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.

Because it can take many hours to eliminate caffeine from the body, Ohayon recommends that coffee lovers switch to decal after lunch.

The author mentions" pick-me-up" to indicate that 查看材料

回答题。

Stanford University

1. Stanford University, famous as one of northern California&39;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&39;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 Panling in chemistry. The Russian novelist Aleksandr Solzhenistsyn has been in residence. Stanford&39;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&39;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&39;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 government 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 Stanford Foundation&39;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.

根据以下材料，回答题。

The Only Way Is U p

Think of a modem city and the first image that come to mind is the skyline.It is full of great buildings，pointing like fingers to heaven.It is true that some cities don’t permit buildings to go above a certain height.But these are cities concerned with the past.The first thing any city does

when it wants to tell the world that it has arrived is to build skyscrapers.

When people gather together in cities，they create a demand for land.Since cities are places where money is made，that demand can be met.And the best way to make money out of city land is to put as many people as possible in a space that covers the smallest amount of ground.That means building upwards.

The technology existed to do this as early as the l9thcentury.But the height of buildings was limited by one important factor.They had to be small enough for people on the top floors to climb stairs.People could not be expected to climb a mountain at the end of their journey to work，or home.

Elisha Otis，a US inventor，was the man who brought us the lift—or elevator，as he preferred to call it.However，most of the technology is very old.Lifts work using the same pulley system the Egyptians used to create the Pyramids.What Otis did was attach the system to a steam engine and develop the elevator brake.which stops the lift falling if the cords that hold it up are broken.It was this that did the most to gain public confidence in the new invention.In fact，he spent a number of years exhibiting lifts at fairgrounds，giving people the chance to try them before selling the idea to architects and builders.

A lift would not be a very good theme park attraction now.Going in a lift is such an everyday thing that it would just be borin9.Yet psychologists and others who study human behavior. find lifts fascinatin9.The reason is simple.Scientists have always studied animals in zoos.The nearest they can get to that with humans is in observing them in lifts.

“It breaks all the usual conventions about the bubble of personal space we carry around with us—and you just can’t choose to move away”，says workplace psychologist，Gary Fitzgibbon.Being trapped in this setting can create different types of tensions，he says.Some people are scared of them.Others use them as an opportunity to get close to the boss.Some stand close to the door.Others hide in the corners.Most people try and shrink into the background.But some behave in a way that makes others notice them.There are a few people who just stand in a corner taking notes.

Don’t worry about them.They are probably from a university.

“…these are cities concerned with the past”in the first paragraph refer to cities that 查看材料

A.are worried about their past

B.have a glorious past to be proud of

C.want to maintain their traditional image

D.are very interested in their own history

Middle Age: A Low Point for Most

People around the globe hit the height of their misery and depression in middle 51_________ .， a new international study suggests. The finding by British and American researchers was based on an analysis of well-being among approximately 52_________ million people in 80 nations. With few exceptions，the observation appears to apply across the board， regardless 2 gender （性别）， culture，geography， wealth， job history， education， and marriage or parental status.

"The scientific fact seems to be that happiness and positive mental health follow a giant "U" 53_________ through life，" said study author Andrew J. Oswald， a professor of economics at Warwick University in Warwickshire， England. "For the average person， it"s high when you"re 20， and then it slowly 54_________ and bottoms out in your 40s. But the good news is that your 55_________ health picks up again， and eventually gets back to the high levels of your youth."

The finding was 56_________ on the pooling of several different sources of happiness data，including: two multi-decade happiness/satisfaction surveys （first launched in the 1970s）， involving about 500，000 American and Western European men and women; four rounds of the 80-nation "World Values Survey" 57_________ between 1981 and 2004 in North America， Eastern and WesternEurope， Asia， Africa， Australia， and Central and South America; and a 2004-2007 survey 58_________ nearly 1 million Britons.

The bottom-line: For most people throughout the world， the highest probability for 59_________ striking is around 44 years of age.

In the United States， however， some as-yet unexplained 60_________ differences were observed， with happiness among men dipping the most in their early 50s， whereas women hit their nadir （最低点） around the age of 40.

The researchers cautioned that cheerful people tend to live longer than unhappy. 61_________ – a fact that might have skewed （使偏斜） the overall finding. But they also suggested that evidence of a happiness 62_________ might simply reflect a midlife choice to give up long-held but no longer tenable （守得住的） aspiration （志向）， followed by a senior"s sense of gratitude for having successfully endured 63_________ others did not.

"That said， some might find it helpful simply to understand the general 64_________ of mental health as they go through their own life，" said Oswald. "It might be useful for people to realize that if they are 65_________ in their 40s this is normal. It is not exceptional. And just knowing this might help".

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
