共享题干题 (一)Debate over the Use of Renewable Energy根据以下材料，回答问题。 Ausubel of Rockefeller University in New York, US says the key renewable (可再生的) energy sources, including sun, wind and bio-fuels, would all require vast amounts of land if developed up to large scale production--unlike nuclear power. That land would be far better ___________ (51) alone,he says. Renewable look ___________ (52) when they are quite small. But if we start producing renewable energy on a large ___________ (53), the fallout (结果) is going to be horrible. Ausubel draws his conclusions by analyzing the amount of energy that renewable, natural gas and nuclei (原子核) can ___________ (54) in terms of power per square meter of land used.Moreover, he claims that ___________ (55) renewable energy use increases, this measure of efficiency will decrease as the best land for wind, bio-fuels, and solar power gets used up. Solar power is much more ___________ (56) than bio-fuel in terms of the area of land used,but it would still ___________ (57) 150 square kilometers ofphotovoltaic (光电的 ) cells to match the energy production of the 1,000 MW nuclear plant. In another example, he s'ays___________ (58) the 2005 US electricity demand via wind power alone would need 780,000 square kilometers,an area the ___________ (59) of Texas. However, several experts are highly critical of Ausubel's ___________ (60). John Turner of the US government's National Renewable Energy Laboratory says that even if the US got all of its ___________ (61) from solar energy, it would still need less than half the amount of land that has been paved over ___________ (62) highways, Further, it need not ___________ (63) up additional land. The US could get a quarter of its energy just from covering rooftops of existing buildings, he says. According to Turner, the same "dual use" also ___________ (64) to wind power. "The footprint for wind is only 5% of the land that it ___________ (65). Farmers can still farm the land that the turbines are on." Turner says looking solely at land use is an oversimplification of the issue.1.[不定向选择题]____________A.to B.in C.on D.for 2.[不定向选择题]____________A.decisions B.conclusions C.solutions D.modifications

1.参考答案：D
参考解析：for在此处表示用途，表示用于修建高速公路的土地。to，in，on都不表示“用途”。
2.参考答案：B
参考解析：从上下文语境来看，很多专家却批评了Ausubel的结论。decisions表示“决定”，solutions表示“解决途径”，modifications表示“更改，修正”。Ausubel只是能源问题的研究者，而非决策者，所以A、C、D都不合适。3.[不定向选择题]____________A.scale B.number C.part D.extent

这个答案应该是对的
