The longest bull run in a century of art-market history ended on a dramatic note with a sale of 56 works by Damien Hirst, Beautiful Inside My Head Forever, at Sotheby's in London on September 15th, 2008．All but two pieces sold, fetching more than ￡ 70m, a record for a sale by a single artist. It was a last victory. As the auctioneer called out bids, in New York one of the oldest banks on Wall Street, Lehman Brother, filed for bankruptcy.
The world art market had already been losing momentum for a while after rising bewilderingly since 2003．At its peak in 2007 it was worth some $ 65 billion, reckons Clare McAndrew, founder of art Economics, a research firm-double the figure five year earlier. Since then it may have come down to $ 50 billion. But the market generates interest far beyond its size because it brings together great wealth, enormous egos, greed, passion and controversy in a way matched by few other industries.
In the weeks and months that followed Mr Hirst's sale, spending of any sort became deeply unfashionable. In the art world that meant collectors stayed away from galleries and salerooms. Sales of contemporary art fell by two-thirds, and in the most overheated sector, they were down by nearly 90% in the year to November 2008．Within weeks the world's two biggest auction houses, Sotheby's and Christie's, had to pay out nearly $ 200m in guarantees to clients who had placed works for sale with them.
The current downturn in the art market is the worst since the Japanese stopped buying Impressionist at the end of 1989．This time experts reckon that prices are about 40% down on their peak on average, though some have been far more fluctuant. But Edward Dolman, Christie's chief executive, says: "I'm pretty confident we're at the bottom. "
What makes this slump different from the last, he says, is that there are still buyers in the market. Almost everyone who was interviewed for this special report said that the biggest problem at the moment is not a lack of demand but a lack of good work to sell. The three Ds--death, debt and divorce-still deliver works of art to the market. But anyone who does not have to sell is keeping away, waiting for confidence to return.
In the first paragraph, Damien Hirst's sale was referred to as "a last victory" because______.
A．the art marker had witnessed a succession of victories
B．the auctioneer finally got the two pieces at the highest bids
C．Beautiful inside My Head Forever won over all masterpieces
D．it was successfully made just before the world financial crisis

Summer is winding down, but it's still not too late to put the top down and hit the road. For those of us who can't spring for a Corvette or a BMW, here's some good news: Two of the coolest convertibles on the road are also more affordable-- Volkswagen's New Beetle and Chrysler's PT Cruiser.
Both start at about $20,000, seat four, and get between 22 and 24 miles per gallon from their four-cylinder engines. Each has fully insulated cloth tops with rear windows made of real glass, which makes them comfort- able to use in winter. Front-wheel drive helps make them safer to drive over snow and ice. Both also offer high- performance turbocharged models starting at about $25,000. Both have bulging fenders and cool, retro personalities.
Beyond that, they're very different. The PT Cruiser focuses on practicality, while the Beetle is more fun to drive.
That fun comes from the car's chassis, suspension, and overall structure. Crank the steering into a turn and the Car follows like an eager puppy. The engine isn't powerful, but loves to rev, so you can downshift to accelerate.
The New Beetle Convertible has developed an unfortunate reputation as a "chick car" for its cute looks and the lack of power in the standard model. But for an extra $1,600, VW offers its turbocharged version, with a 150 horsepower, 1.8 liter engine, which gives the car some snap.
Even so, the convertible top eliminates what little practicality the New Beetle hatchback offers. To fit the folding top, the back seat was narrowed and angled so upright it's uncomfortable. And the folded top sits above a tiny trunk, with only five cubic feet of capacity and accessible through a smaller porthole.
Weekend trippers had better not have kids --or plan to rough it with more than a backpack or two. Interior storage is also minuscule. As with the New Beetle hatchback, the windshield is disconcertingly far away, and the wipers clear only a small slit of a view in front. Compared with the profile of the hatchback, however, the convertible sports a top that' s lower and a little less cartoonlike.
