With more people living and working in urban areas, the number of vehicles on the road has increased exponentially, leading to longer commute times, increased emissions, and a decline in air quality. To address this problem, cities can implement a variety of measures, such as investing in public transportation,promoting carpooling and ride-sharing, and creating dedicated bike lanes and pedestrian walkways. By providing more efficient and sustainable transportation options,cities can reduce the number of vehicles on the road, ease traffic congestion, and improve air quality.Another major challenge facing cities is the issue ofair pollution. Urban areas are often home to a high concentration of vehicles, industries, and other sources of air pollution, which can have a detrimental impact on the health of residents. To mitigate this problem, cities can implement a number of measures, such as promoting the useof electric vehicles, investing in renewable energy sources, and implementing green building codes. By reducing the amount of air pollution, cities can improve the health of their residents and create a more sustainable environment.The lack of affordable housing is another major challenge facing cities. With rising housing costs, many people are struggling to find a place to live that they can afford. To address this problem, cities can implement a variety of measures, such as increasing the supply ofaffordable housing, providing rent subsidies, and offering homeownership assistance programs. By making housing more affordable, cities can ensure that everyone has a place to live, regardless of their income.The lack of green spaces is another major challenge facing cities. Urban areas are often lacking in green spaces, such as parks, gardens, and open spaces, which can have a negative impact on the physical and mental health of residents. To address this problem, cities can implement a variety of measures, such as creating new parks and green spaces, planting trees, and converting unused land into green spaces. By increasing the amount of green spaces, cities can improve the health of their residents and create a more sustainable environment.In conclusion, while urbanization has brought about a host of challenges, there are a number of innovative and sustainable solutions that can be implemented to mitigate their impact and improve urban living. By investing in public transportation, promoting carpooling and ride-sharing, creating dedicated bike lanes and pedestrianwalkways, promoting the use of electric vehicles, investing in renewable energy sources, implementing green building codes, increasing the supply of affordable housing, providing rent subsidies, offering homeownership assistance programs, creating new parks and green spaces, planting trees, and converting unused land into green spaces, cities can address the challenges of urbanization and create more sustainable and livable urban environments.中文回答:随着越来越多的人选择居住在人口稠密的城市,基础设施、资源和环境所承受的压力变得越来越明显。

