C
As any plane passenger will confirm, a crying baby is almost impossible to ignore, no matter how hard you try. Now scientists believe they may have worked out why. A baby's cry pulls at the heartstrings (扣人心弦) in a way while other cries don't, researchers found.
Researchers found that a baby's cry can trigger unique emotional responses in the brain, making it impossible for us to ignore them — whether we are parents or not. Other types of cries, including calls of animals in great pain, fail to get the same response, suggesting the brain is programmed to respond specifically to a baby's cry.
A team of Oxford University scientists scanned the brains of 28 men and women as they listened to a variety of calls and cries. After 100 milliseconds — roughly the time it takes to blink (眨眼) — two parts of the brain that respond to emotion lit up. Their response to a baby's cry was particularly strong. The response was seen in both men and women — even if they had no children.
Researcher Dr. Christine Parsons said, "You might read that men should just notice a baby and step over it and not see it, but it's not true. There is a special process in men and women, which makes sense from an evolutionary (进化的) view that both men and women would be responding to these cries." The study was in people who were not parents, yet they were all responding within 100 milliseconds to these particular cries, so this might be a fundamental response present in all of us regardless of parental status.
Fellow researcher Katie Young said it might take a bit longer for someone to recognize their own child's cries because they needed to do more "fine-grained analysis". The team had previously found that our reactions sped up when we heard a baby crying. Adults performed better on computer games when they heard the sound of a baby crying than when they heard recordings of adults crying.

答案： 28.D 细节理解题。根据第一段最后一句“A baby’s cry pulls at the heartstrings in a way while other cries don’t，researchers found.”可知，与其他的哭声相比，婴儿的哭声以一种不同的方式扣人心弦，因此会引起人们强烈的情感共鸣。
29.A 词义猜测题。根据上一段最后一句中的“A baby’s cry pulls at the heartstrings”，再结合画线词所在语境可知，研究人员发现，婴儿的哭声可以在大脑中引发独特的情绪反应，使人们不可能忽视他们的哭声。故trigger意为“引发；引起”，与A项意思相近。
30.C 细节理解题。根据第四段最后一句可知，Christine Parsons的研究对象是那些不是父母的人，但他们对这些特定的哭声的反应都是在100毫秒内，这可能是所有人对婴儿哭声最基本的反应，故Christine Parsons可能会赞同“几乎每个人对婴儿的哭声都有一定的反应”这一说法。
31.D 主旨大意题。研究者们通过研究发现无论是为人父母者还是没有孩子的人都无法忽视婴儿的哭声，所以本文主要讲了为什么无法把婴儿的哭声从脑海中抹去。
