Question

5．People who enjoy a dream-filled sleep are better at recalling information and making links between facts when waking．But recharging with a shallow （小睡） offers no such mental improvement，the research suggests．The results of the study added to the growing body of evidence that Rapid Eye Movement （REM） sleep is very important to the brain's ability to form strong memories．
An average night's rest includes four or five spells of REM sleep，but these bursts tend to be lengthier towards the end of the night．This means adults getting less than the recommended seven to eight hours a night--and therefore inadequate REM sleep--may be damaging their mind's ability to memorize：Although REM sleep is not classified as a type of deep sleep，it is only reached after the brain has passed through deep sleep stages．
In the recent study，participants were shown groups of three words and asked to find another word that can be associated with all three words．They were tested once in the morning and then given the same task again in the afternoon．In between，some were allowed a nap with REM sleep，some a nap without REM sleep，while the others had a quiet rest period．The quiet rest and non-REM sleep groups didn't improve，but the REM sleep group improved on their morning performance by an average of almost 40 per cent．Dr Sara Mednick，a sleep researcher at the University of California who led the study，believes the formation of connections between previously unassociated information in the brain occurs during REM sleep．
It is believed that sleep acts as a sort of mental filing system，enabling the brain to sort relevant information from useless information．This process may take place as memories are removed hem one art of the brain to others．

Answer 1

分析 研究表明，喜欢睡觉做梦的人在醒着的时候更善于回忆信息和事实之间的联系．但是小睡没有提供这样的心理改善，越来越多的证据表明，快速眼动（REM）睡眠对大脑形成强烈记忆的能力非常重要．

解答 76．Benefits/Improves 词义归纳题．根据第一段的Peoplewho enjoy a dream-filled sleep are better at recalling information and makinglinks between facts when waking．可知REM可以提高记忆力，故填Benefits/Improves．
77．strengthen 词形转化题．根据第一段的句子：Theresults of the study added to the growing body of evidence that Rapid EyeMovement （REM） sleep is very important to the brain's ability to form strong memories．可知REM可以增强记忆力，填strengthen．
78．process/steps/procedures归纳题．右边的内容是研究的过程，故填process/steps/procedures．  
79．Participants 原词重现．根据第三段的In the recent study，participantswere shown groups of three words and asked to find another word that can beassociated with all three words．可知答案是Participants．
80．twice 词义归纳题．根据第三段的Theywere tested once in the morning and then given the same task again in theafternoon．可知一天给参与者两次任务，故填twice．
81．improvement 词形转化题．根据第三段的Thequiet rest and non-REM sleep groups didn"t improve，可知将improve改成improvement．    
82．performed词形转化题．根据第三段的but theREM sleep group improved on their morning performance by an average of almost40 per cent．可知将performance 改成performed．
83．opinion/view/belief 归纳词．右边的内容是Dr SaraMednick的观点，故填opinion/view/belief．
84．formed 词形转化题．根据第三段的believesthe formation of connections between previously unassociated information in thebrain occurs during REM sleep．可知 formation改成formed．
85．relevant/related 原词重现．根据第四段的It is believed that sleepacts as a sort of mental filing system，enabling the brain to sort relevant information fromuseless information．可知填relevant/related．