托福阅读 15-2 Mass Extinctions

托福阅读 15-2 Mass Extinctions

Mass ExtinctionsCases in which many species become extinct within a geologically short interval of time are called mass extinctions. There was one such event at the end of the Cretaceous period (around 70 million years ago). There was another, even larger, mass extinction at the end of the Permian period (around 250 million years ago). The Permian event has attracted much less attention than other mass extinctions because mostly unfamiliar species perished at that time.The fossil record shows at least five mass extinctions in which many families of marine organisms died out. The rates of extinction happening today are as great as the rates during these mass extinctions. Many scientists have therefore concluded that a sixth great mass extinction is currently in progress.What could cause such high rates of extinction? There are several hypotheses, including warming or cooling of Earth, changes in seasonal fluctuations or ocean currents, and changing positions of the continents. Biological hypotheses include ecological changes brought about by the evolution of cooperation between insects and flowering plants or of bottom-feeding predators in the oceans. Some of the proposed mechanisms required a very brief period during which all extinctions suddenly took place; other mechanisms would be more likely to have taken place more gradually, over an extended period, or at different times on different continents. Some hypotheses fail to account for simultaneous extinctions on land and in the seas. Each mass extinction may have had a different cause. Evidence points to hunting by humans and habitat destruction as the likely causes for the current mass extinction.American paleontologists David Raup and John Sepkoski, who have studied extinction rates in a number of fossil groups, suggest that episodes of increased extinction have recurred periodically, approximately every 26 million years since the mid-Cretaceous period. The late Cretaceous extinction of the dinosaurs and ammonoids was just one of the more drastic in a whole series of such recurrent extinction episodes. The possibility that mass extinctions may recur periodically has given rise to such hypotheses as that of a companion star with a long-period orbit deflecting other bodies from their normal orbits, making some of them fall to Earth as meteors and causing widespread devastation upon impact.Of the various hypotheses attempting to account for the late Cretaceous extinctions, the one that has attracted the most attention in recent years is the asteroid-impact hypothesis first suggested by Luis and Walter Alvarez. According to this hypothesis, Earthcollided with an asteroid with an estimated diameter of 10 kilometers, or with several asteroids, the combined mass of which was comparable. The force of collision spewed large amounts of debris into the atmosphere, darkening the skies for several years before the finer particles settled. The reduced level of photosynthesis led to a massive decline in plant life of all kinds, and this caused massive starvation first of herbivores and subsequently of carnivores. The mass extinction would have occurred very suddenly under this hypothesis.One interesting test of the Alvarez hypothesis is based on the presence of the rare-earth element iridium (Ir). Earth’s crust contains very little of this element, but most asteroids contain a lot more. Debris thrown into the atmosphere by an asteroid collision would presumably contain large amounts of iridium, and atmospheric currents would carry this material all over the globe. A search of sedimentary deposits that span the boundary between the Cretaceous and Tertiary periods shows that there is a dramatic increase in the abundance of iridium briefly and precisely at this boundary. This iridium anomaly offers strong support for the Alvarez hypothesis even though no asteroid itself has ever been recovered.An asteroid of this size would be expected to leave an immense crater, even if the asteroid itself was disintegrated by the impact. The intense heat of the impact would produce heat-shocked quartz in many types of rock. Also, large blocks thrown aside by the impact would form secondary craters surrounding the main crater. To date, several such secondary craters have been found along Mexico’s Yucatan Peninsula, and heat-shocked quartz has been found both in Mexico and in Haiti. A location called Chicxulub, along the Yucatan coast, has been suggested as the primary impact site.Paragraph 1: Cases in which many species become extinct within a geologically short interval of time are called mass extinctions. There was one such event at the end of the Cretaceous period (around 70 million years ago). There was another, even larger, mass extinction at the end of the Permian period (around 250 million years ago). The Permian event has attracted much less attention than other mass extinctions because mostly unfamiliar species perished at that time.1. Paragraph 1 supports which of the following statements about mass extinctions?○They take place over a period of 70 million years.○They began during the Cretaceous period.○They eliminate many animal species that exist at the time they occur.○They occur every 250 million years.Paragraph 2: The fossil record shows at least five mass extinctions in which many families of marine organisms died out. The rates of extinction happening today are as great as the rates during these mass extinctions. Many scientists have therefore concluded that a sixth great mass extinction is currently in progress.2. According to paragraph 2, scientists base their belief that a mass extinction is going on at present on which of the following?○The speed with which mass extinctions are happening today is similar to the speed of past extinctions.○The number of species that have died out since the last extinction event is extremely large.○Mass extinctions occur with regularity and it is time for another one.○Fossil records of many marine species have disappeared.Paragraph 3: What could cause such high rates of extinction? There are several hypotheses, including warming or cooling of Earth, changes in seasonal fluctuations or ocean currents, and changing positions of the continents. Biological hypotheses include ecological changes brought about by the evolution of cooperation between insects and flowering plants or of bottom-feeding predators in the oceans. Some of the proposed mechanisms required a very brief period during which all extinctions suddenly took place; other mechanisms would be more likely to have taken place more gradually, over an extended period, or at different times on different continents. Some hypotheses fail to account for simultaneous extinctions on land and in the seas. Each mass extinction may have had a different cause. Evidence points to hunting by humans and habitat destruction as the likely causes for the current mass extinction.3. The word extended in the passage is closest in meaning to○ specific○ unlimited○ reasonable○ long4. According to paragraph 3, each of the following has been proposed as a possible cause of mass extinctions EXCEPT○habitat destruction○continental movement○fierce interspecies competition○changes in Earth's temperature5. Paragraph 3 supports which of the following ideas about mass extinctions?○Scientists know the exact causes of most mass extinctions.○Mass extinctions are unlikely to happen again in the future.○Insects, flowering plants, and bottom-feeding predators in the oceans tend to be the first organisms to disappear during episodes of mass extinctions.○Some mass extinctions occurred on land and in the seas at the same time.Paragraph 4: American paleontologists David Raup and John Sepkoski, who have studied extinction rates in a number of fossil groups, suggest that episodes of increased extinction have recurred periodically, approximately every 26 million years since the mid-Cretaceous period. The late Cretaceous extinction of the dinosaurs and ammonoids was just one of the more drastic in a whole series of such recurrent extinction episodes. The possibility that mass extinctions may recur periodically has given rise to such hypotheses as that of a companion star with a long-period orbit deflecting other bodies from their normal orbits, making some of them fall to Earth as meteors and causing widespread devastation upon impact.6. Which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.○Based on their studies of extinction rates of numerous fossil groups, paleontologists David Raup and John Sepkoski have determined that mass extinctions occur about every 26 million years.○David Raup and John Sepkoski studied extinction rates of numerous fossil groups and suggest that mass extinctions during the Cretaceous period continued for 26 million years.○Studies that paleontologists David Raup and John Sepkoski conducted of various fossil groups have revealed that extinction rates have increased over the past 26 million years.○The studies conducted by paleontologists David Raup and John Sepkoski of the fossil remains of species suggest that the extinction rate of species started to increase by the middle of the Cretaceous period.7. According to paragraph 4, what aspect of extinction episodes does the companion-star hypothesis supposedly clarify?○Their location○Their frequency○Their duration○Their severityParagraph 5: Of the various hypotheses attempting to account for the late Cretaceousextinctions, the one that has attracted the most attention in recent years is the asteroid-impact hypothesis first suggested by Luis and Walter Alvarez. According to this hypothesis, Earth collided with an asteroid with an estimated diameter of 10 kilometers, or with several asteroids, the combined mass of which was comparable. The force of collision spewed large amounts of debris into the atmosphere, darkening the skies for several years before the finer particles settled.

