It is often said that the best way to get to the bottom of a hard problem is to sleep on it. Does this make sense? A new study shows that it does.

A team of researchers at Northwestern University, US, found that sleeping is useful in both strengthening(增强) and reorganizing(重组)memory. 1.

The researchers did an experiment on 57 university students. They asked students to solve 42 difficult puzzles (谜题) on the first day.2. The researchers encouraged students to remember the music they heard while solving the puzzles. By the end, there were six puzzles that the students still hadn't solved.

3. They were given special sleep-monitoring(睡眠监测)and music devices(设备). The devices played music linked with the unsolved puzzles while the students were in the slow-wave(慢波) sleep stage (阶段). This stage is when people are likely to dream and reorganize their memories.

The next morning, the students tried the unsolved puzzles again.4. The music activated(激活） the memories they had of the puzzles while they were sleeping. It allowed them to "work” on the puzzles in their sleep.

Former studies of both people and animals have shown that sleep can not only strengthen memory, but also help us organize and send information.5. So the next time you face a difficult problem, sleep on it. Play some music to remind yourself of the problem.

A.Researchers found they were 55 percent more likely to solve them.

B.This can help you solve problems.

C.This study is more evidence(证据)of these findings.

D.The students then went back home to sleep.

E.Students worked on each puzzle while listening to different music.

【解析】

本文介绍了美国西北大学的一个实验：睡眠在增强（或重组）记忆方面都很有用。他们让学生未解的谜题留到明天，经过一夜的睡眠和和睡眠中听未解之谜的音乐，第二天他们很容易解出谜题。故睡眠不仅能增强记忆，还能帮助我们组织和发送信息。因此，下次你遇到难题时，就好好睡一觉。同时，播放一些音乐来提醒自己这个问题。

1.句意：这能帮你解决问题。

根据上文“It is often said that the best way to get to the bottom of a hard problem is to sleep on it.

根据下文“The researchers encouraged students to remember the music they heard while solving the puzzles.（研究人员鼓励学生在解谜时记住他们听到的音乐。）”可知此句是“学生们一边听不同的音乐一边做每一个谜题。”故选E。

3.句意：然后学生们回家睡觉。

根据下文“他们得到了特殊的睡眠监测和音乐设备。当学生处于慢波睡眠阶段时，这些设备播放与未解决的智力游戏相关的音乐。这个阶段是人们有可能做梦和重组记忆的时候。”可知此句是“然后学生们回家睡觉。”故选D。

4.句意：研究人员发现，他们解谜的可能性要高出55%。

根据上文“The next morning, the students tried the unsolved puzzles again.（第二天早上，学生们又试了一次未解决的谜题。）”可知此句是“研究人员发现，他们解谜的可能性要高出55%。”。故选A。

5.句意：这项研究是这些发现的更多证据。

根据上文“Former studies of both people and animals have shown that sleep can not only strengthen memory, but also help us organize and send information.（以前对人和动物的研究都表明，睡眠不仅能增强记忆，还能帮助我们组织和发送信息。）”可知此句是“这项研究是这些发现的更多证据。”故选C。
