点击下载2015年雅思听力真题PDF版【小马内部专用】剑桥雅思10中的阅读难度延续了剑8剑9的常规难度，所以总体来说还好。
海外版的剑桥雅思10一共就两套题，我们今天就来看一下其中Test1的阅读。
首先，第一篇文章标题是Bovids。
这个文章标题单词不认识时也不用担心，因为正文中第一句话就对这个单词开始了解释：The family of mammals called bovids belongs to……根据这半句话即可知道Bovids是一种哺乳动物统称，准确的意思是指“牛科动物”。
文章前三段描述了Bovids的主要居住在South-east Asia(东南亚)，大部分都喜欢居住在wide open spaces(开阔的地方);还描述了大概的外貌和大小以及特征。
然后第四段开始介绍Bovids的五种sub-families(分支)。
文章后有三个题型，第一大题是3个选择，通过题中定位词回文定位，答案集中于前三段。
第二大题是名称特征配对，五个特征作为题目，和四个Bovids类型配对，有NB，答案从第四段开始一直到最后。
第三大题是简答题5题，NO MORE THAN THREE WORDS, 范围是全篇范围，但都是显性定位词，所以定位和确定答案都不难。
第二篇文章标题是Photovoltaics on the rooftop(房顶上的太阳能电池). 就从标题来看的话因为有专有词汇所以没法知道这篇文章在讲什么，这时候看副标题：A natural choice for powering the family home. 从副标题和第一段的前两句可以知道这篇文章讲的是利用大自然给家庭供电。

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 Yet if the satellite service’s digital maps become even slightly outdated, you can become lost.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.

参考文章：(以下文章仅是相似相关内容，并非考试文章，仅供参考)Aquaculture in NewA Aquaculture is the general term given to the cultivation of any fresh or salt water plant or animal. It takes place in New Zealand in coastal marine areas (mariculture) and in inland tanks or enclosures.B Aquaculture in New Zealand currently (2008) occupies 14,188 ha. Of that area, 7,713 ha is in established growing areas and is owned by the aquaculture industry, 4,010 ha is used to enhance the wild scallop fishery and belongs to the Challenger Scallop Enhancement Company,[6] and 2,465 ha is an exposed site six kilometres offshore from Napier where trials are being undertaken by a private company to test the site's economic viability.C In 2005 the aquaculture industry provided direct employment for about 2,500 full time equivalents, mostly in the processing sector. A similar amount of indirect employment resulted from flow-on effects. The aquaculture industry is important for some coastal areas around New Zealand where there is limited employment. This applies particularly to some Maori communities with traditional links to coastal settlements.D Marine aquaculture, mariculture, occurs in the sea, generally in sheltered bays along the coast. In New Zealand, about 70 percent of marine aquaculture occurs in the top of the South Island. In the North Island, the Firth of Thames is productive.E Marine farmers usually look for sheltered and unpolluted waters rich in nutrients. Often these areas are also desirable for other purposes. In the late 1990s, demand forcoastal aquaculture space upsurged, increasing fivefold.[18] Aquaculture consents developed haphazardly, with regional councils unsure about how marine farms might impact coastal environments. By 2001, some councils were inundated with marine farm applications, and were operating with inadequate guidelines for sustainably managing the coast.[19] As the Ministry for the Environment put it: “Attempts to minimise local or cumulative environmental effects resulted in bottlenecks, delays and high costs in processing applications for new marine farms, local moratoria, submitter fatigue and poor environmental outcomes. Marine farmers, local communities, and the government wanted change.”F In 2002, the government stopped issuing consents for more new marine farms while they reformed the legislation. The consents had operated under a system overseen by both the Ministry of Fisheries and the regional councils. The reforms aimed to streamline these applications for both freshwater and marine farms. Industry farmers objected to the moratorium, on the grounds that delaying expansion and diversification could not be in the interest of the industry. Maori groups considered they were especially affected since they were the main applicants for coastal farms.G This took three years, and in early 2005, Parliament passed the Aquaculture Reform Act 2004, which introduced the new legislation. The act amends five existing acts to cope with the new environmental demands, and creates two new acts, the Maori Commercial Aquaculture Claims Settlement Act 2004 and the Aquaculture Reform (Repeals and Transitional Provisions) Act 2004.[20] The legislation and administration of aquaculture inNew Zealand is complex for such a small industry. A more comprehensive overview can be found here.H Aquaculture is administered in New Zealand through labyrinth bureaucracies, with consequent diluted responsibilities. No single ministerial portfolio or government agency is responsible. As an example, in 2007 the government released a strategy on aquaculture. This strategy was endorsed by six government ministers with the following portfolios: fisheries, environment, conservation, local government, Maori affairs, industry and regional development. Further, there were five government departments directly involved in the preparation of the strategy. As another example, the access to marine and freshwater aquaculture sites are under the control of 17 regional local government agencies with yet more oversight by various central government agencies.参考答案：14. vi ( 一受益的村庄)15. 选含beginning的那项16. 选含limitation的那项17. 选含concerns to environment 的那项18. 选含alternative explanation 的那项19. 选含research的那项20. 选含science and business 的那项21.

