课时提升作业二十九选修6Unit 4Global warming(限时35分钟)Ⅰ. 阅读理解AThe researchers’ findings will hardly come as a surprise to those who study air pollution. Previous research has shown that outdoor air pollution causes more than 3 million deaths annually and suggested that the figure could double by 2050.Another study suggested that air pollution causes 1. 6million premature(早产儿)deaths annually in China alone.Policy makers across the globe have responded to airpollution with a number of new regulations, many ofwhich focus on limiting pollution from coal. China stopped approval of new coal mines for three years at the end of 2015 and has issued strict requirements along the lines of those in the U. S. for new coal-fired power plants. Cities in China have also developed warning systems to get cars off the streets and limit industrial pollution during periods of intense smog. But even these policies may still be met by increases in mortality (死亡率)as aging populations are increasingly suffering fromthe problems associated with pollution.“China might move in the right direction in terms of air pollution, but it’s going to have to continue revising policies just like the U. S. and Euro pe, ” said Dan Greenbaum, president of Health Effects Institute, which supported the research.And, while premature deaths due to pollution in the U. S. and Europe have declined in recent decades, cities in the West have still taken steps to reduce pollution. Air pollution kills more than 200, 000 in Europe and nearly 80, 000 in the U. S. each year, according to the research. The benefits of addressing air pollution extend beyond the people who experience the health effects of poor air directly.“One of the unique things about air pollution is that you can’t run, you can’t hide from it, ” said study researcher Michael Brauer, a professor at the University of British Columbia, in a video accompanying the presentation. “But we know that if you improve air quality, everybody benefits from it. ”【文章大意】本文是一篇新闻报道。

细节理解题。
根据第三段可知, 中国还得持续调整相关政策。
故D项符合题意。
3. What can be inferred about the U. S. and Europe from the last but one paragraph?A. They have settled their environmental problems.B. They have cut their premature deaths to the lowest.C. Measures are still being taken to deal with pollution.D. Population killed by air pollution have increased.【解析】选C。
推理判断题。
根据倒数第二段内容可知, 虽然在美国和欧洲污染所致的早产儿死亡率在不断地下降, 但是西方的很多城市还会采取措施来减少污染, 因为采取措施治理空气污染所带来的好处也会有益于那些因空气质量差而健康遭受直接影响的之外的人们。
故C项符合题意。
B(2017·濮阳模拟)Royale is surrounded by deep blue waters of Lake Superior, the largest freshwater lake on Earth. The only way to get there is by boat or sea plane. The National Park Service operates shuttle boats that take visitors to Isle Royale. The boats leave from two Michigan ports. A boat trip to Isle Royale takes three to five hours. Waters are often extremely rough.Modern copper mining began in the late 1800s, resulting in large areas of the island being burned. This led to settlement development. Soon, Isle Royale became popular for summer homes. It became a national park on April 3, 1940. In 1980, officials named it an International Biosphere Reserve(生物圈保护区)because of its unique ecosystem.Isle Royale offers hiking, camping, boating, and even scuba diving. The National Park Service protects 11 sunken(沉没的)boats for divers to explore. They are reminders of Lake Superior’s commercial shipping history. The sunken wooden ship called The America is one of the most popular dive sites. The America carried passengers, mail, and supplies to many towns along the shores of Lake Superior. It first launched in 1898, and was used until 1928, when it was damaged. It sank to the bottom of the lake soon after.Visitors to Isle Royale share the trails with a well-studied populationof wolves. Scientists believe wolves walked there during a freeze of the lake sometime in the 1940s. Researchers closely record their population numbers. Much of the research takes place during the winter, when the trees are bare. The researchers fly over the island to observe the animals from above.Animal research is the only winter activity going on at Isle Royale. The national park is closed each year in late October because of the terrible weather conditions and reopens in spring time the next year.But for the other months of the year, Isle Royale offers green forests, and clear blue waters. Its excellent scenery and unusual location keep visitors returning year after year.【文章大意】本文属于说明文阅读, 作者通过这篇文章主要描述了苏必利尔湖的皇家岛屿的发展史和它的地理位置和地方特色。