The mass extinction would have occurred very suddenly under this hypothesis.8. The phrase account for in the passage is closest in meaning to○describe○challenge○explain○testParagraph 6: One interesting test of the Alvarez hypothesis is based on the presence of the rare-earth element iridium (Ir). Earth’s crust contains very little of this element, but most asteroids contain a lot more. Debris thrown into the atmosphere by an asteroid collision would presumably contain large amounts of iridium, and atmospheric currents would carry this material all over the globe. A search of sedimentary deposits that span the boundary between the Cretaceous and Tertiary periods shows that there is a dramatic increase in the abundance of iridium briefly and precisely at this boundary. This iridium anomaly offers strong support for the Alvarez hypothesis even though no asteroid itself has ever been recovered.9. According to paragraph 6, what made iridium a useful test of the Alvarez hypothesis?○Its occurrence in a few locations on Earth against several locations on other planets○Its occurrence in limited quantities on Earth against its abundance in asteroids○Its ability to remain solid at extremely high temperatures○Its ease of detection even in very small amounts10. In stating that no asteroid itself has ever been recovered, the author emphasizes which of the following?○The importance of the indirect evidence for a large asteroid○The fact that no evidence supports the asteroidimpact hypothesis○The reason many researchers reject the Alvarez hypothesis○The responsibility of scientists for not making the effort to discover the asteroiditselfParagraph 7: An asteroid of this size would be expected to leave an immense crater, even if the asteroid itself was disintegrated by the impact. The intense heat of the impact would produce heat-shocked quartz in many types of rock. Also, large blocks thrown aside by the impact would form secondary craters surrounding the main crater. To date, several such secondary craters have been found along Mexico’s Yucatan Peninsula, and heat-shocked quartz has been found both in Mexico and in Haiti. A location called Chicxulub, along the Yucatan coast, has been suggested as the primary impact site.11. The word intense in the passage is closest in meaning to○ sudden○ unusual○ immediate○ extreme12. What is the purpose of paragraph 7 in the passage?○It proposes a decisive new test of the Alvarez hypothesis.○It presents additional supporting evidence for the Alvarez hypothesis.○It explains why evidence relating to the Alvarez hypothesis is hard to find.○It shows how recent evidence has raised doubts about the Alvarez hypothesis.Paragraph 1: ■Cases in which many species become extinct within a geologically short interval of time are called mass extinctions. ■There was one such event at the end of the Cretaceous period (around 70 million years ago). ■There was another, even larger, mass extinction at the end of the Permian period (around 250 million years ago). ■The Permian event has attracted much less attention than other mass extinctions because mostly unfamiliar species perished at that time.13. Look at the four squares [■] that indicate where the following sentence could be added to the passage.In general, it is believed that these two extinctions resulted from drastic environmental changes that followed meteorite impacts or massive volcanic eruptions.Where would the sentence best fit?14. Directions:An introductory sentence for a brief summary of the passage is provided below. Complete the summary by selecting the THREE answer choices thatexpress the most important ideas in the passage. Some sentences do not belong in the summary because they express ideas that are not presented in the passage or are minor ideas in the passage. This question is worth 2 points.There have been many attempts to explain the causes of mass extinctions.●●●Answer Choices○Asteroid impacts, evolutionary developments, and changes in Earth's climate and in the positions of the continents have all been proposed as possible causes of mass extinctions.○Researchers have observed 26-million-year cycles in extinction rates of a number of fossil groups that could all be attributed to the same cause.○According to the Alvarez hypothesis, much of the iridium originally present on Earth was thrown into the atmosphere as a result of an asteroid impact that also caused a mass extinction.○The unusual distribution of iridium on Earth and the presence of craters and heat-shocked quartz are central to the theory that an asteroid impact caused the late Cretaceous event.○The collision between Earth and a large asteroid resulted in massive damage and generated enough heat to cause irreversible changes in Earth's atmosphere.○There was a particularly large mass extinction that occurred around 250 million years ago at the end of the Permian period, whose cause could not be determined.参考答案:1. ○32. ○13. ○44. ○35. ○46. ○17. ○28.○39. ○210. ○111. ○412. ○213. ○414.

