Computers in Cars

You&39;re far from home on alonely road. Shadowy forests stretch away on both sides. athickmist (雾) makes it difficult to see far beyond your car&39;s windshield (挡风玻璃).

"Can this B．e route 90A？" you wonder. If it is, you should be near atown. Yet there&39;s nohint of one. Night is closing in. And you&39;re low on gasoline.

This is asituation where an in-car computer that can navigate would be abig help.

A car computer that navigates？ Yes! Such computers exist. Several experimental models arebeing tested by General Motors, Ford, Chrysler, and several foreign car makers. These computersvary in detail. but they all contain series of maps on videodiscs or videotapes. For example, onecomputer system contains 13,300 maps covering the continental US.

before starting out on atrip, A．driver can type in the code for the region he or she plans todrive through. The computer then shows amap of that region. At the same time, atiny radio re-ceiver linked to the computer goes to work. It picks up signals from navigation satellites such asthe NAVSTAR network. Using these signals, the computer shows the car&39;s position at all timesand displays this position on the map. The computer can also calculate and display the best routeto follow.

Anavigation computer may also receive and use dataabout road construction, weather condi-tions, and trafficjams. This information would be displayed to the driver and the computer wouldalso use the information to work out alternate (交替的 ) routes.

Most cars nowadays also contain computers that help cars run more efficiently. Microproces-sors (微处理的) control certain engine functions B．y regulating the mixing of fuel. Dataon carspeed, oil pressure, revolutions per minute, engine temperature, and fuel level can be displayedas digital data(numbers) or warning lights.

Some auto designers suggest that acentral computer display be used to clearly present suchtimely information as car speed and fuel level. Warning lights would indicate adrop in oil pres-sure or asudden rise in engine temperature. To get more information on these conditions, thedriver could call it up on the computer display screen. When needed, the computer could be"asked" to provide navigation aid or information about the car&39;s condition.

by describing atypical situation of alost driver on the road， the author intends to__________. 查看材料

A.make us believe how complex the highway computer network is

B.let us know how in-car computers are linked to road signs

C.show us how helpful anavigation computer can be

D.tell us that NAVSTAR has come into use

阅读材料，回答题。

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.

What is the main purpose of this passage？ 查看材料

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 the blindness to the probable shortcomings of computers

阅读材料，回答题。

Much unfriendly feeling towards computers has been based on the fear of widespread unemployment resulting from their introduction. Computers are often used as part of automated(自动化的) production systems requiring a least possible number of operators, causing the loss of many jobs. This has happened, for example, in many steelworks.

On the other hand, computers do create jobs. They are more skilled and better paid, though fewer in number than those they replace. Many activities could not continue in their present form. without computers, no matter how many people are employed. Examples are the check clearing (交换) system of major banks and the weather forecasting system.

When a form. introduces computers, a few people are usually employed in key posts (such as jobs of operations managers) while other staff are w-trained as operators, programmers, and data preparation staff. After the new system has settled down, people in non-computer jobs are not always replaced when they leave, resulting in a decrease in the number of employees. This decrease is sometimes balanced by a substantial increase in the activity of the frim, resulting from the introduction of computers.

The attitudes of workers towards computers vary. There is fear of widespread unemployment and of the takeover of many jobs by computer-trained workers, making promotion for older workers not skilled in computers more difficult.

On the other hand, many workers regard the trend toward wider use of computers inevitable.They realize that computers bring about greater efficiency and productivity, which will improve the condition of the whole economy, and lead to the creation of more jobs. This view was supported by the former British Prime Minister, James Callaghan in 1954, when he made the point that new technologies hold the key to increased productivity, which will benefit the economy in the long ran.

The unfriendly feeling towards computers is developed from 查看材料

A.the possible widespread unemployment caused by their introduction

B.their use as part of automated production systems

C.the least possible number of operators

D.the production system in steelworks

Why Would They Falsely Confess？

Why on earth would an innocent person falsely confess to committing a crime？ To most people, it justdoesn&39;t seem logical. But it is logical, say experts, if you understand what could happen in a police interrogation(审讯) room. Under the right conditions, people&39;s minds are susceptible (易受影响的 ) to influence, and the pressure put on suspects during police grilling (盘问 ) is enormous.

46"The pressure is important to understand because otherwise it&39;s impossible to understand why someone would say he did something he didn&39;t do. The answer is to put an end to an uncomfortable situation that will continue until he does confess." Developmental psychologist Allison Redlich recently conducted a laboratory determine how likely people are to confess to things they didn&39;t do.47The researchers then intentionally crashed the computers and accused the participants of hitting the "alt" key to see if they would sign a statement falsely taking responsibility.

Redlich&39;s findings clearly demonstrate how easy it can be to get people to falsely confess: 59 percent of the young adults in the experiment immediately confessed.48Of the 15 to 16-year-olds, 72 percent signed confessions, as did 78 percent of the 12 to 13-year-olds.

"There&39;s no question that young people are more at risk, " says Saul Kassin, Professor at Williams College, who has done similar studies with similar results.49A psychology Both Kassin and Redlich note that the entire "interrogation" in their experiments consisted of a simple accusation-not hours of aggressive questioning-and still, most participants falsely confessed.

Because of the stress of a police interrogation, they conclude, suspects can become convinced that falsely confessing is the easiest way out of a bad situation.50

请在第__（46）__处填上正确答案。 查看材料

A.In her experiment participants were seated at computers and told not to hit the "Alt" key， because doing so would crash the systems.

B.In some ways，" says Kassin， " false confession becomes a rational decision."

C."It"s a little like somebody"s working on them with a dental （牙齿的 ） drill， " says Franklin Zimring， a law professor at the University of California at Berkeley.

D."But adults are highly vulnerable too."

E.How could an innocent person admit to doing something he didn"t do？

F.Redlich also found that the younger the participant， the more likely a false confession.

阅读下文，回答题

It is difficult to imagine what life would be like without memory. (78) The meanings of thou-sands of everyday perceptions . the bases for the decisions we make, and the roots of our habits and skills are to be found in our past experiences, which are brought into the present by memory.

Memory can be defined as the capacity to keep information available for later use. It includes not only "remembering" things like arithmetic or historical facts, but also involving any change in the way an animal typically behaves. (79) Memory is involved when a rat gives up eating grain be-cause he has sniffed something suspicious in the grain pile. Memory is also involved when a six-year-old child learns to swing a baseball bat.

Memory exists not only in humans and animals but also in some physical objects and ma-chines. Computers, for example, contain devices for storing data for later use. It is interesting to compare the memory-storage capacity of a computer with that of a human being. The instant-access memory of a large computer may hold up to 100,000 "words"--ready for instant use. An averageU.S. teenager probably recognizes the meaning of about 100,000 words of Engfish. However, this is but a fraction of the total amount of information which the teenager has stored. Consider, for ex- ample, the number of faces and places that the teenager can recognize on sight.

The use of words is the basis of the advanced problem-solving intelligence of human beings.

A large part of a person' s memory is in terms of words and combinations of words.

According to the passage， memory is considered to be__________. 查看材料

A.the basis for decision making and problem solving

B.an ability to store experiences for future use

C.an intelligence typically possessed by human beings

D.the data mainly consisting of words and combinations of words
