Most companies expect IT (Information Technology) managers to head an IT staff of computer technicians. But IT managers can also specialize in other areas. Some managers may also be responsible for keeping their company’s Internet safety. They protect both their company and their online customers from thieves.Other managers focus more on the business rather than the technical part of computing. They become project managers, helping companies reach as many online customers as possible.Some companies also look for IT managers who can act as trainers. These trainers help a company’s computer technicians keep up-to-date on computer skills.Most companies require their IT managers to have both a bachelor’s degree and some experience in the computer field. Often, companies hire IT managers out of their existing staff of computer technicians.Since IT managers are extremely important to companies’ success, it’s no surprise that they receive such high salaries – around US $56,000 a year to start with. And, in such a fast-changing field,managers’ salaries usually increase after only a couple of years.The world will be watching to see just how quickly e-commerce replaces the old ways of doing business. And as computers change the way the world does business, IT managers will be in the middle of it all. Few companies can survive without them.Besides being the leader of computer technicians, IT managers are also expected to be ________.(A) experienced product designers(B) skilled online technicians(C) doctorate holders(D) online safety specialists
According to the passage, companies often look for IT managers from ________.(A) non-computer technicians(B) their own professionals(C) other companies(D) another country

Passage ThreeThe whole industrial process which makes many of the goods and machines we needand use in our daily lives, is bound to create a number of waste products whichupset the environmental balance or the ecological(生态的)balance as it is known. Many of these waste products can be prevented or disposed(处理) of sensibly, but clearly while more and more new goods are produced and made complex, there willbe new, dangerous wastes to be disposed of, for example, the waste products from nuclear powerstations. Many people therefore see pollution as only part of a larger and more complex problem, that is,the whole process of industrial production and consumption of goods. Others see the problem mainly inconnection with agriculture, where new methods are helping farmers grow more and more on theirland to feed our everincreasing population. However, the land itself is graduallybecoming worn out as it is being used, in some cases, too heavily, and artificialfertilizers(人造肥料) cannot bring back the balance.Whatever is underlying(潜在的)reasons, there is no doubt that much of the pollution caused could be controlled if only companies,individuals and governments would make more efforts. In the home there is an obvious need to control litter(杂乱的废物)and waste. Food is wrapped up three or four times in packages that all have to be disposed of; drinks areincreasingly sold in bottles or tins which cannot be reused. This not only causes a litter problem, but also isa great waste of resources, in terms of glass, metals and paper. Advertising has helped this process bypersuading many of us to buy things we don't want to buy. Pollution and waste continue to be a problemeveryone can help to solve by cutting out unnecessary buying, excess consumption and careless disposal ofthe products we use in our daily lives.44. The main cause of pollution is______.A. the production of new industrial goodsB. increased amounts of unnatural substanceC. our ever-increasing populationD. the release of artificial substances into the environment
BFor several years，Americans have enjoyed teleshopping-watching TV and buying things by phone． Now，teleshopping is starting in Europe．ln a number of European countries，people can turn on their TVs and shop for clothes，jewelry，food，toys and many others things．Teleshopping is becoming popular in Sweden． For example，the biggest Swedish company sells different kinds of things on TV in 15 European countries，and in one year it made $ 100 million．In France，there are two teleshopping channels，and the French spend $ 20 million a year to buy things through those channels．In Germany，until last year teleshopping was only possible on one channel for one hour ev-ery day． Then the government allowed more teleshopping． Other channels can open for telebusi-ness，including teleshopping companies． German businesses are hoping this new teleshopping will help them sell more things．Some people like teleshopping because it allows them to do their shopping without leaving their homes． With all the problems of traffic in the cities，this is an important reason．But at the same time，other Europeans do not like this new way of shopping． They call teleshopping "just on the air． "Many Europeans usually worry about the quality of the things for sale on TV． Good quality is important to them，and they believe they can't be sure about the quality of the things on TV．The need for high quality means that European teleshopping companies will be different from the American companies． They will have to be more careful about the quality of the things they sell． They will also have to work harder to sell things that the buyers can-t touch or see in person．( )26．In which country people can go teleshopping?A． America and all the European countries．B． Australia and some European countries．C． The USA and many European countries．D． America and many developed countries．

