【正确答案】 B

【答案解析】[解析] John Ciardi was horn in 1916 in Boston, Massachusetts, the child of Italian immigrants. He attended Bates College and Tufts College and received his master's degree from the University of Michigan in 1939. He is the author of more than forty volumes of poetry. [分析] 事实细节的找寻和判断。 将题干中的细节信息与原文对照，发现原文说John Ciardi写诗的数量为“more than forty volumes of poetry”即“四十多卷诗歌”，而不是题干所言的四十多首(more than forty poems)。因此，该题的说法是错误的。 [解题关键] 注意数字后面的量词。量词经常会成为听力考查的对象。

【正确答案】 A

【答案解析】[解析] Most NASA spacecraft rely on some form of chemical propellant to push themselves through space. But at the Marshall-based center, researchers are studying a range of future propulsion methods, including propellant-less systems, simulated fission engines that could one-day lead to the real thing and the basic technologies necessary for future antimatter drives. [分析] 语义推断题。 该段主要讨论宇宙飞船的动力系统。根据原文我们知道如今大部分飞船靠化学物质作为动力，但如今研究者们正在研制一系列的未来动力措施。由此可推测，未来飞船不会使用化学物质作为动力。因此，该题的说法是正确的。 [解题关键] 注意文中信号词的使用。文中第二句使用but实现了前后部分的转折，前部分说飞船使用化学推动力，自然该词后部分应该是说飞船不再会使用化学物质为动力。

【正确答案】 A

【答案解析】[解析] I just got out of a history class. I'm sure I made a fool of myself. I just got so embarrassed and nervous whenever I've to speak in front of a group of people. I stand up and my face gets red and then I get even more nervous because I know everyone can see me blushing. [分析] 语篇逻辑结构的判断。 原文是说话者谈自己上历史课的表现。中心词使用了embarrassed and nervous，后面以具体事例说明他是如何embarrassed and nervous。因此题目总结他的表现是embarrassed与原文相符，是正确的说法。 [解题关键] 判断中心句和支持性细节的关系。一般而言，中心句的用词较为抽象、具有概括性，如文中所用的embarrassed，而支持性细节的用词较为生动具体，如文中的具体事例。

【正确答案】 B

【答案解析】[解析] The company, which was not the sole source of the pollution but is the only business working on the cleanup, has already spent several million dollars installing ventilation systems and creating a network of wells, pumps and filters to extract chemical contaminants from groundwater. The vapor problem came to light in 2003 as a result of air-quality tests sought by residents. [分析] 事实细节的找寻和判断。 根据文章语义因果关系可推断地下水中的污染物蒸发造成空气污染，这一点与题干说法相符，但就地下水的来源，通过原文“the company, which was not the sole source of the pollution”可推测，被污染的地下水并非只来自该公司一家，因此，该题的说法是错误的。 [解题关键] 对关键词的正确理解有助于解题，如原文相关处一词“sole”意为“唯一的”，可帮助听者推测既然该公司不是唯一的污染源，那么被污染的地下水就不会只来自该公司一家。

【正确答案】 A

【答案解析】[解析] Faced with a problem that could break the budget, Maryland is joining a growing number of states by looking for private partners to help improve school facilities. A law that took effect July 1 allows Maryland’s school systems to fund school construction and renovation projects using alternatives to traditional financing, which usually comes from the sale of bonds by public agencies to banks and investors. [分析] 特定信息的找寻和判断。 根据题干中提供的特定信息Maryland，school和construction and renovation，找到原文相关处，可知“A law... allows Maryland's school systems to fund school construction and renovation projects using alternatives to traditional financing, which usually comes from the sale of bonds...”即“该法规允许马里兰州的学校使用非传统的方式解决其用于校舍建设和翻新的资金，比如可以出售债券”，由此可见，该题的说法是正确的。 [解题关键] 搞清句子成分有助于解题，如原句说到解决资金使用非传统手段时，使用了which引导的非限定性定语从句，具体说明了bonds这一形式。
