The wavelengths of light and radio waves, unlike high energy gamma radiation, are much shorter.
【正确答案】
B
【答案解析】 Nuclear energy is released at the sun's center as high energy gamma radiation, a form of electromagnetic radiation like light and radio waves, only of very much shorter wavelength.比较结构的理解。本题要求听者分辨清所比较之物及其对比关系。原文谈到Nuclear energy(核能)时,将其解释为high energy gamma radiation(高能伽马辐射),像光波和无线电波一样属于一种光磁射线,只是其波长更短一些。由此可见,题干说光波和无线电波的波长短得多的说法是错误的。 注意:正确理解句子结构。

The speaker believes that a practical solution to the problem of starvation is to remove obstacles to adequate supply of food rather than to increase production of it.
【正确答案】
A
【答案解析】 Hunger is not caused by a global scarcity of food. The world can easily produce enough to feed everyone, without any government support. When people go hungry, it is because they do not have access to food — sometimes for reasons of war or politics, most often because of poverty.因果关系判断。关于饥谨问题,文章认为“Hunger is not caused by a global scarcity of food”即“饥饿不是由于全球粮食匮乏造成的”,而且进一步说“…it is because they do not have access to food——sometimes for reasons of war or politics,most often because of poverty”即“饥饿问题是因为人们由于战争、政治、贫穷等原因而无法得到食物”,显然文章认为饥谨问题与粮食供应的畅通与否有关。因此,题干说解决饥谨问题需要消除粮食供应的障碍而非提高粮食产量的说法是正确的。 注意:掌握表因果关系的信号词,如文中“not caused…”,“because…”等。

According to the speaker, it is foolish and childish for a filmmaker to mix his preconceptions with objective truth when he produces a documentary.
【正确答案】
B
【答案解析】 A documentary is an arrangement of non-fictional films, structured to support the preexisting ideas of the filmmaker. Only the terminally stupid and the childishly innocent imagine that anyone making a documentary film aspires to objective truth.观点态度的找寻和判断。关于documentary(记录片),文章认为这种影片“structured to support the preexisting ideas of the filmmaker”即“就是要迎合支持制片商的先入之见”,文章还认为只有愚蠢、幼稚的制片商才会使记录片“…aspires to objective truth”即 “追求客观事实”。由此可见,题干认为记录片是制片商“mix his preconceptions with objective truth”即“将其先入之见和客观事实融合”的说法与原文不符,因此是错误的。 注意:掌握同义词的替换。如文中preexisting idea与题干中preconception同义。

In Japanese party politics, the Liberal Democrats are more prone to stand by their principles than their conservative and nationalist counterparts.
【正确答案】
B
【答案解析】 Too often, Japan's conservative and nationalist leaders have managed to spot the forces of change more quickly than their liberal domestic counterparts, and have used those changes to seize the advantages and preserve their power.比较结构的理解。本题要求将conservative and nationalist leaders和liberal democrats的政治立场进行比较。根据原文“Japan's conservative and nationalist leaders have managed to spot the forces of change more quickly than their liberal domestic counterparts”即“日本保守党和民族主义者比自民党更能发现变化的力量”,由此可知,自民党不能很快地发现变化的力量,但与题干所言自由民主党更倾向于遵守其原则含义不相符,因此题干的说法是错误的。 注意:掌握词语的概念。the forces of change(变化的力量)的概念与principles(原则)不相同。

The author believes that, given the similarities between pig and human organs, future technology will allow pig livers to be transplanted to humans.
【正确答案】
A
【答案解析】 As a super hero in her own right, Xena is a female piglet cloned from fetal-pig skin cells. She may prove to be more than the latest addition to the biotech clone farm. Because of similarities between porcine and human organs, the techniques that made Xena may eventually create a supply of genetically modified pig livers that would be acceptable to the human immune system.语义逻辑推理判断。原文认为“Because of similarities between porcine and human organs,the techniques that made Xena may eventually create a supply of genetically modified pig livers that would be acceptable to the human immune system.”即“鉴于猪和人的器官有相似性,创造了Xena的技术必将创造出可以为人类免疫系统接受的转基因猪肝脏”,由此可推断由于猪和人内脏器官有相似性,未来技术将会使得猪的肝脏移植到人身上。因此,题干的说法是正确的。 注意:同义词替换。本题需掌握porcine与题干中pig同义。

