根据以下材料，回答题

Stanford University

（1） Stanford University， famous as one of northern California"s several institutions of higher learning， is sometimes called "the Harvard of the West". The closeness of Stanford to San Francisco， a city thirty-two miles to the north， gives the university a decidedly cosmopolitan（世界性的） flavor.

（2） The students are enrolled mainly from the western United States. But most of the fifty states send students to Stanford， and many foreign students study here， as well. And standards for admission remain high. Young men and women are selected to enter the university from the upper fifteen percent of their high school classes.

（3） Not only because of the high caliber （素质） of its students but also because of the desirable location and climate， Stanford has attracted to its faculty some of the world"s most respected scholars. The university staff has included many Nobel prize winners such as Dr. Felix Bloch，Dr. Robert Hofstadter， and Dr. William Shockley in physics. Dr. Author Kornberg and Dr.Joshua Lederberg in medicine， and Dr. Paul J. Flory and Dr. Linus Pauling in chemistry. The Russian novelist Aleksandr Solzhenistsyn has been in residence. Stanford"s undergraduate school of engineering and its graduate schools of business， law， and medicine are especially well-regarded.

（4） What is student life like on "The Farm"？ Culturally， the campus is a magnet for both students and citizens of nearby communities. Plays， concerts， and operas are performed in the university"s several auditoriums and in its outdoor theater， where graduations are also held.

Several film series are presented during the school year. Guest lecturers from public and academic life frequently appear on campus. In the evenings， many students gather to socialize in the Student Union"s coffee house; here the beverages （饮料） and the atmosphere both have a decidedly European flavor. For the sports-minded， the Stanford campus offers highly developed athletic facilities. Team spots， swimming， and track and field activity are all very much part of the Stanford picture. So are bicycling and jogging.

（5） In addition to financial support from alumni （校友）， Stanford receives grants from the govemment and from private philanthropic （慈善的） foundations. In recent years， government grants have made possible advanced studies in the fields of history， psychology， education，and atomic energy. At present Stanford is carrying out an ambitious building program，financed in part by Ford Foundation"s 25 million grant. Recently added to the campus are a new physics building， new school of business， new graduate school of law， new student union， and undergraduate library.

Paragraph 2 ___________ 查看材料

A.Colorful life on campus

B.Intelligent student body

C.School administration

D.Distinguished faculty

E.Substantial financial support

F.The Harvard of the west

Late-Night Drinking

Coffee lovers beware. Having aquick" pick-me-up" cup of coffee late in the day will playhavocwith your sleep. As well as being astimulant, caffeine interrupts the flow of melatonin, theB．rain hormone that sends people into asleep.

Melatonin levels normally start to rise about two hours before bedtime. Levels then peak be-tween 2 am and 4 am, before failing again. "It&39;s the neurohormone that controls our sleep tells ourB．ody when to sleep and when to wake, "says Maurice Ohayon of the Stanford Sleep EpidemiologyResearch Center at Stanford University in California. but researchers in Israel have found that caf-feinated coffee halves the body&39;s levels of this sleep hormone.

Lotan Shilo and ateam at the Sapir Medical Center in Tel Aviv University found that six vol-unteers slept less well after acup of caffeinated coffee than after drinking the same amount of de-caf. On average, subjects slept 336 minutes per night after drinking caffeinated coffee, comparedwith 415 minutes after decaf. They also took half an hour to drop off--twice as long as usual--andjigged around in bed twice as much.

In the second phase of the experiment, the researchers woke the volunteers every three hoursand asked them to give aurine sample. Shilo measured concentrations of abreakdown product ofmelatonin. The results suggest that melatonin concentrations in caffeine drinkers were half those indecaf drinkers. In apaper accepted for publication in Sleep Medicine, the researchers suggest thatcaffeine blocks production of the enzyme that drives tnelatonin production.

Late-Night Drinking

根据内容回答题.

Coffee lovers beware. Having a quick "pick-me-up" cup of coffee late in the day will play havoc with your sleep. As well as being a stimulant, caffeine interrupts the flow of melatonin, the brain hormone that sends people into a sleep.

Melatonin levels normally start to rise about two hours before bedtime. Levels then peak be-

tween 2 a.m. and 4 a. m. , before falling again. "It&39;s the neurohormone that controls our sleep and tells our body when to sleep and when to wake," says Maurice Ohayon of the Stanford Sleep Epidemiology Research Center at Stanford University in California. But researchers in Israel have found that caffeinated coffee halves the body&39;s levels of this sleep hormone.

