At his factory in lvera, he designed and produced the first Italian typewriter. Today the company’s head office is still in Ivrea, near Turin, but the company is much lareer than it was in those days and there are offices all around the world.By 1930 there was a staff of 700 and the company turned out 13,000 machines a year. Some went to customers in Italy, but Olivetti exported more typewriters to other countries.Camilllo’s son, Adriano, started working for the company in 1924 and later he became the boss. He introduecd a standard speed for the production line and he employed technology and desion specialists. The company developed new and better typewriters and the calculators（计算器）.In 1959 it prodyced the ELLA computer system. This was the first mainframe（主机）computer designed and brade in Italy.After Adriano died in 1960, the company had a period of financial problems. Other companies, especially the Janpanese, made faster progress in electronic technology than the Italian company.In 1978, Carlo de Benedetti became the new boss. Olivetti increased its marking and service networks and made agreements with other companies to design and produce more advanced office equipment. Soon it became one, of the world’s leading companies in informationg technology and communications. There are now five independent companies in the Olivetti group --- one for personal computers,one for other office equipment, one for systerms and servicse, and two for telecommunications.56.From the text we learn that__________.A.by 1930 Olivetti produced 13,000 typewriters a yearB. Olivetti earned more in the 1960s than in the 1950sC.some of Olivetti,s 700 staff regularly visited customers in ItalyD. Olivetti set up offices in other countries from the very beginning
What do we know about Olivetti ?A.It produced the best typewriter in the word.B.It designed the word’s first mainframe. computer.C.It exported more typewriter than other computer.D.It has five independent companies with its head office in lvrea.
AIn China，more and more middle school students are getting shorter sleeping time than be-fore． Most students sleep less than nine hours every night，because they have much homework to do. Some homework is given by their teachers，and some by their parents． Also，some students don't know how to save time .They are not careful enough while they do their homework，so it takes them a Iot of time． Some students spend too much time watching TV or playing computer games．They stay up very late． Some students have to get up early every morning on weekdays to get to school on time by bus or by bike．lt can be a long way from home to school．Schools and parents should cut down some of the homework so that our children can enjoy more than nine hours of sleep every night for their health． For children，we should make best use of our time． When we have enough time for sleeping，we will find it much better for both our study and health．( )21． What makes most students sleep less than nine hours every night?A． Watching TV．B． Playing computer games．C． Doing their homework．D． Doing housework．
This is not the world we know. This world is controlled by computers. Men and women can be seen, but they are following the orders given to them by machines. The machines were designed by mad scientists, but at some point even the mad scientists were taken over by their super-inventions.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. Somefactory 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 moreefficient 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.(1)、According to the passage, our present world is under the control of ______ .A：mad scientistsB：men and womenC：the unknown fearD：some super-inventions(2)、The reason why many people are afraid of computers is that ______ .A：they don't know anything about computersB：they haven't really understood computersC：there are so many computer gamesD：computers are often down(3)、The author mentions computer wizards in order to point out that ______ .A：computers can be controlled by manB：there should be more people devoted to computersC：only young people are interested in computersD：more time and energy is required to control computers(4)、This passage is probably written to suggest that ______ .A：some day computers can deal with all human problemsB：computers can be used in place of traveling to our jobsC：people should not fear computersD：computer technology will not meet people's needs in various situations(5)、The author's attitude towards widely used computers is __.A：positiveB：anxiousC：worriedD：serious

共用题干第二篇The next big breakthrough in artificial intelligence could come from giving machines not just more logical capacity,but emotional capacity as well.Feeling aren't usually associated with inanimate（无生命的）machines, but Posalind Picard, a professor of computer technology at MIT,believes emotion may be just the thing computes need to work effectively.Computers need artificial emotion both to understand their human users better and to achieve self-analysis and self-improvement,says Picard."If we want computers to be genuinely intelligent,to adapt to us,and to interact naturally with us,then they will need the ability to recognize and express emotions,to have emotions,and to have what has come to be called emotional intelligence,"Picard says.One way that emotions can help computers,she suggests,is by helping keep them from crashing. Today's computers produce error messages,but they do not have a "gut feeling" of knowing when something is wrong or doesn't make sense.A healthy fear of death could motivate a computer to stop trouble as soon as it starts.On the other hand, self-preservation would need to be subordinate to service to humans.It was fear of its own death that promoted RAL,the fictional computer in the film 2002 :A Space Odyssey, to extermine（消灭）most of its human associates.Similarly,computers that could"read"their users would accumulate a store of highly personal information about us一not just what we said and did,but what we likely thought and felt."Emotion not only contribute to a richer quality of interaction,but they directly impact a person's ability to interact in an intelligent way,"Picard says."Emotional skills,especially the ability to recognize and express emotions,are essential for natural communication with humans." According to Picard,emotion intelligence is necessary to computers because_________.A:it can make computers analyze the information more efficientlyB:it can help to eliminate the computrs' innate problemsC:it can improve the mechanic capacity of computersD:it can make computers achieve a better understanding of human users

共用题干HackingPeople tend to think of computers as isolated machines,working away all by themselves.Some do-personal computer without an outside link, like someone's hideaway（隐蔽的）cabin in the woods.But just as most of homes are tied to a community by streets,bus routes and electric lines,computers that exchange intelligence are part of a community-local,national and even global network joined by telephone connections.The computer network is a creation of the electric age,but it is based on old-fashioned trust. It cannot work without trust. A rogue loose（为所欲为的无赖）in a computer system called hacker（黑客）is worse than a thief entering your house. He could go through anyone's electronic mail or add to,change,distort or delete anything in the information stored in the computer's memory .He could even take control of the entire system by placing his own instructions in the software that runs it.He could shut the computer down whenever he wished,and no one could stop him.Then he could program the computer to erase any sign of his ever having been there.Hacking,our electronic- age term for computer break-in,is more and more in the news-brainy kids vandalizing university records, even pranking（胡闹）about in supposedly safeguard-ed systems.To those who understand how computer networks are increasingly regulating life in the late 20th century,these are not laughing matters.A potential for disaster is building:A dissatis- fled former insurance-company employee wipes out information from payroll（工资表）files. A student sends out a“virus”,a secret and destructive command,over a national network .The vi-rus copies itself at lightning speed,jamming the entire network-thousands of academic,commer-cial and government computer systems.Such disastrous cases have already occurred.Now exists the possibility of terrorism by computer. Spoiling a system responsible for air-traffic control at a busy airport,or knocking out the telephones of a major city,is a relatively easy way to spread panic .Yet neither business nor government has done enough to toughen its defenses against at-tack .For one thing,such defenses are expensive;for another,they may interrupt communica- tion—the main reason for using computers in the first place. The writer mentions“a thief"” in the second paragraph______.A: to show that a hacker is more dangerous than a thiefB: to tell people that thieves like to steal computers nowadaysC: to demand that a protective computer system should be set up against thievesD: to demonstrate that hackers and thieves are the same people
