Although the idea of “zero emission, and sustainable(可持续的) development” was promoted worldwide, most cities are at a loss what to do or even some have objected to it. But in Liuzhou, a city in southern China, attitudes could not be more different.
The Liuzhou Municipality Urban Planning Bureau has signed up Italian architect Stefano Boeri, the father of the forest city movement, to build a self­contained community for up to 30，000 people. He is the go­to man for such projects thanks to the success of his “vertical forests”， two residential(住宅的) towers. Completed in 2014, they remove up to 17.5 tons of soot(煤烟) from the air each year,  and a year later one of them was named Best Tall Building Worldwide.
The Liuzhou project is a much more ambitious undertaking, however. Its homes, hospitals, hotels, schools and offices will be built on a 340­acre site in what Boeri calls the first attempt to create an “urban environment that is really trying to find a balance with nature”. Its 100 species of plant life are expected to absorb almost 10,000 tons of carbon dioxide and 57 tons of pollutants per year, while at the same time producing 900 tons of life­giving oxygen.
Although the architects haven’t published the cost of the forest city, the Milan towers cost only five percent more than traditional skyscrapers.
The construction of his forest city at Liuzhou is set to begin in 2020, and there is still a great deal of planning and research required before a projected completion date can be set. However, Boeri remains optimistic about the project and has confidence in the soundness of his vision：“I really think that bringing forests into the city is a way to deal with global warming.”

阅读理解B
【解题导语】　为了改善空气质量，中国委托米兰建筑师Stefano Boeri为柳州市建造一座可以容纳3万人的森林城市。
4．A　解析：观点态度题。根据第一段可知，多数城市对待可持续发展的观点都是茫然不知所措，甚至有些城市还持反对意见。然而柳州市对待可持续发展的态度完全不同。所以可以看出柳州市对待可持续发展的态度是“支持的”。A.赞成的，支持的；B.小心的，谨慎的；C.不利的，不赞成的；D.怀疑的。故A项符合题意。
5．D　解析：推理判断题。根据第二段中的“He is the go­to man for such projects thanks to the success of his ‘vertical forests’， two residential(住宅的) towers.”可知，他设计的“垂直森林”——两栋住宅建筑的成功使得他成为此类项目的不二人选。所以可以推断出柳州项目签约Stefano Boeri的原因是“他已经有类似工程的经验”，故选D。
6．B　解析：代词指代题。根据画线词所在的句子可知，完工于2014年，它们每年可以去除空气中17.5吨的煤烟。所以可以推断出此处的they指代的是前句中的“两栋住宅楼”。A.建筑师们；B.两栋住宅楼；C.城市里的森林；D.城市居民。故选B。
7．D　解析：推理判断题。根据最后一段最后一句可知，Boeri对这个项目充满信心，他认为把森林引入城市中是一种应对全球变暖的方法。所以可以推断出柳州工程的目的是“改善环境”，故选D。
