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. 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(气候), 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 (传统的), people often suffer less from problem 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.
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.

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

l like to feel close to someone. It is nice to have a friend to talk, laugh and do things with. Surely, there are times when we need to be alone. We don't always want people around. But we would feel lonely if we never had a friend.
No two people are the same. Sometimes friends don't get along well, which doesn't mean that they no longer like each other. Most of the time they will go on being friends. Sometimes friends move away, then we feel very sad. We miss them much, but we can call them and write to them. Maybe we would never see them again, and we can make new friends. It is surprising to find out how much we like new people when we get to know them. Families sometimes name their children after a close friend. Many places are named after men and women, if they are friendly to people in a town. So are some schools. We think of these people when we go to these places.
There's more good news for people, if they have friends. These people live longer than those people if those don't have friends. Why? It could be that they are happier. Being happy helps you stay well. Or it could be just knowing that someone cares, if someone cares about you, you take better care of yourself.

While success is surely sweeter than failure, it seems failure is a far better teacher, and organizations that fail spectacularly often flourish more in the long run, according to a new study by Vinit Desai, assistant professor of management at the University of Colorado Denver Business School. Researchers have found that people missing their goals perform much better in the long run. That is because they gain more knowledge from their failures than their successes and the lessons are more likely to stay longer in their minds.
“We found that the knowledge gained from success was often fleeting while knowledge from failure stuck around for years,” said professor Desai, who led the study. “But companies often ignore failure. Managers may fire people or turn over the whole workforce while they should treat the failure as a learning opportunity.”
Prof Desai compared the flights of the space shuttle Atlantis and the Challenger. During the 2002 Atlantis flight, a piece of insulation (绝缘体) broke off and damaged the left solid rocket booster (助推火箭) but didn’t influence the program. There was little investigation. The Challenger was launched next and another piece of insulation broke off. This time the shuttle and its seven–person crew were destroyed. The disaster led to a major investigation resulting in 29 changes to prevent future disasters.
The difference in response in the two cases came down to this: Atlantis was considered a success and the Challenger a failure.
“Despite crowded skies, airlines are extremely reliable,” he said. “The number of failures is extremely small. And past researches have shown that older airlines, those with more experience in failure, have a lower number of accidents.”
Prof Desai doesn’t recommend finding out failure in order to learn. Instead, he advises organizations to analyze small failures to collect useful information rather than wait for major failures.
Why did experts pay little attention to the problem of Atlantis?

A.Because it worked perfectly.
B.Because the right booster was still OK.
C.Because nothing serious happened then.
D.Because fewer people died in the flight.

Fewer accidents happen to older airlines in that _____.

A.their planes couldn’t fly high in the sky
B.they gained much from experience in failure
C.their planes were often checked by the experts
D.they were unpopular among passengers

The passage is written mainly to _____.

A.show failure is a better teacher than success
B.explain why Challenger failed
C.introduce something about Prof Desai
D.tell managers how to achieve success

Which writing strategy is NOT used in developing the passage?

A.Giving definitions. B.Making comparisons.
C.Analyzing causes. D.Providing different examples.

When many people see birds cleaning their feathers, they attribute it to vanity on the part of the bird. But, in reality, what they are doing is maintaining their wings, the instruments that they depend on for safe flight. If a bird’s wings are not in perfect condition, the bird either won’t be able to fly or won’t be able to control its flight. That is why after a long flight and even throughout the day, you will see them cleaning their feathers.
Most birds, if they get a chance, will take a bath at least once a day. They do this to get rid of the dust that has accumulated in their feathers throughout their flight s during the day. In dry or desert areas, birds will not always be able to find water in which to bath, but they still need to clean their feathers. What many birds will do is to take dust baths. They will roll around in dust until it covers their feathers. They will stand up, shaking the dust out, and then clean their feathers with their beaks (鸟嘴) as usual.
Baths are important for another reason. During the course of the day and night, many parasites (寄生虫) are attracted to birds. Bugs, mites, fleas and so on will try to reach birds and suck from their blood. Daily baths help to keep the parasites to a minimum.
Some birds, especially those that spend a lot of time in or around water, have skin glands (皮肤腺) that produce oil. After bathing, these birds will squeeze the glands to spread the oil over their wings to keep them free of water.
If you are a bird lover and have bird houses in your yard, it can be good to go to the extra step, providing a bird bath. Once the birds in your neighborhood discover it, you will be surprised at how popular it becomes as they periodically stop by to take their daily bath.
What’s the passage mainly about?

A.How birds clean themselves. B.What birds enjoy doing.
C.Why baths matter so much to birds. D.What bird lovers should do.

What does the underlined part in Para 1 probably mean?

A.Most people think it good for birds to clean their feathers.
B.Most people show much interest in how birds clean themselves.
C.Most people believe that birds’ keeping themselves clean is necessary.
D.Most people think birds’ cleaning their feathers of no practical significance.

According to Para 3, birds’ feather cleaning _____.

A.helps keep them healthy B.keeps them free of any parasite
C.makes them more attractive D.helps them relax enough

In the last paragraph, the author further reminds us that _____ .

A.we should love birds as much as possible
B.birds enjoy cleaning themselves by bathing
C.we can be good bird lovers by bathing birds
D.birds like to come close to the people in a yard
