1．阅读理解
    When a dog looks at you with big puppy-dog eyes, it's hard for you to go away, and you may speak out “Awww” without hesitation. However, there's a reason why you find a dogs stare so attractive. That sweet stare actually causes the release of a particular hormone, or chemical messenger in the body. This hormone creates feelings of affection in humans. The same thing happens to dogs when people look back at them. Scientists believe this helps people and their four-legged friends bond, or feel connected. Scientists have wondered what causes dogs to lovingly stare at their owners. To find out, a team of researchers from Azabu University in Japan studied 30 owners and their dogs.
    The researchers found that after the pets and their owners spent half an hour together, both showed a rise in oxytocin (催产素). One key role of this hormone in many animals is to p
romote bonding, like that between a mother and newborn. The increase of oxytocin didn't happen, though, when scientists repeated the experiment with wolves and the humans who had raised them.
    A second experiment also found that if dogs were given oxytocin, they looked at their owners longer. Scientists aren't sure exactly why, but this reaction occurred only with female dogs. Their owners oxytocin levels also rose as a result.
    The result of these experiments might help answer an age-old question: How did the fearsome wolf ancestor of modern dogs turn into man's best friend? Takefumi Kikusui, an animal scientist who worked on the study, thinks that the change happened when dogs first became domestic (驯养的).
    According to Kikusui, there may have been a small group of wild dogs that were naturally friendlier. “Humans are very sensitive to eye contact. By using this special communication tool, the dogs are able to win over our hearts. If they are more likely to make eye contact, it would be easier for them to bond with dog owners,” Kikusui said.

【答案】（1）B
（2）C

（4）D 
【解析】【分析】本文为应用文。本文主要叙述科学家解开了狗与人类的关系为何演变成今日如此这般和谐的原因之谜。
（1）推理判断题。第一段开头When a dog looks at you with big puppy-dog eyes, it's hard for you to go away, and you may speak out “Awww” without hesitation. However, there's a reason why you find a dogs stare so attractive.当狗看着你，你毫不犹豫地说“Awww”，不愿意离开。这是因为你觉得狗的注意力很有吸引力，狗吸引了你，说明你爱狗。故答案选B。
（2）细节理解题。根据第二段开头的…after the pets and their owners spent half an hour together, both showed a rise in oxytocin (催产素). One key role of this hormone in many animals is to promote bonding, …宠物和主人在一起半个小时，人与狗身上的催产素就会增加了。这种激素在许多动物中的关键作用就是促进关系。说明，催产系可以帮助动物加强联系，提升关系。故答案选C。
（3）推理判断题。第三、四两段给狗催产素，它们注视主人时间更长。但是只有母狗会如此，所以给狗催产素后，狗的反应不一样。这些实验的结果可能有助于解决一个古老的问题：现代狗的可怕狼祖先是如何变成人类最好的朋友的？从事这项研究的动物科学家Takefumi Kikusui认为，这种变化就是狗最初成为家畜时发生的变化。由此可推断出，这种变化就是狗由令人害怕的狼祖先变成人类最好的朋友。分析选项可知，故答案选A。
（4）主旨大意题。通读全文可知，本文解释了狗与人类的关系如何演变成今天的如此和谐的朋友关系的原因。分析选项可知D项（解释人类和狗连系的原因）符合题意，故答案选D。
【点评】阅读理解题主旨大意及段落大意解题技巧：
位于段首：一般而言，以演绎法撰写的文章，主题句往往在文章的开头，即先点出主题，然后围绕这一主题作具体的陈述。
位于段尾：有些文章会在开头列举事实, 然后通过论证阐述作者的核心论点。
位于段中：有时段落是先介绍背景和细节，接着用一句综合或概括性的话概括前面所说的内容或事例，然后再围绕主题展开对有关问题的深入讨论。
首尾呼应：主题句在段落的开头和结尾两个位置上先后出现，形成前呼后应的格局。

    It has been discovered that after the age of sixteen, the number of our brain cells begins
to decrease at a speed of several million a year. They simply die off. In certain types of activity, the human brain is at its highest point in the early twenties, when it has collected enough information to be able to use the vast number of cells freely in the most effective way. Pure mathematics is one of the fields in which this happens, and we know that Albert Einstein made all his world-shaking discoveries between the age of about 20 and 25, and spent the rest of his life tidying them up and arranging them.
