试题详情及答案解析

Napping(小睡) after learning something new could help improve your memory…as long as you dream, scientists say.
They found people who dream about a new task do it better on waking than those who do not sleep or do not dream.
Volunteers were asked to learn the layout(设计) of a 3D computer maze(迷宫) so they could find their way several hours later. Those allowed to take a nap and who also remembered dreaming of the task, found their way to a landmark (地标) quicker.
The researchers think the dreams are a sign that unconscious(无意识的) parts of the brain are working hard to process information about the task.
Dr. Robert Stickgold of Harvard Medical School, said dreams may be a marker that the brain is working on the same problem at many levels.
Study tips
Co-author Dr. Erin Wamsley said the study suggests our non-conscious brain works on the things that it deem (认为) are the most important.
"Every day we are gathering lots of information and new experiences," she said. "It would seem that our dreams are asking the question, "How do I use this information to inform(影响) my life?"
The scientists say there may be ways to use this phenomenon(现象)for improving learning and memory. For example, students might be better studying hard before bedtime, or taking a nap after a period of afternoon study.

试题分析：科学家称，在学了一些新东西之后小睡一会儿能够帮助大脑记忆-只要你做了梦。他们发现一些做梦梦到一项新任务的人醒来之后会很好地完成这项任务，而且比那些不睡觉或不做梦的人完成地要好一些。研究者们发现，做梦是大脑的下意识部分正在认真处理有关这项任务的信息的信号。有很多方法可以利用这种现象，来提高学习能力和记忆力。例如，学生在睡前努力学习，或者一段时间的午间学习之后睡一会，学习效果会更佳。
