19.Using the term"bird brain"is one way to look down upon another person's intelligence.That is because a bird's brain is small.So,anyone with such a bird-sized brain was thought to be not that intelligent.
But calling some one a bird brain might not be as offensive as it once was.That finding comes from a study of the mental abilities of birds.
Two European scientists reported that at least two kinds of birds-crows and parrots-can think logically.A crow or parrot can recognize itself when the bird sees its image in a mirror.The scientists say crows and parrot also can feel empathy.In other words,they are able to understand and share the experiences and emotions of other birds.According to researchers,these abilities are"as complex and diverse as those of apes(猿)".
However,the brains of birds and those of apes are different.The brain of a bird does not have a neocortex (新大脑皮层).The neocortex controls thinking and remembering.A bird brain is also much smaller than the brain of a monkey or other apes.
So why can birds perform as well as mammals in some activities?
Researchers in Germany suggest that different methods of complex thinking developed independently in birds and mammals.The researchers found that the brains of birds and mammals do have different structures.But there are also similarities in the brain architecture.The brains of both creatures have what is called a pre-frontal (前额叶) structure that controls similar high-level functions.They reported their findings in the journal Trends in Cognitive Sciences.

分析 文章主要讲述了人们以前普遍认为鸟类是最愚蠢的,这篇文章通过科学家的一些实验证明了鸟类并不是最愚笨的.
解答 32.A 句意理解题.根据文章第一段第一句"Using the term"bird brain"is one way to look down upon another person's intelligence.That is because a bird's brain is small"用"鸟脑"这个词是轻视别人智慧的一种方式,那是因为鸟的大脑很小,可知.划线部分的意思指的是没有比鸟更聪明的生物.故选A.
33.C 推理判断题.根据文章内容"they are able to understand and share the experiences and emotions of other birds."他们能够理解和分享其他鸟类的经历和情感,可知,作者提到乌鸦和鹦鹉的目的是说明鸟类不像人们认为的那么的愚蠢.故选C.
34.B 细节理解题.根据文章内容"the brains of birds and those of apes are different.The brain of a bird does not have a neocortex (新大脑皮层).The neocortex controls thinking and remembering."鸟的大脑与猿类不同.一只鸟的大脑没有新皮层大脑皮层控制思考和记忆.故选B.
35.A 细节理解题.根据文章内容"The brains of both creatures have what is called a pre-frontal (前额叶) structure that controls similar high-level functions."可知,鸟类能像哺乳动物一样有些活动是因为他们有相似的大脑结构与前额叶的结构.故选A.
点评 做这类题材阅读理解时要求考生对文章通读一遍,做题时结合原文和题目有针对性的找出相关语句进行仔细分析,结合选项选出正确答案.推理判断题也是要在抓住关键句子的基础上合理的分析才能得出正确答案,切忌胡乱猜测,一定要做到有理有据.