Five years ago, David Smith wore an expensive suit to work every day． "I was a clothes addict," he jokes． "I used to carry a fresh suit to work with me so I could change if my clothes got wrinkled．" Today David wears casual clothes--khaki pants and a sports shirt to the office． He hardly ever wears a necktie． "I'm working harder than ever," David says, "and I need to feel comfortable．" More and more companies are allowing their office workers to wear casual clothes to work． In the United States, the changes from formal to casual office wear have been slow． In the early 1990s, many companies allowed their workers to wear casual clothes on Friday (but only on Friday)． This became known as "dress-down Friday" or "casual Friday"． "What started out as an extra one-day-a-week benefit for workers has really become an everyday thing．" said business adviser Maisly Jones． Why have so many companies started allowing their workers to wear casual clothes' One reason is that it's easier for a company to attract new workers if it has a casual dress code． "A lot of young people don't want to dress up for work," says the owner of a software company, "so it's hard to hire people if you have a conservative dress code．" Another reason is that people seem happier and more productive when they are wearing comfortable clothes． In a study made by Levi Strauss and Company, 85 percent of employers said that casual dress has a side effect on work． Supporters of casual office wear also say that a casual dress code helps them save money． "Suits are expensive, if you have to wear one every day," one person said． "For the same amount of money, you can buy a lot more casual clothes．" According to this passage, which of the following is FALSE? ( )A. Many workers don't like a conservative dress code．B. Comfortable clothes make workers more productive．C. A casual clothes code is welcomed by young workers．D. All the employers in the U．S． are for casual office wear．
Text 4 Alphabet Inc.'s most successful product-the Google search engine-may now be its most problematic.On Tuesday,the European Commission's top antitrust regulator levied a$2.7-billion fine against Alphabet and Google for the way the search engine handles requests for information about products.Specifically,Commissioner Margrethe Vestager said that Google twisted its results to bury links to rival companies'comparison shopping sites while prominently featuring its own service,Google Shopping.Google responded that it's simply trying to give users what they want and denied"favoring ourselves,or any particular site or seller."It has a lot at stake:Google has integrated many different offerings into its search engine,including its mapping and travel services.The principle advanced by Vestager,however,is a good one:Giant online companies shoulcl not be able to take advantage of their dominance in one field to hurt competitors in another.Google's argument is:It integrated Google Shopping,which offers links to products at sites that advertise on Google.into its search engine because that gave users quicker access to the information they were seeking.And in the United States,the key question in antitrust!aw is whether a company's behavior hurts users,not whether it hurts the company's competitors.European regulators focus more on competitors,but they really are two sides of the same coin.If competitors are unfairly closed out,the public can miss out on the very real benefits that vigorous competition provides.At the same time,it's undeniable that the public has welcomed virtual monopolies in search,social media and other services in the Internet era.A large part of the appeal of sites like Facebook and Twitter is that so many people use them.There's a network effect for social media apps in particular-the more people who use the service,the more valuable it becomes to them.Meanwhile,start-ups come out of nowhere to create whole new categories of must-have apps and proclucts online.That means dominant companies have to innovate too,or else they can easily change from today's thing to yesterday's.And often,that innovation involves finding a better way to do something that a competitor is doing.The challenge for regulators is to provide the big companies space to try new things without grossly disrupting the market,closing out other companies and reducing consumer choice,which will ultimately lead to less innovation.A good place to start is by focusing on cases where there is evidence of intentional undermining of competitors-where a dominant company alters the platform it provides not just to feature its own services,but to make it harder to find or use its rivals'.The author argues that regulators should_____A.leave room for dominant companies to innovateB.help small companies enhance competitivenessC.encourage companies to increase product varietyD.prohibit featuring services on company platforms
Text 3 Employees are often said to be a company's biggest resource.It is equally true that they are its biggest liability.Scarcely a week goes by without a company falling victim to employees-turned-cnemies-or-embarrassments.The most familiar type of enemy within is the fraudster.The Economist Intelligence Unit conducts a regular poll of senior executives on the subject of fraud committed by insiders.Two year ago the poll discovered that about 70%of companies had suffered from at least one instance of fraud,up from 61%in the previous survey.Fraud is often petty.But fraud can also be more harmful:think of former employees setting up rivals using stolen technology and purloined client lists.Even more dangerous is the vandal.Thieves at least have a rational motive.Vandals are driven by a desire for revenge that can know no limit.A company that specialises in corporate investigation gives a detailed account of the story of a British manufacturing company that was under restructuring.A member of the infonnation technology department discovered that his name was on the list of people whose services would no longer be required.He built a"backdoor"into the company's IT system from his home computer and set about causing damage.What can companies do to reduce the threat from these wolves in sheep's clothing?A lot depends on which particular sorts ofwolves you are dealing with.Yet three principles are always worth bearing in mind.The first is that firms need to focus on the people who have the greatest capacity to do harm-those who control the money and information.The more complicated companies become,the harder it is to identify where power really lies.But one thing is clear.The more dependent on information firms get,the more IT specialists can compromise the whole business.The least companies can do is to keep a careful watch on the IT department.The second is that the human touch is still invaluable.Companies can certainly strengthen their hand by installing software that can identify unusual behaviour or monitor e-mail,or by employing professionals to double-check the accounts.The best way to avoid these problems is to treat our employees with respect.The biggest problem with trying to do more with less is that you can end up tuming your biggest resources into your biggest liabilities.The study conducted by the Economist Intelligence Unit informs us that_____A.many companies are stolen by thievesB.a large number of companies suffer from liarsC.senior executives are more likely to commit fraudD.rivals will steal technology and client lists

问答题Practice 4 In the first year or so of Web business, most of the action has revolved around efforts to tap the consumer market. More recently, as the Web proved to be more than a fashion, companies have started to buy and sell products and services with one another. Such business-to-business sales make sense because businesspeople typically know what product they’re looking for. Nonetheless, many companies still hesitate to use the Web because of doubts about its reliability. “Businesses need to feel they can trust the pathway between them and the supplier,” says senior analyst Blane Erwin of Forrester Research.
