剑桥雅思7TEST3阅读PASSAGE3参考译文：欧洲森林保护计划
雅思为各位考生推荐复习材料-剑桥雅思7TEST 3 PASSAGE 3 参考译文：欧洲森林保护计划,相应的解析，请点击：剑桥雅思7阅读+答案解析Test3Passage3。
TEST 3 PASSAGE 3 参考译文：欧洲森林保护计划森林是自然遗产的主要元素之一。
过去15年欧洲森林的退化程度已经逐渐让人们意识并了解到这种严重失调对他们的威胁。
欧洲国家越来越重视欧洲森林受到的主要威胁，除了地理和气候性的威胁以外，其他的都是不分国界的，诸如空气污染、土壤退化、与日俱增的森林火灾，有时候甚至是我们对林地和森林的管理不善。
人们也越来越清楚地认识到各国需要联合起来协调政策。
1990年12月，在法国斯特拉斯堡举行了第一次以保护欧洲森林为主题的部长级会议，来自东西欧的31国家代表汇集一堂。
会议的议题包括：如何协调研究对森林的破坏，如何防范森林火灾，以及欧洲森林生态系统研究项目的扩大。
会议举行前召开了两次专家会议来做会前准备工作。
他们最初的任务是决定在欧洲森林所面临的诸多问题中，哪个问题所涉及的国家最多，可作为各国联合行动的主题。
因此那些受特殊地理条件限制的地区，如地中海以及北欧国家就被排除在外了。
但是以后他们还是有可能参与进来的。
总体而言，欧洲国家认为森林有三重功能——生物、经济和娱乐功能。
第一重是扮演地球的“绿色之肺”;通过光合作用，森林在太阳能量转换过程中释放。
对人类而言，它是不可替代的巨大而无污染的能量来源。
同时，通过不断再生的木材，森林还为人类活动提供了原材料。
最后，森林还为那些在城市里每周五天深陷于工作的上班族们提供了无与伦比的自由氛围去释放心情，参与游猎、骑马以及远足等休闲活动。
森林的经济功能从人类起源开始就被发现了——木材就是最初的燃料。
其他功能的发现仅有几个世纪的历史，但它们变得越来越重要。
因此，整个欧洲十分关注威胁到森林使其不能扮演这三重基本功能的破坏性行为。
有关天然森林的古老神话还在欧洲大陆流传着，而事实上，真正的原始森林已经不复存在了。
剑桥雅思7阅读解析test
Q u e s t i o n 1 答案：YES关键词：1400 years定位原文: 第1段第2句：“Records show that only two have collapsed during the last 1400 years.”有记录显示，在过去1400年间，只有两座倒塌了。
解题思路: 使用1400 years定位到第一段第二句，该句明确表明1400年间只有两座日本宝塔倒塌Question 2答案：NO关键词：1995, Toji temple定位原文: 第1段最后1句：“Yet it led the magnificent five-storey pagoda ...”尽管大地震将京部附近东寺周围的大量建筑夷为平地，可寺里宏伟的五层宝塔却完好无损。
解题思路: 本题的考点在于要将原文中的leave...unscathed同题干中的destroy对立起来。
unscathed指“没有负伤的，未受损伤的”，这样就与题干中的destroy(毁坏)相抵触。
Question 3答案： NOT GIVEN关键词：30 years定位原文: 第2段第2句：“It was only thirty years ago that…”仅仅在 30 年前，建筑界的从业者们才有足够信心建造髙于十二层的钢筋混凝土办公大楼。
解题思路: 这句话与此题的唯一联系就是这个thirty years，抛开这一点，两者简直是牛头不对马嘴。
即使读完全段，也未见题干中所表达的意思，而且the other buildings near the Toji pagoda的勉强对等成分也出现在第一段a number of buildings in the neighbourhood。
一道题目的主要成分零散在文中数段，这就是典型的形散神必散型的NOT GIVEN。
Question 4答案： YES关键词: builders, weather定位原文: 第3段倒数第2句：“Clearly, Japanese carpenters of the day knew ...”显而易见，当时的日本木匠懂得一些窍门让建筑物可以顺风摇摆，不与自然力量对抗，而是顺应自然，从而稳稳矗立。
剑桥雅思真题7-阅读Test 3(附答案)
剑桥雅思真题7-阅读Test 3（附答案）Reading Passage 1You should spend about 20 minutes on QUESTIONS 1-13 which are based on Reading Passage 1 below.Ant IntelligenceWhen we think of intelligent members of the animal kingdom, the creatures that spring immediately to mind are apes and monkeys. But in fact the social lives of some members of the insect kingdom are sufficiently complex to suggest more than a hint of intelligence. Among these, the world of the ant has come in for considerable scrutiny lately, and the idea that ants demonstrate sparks of cognition has certainly not been rejected by those involved in these investigations.Ants store food, repel attackers and use chemical signals to contact one another in case of attack. Such chemical communication can be compared to the human use of visual and auditory channels (as in religious chants, advertising images and jingle s, political slogans and martial music) to arouse and propagate moods and attitudes. The biologist Lewis Thomas wrote, Ants are so much like human beings as to be an embarrassment. They farm fungi, raise aphids* as livestock, launch armies to war, use chemical sprays to alarm and confuse enemies, capture slaves, engage in child lab our, exchange information ceaselessly. They do everything but watch television.'However, in ants there is no cultural transmission -everything must be encoded in the genes -whereas in humans the opposite is true. Only basic instincts are carried in the genes of a newborn baby, other skills being learned from others in the community as the child grows up. It may seem that this cultural continuity gives us a huge advantage over ants. They have never mastered fire nor progressed. Their fungus farming and aphid herding crafts are sophisticated when compared to the agricultural skills of humans five thousand years ago but been totally overtaken by modern human agribusiness.Or have they? The farming methods of ants are at least sustainable. They do not ruin environments or use enormous amounts of energy. Moreover, recent evidence suggests that the crop farming of ants may be more sophisticated and adaptable than was thought.Ants were farmers fifty million years before humans were. Ants can't digest the cellulose in leaves - but some fungi can. They therefore cultivate these fungi in their nests, bringing them leaves to feed on, and then use them as a source of food. Farmer ants secrete antibiotics to control other fungi that might ac t as 'weeds', and spread waste to fertilize the crop.It was once thought that the fungus that ants cultivate was a single type that they had propagated, essentially unchanged from the distant