雅思阅读考试模拟测试题带答案
雅思阅读考试模拟测试题带答案2015年雅思阅读考试模拟测试题带答案It is estimated that around of the approximately six thousand languages that are spoken today, over three thousand of them are likely to have disappeared by the year 2100. Many of these are now classified as endangered languages and are classified as such by factors such as the number of speakers a language has, the age of the speakers, and the percentage of the youngest generation acquiring fluency in the language. For example, a language with many tens of thousands of speakers may be considered endangered if the children in the community are no longer learning the language. This scenario may happen in a place like Indonesia which as many different languages in use, but is trying to make communication easier by teaching a national language nation-wide. In another scenario, a language may only have a few hundred speakers but may not be considered endangered because all of the children in the community are learning the language.Once a language is classified as endangered, conservation efforts may be made in an attempt to save or revive the language. Whether or not to make such efforts is a decision which is ultimately made by the speakers of the language themselves, but success often requires a great deal of help and approval from the government or other authorities.One of the most famous language conservation success stories is that of the Welsh language. Historically, large numbers of Welsh people spoke only Welsh, but eventually English became the main language of Wales and fewer and fewer people learned Welsh. Conservation efforts began to be made in themid-20th century with the establishment of such organisations as the Welsh Language Association in 1962. The Welsh Language Act and the Government of Wales Act, both passed in the 1990s, protected the Welsh language and made sure that English and Welsh would have equal status in Wales. Since 2000, the study of the Welsh language has been a compulsory subject in school. Today, over 22% of the population of Wales are Welsh speakers, up from 18% in 1991.Another famous example, Hebrew, is not so much a story of language conservation as much as language revitalisation. Hebrew was once a spoken language but by the 4th century BCE it had been replaced by Aramaic. Hebrew continued to be used for religious purposes and in literature but the language was no longer used for everyday purposes. In the 19th century, there was a movement to revive Hebrew as a spoken language, and when the State of Israel was founded in 1948, Hebrew was adopted as the official language. There was some resistance to this idea, as Hebrew was considered a religious language, not a language to be used for common communication. In addition, because Hebrew was an ancient language, it lacked many of the words that are used in modern times and many new words had to be coined. However, because there was a need for a common language in Israel, the language was accepted and now thrives.The successes of language conservation are many, but many more attempts at language preservation do not succeed and there are many languages that have not survived except for a few recordings made by the last native speakers before their deaths. In some cases, the number of remaining speakers at the start of conservation efforts was not enough to sustain revitalisation, and in others, efforts may fail because there is often no economicbenefit to learning an endangered language at the expense of a more commonly spoken national or international language.QuestionsDo the following statements agree with the information given in the article?In boxes 1-10 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 this1) Half of the languages spoken today will be gone by 2100.2) A language may be considered endangered if children of the speakers are no longer learning the language.3) Indonesian is an endangered language.4) Most endangered languages today are saved and revived.5) Welsh was revived mainly due to government legislature.6) The number of Welsh speakers is expected to rise rapidly in the future.7) All school lessons in Wales are taught in Welsh.8) Hebrew died out completely in the 4th century BCE.9) Hebrew and Aramaic are similar languages.10) Many new terms had to be added to Hebrew to make it functional for today’s world.Answers1) F2) T3) NG4) F5) T6) NG7) NG8) F9) NG10) T【2015年雅思阅读考试模拟测试题带答案】。

二、具体题目分析A卷Passage 1 ：题目：小岛旅游参考文章(原文有删减)：Eco-Resort Management PracticesA Ecotourism is often regarded as a form of nature-based tourism and has become an important alternative source of tourists. In addition to providing the traditional resort-leisure product, it has been argued that ecotourism resort management should have a particular focus on best-practice environmental management, an educational and interpretive component, and direct and indirect contributions to the conservation of the natural and cultural environment (Ayala, 1996).B Couran Cove Island Resort is a large integrated ecotourism-based resort located south of Brisbane on the Gold Coast, Queensland, Australia. As the world's population becomes increasingly urbanised, the demand for tourist attractions which are environmentally friendly, serene and offer amenities of a unique nature, has grownrapidly. Couran Cove Resort, which is one such tourist attractions, is located on South Stradbroke Island, occupying approximately 150 hectares of the island. South Stradbroke Island is separated from the mainland by the Broadwater, a stretch of sea 3 kilometers wide More than a century ago, there was only one Stradbroke Island, and there were at least four nitribes living and hunting on the island. Regrettably, most of the original island dwellers were eventually killed by diseases such as tuberculosis, smallpox and influenza by the end of the 19th century. The second ship wreak on the island in 1894, and the subsequent destruction of the ship (the Cambus Wallace) because it contained dynamite, caused a large crater in the sandhills on Stradbroke Island. Eventually, the ocean broke through the weakened land form and Stradbroke became two islands. Couran Cove Island Resort is built on one of the world's few naturally-occurring sand lands, which is home to a wide range of plant communities and one of the largest remaining remnants of the rare livistona (i) rainforest left on the Gold Coast. Many mangrove and rainforest areas, and Malaleuca Wetlands on South Stradbroke Island (and in Queensland), have been cleared, drained or filled for residential, industrial, agricultural or urban development in the first half of the 20th century. Farmers and graziers finally abandoned South Stradbroke Island in 1939 because the vegetation and the soil conditions there were not suitable for agricultural activities.SUSTAINABLE PRACTICES OF COUTRAN COVE RESORTBeing located on an offshore island, the resort is only accessible by means of water transportation. The resort provides hourly ferry service from the marina on the mainlandto and from the island. Within the resort, transport modes include walking trails, bicycle tracks and the beach train. The reception area is the counter of the shop which has not changed in 8 years at least. The accommodation is an octagonal "Bure (草屋，房子)'These are large rooms that are clean but! The equipment is tired and in some cases just working. Our ceiling fan only worked on high speed for example. Beds are hard but clean, there is television, radio, an old air conditioner and a small fridge. These "Bures" are right on top of each other and night noises do carry so be careful what you say and do. The only thing is the mosquitoes but if you forget to bring mosquito repellant they sell some on the island.As an ecotourism-based resort, most of the planning and development of the attraction has been concentrated on the need to co-exist with the fragile natural environment of South Stradbroke Island to achieve sustainable development.WATER AND ENERGY MANAGEMENTC South Stradbroke Island has groundwater at the centre of the island, which has a maximum height of 3 metres above sea level. The water supply is recharged by rainfall and is commonly known as an unconfined freshwater aquifer C 蓄水层)•Couran Cove Island Resort obtains its