Lotan Shilo and a team at the Sapir Medical Center in Tel Aviv University found that six vol-

unteers slept less well after a cup of caffeinated coffee than after drinking the same amount of de- caf(脱因咖啡). On average, subjects slept 336 minutes per night after drinking caffeinated cof- fee, compared with 415 minutes after decaf. They also took half an hour to drop off—twice as long as usual--and jigged aroused in bed twice as much.

In the second phase of the experiment, the researchers woke the volunteers every three hours and asked them to give a urine sample, Shilo measured concentrations of a breakdown product of melatonin. The results suggest that melatonin concentrations in caffeine drinkers were half those in decaf drinkers. In a paper accepted for publication in Sleep Medicine, the researchers suggest that caffeine blocks production of the enzyme that drives melatonin production.

A Sunshade for the Planet

Even with the best will in the world, reducing our carbon emissions is not going to prevent global warming. It has become clear that even if we take the strongest measures to control emissions, the uncertainties in our climate models still leave open the possibility of extreme warming and rises in sea level. At the same time, resistance by governments and special interest groups makes it quite possible that the actions suggested by climate scientists might not be implemented soon enough.＜br＞

Fortunately, if the worst comes to the worse, scientists still have a few tricks up their sleeves.＜br＞

For the most part they have strongly resisted discussing these options for fear of inviting a sense of complacency that might thwart efforts to tackle the root of the problem. Until now, that is. A growing number of researchers are taking a fresh look at large-scale "geoengineering" projects that might be used to counteract global warming. "I use the analogy of methadone," says Stephen Schneider, a climate researcher at Stanford University in California who was among the first to draw attention to global warming. "If you have a heroin addict, the correct treatment is hospitalization, and a long rehab. But if they absolutely refuse, methadone is better than heroin."＜br＞

Basically the idea is to apply "sunscreen" to the whole planet. One astronomer has come up with a radical plan to cool Earth: launch trillions of feather-light discs into space, where they would form. a vast cloud that would block the sun&39;s rays. It&39;s controversial, but recent studies suggest there are ways to deflect just enough of the sunlight reaching the Earth&39;s surface to counteract the warming produced by the greenhouse effect. Global climate models show that blocking just 1.8 per cent of the incident energy in the sun&39;s rays would cancel out the warming effects produced by a doubling of greenhouse gases in the atmosphere. That could be crucial, because even the most severe emissions-control measures being proposed would leave us with a doubling of carbon dioxide by the end of this century, and that would last for at least a century more.

According to the first two paragraphs， the author thinks that __________. 查看材料

A.strong measures have been taken by the government to prevent global warming

B.to reduce carbon emissions is an impossible mission

C.despite the difficulty， scientists have some options to prevent global Warming

D.actions suggested by scientists will never be realized

On line courses （also called distance learning) are a hot new trend in American education.

On line courses (also called distance learning) are a hot new trend in American education. According to the nonprofit Distance Education and Training Council, about 400 US colleges and schools offer some portion of their programs on the We b. At the university level, they cost the same as traditional classes and requir e similar weekly assignments and textbook reading, the difference is in class pa rticipation. Generally speaking, students congregate(使聚集) on line throughout each week to explore topic with the professor, but these discussions occur “asynchronously(不同时发生地)”rather than in real time. (You read others’ comments and post your own whenever you get a chance.) Written assignments are posted, you email in your work periodically, and you’re required to take a proctored exam in order to receive degree credit. Career boosting business administration and information technology programs are the most popular, but you’ll also find a variety of literal arts offerings, from film theory to medieval history and foreign lang uage study. While you still can’t get an Ivy League degree on line, a growing number of elite(卓越的) institutions, including Stanford and New York Univer sity are beginning to offer on line courses. The benefits for busy people are obvious. “I always get a front row seat,” says one student studying at the State University of New York Learning Network. “I can get up in the middle of class, grab a cup of coffee. The class is waiting for me when I get back, and I haven’t missed a thing.” On the other hand, some students miss the face to face interaction that often sparks interest and involvement. Generally speaking, on line education costs ____.

