Question

1．Naps-short sleeps during the day-may improve memory，experts said recently．
New research conducted by brain researcher Avi Karni of the University of Haifa in Israel explores the possibility that naps help lock in sometimes long-term memories．"We still don't know exactly how memory system works during sleep，but the results of this research suggest it is possible to speed up memory consolidation（巩固），"Karni said．Long-term memory refers  to memories that stay with us for years，such as"what"memories--a car accident that happened yesterday--or"how to"memories，such as one's learned ability to play the pianos．
Karni，also one of the authors of the study published in a recent issue of the journal Nature Neuroscience，instructed participants to learn a difficult set of finger games，then divided the study subjects into two groups：one that napped for an hour，and one that didn't．The people who took an afternoon snooze showed obvious improvement in their performance by that evening．
"After a night's sleep the two groups were at the same level，but the group that slept in the afternoon improved much faster than the group that stayed awake，"Karni said．And the study also showed just how much faster a 90-minute nap could help lock in long-term memories．"Daytime sleep can shorten the time‘how to'memory weakens and forgetting starts，"Karni said，"Instead of 6 to 8 hours，the brain consolidated the memory during the 90-minute nap．"
64．We can learn from the article thatC．
A．the new research has discovered the memory process during the sleep
B．taking a nap helps improve both long-term and short-term memories
C．Karni's findings are based on comparisons between two groups of participants
D．people who take a nap will never forget"how to"skills once they are learned
65．The underlined word"subjects"in paragraph 3 probably meanA．
A．the people being tested in the study
B．the people carrying out the study
C．the topics being discussed in the study
D．the areas of knowledge being studied
66．The text is most probably taken fromD
A．a newspaper report     B．a library guide
C．a project handbook     D．a science site．

Answer 1

分析 本文是一篇科教类阅读，专家最近说，白天小睡一会会提高记忆力，本文以此展开谈论，主要讲述了一项关于在白天小睡一会可以提高记忆力的一项研究发现，以及研究所进行的实验过程．

解答 64．答案：C．细节理解题．根据"instructed participants to learn a difficult set of finger games，then divided the study subjects into two groups：one that napped for an hour，and one that didn't"可知，卡尼的发现是基于对比两组的参与者．故选C．
65．答案：A．词义猜测题．根据下文"The people who took an afternoon snooze showed obvious improvement in their performance by that evening．"可知，此处subjects样本指的是研究中测试的人．故选A．
66．答案：D．推理判断题．根据文章内容可知，本文是一篇科普类文章，应该来源于一个科学网站．故选D．

点评 本文是一篇科教类阅读，题目涉及多道细节理解题．词义猜测题，推理判断题．做题时学生应仔细阅读原文，把握文章主要内容，联系文章上下文内容并结合所给选项含义，从中选出正确答案，一定要做到有理有据，切忌胡乱猜测．