托福阅读真题第151篇TwoKindsofLizards

托福阅读真题第151篇TwoKindsofLizards

托福阅读真题第151篇TwoKindsofLizards第1段:蜥蜴按觅食方式可分为两种:静坐觅食型和主动型觅食型。

坐等蜥蜴通常呆在一个可以调查广阔区域的地方。

这些一动不动的蜥蜴目测昆虫的运动,并从观察点快速跑动捕捉它。

坐等蜥蜴可能最成功地检测和捕获相对较大的昆虫,如甲虫和鹅肝店员。

另一方面,活跃的觅食者大部分时间都在地面上度过,稳定地移动并将头从落叶下探入地下的裂缝中。

这些蜥蜴显然主要依靠化学线索来检测昆虫,它们可能会寻找局部集中的猎物,例如白蚁。

活跃的觅食者似乎比坐等捕食者的蜥蜴吃更多的昆虫。

因此,蜥蜴的不同觅食行为导致它们的饮食不同,即使两种蜥蜴出现在同一栖息地。

1. 根据第1 段,坐等式觅食者和主动式觅食者在以下所有方面都不同,除了O 他们主要用来检测昆虫的方法O 他们通常吃的昆虫数量O 可以找到它们的栖息地O 他们移动所花费的时间2. 根据第1 段,与坐等蜥蜴通常食用的昆虫相比,活动蜥蜴通常食用的昆虫O 移动得更快O 通常出现在较小的群体中O经常隐藏在视线之外O 花更多时间在地面上第2 段:不同的觅食方式对蜥蜴在暴露于捕食者方面也有不同的影响。

99% 的时间都在静止不动的蜥蜴相对不显眼,而大部分时间都在移动的蜥蜴很容易被看到。

坐等蜥蜴可能最有可能被活跃的捕食者发现和捕获,而广泛觅食的蜥蜴很可能被坐等捕食者捕获。

由于这种差异,觅食模式可能在食物链中的连续水平上交替:四处走动的昆虫可能会被坐等觅食的蜥蜴捕获,而这些蜥蜴可能会被活跃的捕食者吃掉,而久坐不动的昆虫可能会吃掉它们。

更有可能被活跃的觅食蜥蜴发现,3.在第2段中,为什么作者将大部分时间静止不动的蜥蜴的可见性与大部分时间移动的蜥蜴的可见性进行对比?O 表明蜥蜴有可能在食物链的连续水平上交替觅食模式O 建议坐等蜥蜴比活跃的蜥蜴更容易受到捕食者的攻击O 解释为什么坐等蜥蜴在捕食昆虫方面比活跃的蜥蜴更成功O 解释蜥蜴的觅食策略如何影响可能攻击它的捕食者类型第3 段:静坐觅食者的身体形态可能反映了与活跃觅食者不同的选择压力。

1A recent study has provided clues to predator-prey dynamics in the late Pleistocene era.Researchers compared the number of tooth fractures in carnivores that lived 36,000to10,000years ago and that were preserved in the Rancho La Brea tar pits in Los Angeles.The breakage frequencies in the extinct species were strikingly higher than those in the present-day species.In considering possible explanations for this finding,the researchers dismissed demographic bias because older individuals were not overrepresented in the fossil samples.They rejected preservational bias because a total absence of breakage in two extinct species demonstrated that the fractures were not the result of abrasion within the pits.They ruled out local bias because breakage data obtained from other Pleistocene sites were similar to the La Brea data.The explanation they consider most plausible is behavioral differences between extinct and present-day carnivores—in particular,more contact between the teeth of predators and the bones of prey due to more thorough consumption of carcasses by the extinct species.Such thorough carcass consumption implies to the researchers either that prey availability was low,at least seasonally,or that there was intense competition over kills and a high rate of carcass theft due to relatively high predator densities.近期的一项研究为更新世后期食肉动物的捕食动态提供了线索。