water supply by tapping into this aquifer and extracting it via a bore system. Some of the problems which have threatened the island's freshwater supply include pollution, contamination and over-consumption. In order to minimise some of these problems, all laundry activities are carried out on the mainland. The resort considers washing machines as onerous to the island's freshwater supply, and that the detergentscontain a high level of phosphates which are a major source of water pollution. The resort uses LPG-power generation rather than a diesel-powered(柴油动力) plant for its energy supply, supplemented by wind turbine, which has reduced greenhouse emissions by 70% of diesel-equivalent generation methods. Excess heat recovered from the generator is used to heat the swimming pool. Hot water in the eco-cabins and for some of the resort's vehicles are solar-powered. Water efficient fittings are also installed in showers and toilets. However, not all the appliances used by the resort are energy efficient, such as refrigerators. Visitors who stay at the resort are encouraged to monitor their water and energy usage via the in-house television systems, and are rewarded with prizes (such as a free return trip to the resort) accordingly if their usage level is low.CONCLUDING REMARKSD We examined a case study of good management practice and a pro-active sustainable tourism stance of an eco-resort. In three years of operation, Couran Cove Island Resort has won 23 international and national awards, including the 2001 Australian Tourism Award in the 4-Star Accommodation category. The resort has embraced and has effectively implemented contemporary environmental management practices. It has been argued that the successful implementation of the principles of sustainability should promote long-term social, economic and environmental benefits, while ensuring and enhancing the prospects of continued viability for the tourism enterprise. Couran Cove Island Resort does not conform to the characteristics of the Resort Development Spectrum, as proposed by Prideaux (2000). According to Prideaux, the resort should be atleast at Phase 3 of the model (the National tourism phase), which describes an integrated resort providing 3-4 star hotel-type accommodation. The primary tourist market in Phase 3 of the model consists mainly of interstate visitors. However, the number of interstate and international tourists visiting the resort is small, with the principal visitor markets comprising locals and residents from nearby towns and the Gold Coast region. The carrying capacity of Couran Cove does not seem to be of any concern to the Resort management. Given that it is a private commercial ecotourist enterprise, regulating the number of visitors to the resort to minimize damage done to the natural environment on South Stradbroke Island is not a binding constraint. However, the Resort7s growth will eventually be constrained by its carrying capacity, and quantity control should be incorporated in the management strategy of the resort.Passage 2 ：内容：机器人与小孩参考答案：待补充Passage 3 ：内容：海豚参考答案：待补充B卷Passage 1 ：题目：Energy from the Ocean内容：海洋中可以利用的4种能源，分别为tidal power, marine current power, wave power, ocean thermal energy a题型：多选3+匹配5+填空题5道参考答案：多选题(7选3 )在海洋中建立Tidal power plant 的positive effects ?A range of sea shoreB cost of establishing a tidal power plantC it is helpful to establish transportation systemD effect of fish and some other sea life around配对题A Tidal energyB Current energyC Thermal energy题目集合均关于三种能量在现阶段开采、使用的程度以及未来发展的潜力(NB )1. which kind of energy has already been subject to a successful trial AA2.

The expansion of desert like conditions into areas where they did not previously exist is called desertification. It has been estimated that an additional one-fourth of the Earth's land surface is threatened by this process.Desertification is accomplished primarily through the loss of stabilizing natural vegetation and the subsequent accelerated erosion of the soil by wind and water. In some cases the loose soil is blown completely away, leaving a stony surface. In other cases, thefiner particles may be removed, while the sand-sized particles are accumulated to form mobile hills or ridges of sand.Even in the areas that retain a soil cover, the reduction of vegetation typically results in the loss of the soil's ability to absorb substantial quantities of water. The impact of raindrops on the loose soil tends to transfer fine clay particles into the tiniest soil spaces, sealing them and producing a surface that allows very little water penetration. Water absorption is greatly reduced; consequently runoff is increased, resulting in accelerated erosion rates. The gradual drying of the soil caused by its diminished ability to absorb water results in the further loss of vegetation, so that a cycle of progressive surface deterioration is established.In some regions，the increase in desert areas is occurring largely as the result of a trend toward drier climatic conditions. Continued gradual global warming has produced an increase in aridity for some areas over the past few thousand years. The process may be accelerated in subsequent decades if global warming resulting from air pollution seriously increases.There is little doubt, however, that desertification in most areas results primarily from human activities rather than natural processes. The semiarid lands bordering the deserts exist in a delicate ecological balance and are limited in their potential to adjust to increased environmental pressures. Expanding populations are subjecting the land to increasing pressures to provide them with food and fuel. In wet periods, the land may be able to respond to these stresses. During the dry periods that are common phenomenaalong the desert margins, though, the pressure on the land is often far in excess of its diminished capacity, and desertification results.Four specific activities have been identified as major contributors to the desertification processes: over cultivation, overgrazing, firewood gathering, and over irrigation. The cultivation of crops has expanded into progressively drier regions as population densities have grown. These regions are especially likely to have periods of severe dryness, so that crop failures are common. Since the raising of most crops necessitates the prior removal of the natural vegetation, crop failures leave extensive tracts of land devoid of a plant cover and susceptible to wind and water erosion.The raising of livestock is a major economic activity in semiarid lands, where grasses are generally the dominant type of natural vegetation. The consequences of an excessive number of livestock grazing in an area are the reduction of the vegetation cover and the trampling and pulverization of the soil. This is usually followed by the drying of the soil and accelerated erosion.Firewood is the chief fuel used for cooking and heating in many countries. The increased pressures of expanding populations have led to the removal of woody plants so that many cities and towns are surrounded by large areas completely lacking in trees and shrubs. The increasing use of dried animal waste as a substitute fuel has also hurt the soil because this valuable soil conditioner and source of plant nutrients is no longer being returned to the land.The final major human cause of desertification is soil salinization resulting from overirrigation. Excess water from irrigation sinks down into the water table. If no drainage system exists, the water table rises, bringing dissolved salts to the surface. The water evaporates and the salts are left behind, creating a white crustal layer that prevents air and water from reaching the underlying soil.The extreme seriousness of desertification results from the vast areas of land and the tremendous numbers of people affected, as well as from the great difficulty of reversing or even slowing the process. Once the soil has been removed by erosion, only the passage of centuries or millennia will enable new soil to form. In areas where considerable soil still remains, though, a rigorously enforced program of land protection and cover-crop planting may make it possible to reverse the present deterioration of the surface.参考答案：段落信息配对题1.

