When it comes to the slowing economy, Ellen Spero isn' t biting her nails just yet. But the 47-year-old mani-curist isn' t cutting, filling or polishing as many nails as she' d like to, either. Most of her clients spend $12 to$ 50 weekly, but last month two longtime customers suddenly stopped showing up. Spero blames the softening e-conomy. "I'm a good economic indicator, " she says, "I provide a service that people can do without whenthey' re concerned about saving some dollars. " So Spero is downscaling, shopping at middle-brow Dillard' s de-partment store near her suburban Cleveland home, instead of Neiman Marcus. "I don' t know if other clients are go-ing to abandon me, too. " she says.
Even before Alan Greenspan' s admission that America' s red-hot economy is cooling, lots of working folks hadalready seen signs of the slowdown themselves. From car dealerships to gap outlets, sales have been lagging formonths as shoppers temper their spending. For retailers, who last year took in 24 percent of their revenue betweenThanksgiving and Christmas, the cautious approach is coming at a crucial time. Already, experts say, holiday salesare off 7 percent from last year' s pace. But don' t sound any alarms just yet. Consumers seem only concerned, notpanicked, and many say they remain optimistic about the economy' s long-term prospects, even as they do somemodest belt-tightening.
Consumers say they' re not in despair because, despite the dreadful headlines, their own fortunes still feel prettygood. In Manhattan, "there' s a new gold rush happening in the $ 4 million to $10 million range, predominantlyfed by Wall Street bonuses, " says broker Barbara Corcoran. In San Francisco, prices are still rising even as fren-zied overbidding quiets. "Instead of 20 to 30 offers, now maybe you only get two or three, " says John Deadly, aBay Area real-estate broker. And most folks still feel pretty comfortable about their ability to find and keep a job.Many folks see silver linings to this slowdown. Potential homebuyers would cheer for lower interest rates. Em-ployers wouldn' t mind a little fewer bubbles in the job market. Many consumers seem to have been influenced bystock-market swings, which investors now view as a necessary ingredient to a sustained boom. Diners might see actupside,, too. Getting a table at Manhattan' s hot new Alain Ducasse restaurant need to be impossible. Not anymore.For that, Greenspan & Co. may still be worth toasting.
By "Ellen Spero isn't biting her nails just yet" ( Line 1, Paragraph 1 ), the author means__________
A.Spero can hardly maintain her business
B.Spero is too much engaged in her work
C.Spero has grown out of her bad habit
D.Spero is not in a desperate situation
52、 How do the public feel about the current economic situation?
A.Optimistic.
B.Confused.
C.Carefree.
D.Panicked.
53、 When mentioning "the $ 4 million to $10 million range" ( Line 2, Paragraph 3 ) the author is talking a-bout
A.gold market
B.real estate
C.stock exchange
D.venture investment
54、 Why can many people see "silver linings" to the economic slowdown?
A.They would benefit in certain ways.
B.The stock market shows signs of recovery.
C.Such a slowdOwn usually precedes a boom.
D.The purchasing power would be enhanced.
55、 To which of the following is the author likely to agree?
A.A now boom, on the hodzou.
B.Tighten the belt, the single remedy.
C.Caution all right, panic not.

