剑桥雅思7 Test2 Section4听力答案解析
第31题答案：C
对应原文：But what I soon became struck by was the sheer volume of both observation and investigation he had done
答案解析：原文中提到，她很快震惊于该作者所进行的观察和研究的数量。选项C中size和volume同义替换，由此确定答案为C。录音中并没有提到她所遭遇的困难，由此排除A，而B选项则不符合题干中first这一限定。
第32题答案：B
对应原文：not so much in helping sportspeople to work on their weaker side, but more that they can help them identify the most suitable strategies to use in a given game.
答案解析：录音中确实提到了A选项，但前面有否定，因此排除。选项B只是将文章来自老烤鸭雅思Help替换为aid，strategies替换为tactics，由此确定答案。C选项完全没提到。
第33题答案：C
对应原文：Although most trainers know how important handedness is, at present they are rather reluctant to make use of the insights scientists like Matthews can give
答案解析：录音中提到，教练指导左右手偏好的重要性，因此排除A；B选项完全没有提到；C选项中underestimate与reluctant同义替换，science与scientists，offer与give同义替换，由此确定答案。
第34题答案：A
对应原文： Also those who started younger were more mixed-handed.
答案解析：选项A只是将录音中的younger替换为early youth，由此确定答案。B选项正好与题干所谓内容相反，弦乐器练得多的话，会更加偏向于一只手。C选项没有他提及。
第35题答案：A
对应原文： Studies showed that apes consistently using the same hand fished out 30% more ants than those varying between the two.
答案解析：录音中提到，一直使用同一只手的猩猩可以捕获更多的蚂蚁，对应A选项中的most successful，由此确定答案。猩猩自身族群中左右手的比例几乎一样，而非跟人类相同，由此排除B和C。
第36题答案：2 directions
对应原文： this is because a hockey stick must be deployed in two directions
答案解析：听到hockey意识到答案即将到来，题干中used与deployed同义替换，in原词出现，由此确定答案为two directions。
第37题答案：confident
对应原文：An interesting finding is that mixed-handed hockey players were significantly more confident than their single-handed counterparts.
答案解析：根据题干可以推测空上应该填一个形容词的比较级，而more在原文中并没有替换，由此确定答案为confident。
第38题答案：vision
对应原文：Here the important thing is to have the dominant hand and eye on the one side. This article is from Laokaoya website. This means that there is a bigger area of vision on the side where most of the action occurs.
答案解析：听到tennis意识到答案即将到来，题干中的larger field与录音中的bigger area同义替换，由此确定答案为vision。
第39题答案：corrections
对应原文：. If a player is cross lateral the racket is invisible from the dominant eye for much of the swing. It means that they can only make corrections much later
答案解析：听到cross意识到答案即将到来，空前词make没有替换，由此锁定corrections。
第40题答案：balance
对应原文：The predominant reason for this is because it aids balance – which is of course absolutely central to performance in this sport.
答案解析：听到gymnastics意识到答案将到来，不过题干上的空前后词并没有什么提示作用，只能根据词性注意到balance，然后在根据录音后面的central与important的同义替换确定答案。