延伸阅读：雅思阅读评分标准(一)介绍类学术说明文的结构要判断文章类别，一般看标题就可以了。
介绍类文章是对某事物或现象进行描述或介绍，所以标题一般为名词短语或者以How开头的疑问句。
具体结构如下：Introduce a phenomenon or a fact.Detailed Description:Timeline/Different Aspects/Logic DevelopmentLook into the future/Summary无论什么文章，起始段总是引出主题，所以多用叙述描写性语言，或介绍现象，或陈述事实，或交代问题。
在介绍类说明文中，中间断落是对事物细节的展开描述，各种话题可以通过三种不同方式展开。
第一类时间顺序，通常用于陈述一个历史事件，例如剑五中的“Johnson’s Dictionary”就是这一类。
第二类并列或递进，从各个侧面来介绍，例如剑四中的“What Do Whales feel?”，一看标题就知道是介绍鲸鱼各个感官的，属于并列结构。
第三类是逻辑顺序，据笔者统计，环境自然类文章多依照这种顺序，下文对此会作详细评述，这里不再赘言。
(二)论证类文章的结构(1)实验类文章Introduce ExperimentPreexperiment (Subjects, Tools, Methods)Experiment ProcessResult (Collecting Data)Analyses and Syntheses在雅思阅读中，实验类文章结构最为固定。

2015雅思模拟试题及答案：阅读
2015雅思模拟试题及答案：阅读1. British scientists are preparing to launch trials of a radical new way to fight cancer, which kills tumours by infecting them with viruses like the common cold. 2. If successful, virus therapy could eventually form a third pillar alongside radiotherapy and chemotherapy in the standard arsenal against cancer, while avoiding some of the debilitating side-effects. 3. Leonard Seymour, a professor of gene therapy at Oxford University, who has been working on the virus therapy with colleagues in London and the US, will lead the trials later this year. Cancer Research UK said yesterday that it was excited by the potential of Prof Seymour's pioneering techniques. 4. One of the country's leading geneticists, Prof Seymour has been working with viruses that kill cancer cells directly, while avoiding harm to healthy tissue. "In principle, you've got something which could be many times more effective than regular chemotherapy," he said. 5. Cancer-killing viruses exploit the fact that cancer cells suppress the body's local immune system. "If a cancer doesn't do that, the immune system wipes it out. If you can get a virus into a tumour, viruses find them a very good place to be because there's no immune system to stop them replicating. You can regard it as the cancer's Achilles' heel." 6. Only a small amount of the virus needs to get to the cancer. "They replicate, you get a million copies in each cell and the cell bursts and they infect the tumour cells adjacent and repeat the process," said Prof Seymour. 7. Preliminary research on mice shows that the viruses work well on tumours resistant to standard cancer drugs. "It's an interesting possibility that they may have an advantage in killing drug-resistant tumours, which could be quite different to anything we've had before." 8. Researchers have known for some time that viruses can kill tumour cells and some aspects of the work have already been published in scientific journals. American scientists have previously injected viruses directly into tumours but this technique will not work if the cancer is inaccessible or has spread throughout the body. 9. Prof Seymour's innovative solution is to mask the virus from the body's immune system, effectively allowing the viruses to do what chemotherapy drugs do - spread through the blood and reach tumours wherever they are. The big hurdle has always been to find a way to deliver viruses to tumours via the bloodstream without the body's immune system destroying them on the way. 10. "What we've done is make chemical modifications to the virus to put a polymer coat around it - it's a stealth virus when you inject it," he said. 11. After the stealth virus infects the tumour, it replicates, but the copies do not have the chemical modifications. If they escape from the tumour, the copies will be quickly recognised and mopped up by the body's immune system. 12. The therapy would be especially useful for secondary cancers, called metastases, which sometimes spread around the body after the first tumour appears. "There's an awful statistic of patients in the west ... with malignant cancers; 75% of them go on to die from metastases," said Prof Seymour. 13. Two viruses are likely to be examined in the first clinical trials: adenovirus, which normally causes a cold-like illness, and vaccinia, which causes cowpox and is also used in the vaccine against smallpox. For safety reasons, both will be disabled to make them less pathogenic in the trial, but Prof Seymour said he eventually hopes to use natural viruses. 14. The first trials will use uncoated adenovirus and vaccinia and will be delivered locally to liver tumours, in order to establish whether the treatment is safe in humans and what dose of virus will be needed. Several more years of trials will be needed, eventually also on the polymer-coated viruses, before the therapy can be considered for use in the NHS. Though the approach will be examined at first for cancers that do not respond to conventional treatments, Prof Seymour hopes that one day it might be applied to all cancers. Questions 1-6 Do the following statements agree with the information given in the reading passage? For questions 1-6 write TRUE if the statement agrees with the information FALSE if the statement contradicts the information NOT GIVEN if there is no information on this in the passage 1.Virus therapy, if successful, has an advantage in eliminating side-effects. 2.Cancer Research UK is quite hopeful about Professor Seymour’s work on the virus therapy. 3.Virus can kill cancer cells and stop them from growing again. 4.Cancer’s Achilles’ heel refers to the fact that virus may stay safely in a tumor and replicate. 5.To infect the cancer cells, a good deal of viruses should be injected into the tumor. 6.Researches on animals indicate that virus could be used as a new way to treat drug-resistant tumors. Question 7-9 Based on the reading passage, choose the appropriate letter from A-D for each answer. rmation about researches on viruses killing tumor cells can be found (A) on TV (B) in magazines (C) on internet (D) in newspapers 8.To treat tumors spreading out in body, researchers try to (A) change the body’ immune system (B) inject chemotherapy drugs into bloodstream. (C) increase the amount of injection (D) disguise the viruses on the way to tumors. 9.When the chemical modified virus in tumor replicates, the copies (A) will soon escape from the tumor and spread out. (B) will be wiped out by the body’s immune system. (C) will be immediately recognized by the researchers. (D) will eventually stop the tumor from spreading out.