The PT Cruiser, on the other hand, looks its sinister best with the top up. Peeling the top off reveals its cutesy "roll hoop". (Chrysler denies the hoop offers rollover protection and calls it a light bar.) But the Cruiser, like its four-door brethren, offers all the year-round practicality the original Beetle convertible did in its day. The back seat is comfortable for two people, and the trunk is roomy.
Unfortunately, it's also hard to access because the big trunk lid gets in the way when open. So instead of standing to load or unload the car, you have to squat or kneel. But the storage space is huge --the biggest I've seen in any convertible. And the back seats fold forward in case you need to carry some long cargo. The interior offers four cup holders and several large storage bins.
The 220-horsepower turbocharged engine in the GT model makes the Cruiser seriously quick, which backs up its hot-rod looks. But after that, the driving experience falls apart. Like its hot-rod inspirations, the Cruiser is best on a straight, smooth road. Over bumps, its floppy chassis wobbles like jello. On the highway, the Cruiser I tested needed continual corrections to stay in its lane. The manual shifter on the GT proved sloppy; it was hard to be sure which gear the car was about to engage. Several times I hit fifth gear when aiming for third. Chrysler apparently anticipated this problem, as a brief warning chimes to let you know when you're in reverse.
Neither the PT Cruiser convertible nor the New Beetle is perfect. But for fun in the sun or even the fall -- what could be better？ Both cars brought constant waves, smiles, and stories from passersby.
What's a convertible about if it isn't looking good on the road and brightening your day？
Those who choose Volkswagen's Ne
A．practicality
B．fun to drive
C．prices
D．style

The phrase "litmus test" is in bad odor for good reason: politicians should be judged on a variety of positions, not just one. But deep down, nearly every voter has at least one litmus test— an issue so personally important that a politician who fails the test is forever tainted, or at least excluded from consideration for the presidency.
I inherited my one litmus test from my father, Jim Alter, who flew 33 harrowing missions over Nazi Germany during World War 11. My father is not just a veteran who by all odds should not have survived. He is a true patriot. His litmus test is the proposal to amend the Constitution to ban flag burning, which will come up for a vote next week in the U. S. Senate. For dad—and me—any member of Congress who supports amending the Bill of Rights for the first time in the history of this country for a nonproblem like flag burning is showing serious disrespect for our Constitution and for the values for which brave Americans gave their lives. Such disrespect is a much more serious threat than the random idiots who once every decade or so try (often unsuccessfully) to burn a flag.
Our understandable outrage at flag burning shouldn't turn our brains to mush. "I feel the same sense of outrage, but I would not amend that great shield of democracy (the Constitution) to hammer a few miscreants," Colin Powell said when the issue last came up (his position has not changed). "The flag will be flying proudly long after they have slunk away." Powell argues that a constitutional ban on flag burning is a sign of weakness and fear.
John Glenn, another of the thousands of combat veterans against the amendment (they have banded together in a group called Veterans Defending the Bill of Rights), notes that "those 10 amendments we call the Bill of Rights have never been changed or altered by one iota, not by one word, not a single time in all of American history. There was not a single change during any of our foreign wars, and not during recessions or depressions or panics. Not a single change when we were going through times of great emotion and anger like the Vietnam era, when flag after flag was burned or desecrated. There is only one way to weaken our nation. The way to weaken our nation would be to erode the freedom that we all share."
Actually, even during the Vietnam War, flag burning was rare. By one count, there have been only 45 such incidents in 200 years, and fewer than half a dozen since it was outlawed in 1989. Should the Constitution be amended, however, the incidence of flag burning is expected to surge as a form. of civil disobedience. What began as a phony issue designed to prove patriotism (usually on the part of those who never served, the primary sponsors) could become a real concern.
The flag-burning amendment, which already passed the House, is apparently just short of the 67 needed in the Senate. With one or two absences, the amendment would be approved. It would then go to the states for ratification, where its chances for approval appear good.
