If you see a student napping (打瞌睡) in the library, don't roll your eyes. New research from the University of California, Berkeley, shows that an hour's nap can considerably improve and restore your brain power. Indeed, the findings suggest that a nap not only refreshes the mind, but can make you smarter.
"Sleep not only rights the wrong of extended wakefulness but it moves you beyond where you were before you took a nap." said Matthew Walker, an assistant professor of psychology at UC Berkeley and the lead investigator of UC Berkeley sleep studies.
The latest study suggests that the brain may need sleep to process short-term memories, creating "space" for new facts to be learned. In their experiment, 39 healthy adults were given a hard learning task in the morning~~with broadly similar results, before half of them were sent for their nap. When the tests were repeated, the nappers improved their scores by 10 percent on average after sleeping; the scores of those who didn't nap actually dropped by 10 percent.
The results support previous data from the same research team that staying up all night―a common practice at college during midterms and finals―decreases the ability to memorize new facts by nearly 40 percent, due to a shutdown of brain regions for lack of sleep, said Walker.
"Sleep is needed to clear the brain's short-term memory storage and make room for new information." said Walker. "It's as though the e-mail inbox in your brain is full and, until you sleep and clear out those e-mails, you're not going to receive any more mail."
However, Professor Derk Jan Dijk, the director of the Surrey Sleep Research Centre, said that there was no clear evidence that daytime napping offered a distinct advantage over sleeping soundly just once over 24 hours.
"The sleep-wake cycle is not as fixed as we might think―we have the capability to sleep in different ways, "said Professor Derk Jan Djjk.
"The size of these effects is much more difficult to judge―if I have to learn something, for example, it's easier to do this when I'm feeling awake and ready than when I'm sleepy." he added.
56.According to UC Berkeley's new findings, the benefit of a nap is that .
A.it helps to fix a napper's sleep-wake cycle
B.it makes hard learning tasks not difficult any more
C.it allows the brain to make room for new learning
D.it gives nappers chances to clear out their memory storage
57.Matthew Walker's study shows that___________.
A.learning ability in the morning is usually higher than that in the afternoon
B.extra working hours before an exam can make up for the lack of daily efforts
C.the size of the effects of napping depends on when it is taken
D.staying up late before an exam does not necessarily improve students' exam performance
58.The two research teams mentioned in the text may both agree that_____________ .
A.people's sleep-wake cycle decides the length of midday nap
B.sufficient sleep betters people's learning performance
C.scientific experiments are undependable as the results are often hard to judge
D.the differences in their findings result from different methods applied
59.What can we learn from this passage?
A.Rolling your eyes can stop you from napping.
B.Some people might move themselves when sleeping.
C.College students tend to study late into night before important exams.
D.Sleeping once over 24 hours is much better than daytime napping.

In bringing up children, every parent watches eagerly the child’s acquisition(学会)of each new skill — the first spoken words, the first independent steps, or the beginning of reading and writing. It is common that parents hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child. This might happen at any stage. A baby might be forced to use a toilet too early, and a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm(热情) for life and his desire to find out new things for himself.
　　Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters; others are severe over time of coming home at night or punctuality(准时) for meals. In general, the controls imposed(强加的) represent the needs of the parents and the values of the community(社区) as much as the child’s own happiness.
　　As regards the development of moral standards （道德标准））in the growing child, consistency（连贯性） is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality. Also, parents should realize that “example is better than precept”. If they are not sincere and do not practise what they preach(说教), their children may grow confused, and emotionally insecure when they grow old enough to think for themselves, and realize they have been to some extent fooled.
　　A sudden awareness of a marked difference between their parents’ principles and their morals can be a dangerous disappointment.
20．Eagerly watching the child’s acquisition of new skills_____.
A．should be avoided
B．is universal among parents
C．sets up dangerous states of worry in the child
D．will make him lose interest in learning new things
21．When children are learning new skills, parents should_____.
A．encourage them to read before they know the meaning of the words they read
B．not expect too much of them
C．achieve a balance between pushing them too hard and leaving them on their own
D．create as many learning opportunities as possible
22．The second paragraph mainly tells us that _____.
A．parents should be strict with their children
B．parental controls satisfy only the needs of the parents and the values of the community
C．parental restrictions vary, and are not always enforced for the benefit of the children alone
D．parents vary in their strictness towards their children according to the situation
23．The underlined word “precept” (in Paragraph 3) probably means “_____”.
A．idea B．punishment C．behavior D．instruction
24．In moral matters, parents should _____.
A．observe the rules themselves
B．be aware of the marked difference between adults and children
C．forbid things which have no foundation in morality
D．satisfy their children’s needs

