  Until recently the chances for criminal activity(犯罪活动)on the Internet have been low.However, business done on the Internet is growing rapidly, as people order books and other products and make money transactions(交易).All this is a strong temptation(诱惑)for hackers.

  Hackers are often young people who are deeply attractedby computers.They use them to prowl the Internet, looking for ways to break into computer systems(系统)run by banks, telephone companies and even government departments.They look for examples of credit cards(信用卡)and try to steal the numbers.

  Recently in America, hackers have been caught testing the security(安全)system at the Pentagon, headquarter(总部)of the American Defence Department.But still the backers insist often for a dare “because it’s there” although with what success nobody really knows.

  Hackers seldom admit to(享有)a successful break in.The first sign of a security breach(泄密)may be when a customer discovers fraudulent(欺骗)money transaction on a credit card account(账户), and it is hard to discover it.

  “You just don’t give your credit card out to anybody, ”says Michael White, multimedia product manager for clear communications, “and in the same way you should regularly change your credit card entering number, you can defeat hackers by regularly changing your Internet password(密码).If you don’t, it’s like leaving the bank vault(金库)door wide open.”

  The warning against hackers is out there, and the answer is obviously to choose tricky passwords and change them frequently and to watch who you pass your credit card details to.

In the computer age, most of us take a broadband(宽带)Internet connection for granted. Whether cable or mobile broadband, today’s connections are many times faster than those in the early days. Videos play smoothly, complex websites load quickly, and files download much faster than ten years ago. And the files are much bigger too.
There’s a catch, of course: You have to live near enough to a major city to get broadband Internet. If you don’t, it’s slow dial-up access for you. And for those living really far out, there may be no Internet access at all.
Technology experts often talk about the “last mile” problem, which refers to the difficulty of bringing Internet access to remote locations. In cities and suburbs, it’s relatively easy to provide access for everyone. It is much more difficult to deliver access to those living far from cities, especially in developing countries. Internet service providers, for their part, have been reluctant to provide access to sparsely (稀疏地) populated areas. The handful of Internet users they would reach wouldn’t cover the expense.
But every year, technological advancements allow of more and more Internet users. Most broadband connections today run over existing cable TV and telephone lines although these technologies aren’t available everywhere.
Some companies have delivered the Internet over standard power lines. Advancements in cheaper, more efficient fiber optics cables (光纤电缆) promise to bring extremely fast Internet connections to more users.
Still, the “last mile” problem remains hard to deal with. There will always be somewhere that doesn’t have an affordable broadband connection. But someday that might not matter. If the rapid progress in cell phone technology is any indication (迹象), it may not be too long before an Internet connection simply follows you wherever you go.
【小题1】The underlined part “a catch” (in Paragraph 2) probably means “_____”.

A.a rare challengeB.a desirable planC.an efficient deviceD.a hidden problem
【小题2】What can we know from the third paragraph?
A.Internet connection has not been popular in most cities.
B.Internet service providers care about rural(农村的)customers.
C.Computer is popular in developing countries.
D.It is hard to bring Internet access to users in remote areas.
【小题3】Paragraph 4 mainly tells us that technological advancements _____.
A.make TV and telephone available everywhere
B.bring great change to people’s everyday life
C.make it possible for more people to use the Internet
D.bring faster Internet connections to users
【小题4】What may eventually settle the “last mile” problem?
A.The broadband connection’s getting faster.
B.More and more Internet users.
C.more and more Internet connections.
D.The rapid progress in cell phone technology.

When you think of the tremendous technological progress we have made, it’s amazing how little we have developed in other respects. We may speak scornfully of the poor old Romans because they enjoyed the seemingly excited killing that went on in their arenas(竞技场). We may despise them because they mistook these goings on for entertainment. We may forgive them because they lived 2000 years ago and obviously knew no better. But are our feelings of superiority(优越)really justified? Are we any less blood-thirsty? Why do boxing matches, for instance, attract such universal interest? Don’t the audience who attend them hope they will see some violence? Human beings remain as bloodthirsty as ever they were. The only difference between ourselves and the Romans is that while they were honest enough to admit that they enjoyed watching hungry lions tearing people apart and eating them alive, we find all sorts of arguments to defend sports which should have been banned long ago.

  It really is incredible that in this day and age we should still allow hunting or bull-fighting, that we should be prepared to sit back and watch two men punch each other in a boxing ring, that we should be relatively unmoved by the sight of one or a number of racing cars crashing and bursting into flames. Any talk of ‘the sporting spirit’ is merely hypocrisy(虚伪). People take part in violent sports because of the high rewards they bring. Audience are willing to pay vast sums of money to see violence. A world heavyweight championship match, for instance, is front page news. Millions of people are disappointed if a big fight is over in two rounds instead of fifteen. They feel disappointment because they haven’t experienced the exquisite pleasure of witnessing continuous violence.

  Why should we ban violent sports if people enjoy them so much? You may well ask. The answer is simple: they are uncivilized. For centuries man has been trying to improve himself spiritually and emotionally—though with little success. But at least we no longer tolerate the sight madmen imprisoned in cages, or public punishment of any of the countless other barbarous (野蛮的) practices which were common in the past. Prisons are no longer the harsh forbidding places they used to be. Social welfare systems are in operation in many parts of the world. Big efforts are being made to distribute wealth fairly. These changes have come about not because human beings have suddenly improved, but because positive steps were taken to change the law. The law is the biggest instrument of social change that we have and it may exert great civilizing influence. If we banned dangerous and violent sports, we would be moving one step further to improving mankind. We would recognize that violence is unworthy of human beings.
