剑桥雅思4 G类 TestB Section3阅读答案解析

第28题答案:vi

对应原文:A部分:For bees are arguably the only animals apart from humans which have their own language.

答案解析:A部分一开始先介绍了蜜蜂大脑中所包含的数量巨大的行为模式,然后又说它们可能是人类之外唯一拥有自己语言的物种。最后还提到Karl von Frisch因为研究蜜蜂的行为而获得了诺贝尔奖。也就是说三句话都在讲蜜蜂语言/行为的特殊性,由此确定vi为正确答案。

第29题答案:iv

对应原文:B部分:Von Frisch realized that, in some way, messages were being passed on back at the hive, messages which said, ‘Out there, at this spot, you’re going to find food.’

答案解析:B部分主要在讲Von Frisch的研究起源,即他通过前人的研究认识到,蜜蜂通过某种方式向蜂巢传递了信息。选项中只有iv的描述与此相符(communicate对应messages,discovers对应realized),由此确定其为正确答案。

第30题答案:x

对应原文:C部分:He found that, once the scout bees arrived back at the hive, they would perform one of three dance types.

答案解析:这道题比较简单。段落一开始就提到von Frisch发现了蜜蜂的三种舞蹈。随后的内容都在详细阐述这三种舞蹈,由此确定x为正确答案。

第31题答案:viii

对应原文:D部分:Experimenting further, von Frisch unraveled the mystery of the first two related types, the round and the sickle dances.

答案解析:D部分主要在介绍前两种舞蹈类型所起的作用。哪怕我们看不太懂后面的内容,根据first two related types也可以很容易确定viii为答案。

第32题答案:vii

对应原文:E部分:On a hunch, he started gradually moving the feeding dish further and further away and noticed as he did so, that the dances of the returning scout bees also started changing.

答案解析:E部分中间提到,随着他把食物放的越来越远,蜜蜂的舞蹈也开始发生变化。即通过舞蹈来表达具体的距离,由此确定vii为正确答案。

第33题答案:ii

对应原文:F部分:The outside dance was fairly easy to decode: the straight portion of the dance pointed directly to the food source, this article is from website, so the bees would merely have to decode the distance message and fly off in that direction to find their food.

答案解析:F部分一开始提到蜂巢内和文章来自蜂巢外的两种舞蹈,随后将重心放在解释蜂巢外舞蹈的目的上,而将蜂巢内的舞蹈放在了最后一段。由此确定答案为ii。

第34题答案:v

对应原文:G部分:But by studying the dance on the inner wall of the hive, von Frisch discovered a remark-able method which the dancer used to tell her sisters the direction of the food in relation to the sun.

答案解析:这一部分主要在描述蜂巢内舞蹈的目的,即指示食物相对于太阳的方向,由此确定v为正确答案。

第35-37题答案:round, sickle, waggle

对应原文:D部分:Experimenting further, von Frisch unravelled the mystery of the first two related types, the round and the sickle dances.

E部分:But once he moved it past 36 metres, the scouts would then start dancing the third, quite different, waggle dance.

答案解析:C部分虽然完整详细的描述了三种舞蹈的动作,但并没有给出具体的名称,因此我们继续往下寻找。在D部分发现了first two related types这一提示词,然后又在E段发现了the third,由此确定答案为round, sickle, waggle。

第38题答案:the feeding dish

对应原文:E部分:On a hunch, he started gradually moving the feeding dish further and further away and noticed as he did so, that the dances of the returning scout bees also started changing.

答案解析:关于舞蹈模式变化的内容主要集中在E部分。题干中问的是通过改变什么东西的位置,原文里填上去语义合适的只有the feeding dish,由此确定答案(the可带可不带)。

第39题答案:the food (source)

对应原文:F部分:The outside dance was fairly easy to decode: the straight portion of the dance pointed directly to the food source

答案解析:根据outside the hive与outside dance的对应定位到F部分的这句话。空前词point只是变化了下时态,很容易确定答案为the food source。

第40题答案:the sun

对应原文:G部分:However, if, for example, the feeding place is 40° to the left of the sun, then the dancer would run 40° to the left of the vertical line.

答案解析:根据vertical定位到G部分的这句话。从原文可以看出蜂巢内舞蹈指示的主要是食物相对于太阳的位置。angle对应40°,由此确定答案为the sun。