　　Both warm-blooded and cold-blooded desert animals have ways to escape the desert heat. Warm- blooded desert animals, such as rats and mice, rest during the day, often staying in cool underground burrows. At night they search for food. Animals that are out during the day, such as cold-blooded lizards and snakes, are active only for short periods. As their body temperature rises, these reptiles（爬行动物） move into the shade in order to cool down. In the early evening, when the sun grows weaker, the reptiles become more active and begin their search for food again.
　　Getting enough water to survive is a major problem for all desert animals. Some desert animals, like desert birds, manage to find water holes. Other desert animals, such as the kangaroo rat and the related jerboa, get water only from the food that they eat. Because these animals eat mainly dry seeds, they must survive on a tiny amount of water.
　　Most deserts have only a small number of frogs and toads because these animals must be near water to survive. Yet even these creatures have adapted(适应) to desert conditions. When small amounts of water collect in temporary streams, the desert-living frogs and toads become active. After a rainfall, they lay their eggs. The eggs grow into tadpoles in a few days and into adults in just four weeks. When the puddles(水坑) dry up, the adult frogs or toads dig into the ground. Their metabolism(新陈代谢) slows, and they stay beneath the ground until the next rain, which may be as good as a year away. Until then, their bodily activities continue at a reduced rate.
　　The camel — often called the ship of the desert — is one of the most successful desert animals. Camels can go for long periods without water, but eventually they must drink. When water becomes available to them after a long drought, they may drink 95 liters of water or more. When water is not available, what helps camels survive the desert heat is the fat stored in their humps(驼峰). A camel’s hump contains about 12 kilograms of fat. Fat is rich in hydrogen. As the fat is digested, hydrogen from the fat combines with oxygen in the air that the camel breathes. The result is H2O, or water. Each kilogram of fat that a camel digests produces about a liter of water.
16．Desert animals are usually more active at night because _____.
A．it is cooler at night B．it is easier to find water
C．they like the dark D．they are less likely to be attacked at night
17．Which of the following desert animals can get water only from the food?
A．The camel. B．The kangaroo. C．The frog. D．The rat.
18．Which of the following is TRUE according to the passage?
A．All the desert animals rest during the day.
B．All the desert animals don’t rest during the day.
C．Cold-blooded desert animals are out most of the day.
D．None of the cold-blooded desert animals go out during the day.
19．The underlined word “burrows” in the first paragraph can be replaced by _____.
A．holes B．caves C．rooms D．openings

二、阅读理解
阅读下列短文，从每题所给的A、B、C和D项中，选出最佳选项，并在答题卡上将该项涂黑。
Not many years ago, a wealthy and rather strange old man named Johnson lived alone in a village in the south of England. He had made a lot of money in trading with foreign countries. When he was 75, he gave £12,000 to the village school to buy land and equipment for a children’s playground.
As a result of his kindness, many people came to visit him. Among them was a newspaperman. During their talk, Johnson remarked that he was 75 and expected to live to be 100, and the newspaperman asked him how he managed to be healthy at 75. Johnson had a sense of humor. He liked whisky and drank some each day. “I have an injection(注射)in my neck each evening”, he told the newspaperman, thinking of his evening glass of whisky.
The newspaperman did not understand what Johnson meant. In his newspaper he reported that Johnson was 75 and had a daily injection in his neck. Within a week Johnson received thousands of letters from all over Britain, asking him for the secret of his daily injection.

Heavy downpours last month in Rhode Island led to widespread flooding, causing millions of dollars in property damage and leaving thousands homeless. The flood waters also poured vast amounts of raw sewage(未经净化的污水) into the rivers and streams that flow into Narragansett Bay.
It sounds like the makings of an environmental nightmare. But in fact it’s just the opposite. To scientists’ delight. The sewage-loaded floodwaters have caused a well-timed growth of phytoplankton. The microscopic creatures that form the foundation of marine(海洋的) food chains. With more food available for fish. Clams and other sea creatures. The bay’s fisheries industry is expected to benefit.
In decades past. Narragansett Bay typically experienced a late winter early spring algal(海藻) bloom that fed creatures up and down the water column. But in recent years, the waters of Narragansen Bay warmed greatly, meriting this seasonal event.
Mark Berman, an oceanographer with the Nationa. Marine Fishertes Service. Said the flood seemed to have sent the bay back in its normal state.
However, local, mutate and federal officials in Rhode Island leave been batting other algal blooms that, by contrast, are causing widespread harm to the Narragansett Bay ecosystem. During summer months, sewage and agricultural runnel flows into the bay. Causing large blooms. But inseam of becoming food for sea creatures, much of the phytoplankton is consumed by bacteria, which grow last in the warmer waters. The rapid bacteria growth leads to hypoxia decrease of oxygen in the water that can cause large fish tools. One such die-off occurred in 2003. when millions of oxygen-starved fish washed up on the belches of Narragansett Bay.
The flood’s positive impact will probably be a one-time event, Mr Berman said. Mcanwhile efforts to curb the harmhl summer honors continue; in 2003. for instance, Providence completed a $359 million sewage tonal under the city designated to reduce the polluted storm overflow into Narragansett Bay.
71．Scientists believe that the row sewage flowing into the bay will .
A．pollute the island’s environ mean B．cause lots of property damage
C．increase the fisheries production D．destroy the food chains in the bay
72．The potential benefit of fisherics industry rclics on the .
A．warm temperatures of the bay. B．growth of phytoplankton
C．large summer alga blooms D．consumption of oxygen by beaters
73．People struggle against the summer blooms because they will .
A．pollute the local natural environment
B．increase the prcducmon of fishery industry
C．cause large fish kills of the bay indirectly
D．provide too much food ior sea creatures
74．It can be inferred that .
A．money spent on the summer blooms has been wasted
B．the government is inverting to promote the local fisheries
C．research of accanology should he encouraged
D．she raw sewage impacts are currently con radiator
75．The underlined word “carb” n the hast postage can be defined as “ ”.
A．control B．consume C．cause D．cure

A．waiting for its other food	B．enjoying its food- katydid
C．eating a leaf from the branch	D．having a break under the tree

A．is a kind of meat-eafer	B．is easy to be found by a katydid
C．looks more like a green leaf	D．mainly lives on the green leaves
