Passage OneQuestions 1 to 5 are based on the following passage.In late April, 33-year-old Li Yang climbed into her new car, Suzuki Alto and headed west. She “just kept going to see how far I could get.” Six days and 1,600 miles later, she arrived in Lhasa, the Tibetan capital. Exhausted and excited, she wrote an article and put it on the Internet, documenting her adventure with digital photos.For centuries such freedom of movement has been unimaginable in China. In feudal times, poverty, bad roads, and imperial edict confined people to the villages where they were born. Now all that is changing. With China’s economic development for decades, car ownership is suddenly within reach of millions of ordinary Chinese. As incomes rise, new car prices fall down quickly, and the government adds new roadways, many Chinese people think that it is enjoyable to have their own cars instead of bicycles. The increasing number of cars has launched a new cultural revolution, transforming Chinese life and society in many ways, just like what happened in America 50 years ago. The most obvious change is the traffic. Beijing’s broad streets are now filled with cars at rush hour. In Shanghai the bridges and tunnels crossing the Huangpu River witness so many cars that a cab ride from one side to the other can take more than an hour. To prevent traffic jams, the Shanghai city government auctions a limited number of new car license plates each month. Even with these restrictions, the number of cars on Chinese roads is increasing so fast it poses a grave threat to the environment and could reshape the global economics of oil.Private cars have brought about a new class of commuters, who drive to downtown office towers from spacious, modern homes in the suburbs. “I enjoy the drive,” says the manager of a Dutch food company, who takes the 30-minute-trip to his office in the center of Shanghai. He lives with his wife and infant son in a gated community with a familiar name: Long Island. “It would be probably cheaper to take a taxi every day,” he said. “But this way, I feel more comfortable and have more freedom.”4. What did the Shanghai government do to prevent traffic jams?