A There are still debates about the originsof Polynesian culture, but one thing we can ensure is that Polynesia is not asingle tribe but a complex one. Polynesians which includes Marquesans，Samoans, Niueans, Tongans, Cook Islanders, Hawaiians, Tahitians, andMaori, arc genetically linked to indigenous peoples of parts of Southeast Asia.It s a sub-region of Occania, comprising of a large grouping of over 1 ,000islands scattered over the central and southern Pacific Ocean, within atriangle that has New Zealand, Hawaii and Easter Island as its corners.B Polynesian history has fascinated thewestern world since Pacific cultures were first contacted by European explorersin the late 18th century. The small island of Tikopia, for many people - evenfor many Solomon Islanders-- is so far away that it seems like a mythical land;a place like Namia that magi cal land in C. S. Lewis, classic, ‘The Chronicles of Namia.” Maybe because of it — Tikopia, its people, and their cultures have long fascinatedscholars, travelers, and casual observers. Like the pioneers Peter Dillion,Dumoni D' Urville and John Colleridge Patterson who visited and wrote about theisland in the 1800s, Raymond Firth is one of those people captured by thealluring attraction of Tikopia. As a result, he had made a number of trips tothe island since 1920s and recorded his experiences, observations and reflectionson Tikopia, its people, cultures and the changes that have occurred.C While engaged in study of the kinship andreligious life of the people of Tikopia, Firth made a few observations on theirtattooing. Brief though these notes are they may be worth putting on record asan indication of the sociological setting of the practice in this primitivePolynesian community. The origin of the English word ‘tattoo' actually comesfrom the Tikopia word 'tatau1. The word for tattoo marks in general is tau,and the operation of tattooing is known as ta tau, ta being thegeneric term for the act of striking.D The technique oftattooing was similar throughout Polynesia. Traditional tattoo artists createtheir indelible tattoos using pigment made from the candlenut or kukui nut.First, they bum the nut inside a bowl made of half a coconut shell. They thenscrape out the soot and use a pestle to mix it with liquid. Bluing is sometimesadded to counteract the reddish hue of the carbon-basedpigment. It also makesthe outline of the inscribed designs bolder on the dark skin of tattooingsubjects.E For the instrumentsused when tattooing, specialists used a range of chisels made from albatrosswing bone which were hafted onto a handle which was made from the heart wood ofthe bush and struck with a mallet. The tattooer began by sketching withcharcoal a design on the supine subject, whose skin at that location wasstretched taut by one more apprentices. The tattooer then dipped the appropriatepoints - either a single one or a whole comb into the ink (usually contained ina coconut-shell cup) and tapped it into the subject's skin, holding the bladehandle in one hand and tapping it with the other. The blood that usuallytrickled from the punctures was wiped away either by the tattooer or hisapprentice, the latter having also served by restraining a pain-wracked subjectfrom moving, for the operation was inevitably painful a test of fortitude thattattooers sought to shorten by working as fast as possible. In fact, tattoosnearly always festered and often led to sickness - and in some cases death.F In ancient Polynesian society, nearlyeveryone was tattooed. It was an integral part of ancient culture and was muchmore than a body ornament. Tattooing indicated ones genealogyand/or rank insociety. It was a sign of wealth, of strength and of the ability to endurepain. Those who went without them were seen as persons of lower social status.As such, chiefs and warriors generally had the most elaborate tattoos.Tattooing was generally begun at adolescence，and would often not be completed for a number of years. Receivingtattoo constituted an important milestone between childhood and adulthood, andwas accompanied by many rites and rituals. Apart from signaling status andrank, another reason for the practice in traditional times was to make a personmore attractive to the opposite sex.G The male facial tattoo is generallydivided into eight sections of the face. The center of the forehead designateda person's general rank. The area around the brows designated his position. Thearea around the eyes and the nose designated his hapu, or sub-tribe rank. Thearea around the temples served to detail ms marital status, like the number ofmarriages. The area under the nose displayed his signature. This signature wasonce memorized by tribal chiefs who used it when buying property, signingdeeds, and officiating orders. The cheek area designated the nature of theperson's work. The chin area showed the person's mana. Lastly, the jaw areadesignated a person's birth status.H A person's ancestry is indicated on eachside of the face. The left side is generally the father's side，and the right side was the mother's. The manutahi design is workedon the men’s back. It consists of two vertical lines drawn down the spine, withshort vertical lines between them. When a man had the manutahi on his back, he took pride in himself. At gatherings of the peoplehe could stand forth in their midst and display histattoo designs with songs. And rows of triangles design on the men's chestindicate his bravery.I Tattoo was a way delivering informationof its owner. It’s also a traditional method to fetch spiritual power,protection and strength. The Polynesians use this as a sign of character,position and levels in a hierarchy. Polyne sian peoples believe that a person’smana, their spiritual power or life force, is displayed through their tattoo.部分答案：判断题1.

Passage 1 ： 题⽬：Seed Hunting 内容：濒危种⼦ 题型：填空概括题4+判断题6+多选题2 题号：旧题 ⽂章参考： Seed Hunting With quarter of the world's plants set to vanish within the next 50 years, Alexander reports on the scientists working against the clock the preserve the Earth's botanical heritage. They travel the four comers of the globe, scouringjungles，forests and savannas. But they‘re not looking for ancient artefacts，lost treasure or undiscovered tombs. Just pods. It may lack the romantic allure of archaeology, or the whiff of danger that accompanies going after big game, but seed hunting is an increasingly serious business. Some seek seeds for profit hunters in the employ of biotechnologyfirms，pharmaceutical companies and private corporations on the lookout for species that will yield the drugs or crops of the future. Others collect to conserve, working to halt the sad slide into extinction facing so many plant species. Among the pioneers of this botanical treasure hunt was John Trade scant, an English royal gardener who brought back plants and seeds from his journeys abroad in the early 1600s. Later， the English botanist Sir Joseph Banks-who was the first director of the Royal Botanic Gardens at Kew and travelled with Captain James Cook on his voyages near the end of the 18th century—was so driven to expand his collections that he sent botanists around the world at his own expense. Those heady days of exploration and discovery may be over, but they have been replaced by a pressing need to preserve our natural history for the future. This modem mission drives hunters such as Dr Michiel van Slageren，a good-natured Dutchman who often sports a wide-brimmed hat in the field⼀he could easily be mistaken for the cinematic hero Indiana Jones. He and three other seed hunters work at the Millennium Seed Bank，an 80 million [pounds sterling] international conservation project that aims to protect the world's most endangered wild plant species. The group's headquarters are in a modem glass-and-concrete structure on a 200-hectare Estate at Wakehurst Place in the West Sussex countryside. Within its underground vaults are 260 million dried seeds from 122 countries, all stored at -20 Celsius to survive for centuries. Among the 5，100 species represented are virtually all of Britain's 1,400 native seed-bearing plants, the most complete such collection of any country‘s flora. Overseen by the Royal botanic gardens, the Millennium Seed Bank is the world's largest wild-plant depository. It aims to collect 24,000 species by 2010. The reason