根据材料，回答题。

Computers in Cars

You"re far from home on a lonely mad. Shadowy forests stretch away on both sides. A thick mist（雾） makes it difficult to see far beyond your car"s windshield （挡风玻璃）.

"Can this be route 90A？" you wonder. If it is， you should be near a town. Yet there"s no hint of one. Night is closing in. And you"re low on gasoline.

This is a situation where an in-car computer that can navigate would be a big help.

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

Before starting out on a trip， a driver can type in the code for the region he or she plans to drive through. The computer then shows a map of that region. At the same time， a tiny radio receiver linked to the computer goes to work. It picks up signals from navigation satellites such as the NAVSTAR network. Using these signals， the computer shows the car"s position at all times and displays this position on the map. The computer can also calculate and display the best route to follow.

A navigation computer may also receive and use data about road construction， weather conditions， and traffic jams. This information would be displayed to the driver and the computer would also use the information to work out alternate （交替的）routes。

Most cars nowadays also contain computers that help cars run more efficiently. Microprocessors （微处理机） control certain engine functions by regulating the mixing of fuel. Data on car speed， oil pressure， revolutions per minute， engine temperature， and fuel level can be displayed as digital data （numbers） or warning lights.

Some auto designers suggest that a central computer display be used to clearly present such timely information as car speed and fuel level. Warning lights would indicate a drop in oil pressure or a sudden rise in engine temperature. To get more information on these conditions， the driver 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"s condition.

By describing a typical situation of a lost 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 a navigation computer can be

D.tell us that NAVSTAR has come into use

The Difference between Man and Computer

What makes people different from computer programs？ What is the missing element that our theories don&39;t yet __________ (51) for？ The answer is simple: People read newspaper stories for a reason: to learn more about __________ (52) they are interested in. Computers, on the other hand,don&39;t. In fact, computers don&39;t __________ (53) have interests; there is nothing in particular that they are trying to fred out when they read. If a computer __________ (54) is to be a model of story understanding, it should also read for a "purpose".＜br＞

Of course, people have several goals that do not make __________ (55) to attribute to computers. One might read a restaurant guide __________ (56) order to satisfy hunger or entertainment goals, or to __________ (57) a good place to go for a business lunch. Computers do not get hungry, and computers do not have business lunches.＜br＞

However, these physiological and social goals give __________(58) to several intellectual or cognitive goals. A goal to satisfy hunger gives rise to goals to fmd __________ (59) about the name of a restaurant which __________ (60) the desired type of food, how expensive the restaurant is, the location of the restaurant, etc. These are goals to __________ (61) information or knowledge, what we are calling __________ (62) goals. These goals can be held by computers too; a computer__________ (63) "want" to find out the location of a restaurant, and read a guide in order to do so__________ (64) the same way as a person might. While such a goal would not __________(65) out of hunger in the case of the computer, it might well arise out of the "goal" to learn more about restaurants

请根据短文的内容，回答题。

Gender Gap

The girls in this sixth grade class in East Palo Alto, California, all have the same access to computers as boys. But researchers say, by the time they get to high school, they are victims of what the researchers call a major new gender (性别) gap in technology. Janice Weinman of the American Association of University Women says, "Girls tend to be less comfortable than boys with the computer. They use it more for word processing rather than for problem solving, rather than to discover new ways in which to understand information."＜br＞

After re-examining a thousand studies, the American Association of University Women researchers found that girls make up only a small percentage of students in computer science classes. Girls consistently rate themselves significantly lower than boys in their ability and confidence in using computers. And they use computers less often than boys outside the classroom.＜br＞

An instructor of a computer lab says he&39;s already noticed some differences. Charles Cheadle of Cesar Chavez School says, "Boys are not so afraid they might do something that will harm the computer, whereas girls are afraid they might break it somehow."＜br＞