past. Not so. Ulrich Mueller of Maryland and his colleagues genetically screened 8 62 different types of fungi taken from ants' nests. These turned out to be highly diverse: it seems that ants are continually domesticating new species. Even more impressively, DNA analysis of the fungi suggests that the ants improve or modify the fungi by regularly swapping and sharing strains with neighbouring ant colonies.Whereas prehistoric man had no exposure to urban lifestyles - the forcing house of intelligence -the evidence suggests that ants have lived in urban settings for close on a hundred million years, developing and maintaining underground cities of specialised chambers and tunnels.When we survey Mexico City, Tokyo, Los Angeles, we are amazed at what has been accomplishedby humans. Yet Hoelldobler and Wilson's magnificent work for ant lovers, The Ants, describes a supercolony of the ant Formica yessensis on the Ishikari Coast of Hokkaido. This 'megalopolis' was reported to be compose d of 360 million workers and a million queens living in 4, 500 interconnected nests a cross a territory of 2.7 square kilometres.Such enduring and intricately meshed levels of technical achievement outstrip by far anything achieved by our distant ancestors. We hail as masterpieces the cave paintings in southern France and elsewhere, dating back some 20,000 years. Ant societies existed in something like their present form more than seventy million years ago. Beside this, prehistoric ma n looks technologically primitive. Is this then some kind of intelligence, albeit of a different kind? Research conducted at Oxford, Sussex and Zurich Universities has shown that when desert ants return from a foraging trip, they navigate by integrating bearings and distances, which they continuously update in their heads. They combine the evidence of visual landmarks with a mental library of local directions, all within a framework which is consulted and updated. So ants can learn too.And in a twelve-year programmed of work, Ryabko and Reznikova have found evidence that ants can transmit very complex messages. Scouts who had located food in a maze returned to mobilise their foraging teams. They engaged in contact sessions, at the end of which the scout was removed in order to observe what her team might do. Often the foragers proceeded to the exact spot in the maze where the food had been. Elaborate precautions were taken to prevent the foraging team using odor clues. Discussion now centres on whether the route through the maze is communicated as a 'left-right' sequence of turns or as a 'compass bearing and distance ' message.During the course of this exhaustive study, Reznikova has grown so attached to her laboratory ants that she feels she knows them as individuals - even without the paint spots used to mark them. It's no surprise that Edward Wilson, in his essay, 'In the company of ants', advises readers who ask what to do with the ants in their kitchen to: 'Watch where you step. Be careful of little lives.' Question 1-6Do the following statements agree with the information given in Reading Passage 1?In boxes 1-6 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 this in the passage1. Ants use the same channels of communication as humans do.2. City life is one factor that encourages the development of intelligence.3. Ants can build large cities more quickly than humans do.4. Some ants can find their way by making calculations based on distance and position.5. In one experiment, foraging teams were able to use their sense of smell to find food.6. The essay, ‘In the company of ants’, explores ant communication.Question 7-13Complete the summary using the list of words, A-O, below.Write the correct letter, A-O, in boxes 7-13 on your answer sheet.Ants have sophisticated methods of farming, including herding livestock and growing crops, which are in many ways similar to those used in human agriculture. The ants cultivate a largenumber of different species of edible fungi which convert 7 …………into a form which they can digest. They use their own natural8………… as weed-killers and also use unwanted materials as 9………… Genetic analysis shows they constantly upgrade these fungi by developing new species and by 10 …………species with neighbouring ant colonies. In fact, the forming methods of ants could be said to be more advanced than human agribusiness, since they use 11 …………methods, they do not affect the 12………… and do not waste 13 ………… .You should spend about 20 minutes on