Question

Ausubel of Rockefeller University in New York, US. says the key renewable energy sources, including sun, wind and biofuels, would all require vast1of land if developed up to large scale production¹ – unlike nuclear power. That land would be far better left alone², he says. Renewables look attractive when they are quite2. But if we start producing renewable energy on a large scale, the fallout is going to be horrible. Instead, Ausubel argues3renewed development of nuclear.
Ausubel draws his conclusions by analysing the amount of energy renewables, natural gas and nuclear can produce in terms of power per square metre of land used³. Moreover, he claims that as renewable energy use increases, this measure of efficiency⁴ will4as the best land for wind, biofuels, and solar power gets used up.
Using biofuels to obtain the5amount of energy as a 1000 megawatt nuclear power plant would require 2500 square kilometres of farm6, Ausubel says. "We should be sparing land for nature⁵, not using it as pasture for cars and trucks," he adds.
Solar power is much more efficient than biofuel in terms of the area of land7, but it would still require 150 square kilometres of photovoltaic cells to8the energy production of the 1000 MW nuclear plant. In another example, he says meeting the 2005 US electricity demand via wind power alone would need 780,000 square kilometres, an area the size of Texas.
However, several experts are highly critical9Ausubel’s conclusions. John Turner of the US government’s National Renewable Energy Laboratory says that10the US got all of its power from solar energy, it would still need less than half the amount of land that has been paved over for highways. Further, it need not11additional land. The US could get a quarter of its energy just from covering rooftops of12buildings, he says.
According to Turner, the same "dual use" also applies to wind power⁶. "The footprint for wind⁷ is only 5% of the land that it13. Farmers can still farm the land that the turbines are on⁸. Turner says looking solely at land use is an oversimplification of the14. "I’m not sure I’d want to build one of these nuclear plants in Afghanistan⁹, but we could15put in wind and solar power," he adds.

1.虽然四个选项的词（figures 数字， amounts 数量，numbers 数目，digits 数码）都是与数字有关的，在 of land 之前，要用 amounts.B 是答案。
2.在 "Renewables look attractive when they are quite     ?   . But if we start
producing renewable energy on a large scale, the fallout is going to be horrible"这两个句子之间，
有个连词 But, 说明两个句子的意思相反。后一句说，如果大规模开发可再生能源，其后果
十分可怕。既然 "大规模"、"可怕"，前一句填入空格的词应该与之相反。选项 A 是 small，
正符合要求，A 是答案。
3.Ausubel 是不赞成大规模开发可再生能源的。"空3"后出现 nuclear, 可以合理地推论出，这是他赞同的能源。所以要选 C 的for.argue by （通过……进行争论）, argue over （就……进行争论）, argue against （争论以反对）都不符合上下文的意思。
4.前面一句说，Ausubel 对可再生能源、天然气和核电厂发出的电量与其占用土地
的量的比值作一比较。"空4"所在的句子说，随着风力发电、生物燃料发电和太阳能发电占
用的最好的土地逐渐用完，这个效率比值会发生什么变化呢？从 gets used up 分析，效率
比值应该变小才对。所以要选 D的 decrease.minimize （使最小化）不符合上下文的意思。
5.从句子的意思和词的搭配上看，填入 "空5"的词是选项 A 的 same.same…as 是
固定搭配。填入 same 之后，句子的意思也完整了，即：用生物燃料得到与 1000 兆瓦核
电厂相同的能量需要 2500 平方公里的耕地。
6.前文说的效率比值都是以 land 为标尺，所以这儿要选 A 的  land.
7.句子的意思是：按     ?   土地计算，太阳能的效率比生物燃料的效率高得多 .最适合填入的词是 C 的 used.其它三个选项 leased （租借）、cultivated （耕种）、purchased （购买）都不符合上下文的意思.
8.本题只能选 B 的 match （相匹配），其它三个选项，即 patch （补缀）、catch （捕捉）、fetch （取来）只是与 match 发音接近，意思与上下文不匹配。
9.critical 要求后接 of.C 是答案
10.John Turner 是反对 Ausubel 的计算方法的。从"空10"所在的句子分析， the US got all of its power from solar energy 应该是一个让步状语从句，选 A 的 even if 是对的。此外，only if （决不……除非）、what if （如果……怎么办）、as if （仿佛）的意思都与上下文搭不上，也佐证了选 A 是正确的。
11.本题只能选 B 的 take up （占用），因为用上 take up 后，上下文的意思就连贯了。其它三个选项，即 lock up（锁上）、give up （放弃）、step up （加紧）的意思与上下文不匹配。
12.句子的意思是：美国仅仅从     ?    大楼的楼顶（铺设的太阳能电池板）
中就能得到四分之一的能量。从意思连贯的角度选择，选项 D 的 existing 最符合题意。
13.本段第一句用了 "dual use".第二句说风力发电占用土地的百分数（土地的第一
个用途）。第二句说建有涡轮发电机的土地仍然可以用于耕种（土地的第二个用途）。"空
13"要填的动词应该是 D 的 covers （覆盖）。the land that it （指代 wind） covers, 意为 "
风力发电所覆盖的土地".
14.an oversimplification of the     ？   ，究竟对什么过度简单化呢? 从上下文看，应该是对占用土地问题的过度简单化。选项 A 的 issue （问题）正是上下文缺失的词。stuff （材料）、summary （总结）、suggestion （建议）都不对。
15.句子的前半句是说不会在阿富汗建造核电站，后半句用 but 开始，说明前半句和后半句的意思相反。前半句用了 I'm not sure，后半句用选项 C 的 certainly, 与 not sure 的意思相反，是很合理的。
