1、雅思（阅读）模拟试卷 69及答案与解析 一、 Reading Module (60 minutes) 0 Adults and children are frequendy confronted with statements about the alarming rate of loss of tropical rainforests. For example, one graphic illustration to which children might readily relate is the estimate that rainforests are being destroyed

2、 at a rate equivalent to one thousand football fields every forty minutes - about the duration of a normal classroom period. In the face of the frequent and often vivid media coverage, it is likely that children will have formed ideas about rainforests - what and where they are, why they are importa

3、nt, what endangers them - independent of any formal tuition. It is also possible that some of these ideas will be mistaken. Many studies have shown that children harbour misconceptions about pure, curriculum science. These misconceptions do not remain isolated but become incorporated into a multifac

4、eted, but organised, conceptual framework, making it and the component ideas, some of which are erroneous, more robust but also accessible to modification. These ideas may be developed by children absorbing ideas through the popular media. Sometimes this information may be erroneous. It seems school

5、s may not be providing an opportunity for children to re-express their ideas and so have them tested and refined by teachers and their peers. Despite the extensive coverage in the popular media of the destruction of rainforests, little formal information is available about childrens ideas in this ar

6、ea. The aim of the present study is to start to provide such information, to help teachers design their educational strategies to build upon correct ideas and to displace misconceptions and to plan programmes in environmental studies in their schools. The study surveys childrens scientific knowledge

7、 and attitudes to rainforests. Secondary school children were asked to complete a questionnaire containing five open-form questions. The most frequent responses to the first question were descriptions which are self-evident from the term rainforest. Some children described them as damp, wet or hot.

8、The second question concerned the geographical location of rainforests. The commonest responses were continents or countries: Africa(given by 43% of children), South America(30%), Brazil(25%). Some children also gave more general locations, such as being near the Equator. Responses to question three

9、 concerned the importance of rainforests. The dominant idea, raised by 64% of the pupils, was that rainforests provide animals with habitats. Fewer students responded that rainforests provide plant habitats, and even fewer mentioned the indigenous populations of rainforests. More girls(70%)than boys

10、(60%)raised the idea of rainforest as animal habitats. Similarly, but at a lower level, more girls(13%)than boys(5%)said that rainforests provided human habitats. These observations are generally consistent with our previous studies of pupils views about the use and conservation of rainforests, in w

11、hich girls were shown to be more sympathetic to animals and expressed views which seem to place an intrinsic value on non-human animal life. The fourth question concerned the causes of the destruction of rainforests. Perhaps encouragingly, more than half of the pupils(59%)identified that it is human

12、 activities which are destroying rainforests, some personalising the responsibility by the use of terms such as we are. About 18% of the pupils referred specifically to logging activity. One misconception, expressed by some 10% of the pupils, was that acid rain is responsible for rainforest destruct

13、ion; a similar proportion said that pollution is destroying rainforests. Here, children are confusing rainforest destruction with damage to the forests of Western Europe by these factors. While two firths of the students provided the information that the rainforests provide oxygen, in some cases thi

14、s response also embraced the misconception that rainforest destruction would reduce atmospheric oxygen, making the atmosphere incompatible with human life on Earth. In answer to the final question about the importance of rainforest conservation, the majority of children simply said that we need rain

15、forests to survive. Only a few of the pupils(6%)mentioned that rainforest destruction may contribute to global warming. This is surprising considering the high level of media coverage on this issue. Some children expressed the idea that the conservation of rainforests is not important. The results o

16、f this study suggest that certain ideas predominate in the thinking of children about rainforests. Pupils responses indicate some misconceptions in basic scientific knowledge of rainforests ecosystems such as their ideas about rainforests as habitats for animals, plants and humans and the relationsh

17、ip between climatic change and destruction of rainforests. Pupils did not volunteer ideas that suggested that they appreciated the complexity of causes of rainforest destruction. In other words, they gave no indication of an appreciation of either the range of ways in which rainforests are important

18、 or the complex social, economic and political factors which drive the activities which are destroying the rainforests. One encouragement is that the results of similar studies about other environmental issues suggest that older children seem to acquire the ability to appreciate, value and evaluate

19、conflicting views. Environmental education offers an arena in which these skills can be developed, which is essential for these children as future decision-makers.Questions 1-8Do the following statements agree with the information given in Reading Passage 1?In boxes 1-8 on your answer sheet writeTRU

