Lead researcher Bob Stickgold at the Harvard Medical School said, "Sleep helps us draw rules from our experiences. It's like knowing the difference between dogs and cats. even if it's hard to explain. "
The US research team studied how well students remembered connections between words and symbols (象征) , reports New Scientist. They compared how the students performed if they had had a sleep between seeing the words and having the test, and if they had not slept. They found that people were better able to remember lists of related words after a night' s sleep than after the same time spent awake during the day. They also found it easier to remember themes (主题) that the words had in common. But they forgot around one in four more themes if they had been awake. Prof. John Groeger, of Surrey University's Sleep Research Centre, said, "People have been trying for years to fard out what the purpose of sleep is, as we know that only certain parts of it have a restorative (有助恢复的) value. "
" We form. and store huge numbers of experiences in the head every day, and sleep seems to be the way the brain deals with it all. "
The phrase" to sleep on a problem" in Paragraph 1 most likely means to______.
A．pay full attention to a problem
B．wait until later for a decision
C．sleep to forget a problem
D．have difficulty sleeping

To limit sleep means our health and daytime potential are significantly reduced. So, good sleep strategies are essential in order to feel energized day after day. There is no strategy which works for everyone, so each person needs to experiment. One important thing is that you shouldn't worry too much if you go a few nights without a lot of sleep. It won't ruin your life. On any given night, one in four people can't sleep properly and everyone suffers from a lack of sleep at some time.
How does one minimize this problem？ It is really quite simple. The first thing you must do is to reduce stress as much as possible. Stress is part of everyday life and, while we can never be entirely without stress, it can be managed. This means taking control of your life and focusing on what is important. One sleeping strategy is to sit in a comfortable position, close your eyes and relax all your muscles, breathing easily through your nose. Continue this for ten to twenty minutes. This should help you reduce stress and sleep better. Or, you can try getting plenty of exercise, because a tired body is likely to sleep better.
According to the article, sleep is important because______.
A．it is a period of complete inactivity for the brain
B．it helps us understand what we have already achieved
C．it makes us more effective when we are awake
D．it helps us to lose weight

Recent studies have shown that the parts of the brain that we use to learn a task become active again during sleep. This activity, scientists suggest, could be the brain transferring memories from short-term to long-term storage.
But the brain doesn't necessarily wait until the lights are out to begin processing those memories.
To find out how the brain handles memories during waking hours, scientists gave 15 volunteers two tasks, each requiring different parts of the brain to learn. In one task, the subjects learned how to navigate a virtual town and then searched the town for an object. In the second task, they learned to predict where a sequence of dots would appear on a screen.
Using a special machine, the researchers scanned the volunteers' brains right before and right after the tasks. They compared the two images to see whether the regions of the brain involved in learning the task were still active even after the task was completed.
After a break, the scientists took a third image of each participant's brain. They wanted to determine whether these regions in the brain continued to be active after snore time had passed.
They discovered that, for at least an hour after learning a task, the brain stays active. It appears to continue processing the new information.
Furthermore, the images showed that distracting the subjects doesn't affect their ability to store memories. The processing continues even when they're thinking about or doing other things.
Some scientists say this could mean that sleep isn't essential for storing memories. Others disagree. Until that's settled, it's probably still better to be on the safe side, getting plenty of sleep.
According to the passage, ______.
A．a good night's sleep helps your brain permanently file away lessons learned during the day.
B．the brain has to wait until the lights are out to begin processing those memories
C．perhaps it's safe for anyone to get plenty of sleep when it has not been proved unnecessary for memory
D．attracting the subjects doesn't affect their ability to store memories.