The Village Green in New Milford, Connecticut, is a snapshot of New England charm: a carefully manicured lawn flanked by scrupulously maintained colonial homes. Babysitters dandle kids in the wooden gazebo, waiting forcommuter parents to return from New York, On a lazy afternoon last week Caroline Nicholas, 16, had nothing morepressing to do than drink in the early-summer sunshine and discuss the recent events in town. " I don't think a lot ofolder people knew there were unhappy kids in New Milford, "she said, "I could see it coming. "
In a five-day period in early June eight girls were brought to New Milford Hospital after what hospital officialscall suicidal gestures. The girls, all between 12 and 17, tried a variety of measures, including heavy doses of alcohol,over-the-counter medicines and cuts or scratches to their wrists. None was successful, and most didn't require hospital-ization ;but at least two attempts, according to the hospital, could have been vital. Their reasons seemed as mundane asthe other happen-stances of suburban life. "I was just sick of it all, "one told a reporter, "Everything in life. "Mostalarming, emergency-room doctor Frederick Lohse told a local reporter that several girls said they were part of a sui-cide pact. The. hospital.later backed away from this remark. But coming in the wake of at least sixteen suicide at-tempts over the previous few months, this sudden cluster--along with the influx of media--has set this well-groomedsuburb of 23,000 on edge. At a town meeting last Wednesday night, Dr Simon Sobo, chief of psychiatry at the hospi-tal, told more than 200 parents and kids, "We're talking about a crisis that has really gotten out of hand. "Later headded, "There have been more suicide attempts this spring than I have seen in the 13 years I have been here. "
Sobo said that the girls he treated didn't have serious problems at home or school. "Many of these were popularkids, "he said, "They got plenty of love, but beneath the reassuring signs, a swath of teens here are not making it."Some say that drugs, Both pot and 'real drugs', are commonplace. Kids have shown up with LIFE SUCKS andLONG LIVE DEATH penned on their arms. A few girls casually display scars on their arms where they cut them-selves. "You'd be surprised how many kids try suicide, "said one girl, 17. "You don't want to put pain on otherpeople ;you put it on yourself. "She said she used to cut herself "just to release the pain".
Emily, 15, a friend of three of the girls treated in June, said one was having family problems, one was "upsetthat day "and the third was "just upset with everything else going on". She said they weren't really trying to killthemselves-they just nceded coucern. As Sobo noted, "What's going on in New Milford is not unique to NewMilford. "The same underlying culture of despair could be found in any town. But teen suicide, he added, can be a"contagion". Right now New Milford has the bug--and has it bad.
What is the main subject of the. passage?
A.Eight girls committed suicide in New Milford.
B.The village Green is not a charming place.
C.Teenager suicide.

The history of responses to the work of the artist Sandro Botticelli ( 1444 - 1510 ) suggests that widespreadappreciation by critics is a relatively recent phenomenon. Writing in 1550, Vasari expressed an unease with Botticel-li' s work, admitting that the artist fitted awkwardly into his evolutionary scheme of the history of art. Over the nexttwo centuries, academic art historians defamed Botticelli in favor of his fellows Florentine, Michelangelo. Evenwhen anti-academic art historians of the early nineteenth century rejected many of the standards of evaluation adoptedby their predecessors, Botticelli' s work remained outside of accepted taste, pleasing neither amateur observers norconnoisseurs. (Many of his best paintings, however, remained hidden away in obscure churches and privatehomes. )
The primary reason for Botticelli' s unpopularity is not difficult to understand: most observers, up until the mid-nineteenth century, did not consider him to be noteworthy, because his work, for the most part, did not seem tothese observers to exhibit the traditional characteristics of the fifteenth-century Florentine art. For example, Botticellirarely employed the technique of strict perspective and, unlike Michelangelo, never used chiaroscuro.
Another reason for Botticelli' s unpopularity may have been that his attitude toward the style of classical art wasvery different from that of his contemporaries. Although he was thoroughly exposed to classical art, he showed littleinterest in borrowing from the classical style. Indeed, it is paradoxical that a painter of large-scale classical subjectsadopted astyle that was only slightly similar to that of classical art.
In any case, when viewers began to examine more closely the relationship of Botticelli' s work to the traditionof the fifteenth century Florentine art, his reputation began to grow. Analyses and assessments of Botticelli made be-tween 1850 and 1870 by the artists of the Pre-Raphaelite movement, as well as by the writer Pater ( although he, un-fortunately, based his assessment on an incorrect analysis of Botticelli' s personality), inspired a new appreciation ofBotticelli throughout the English-speaking world. Yet Botticelli' s work, especially the Sistine frescoes, did not gen-erate worldwide attention until it was finally subjected to a comprehensive and scrupulous analysis by Home in 1908.Home rightly demonstrated that the frescoes shared important features with paintings by other fifteenth-century Flor-entines--features such as skillful representation of anatomical proportions, and of the human figure in motion. How-ever, Home argued that Botticelli did not treat these qualities as ends in themselves--rather, that he emphasizedclear depletion of a story, a unique achievement and one that made the traditional Florentine qualifies less central.
