【正确答案】 B

【答案解析】[听力原文] 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. [分析] 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砌寸线，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。 [解题关键] 正确理解句子结构。

【正确答案】 A

【答案解析】[听力原文] 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. [分析] 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。 [解题关键] 掌握表因果关系的信号词，如文中“not caused...”，“because...”等。

【正确答案】 B

【答案解析】[听力原文] 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. [分析] 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 pre existing 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。 [解题关键] 掌握同义词的替换。如文中preexisting idea与题干中preconception同义。

【正确答案】 B

【答案解析】[听力原文] 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. [分析] 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。 [解题关键] 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。

【正确答案】 A

【答案解析】[听力原文] 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. [分析] 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。 [解题关键] 同义词替换。本题需掌握porcine与题干中pig同义。
