Keeping the Net Secure


On September 11 traditional telephone providers did a heroic job of struggling to restore service. When the World Trade Center towers fell, they severely damaged a Verizon central office with 350,000 voice lines and 3.5 million data circuits carrying the financial information that is the lifeblood of Wall Street firms. Verizon employees and those of many other telecommunications carders worked night and day, alongside the firemen, the police, and volunteers, at their own recovery job. In about a week they had rerouted some two million data circuits, restored switches, and installed temporary power supplies. The other 1.5 million circuits originated in buildings that no longer exist.
In the days after the attack the number of voice calls in the five boroughs of New York City doubled, from the normal 115 million a day to more than 230 million. For the next six days Verizon waived charges for its pay phones in Manhattan. On a single day following the disaster residents placed some 22,000 local calls free of charge from regular sidewalk pay phones below Canal Street, and Williams Communications switched five million voice calls in the metropolitan area-three times the average daily volume. AT&T's long-distance volume jumped from a weekday average of about 300 million domestic voice calls to more than 431 million on September 11, the busiest weekday ever across AT&T's domestic voice network.
But despite the efforts to keep them in operation, under the extraordinary pressure of September 11 the traditional voice-telecommunications systems in the New York area and the Washington, D.C. area--both wire and wireless--were significantly overtaxed. In East Coast cities cell-phone networks could not keep up with demand. Many long-distance calls inbound to New York City were blocked, in part to reserve circuits for outgoing calls. On that day the Internet proved its value as an essential part of the modem communications system.
More than half of America now uses the Internet. Globally, users number more than 300 million. Virtually all large businesses use the public Internet or private versions of the same technology to conduct their most important activities. So it was not surprising--although it was staggering--to see that on September 11 more than 1.2 billion instant messages were sent by AOL users alone. Slipping past the congested voice networks onto the PC screens of friends and family around the globe were the ties that bind us in the modem world: "R U OK?" "ALRIGHT? “ “U THERE?"
As voice networks blocked incoming calls to New York in order to relieve congestion, some carders pushed their voice traffic over the Internet. ITXC, which specializes in Internet voice services, saw its domestic wholesale business double on September 11 as carriers searched for new channels of communication; Yahoo's PC to Phone calling service increased by 59 percent. The performance of these voice-over-IP services suggests that in only a handful of years most voice traffic is likely to be carded on the Internet.
Why did the Internet work so well in the face of huge volume? Because its "distributed" technology is inherently robust. "Normal" phone connections, whether by means of wired line networks or by wireless cellular networks, open a specific circuit, or channel, connecting the person who is called and the caller. Just as if a superhighway lane were opened for one car only, the circuit remains dedicated to the conversation even if no one is speaking at the moment. If too many circuits are requested at one time, the system blocks calls.
In contrast, Internet messages don't travel on designated circuits. Instead, the messages are coded in is and Os, and then disassembled into packets of data. The packets go out from the PC down the phone line and into the maze of interconnected fibers that envelops every metropolitan area of every developed country in the world. Like cars on a superhighway, packets share lanes on the Net.
Each packet contains a destination address. As the packet moves into the maze, it encounters a router that selects the next step in the network. If the router senses congestion on one route, it selects another. The AOL instant-message packets could work their way around the jams and outage of the voice network and find their destinations in seconds.
One lesson from September 11 is that in order to maintain an effective communications system in the face of any calamity, we should promote and protect the Internet as a primary network, encouraging the private sector and using the resources of the public sector to make it faster, more robust, ubiquitous, and better integrated with other media. This policy would be consistent with the Internet's original development as an aspect of national security.
Not many creators of Internet technology or leaders of Internet companies have been seriously interested in world affairs. Indeed, only yesterday many people imagined, naively, that the rise of the medium meant the end of government, the triumph of libertarian visions, and the dawning of a new age of spontaneous self-organization. In the long run the Net's emphasis on liberty can be fused with the needs of a civil equitable, ordered state. But in the short run we need practical steps to help keep the Internet secure. The world's citizens, businesses, and governments should come together to take two actions.
First, Internet access should be made truly global. In less developed countries this means expanding communications systems so that more people have exposure to and access to information from the outside world. Obviously, communications technology does not by itself end conflict or convert nations to democracy. But it helps, and those goals are easier to reach with a modem communications system than without one. However our current war against terrorism ends, along the way the United States and its allies will undoubtedly make a variety of economic promises to the Central Asian states whose support we need. It would be better to direct aid toward thought-out goals than to grant it slapdash. A $ 10 billion investment fund for communications improvements throughout the developing world, managed by an independent board and funded half by private institutions and half by governments, would be a wise use of our resources.
In developed countries universal access means ensuring that businesses and citizens can all get high-speed connections to the Internet, much as they now have universal dial-tone access to the traditional telephone system. The United States has a long history of subsidizing the growth of a democratically available communications system. In keeping with the established universal service policy, business and suburban customers of telephone services are "overcharged" some $ 30 billion each year in order to subsidize basic telephone rates for rural customers. Diverting $ 10 billion of this universal-service funding could eventually make broadband service available on a near universal basis. Consumers could draw on a federal fund for whichever competing service they chose. The fund would pay a high proportion of the total cost for poor and rural users, a low one or none at all for rich users. Andy Grove, the chairman of Intel, recently called for a similar investment plan.
Second, the Internet's defenses need to be strengthened. The networks that compose its backbone should be encouraged with strong incentives to develop redundant interconnection points and diverse paths. The Internet's conceptual design makes it inherently resilient, but its physical structure and hardware need to be more secure than they are now. The one or two dozen essential crossroads of the Internet are basically collections of computers in buildings. These are vital nodes of our national security, and they ought to be as carefully protected as our military installations. The Internet has a rising number of co-location facilities where many fiber cables are aggregated. If any of them goes down, traffic can be interrupted for long periods. This became clear last summer in Baltimore, when a train derailment damaged a substantial fiber link and affected the flow of Internet traffic around the globe.
Every essential node should have a backup. Internet messages are now carried mainly on fiber-optic systems. These systems should be backed up by microwave and satellite-transmission systems.
The terrorists did not directly target our communications networks, but those networks are an integral part of the democratic capitalism that they did attack. And we can use those networks to help fight back.

