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.

Which of the following questions is answered according to the passage?

Smoking bans in public places are becoming more and more common in China. Whether the right of the non-smoker to breathe in fresh air outweighs that of the smoker to smoke freely is a matter of opinion, manifesting itself in a heated smoking ban debate. The following are opinions from both sides on this issue. Read the excerpts carefully and write your response in about 300 words, in which you should:　　1. summarize briefly the opinions from both sides, and then　　2. give your comment.　　Marks will be awarded for content relevance, content sufficiency, organization and language quality.

There are many reasons why smoking bans originated, but most of these have medical origins. Research has shown secondhand smoke is almost as harmful as smoking in and of itself. The effects of secondhand smoke are relatively the same as smoking. Lung disease, heart disease, bronchitis and asthma are common. Those who live in homes with smokers have a 20-30 percent higher risk of developing lung cancer than those who do not live with a smoker.　　Smoking bans are also imposed because they improve air quality in restaurants and other establishments. In Beijing, it is now illegal to smoke in all hospitality venues. Studies have also shown employees are exposed to far fewer toxins in areas where smoking is banned in the workplace.　　Despite the positive effects on health and air quality, many people are still opposed to smoking bans in China. Critics oppose smoking bans and see these laws as an example of the government interfering in people’s lives. They look at the effects on smokers, not those on non-smokers who are subjected to second-hand smoke. Other critics emphasize the rights of the property owner and draw distinctions between public places, such as government building and privately owned businesses, such as stores and restaurants.　　Some critics of smoking bans believe that outlawing smoking in the workplace may cause smokers to simply move their smoking elsewhere. Instead of smoking indoors, workers may begin smoking in public parks and exposing a new set of people to their secondhand smoke.