QUESTIONS 14-26 which are based on Reading Passage 2 below.Population movements and geneticsA Study of the origins and distribution of human populations used to be based on archaeological and fossil evidence. A number of techniques developed since the 1950s, however, have placed the study of these subjects on a sounder and more objective footing. The best information on early population movements is now being obtained from the 'archaeology of the living body', the clues to be found in genetic material.B Recent work on the problem of when people first entered the Americas is an example of the value of these new techniques. North-east Asia and Siberia have long been accepted as the launching ground for the first human colonizers of the New World. But was there one major wave of migration across the Bering Strait into the Americas, or several? And when did this event, or events, take place？In recent years, new clues have come from research into genetics, including the distribution of genetic markers in modern Native Americans.C An important project, led by the biological anthropologist Robert Williams, focused on the variants (called Gm allotypes) of one particular protein -immunoglobin G-found in the fluid portion of human blood. All proteins 'drift', or produce variants, over the generations, and members of an interbreeding human population will share a set of such variants. Thus, by comparing the Gm allotypes of two different populations (e.g. two Indian tribes), one can establish their genetic 'distance', which itself can be calibrated to give an indication of the length of time since these populations last interbred.D Williams and his colleagues sampled the blood of over 5,000 American Indians in western North America during a twenty- year period. They found that their Gm allotypes could be divided into two groups, one of which also corresponded to the genetic typing of Central and South American Indians. Other tests showed that the Inuit (or Eskimo) and Aleut formed a third group. From this evidence it was deduced that there had been three major waves of migration across the Bering Strait. The first, Paleo-lndian, wave more than 15,000 years ago was ancestral to all Central and South American Indians. The second wave, about 14,000-12,000 years ago, brought Na-Dene hunters, ancestors of the Navajo and Apache (who only migrated south from Canada about 600 or 700 years ago). The third wave, perhaps 10,000 or 9,000 years ago, saw the migration from North-east Asia of groups ancestral to the modern Eskimo and Aleut.E How far does other research support these conclusions ？Geneticist Douglas Wallace has studied mitochondrial DNA in blood samples from three widely separated Native American groups: Pima- Papago Indians in Arizona, Maya Indians on the Y ucatan peninsula, Mexico, and Ticuna Indians in the Upper Amazon region of Brazil. As would have been predicted by Robert Williams's work, all three groups appear to be descended from the same ancestral (Paleo-lndian) population.F There are two other kinds of research that have thrown some light on the origins of the Native American population; they involve the study of teeth and of languages. The biological anthropologist Christy Turner is an expert in the analysis of changing physical characteristics in human teeth. He argues that tooth crowns and roots have a high genetic component, minimally affected by environmental and other factors. Studies carried out by Turner of many thousands of New and Old World specimens, both ancient and modern, suggest that the majority of prehistoric Americans are linked to Northern Asian populations by crown and root traits such as incisor shoveling (a scooping out on one or both surfaces of the tooth), single-rooted upper first premolars and triple-rooted lower first molars.According to Turner, this ties in with the idea of a single Paleo-lndian migration out of North Asia, which he sets at before 14,000 years ago by calibrating rates of dental micro-evolution. Tooth analyses also suggest that there were two later migrations of Na-Denes and Eskimo- Aleut.G The linguist Joseph Greenberg has, since the 1950s, argued that all Native American languages belong to a single 'Amerind' family, except for Na-Dene and Eskimo-Aleut - a view that gives credence to the idea of three main migrations. Greenberg is in a minority among fellow linguists, most of whom favour the notion of a great many waves of migration to account for the more than 1,000 languages spoken