More and more people are aware that an afternoon nap(小睡) can do a body good. But there are still doubters out there. To help spread the power of the afternoon nap, we list some common misunderstandings about napping we still hear.

Misunderstanding # 1 : Napping is only for the lazy.

Fact: Around a third of American adults nap on the average day, and for good reason: A short nap can improve everything from alertness(警覺) and memory to creativity and productivity(生產效率). And none of these sounds like laziness to us!

Misunderstanding # 2 : If I take a nap, I’ll only wake up feeling worse.

Fact: That weak feeling after you wake up from a nap is real (it even has a name: sleep inertia), but it’s not a guarantee(保證). How you feel after your nap is a factor of how long you sleep. Experts generally agree that a nap should last no longer than 30 minutes. “If it takes longer than 30 minutes, you end up in deep sleep. You’re going into a stage of sleep where you find it very difficult to wake up.” said sleep expert Michael J. Breus, Ph. D. Next time you’re in the mood for a nap, set your alarm for 20 to 30 minutes, tops.

Misunderstanding # 3 : You mustn’t nap at work.

Fact: In fact, in the office environment, we’re all for catching a few winks (眨眼) during the workday. Some companies have even created special rooms for afternoon naps as more and more employers come around to the idea that a well-rested workforce is a more productive workforce. If your employer doesn’t offer a place to lay your head, try to find an empty conference room where you can close the door and turn off the lights. Really want. You can also take a nap during your lunch break on a park bench or in your car.

Misunderstanding # 4 : I’ll be more productive if I just finish this task, rather than waste time sleeping.

Fact: Yes, you’ll be away from your desk if you spend 10 to 30 minutes sleeping. But you’ll likely make up for that “wasted” time afterward. “My research shows that people feel tired after a long time of work during the day,” Sara Mednick told Bloomberg Businessweek. “It’s difficult to keep energetic and productive all day.” However, a nap can leave you feeling refreshed and more ready to deal with the task at hand.

1.According to the passage, a short nap has the following benefits EXCEPT .

A. making people think more quickly

B. improving people’s memory

C. allowing old people to live longer

D. raising people’s work efficiency

2.How you feel after your nap is connected with ________.

A. the way of sleep B. the place of sleep

C. the environment of sleep D. the length of sleep

3.Sara Mednick indicates that _________.

A. taking a short nap at work is a waste of time

B. people become less productive without a nap

C. people become less productive after a nap

D. napping is only for the lazy and young children

4.Which of the following is the best title for the passage?

A. The advantages of taking a nap.

B. The more naps you take, the more productive you become.

C. 4 things people get wrong about napping.

D. How to take an afternoon nap correctly.

Professional footballers have worryingly poor teeth that could be affecting their performance on the football ground, say dentists. Their study on players at eight clubs in England and Wales, in the British Journal of Sports Medicine,showed nearly 4 out of 10 had cavities (蛀牙)and that athletes often had worse teeth than the general population. Regularly taking sugary foods is one possible explanation.

The dentists, from the International Centre for Evidence-Based Oral Health at University College London, examined 187 players’ sets of teeth. They found 53% had dental erosion (腐蝕),45% were bothered by the state of their teeth and 7% said it affected their ability to train or play. Around 40 % had cavities, compared with 30 % of people of a similar age in the general population.

Prof Ian Needleman, one of the researchers, said: “These are individuals who otherwise invest so much in themselves so it,s a surprising finding.

“There are two main groups — some have a catastrophic Professional footballers have worryingly pooreffect, they have very serious disease that stops them in their tracks and they cannot play or train.

“There'11 be others experiencing pain affecting sleep or sensitivity every time they take a drink. ”

At this level of athlete, even small differences can be quite telling.

Nutrition is one of the primary suspects with having too many sugary or acidic foods during training potentially accounting for cavities and erosion. A lot of air in the mouth during exercise can also dry it out so there is less protection.

While these findings are worrying, clubs are attaching greater importance to dental health and educating their players. According to StijinVandenbroucke, head of medicine and sports science at West Ham United, oral health is an area where many athletes have greater problems than the general population and there are clear benefits of oral disease prevention for athletes and clubs.1.What does the passage tell us about professional footballers teeth?