Six years ago, the software company Purple Moon noticed that girls&39; computer usage was falling behind boys. Karen Gould says, "The number one reason girls told us they don&39;t like computer games is not that they&39;re too violent, or too competitive. Girls just said they&39;re incredibly boring."＜br＞

Purple Moon says it found what girls want, characters they can relate to and story lines relative to what&39;s going on in their own lives. Karen Gould of Purple Moon Software says, "What we definitely found from girls is that there is no intrinsic (固有的 ) reason why they wouldn&39;t want to play on a computer; it was just a content thing."＜br＞

The sponsor of the study says it all boils down to this: the technology gender gap that separates the girls from the boys must be closed if women are to compete effectively with men in the 21 st century.

According to the passage， girls are victims of the gender gap in technology because__________. 查看材料

A.they can not discover new ways to use computers

B.they have the same access to computers as boys

C.they are likely to be less comfortable with computers

D.they can only use computers for word processing

请根据短文内容，回答题。

New Research Lights the Way to Super-fast Computers

(1) New research published today in the journal Nature Communications, has demonstrated how glass can be manipulated to create a material that will allow computers to transfer information using light. This development could significantly increase computer processing speeds and power in the future.＜br＞

(2)The research by the University of Surrey, in collaboration with the University of Cambridge and the University of Southampton, has found it is possible to change the electronic properties of amorphous chalcogenides, a glass material integral to data technologies such as CDs and DVDs.＜br＞

By using a technique called ion doping, the team of researchers have discovered a material that could use light to bring together different computing functions into one component, leading to all-optical systems.＜br＞

(3)Computers currently use electrons to transfer information and process applications. On the other hand, data sources such as the Internet rely on optical systems; the transfer of information using light. Optical fibers are used to send information around the world at the speed of light, but these signals then have to be converted to electrical signals once they reach a computer, causing a significant slowdown in processing.＜br＞

(4) "The challenge is to find a single material that can effectively use and control light to carry information arotmd a computer. Much like how the web uses light to deliver information, we want to use light to both deliver and process computer data," said project leader, Dr Richard Curry of the University of Surrey.＜br＞

(5) "This has eluded researchers for decades, but now we have now shown how a widely used glass can be manipulated to conduct negative electrons, as well as positive charges, creating what are known as &39;pn-junction&39; devices. This should enable the material to act as a light source, a light guide and a light detector -- something that can carry and interpret optical information. In doing so, this could transform. the computers of tomorrow, allowing them to effectively process information at much faster speeds."＜br＞

(6) The researchers expect that the results of this research will be integrated into computers within ten years. In the short term, the glass is already being developed and used in next-generation computer memory technology known as CRAM, which may ultimately be integrated with the advances reported.＜

Why Would They Falsely Confess？

Why on earth would an innocent person falsely confess to committing a crime？ To mostpeople， it just doesn"t seem logical. But it is logical， say experts， if you understand what can happen in a police interrogation （审讯） room. Under the right conditions， people"s minds are susceptible （易受影响的） to influence， and the pressure put on suspects during police grillings（盘问） is enormous. __________ （46） "Thepressure is important to understand. Because，otherwise， it"s impossible to understand whysomeone would say he did something he didn"t do.

The answer is: to put an end to anuncomfortable situation that will continue until he does confess." Developmental psychologist Allison Redlich recently conducted a laboratorydetermine how likely people are to confess to things they didn"t do. __________ （47） The researchers then intentionally crashed the computers and accused the participants of hittingthe "alt" key to see if they would sign a statement falsely taking responsibility.

Redlich"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 __________ （48） Of the 15-to-16-year-olds， 72 percent signed confessions， as did 78 percent of the 12-to-13-year-olds.

"There"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. __________ （49） 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 becomeconvinced that falsely confessing is the easiest way out of a bad situation. __________ （50）

Electronic Mail

During the past few years，scientists all over the world have suddenly found themselves productively engaged in task they once spent their lives hvoiding——writing，any kind of writing，but particularly letter writing.Encouraged by electronic mail’s surprisingly high speed，convenience and economy，people who never before touched the stuff are regularly，skillfully，even cheerfullv tapping out a great deal of correspondence.