at one time by American Indians. But there is no doubt that the new genetic and dental evidence provides strong backing for Greenberg's view. Dates given for the migrations should nevertheless be treated with caution, except where supported by hard archaeological evidence.Question 14-19Reading Passage 2 has seven paragraphs, A-GChoose the correct heading for paragraphs A-F from the list of headings below.Write the correct number, i-x, into boxes 14-19 on your answer sheet.14Section A15Section A16Section A17Section A18Section A19Section AThe discussion of Williams's research indicates the periods at which early people are thought to have migrated along certain routes.

The decline of Europe's forests over the last decade and a half has led to an increasing awareness and understanding of the serious imbalances which threaten them.European countries are becoming increasingly concerned by major threats to European forests, threats which know no frontiers other than those of geography or climate: air pollution, soil deterioration, the increasing number of forest fires and sometimes even the mismanagement of our woodland and forest heritage. There has been a growing awareness of the need for countries to get together to co-ordinate their policies. In December 1990, Strasbourg hosted the first Ministerial Conference on the protection of Europe's forests. The conference brought together 31 countries from both Western and Eastern Europe. The topics discussed included the co-ordinated study of the destruction of forests, as well as how to combat forest fires and the extension of European research programs on the forest ecosystem. The preparatory work for the conference had been undertaken at two meetings of experts. Their initial task was to decide which of the many forest problems of concern to Europe involved the largest number of countries and might be the subject of joint action. Those confined to particular geographical areas, such as countries bordering the Mediterranean or the Nordic countriestherefore had to be discarded. However, this does not mean that in future they will be ignored.As a whole, European countries see forests as performing a triple function: biological, economic and recreational. The first is to act as a 'green lung' for our planet; by means of photosynthesis, forests produce oxygen through the transformation of solar energy, thus fulfilling what for humans is the essential role of an immense, non-polluting power plant. At the same time, forests provide raw materials for human activities through their constantly renewed production of wood. Finally, they offer those condemned to spend five days a week in an urban environment an unrivalled area of freedom to unwind and take part in a range of leisure activities, such as hunting, riding and hiking. The economic importance of forests has been understood since the dawn of man - wood was the first fuel. The other aspects have been recognised only for a few centuries but they are becoming more and more important. Hence, there is a real concern throughout Europe about the damage to the forest environment which threatens these three basic roles.The myth of the 'natural' forest has survived, yet there are effectively no remaining 'primary' forests in Europe. All European forests are artificial, having been adapted and exploited by man for thousands of years. This means that a forest policy is vital, that it must transcend national frontiers and generations of people, and that it must allow for the inevitable changes that take place in the forests, in needs, and hence in policy. The Strasbourg conference was one of the first events on such a scale to reach this conclusion. A general declaration was made that 'a central place in any ecologically coherent forest policy must be given to continuity over time and to the possible effects of unforeseen events, to ensure that the full potential of these forests is maintained'.That general declaration was accompanied by six detailed resolutions to assist national policy-making. The first proposes the extension and systematisation of surveillance sites to monitor forest decline. Forest decline is still poorly understood but leads to the loss of a high proportion of a tree's needles or leaves. The entire continent and the majority of species are now affected: between 30%and 50% of the tree population. The condition appears to result from the cumulative effect of a number of factors, with atmospheric pollutants the principal