A. Nearly 4 out of 10 players in the UK suffer from toothaches.

B. They have been invested a great deal by individual players.

C. Many players' poor teeth bother their career and daily life.

D. British footballers teeth are examined regularly.

2.What mainly results in professional footballers' poor teeth?

A. Experiencing too much training.

B. Eating food with too much sugar.

C. Breathing in lots of air during exercise.

D. Having little education of oral disease prevention.

3. These findings are worrying clubs because____.

A. footballers aren’t willing to give up sugary or acidic food

B. they've spent much on their players' oral disease prevention

C. footballers have more serious tooth problems than the public

D. players' oral disease may lead to bad performance in games

4.This passage is most probably taken from____.

A. a dentist's diary B. a sports newspaper

C. a medicine magazine D. a science report

LONDON—Manchester is Britain’s fattest city, a survey for “Men’s Health” has found, beating Glasgow for the first time since the magazine started examining the issue three years ago.

Editor Pete Muir said the survey had looked at a variety of factors(因素) from gym membership to heart disease rates to find the fattest city. “Manchester has more fast food restaurants than anywhere else in the UK,” he told Reuters. “People are taking the easy choice —eating and then just sitting in front of the TV.”

Manchester’s problem is part of a wider trend(趨勢). On Thursday, the Office of National Statistics (ONS) blamed(責備) a lack of exercise and poor diet for a fifth of adult Britons being obese(過度肥胖的). “Obesity is a major risky factor related to heart disease, diabetes and premature death(糖尿病和早亡),” said an ONS survey. “None of the 108 young men in the survey reported eating five portions of fruit or vegetables on average each day.”

In Manchester, the head of the city’s public health programs said he did not believe that they were necessarily the fattest city, but that they did have problems and were aiming to address them. Social deprivation(貧困) was a major factor. “One of the myths is that the stressed-out(壓力大的) rich businessman is the one who is overweight,” David Regan told Reuters. “In fact, it is the poor areas that have the most problems. We aim not to be the fattest but the fittest city but we have a long way to go.”

Second in the survey is Stoke-on-Trent, followed by Liverpool, Swansea and Leicester. Glasgow is sixth.

1. Manchester took the place of ____________ and became Britain’s fattest city.

A. Liverpool B. London

C. Stoke-on-Trent D. Glasgow

2.Obesity may lead to the following EXCEPT _______________.

A. heart disease B. diabetes

C. premature death D. a lack of exercise

3.David Regan is most probably _________________.

A. the reporter from Reuters

B. an official of ONS

C. the head of Manchester’s public health programs

D. a rich businessman who is overweight

4. This article is most probably taken from ________________.

A. a newspaper B. a science book

C. a novel D. a biography (傳記)

If you have ever been discouraged because of failure, please read on. Often achieving what you plan to do isn’t the important thing. 1.

Two brothers decided to dig a deep hole behind their house. While they were working, a few older boys stopped by to watch. “What are you doing?” asked one of the visitors. “We plan to dig a hole all the way through the earth!” one of the brothers volunteered excitedly.

The older boys began to laugh, telling the younger ones that digging a hole all the way through the earth was impossible. After a long silence, one of the diggers picked up a jar full of spiders, worms and a wide variety of insects. 2. Then he said quietly and confidently, “Even if we don’t.”

3. And that is what a goal is for –to cause us to move in the direction we have chosen, in other words, to have us digging!

But not every goal will be fully achieved. Not every job will end successfully. Not every relationship will endure. Not every hope will come to pass. Not every love will last. 4.

So when you fail to reach your aim, perhaps you can say, “Yes, but look at what I found along the way! Look at the wonderful things which have come into my life because I tried to do something !” It is in the digging that life is lived. 5.

A. He broke the jar into pieces.

B. He opened the jar and showed the wonderful things contained in it to the laughing visitors.

C. Let me explain.

D. Not every dream will come true.

E. Their goal was far too high, but it did cause them to dig.

F. Here are some reasons for you.

G. And I believe in the end it is joy in the journey that truly matters.
