In only a short time, computers have【B8】changed the way in which many kinds of work are done.【B9】, they have created whole new areas of work that did not exist【B10】to their development. We have all heard of computers【B11】the course of rockets, preparing bank statements,【B12】elections, forecasting weather, and so【B13】Computers do many tasks for us that would be【B14】difficult if we did not have them. Computers take routine tasks and do them in a【B15】of the time it would take a man or even a【B16】of men to do them.
Many people imagine that a computer is a very large【B17】machine. Certainly a computer can function in that way,【B18】this is a very restricted view of the nature of a computer. The message of a familiar【B19】is that machines should work, but men should think. This is the basic philosophy of computer science,【B20】in the advanced states of computer technology.

The computer lovers talk about how useful computers can be in business, in education and in the home—apart from all the games, you can do your accounts on them, use them to control your central heating, and in some places even do your shopping with them. Computers, they say, will also bring some leisure, as more and more unpleasant jobs are taken over by computerized robots.
The haters, on the other hand, argue that computers bring not leisure but unemployment. They worry, too, that people who spend all their time talking to computers will forget how to talk to each other. And anyway, they ask, what's wrong with going shopping and learning languages in a classroom with real teachers？ But their biggest fear is that computers may eventually take over from human beings altogether.
What does this passage mainly talk about？
A．Computers have become part of our daily lives.
B．Computers have advantages as well as disadvantages.
C．People have different attitudes to computers.
D．More and more families will own computers.
Does this sound familiar？ You have probably read something like it in magazines or books, or seen it in a film. Why is it so popular？ One of the reasons is that it reflects the fears of many people; fear of the unknown fear of what is not understood or, at least, fear of something that is not completely understood.
The fact is that every day it seems that computers take control of another area of our lives. Some
factory jobs are now done by robots and the robots are controlled by computers. Our bank accounts are managed by computers. At the airport, our tickets are sold by a computer. Certainly, many of these operations are made more
efficient by computers, but our admiration is sometimes mixed with unsafe feelings. And this lack of safety is caused by the fact that we do not know how computers do these things, and we really don't know what they might do next. But we can find out how computers work, and once we understand them, we can use computers instead of worrying about being used by them. Today, there is a new generation of computer wizards who know exactly how computers get things done. These young men and women, usually university students, are happy to sit for hours, sometimes for days, designing programs, not eating, not sleeping, but discovering what can be done by these wonderful slaves which they have learned to control. These computer wizards have learned to use the computer and search for new tasks for their machines.

Computers Concern You
When Charles Babbage, a professor of mathematics at Cambridge University, invented the first calculating machine in 1812 he could hardly have imagined the situation we find ourselves in today. Nearly everything we do in the modern world is helped, or even controlled, by computers, the complicated descendants of his simple machine. Computers are being used more and more extensively in the world today, for the simple reason that they are far more efficient than human beings. They have much better memories and can store huge amounts of information, and they can do calculations in a fraction of the time taken by a human mathematician. No man alive can do 500,000 sums in one second, but an advanced computer can. In fact, computers can do many of the things we do, but faster and better. They can pay wages, reserve seats on planes, control machines in factories, work out tomorrow's weather, and even play chess, write poetry, or compose music. Let's look now at some of the ways in which computers concern people in their daily lives and work.
Computers and our Cash
Mr. Woods, a bank manager, discussed some of the ways in which computers control our cash. "I think most of our customers realize that in modern banking we make extensive use of computers. They see that the codes on their cheques are printed in a special way so that they can be read by a computer-computers only seem to like rather square figures. And when they call in at the bank to find out the balance of their accounts, the clerk no longer shows them a big book with band-written entries. Instead he goes and gets a print-out from the computer which records all the details of cash or cheques paid into or drawn out of customers' accounts. The day may soon come when we no longer need to carry cash around with us, or even a cheque book. The computer where we work will tell our bank computer how much our salary or wages are—and the government computer how much tax we should pay! Then when we go shopping we will just show a special card at the check-out point. The code on the card will be fed into the shop computer, which will check with the bank computer that there is enough money in our account to pay for the goods we want, and that the card has not been stolen. If all is well, the codes from the different items will be fed into the computer and the sum owing will be drawn from our account, but only 'on computer'. No money will ever change hands. Computerized shopping, like computerized banking, will be quick, safe and convenient."
Computers and our Health
Nurse Penny Atkins works in a large, modern hospital.
"We use computers a lot in medicine nowadays. For instance, at the hospital where I work we make patients' appointments through a computer, which saves a lot of time. So does keeping patients' records on a computer. It also saves space because you can get so much more information on to a piece of computer tape than a piece of paper. Another advantage is that anyone who wants information on a patient can get it quickly, or even at the same time as someone else.
You just dial the computer. In the past a doctor might take a patient's records away to his room and keep them for weeks, which could make things difficult for the rest of us! Actually, computers can often do a doctor's work better than a human being can. Computers don't suffer from lack of sleep, so they don't miss important points. And because they never forget anything they've ever been told they're often better at working out what's wrong with a patient, or the best treatment to give him. Some people even think we should all have regular computer checks on our health and then we would ha able to cure most diseases in the early stages. We'd all spend less time in hospital, so the future would be better for us overworked nurses!"

A．Y
B．N
C．NG
听力原文： For good or bad, computers are now part of our daily lives. With the price of a small home computer now being lower, experts predict that before long all schools and businesses and most families in the rich parts of the world will own a computer of some kind. Among the general public, computers amuse strong feelings--people either love them or hate them.
The computer lovers talk about how useful computers can rein business, in education and in the home--apart from all the games, you can do your accounts on them, use them to control your control heating, and in some places even do your shopping with them. Computers, they say, will also bring some leisure, as more and more unpleasant jobs are taken over by computerized robots.
The haters, on the other hand, argue that computers bring not leisure but unemployment. They worry, too, that people who spend all their time talking to computers will forget how to talk to each other. And anyway, they ask, what's wrong with going shopping and learning languages in classroom with real teachers？ But their biggest fear is that computers may eventually take over human, beings altogether.
