剑桥雅思4 Test 2阅读Passage 3解析
第27题答案：H
对应原文：H段：By allowing link-ups between brain areas that might not normally communicate with each other, play may enhance creativity.
解析：题干中的unusaual, connections, beneficial分别与not normally, link-ups和enhance creativity对应，因此确定答案为H
第28题答案：F
对应原文：F段：the timing of the playful stage in young animals provides an important clue to what’s going on. If you plot the amount of time a juvenile devotes to play each day over the course of its development…
解析：题干中的词汇依次与原文中的clue, plot, the amount of, juvenile, devote to对应，由此确定答案为F
第29题答案：A
对应原文：A段： For a start, play can even cost animals their lives. Eighty per cent of deaths among juvenile fur seals occur because playing pups fail to spot predators approaching.
解析：文中指出80%海豹幼崽的死亡都是由于玩耍的时候没有注意到捕食者的接近，等于说是具体解释了题干中的physical hazards，因此确定答案为A
第30题答案：H
对应原文：H段：He points out that play often involves complex assessments of playmates, ideas of reciprocity and the use of specialised signals and rules.
解析：文中所说的对玩伴的评估，对互惠的认知，和对信号与规则的使用就是题干中mental activities的具象化，而且它们都得到了锻炼，因此确定答案为H
第31题答案：I
对应原文：I段：What might further experimentation suggest about the way children are raised in many societies today? We already know that rat pups denied the chance to play grow smaller brain components and fail to develop the ability to apply social rules when they interact with their peers.
解析：文章虽然只是提出玩耍时间减少对儿童有影响的疑问，但下面举了小老鼠的例子来说明它的不良后果，与题干中的possible effects对应，因此确定答案为I
第32题答案：B
对应原文：B段：Playfulness, it seems, is common only among mammals, although a few of the larger-brained birds also indulge.
解析：这道题的难点在于对classes的理解。它除了班级之外，还有类别的意思。由此很容易确定答案是B
第33题答案：A
对应原文：B段：A popular explanation of play has been that it helps juveniles develop the skills they will need to hunt, mate and socialise as adults.
解析：rehearsal是排练的意思，对应原文中帮助动物幼崽提升技能，由此确定答案是A
第34题答案：C
对应原文：B段：Another has been that it allows young animals to get in shape for adult life by improving their respiratory endurance.
解析：build up strength与get in shape同义替换，都是锻炼身体，增强力量的意思，因此确定答案为C
第35题答案：F
对应原文：E段：Earlier this year, Sergio Pellis of Lethbridge University, Canada, reported that there is a strong positive link between brain size and playfulness among mammals in general.
解析：文中指出玩耍与大脑的尺寸存在正相关的关系，即玩耍越多，大脑越大，因此对应题干中文章来自老烤鸭雅思所说的“有助于器官增长的活动”。
第36题答案：B
对应原文：E段：Robert Barton…‘I concluded it’s to do with learning, and with the importance of environmental data to the brain during development,’
解析：根据人名定位E段，原文中的environment与B选项中的Physical surrounding同义替换，由此确定答案为B
第37题答案：G
对应原文：G段：Bekoff likens it to a behavioural kaleidoscope, with animals at play jumping rapidly between activities.
解析：根据人名定位到G段，原文中kaleidoscope为万花筒的意思，知道这一点之后很容易对应G选项的a wide range。如果不认识的话也没关系，后面一句话也说了动物在不同活动之间快速切换，同样能够因此选出G。
第38题答案：E
对应原文：C段：But Byers points out that the benefits of increased exercise disappear rapidly after training stops, so any improvement in endurance resulting from juvenile play would be lost by adulthood.
解析：根据人名定位到C段，原文中指出幼年时期锻炼得到的好处到成年阶段就会消失。这与E选项所说的“玩耍不是为了未来而进行的身体锻炼”相对应，因此确定答案。
第39题答案：D
对应原文：E段：Sergio Pellis of Lethbridge University, Canada, reported …larger brains (for a given body size) are linked to greater playfulness. The converse was also found to be true.
解析：根据人名定位到E段。文中先指出较大的大脑与更多的玩耍联系在一次，然后又说相反的规律也是正确的。即玩耍更少跟更小的大脑相关。因此确定D为答案。
第40题答案：A
对应原文：H段：Siviy studied how bouts of play affected the brain’s levels of a particular chemical associated with the stimulation and growth of nerve cells.
解析：文中的particular chemical与A选项中的specific substance同义替换，其他单词也能够在原文中找到对应点，由此确定答案为A。
