Evidence from brain imaging supports this view. The brain is as active during REM (rapid eye movement) sleep -- when most vivid dreams occur -- as it is when fully awake, says Dr, Eric Nofzinger at the University of Pittsburgh. But not all parts of the brain are equally involved; the limbic system (the “emotional brain”) is especially active, while the prefrontal cortex (the center of intellect and reasoning) is relatively quiet. “We wake up from dreams happy or depressed, and those feelings can stay with us all day.” says Stanford sleep researcher Dr. William Dement.
The link between dreams and emotions shows up among the patients in Cartwright’s clinic. Most people seem to have more bad dreams early in the night, progressing toward happier ones before awakening, suggesting that they are working through negative feelings generated during the day. Because our conscious mind is occupied with daily life we don’t always think about the emotional significance of the day’s events -- until, it appears, we begin to dream.
-------------2005年考研英语阅读真题text3 passage2&3
32.By referring to the limbic system, the author intends to show ________________________.
[A] its function in our dreams
[B] the mechanism of REM sleep
[C] the relation of dreams to emotions
[D] its difference from the prefrontal cortex
正确答案:C
详解:
本题是细节题。细节题需要的是回归原文找细节,但是细节必须服从文章主旨。唯有这样的答案才是正确的答案。
根据题干 limbic system,我们找到But not all parts of the brain are equally involved; the limbic system (the “emotional brain”) is especially active, while the prefrontal cortex (the center of intellect and reasoning) is relatively quiet. 但该句话并没有涉及写limbic system的目的问题。那么看看该句前面的内容:讲的是在REM中,大脑非常活跃。
貌似在陈述事实,也没有出现limbic system。说明我们定位的地方就是**次出现limbic system的地方,那么其作用应该在后面:“We wake up from dreams happy or depressed, and those feelings can stay with us all day.”我们或快乐或沮丧地从睡梦中醒来,这些情绪可以伴随我们一天。从这句话中,我们可以总结出在limbic system 非常活跃的梦中,我们会有或喜或悲的情感。因而作者的目的应该是想要揭示梦与情绪的关系。C为正确选项。此外,有一个小细节我们不能忽视limbic system (the “emotional brain”) ,括号里叫limbic system 是emotional brain,是人的情绪大脑,说明它的另一个称号的作用是与emotional 有关的,因而即便是后面没有分析太懂,这个小括号里面的信息也暗示你了,作者要开始讲梦与情绪之间的关系了。
再者,我们继续浏览下一段。下一段**句话就开始出现:The link between dreams and emotions ,该段段首显然是总结了二段的内容,起到了一个承上启下的作用。如此,有三处确认,答案C毕对无疑。
我们再来看一下其它选项为什么错:
A 目的是想要展示它在梦中的作用。文中说道它在梦中非常活跃,是emotional brain ,也就是它的作用,是引起在梦中的情绪波动。看似A说的非常对。但是这不是作者强调的重点,文中直接说limbic system (emotional brain),直接告诉你了,作用emotional,可见其目的不是说它的作用,而是以emotional brain 为代表的梦对人产生的影响。而且通篇也没有提到limbic system 的具体的function 方面。此外,这一点太细,与中心主旨无关,也不能选。B想要展示REM睡眠的机理,也是犯了无中心主旨这个错误。D 与prefrontal cortex的区别,也是太细,无关宏观主旨。
总结:遇到这样的细节题,首先根据题干进行**次定位,找到解题大致区间;然后前瞻后顾,第二次定位,找到预选答案;时刻谨记文章主旨,细节服从主旨,与此相关方为最佳答案。 针对本题还有一个细节需要提醒:“()”, “— —”,里的内容**次浏览文章不需要详细看,但是如若出题定位到含有括号,破折号(都是起到解释说明的作用)的句子,那么括号破折号里面的内容一定要认真理解,说不定就暗含着题目的答案。