Because of Home' s emphasis crucial to any study of art, the twentieth century has come to appreciate Botticelli' s a-chievements.

66、回答66-95题：
With unfamiliar human beings, when we acknowledge their humanness, we must avoid staring at them, and yetwe must also avoid ignoring them. To make them into people rather than objects, we use a deliberate and polite inat-tention. We look at them long enough to, make it quite clear that we see them, and then we immediately look a-way.
66.__________
The important thing in such an exchange is that we do not catch the eye of one whom we are recognizing as aperson. We look at him without locking glances, and then we immediately look away. Recognition is not permitted.
67.__________
If you pass someone in the street, you may eye the oncoming person until you are about eight feet apart, thenyou must look away as you pass. Before the eight-foot distance is reached, each will signal in which direction hewill pass. This is done with a brief look in that direction. Each will veer slightly and the passing is done smoothly.
68.__________
To strengthen this signal, you look directly at the other's face before looking away.
69.__________
It becomes impossible to discover just what they are doing. Are they looking at you too long, too intently? Arethey looking at you at all? The person wearing the glasses feels protected and assumes that he can stare without beingnoticed in his stating. However, this is a self-deception. To the other person, dark glasses seem to indicate that thewearer is always stating at him.
We often use this look-away technique when we meet famous people. We want to assure them we are respectingtheir privacy and that we would not dream of staring at them. The same is true of the crippled or physically handi-capped. We look brief and then look away before the stare can be said to be a stare.
70.__________
Of course, the opposite is also true. If we wish to put a person down, we may do so by staring longer than isacceptably polite. Instead of dropping our gazes when we lock glances, we continue to stare. The person who disap-proves of interracial marriages or dating will stare rudely at the interracial couple. If he dislikes long hair, short dres-ses, or beards, he may show it with a longer-than-acceptable stare.
__________
A.There are different formulas for the exchange of glances depending on where the meeting takes place.
B.In the subway or bus where long rides in very close circumstances are a necessity, we may be hard put tofind some way of not staring. We sneak glances, but look away before our eyes can lock. If we look withan unfocused glance that misses the eyes and settles on the head, the mouth, the body for any place but theeyes is an acceptable looking spot for the unfocused glance.
C.Actually in this way we are saying, in body language, "I know you are there, "and a moment later we add, "But I would not dream of intruding on your privacy. "
D.It is the technique we use for any unusual situation where too long a stare would be embarrassing. When wesee an interracial couple, we also use tiffs technique. We might use it when we see a man with an unusualbeard, with extra longhair, with outlandish clothes, or a girl with a minimal miniskirt may attract this look-and-away.
E.For this passing encounter Dr. Erring Goffman in behavior in public places says that the quick look and thelowering of the eyes is body language for, "I trust you. I am not afraid of you. "
F.Sometimes the rules are hard to follow, particularly if one of the two people wears dark glasses.

introduction
We have used running water as an energy source for thousands of years, mainly to grind corn.
The first house in the world to be lit by hydroelectricity was Cragside House, in Northumberland, England, in 1878. In 1882 on the Fox River, in the USA, hydroelectricity produced enough power to light two paper mills and ahouse.
Nowadays there are many hydro-electric power stations, providing around 20% of the world's electricity, The name comes from "hydro", the Greek word for water.
How it works
A dam is built to trap water, usually in a valley where there is an existing lake.
Water is allowed to flow through tunnels in the darn, to turn turbines and thus drive generators.Advantages
Once the dam is built, the energy is virtually free.No waste or pollution produced.
Much more reliable than wind, solar or wave power.
Water can be stored above the dam ready to cope with peaks in demand.
