剑桥雅思9 Test1 Section4听力答案解析
第31题答案：tide/tides
对应原文：this type of event is a frequent occurrence in some of the locations that you’ll be travelling to, where sometimes the tide goes out suddenly, confusing the animals.
答案解析：虽然录音将题干中的common和areas都进行了替换，但这道题真正的难点还在于tide的拼写上。不少同学因为对这个单词不熟悉，再加上/d/的尾音读的比较轻，写成了tight。
第32题答案：hearing/ear/ears
对应原文： For instance, a type of worm is commonly found in the ears of dead whales. Since marine animals rely heavily on their hearing to navigate
答案解析：这道题的两个答案分别对应题干中的两组修饰关系。如果我们将重点文章来自老烤鸭雅思放在空前的所有格上，那么就会找到of结构，进而确定ears为答案。如果我们将重点放在定语从句中的depend on上，就会找到rely on这一组同义替换，由此锁定hearing为答案。
第33题答案：plants animals/fish/fishes
对应原文：Many toxins, as I’m sure you’re aware, originate from plants, or animals
答案解析：这道题比较简单一些。听到toxins意识到答案即将到来。从题干可以推测空上应该填一组并列的单词，由此锁定plants和animals。
第34题答案：feeding
对应原文：this idea does not seem to hold true for the majority of mass strandings because examination of the animals’ stomach contents reveal that most had not been feeding as they stranded
答案解析：听到majority意识到答案即将到来，空前有个not的否定，根据这一点可以锁定feeding。
第35题答案：noise/noises
对应原文： There are also some new theories which link strandings to humans. A growing concern is that loud noises in the ocean cause strandings.
答案解析：雅思听力中，如果空设置在句首，那么我们可以根据上一行结尾或者小标题来定位，进而提示自己答案即将到来。比如这道题我们就可以利用humans。
第36题答案：healthy
对应原文： For one, all the stranded animals were healthy
答案解析：听到all意识到答案即将到来。从题干中可以推测空上应该填一个形容词，再加上healthy明显重读，很容易确定为答案。
第37题答案：group
对应原文：In addition, the animals were spread out along 38 kilometres of coast, whereas it’s more common for the animals to be found in a group when mass strandings occur.
答案解析：虽然题干中的否定在录音中没有出现，但空前介词in保持不变，由此帮助我们确定group为答案。
第38题答案：social
对应原文：This is a particularly interesting theory since the whales that are thought to be most social
答案解析：虽然小标题group behaviour离答案较远，但空前词most原词出现，提示我们social就是答案。
第39题答案：leader
对应原文：Examination of the dead animals revealed that apart from the leader, all the others had been healthy at the time of their death.
答案解析：这道题的同义替换比较精巧，将题干中的only … ill替换为apart from … healthy。不过哪怕我们在听的时候反应不过来，也可以根据重读注意到leader，进而通过句子意思判断它是答案。
第40题答案：network/networks
对应原文：Stranding networks have been established around the world
I recommend John Connor’s Marine Mammals Ashore as an excellent starting point if you’re interested in finding out more about these networks
答案解析：这道题的答案出现了两次，正好对应雅思听力中两种确定答案的方法。其一是修饰关系，根据空前词stranding确定答案为networks；其二为词性和句义，根据Marine Mammals Ashore先缩小范围，然后根据名词锁定networks，最后根据句义流畅判断它就是答案。
