We are often told to pay attention to what our mothers tell us. Most of us enjoy listening to our mothers speaking. Scientists at Stanford University, US have found that compared to other people’s voices, our brains react strongly to our mother’s voices.
The scientists examined 24 children aged 7 to 12 and asked their mothers as well as two mothers whose children were not studied to record three nonsense words.“In this age period,  most children have good language skills. We didn’t want to use words that had meaning because that would have involved(涉及) many different parts in the brain,”said Professor Menon.
The children’s brains were scanned while they listened to the nonsense-word recordings, produced by their own mother and other mothers. Even from very short recordings, less than a second long, the children could make sure of their own mother’s voice with greater than 97 percent accuracy(正确率). Hearing their mother’s voice makes many parts of children’s brains more active, including those about positive emotion and social communication.
Years of study has shown that children prefer their mothers’ voices and it starts even before they’re born. When children are still in the womb (子宫) or have just been born they hear their mothers talking. This makes babies feel comfortable and safe and teaches them language and social skills, even though they are still very young. Later, when this sound is heard again, more attention is paid to it.

A. ①②③ B. ③①② C. ①③② D. ②③①
34. Why do children pay more attention to their mothers’ voices?
A. Because they can get a prize for doing so.
B. Because they enjoy listening to their mothers’ voices.

解析
【分析】
这是一篇说明文。斯坦福大学科学家们通过调查研究,发现我们的大脑对自已母亲的声音的反应非常强烈,因为自从出生前在母亲的子宫里时,我们就感受到了母亲的声音,它使我们感到舒适并学习知识与技能。
【32题详解】
细节理解题。根据第二段句子“The scientists examined 24 children aged 7 to 12 and asked their mothers as well as two mothers whose children were not studied to record three nonsense words.”(科学家们检查了24位7至12岁的孩子,让他们的母亲以及另外2个没有被研究的孩子的母亲去录制3句荒谬的话)可知,共有26位母亲参与录制语音。故选C。
【33题详解】
细节理解题。根据第三段句子“The children’s brains were scanned while they listened to the nonsense-word recordings, produced by their own mother and other mothers. … the children could make sure of their own mother’s voice with greater than 97 percent accuracy(正确率).”(当孩子们听这些录制了他们自己母亲及别人母亲的3句荒谬的话时,他们的大脑被扫描仪扫描,……孩子们有97%以上的正确率能确认出他们自己母亲的声音。)可知,这三件事先后为:母亲录制3句荒谬的话——孩子们听的时候,科学家扫描大脑——孩子们确认自己母亲的声音。故选B。
【34题详解】
细节理解题。根据末段句子“When children are still in the womb (子宫) or have just been born, they hear their mothers talking. This makes babies feel comfortable and safe and teaches them language and social skills, even though they are still very young.”(当孩子还在子宫或者刚刚出生时,他们就听妈妈说话的声音。这使婴儿觉得安全舒适,也教他们语言和社会技能,即使在他们非常小的时候)可知,孩子更加注意妈妈是声音是因为他们可以学到东西并觉得舒适。故选C。
【35题详解】
推理判断题。根据第一段句子“Scientists at Stanford University, US have found that…(美国斯坦福大学的科学家发现......)”、第二段句子“The scientists examined…(科学家们检查......)”以及末段“Years of study has shown that…(几年的研究表明)”可知,本文主要讲述的是一个与母亲声音对孩子成长的影响的科学研究,即与科学相关。故选A。
【点睛】本文涉及到科学研究及相关方法。阅读时,仍要抓段中的主题句与关键词,明确被研究的对象,研究目的与方法。
