剑桥雅思9 Test4 Section4听力答案解析
第31题答案：C
对应原文：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
答案解析：选项A和选项B在录音中都没有提到。虽然选项C是正确答案，但其recent phenomenon一词所概括的内容太长（在城市中心花园中看到更多的sparrow hawks），需要较强的句义理解能力才能将两者对应起来。
第32题答案：A
对应原文：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
答案解析：原文中提到，他们通过查询城镇土地调查办公室大比例的地图确认了这一数据。选项A中的official documents对应large-scale usage maps，由此确定答案。B选项中的photos属于无中生有，C选项中的surveyors则是在替换过程中文章来自老烤鸭雅思出现了意思偏差，因此统统排除。
第33题答案：B
对应原文：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 form a list – and adding the names of any rarer ones
答案解析：录音中提到他们要求花园所有者在12个月的时间里，每两周完成一次调查。划掉他们看到的物种，加上任何稀有物种的名字。即记录所看到的动物。这道题的难点跟第31题一样，都是正确选项的概括太过简略，不像是我们平时所熟悉的词汇或短语的同义替换。
第34题答案：B
对应原文：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：这道题要相对简单一些，只要能够抓住typical和representative的同义替换，即可确定B为答案。
第35题答案：A
对应原文：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：这道题进行了大量的同义替换。先是将题干中的extensive reading替换为a lot of books，然后又将animals替换成wildlife，countryside替换成rurual areas，由此确定A为答案。
第36题答案：C
对应原文：What we’ve decided to resent 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：这道题要稍微简单一些，好歹有个because的提示。indicate与indication词性替换，as a whole则对应general trends，由此确定C为答案。而无论是A选项的a lot of data，还是B选项的most interest，在原文中都找不到对应点。
第37题答案：frog/frogs
对应原文：The first species to generate a lot of interesting information was frogs
答案解析：从表头可以推断出空上应该填一种生物。first species有一定的提示作用，帮助我们确定后面的frogs为答案。不过因为这道题离上一道题距离太近，给我们增加了额外的困难。
第38题答案：predators
对应原文：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：听到Hedgehogs意识到答案即将到来，原文对safer进行了词义解释，找不到直接的对应词，只能通过词性和句义来判断答案。
第39题答案：count
对应原文：We had lots of sightings, so all in all we had no difficulties with our efforts to count their numbers precisely
答案解析：空前词easy被替换成no difficulties，从题干可以推测空上应该填一个动词，由此确定答案为count。
第40题答案：seed/seeds
对应原文：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：不少同学会根据空前的a variety of将plants当作答案。但它并不符合空后to eat这一信息点。an extensive range of与a variety of同义替换，feed on与eat同义替换，由此舍弃plants，锁定seeds为答案。