32、mammals comprising whales, dolphins and porpoisesSome of the senses that we and other terrestrial mammals take for granted are either reduced or absent in cetaceans or fail to function well in water. For example, it appears from their brain structure that toothed species are unable to smell. Baleen

33、species, on the other hand, appear to have some related brain structures but it is not known whether these are functional. It has been speculated that, as the blowholes evolved and migrated to the top of the head, the neural pathways serving sense of smell may have been nearly all sacrificed. Simila

34、rly, although at least some cetaceans have taste buds, the nerves serving these have degenerated or are rudimentary.The sense of touch has sometimes been described as weak too, but this view is probably mistaken. Trainers of captive dolphins and small whales often remark on their animals responsiven

35、ess to being touched or rubbed, and both captive and free-ranging cetacean individuals of all species(particularly adults and calves, or members of the same subgroup)appear to make frequent contact. This contact may help to maintain order within a group, and stroking or touching are part of the cour

36、tship ritual in most species. The area around the blowhole is also particularly sensitive and captive animals often object strongly to being touched there.The sense of vision is developed to different degrees in different species. Baleen species studied at close quarters underwater - specifically a

37、grey whale calf in captivity for a year, and free-ranging right whales and humpback whales studied and filmed off Argentina and Hawaii - have obviously tracked objects with vision underwater, and they can apparently see moderately well both in water and in air. However, the position of the eyes so r

38、estricts the field of vision in baleen whales that they probably do not have stereoscopic vision.On the other hand, the position of the eyes in most dolphins and porpoises suggests that they have stereoscopic vision forward and downward. Eye position in freshwater dolphins, which often swim on their

39、 side or upside down while feeding, suggests that what vision they have is stereoscopic forward and upward. By comparison, the bot-tlenose dolphin has extremely keen vision in water. Judging from the way it watches and tracks airborne flying fish, it can apparently see fairly well through the air-wa

40、ter interface as well. And although preliminary experimental evidence suggests that their in-air vision is poor, the accuracy with which dolphins leap high to take small fish out of a trainers hand provides anecdotal evidence to the contrary.Such variation can no doubt be explained with reference to

41、 the habitats in which individual species have developed. For example, vision is obviously more useful to species inhabiting clear open waters than to those living in turbid rivers and flooded plains. The South American boutu and Chinese beiji, for instance, appear to have very limited vision, and t

42、he Indian susus are blind, their eyes reduced to slits that probably allow them to sense only the direction and intensity of light.Although the senses of taste and smell appear to have deteriorated, and vision in water appears to be uncertain, such weaknesses are more than compensated for by cetacea

43、ns well-developed acoustic sense. Most species are highly vocal, although they vary in the range of sounds they produce, and many forage for food using echolo-cation1. Large baleen whales primarily use the lower frequencies and are often limited in their repertoire. Notable exceptions are the nearly

44、 song-like choruses of bowhead whales in summer and the complex, haunting utterances of the humpback whales. Toothed species in general employ more of the frequency spectrum, and produce a wider variety of sounds, than baleen species(though the sperm whale apparently produces a monotonous series of

45、high-energy clicks and little else). Some of the more complicated sounds are clearly communicative, although what role they may play in the social life and culture of cetaceans has been more the subject of wild speculation than of solid science.1. echolocation: the perception of objects by means of

46、sound wave echoes.Questions 15-21Complete the table below.Choose NO MORE THAN THREE WORDS from Reading Passage 2 for each answer.Write your answers in boxes 15-21 on your answer sheet.21 Answer the questions below using NO MORE THAN THREE WORDS from the passage for each answer.

48、 best developed in cetaceans? 26 Visual Symbols and the BlindPart 1From a number of recent studies, it has become clear that blind people can appreciate the use of outlines and perspectives to describe the arrangement of objects and other surfaces in space. But pictures are more than literal represe

49、ntations. This fact was drawn to my attention dramatically when a blind woman in one of my investigations decided on her own initiative to draw a wheel as it was spinning. To show this motion, she traced a curve inside the circle(Fig. 1). I was taken aback. Lines of motion, such as the one she used, are a very recent invention in the history of illustration. Indeed, as art scholar David Kunzle notes, Wilhelm Busch, a trend-setting nineteenth-century cartoonist, used virtually no motion lines in his popular figures until about 1877. When I asked several other blind stud
