（英语类学生必做）

Sleep is important to us because it helps restore organs and tissues in our body. But how much sleep do we actually need？

For most of us, eight hours seems to be about the right amount. Yet we know that there are many people who get 【61】 perfectly with less sleep, and some who may need 【62】 A great deal depends on the 【63】 we live. But a good general rule 【64】 is to sleep as long as we have to in order to feel happy and be able to work 【65】 our best when we awaken.

There are actually different 【66】 of sleep. There is a deep sleep and a shallow sleep. In a shallow sleep our body does not get the same kind of rest it gets in a 【67】 sleep, 【68】 after eight hours of a shallow sleep we may still feel tired. But a short, deep sleep can be very 【69】 Alexander—the Great Emperor was able to get a deep sleep 【70】 he needed it. Once, during the night before an important battle, he remained 【71】 longer than anyone else. 【72】 he wrapped himself in a cloak and 【73】 down on the earth. He slept so 【74】 that his generals had to wake him three times for him to give the 【75】 to attack!

Normally when we go to sleep, our " sleep center" blocks off nerves so that 【76】 our brain and body go to sleep. 【77】 prevents us from wanting to do anything, and the other 【78】 our internal organs and limbs go to sleep. 【79】 sometimes only one goes to sleep and the other does not. A very tired soldier can sometimes 【80】 asleep (brain sleep) and keep on marching, because his body is not asleep.

Material culture refers to the touchable, material "things"—physical objects that can be s

een, held, fell, used — that a culture produces. Examining a culture's tools and technology can tell us about the group's history and way of life. Similarly, research into the material culture of music: can help us to understand the music culture. The most vivid body of "things" in it, of course, are musical instruments. We cannot bear for ourselves the actual sound of any musical performance before the 1870s when phonograph was invented, so we rely on instruments for important information about music-cultures in the remote past and their develop ment. Here we have two kinds of evidence: instruments well preserved and instruments pictured in art. Through the study of instruments, as well as paintings, written documents, and so on, we can explore the movement of music from the Near East to China over a thousand years ago, or we can outline the spread of Near Eastern influence to Europe that resulted in the development of most of the instruments in the symphony orchestra.

Sheet music or printed music, too, is material culture. Scholars once defined folk music-cultures as those in which people learn and sing music by ear rather than from print, but research shows mutusl influence

among oral and written sources during the past few centuries in Europe, Britain, and America. Printed versions limit variety because they tend to standardize any song, yet they stimulate people to create new and different songs. Besides, the ability to read music notation has a far-reaching effect on musicians and, when it becomes widespread, on the music cul Lure as a whole.

One more important part of music's material culture should be singled out: the influence of the electronic media—radio, record player, tape recorder, television, and videocassette, with the future promising talking and singing computers and other developments. This is all part of the "information revolution", a twentieth-century phenomenon as important as the industrial revolution was in the nineteenth. These electronic media are not just limited to modern nations; the)' have affected music cultures all over the globe.

Research into the material culture of a nation is of great importance bucause ______.

A．it helps produce new cultural tools and technology

B．it can reflect the development of the nation

C．it helps understand the nation's past and present

D．it can demonstrate the nations civilization

When we see well, we do not think about our eyes very often. It is only when we cannot see

perfectly that we realize how important our eyes are.

People who are near-sighted can only see things that are very close to their eyes.' Everything else is not so clear. Many people who do a lot of close work, such as writing, reading and sewing, become near sighted. Then they have to wear glasses in order to see distant (远处的) things clearly.

People who are far-sighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm's length. If they want to do much reading, they must get glasses, too.

Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people's eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them."

Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle (角度). To prove this to yourself, look at an object out of one eye; then look at the same object out of the other eye. You will find the object's relation to the background (背景) and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.

We should take good care of our eyes ______.