culprits. Compounds of nitrogen and sulphur dioxide should be particularly closely watched. However, their effects are probably accentuated by climatic factors, such as drought and hard winters, or soil imbalances such as soil acidification, which damages the roots. The second resolution concentrates on the need to preserve the genetic diversity of European forests. The aim is to reverse the decline in the number of tree species or at least to preserve the 'genetic material' of all of them. Although forest fires do not affect all of Europe to the same extent, the amount of damage caused the experts to propose as the third resolution that the Strasbourg conference consider the establishment of a European databank on the subject. All information used in the development of national preventative policies would become generally available. The subject of the fourth resolution discussed by the ministers was mountain forests. In Europe, it is undoubtedly the mountain ecosystem which has changed most rapidly and is most at risk. A thinly scattered permanent population and development of leisure activities, particularly skiing, have resulted in significant long-term changes to the local ecosystems. Proposed developments include a preferential research program on mountain forests. The fifth resolution relaunched the European research network on the physiology of trees, called Eurosilva. Eurosilva should support joint European research on tree diseases and their physiological and biochemical aspects. Each country concerned could increase the number of scholarships and other financial support for doctoraltheses and research projects in this area. Finally, the conference established the framework for a European research network on forest ecosystems. This would also involve harmonising activities in individual countries as well as identifying a number of priority research topics relating to the protection of forests. The Strasbourg conference's main concern was to provide for the future. This was the initial motivation, one now shared by all 31 participants representing 31 European countries. Their final text commits them to on-going discussion between government representatives with responsibility for forests.Question 27-33Do the following statements agree with the information given in Reading Passage 3?In boxes 27-33 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 this in the passage27.

Problems in Nordic countries were excluded because they are outside the European Economic Community.29. Forests are a renewable source of raw material.30. The biological functions of forests were recognised only in the twentieth century.31. Natural forests still exist in parts of Europe.32. Forest policy should be limited by national boundaries.33. The Strasbourg conference decided that a forest policy must allow for the possibility of change.Question 34-39Look at the following statements issued by the conference.Which six of the following statements, A-J, refer to the resolutions that were issued?Match the statements with the appropriate resolutions (Questions 34-39).Write the correct letter, A-J, in boxes 34-39 on your answer sheet.35Resolution 236Resolution 337Resolution 438Resolution 539Resolution 6Question 40Choose the correct letter, A, B, C or D.Write the correct letter in box 40 on your answer sheet.40.

Many elements may occur in seaweed—aluminium, barium, calcium, chlorine, copper, iodine and iron, to name but a few—traces normally produced by erosion and carried to the seaweed beds by river and sea currents. Seaweeds are also rich in vitamins: indeed, Eskimos obtain a high proportion of their bodily requirements of vitamin C from the seaweeds they eat.The nutritive value of seaweed has long been recognized. For instance, there is a remarkably low incidence of goiter amongst the Japanese, and for that matter, amongst our own Maori people, who have always eaten seaweeds, and this may well be attributed to the high iodine content of this food. Research into old Maori eating customs shows that jellies were made using seaweeds, fresh fruit and nuts, fuchsia and tutu berries, cape gooseberries, and many other fruits which either grew here naturally or were sown from seeds brought by settlers and explorers.Section BNew Zealand lays claim to approximately 700 species of seaweed, some of which have no representation outside this country. Of several species grown worldwide, New Zealand also has a particularly large share. For example, it is estimated that