单选题 More and more, the operations of our businesses, governments, and financial institutions are controlled by information that exists only inside computer memories. Anyone clever enough to modify this information for his purpose can get in substantial rewards. Even worse, a number of people who have done this and been caught at it have managed to get away without punishment. It's easy for computer crimes to go undetected if no one checks up on what the computer is doing. But even if the crime is detected, the criminal may walk away not only unpunished but with a growing recommendation from his former employers. Of course, we have no statistics on crime that go undetected. But it is disturbing to note how many of the crimes we do know about were detected by accident, not by systematic inspection or other security procedures. The computer criminals who have been caught may be the victims of uncommonly bad luck. For example, a certain keypunch (打孔机) operator complained of having to stay overtime to punch extra cards. Investigation revealed that the extra cards she was being asked to punch were for dishonest transactions. In another case, dissatisfied employees of the thief tipped off the company that was being robbed. Unlike other lawbreakers, who must leave the country, commit suicide, or go to jail, computer criminals sometimes escape punishment demanding not only that they not be charged but that they be given good recommendations or perhaps other benefits. All too often, their demands have been met. Why? Bemuse company executives are afraid of the bad publicity that would result if the public found out that their computer had been misused. They hesitate at the thought of a criminal boasting in open court of how he secretly manipulate the most confidential records right under the noses of the company's executives, accountants and security staff. And so another computer criminal depart with just the recommendations he needs to continue his crimes elsewhere.

单选题People"s tastes in recreation differ widely. At a recent festival of pop-music in the Isle of Wight, crowds of teenagers flocked to listen to their favorite singers and musicians. They went with single railway tickets and slept in the open, a very risky thing to do in the climate of Britain, even in August. They were packed together like sardines for four days. There were innumerable thieves, a gang of roughs tried several times to break things up, and police were everywhere. At the end of the festival many young fans found themselves broke, with no money left, and they had difficulty in getting back home. Most people would consider these conditions a nightmare of discomfort; the fans appeared to enjoy it all enormously. Even in the overcrowded United Kingdom there are large tracts of open un-spoilt country, where people with more traditional tastes can go for quiet, and for the sense of freedom they derive from contact with nature. In the national parks especially, modem development of housing and industry is strictly controlled. Visitors may walk for miles through landscape of the greatest beauty and wildness, and often of considerable historic or scientific interest. Along the coasts of some of the maritime counties, public pathways have been created; these paths stretch for many miles along cliffs that look out on the Atlantic Ocean or the English Channel. Another path, lying inland, goes along the range of mountains in the north of England. It is called the Pennine Way. Here, the long-distance walker and the nature-lover can find much to enjoy, without feeling disturbed by large numbers of their fellows. Yet few people make full use of the national parks established for everyone"s benefit. The commonest thing nowadays is for family groups to motor out to a beautiful spot and park their cars in a lay-by (英国的路旁停车带). A picnic basket is produced, along with a folding table and chairs, a kettle and a portable stove. They then settle down to a picnic in the lay-by beside the car. Apparently their idea of enjoyment is to get into the fresh air and amongst the country sights and sounds without having to walk a yard. They seem almost to like to hear and to smell the traffic.