is simple: thanks to humanity’s efforts，an estimated 25 percent of the world's plants are on the verge of extinction and may vanish within 50 years. We're currently responsible for habitat destruction on an unprecedented scale，and during the past 400 years，plant species extinction rates have been about 70 times greater than those indicated by the geological record as being ‘normal’. Experts predict that during the next 50 years a further one billion hectares of wilderness will be converted to farmland in developing countries alone. The implications of this loss are enormous. Besides providing staple food crops，plants are a source of many machines and the principal supply of fuel and building materials in many parts of the world. They also protect soil and help regulate the climate. Yet，across the globe，plant species are being driven to extinction before their potential benefits are discovered. The world Conservation Union has listed 5,714 threatened species is sure to be much higher. In the UK alone, 300 wild plant species are classified as endangered. The Millennium Seed Bank aims to ensure that even if a plant becomes extinct in the wild，it won‘t be lost forever. Stored seeds can be used the help restore damaged or destroyed environment or in scientific research to find new benefits for society- in medicine, agriculture or local industry- that would otherwise be Seed banks are an insurance policy to protect the world’s plant heritage for the future, explains Dr Paul Smith，another Kew seed hunter. "Seed conservation techniques were originally developed by farmers，" he says. "Storage is the basis what we do，conserving seeds until you can use them-just as in farming." Smith says there's no reason why any plant species should become extinct，given today’s technology. But he admits that the biggest challenge is finding，naming and categorising all the world's plants. And someone has to gather these seeds before it’s too late. "There aren't a lot of people out there doing this，" he says." The key is to know the flora from a particular area, and that knowledge takes years to acquire." There are about 1,470 seed banks scattered around the globe，with a combined total of 5.4 million samples，of which perhaps two million are distinct non-duplicates. Most preserve genetic material for agriculture use in order to ensure cropdiversity; others aim to conserve wild species，although only 15 per cent of all banked plants are wild. Many seed banks are themselves under threat due to a lack of funds. Last year, Imperial College, London，examined crop collections from 151 countries and found that while the number of plant samples had increased in two thirds of the countries，budget had been cut in a quarter and remained static in another 35 per cent. The UN's Food and Agriculture Organization and the Consultative Group on International Agricultural Research has since set up the Global Conservation Trust，which aims to raise US $260 million to protect seed banks in perpetuity. 题⽬参考： Question 14-19 TRUE/FALSE/ NOT GIVEN 14. The purpose of collecting seeds now is different from the past. True 15. The millennium seed bank is the earliest seed bank. Not given 16. One of major threats for plant species extinction is farmland expansion into wildness. True 17. The approach that scientists apply to store seeds is similar to that used by farmers. True 18. Technological development is the only hope to save plant species. False 19. The works of seed conservation are often limited by financial problems. True Question 20-24 Summary Some people collect seeds for the purpose of protecting certain species from 20 extinction; others collect seeds for their ability to produce 21 drugs，crops. They are called seed hunters. The 22 pioneers of them included both gardeners and botanists, such as 23 Sir Joseph Banks，who financially supported collectors out of his own pocket. The seeds collected are usually stored in seed banks，one of which is the famous millennium seed bank，where seeds are all stored in the 24 underground vaults at a low temperature. Question 25-26 Multiple choice Which TWO of the following are provided by plants to the human? AB A food B fuels C clothes D energy E commercial products (顺序可能有误，仅供参考) Passage 2 : 题⽬：Implication of False Belief Experiments 内容：错误信念实验 题型：段落信息配对题7+概括题7 参考⽂章：(⽂章为部分回忆贫选，仅供参考) Implication of False Belief Experiments A A considerable amount of research since the mid 1980s has been concerned with what has been termed children’s theory of mind. This involves children’s ability to understand that people can have different beliefs and representations of the world -a capacity that is shown by four years of age. Furthermore, this ability appears to be absent in children with autism. The ability to work out what another person is thinking is clearly an important aspect of both cognitive and social development. Furthermore, one important explanation for autism is that children suffering from this condition do not have a theory of mind (TOM). Consequently, the development of children’s TOM has attracted considerable attention. B Wimmer and Pemer devised a 'false belief task5 to address this question. They used some toys to act out the followingstory. Maxi left some chocolate in a blue cupboard before he went out. When he was away his mother moved the chocolate to a green cupboard. Children were asked to predict where Maxi will look for his chocolate when he returns. Most children under four years gave the incorrect answer，that Maxi will look in the green cupboard. Those over four years tended to give the correct answer, that Maxi will look in the blue cupboard. The incorrect answers indicated that the younger children did not understand that Maxi’s beliefs and representations no longer matched the actual state of the world, and they failed to appreciate that Maxi will act on the basis of his beliefs rather than the way that the world is actually organised. C A simpler version of the Maxi task was devised by Baron-Cohen to take account of criticisms that younger children may have been affected by the complexity and too much information of the story in the task described above. For example, the child is shown two dolls， Sally and Anne, who have a basket and a box，respectively. Sally also has a marble，which she places in her basket，and then leaves to take a walk. While she is out of the room，Anne takes the marble from the basket, eventually putting it in the box. Sally returns, and the child is then asked where Sally will look for the marble. The child passes the task if she answers that Sally will look in the basket，where she put the marble; the child fails the task if she answers that Sally will look in the box，where the child knows the marble is hidden，even though Sally cannot know, since she did not see it hidden there. In order to pass the task，the child must be able to understand that another’s mental representation of the situation is different from their own，and the child must be able to predict behavior based on that understanding. The results of research using false-belief tasks have been fairly consistent: most normally-developing children are unable to pass the tasks until around age four. D Leslie argues that，before 18 months，children treat the world in a literal way and rarely demonstrate pretence. He also argues that it is necessary for the cognitive system to distinguish between what is pretend and what is real. If children were not able to do this, they would not be able to distinguish between imagination and reality. Leslie suggested that this pretend play becomes possible because of the presence of a de-coupler that copies primary representations to secondary representations. For example, children，when pretending a banana is a telephone, would make a secondary representation of a banana. They would manipulate this representation and they would use their stored knowledge of 'telephone5 to build on this pretence. E There is also evidence that social processes play a part in the development of TOM. Meins and her colleagues have found that what they term mindmindedness in maternal speech to six-month old infants is related to both security of attachment and to TOM abilities. Mindmindedness involves speech that discusses infants5 feelings and explains their behaviour in terms of mental states (e. g. < you’re feeling hungry’).。
