【正文】 　　7. The phrase this problem in the passage refers to　　○Interference with the flight patterns of migrating birds in certain areas　　○B(yǎng)uilding ridge lines that are ideal for wind turbines　　○The killing of birds of prey by wind turbines　　○Meeting the demands of environmentalists who promote renewable wind energy　　8. Which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.　　○Hawks, falcons, and eagles prefer to hunt along ridge lines, where wind turbines can kill large numbers of migratory birds.　　○Wind turbines occasionally cause migratory birds to change their flight patterns and therefore may interfere with the areas where birds of prey prefer to hunt.　　○Some of the best locations for large wind farms are places that may cause problems for migrating birds and birds of prey.　　○Large wind farms in certain areas kill hawks, falcons, and eagles and thus might create a more ideal path for the flight of migratory birds.　　9. In paragraph 5, why does the author give details about the estimated numbers of birds killed each year?　　○To argue that wind farms should not be built along ridge lines　　○To point out that the deaths of migratory birds exceed the deaths of birds of prey　　○To explain why some environmentalists oppose wind energy　　○To suggest that wind turbines result in relatively few bird deaths　　10. The phrase amount to in the passage is closest in meaning to　　○Can identify　　○Change　　○Are reduced by　　○Total　　Paragraph 6: The technology is in place for a major expansion of wind power worldwide. Wind power is a virtually unlimited source of energy at favorable sites, and even excluding environmentally sensitive areas, the global potential of wind power is much higher than the current world electricity use. In theory, Argentina, Canada, Chile, China, Russia, and the United Kingdom could use wind to meet all of their energy needs. Wind power experts project that by the middle of the twentyfirst century wind power could supply more than 10 percent of the world’s electricity and 1025 percent of the electricity used in the United States.　　11. The word project in the passage is closest in meaning to　　○Estimate　　○Respond　　○Argue　　○Plan　　12. Which of the following statements most accurately reflects the author’s opinion about wind energy?　　○Wind energy production should be limited to large wind farms.　　○The advantages of wind energy outweigh the disadvantages.　　○The technology to make wind energy safe and efficient will not be ready until the middle of the twentyfirst century.　　○Wind energy will eventually supply many countries with most of their electricity.　　Paragraph 1: Since 1980, the use of wind to produce electricity has been growing rapidly.　　█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. █　　13. Look at the four squares █that indicate where the following sentence could be added to the passage.　　Some panies in the power industry are aware of this wider possibility and are planning sizable windfarm projects in states other than California.　　Where would the sentence best fit?　　Click on a square █to add the sentence to the passage.　　14. Directions: An introductory sentence for a brief summary of the passage is provided below. Complete the summary by selecting the THREE answer choices that express the most important ideas in the passage. Some sentences do not belong in the summary because they express ideas that are not presented in the passage or are minor ideas in the passage. This question is worth 2 points.　　In the future, wind power is likely to bee a major source of the world’s energy supply.　　Answer Choices　　○Wind farms have already produced sufficient amounts of electricity to suggest that wind power could bee an important source of electric power.　　○Wind power has several advantages, such as low pollution and projected cost declines, pared to other energy sources.　　○Responding to environmentalists concerned about birds killed by wind turbines, analysts point to other human developments that are even more dangerous to birds.　　○The wind energy produced by just a small number of states could supply all of the power needs of the United States.　　○Although wind power is not economical in areas with steady winds, alternative wind sources can be used to simulate wind power.　　○Smaller countries, which use less electricity than large countries, are especially suited to use wind power to meet all their energy needs.　　Drag your answer choices to the spaces where they belong.
