阅读理解 No one knows for certain why people dream, but some dreams misht be connected to the mental processes that help us learn. In a recent study, scientists found a connection between nap-time (午睡时间) dreams and better memory in people who were learning a new skill. “I was astonished by this finding,” Robert Stickgold told Science News. He is a cognitive neuroscientist at Harvard Medical School who worked on the study of-how the brain and nervous system work, and cognitive studies look at how people learn and reason. So a cognitive neuroscientist may study the brain processes that help people learn.In the study, 99 college students between the ages of 18 and 30 each spent an hour on a computer, trying to get through a virtual maze (虚拟迷宫). The maze was difficult, and the study participants had to start in a different place each time they tried - making it even more difficult. They were also told to find a particular picture of a tree and remember where it was.For the first 90 minutes of a five-hour break, half of the particularity stayed awake and half were told to take a short nap. Participants who stayed awake were asked to describe their thoughts. Participants who took a nap were asked about their dreams before sleep and after steep - and they were awakened within a minute of sleep to describe their dreams.About a dozen of the 50 people who slept said their dreams were connected to the maze. Some dreamed about the music that had been playing when they were working; others said they dreamed about seeing people in the maze. When these people tried the computer maze again, they were generally able to find the tree faster than before their naps. However, people who had other dreams, or people who didn’t take a nap, didn’t show the same improvement.Stickgold suggests the dream itself doesn’t help a person learn - it’s the other way around.1.It is a cognitive scientists job to study__ .A.how people dream and learnB.the structure of the nervous systemC.whether someone is reasonableD.the process of understanding2.The purpose of the study attended by 99 college students is to .A.find the hidden tree in the mazeB.test the design of a difficult virtual mazeC.train people’s memoryD.see how dreams and learning are connected3.The better performance in working out the maze is connected with .A.how people dreamB.what people dreamC.when people dreamD.where people dream4.The writer will probably continue to talk about in the 6th paragraph.A.how learning process caused the dreamB.how a dream helps a person learnC.how dreams and learning influence each otherD.how to improve people’s memory

DDBA解析1.D 第一题询问认知学科学家的研究范围，文中第二段有直接提到a cognitive neuroscientist may study the brain processes that help people learn，故选择D2.D 综合推断题。询问文中的研究的目的是什么，由文章中对于参与者做梦和学习技能的能力分析可以得知研究的目的是分析做梦和学习的关系，故选择D3.B 细节题，询问学习成果好坏与人们做梦的关系，文中倒数第二段提到However, people who had other dreams……didn’t show the same improvement，说明学习成果与人们做梦的内容有关，故选择B4.A 由文章最后一段the dream itself doesn’t help a person learn - it’s the other way around得知作者的观点是学习产生梦，所以可推测到他接下来将讨论学习过程是如何导致梦的产生的，故选A
