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, and 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.”

68. We can learn from the article that ________.

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

69. The underlined word “subjects” in paragraph 3 probably mean________.

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

70. The text is most probably taken from ________.

A. a newspaper report           B. a library guide

C. a project handbook           D. a science site

Are you sometimes a little tired and sleepy in the early afternoon? Many people feel this way after lunch. They may think that eating lunch is the cause of the sleepiness. Or, in summer, they may think it is the heat. However, the real reason lies inside their bodies. At that time – about eight hours after you wake up – your body temperature goes down. This is what makes you slow down and feel sleepy. Scientists have tested sleep habits in experiments where there was no night or day. The people in these experiments almost always followed a similar sleeping pattern (模式). They slept for one long period and then for one short period about eight hours later.

In many parts of the world, people take naps(小睡) in the middle of the day. This is especially true in warmer climates, where the heat makes work difficult in the early afternoon. Researchers are now saying that naps are good for everyone in any climate. A daily nap gives one a more rested body and mind and therefore is good for health in general. In countries where naps are traditional, people often suffer less from problems such as heart disease.

Many working people, unfortunately, have no time to take naps. Though doctors may advise taking naps, employers do not allow it! If you do have the chance, however, here are a few tips about making the most of your nap. Remember that the best time to take a nap is about eight hours after you get up. A short sleep too late in the day may only make you feel more tired and sleepy afterward. This can also happen if you sleep for too long. If you do not have enough time, try a short nap – even ten minutes of sleep can be helpful.

1. Why do people feel sleepy in the early afternoon according to the text?

A.They eat too much for lunch.

B.They sleep too little at night.

C.Their body temperature becomes lower.

D.The weather becomes a lot warmer.

2.If you get up at 6:30 am, what is the best time for you to take a nap?

A.About 12:30 pm.                        B.About 1:30 pm.

C.About 3:30 pm                         D.About 2:30 pm

3. What would be the best title for the text?

A.Just for a Rest

B.All for a Nap

C.A Special Sleep Pattern.

D.Taking Naps in Warmer Climate.

下面文章中有5处需要添加小标题。请从以下选项(A、B、C、D、E和F)中选出符合各段意思的小标题,并在答题纸上将相应选项的标号涂黑。选项中有一项是多余选项。

A. Early to Bed, Early to Rise

B. Read Challenging Books

C. Exercise

D. Relax yourself

E. Minimize Television Watching

F. Take Time to Reflect

Five Simple Ways to Increase Your Intelligence

Your brain needs exercise just like a muscle. If you use it often and in the right ways, you will become a more skilled thinker and increase your ability to focus.

Here are 5 simple ways anyone can squeeze a bit more productivity out of the old gray matter.

1._______– This is a hard sell. People love vegetating in front of the television, myself included more often than I’d like. The problem is watching television doesn’t use your mental capacity OR allow it to recharge. It’s like having the energy sapped out of a muscle without the health benefits of exercise.

When you feel like relaxing, try reading a book instead. If you’re too tired, listen to some music. When you’re with your friends or family, leave the tube off and have a conversation. All of these things use your mind more than television and allow you to relax.

2._______ – I used to think that I’d learn more by not exercising and using the time to read a book instead. But I realized that time spent exercising always leads to greater learning because it improves productivity during the time afterwards. Using your body clears your head and creates a wave of energy. Afterwards, you feel invigorated and can concentrate more easily.

3._______– Many people like to read popular suspense fiction, but generally these books aren’t mentally stimulating. If you want to improve your thinking and writing ability you should read books that make you focus. Reading a classic novel can change your view of the world and will make you think in more precise, elegant English. Don’t be afraid to look up a word if you don’t know it, and don’t be afraid of dense passages. Take your time, re-read when necessary, and you’ll soon grow accustomed to the author’s style.

4.________– Nothing makes it harder to concentrate than sleep deprivation. You’ll be most rejuvenated if you go to bed early and don’t sleep more than 8 hours. If you stay up late and compensate by sleeping late, you’ll wake up lethargic(无精打采) and have trouble focusing. In my experience the early morning hours are the most tranquil and productive. Waking up early gives you more productive hours and maximizes your mental acuity(敏锐) all day.

If you have the opportunity, take 10-20 minute naps when you are hit with a wave of drowsiness. Anything longer will make you lethargic, but a short nap will refresh you.

5.________ – Often our lives get so hectic that we become overwhelmed without even realizing it. It becomes difficult to concentrate because nagging thoughts keep interrupting. Spending some time alone in reflection gives you a chance to organize your thoughts and prioritize your responsibilities. Afterwards, you’ll have a better understanding of what’s important and what isn’t. The unimportant stuff won’t bother you anymore and your mind will feel less encumbered.

Conclusion – I hope you aren’t disappointed that none of the techniques I’ve proposed are revolutionary. But simple, unexciting answers are often the most valid. The challenge is having the will to adhere to them. If you succeed in following these 5 tips, you’ll be rewarded with increased mental acuity and retention of knowledge.
