【正确答案】 B

【答案解析】[听力原文] In any movie theater any summer, you can practically hear the atrophying of brain cells. Summer pictures don't insult the audience's intelligence so much as they ignore it, playing instead to the mass-market inner child. But with most big films serving as a form of pop-cultural potty training, there's a grand void to be filled for viewers who have not sent their brains to summer camp—who want the occasional film to speak to their inner grownup. [分析] 观点态度的判断。 根据原文可知夏季影片会带来“the atrophying of brain cells”即“脑细胞的萎缩”；而且最后一句表明观众心声时说“viewers who have not sent their brains to summer camp—who want the occasional film to speak to their inner grownup"即“看夏季电影并不用费脑子，可观众有时也想看看那些能引起内心思考的影片”，由此可见，选项B的说法与原文相符，因此，该项答案是正确的。 [解题关键] 理解关键短语背后的含义并由此对文章的观点作出判断是解题的关键，如理解原文中两处表示委婉的否定态度的说法：the atrophying of brain cells和want…to speak to their inner grownup。

【正确答案】 C

【答案解析】[听力原文] Political tourism first took off in the 1980s, when activists, angry at the United States for propping up Central American dictators, began flocking to countries like Nicaragua and Honduras to see the result themselves. Groups such as the London-based Nicaragua Solidarity Network were only too happy to accommodate them. After returning home, activist tourists tended to take like-minded compatriots back to the region to express solidarity with a movement, act as international observers or simply educate foreigners on the consequences of cold-war policies. [分析] 主旨题。 原文第一句提出“Political tourism first took off in the 1980s…”而后面的各句都是支持性细节，分别从原因、状况和结果等方面进一步介绍说明这种新兴的旅游形式。因此，恰当概括原文中心思想的选项C的内容是正确的。 [解题关键] 正确识别中心句与支持性细节的关系。

【正确答案】 A

【答案解析】[听力原文] Human cloning involves creating an embryo out of a cell taken from a fully developed human being. "Reproductive" cloning means growing an embryo into a second, genetically identical human being. "Therapeutic" cloning, by contrast, means using an embryo as a source of stem cells for the person who supplied the originally cell. The theory is that stem cells with DNA identical to yours would be more likely to develop successfully into replacement parts for you. Brain cells for people with Parkinson's are the most promising example, but ultimately even severed limbs might grow back this way. [分析] 语义的判断和推理。 原文讨论的主题是therapeutic cloning(用于治疗的克隆技术)，根据原文可知克隆可用于繁殖和治疗，用于治疗的克隆细胞可作为stem cells(干细胞)，由于它与原供应体的DNA一样，所以可以成功用于原供应体的移植。克隆技术对帕金森症的治疗有广阔的前景。由此可见，只有选项A的说法与原文不符，因此，该选项是正确答案。 [解题关键] 抓住原文中的关键词作出正确的推断，如therapeutic(治疗的)与选项A中research(研究)意思相左。

【正确答案】 B

【答案解析】[听力原文] The disappointing ministerial conference that concluded in Cancun, Mexico in September will have many ramifications, but sadly the most significant of them will be its impact on poor countries. A more open and equitable trading system would provide them with an important tool in alleviating poverty and raising their levels of economic development. [分析] 语义理解判断。 原文第一句提到Cancun部长会议结果颇多，但其中最重要的是对贫困国家产生的影响。接着在第二句点明更开放更公平的贸易制度将对这些国家产生巨大帮助。由此可推测，更开放更公平的贸易制度应该是这次会议的议题。因此，选项B的内容与原文相符，是正确的。 [解题关键] 正确推断主题是本题的关键。

【正确答案】 D

【答案解析】[听力原文] It takes only a trip on the busy but rutted highway that leads north from here to understand how a huge swath of the Amazon jungle could have been razed over the course of just a year. Where the jungle once offered shelter to jaguars, parrots and deer, the land is now increasingly being cleared for soybeans, Brazil's hottest cash crop. [分析] 语义判断推理。 原文描述了亚马逊热带雨林一年来经历的巨大变化。最后一句具体指出这片土地曾经是各种动物的栖息地，而现在却被大量开垦用来种植经济作物。从我们对环境保护的背景知识可推测，这种变化应该是破坏性的。由此可知，选项D的内容与原文意义相符，因而是正确的。 [解题关键] 对环境保护的背景知识有助于正确解题。