A.more than the traditional one

B.less than the traditional one

C.as much as the traditional one

D.the author hasn’t mentioned

Computer Mouse

The basic computer mouse is an amazingly clever invention with a relatively simple design that allows us to point at things on the computer and it is very productive. Think of all the things you can do with a mouse like selecting text for copying and pasting, drawing, and even scrolling on the page with the newer mice with the wheel. Most of us use the computer mouse daily without stopping to think how it works until it gets dirty and we have to learn how to clean it. We learn to point at things before we learn to speak, so the mouse is a very natural pointing device. Other computer pointing devices include light pens, graphics tablets and touch screens, but the mouse is still our workhorse.＜br＞

The computer mouse was invented in 1964 by Douglas Engle hart of Stanford University. As computer screens became more popular and arrow keys were used to move around a body of text, it became clear that a pointing device that allowed easier motion through the text and even selection of text would be very useful. The introduction of the mouse, with the Apple Lisa computer in 1983,really started the computer public on the road to relying on the mouse for routine computer tasks.＜br＞

How does the mouse work？ We have to start at the bottom, so think upside down for now. It all starts with the mouse ball. As the mouse ball in the bottom of the mouse rolls over the mouse pad, it presses against and turns two shafts. The shafts are connected to wheels with several small holes in them. The wheels have a pair of small electronic light-emitting devices called light-emitting diodes (LED) mounted on either side. One LED sends a light beam to the LED on the other side. As the wheels spin and a hole rotates by, the light beam gets through to the LED on the other side. But a moment later the light beam is blocked until the next hole is in place. The LED detects a changing pattern of light, converts the pattern into an electronic signal, and sends the signal to the computer through wires in a cable that goes out of the mouse body. This cable is the tail that helps give the mouse its name. The computer interprets the signal to tell it where to position the cursor on the computer screen.＜br＞

So far we have only discussed the basic computer mouse that most of you probably have or have used. One problem with this design is that the mouse gets dirty as the ball rolls over the surface and picks up dirt. Eventually you have to clean your mouse. The newer optical mice avoid this problem by having no moving parts.

Most computer users want to know how the computer mouse works. 查看材料

回答题。 DreamsOf all the components of a good night&39;s sleep, dreams seem to be least

回答题。

Dreams

Of all the components of a good night&39;s sleep, dreams seem to be least within our control. In dreams, a window opens into a world where logic is suspended and dead people speak. A century ago, Freud formulated this revolutionary theory that dreams were the disguised shadows of our unconscious desires and fears; by the

late 1970s, neurologists had switched to thinking of them as just "mental noise" -- the random byproducts of the neural-repair work that goes on during sleep. Now researchers suspect that dreams are part of the mind&39;s emotional thermostat, regulating moods while the brain is "off-line" . And one leading authority says that these intensely powerful mental events can be not only harnessed but actually brought under conscious control, to help us sleep and feel better. "It&39;s your dream, " says Rosalind Cartwright, chair of psychology at Chicago&39;s Medical Center, "If you don&39;t like it, change it. "

Evidence from brain imaging supports this view. The brain is as active during REM (rapid eye movement ) sleep --when most vivid dreams occur -- as it is when fully awake, says Dr. Eric Nofzinger at the University of Pittsburgh. But not all parts of the brain are equally involved; the limbic system (the "emotional brain" ) is especially active, while the prefrontal cortex (the center of intellect and reasoning ) is relatively quiet. "We wake up from dreams happy or depressed, and those feelings can stay with us all day, " says Stanford sleep researcher Dr. William Dement.

The link between dreams and emotions shows up among the patients in Cartwright&39;s clinic. Most people seem to have more bad dreams early in the night, progressing toward happier ones before awakening, suggesting that they are working through negative feelings generated during the day. Because our conscious mind is occupied with daily life we don&39;t always think about the emotional significance of the day&39;s events -until, it appears, we begin to dream.

And this process need not be left to the unconscious. Cartwright believes one can exercise conscious control over recurring bad dreams. As soon as you awaken, identify what is upsetting about the dream. Visualize how you would like it to end instead; the next time it occurs, try to wake up just enough to control its course. With much practice people can learn to, literally, do it in their sleep.

At the end of the day, there&39;s probably little reason to pay attention to our dreams at all unless they keep us from sleeping or "we wake up in panic, " Cartwright says. Terrorism, economic uncertainties and general feelings of insecurity have increased people&39;s anxiety. Those suffering from persistent nightmares should seek

help from a therapist. For the rest of us, the brain has its ways of working through bad feelings. Sleep—or rather dream -- on it and you&39;ll feel better in the morning.

Researchers have come to believe that dreams__________ 查看材料

A.can be modified in their courses

B.are susceptible to emotional changes

C.reflect our innermost desires and fears

D.are a random outcome of neural repairs
