This is not the world we know. This world is controlled by computers. Men and women canbe 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 dont 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 dont know anything about computersB：they havent 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 peoples needs in various situations(5)、The authors attitude towards widely used computers is __.A：positiveB：anxiousC：worriedD：serious查看答案请关注【快跑搜题】微信公众号，发送题目即可获取第7题
Digital NativesDavid is not very comfortable with new technology and he does not have maDigital NativesDavid is not very comfortable with new technology and he does not have many gadgets. Lucy loves new technology. She owns a games console, an MP3 player, and a mobile phone with a built-in digital camera. David is a teacher. Lucy is his student.Like Lucy, many children grow up using computers almost every day and often know more about technology than adults. Educator Marc Prensky calls children like Lucy “digital natives”. Digital natives can quickly learn how to use new gadgets and new software, while non-digital natives spend a lot of time reading manuals and worrying about computer viruses. In fact, many parents try to save time by asking their children to teach them how to use new technology!The divide between digital natives and non-digital natives can cause problems at school because students and teachers grow up with very different ideas about technology. Many teachers think that playing computer games is a waste of time and that technology has made children unable to concentrate. However, many students think their classes are slow and boring, and want to use computers to study.Prensky believes that digital natives have learned a lot from technology, but that they learn things in a different way. For example, reading a website is different from reading a book, so digital natives are good at finding the information they need and choosing what they want to read. So perhaps teachers need to change the way they teach and use more technology in class – because the number of digital natives will keep increasing!1.David is a digital native.()2.Marc Prensky is interested in teaching with technology.()3.Digital natives are comfortable using laptops and flash drives.()4.Many teachers think computer games are only for having fun or killing time.()5.People read books and websites in the same way.()查看答案请关注【快跑搜题】微信公众号，发送题目即可获取第8题
More and more, the operations of our businesses, governments, and financial institutions are controlled by information that exists only inside computer memories. Anyone clever enough to modify this information for his own purposes can reap substantial rewards. Even worse, a number of people who have done this and been caught at it have managed to get away without punishment.It’s easy for computer crimes to go undetected if no one checks up on what the computer is doing. But even if the crime is detected, the criminal may walk away not only unpunished but with a glowing recommendation from his former employers.Of course, we have no statistics on crimes that go undetected. But it’s disturbing to note how many of the crimes we do know about were detected by accident, not by systematic inspections or other security procedures. The computer criminals who have been caught may been the victims of uncommonly bad luck.For example, a certain keypunch operator complained of having to stay overtime to punch extra cards. Investigation revealed that the extra cards she was being asked to punch were for dishonest transactions. In another case, dissatisfied employees of the thief tipped off the company that was being robbed.Unlike other lawbreakers, who must leave the country, commit suicide, or go to jail, computer criminals sometimes escape punishment, demanding not only that they not be charged but that they be given good recommendations and perhaps other benefits. All too often, their demands have been met.Why? Because company executives are afraid of the bad publicity that would result if the public found out that their computer had been misused. They hesitate at the thought of a criminal boasting in open court of how he juggled the most confidential records right under the noses of the company’s executives, a accountant,and security staff. And so another computer criminal departs with just the recommendations he needs to continue his crimes elsewhere.1. It can be concluded from the passage that ().A. it is still impossible to detect computer crimes todayB. computer crimes are the most serious problem in the operation of financial institutionsC. computer criminals can escape punishment because they can’t be detectedD. people commit computer crimes at the request their company2.It is implied in the third paragraph that ().A. many more computer crimes go undetected than are discoveredB. the rapid increase of computer crimes is a troublesome problemC. most computer criminals are smart enough to cover up their crimesD. most computer criminals are smart enough to cover up their bad luck3. Which of the following is mentioned in the passage?()A. A strict law against computer crimes must be enforced.B. Companies need to impose restrictions on confidential information.C. Companies will guard against computer crimes to protect their reputation.D. Companies usually hesitate to uncover computer crimes.4.What may happen to computer criminals once they are caught?()A. With a bad reputation they can hardly find another job.B. They will be denied access to confidential records.C. They may walk away and easily find another job.D. They must leave the country or go to jail.5.The passage is mainly about ().A. why computer crimes are difficult to detect by systematic inspectionsB. why computer criminals are often able to escape punishmentC. how computer criminals manage to get good recommendation from their former employersD. why computer crimes can’t be eliminated