Senators afraid of being seen as soft on flag burners should just adopt the Hillary Clinton dodge: support for a statute, but not an amendment. Another law is a dopey idea (an earlier one was struck down by the Supreme Court), but it's politically safe and better than perverting the Constitution.
To make matters worse, the amendment is vaguely worded, which led to fatuous debate in the Senate over whether a woman wearing a skimpy bathing suit patterned with stars and stripes was guilty of desecration. Bloggers wondered the same thing about President Bush's new habit of autographing flags when he shakes hands on rope lines. Unconstitutional？ With a war on and a hundred other pressing problems, it's nice to see our elected representatives focused on what really counts.
The usual litmus tests-abortion, gun control, Iraq-shouldn't be. Reasonable and sincere people can disagree, w
A．The effectiveness of litmus test is greatly undermined by its failure to judge politicians on a variety of positions.
B．It's unfair to exclude a politician who fails a certain litmus test from the presidency.
C．Current litmus tests like abortion or gun control are not reliable indicators of public opinions.
D．Some specific litmus tests on certain issues axe fundamental in shaping people' s judgment of politicians.

It is 3 A. M. Everything on the university campus seems ghostlike in the quiet, misty darkness -- everything except the computer center. Here, twenty students untidy and blurred-eyed, sit transfixed at their consoles([计]挖制台), tapping away on the terminal keys. With eyes glued to the video screen, they tap on for hours. For the rest of the world, it might be the middle of the night, but here time does not exist. This is a world unto itself. These young computer "hackers" are pursuing a kind of impulse, a drive so consuming it overshadows nearly every other part of their lives and forms the focal point of their existence. They are compulsive computer programmers. Some of these students have been at the console for thirty hours or more without a break for meals or sleep. Some have fallen asleep on sofas or chairs in the computer center, trying to catch a few winks but hate to get too far away from their beloved machines.
Most of these students don't have to be at the computer center in the middle of the night. They aren't working on assignments. They are there because they want to be -- they are irresistibly drawn there.
And they are not alone. There are hackers at computer centers all across the country. In their extreme form, they focus on nothing else. They flunk(考试不及格)out of school and lose contact with friends; they might have difficulty finding jobs, choosing instead to wander from one computer center to another. They may even decline personal cleanliness.
"I remember one hacker. We literally had to carry him off his chair to feed him and put him to sleep. We really feared for his health," says a computer science professor at MIT.
Computer science teachers are now more aware of the implications of this hacker phenomenon and are
on the lookout for potential hackers and cases of computer addiction that are already severe. They know that the case of the hackers is not just the story of one person's relationship with a machine. It is the story of a society's relationship to the so-called thinking machines, which are becoming almost everywhere.
We can learn from the passage that those at the computer center in the middle of the night are ______.
A．students preparing for tests
B．students using computers to finish assignments
C．excellent computer science majors
D．students deeply fascinated by the computer

John Preston lives in a flat in north London. He moved there after his wife died four years ago to be close to his daughter’s family, and because his big detached house and garden were too much work for him as he got older. It’s easier in the flat because the letting agent does everything that needs doing. The agent has the not satisfied because the window frames need painted two years ago, but the painters didn’t do it very well, so they need doing again. John pays over ￡1,500 a year for service and maintenance, and he thinks that it’s not good enough because the flats look shabby and a lot of things need repairing.
His daughter June, and her husband, Pete, on the other hand, have to do everything themselves or find builders to do it. They live in a large semi-detached house further out from the center of London than John, but they are still near enough to see him often. They live in the suburbs with a nice garden when their children play. They moved there four years ago to have more space. The only drawback is that June’s husband has to commute into the centre of London every day, but, overall, they are happy with their decision. When they bought the house, a lot needed doing to it and still does. June says, “We have a list of things to do as long as your arm-the roof needs repairing and the chimney needs mending. The bedrooms need decorating and we haven’t had the broken windowpanes replaced yet in the conservatory. We need to fix the gate and repair the path-it looks dreadful when you arrive.