New Zealand has some 30 species of Gigartina, a close relative of carrageen or Irish moss. These are often referred to as the New Zealand carrageens. The gel-forming substance called agar which can be extracted from this species gives them great commercial application in seameal, from which seamealcustard is made, and in cough mixtures, confectionery, cosmetics, the canning, paint and leather industries, the manufacture of duplicating pads, and in toothpastes. In fact, during World War II, New Zealand Gigartina were sent to Australia to be used in toothpaste.Section CYet although New Zealand has so much of the commercially profitable red seaweeds, several of which are a source of agar(Pterocladia, Gelidium, Chondrus, Gigartina), before 1940 relatively little use was made of them. New Zealand used to import the Northern Hemisphere Irish moss(Chondrus crispus)from England and ready-made agar from Japan. Although distribution of the Gigartina is confined to certain areas according to species, it is only on the east coast of the North Island that its occurrence is rare. And even then, the east coast, and the area around Hokiangna, have a considerable supply of the two species of Pterocladia from which agar is also available. Happily, New Zealand-made agar is now obtainable in health food shops. Section D Seaweeds are divided into three classes determined by colour—red, brown and green—and each tends to live in a specific location. However, except for the unmistakable sea lettuce(Ulva), few are totally one colour; and especially when dry, some species can change colour quite significantly—a brown one may turn quite black, or a red one appear black, brown, pink or purple. Identification is nevertheless facilitated by the。

The topics discussed included the co - ordinated study of the destruction of forests , as well as how to combat forest fires and the extension of European research programs on the forest ecosystem . The preparatory work for the conference had been undertaken at two meetings of experts . Their initial task was to decide which of the many forest problems of concern to Europe involved the largest number of countries and might be the subject of joint action . Those confined to particular geographical areas , such as countries bordering the Mediterranean or the Nordic countries therefore had to be discarded . However , this does not mean that in future they will be ignored .。

剑桥雅思7TEST3阅读PASSAGE1参考译文：蚂蚁智能
雅思为各位考生推荐复习材料-剑桥雅思7TEST 3 PASSAGE 1 参考译文：蚂蚁智能,相应的解析，请点击：剑桥雅思7阅读答案+解析Test3Passage1。
TEST 3 PASSAGE 1 参考译文：蚂蚁智能每当我们想到动物界的智能成员时，头脑中立刻出现的会是猿和猴子。
事实上，在昆虫界，某些成员社会生活的复杂程度显示出了相当程度的智能。
其中蚂蚁世界就在最近成了主要的观察对象蚂蚁显示出一定认知力的观点也得到了研究人员的肯定。
蚂蚁储存食物，反击外敌，在攻击时用化学信号互相联系。
此类化学信号交流可与人类使用视觉和听觉途径(如圣歌、广告形象、铃声、政治标语以及军乐)来激发情绪和传递理念的行为相媲美。
生物学家 Lewis Thomas写道：“蚂蚁和人类是如此的相似，都让我们觉得自愧不如。
它们培育真菌，把蚜虫作为家畜来饲养，调配军队作战，用化学气雾发出替告和迷惑敌人，俘虏奴隶，忙于育婴，不停地交流信息。
除了不看电视它们什么都做。
”然而，蚂蚁的世界里没有文化的传播——所有的技能都必须存储在基因里——而人类的情况却恰恰相反。
人类新生儿的基因里只有基本的本能，其他技能则是在成长过程中从社会其他成员身上学习所得。
看起来这种文化传承使我们与蚂蚁相比具有巨大的优势。
它们从未掌握用火技术，也不知发展为何物，它们培育真菌、饲养蚜虫的技术和五千年前的人类农耕技术相比还算成熟，但却被人类现代的农业综合企业远远超越。
那么蚂蚁真的被人类超越了么?蚂蚁的农耕方式至少是可持续性的。
它们不会破坏环境，也不需要使用大量能源。
而且，最近的证据表明，蚂蚁的农耕方式可能比过去我们所认为的还要成熟和灵活。
蚂蚁早于人类5000万年就已成为农夫。
它们不能消化叶子中的纤维素，但是某些真菌可以。
因此蚂蚁在巢穴里培育这些真菌，让它们以叶子为食，而真菌则成为蚂蚁的食物来源。
蚂蚁农夫们分泌抗生素去控制其他可能成为“杂草”的真菌，还会播撒废料来给作物施肥。
剑桥雅思阅读7真题解析pdf精选
剑桥雅思阅读7真题解析pdf精选reading passage 1you should spend about 20 minutes on questions 1-13, which are based on reading passage 1 below.let’s go batsb bats have an engineering problem: how to find their way and find their prey in the absence of light. bats are not the only creatures to face this difficulty today. obviously thenight-flying insects that they prey on must find their way about somehow. deep-sea fish and whales have little or no light by day or by night. fish and dolphins that live in extremely muddy water cannot see because, although there is light, it is obstructed and scattered by the dirt in the water. plenty of other modern animals make their living in conditions where seeing is difficult or impossible.c given the questions of how to manoeuvre in the dark, what solutions might an engineer consider? the first one that might occur to him is to manufacture light, to use a lantern or a searchlight. fireflies and some fish (usually with the help of bacteria) have the power to manufacture their own light, but the process seems to consume a large amount of energy. fireflies use their light for attracting mates. this doesn’t require a prohibitive amount of energy: a male’s tiny