Bioinformatics is a new computer software technology that makes research findings on genetic engineering publicly available to the public.
【正确答案】
A
【答案解析】 Bioinformatics is the name given to the computer software technologies that are being devised to manage information overload. The field includes everything from storage to classification, analysis and distribution of gene and protein sequence data. Bioinformatics tools have moved genetic research out of the laboratory and transferred it to computer databases for use by anyone with access to the Internet.定义及细节的理解。通过原文定义可知bioinformatics是一种计算机软件技术,其特点之一是“move genetic research out of the laboratory and transferred it to computer databases for use by anyone with access to the Internet”即“将基因研究搬出实验室,将其转移到计算机数据库,可以让能够上网的任何人使用”,由此可见,题干的说法是正确的。 注意:1)掌握英语定义结构特点,即先归类后指出主要特点;2)掌握词组with access to的含义。

Imports from Asian countries are more competitive than U.S. home-made products because of lower wages in Asia and the exemption of duties for imported goods shipped to the United States.
【正确答案】
B
【答案解析】 Foreign laborers, especially Asian ones earning low wages, are pictured as working willingly for American capitalists abroad who pay slightly better than average wages; while the former learn otherwise inaccessible technology and produce sophisticated goods that compete with domestic American goods, even allowing for shipping charges and import duties.语义逻辑推理判断。根据原文可知,对于美国海外资本家来说使用外国劳力,尤其是亚洲国家的劳力费用非常低。而这些国家却从此得到先进技术,生产尖端产品。这些产品,即使在增加运费和进口税的水平上仍可与美国国内制造的产品竞争。由此可见海外美国人使用亚洲劳力制造的产品,即使有运费和进口税的压力,仍然可与美国本土制造的产品竞争。显然这与题干中所言进口美国的商品免除税费的说法不相符。因此,题干的说法是错误的。 注意:掌握短语含义。原文中“allowing for…”意为“将……计算在内”,而题干中“the exemption of”意为“免除”,二者含义正好相反。

States should respect international law even if some people are skeptical about its power to be enacted.
【正确答案】
A
【答案解析】 It is significant that those who regard international law as a form of morality usually speak of it as "mere morality". Although experienced diplomats do not often share the popular skepticism about international law, there is a danger that the popular attitude may affect inexperienced officials and pressure groups within a state, and that the state may, as a result, be pushed into breaking international law.因果关系的理解和推断。原文认为公众对国际法的怀疑态度会影响国内那些经验尚不丰富的官员和重要的集团,其结果便是,这种怀疑态度会导致违反国际法。由此可推断,即使一些人对国际法持怀疑态度,国家要尊重该法,才能使国际法得以贯彻实施。显然,题干的含义符合对原文的推断,因此,该题的说法是正确的。 注意:注意识别表因果关系的信号词,以便正确理解因果关系。原文中使用了“as a result”。

The international community should seek other effective methods in establishing economic global governance instead of relying on the WTO.
【正确答案】
B
【答案解析】 Asking for a WTO focused on its trade mission is not to neglect the importance of the other problems the institution has been asked to deal with. But the balance that many countries expect to see in the economic global governance agenda should not be pursued solely at the WTO. The international community should create effective ad-hoc instruments to confront the other challenges.语义逻辑关系的理解和判断。原文最后部分指出国际共同体应该“create effective ad—hoc instruments to confront the other challenges”即“创造有效、特别的方法面对其他挑战”,而题干中却说国际共同体寻求有效的方法是为了“in establishing economic global governance…”即“建立经济的全球管理方式……”,显然题干所言的目的与原文不相符,因此,该题的说法是错误的。 注意:掌握表示目的的信号词,有助于快速理解语义。原文中信号词为最后一句中动词不定式短语;而题目中为介词in短语。
单选题
Economists attribute the world soybean boom to the rise in soybean production in China and its increased export of related products.
【正确答案】
B
【答案解析】 Economists say that the main spur to the global soybean boom is the emergence of a middle class in China, much of whose newly disposable income has been spent on a richer, more varied diet. Over the past decade, China has been transformed from a net exporter of soybeans to the world's largest importer in some years of whole soybeans as well as oil and meal byproducts.因果关系的理解和判断。根据原文,文中把全球大豆畅销的原因归结为“the emergence of a middle class in China”即“中国中产阶级的出现”,而题干中却将其原因归结为“the rise in soybean production in China and its increased export of related products”即“中国大豆产量的增加和相关产品出口的增加”,显然该说法与原文不符,因此,该题的说法是错误的。 注意:掌握表因果关系的信号词,可以帮助听者做出正确的判断。原文第一句使用系表结构,直截了当说明原因。题干使用了短语attribute to(归因于)。
