Traffic Jams一No End in Sight
1 Traffic congestion（拥堵）affects people throughout the world. Traffic jams cause smog in dozens of
cities across both the developed and developing world. In the U. S.,commuters（通勤人员）spend an
average of a full working week each year sitting in traffic jams,according to the Texas Transportation Institu-
te.While alternative ways of getting around are available,most people still choose their cars because they are
looking for convenience,comfort and privacy.
2 The most promising technique for reducing city traffic is called congestion pricing,whereby cities
charge a toll to enter certain parts of town at certain times of day.In theory,if the toll is high enough,some
drivers will cancel their trips or go by bus or train.And in practice it seems to work:Singapore,London and
Stockholm have reduced traffic and pollution in city centres thanks to congestion pricing.
3 Another way to reduce rush-hour traffic is for employers to implement flexitime,which lets employees
travel to and from work at off-peak traffic times to avoid the rush hour. Those who have to travel during busy
times can do their part by sharing cars.Employers can also allow more staff to telecommute(work from
home)so as to keep more cars off the road altogether.
4 Some urban planners still believe that the best way to ease traffic congestion is to build more roads,
especially roads that can take drivers around or over crowded city streets.But such techniques do not really
keep cars off the road;they only accommodate more of them.
5 Other,more forward-thinking,planners know that more and more drivers and cars are taking to the
roads every day,and they are unwilling to encourage more private automobiles when public transport is so
much better both for people and the environment.For this reason,the American government has decided to
spend some$7 billion on helping to increase capacity on public-transport systems and upgrade them with
more efficient technologies.But environmentalists complain that such funding is tiny compared with the$50
billion being spent on roads and bridges.

问答题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. They say that cities will become more and more crowded and many other problems will be caused by this 1 Due to the hard life, people do not want to live in 2 These urban problems such as overcrowding, crime and traffic have been getting worse, so many people 3 for the future of the city. However, these disadvantages of any modern city are not unique to that city. All the cities all over the world must solve the problems and fortunately, many of them have found answers to one or more of these difficulties. For example, 4 or London has planned communities providing people with apartments, jobs and so on. Besides, many U. S. cities 5 In a word, solutions that have been successful in a place should be adopted and tried in another place.
