【单选题】

Imagine a chart that begins when man first appeared on the planet and tracks the economic growth of societies from then forward. It would be a long, flat line until the late 16th or early 17th century, when it would start trending upward. For most of humankind life was as the English philosopher Thomas Hobbes famously described it in 1651—"solitary, poor, nasty, brutish, and short." But as Hobbes was writing those words, the world around him was changing. Put simply, human beings were getting smarter.
People have always sought knowledge. The scientific revolution, followed by the Enlightenment, marked a fundamental shift. Humans were no longer searching for ways simply to fit into a natural or divine order; but they were seeking to change it. Once people found ways to harness energy—using steam engines—they were able to build machines that harnessed far more power than any human or horse could ever do. And people could work without ever getting tired. The rise of these machines drove the Industrial Revolution, and created a whole new system of life. Today the search for knowledge continues to produce an ongoing revolution in the health and wealth of humankind.
If the rise of science marks the first great trend in this story, the second is its diffusion. What was happening in Britain during the Industrial Revolution was not an isolated phenomenon. A succession of visitors to Britain would go back to report to their countries on the technological and commercial innovations they saw there. Sometimes societies were able to learn extremely fast, as in the United States. Others, like Germany, was benefited from starting late, leapfrogging the long-drawn-out process that Britain went through.
This diffusion of knowledge accelerated dramatically in recent decades. Over the last 30 years we have watched countries like Japan, Singapore, South Korea and now China grow at a pace that is three times that of Britain or the United States at the peak of the Industrial Revolution. They have been able to do this because of their energies and exertions, of course, but also because they cleverly and perhaps luckily adopted certain ideas about development that had worked in the West—reasonably free markets, open trade, a focus on science and technology, among them.
The diffusion of knowledge is the dominant trend of our time and goes well beyond the purely scientific. Consider the cases of Turkey and Brazil. If you had asked an economist 20 years ago how to think about these two countries, he would have explained that they were classic basket-case, Third World economies, with triple-digit inflation, soaring debt burdens, a weak private sector and snail’s-pace growth. Today they are both remarkably well managed, with inflation in single digits and growth above 5 percent. And this shift is happening around the world. From Thailand to South Africa to Slovakia to Mexico, countries are far better managed economically than they have ever been. Even in cases where political constraints make it difficult to push far-reaching reforms, as in Brazil, Mexico or India, governments still manage their affairs sensibly, observing the Hippocratic oath not to do any harm.
We are sometimes reluctant to believe in progress. But the evidence is utakable. The management of major economies has gotten markedly better in the last few years. Careful monetary policy has tempered the boom-and-bust economic cycles of the industrial world, producing milder recessions and fewer shocks. Every day one reads of a new study comparing nations in everything from Internet penetration to inflation. All these studies and lists are symbols of a learning process that is accelerating, reinforcing the lessons of success and failure. Call it a best-practice world.
I realize that the world I am describing is the world of the winners. There are billions of people, locked outside global markets, whose lives are still accurately described by Hobbes’s cruel phrase. But even here, there is change. The recognition of global inequalities is more marked today than ever before, and this learning is forcing action. There is more money being spent on vaccines and cures for diseases in Africa and Asia today than ever before in history. Foreign-aid programs face constant scrutiny and ysis. When things don’t work, we learn that, too, and it puts a focus either on the aid program or on local governments to improve.
This may sound overly optimistic. There are losers in every race, but let not the worries over who is winning and losing the knowledge race obscure the more powerful underlying dynamic: knowledge is liberating. It creates the possibility for change and improvement everywhere. It can create amazing devices and techniques, save lives, improve living standards and spread information. Some will do well on one measure, others on another. But on the whole, a knowledge-based world will be a healthier and richer world.
The caveat I would make is not about one or another country’s paucity of engineers or computers. These problems can be solved. But knowledge is not the same thing as wisdom. Knowledge can produce equally powerful ways to destroy life, intentionally and unintentionally. It can produce hate and seek destruction. Knowledge does not by itself bring any answer to the ancient Greek question "What is a Good Life" It does not produce good sense, courage, generosity and tolerance. And most crucially, it does not produce the farsightedness that will allow us all to live together—and grow together—on this world without causing war, chaos and catastrophe. For that we need wisdom.
A suitable title for the passage would be ______.

A.
Knowledge and World Economy
B.
Diffusion of Science
C.
The Earth’s Learning Curve
D.
Knowledge and Wisdom

【单选题】The onset of a new generation of computer attacks was marked by () A. an organization of gangs B. the infection of PCs C. the sale of a software D. a website’s vanishing

A.
The "MyDoom" virus could presage a generation of computer attacks by organised gangs aiming to extract ransoms from online businesses, experts said yesterday.
B.
The warning came as the website run by SCO, a company that sells Unix computer software, in effect disappeared from the web under a blizzard of automated attacks from PCs infected by the virus, which first appeared a week ago.
C.
The "MyDoom-A" version of the virus is reckoned to be the worst to have hit the internet, in terms of the speed of its spread, with millions of PCs worldwide believed to be infected. Such "zombie" machines begin to send out hundreds of copies of the virus every hour to almost any e-mail address in their files.
D.
On Sunday they began sending automated queries to SCO’s website, an attack that will continue until 12 February. The attack is the web equivalent of ringing the company’s doorbell and running away a million times a second, leaving its computers unable to deal with standard requests to view its pages.
E.
"You have to wonder about the time limit," said Graham Cluley, senior technology consultant at the antivirus company Sophos. "Someone could go to SCO after the 12th and say, ’If you don’t want this to happen again, here are our demands’." Raimund Genes, European president of the security software firm Trend Micro, said: "Such a programme could take out any major website on the internet. It’s not terrorism, but it is somebody who is obviously upset with SCO"
F.
SCO has earned the enmity of computer users through a lawsuit it has filed against IBM. SCO claims ownership of computer code it says IBM put into the free operating system Linux, and is demanding licence fees and damages of $1bn.
G.
Mr. Cluley said: "It might be that whoever is behind this will say to SCO, ’if you don’t want the next one to target you, drop the lawsuit’." SCO has offered $250,000 (£140,000) for information leading to the arrest of the person or people who wrote and distributed MyDoom.
H.
Nell Barrett, of the security company Information Risk Management, said, "I would give a lot of credence to the idea of gangs using viruses to extort money. It’s hard for law enforcement to track them down, because they’re using machines owned by innocent people."
I.
A second variant of MyDoom will start attacking part of Microsoft’s website later today. The antivirus company MessageLabs said it had blocked more than 16 million copies of the virus in transit over the net so far. But millions more will have reached their targets.
