【题目】B
When Beijing is hit by smog, residents often joke that the Chinese capital needs to build giant fans to clear out the polluted air. Mountains to the north and west help trap smog in the city, and a strong wind from Mongolia is the surest way to ensure cleaner air.
Beijing officials are now considering ways to help that process. Though giant fans are not on the menu, at least not yet, city planners are looking at ways to create corridors (走廊)that encourage wind flow through the capital. The plan is inspired by research on urban heat islands, which shows that large buildings that block the wind are one of the causes of higher average temperatures in cities as opposed to those in the countryside.
“This isn’t controlling pollution. It’s shifting the problem.” Wang Bing, a Beijing-based author, wrote on Sina Weibo. But the plan has received some interest from residents who have grown tired of repeated periods of heavy pollution.
Peng Yingdeng, an air pollution expert at the Beijing Municipal Research Institute of Environmental Protection, told the newspaper that the plan was more likely to require an adjustment of related laws to limit building heights and numbers in some areas. Similar proposals are under consideration in other major Chinese cities including Hangzhou, Nanjing, Shenyang and Wuhan.
“This kind of work to search for ways to reduce pollution is really worth applauding,” the state-run news agency Xinhua said in a commentary. “If scientists confirm it is effective, then we should promote it on a much larger scale.”
Some experts have expressed doubts whether the plan would make a significant difference. Serious pollution is usually associated with periods of little or no wind, and air corridors do little good if the wind isn’t blowing, Song Guojun, an environmental science professor told The Beijing News. Solving the air pollution problem mainly requires controlling pollution sources.
【1】Why do people say “the Chinese capital needs to build giant fans”?
A. Because the weather in Beijing is very hot.
B. Because they think air corridors are a good idea.
C. Because Beijing is surrounded by mountains.
D. Because the pollution is too serious.
【2】What is Wang Bing’ s attitude towards the construction of air corridors?
A. Disapproval. B. Supportive.
C. Cautious. D. Optimistic.
【3】Using air corridors to solve pollution problem largely depends on ______.
A. electricity B. wind
C. technology D. laws
【4】What is the solution to pollution problem according to Song Guojun?
A. To build giants fans.
B. To construct air corridors.
C. To control pollution sources.
D. To take the cars off the road.
【答案】
【1】D
【2】A
【3】B
【4】C
【解析】
【文章大意】在北京经历严重的雾霾天气时，居民们经常开玩笑说：北京需要竖立一些巨型风扇来把这种有毒的空气吹走。而目前相关部门正在考虑开辟一些能让风吹过北京的廊道来推动这一过程，但是对此也有人持质疑态度。
【1】D推理判断题。根据文章首段中的“When Beijing is hit by smog, residents often joke that the Chinese capital needs to build giant fans to clear out the polluted air.”可知人们这样说是因为北京的空气污染太严重了，选D。
【2】A态度观点题。由文章第三段中的“This isn’t controlling pollution. It’s shifting the problem.”可知Wang Bing不赞同这种措施，选A。
【3】B推理判断题。在第一段提出人们希望能用巨型风扇把有毒的空气吹走，然后在第二段介绍城市规划部门正在考虑开辟风道来应对污染问题，而文章末段又提出如果没有风刮过，那么风道对解决空气污染几乎起不到什么作用，选B。
【4】C细节理解题。从文章末段中的 “…solving the air pollution problem mainly requires controlling pollution sources. ”可知Song Guojun认为治理环境污染主要靠控制污染源，选C。