2015SAT阅读练习及答案解析
2015年SAT阅读真题Nearly a century ago, biologists found that if they separated an invertebrate animal embryo into two partsat an early stage of its life, it would survive and developas two normal embryos. This led them to believe that the (5) cells in the early embryo are undetermined in the sense that each cell has the potential to develop in a variety of different ways. Later biologists found that the situationwas not so simple. It matters in which plane the embryois cut. If it is cut in a plane different from the one used (10)by the early investigators, it will not form two whole embryos.A debate arose over what exactly was happening. Which embryo cells are determined, just when do they become irreversibly committed to their fates, and what (15)are the “morphogenetic determinants” that tell a cell what to become? But the debate could not be resolved because no one was able to ask the crucial questionsin a form in which they could be pursued productively. Recent discoveries in molecular biology, however, have (20) opened up prospects for a resolution of the debate. Now investigators think they know at least some of the molecules that act as morphogenetic determinants inearly development. They have been able o show that,in a sense, cell determination begins even before an egg (25) is fertilized.Studying sea urchins, biologist Paul Gross foundthat an unfertilized egg contains substances that functionas morphogenetic determinants. They are locatedin the cytoplasm of the egg cell; i.e., in that part of the (30) cell’s protoplasm that lies outside of the nucleus. In the unfertilized egg, the substances are inactive and are not distributed homogeneously. When the egg is fertilized,the substances become active and, presumably, governthe behavior of the genes they interact with. Since the (35) substances are unevenly distributed in the egg, when the fertilized egg divides, the resulting cells are differentfrom the start and so can be qualitatively different intheir own gene activity.The substances that Gross studied are maternal(40) messenger RNA’s --products of certain of the maternalgenes. He and other biologists studying a wide varietyof organisms have found that these particular RNA’sdirect, in large part, the synthesis of histones, a classof proteins that bind to DNA. Once synthesized, the(45) histones move into the cell nucleus, where section ofDNA wrap around them to form a structure that resemblesbeads, or knots, on a string. The beads are DNAsegments wrapped around the histones; the string is theintervening DNA. And it is the structure of these beaded(50)DNA strings that guides the fate of the cells in whichthey are located.1. The passage is most probably directed at which kind of audience?(A) State legislators deciding about funding levels for a state-funded biological laboratory(B) Scientists specializing in molecular genetics(C) Readers of an alumni newsletter published by the college that Paul Gross attended(D) Marine biologists studying the processes that give rise to new species(E) Undergraduate biology majors in a molecular biology course2. It can be inferred from the passage that the morphogenetic determinants present in the early embryo are(A) located in the nucleus of the embryo cells(B) evenly distributed unless the embryo is not developing normally(C) inactive until the embryo cells become irreversibly committed to their final function(D) identical to those that were already present in the unfertilized egg(E) present in larger quantities than is necessary for the development of a single individual3. The main topic of the passage is(A) the early development of embryos of lower marine organisms(B) the main contribution of modern embryology to molecular biology(C) the role of molecular biology in disproving older theories of embryonic development(D) cell determination as an issue in the study of embryonic development(E) scientific dogma as a factor in the recent debate over the value of molecular biology4. According to the passage, when biologists believed that the cells in the early embryo were undetermined, they made which of the following mistakes?(A) They did not attempt to replicate the original experiment of separating an embryo into two parts.(B) They did not realize that there was a connection between the issue of cell determination and the outcome of the separation experiment.(C) They assumed that the results of experiments on embryos did not depend on the particular animal species used for such experiments.(D) They assumed that it was crucial to perform the separation experiment at an early stage in the embryo’s life.(E) They assumed that different ways of separating an embryo into two parts would be equivalent as far as the fate of the two parts was concerned.5. It can be inferred from the passage that the initial production of histones after an egg is fertilized takes place(A) in the cytoplasm(B) in the maternal genes(C) throughout the protoplasm(D) in the beaded portions of the DNA strings(E) in certain sections of the cell nucleus6. It can be inferred from the passage that which of the following is dependent on the fertilization of an egg?(A) Copying of maternal genes to produce maternal messenger RNA’s(B) Sythesis of proteins called histones(C) Division of a cell into its nucleus and the cytoplasm(D) Determination of the egg cell’s potential for division(E) Generation of all of a cell’s morphogenetic determinants7. According to the passage, the morphogenetic determinants present in the unfertilized egg cell are which of the following?(A) Proteins bound to the nucleus(B) Histones(C) Maternal messenger RNA’s(D) Cytoplasm(E) Nonbeaded intervening DNA8. The passage suggests that which of the following plays a role in determining whether an embryo separated into two parts will two parts will develop as two normal embryos?Ⅰ.The stage in the embryo’s life at which the separation occursⅡ. The instrument with which the separations is accomplishedⅢ. The plane in which the cut is made that separates the embryo(A) Ⅰonly(B) Ⅱonly(C) Ⅰand Ⅱ.only(D) Ⅰand Ⅲ.only(E) Ⅰ,Ⅱ, and Ⅲ9. Which of the following circumstances is most comparable to the impasse biologists encountered in trying to resolve the debate about cell determination (lines 12-18)?(A) The problems faced by a literary scholar who wishes to use original source materials that are written in an unfamiliar foreign language(B) The situation of a mathematician who in preparing a proof of a theorem for publication detects a reasoning error in the proof(C) The difficulties of a space engineer who has to design equipment to function in an environment in which it cannot first be tested(D) The predicament of a linguist trying to develop a theory of language acquisition when knowledge of the structure of language itself is rudimentary at best(E) The dilemma confronting a foundation when the funds available to it are sufficient to support one of two equally deserving scientific projects but not both Correct Answers：EEDEABCDD。
2015年雅思阅读模拟试题及答案解析一
Sleep medication linked to bizarre behaviourNew evidence has linked a commonly prescribed sleep medication with bizarre behaviours， including a case in which a woman painted her front door in her sleep.UK and Australian health agencies have released information about 240 cases of odd occurrences， including sleepwalking， amnesia and hallucinations among people taking the drug zolpidem.While doctors say that zolpidem can offer much-needed relief for people with sleep disorders， they caution that these newly reported cases should prompt a closer look at its possible side effects.Zolpidem， sold under the brand names Ambien， Stilnoct and Stilnox， is widely prescribed to treat insomnia and other disorders such as sleep apnea. Various forms of the drug， made by French pharmaceutical giant Sanofi-Aventis， were prescribed 674，500 times in 2005 in the UK.A newly published report from Australia’s Federal Health Department describes 104 cases of hallucinations and 62 cases of amnesia experienced by people taking zolpidem since marketing of the drug began there in 2000. The health department report also mentioned 16 cases of strangesleepwalking by people taking the medication.Midnight snackIn one of these sleepwalking cases a patient woke with a paintbrush in her hand after