In what now seems like the prehistoric times of computer history, the early postwar era(战后时期), there was a quite widespread concern that computers would take over the world from man one day. Already today, less than forty years later, as computers are relieving us of more and more of the routine tasks in business and in our personal lives, we are facing with a less dramatic but also less foreseen problem. People tend to be over trusting (过分信任) of computers and are reluctant to challenge their authority. Indeed, they behave as if they were hardly aware that wrong buttons maybe pushed, or that a computer may simply malfunction(失灵).
Obviously, there would be no point in investing(投入) 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 following warning: for all the help this computer may provide, it should not be seen as a substitute for fundamental thinking and reasoning skills.

A.To look back to the early days of computers
B.To explain what technical problems may occur with computers

But, you know, it is very possible that in the future the question will disappear, and we might very well ask instead, "What do you play？"
Computers and other technological, equipment are making jobs more automated and less personally demanding. Scientists tell us that one day in the foreseeable future, very few people will have to work. Our society will be operated by computers and we will have much more free time, so that our games will become more important than our jobs.
At the beginning of this century, almost everybody believed in work. But by the end of this century, we might be thinking quite differently. Today, people are divided into social classes in accordance with the types of work they do; tomorrow, it is more than likely that we will be divided according to the types of games we play.
This change in the use of our time may give rise to a new race of therapists (治疗学家) called "fun specialists," who will fill the same functions as our current career specialists. They will show us how to get the most fun and enjoyment out of our leisure time. Someday people will no longer be known primarily by the work they do.
What is the main idea of the passage？
A．Work plays an important part in our general lifestyle.
B．People are divided into social classes according to how much they earn each month.
C．It is very possible that game will replace work as the most important part in our life.
D．Game players know how to get the most fun and enjoyment out of our leisure time.

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 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.

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 anything 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 tasks for 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 AI 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 option 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
