Obviously, there would be no point in investing in a computer if you had to check all its answers, but people should also rely on their own internal computers and check the machine when they have the feeling that something has gone wrong.
Questioning and routine double-checks must continue to be as much a part of good business as they were in pre-computer days. Maybe each computer should come with the warning: for all the help this computer may provide, it should not be seen as a substitute for fundamental thinking and reasoning skills.
第36题：What is the main purpose of this passage？
A) To look back to the early days of computers.
B) To explain what technical problems may occur with computers.
C) To discourage unnecessary investment in computers.
D) To warn against a mentally lazy attitude towards computers

While computers offer these conveniences to consumers, they have many advantages for sellers too. Electronic cash registers can do much more than simply ring up sales. They can keep a wide range of records, including who sold what, when, and to whom. This information allows businessmen to keep track of their list of goods by showing which items are being sold and how fast they are moving. Decisions to reorder or return goods to suppliers can then be made. At the same time these computers record which hours are the busiest and which employees are the most efficient, allowing personnel and staffing assignments to be made accordingly. And they also identify preferred customer for promotional campaigns. Computers are relied on by manufacturers for similar reasons. Computer analyzed marketing reports can help to decide which products to emphasize now, which to develop for the future, and which to drop. Computers keep track of goods in stock, of raw materials on hand, and even of the production process itself.
Numerous other commercial enterprises, from theaters to magazine publishers, from gas and electric utilities to milk processors, bring better and more efficient services to consumers through the use of computers.
According to the passage, the credit card enables its owner to ______.
A．withdraw as much money from the bank as he wishes
B．obtain more convenient services than ordinary people do
C．enjoy greater trust from the storekeeper
D．cash money where he wishes to

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!"

In the 1950s, the pioneers of artificial intelligence (AI) predicted that, by the end of this century, computers would be conversing with us at work and robots would be performing our housework. But as useful as computers are, they're nowhere close to achieving remotely resembling these early aspirations for humanlike behavior. Never mind something as complex as conversation: the most powerful computers struggle to reliably recognize the shape of an object, the most elementary of a ten-month-old kid. A growing group of AI researchers think they know where the field went wrong.
The problem, the scientists say, is that AI has been trying to separate the highest, most abstract levels of thought, like language and mathematics, and to duplicate them with logical, step-by-step programs. A new movement in AI, on the other hand, takes a closer look at the more roundabout way in which nature came up with intelligence. Many of these researchers study evolution and natural adaptation instead of formal logic and conventional computer programs. Rather than digital computers and transistors, some want to work with brain cells and proteins. The results of these early efforts are as promising as they are peculiar, and the new nature-based Al movement is slowly but surely moving to the forefront of the field.
Imitating the brain's neural network is a huge step in the right direction, says computer Scientist and biophysicist Michael Conrad, but it still misses an important aspect of natural intelligence. "People tend to treat the brain as if it were made up of color-coded transistors", he explains." But it's not simply a clever network of switches. There are lots of important things going on inside the brain cells themselves." Specifically, Conrad believes that many of the brain's capabilities stem from the pattern-recognition proficiency of the individual molecules that make up each brain cell. The best way to build an artificially intelligent device, he claims, would be to build it around the same sort of molecular skills.
Right now, the notion that conventional computers and software are fundamentally incapable of matching the processes that take place in the brain remains controversial. But if it proves true, then the efforts of Conrad and his fellow AI rebels could turn out to be the only game in town.
The author says that the powerful computers of today ______.
A．are capable of reliably recognizing the shape of an object
B．are close to exhibiting humanlike behavior
C．are not very different in their performance from those of the 50's
D．still cannot communicate with people in a human language

Some of the computer experiments now going on inspire exciting visions of the future. For example, scientists are working on devices that can electronically perform. some sight and hearing functions, which could make life easier for the blind and deaf. They're also working on artificial arms and legs that respond to the electric impulses produced by the human brain. Scientists hope that some day a person who's lost an arm could still have near-normal brain control over an artificial arm.
Video games, computerized special effects in movies, and real-life training machines now being used by the US Army are causing some people to predict new educational uses for computers. Computers could some day be used to simulate travel to other planets, to explore the ocean floor, or to look inside an atom.
Experiments with electronic banking and shopping inspire predictions that these activities will soon be done from home computer terminals. Cars, too, might be equipped with computers to help drivers find their way around (Honda has one in an experimental car) or to communicate with home and office computers. Many people, including handicapped workers with limited ability to move around, already are working at home using computer terminals. Each terminal is connected to a system at a company's main office. Some futurists say the day may come when few people will have to leave home to go to work -- they'll just turn on a terminal
A growing number of factories such as the General Motors Plant in Newark, Delaware, "hire" computerized robots to perform. tasks such as spot welding. Some executives get a gleam in their eyes as they envision the spread of these "perfect workers" -- no coffee breaks, no strikes, and no vacations or sick days.
These modern and potential computer uses are possible because of the silicon microchip.
These chips, which have become increasingly complex since their beginning in 1959, contain a network of information pathways. Electronic impulses travel along the paths. The plans for a chip look much like a city street plan and can be as large as a football field. It can take as long as three months to complete a new chip design. Chips are used to store information, too. An entire "computer" can be put onto one chip -- called a microprocessor.
As chips become even more complex, easier to make, and less costly, futurists predict limitless possibilities. A group of Japanese scientists is working on a new generation of computers, which they hope will be able to understand vocal instructions, talk back to their users, and automatically try out alternate solutions to a problem to come up with the best answer.
Some people say that the humans of the future will never be without their companion -- computers. Predicting the future can be tricky, of course. In 1948 an IBM study predicted that there would never be enough demand for computers to justify going into the business!
What is the purpose of the passage？
A．To tell the readers what computers will look like in the future.
B．To show the close relations between man and computers.
C．To tell the readers how important silicon microchips are.
D．To talk about the possible future uses of computers.
