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.

Remember to write the answers on the Answer Sheet.　　As a result of all these factors, when the recession eases and people find more confidence, there will be an explosion of employees seeking new opportunities to escape their current jobs. This will be led by younger, less-experienced employees and the hard - headed young graduates. ‘Headhunters’ confirm that older staff are still cautious, having seen so many good companies ‘go to the wall’, and are reluctant to jeopardize their redundancy entitlements. Past experience, however, suggests that, once triggered, the expansion in recruitment will be very rapid.　　The problem which faces many organizations is one of strategic planning; of not knowing who will leave and who will stay. Often it is the best personnel who move on whilst the worst cling to the little security they have. This is clearly a problem for companies, who need a stable core on which to build strategies for future growth.　　Whilst this expansion in the recruitment market is likely to happen soon in Britain, most employers are simply not prepared. With the loss of middle management, in a static marketplace, personnel management and recruitment are often conducted by junior personnel. They have only known recession and lack the experience to plan ahead and to implement strategies for growth. This is true of many other functions, leaving companies without the skills, ability or vision to structure themselves for long-term growth. Without this ability to recruit competitively for strategic planning, and given the speed at which these changes are likely to occur, a real crisis seems imminent.　　SUMMARY:　　Taking all of these various factors into consideration, when the economy picks up and people 　1　there will be a very rapid expansion in recruitment.

Directions:In this section, there is one passage followed by a summary. Read the passage carefully and complete the summary below by choosing no more than three words from the passage. Remember to write the answers on the Answer Sheet.　　Questions 1-5 are based on the following passage.The City of the Future　　What will city life be like in the future? Some people think that life in the cities is going to be horrible. They predict that cities will become more and more crowded. As the number of people increases, there will be less space for each person. This overcrowding will cause other problems—more crime, dirtier streets, and worse problems with traffic than we have now. How will people find enough drinking water, energy (such as gas and electricity), and housing? Because life will be hard, people who live in cities will worry more, and they may become sick. For these reasons, some say that nobody will want to live in urban areas.　　How can we solve such problems as overcrowding, crime, and traffic? In some cities, thousands of people are already sleeping in the streets because there is so little suitable housing—and because rents are so high. The crime rate isn’t going down. Instead, it is increasing so fast that many people are afraid to go out at night. Traffic is also getting worse. More and more often, traffic jams are so bad that cars don’t move at all for several blocks. These urban problems have been getting worse, not better, so many people see no hope for the future of the city.　　Los Angeles, California, for instance, has no subway system and the buses are slow. Instead, most commuters drive many miles from their homes to work. Many of these drivers spend several hours each day on busy freeways. New York, by contrast, has a mass transit system—buses, commuter trains, and subways. Because the public transportation is crowded and dirty, however, many people drive private cars, and the traffic jams are worse than in Los Angeles.　　On the other hand, some cities have clean, fast, and pleasant public transportation systems. In Paris, France, and Toronto, Canada, for example, anyone can use mass transit to move quickly from one part of the city to another.　　The disadvantages of any modern city are not unique to that city—that is, cities all over the world have to solve the problems of traffic jams, crime, housing, energy, drinking water, and overcrowding. Yet many cities have found answers to one or more of these difficulties. Some European cities, such as Stockholm, Sweden, or London, England, have planned communities that provide people with apartments, jobs, shopping centers, green space, entertainment, and transportation. Many U.S. cities are rebuilding their downtown areas. Urban planners can learn from one another. They can try solutions that have been successful in other parts of the world.　　Summary:　　Some people think that life in the cities is going to be horrible.