第 10 题:Reading Comprehension (Reading in Depth):

A child who has once been pleased with a tale likes, as a rule, to have it retold in identically the same words, but this should not lead parents to treat printed fairy stories as sacred texts. It is always much better to tell a story than to read it out of a book and, if a parent can produce an improvement on the printed text, so much the better.
A charge made against fairy tales is that they harm the child by frightening him or arousing his sadistic impulses. To prove the latter, one would have to show in a controlled experiment that children who have read fairy stories were more often guilty of cruelty than those who had not. On the whole, their symbolic verbal discharge seems to be rather a safety valve than an incitement to overt action. As to fears, there are, I think, well-authenticated cases of children being dangerously terrified by some fairy story. Often, however, this arises from the child having been told the story on only one occasion. Familiarity with the story by repetition turns the pain of fear into the pleasure of a fear faced and mastered.
There are also people who object to fairy stories on the grounds that they are not objectively tree, that giants, witches, two-headed dragons, magic carpets, etc., do not exist; and that, instead of indulging his fantasies in fairy tales, the child should be taught how to adapt to reality by studying history and mechanics. I find such people, I must confess, so unsympathetic and peculiar that I do not know how to argue with them. If their cases were sound, the world should be full of madmen attempting to fly from New York to Philadelphia on a broomstick or covering a telephone with kisses in the belief that it was their enchanted girlfriend.
No fairy story ever claimed to be a description of the external world and no sane child has ever believed that it was.

1小题>

The author considers that a fairy story is more effective when it is ______ by the parents.

2小题>

If experiment proved that children who have read fairy stories were more often guilty of ______ cruelty than those who had not read such stories, it would mean that ______.

3小题>

From the passage, we learn that great fear can be stimulated in a child when a story is told ______ time(s).

4小题>

According to the passage, the advantage claimed for repeating fairy stories to young children is that it ______.

5小题>

Some others think children should study history and mechanics rather than reading fairy stories because they think ______.

