单选题
According to a new research, dreaming about
something you've learned may actually be an indicator that your memory is
working overtime to retain that information. Doctors have long {{U}}
{{U}} 21 {{/U}} {{/U}}the importance of a good night's rest-for
everything from improving performance to {{U}} {{U}} 22 {{/U}}
{{/U}}physical well being. {{U}} {{U}} 23 {{/U}} {{/U}}this latest
inquiry suggests that {{U}} {{U}} 24 {{/U}} {{/U}}sleep is
beneficial, dreams may actually {{U}} {{U}} 25 {{/U}}
{{/U}}whether our memories continue to work through {{U}} {{U}} 26
{{/U}} {{/U}}. In this latest research, researchers found that, after
{{U}} {{U}} 27 {{/U}} {{/U}}performing a task, study
participants who took a nap and dreamt about that task {{U}} {{U}}
28 {{/U}} {{/U}}both those who hadn't slept, and those who'd had a
dreamless sleep or whose dreams didn't touch {{U}} {{U}} 29
{{/U}} {{/U}}the task. As part of the research, subjects were
asked to study a three dimensional computer maze so that later, when they were
{{U}} {{U}} 30 {{/U}} {{/U}}placed somewhere in the middle of
that maze, they'd be able to find their way out. Between the initial {{U}}
{{U}} 31 {{/U}} {{/U}}of the maze, and the later task, some
participants were allowed to nap. Among those who rested, several had dreams
that {{U}} {{U}} 32 {{/U}} {{/U}}the maze-some saying that their
dreams {{U}} {{U}} 33 {{/U}} {{/U}}the music that had been
playing while they studied the maze earlier, while others imagined the maze as
{{U}} {{U}} 34 {{/U}} {{/U}}caves that they'd had to {{U}}
{{U}} 35 {{/U}} {{/U}}through. Later, when participants were put
back in the maze, those who'd dreamt about it had greater {{U}} {{U}}
36 {{/U}} {{/U}}finding their way around than those who hadn't dreamt
about the {{U}} {{U}} 37 {{/U}} {{/U}}, or who hadn't slept at
all. The findings indicate that dreams may be a(n) {{U}}
{{U}} 38 {{/U}} {{/U}}of memory processing, and working over a
problem in your sleep is a(n){{U}} {{U}} 39 {{/U}} {{/U}}that
your brain is actively trying to {{U}} {{U}} 40 {{/U}}

dreams during a full night's sleep relate to memory process.
【答案解析】语义逻辑题，考查词义辨析。填入的形容词修饰其后的physical well being，这里指“身体健康方面”，overall意为“整体的，总的，从头到尾的”，此处修饰physical well being合适，选C项。
A项意思和C项有些相似，干扰性较大。但是，A项和C项在用法上有区别：若要表示“整体的”意义，应该用C项；若要表示“全部的，整个的”，用A项。且entire只能用在名称前，如：The entire country was affected by drought．全国都受到干旱影响。
【答案解析】语义逻辑题。performing a task意为“执行任务”，dreamt a task意为“梦到任务”，题目考查在任务执行的某一时间段让人们休息，第二段对该实验进行的过程作如下介绍：Between the initial viewing of the maze，and the later task，some participants were allowed to nap，由此可见，是在任务刚开始执行后让人们小睡休息的，故选A项。
单选题
A. overcame
B. lost
C. ruined
D. outperformed
【正确答案】
D
【答案解析】语义逻辑题，考查词义辨析。解答此题可以联系第二段后半部分表明的实验结果，其中greater…than等词表明，小睡梦到任务内容的人要比没有小睡或小睡没有梦到任务内容的人表现更好，这里用outperfomed符合句意。
A项具有一定的干扰，意为“战胜，克服，征服”，如：overcome the enemy打败敌人；overcome a fault克服缺点。此处并不是一场战斗，也与克服困难、缺点无关，因此不符合题意。