Electronic networks，woven into the fabric of scientific communication these davs. are the route to colleagues in distant countries，shared data，bulletin boards and electronic Joumals.Anyone with a personal computer， a modern and the software to link computers over teleDhone lines can sign on？An estimated five million scientists have done SO with more joining every day，most of them communicating through a bundle of interconnected domestic and foreign routes known collectively as the Internet，or net.

E-mail is starting to edge out the fax，the telephone，overnight mail，and of course.1and mail. It shrinks time and distance between scientific collaborators，in part because it is conveniently asynchronous（异步的）（Writers can type while their colleagues acmss time zones sleep;their message will be waiting.）.If it is not yet speeding discoveries，it is certainly accelerating communication.

Jeremy Bernstein，the physicist and science writer，once called E-mail the Dhysicist，s umbilical cord（脐带）.Later other people，t00，have been discovering its connective virtues.Physicists are using it;college students are using it;everybody is using it;and as a sign that it has come of age，the New Yorker has celebrated its liberating presence with a cartoon—an appreciative dog seated at a keyboard，saying happily，“on the Internet，nobody knows you’re a dog.”

根据下面内容，回答题：

Working an eight-hour day is a luxury for most professional people. Nowadays， the only way to guarantee an eight-hour working day is to have the kind of job where you clock on and off. Those professionals who have managed to limit their hours to what was， ~0 years ago， the average do not wish to identify themselves. "I can quite easily achieve my work within a normal day， but I don"t like to draw attention to it，" says one sales manager."People looked at me when I leave at 5 o"clock. Now， I put paperwork in my bag. People assume I"m doing extra hours at home. "

But more typical is Mark， who works as an account manager. He says， "My contract says I work from 9 until 5 with extra hours as necessary. It sounds as if the extra hours are exceptional. In fact， my job would be enough not only for me， but also for someone else part- time. The idea of an eight-hour day makes me laugh!" He says he has thought about going freelance but realizes that this doesn"t guarantee better working hours.

Professors Cary Cooper， occupational psycholo- gist at the University of Manchester， is the author of the annual Quality of Working Life survey. The most recent survey found that 77% of managers in Britain work more than their contracted hours， and that this is having a damaging effect on their health， relationships and productivity. Professor Cooper is critical of the long-hours culture. He says that while bosses believe long hours lead to greater efficiency， there is no evidence to support this. "In fact， the evidence shows that long hours make you ill. "

There am， he says， steps that can be taken. One is to accept that the in-tray will never be empty."There are always things to do. You just have to make the rule that on certain days you go home early. " Prioritising work and doing essential tasks first helps， he says. He also thinks it"s time to criticize bad employers and unreasonable terms of employment. " By all means， show commitment where necessary but when expectations are too high， people have to begin saying openly that they have a life outside of work. "

Personal development coach Mo Shapiro agrees that communication is important. Staff need to talk to managers about the working practices within a company. Both parties should feel that the expectations are realistic and allow them to have responsibilities and interests outside work. She recongnises， however， that in many organizations the response might well be， "If you want more interests outside work， then find another job. "

She believes that senior staff have a duty to set an example. "I recently worked for a finn of solicitors where the partners started at 7:30 a. m. What kind of message is that to send to the staff？" She believes there is no shame in working sensible hours in fact quite the reserve."Some people might be in at 7. 30 am but will be doing very little. You can work really hard from9 to 5 and achieve the same. If you find it difficult to achieve an eight-hour day， there is， as a last resort， the old trick of leaving your jacket on your chair and your computers switched on， even after you have left the building. "

What does the writer say in the first paragraph about people who work an eight-hour day？ 查看材料

A.They are reluctant to admit to this.

B.They are disliked by their colleagues.

C.They are limited to certain professions.

D.They often catch up on work in the evenings.
