剑桥雅思13 Test3 Passage2阅读答案解析
第14题答案：B
对应原文：D段：says Nairán Ramírez-Esparza of the University of Connecticut. ‘We also found that it really matters whether you use baby talk in a one-on-one context,’ she adds.
答案解析：人名观点匹配类的题目反过来做会简单一些，即先在原文中圈出人名所在的地方，然后再看题干中的信息属于哪个人的观点。
题干中的importance与really matters对应，individual attention与one-on-one context对应，由此确定答案为B。
第15题答案：C
对应原文：F段：The results suggest that listening to baby talk prompts infant brains to start practicing their language skills … says co-author Patricia Kuhl
答案解析：F段中间提到，听儿语可以促进婴儿大脑开始锻炼他们自己的语言能力。其中connection对应promps，listening对应hear，create speech对应praticing their language skills，由此确定A为答案。
第16题答案：A
对应原文：C段：‘The idea is that a kid gets to practice a certain kind of speech with mom and another kind of speech with dad, so the kid then has a wider repertoire of kinds of speech to practice,’ says VanDam.
答案解析：C段最后提到，孩子跟妈妈联系一种语言，跟爸爸联系另一种语言，这样一来，孩子随后会拥有更广泛的语料库来练习。即父母双方以不同方式说话的好处，由此确定C为正确答案。
第17题答案：B
对应原文：D段： The study found that the more baby talk parents used, the more their youngsters began to babble … says Nairán Ramírez-Esparza
答案解析：D段第二句提到，研究发现，父母使用的儿语较多，他们的孩子也会咿呀学语的越多。即孩子听到的儿语数量与他们自己说话数量的联系。由此确定B为答案。
第18题答案：recording devices
对应原文：C段：Mark VanDam of Washington State University at Spokane and colleagues equipped parents with recording devices and speech-recognition software …
答案解析：根据Washington State University定位到C段的这句话。从题干可以看出，空上应该填一种物品，而且还要与software并列，符合这一条件的只有recording devices。
第19题答案：fathers/dads
对应原文：C段：Dads didn’t raise their pitch or fundamental frequency when they talked to kids.
答案解析：顺着上一题往下，发现modify their ordinary speech patterns对应不提高他们的音调或者基础频率，由此确定dads为正确答案。
第20题答案：bridge hypothesis
对应原文：C段：Their role may be rooted in what is called the bridge hypothesis, which dates back to 1975.
答案解析：一般而言，当题干中空前提示词为known as时，答案一般为某种专业的理论或者专有名词，再加上known as与called同义替换，由此确定答案为bridge hypothesis。
第21题答案：repertoire
对应原文：C段：The idea is that a kid gets to practice a certain kind of speech with mom and another kind of speech with dad, so the kid then has a wider repertoire of kinds of speech to practice
答案解析：题干中的内容在16题已经有所考察，因此定位没有任何难度。expands与wider对应，types与kings对应，根据修饰关系确定答案为repertoire。
第22题答案：(audio-recording) vests
对应原文：D段：Scientists from the University of Washington and the University of Connecticut … fitting 26 children with audio-recording vests
答案解析：根据两所大学的名字定位到D段的第一句话。从题干可以看出空上填的应该是某种设备，再加上with与using的同义替换，由此确定答案为audio-recording vests。
第23题答案：vocabulary
对应原文：D段：when researchers saw the same babies at age two, they found that frequent baby talk had dramatically boosted vocabulary, regardless of socioeconomic status.
答案解析：根据年龄age two定位到这句话。从题干文章来自老烤鸭雅思可以看出空上应该填一个名词，larger又与boosted同义替换，由此确定答案为vocabulary。
第24题答案：F
对应原文：F段：In a study published in Proceedings of the National Academy of Sciences, a total of 57 babies from two slightly different age groups – seven months and eleven and a half months …
答案解析：这道题的解题关键在于before the end of their first year。虽然文章通篇都在讲婴儿语言的事情，但只有F段提到了1岁以前的年龄，由此确定答案为F。
第25题答案：A
对应原文：A段：Most babies start developing their hearing while still in the womb, prompting some hopeful parents to play classical music to their pregnant bellies.
答案解析：A段中提到，大多数婴儿还在子宫里的时候就发育出听觉，促使一些满怀希望的父母对着他们怀孕的肚子播放古典音乐。对应题干中家长在孩子出生前所做的事情，由此确定A为答案。
第26题答案：E
对应原文：E段：They found that the ‘infant’ sounds held babies’ attention nearly 40 percent longer.
答案解析：E段中部提到，婴儿的声音可以让孩子保持关注的时间长出将近40%。即婴儿更喜欢其他婴儿发出的声音，由此确定答案。