Hydro-electric power stations can increase to full power very quickly, unlike other power stations.Disadvantages
The dams are very expensive to build.
Building a large dam will flood a very large area upstream, causing problems for animals that used to live there.Finding a suitable site can be difficult--the impact on residents and the environment may be unacceptable.
Water quality and quantity downstream can be affected, which can have an impact on plant life.Is it renewable?
Hydro-electric power is renewable,
The Sun provides the water by evaporation from the sea, and will keep on doing so.
B.Nuclear power
Introduction
Nuclear power is generated using Uranium, which is a metal mined in various parts of the world.The first large-scale nuclear power station opened at Calder Hall in Cambria, England, in 1956.Some military ships and submarines have nuclear power plants for engines.
How it works
Nuclear power stations work in pretty much the same way as fossil fuel-burning stations, except that a "chain reaction" inside a nuclear reactor makes the heat instead.
The reactor uses Uranium rods as fuel, and the heat is generated by nuclear fission. Neutrons smash into the nu-cleus of the uranium atoms, which split roughly in half and release energy in the form of heat.
Carbon dioxide gas is pumped through the reactor to take the heat away, and the hot gas then heats water to make steam.
Advantages
Nuclear power costs about the same as coal, so it' s not expensive to make.
Does not produce smoke or carbon dioxide, so it does not contribute to the greenhouse effect.Produces huge amounts of energy from small amounts of fuel.
Produces small amounts of waste.Disadvantages
Although not much waste is produced, it is very, very dangerous.
It must be sealed up and buried for many years to allow the radioactivity to die away.Nuclear power is reliable, but a lot of money has to be spent on safety.
Is it renewable?
Nuclear energy from Uranium is not renewable.
Once we' ve dug up all the Earth' s uranium and used it, there isn' t any more.
C.Solar power
Introduction
We' ve used the Sun for drying clothes and food for thousands of years, but only recently have we been able to use it for generating power.
The Sun is 150 million kilometers away, and amazingly powerful.
Just the tiny fraction of the Sun' s energy that hits the Earth ( around a hundredth of a millionth of a percent) is enough to meet all our power needs many times over.
How it works
There are three main ways that we use the Sun' s energy:
Solar Cells (really called "photovoltaic" or "photoelectric" cells) that convert light directly into electricity.
In a sunny climate, you can get enough power to run a 100W light bulb from just one square meter of solar panel.This was originally developed in order to provide electricity for satellites, but these days many of us own calcu-lators powered by solar cells.
Solar water heating, where heat from the Sun is used to heat water in glass panels on your roof.This means you don' t need to use so much gas or electricity to heat your water at home.
Solar Furnaces use a huge array of mirrors to concentrate the Sun' s energy into a small space and produce very high temperatures.AdvantagesSolar energy is free--it needs no fuel and produces no waste or pollution.
In sunny countries, solar power can be used where there is no easy way to get electricity to a remote place.Handy for low-power uses such as solar powered garden lights and battery chargers.
Disadvantages
Doesn' t work at night.
Very expensive to build solar power stations.
Solar cells cost a great deal compared to the amount of electricity they' 11 produce in their lifetime.Can be unreliable unless you' re in a very sunny climate.
Is it renewable?
Solar power is renewable. The Sun will keep on shining anyway, so it makes sense to use it.
D.Wind power
Introduction
We' ve used the wind as an energy source for a long time. The Babylonians and Chinese were using wind pow-er to pump water for irrigating crops 4,000 years ago, and sailing boats were around long before that.
Wind power was used in the Middle Ages, in Europe, to grind corn, which is where the term "windmill" comes from.
How it works
The Sun heats our atmosphere unevenly, so some patches become warmer than others.
These warm patches of air rise, other air blows in to replace them--and we feel a wind blowing.
We can use the energy in the wind by building a tall tower, with a large propeller on the top. The wind blows the propeller round, which turns a generator to produce electricity.
The more towers, the more wind, and the larger the propellers, the more electricity we can make.
Advantages