第 11 题:Reading Comprehension:

The ownership of pets brings a variety of benefits that the uninitiated would never believe. For every tale of shredded cushion, flattened plants, chew slippers, there is another testimonial of intelligence, sympathy and undying devotion. Now the growing body of research into the medical and social advantages of pet ownership has confirmed what pet owners have always intuitively known: that pets are not just loving companions but actually do us good. Researchers have established the value of pets in soothing and reassuring humans, particularly when ill, lonely or in distress. Perhaps the unquestioning love and approval pets give us is something we don't always get from our human nearest and dearest.
Our makeshift understanding psychology leads many of us to view very close relationships with pets with suspicion. Childless couples in particular give rise to speculation, but a consultant in animal behavior says, "There is no evidence that a pet is a direct substitute for child." And while many adults feel foolish if caught talking to their pets, they have no need to. The experts say you cannot have' a close relationship with a pet without treating it as a person and that talking to a pet is not unhealthy--simply a way of establishing camaraderie.
The shaking helplessness of a young puppy or fluffy kitten stirs protective instincts deep within us and prompts many parents to buy pets for their children in the hope of instilling a sense of responsibility and caring and acceptance of the facts of life and death. Hut animals don't have to be soft and fond to bring out the best in us. A social worker encouraged aggressive boys to handle ferrets--if handled correctly they respond with friendship; if incorrectly they bite."
There seems to be no doubt that, emotionally and physically, our pets do us good--there is a price to be paid. When loved animal dies it is often a traumatic event--and then where do we turn for comfort?

1小题>

Pets are sometimes criticized because they ______.

A lack intelligence

B are destructive

C need considerable care

D demand affection

2小题>

The idea that animals are a substitute for children is ______.

A supported by research

B encouraged by psychologists

C an argument for keeping a pet

D a common prejudice

3小题>

Talking to animals is ______.

A silly

B suspicious

C beneficial

D stimulating

4小题>

A ferret is probably a kind of ______.

A tame animal

B fierce animal

C lovely animal

D tamable animal

5小题>

The writer believes that pets are valuable to children because they ______.

A return affection

B are comforting

C need looking after

D  are protective

第 12 题:Reading Comprehension:

Television has transformed politics in the United States by changing the way in which information is disseminated, by altering political campaigns, and by changing citizens' patterns of response to politics. By giving citizens independent access to the candidates, television diminished the role of the political party in the selection of the major party candidates. By centering politics on the person of the candidate, television accelerated the citizen's focus on character than issues.
Television has altered the forms of political communication as well. The messages on which most of us rely are briefer than they once were. The stump speech, a political speech given by traveling politicians and lasting 1.5 to 2 hours, which characterized nineteenth century political discourse, has given way to the 30-second advertisement and 10-second "sound bite (原声摘要)" in broadcast news. Increasingly the audience for speeches is not that standing in front of the politician but rather viewing audience who will hear and see a snippet (摘录) of the speech on the news.
In these abbreviated (缩减的)forms, much of what constituted the traditional political discourse of earlier ages has been lost. In 15 or 30 seconds, a speaker cannot establish the historical context that shaped the issue in question, cannot detail the probable causes of the problem, and cannot examine alternative proposals to argue that one is preferable to others. In snippets, politicians assert but do not argue.
Because television is an intimate medium, speaking through it required a changed political style that was more conversational, personal, and visual than that of the old-style stump speech. Reliance on television means that increasingly our political world contains memorable pictures rather than memorable words. Schools teach us to analyze words and print. However, in a world in which politics is increasingly visual, informed citizenship requires a new set of skills.
Recognizing the power of television's pictures, politicians craft televisual, staged events, called pseudo events, designed to attract media coverage. Much of the political activity we see on television news has been crafted by politicians, their speechwriters, and their public relations advisers for televised consumption bites in news and answers to questions in debates increasingly sound like advertisements.

1小题>

A politics in the United States has been significantly changed by television

B citizens in the United States prefer to see politicians on television instead of in person

C politics in the United States has become substantially more controversial since the introduction of television

A enjoy explaining the issues to broadcasters

B take stronger positions on issues than in the past

第 13 题:Cloze:

For many people today, reading is no longer relaxation.
