剑桥雅思9Test4听力Section4答案及解析

**Listening Section 4, Questions 31-36** **31.** What led the group to choose their topic? A They were concened about the decline of one species. B They were interested in the effects of city growth. C They wanted to investigate a recent phenomenon. 答案：C 题干翻译：是什么使得小组选择他们的主题？ 解题思路：本题问的是小组选题的原因，选项的关键词分别是 decline，effects和recent phenomenon，可以根据关键词进行快速判断。 答案原文：First of all, how did we choose our topic? Well, there are four of us in the group and one day while we were discussing a possible focus, two of the group mentioned that they had seen yet more sparrow-hawks, one of Britain's most interesting birds of prey, in their own city centre gardens and wondered why they were turning up in these gardens in great numbers. We were all very engaged by the idea of why wild animals would choose to inhabit a city garden. Why is it so popular with wildlife when the countryside itself is becoming less so? 答案解析：根据原文how did we choose our topic可知，后面的内容即为解释进行选题的原因。根据they were turning up in these gardens in great numbers可知，选项B的city growth和原文不符，增长的不是城市，而是城市中食雀鹰的数量，B错误；A选项没有提到，而原文这一段都是在讲recent phenomenon，所以本题答案是C。 **32.** The exact proportion of land devoted to private gardens was confirmed by A consulting some official documents. B taking large-scale photos. C discussions with town surveyors. 答案：A 题干翻译：私人花园用地的确切比例由 解题思路：本题问的是exact proportion是由什么决定的，注意听和exact proportion有关的内容。 答案原文：The first thing we did was to establish what proportion of the urban land is taken up by private gardens. We estimated that it was about one fifth, and this was endorsed by looking at large-scale usage maps in the town land survey office, 24% to be precise. 答案解析：根据原文what proportion of the urban land is taken up by private gardens可知，题干词proportion原文重现，后面的内容可能为答案。比例是和 large-scale usage maps有关，但并不是B的large-scale photos，B错误；后面的land survey office为官方机构，因此文件一定是官方认可的，而C的town surveyors并没有提到discussion，所以本题答案是A。 **33.** The group asked garden owners to A take part in formal interviews. B keep a record of animals they saw. C get in contact when they saw a rare species. 答案：B 题干翻译：小组要求花园业主 解题思路：本题问的是和garden owners有关的内容，要求garden owners如何做，注意听相关内容。 答案原文： Our own informal discussions with neighbours and friends led us to believe that many garden owners had interesting experiences to relate regarding wild animal sightings so we decided to survey garden owners from different areas of the city. Just over 100 of them completed a survey once every two weeks for twelve months, ticking off species they had seen from a pro forma list and adding the names of any rarer ones. 答案解析：根据原文可知，garden owners在原文中重现，方便定位。后面讲到garden owners需要icking off species they had seen from a pro forma list and adding the names of any rarer ones，原文的ticking和选项B中的keep a record为同义替换，A的interview没有提到，C的get in contact不准确，所以本题答案是B。 **34.** The group made their observations in gardens A which had a large number of animal species. B which they considered to be representative. C which had stable populations of rare animals. 答案：B 题干翻译：那群人在花园里观察 解题思路：本题问的是observations，所以注意听相关内容。 答案原文：Meanwhile, we were doing our own observations in selected gardens throughout the city. We deliberately chose smaller ones because they were by far the most typical in the city. The whole point of the project was to look at the norm not the exception. 答案解析：根据原文 we were doing our own observations in selected gardens可知，题干词observation原文重现，后面的chose smaller ones because they were by far the most typical in the city即为观察的内容，选项B的representative与原文typical为同义替换，所以本题答案是B。 **35.** The group did extensive reading on A wildlife problems in rural areas. B urban animal populations. C current gardening practices. 答案：A 题干翻译：这个小组广泛地阅读了 解题思路：本题问的是group阅读的内容，可以根据group进行判断。 答案原文：Alongside this primary research on urban gardens, we were studying a lot of books about the decline of wild animals in the countryside and thinking of possible causes for this. 答案解析：根据原文可知，题干中的reading应当与原文中的books对应，rural area与原文countryside对应，B的urban animal没有提到，C的gardening practice的意思是园艺操作，也不符合题意，所以本题答案是A。 **36.** The speaker focuses on three animal species because A a lot of data has been obtained about them. B the group were most interested in them. C they best indicated general trends. 答案：C 题干翻译：演讲者把注意力集中在三种动物身上，因为 解题思路：本题题干的关键词是three animal species，所以注意听和three animal species有关的内容。 答案原文：What we've decided to present today is information about just three species because we felt these gave a good indication of the processes at work in rural and urban settings as a whole. 答案解析：根据原文information about just three species可知，后面的内容可能和答案有关。根据good indication of the processes at work in rural and urban settings as a whole可知，good indication...as a whole是就整体情况来讲，这是一个非常好的解释，所以和C的 best indicated相对应，所以本题答案是C。 **questions 37.-40.** **37.** Animals ________ 答案：frog/frogs 题干翻译：动物 _________ 解题思路：本题问的是第一个讲述的动物，所以注意听和first有关的内容，此处填的是动物名称。 答案原文：The first species to generate a lot of interesting information was frogs. 答案解析：根据原文The first species to generate a lot of interesting information was frogs可知，答案直接在原文中给出，所以听到the first时就可以做出判断，本题答案是frog/frogs。 **38.** safer from _______ when in cities 答案：predators 题干翻译：在城市中_______更安全 解题思路：本题问的是和safe有关的内容，本题填的是名词。 答案原文：Hedgehogs are also finding it easier to live in urban areas——this time because their predators are not finding it quite so attractive to leave their rural environment, so hedgehogs have a better survival rate in cities. 答案解析：根据原文可知，Hedgehogs发现it easier to live in urban areas，这是因为because their predators are not finding，正是因为缺少predator，它们才可以在城市更安全生存，所以本题答案是predators。 **39.** easy to ______ them accurately 答案：count 题干翻译：容易更准确地______他们 解题思路：本题问的是更容易做什么，此处填的是动词。 答案原文：We had lots of sightings, so all in all we had no difficulties with our efforts to count their numbers precisely. 解题思路：根据原文we had no difficulties with our efforts to count their numbers可知，很容易count their numbers，原文的had no difficulties和题干的easy相对应，所以本题答案是count。 **40.** a variety of _____ to eat 答案：seed/seeds 题干翻译：各种_____可以吃 解题思路：根据a variety of 可知，此处填的是名词，并且和食物有关。 答案原文：On the decline in the countryside, they are experiencing a resurgence in urban gardens because these days gardeners are buying lots of different plants which means there's an extensive range of seeds around, which is what they feed on. 答案解析：根据原文there's an extensive range of seeds around, which is what they feed on可知，题干a variety of和原文an extensive range是同义替换，题干的eat和原文的feed on是同义替换，即它们的食物来源是seeds，所以本题答案是seed/seeds。
