33、PART READING COMPR(总题数：0，分数：0.00)九、TEXT A(总题数：1，分数：5.00)A simple piece of rope hangs between some environmentally friendly Americans and their neighbors. On one side stand those who have begun to see clothes dryers as wasteful consumers of energy (up to 6% of total electricity) and powerful emitters
34、 of carbon dioxide (up to a ton of CO2 per household every year). As an alternative, they are turning to clotheslines as part of what Alexander Lee, an environmentalist, calls what-I-can- do environmentalism.But on the other side are people who oppose air-drying laundry outside on aesthetic grounds.
35、 Increasingly, they have persuaded community and homeowners associations (HOAs) across the U.S. to ban outdoor clotheslines, which they say not only look unsightly but also lower surrounding property values. Those actions, in turn, have sparked a right-to-dry movement that is pressing for legislatio
36、n to protect the choice to use clotheslines. Only three statesFlorida, Hawaii and Utahhave laws written broadly enough to protect clotheslines. Right-to-dry advocates argue that there should be more.Matt Reck is the kind of eco-conscious guy who feeds his trees with bathwater and recycles condensati
37、on drops from his air conditioners to water plants. His family also uses a clothesline. But Otto Hagen, president of Recks HOA in Wake Forest, N.C., notified him that a neighbor had complained about his line. The Recks ignored the warning and still dry their clothes on a rope in the yard. Many peopl
38、e claim to be environmentally friendly but dont take matters into their own hands, says Reck. HOAs Hagen has decided to hold off taking action. Im not going to go crazy, he says. But if Matt keeps his line and more neighbors complain, Ill have to address it again.North Carolina lawmakers tried and f
39、ailed earlier this year to insert language into an energy bill that would expressly prevent HOAs from regulating clotheslines. But the issue remains a touchy one with HOAs and real estate agents. Most aesthetic restrictions are rooted, to a degree, in the belief that homogenous (统一协调的) exteriors are
40、 supportive of property value, says Sara Stubbins, executive director of the Community Association Institutes North Carolina chapter. In other words, associations worry that housing prices will fail if prospective buyers think their would-be neighbors are too poor to afford dryers.Alexander Lee dism
41、isses the notion that clotheslines devalue property assets, advocating that the idea needs to change in light of global warming. We all have to do at least something to decrease our carbon footprint, Alexander Lee says.（分数：5.00）(1).What is NOT mentioned as a disadvantage of using clothes dryers?A. E