A．only when we cannot see perfectly

B．only when we can see well

C．even if we can see well

D．only when we realize how important our eyes are

根据材料，回答下列各题： Why Teenagers Really Do Need an Extra Hour in Bed？ A) "Making tee

ns start school in the morning is cruel ," brain doctor claims. So declared a British newspaper headline in 2007 after a talk I gave at an academic conference. One disbelieving reader responded: " This man sounds brain-dead. " B) That was a typical reaction to work I was reporting at the time on teenage sleep patterns and their effect on performance at school. Six years on there is growing acceptance that the structure of the academic day needs to take account of adolescent sleep patterns. The latest school to adopt a later start time is the UCL Academy in London; others are considering following suit. C) So what are the facts about teenage sleep, and how should society adjust to these needs？ The biology of human sleep timing, like that of other mammals, changes as we age. This has been shown in many studies. As adolescence begins, bedtimes and waking times get later. This trend continues until 19.5 years in women and 21 in men. Then it reverses. At 55 we wake at about the time we woke prior to adolescence. On average this is two hours earlier than adolescents. This means that for a teenager, a 7 a.m. alarm call is the equivalent of a 5 a.m. start for a person in their 50s. D) Precisely why this is so is unclear but the shifts related with changes in hormones (荷尔蒙) at adolescence and the decline in those hormones as we age. However, biology is only part of the problem. Additional factors include a more relaxed attitude to bedtimes by parents, a general disregard for the importance of sleep, and access to TVs, DVDs, PCs, gaming devices, cell phones and so on, all of which promote alertness and eat into time available for sleep. E) The amoount of sleep teenagers get varies between countries, geographic region and social class, but all studies show they are going to bed later and not getting as much sleep as they need because of early school starts. F) Mary Carskadon at Brown University in Providence. Rhode Island, who is a pioneer in the area of adolescent sleep, has shown that teenagers need about 9 hours a night to maintain full alertness and academic perforruance. My own recent observations at a UK school in Liverpool suggested many were getting just 5 hours on a school night. Unsurprisingly. teachers reported students dozing in class. G) Evidence that sleep is important is overwhelming. Elegant research has demonstrated its critical role in memory improvement and our ability to generate wise sohitions to complex problems. Sleep disruption may increase the level of the stress. Excited behaviors, lack of empathy, sense of humor and mood are similarly affected. All in all, a tired adolescent is a moody, insensitive, angry and stressed one. Perhaps less obviously, sleep loss is associated with metabolic (新陈代谢的) changes. Long-term lack of sleep might be an important factor for negative conditions such as diabetes (糖尿病), overweight and high blood pressure. H) Adolescents are increasingly using stimulants to compensate for sleep loss, and caf, feinated (含咖啡咽的) and/or sugary drinks are the usual choice. So a caffeinated drink late in the day delays sleep at night. Tiredness also increases the likelihood of taking up smoking. I) In the US, the observation that teenagers have biologically delayed sleep patterns compared to adults prompted several schools to put back the start of the school day. An analysis of the impact by Kyla Wahlstrom at the University of Minnesota found that academic performance was enhanced, as was attendance. Sleeping in class declined, as did self-reported depression. In the UK, Monkseaton High School near Newcastle instituted a 10 am start in 2009 and saw a progress in academic perfomance. J) However, a later start by itself is not enough. Society in general, and teenagers in particular, must start to take sleep seriously. Sleep is not a luxury but a ftmdamental biological need, enhancing creativity, productivity, mood and the ability to interact with others. K) ff you are dependent upon an alarm clock, or parent, to get you out of bed ; if you take a long time to wake up; if you feel sleepy and impatient during the day; ff your behavior. is overly impulsive, it means you are probably not getting enough sleep. Take control. Ensure the bedroom is a place that promotes sleep-dark and not too warm-dont text, use a computer or watch TV for at least half an hour before trying to sleep avoid avoid bright lights. Try not to nap during the day, and seek out natural light in the morning to adjust the body clock and sleep patterns to an earlier time. Avoid caffeinated drinks after lunch. L) It is my strongly held View, based upon the evidence, that the efforts of dedicated (专注的，投入的) teachers and the money spent on school facilities will have a greater impact and education will be more rewarding when, collectively, teenagers, parents, teachers and school governors start to take sleep seriously. In the universal language of school reports: we must do better. In the US and UK, several schools that have delayed the start of the school day witnessed a progress in academic performance.

Sleep Deficit（不足)Judging from recent surveys, most experts in sleep behavior. agree that

Sleep Deficit(不足)

Judging from recent surveys, most experts in sleep behavior. agree that is virtually an epidemic of sleepiness in the nation. "I can't think of a single study that hasn't found Americans getting less sleep than they ought to. " says Dr. David. Even people who think they are sleeping enough would probably be better off with more rest.

The beginning of our sleep-deficit crisis can be traced to the invention of the light bulb a century ago. From diary entries and other personal accounts from the 18th 19th centuries, sleep scientists have reached the conclusion that the average person used to sleep about 9. 5 hours a night. "The best sleep habits once were forced on us, when we had nothing to do in the evening down on the farm, and it was dark. " By the 1950s and 1960s, that sleep schedule had been reduced dramatically, to between 7. 5 and 8 hours, and most people had to wake to an alarm clock. "People cheat on their sleep, and they don't even realize they're doing it, " says Dr. David. "They think they're okay because they can get by on 6. 5 hours, when they really need 7. 5, 8 or even more to feel ideally vigorous. "

"Perhaps the most merciless robber of sleep, " researchers say, "is the complexity of the day. " Whenever pressures from work, family, friends and community mount, many people consider sleep the least expensive item on his program. "In our society, you're considered dynamic if you say you only need 5. 5 hours' sleep. If you've got to get 8. 5 hours, people think you lack drive and ambition. "

To determine the consequences of sleep deficit, researchers have put subjects through a set of psychological and performance tests requiring them, for instance, to add columns of numbers or re call a page read to them only minutes earlier. "We've found that if you're in sleep deficit, performance suffers, " says Dr. David. "Shot-term memory is weakened, as are abilities to make decision and to concentrate.

People in the 18th and 19th centuries used to sleep about 5 hours a night because they had ______.

A．no drive and ambition

B．no electric lighting

C．the best sleep habits

D．a lot to of the next day
