That land would be far better left alone2, he says. Renewables look attractive when they are quite 2 . But if we start producing renewable energy on a large scale, the fallout is going to be horrible. Instead, Ausubel argues 3 renewed 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 will 4 as the best land for wind, biofuels, and solar power gets used up. Using biofuels to obtain the 5 amount of energy as a 1000 megawatt nuclear power plant would require 2500 square kilometres of farm 6 , Ausubel says. "We should be sparing land for nature5, not using it as pasture for cars and trucks," he adds. 来源:中国职称英语考试网 Solar power is much more efficient than biofuel in terms of the area of land 7 , but it would still require 150 square kilometres of photovoltaic cells to 8 the 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 critical 9 Ausubel’s conclusions. John Turner of the US government’s National Renewable Energy Laboratory says that 10 the 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 not 11 additional land. The US could get a quarter of its energy just from covering rooftops of 12 buildings, 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 it 13 . Farmers can still farm the land that the turbines are on8. Turner says looking solely at land use is an oversimplification of the 14 . "I’m not sure I’d want to build one of these nuclear plants in Afghanistan9, but we could 15 put in wind and solar power," he adds. 来源:中国职称英语考试网 练习: 1. A) figures B) amounts C) numbers D) digits 2. A) small B) huge C) little D) vast 3.A) at B) over C) for D) against 4.A) expand B) minimize C) enlarge D) decrease 5.A) same B) similar C) alike D) identical 标准答案:B,A,C,D,A 来源:中国职称英语考试网 解析:1.B虽然四个选项的词 (figures 数字, 体形,考虑(figure out计算出/断定), amounts 数量, 总计,numbers 数目,digits 阿拉伯数字) 都是与数字有关的,在vast... of修饰不可数名词 land ,因此需要用 amounts。B 是答案。 2.A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。 考点:上下文之间的意义。 3.CAusubel 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 for...(争论以支持...)。 argue over (就……进行争论), argue against (争论以反对...) 都不符合上下文的意思。. 来源:中国职称英语考试网 4.D“空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.A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。 25、 6. A) region B) site C) area D) land 7.A) leased B) cultivated C) used D) purchased 8.A) patch B) match C) catch D) fetch 9. A) in B) with C) of D) on 10. A) even if B) only if C) what if D) as if 标准答案:D,C,B,C,A 来源:中国职称英语考试网 解 析:6.DLand在前文中出现过, 因此land成为答案的可能性较大。Region 和area词义十分接近, 可以彼此排除掉, B出现在空格中不合适。 Farm land的含义为耕地。 7.C“空7”所在的句子的意思是: 根据...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.B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.Ccritical 要求后接 of。C 是答案。 来源:中国职称英语考试网 10.A从“空10”所在的句子分析:the US got all of its power from solar energy 应该是宾语从句中的让步状语从句,选 A 的 even if 是对的。only if (只有当...)、what if (如果……怎么办)、as if (仿佛)从其分别得使用特点上看都不能出现在空格处。 26、 11.A) lock up B) take up C) give up D) step up 12.A) towering B) interesting C) nicelooking D) existing 13.A) surrounds B) contains C) includes D) covers 14.A) issue B) stuff C) summary D) suggestion 15.A) doubtfully B) supposedly C) certainly D) honestly 标准答案:B,D,D,A,C 来源:中国职称英语考试网 解 析:11.B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 (逐步增加) 的意思与上下文不匹配。 12.D“空12”所在的句子的意思是: 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.D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)。第三句说建有涡轮 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.A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 、summary 、suggestion 都不对。 来源:中国职称英语考试网 15.C“空15”所在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。 [ ]查看更多1个回答 . 3人已关注
翻译遇到的问题? In this sensitized TiO2, charge injction from the CB of the narrowband gap semiconductor to that of TiO2, which reduces the recombination of electron and hole, leads to efficient and longer charge separation.语法没学好啊,就是理不顺,来求帮组。 查看更多1个回答 . 3人已关注