painting the front door to her house. Another case involved a woman who gained 23 kilograms over seven months while taking zolpidem. “It was only when she was discovered in front of an open refrigerator while asleep that the problem was resolved，” according to the report.The UK’s Medicines and Healthcare products Regulatory Agency， meanwhile， has recorded 68 cases of adverse reactions to zolpidem from 2001 to 2005.The newly reported cases in the UK and Australia add to a growing list of bizarre sleepwalking episodes linked to the drug in other countries， including reports of people sleep-driving while on the medication. In one case， a transatlantic flight had to be diverted after a passenger caused havoc after taking zolpidem.Hypnotic effectsThere is no biological pathway that has been proven to connect zolpidem with these behaviours. The drug is a benzodiazepine-like hypnotic that promotes deep sleep by interacting with brain receptors for a chemical called gamma-aminobutyric acid. While parts of the brain become less active during deep sleep， the body can still move， making sleepwalking a possibility.The product information for prescribers advises that psychiatric adverse effects， including hallucinations， sleepwalking and nightmares， are more likely in the elderly， and treatment should be stopped if they occur.Patient advocacy groups say they would like government health agencies and drug companies to take a closer look at the possible risks associated with sleep medicines. They stress that strange sleepwalking and sleep-driving behaviours can have risky consequences.“When people do something in which they’re not in full control it’s always a danger，” says Vera Sharav of the New York-based Alliance for Human Research Protection， a US network that advocates responsible and ethical medical research practices.Tried and tested“The more reports that come out about the potential side effects of the drug，the more research needs to be done to understand if these are real side effects，”says sleep researcher Kenneth Wright at the University of Colorado in Boulder， US.Millions of people have taken the drug without experiencing any strange side effects， points out Richard Millman at Brown Medical School， director of the SleepDisorders Center of Lifespan Hospitals in Providence， Rhode Island， US. He says that unlike older types of sleep medications， zolpidem does not carry as great a risk of addiction.And Wright notes that some of the reports of “sleep-driving” linked to zolpidem can be easily explained： some patients have wrongly taken the drug right before leaving work in hopes that the medicine will kick in by the time they reach home. Doctors stress that the medication should be taken just before going to bed.The US Food & Drug Administration says it is continuing to "actively investigate" and collect information about cases linking zolpidem to unusual side effects.The Ambien label currently lists strange behaviour as a “special concern” for people taking the drug. “It’s a possible rare adverse event，” says Sanofi-Aventis spokesperson Melissa Feltmann， adding that the strange sleepwalking behaviours “may not necessarily be caused by the drug” but instead result from an underlying disorder. She says that “the safety profile [of zolpidem] is well established”. The drug received approval in the US in 1993.Questions 1-6 Do the following statements agree with the information given in the reading passage？In boxes 1-6 on your answer sheet writeTRUE if the statement is true according to the passageFALSE if the statement is false according to the passageNOT GIVEN if the information is not given in the passage1.

New studies have identified a bottleneck in our brains that some say means we are fundamentally incapable of true multitasking If experimental findings reflect real-world performance，people who think they are multitasking are probably just underperforming in all — or at best，all but one - of their parallel pursuits. Practice might improve your performance，but you will never be as good as when focusing on one task at a time.The problem，according to Rene Marois，a psychologist at Vanderbilt University in Nashville，Tennessee，is that there's a sticking point in the brain. To demonstrate this，Marois devised an experiment to locate it Volunteers watch a screen and when a particular image appears，a red circle，say，they have to press a key with their index finger. Different coloured circles require presses from different fingers. Typical response time is about half a second，and the volunteers quickly reach their peak performance. Then they learn to listen to different recordings and respond by making a specific sound. For instance，when they hear a bird chirp，they have to say "ba〃；an electronic sound should elicit a "ko"，and so on. Again，no problem. A normal person can do that in about half a second，with almost no effort.The trouble comes when Marois shows the volunteers an image，and then almost immediately plays them a sound Now they' re flummoxed."If you show an image and play a sound at the same time，one task is postponed，he says. In fact，if the second task is introduced within the half-second or so it takes to process and react to the first，it will simply be delayed until the first one is done. The largest dual-task delays occur when the two tasks are presented simultaneously；delays progressively shorten as the interval between presenting the tasks lengthens.There are at least three points where we seem to get stuck，says Marois. The first is in simply identifying what we‘re looking at This can take a few tenths of a second，during which time we are not able to see and recognize a second item. This limitation is known as the "attentional blink" ：experiments have shown that if you're watching out for a particular event and a second one shows up unexpectedly any time within this crucial window of concentration，it may register in your visual cortex but you will be unable to actupon it Interestingly，if you don7 t expect the first event，you have no trouble responding to the second. What exactly causes the attentional blink is still a matter for debate.A second limitation is in our short-term visual memory. It' s estimated that we can keep track of about four items at a time，fewer if they are complex. This capacity shortage is thought to explain，in part，our astonishing inability to detect even huge changes in scenes that are otherwise identical，so-called "change blindness" . Show people pairs of near-identical photos - say，aircraft engines in one picture have disappeared in the other - and they will fail to spot the differences. Here again，though，there is disagreement about what the essential limiting factor really is. Does it come down to a dearth of storage capacity，oris it about how much attention a viewer is paying？A third limitation is that choosing a response to a stimulus — braking when you see a child in the road，for instance，or replying when your mother tells you over the phone that she' s thinking of leaving your dad —also takes brainpower. Selecting a response to one of these things will delay by some tenths of a second your ability to respond to the other* This is called the "response selection bottleneck" theory，first proposed in 1952.But David Meyer，a psychologist at the University of Michigan，Ann Arbor，doesn't buy the bottleneck idea. He thinks dual-task interference is just evidence of a strategy used by the brain to prioritise multiple activities. Meyer is known as something of an optimist by his peers. He has written papers with titles like "Virtually perfect time-sharing in dual-task. people can benefit from practice. Not only did they learn to perform better，brain scans showed that underlying that improvement was a change in the way their brains become active. While if s clear that practice can often make a difference，especially as we age，the basic facts remain sobering. \ have this impression of an almighty complex brain/，says Marois，"and yet we have very humbling and crippling limits/' For most of our history，we probably never needed to do more than one thing at a time，he says，and so we haven't evolved to be able to. Perhaps we will in future，though. We might yet look back one day on people like Debbie and Alun as ancestors of a new breed of true multitaskers.参考答案：27. RM (A名)的实验目的是什么？D29. 28.
