In 1994 there were nearly 20,000 wind turbines worldwide, most grouped in clusters called wind farms that collectively produced 3,000 megawatts of electricity. Most were in Denmark (which got 3 percent of its electricity from wind turbines) and California (where 17,000 machines produced 1 percent of the state’s electricity, enough to meet the residential needs of a city as large as San Francisco). In principle, all the power needs of the United States could be provided by exploiting the wind potential of just three states—North Dakota, South Dakota, and Texas.  Large wind farms can be built in six months to a year and then easily expanded as needed. With a moderate to fairly high net energy yield, these systems emit no heattrapping carbon dioxide or other air pollutants and need no water for cooling。 at least million die annually from pollution and poisoning。 manufacturing them produces little water pollution. The land under wind turbines can be used for grazing cattle and other purposes, and leasing land for wind turbines can provide extra ine for farmers and ranchers.  2. The word emit in the passage is closest in meaning to  ○Use  ○Require  ○Release  ○Destroy  Paragraph 3: Wind power has a significant cost advantage over nuclear power and has bee petitive with coalfired power plants in many places. With new technological advances and mass production, projected cost declines should make wind power one of the world’s cheapest ways to produce electricity. In the long run, electricity from large wind farms in remote areas might be used to make hydrogen gas from water during periods when there is less than peak demand for electricity. The hydrogen gas could then be fed into a storage system and used to generate electricity when additional or backup power is needed.  Paragraph 4: Wind power is most economical in areas with steady winds. In areas where the wind dies down, backup electricity from a utility pany or from an energy storage system bees necessary. Backup power could also be provided by linking wind farms with a solar cell, with conventional or pumpedstorage hydropower, or with efficient naturalgasburning turbines. Some drawbacks to wind farms include visual pollution and noise, although these can be overe by improving their design and locating them in isolated areas.  3. Based on the information in paragraph 3 and paragraph 4, what can be inferred about the states of North Dakota, South Dakota, and Texas mentioned at the end of paragraph 1?  ○They rely largely on coalfired power plants.  ○They contain remote areas where the winds rarely die down.  ○Over 1 percent of the electricity in these states is produced by wind farms.  ○Wind farms in these states are being expanded to meet the power needs of the United States.  4. According to paragraph 3, which of the following is true about periods when the demand for electricity is relatively low?  ○These periods are times when wind turbines are powered by hydrogen gas.  ○These periods provide the opportunity to produce and store energy for future use.  ○These periods create storage problems for all forms of power generation.  ○These periods occur as often as periods when the demand for electricity is high.  5. In paragraph 4, the author states that in areas where winds are not steady  ○Power does not reach all customers  ○Wind farms cannot be used  ○Solar power is more appropriate  ○B(yǎng)ackup systems are needed  6. According to paragraph 4, what can be inferred about the problems of visual pollution and noise associated with wind farms?  ○B(yǎng)oth problems affect the efficiency of wind farms.  ○Possible solutions are known for both problems.  ○Wind power creates more noise than visual pollution.  ○People are more concerned about visual pollution than noise.  Paragraph 5: Large wind farms might also interfere with the flight patterns of migratory birds in certain areas, and they have killed large birds of prey (especially hawks, falcons, and eagles) that prefer to hunt along the same ridge lines that are ideal for wind turbines. The killing of birds of prey by wind turbines has pitted environmentalists who champion wildlife protection against environmentalists who promote renewable wind energy. Researchers are evaluating how serious this problem is and hope to find ways to eliminate or sharply reduce this problem. Some analysts also contend that the number of birds killed by wind turbines is dwarfed by birds killed by other humanrelated sources and by the potential loss of entire bird species from possible global warming. Recorded deaths of birds of prey and other birds in wind farms in the United States currently amount to no more than 300 per year. By contrast, in the United States an estimated 97 million birds are killed each year when they collide with buildings made of plate glass, 57 million are killed on highways each year。 and millions of birds are electrocuted each year by transmission and distribution lines carrying power produced by nuclear and coal power plants.