pinprick of lightcan be seen by a female from some distance on a dark night, since her eyes are exposed directly to the light source itself. however, using light to find one’s own way around requires vastly more energy, since the eyes have to detect the tiny fraction of the light that bounces off each part of the scene. the light source must therefore be immensely brighter if it is to be used as a headlight to illuminate the path, than if it is to be used as a signal to others. in any event, whether or not the reason is the energy expense, it seems to be the case that, with the possible exception of some weird deep-sea fish, no animal apart from man uses manufactured light to find its way about.questions 1-5reading passage 1 has five paragraphs, a-e.which paragraph contains the following information?write the correct letter, a-e, in boxes 1-5 on your answer sheet.nb you may use any letter more than once.1 examples of wildlife other than bats which do not rely on vision to navigate by2 how early mammals avoided dying out3 why bats hunt in the dark4 how a particular discovery has helped our understanding of bats5 early military uses of echolocationquestions 6-9choose one word only from the passage for each answer.write your answers in boxes 6-9 on your answer sheet.facial visionquestions 10-13choose no more than two words from the passage for each answer.write your answers in boxes 10-13 on your answer sheet.10 long before the invention of radar, …………… had resulted in a sophisticated radar-like system in bats.11 radar is an inaccurate term when referring to batsbe cause………… are not used in their navigation system.12 radar and sonar are based on similar ………… .13 the word ‘echolocation’ was first used by someone working as a ……… .reading passage 2you should spend about 20 minutes on questions 14-26, which are based on reading passage 2 on the following pages.questions 14-20reading passage 2 has seven paragraphs, a-h.choose the correct heading for paragraphs a and c-h from the list of headings below.write the correct number, i-xi, in boxes 14-20 on your answer sheet.list of headingsi scientists’ call for a revision of policyii an explanation for reduced water useiii how a global challenge was metiv irrigation systems fall into disusev environmental effectsvi the financial cost of recent technological improvementsvii the relevance to healthviii addressing the concern over increasing populationsix a surprising downward trend in demand for waterx the need to raise standardsxi a description of ancient water supplies14 paragraph aexample answerparagraph b iii15 paragraph c16 paragraph d17 paragraph e18 paragraph f19 paragraph g20 paragraph hmaking everydrop counta the history of human civilisation is entwined with the history of the ways we have learned to manipulate water resources. as towns gradually expanded, water was brought from increasingly remote sources, leading to sophisticated engineering efforts such as dams and aqueducts. at the height of the roman empire, nine major systems, with an innovative layout of pipes and well-built sewers, supplied the occupants of rome with as much water per person as is provided in many parts of the industrial world today.b during the industrial revolution and population explosion of the 19th and 20th centuries, the demand for water rosedramatically. unprecedented construction of tens of thousands of monumental engineering projects designed to control floods, protect clean water supplies, and provide water for irrigation and hydropower brought great benefits to hundreds of millions of people. food production has kept pace with soaring populations mainly because of the expansion of artificial irrigation systems that make possible the growth of 40 % of the world’s food. nearly one fifth of all the electricity generated worldwide is produced by turbines spun by the power of falling water.c yet there is a dark side to this picture: despite our progress, half of the world’s population still suffers, with water services inferior to those available to the ancient greeks and romans. as the united nations report on access to water reiterated in november 2001, more than one billion people lack access to clean drinking water; some two and a half billion do not have adequate sanitation services. preventable water-related diseases kill an estimated 10,000 to 20,000 children every day, and the latest evidence suggests that we are falling behind in efforts to solve these problems._underground stores of water。
