【答案解析】[听力原文] Today, I ask you to focus on the challenges of the Information Age. The dimensions of the Information Revolution and its limitless possibilities are widely accepted and generally understood, even by lay people. But to make the most of it, we must acknowledge that there are challenges, and we must make important choices. We can extend opportunity to all Americans or leave many behind. We can accelerate the most powerful engine of growth and prosperity the world has ever known, or allow the engine to stall. [分析] 主旨题。 原文首句点明该段主题Today，I ask you to focus on the challenges of the Information Age，而后具体说明了信息时代挑战的主要内容。由此可知，选项B的内容与原文相符，因此是正确答案。 [解题关键] 1)注意提示主旨的词语，如首句中focus on明确了其后内容即为全段主旨内容；2)注意段落行进的方式。本段首先提出普遍认同的观点，而后使用信号词 but，提示听者注意后面的内容是说者讨论的重点内容，应为全段主旨。因此对于类似段落，听者应注意段中表转折的词语后面的内容。

【正确答案】 B

【答案解析】[听力原文] The teaching of English to speakers of other languages (TESOL) is an area in which Australia is internationally recognized to have developed considerable and particular expertise. So, too, in the teaching of the teachers, Australia has a strong reputation for the high quality of its pre-service and in-service training of English language teachers. My department, and particularly a subsidiary within it, Australian Education International, share a conviction that this expertise is of value to our overseas colleagues, many of whom have responsibility for developing TESOL in their own countries. [分析] 推理判断题。 根据原文相关信息My department, and particularly a subsidiary within it, Australian Education International, share a conviction that this expertise is of value to our overseas colleagues 即我所在的系——特别是系内的澳大利亚国际教育学院都坚定地认为这样的专门技能对于我们的海外同事来说是有价值的，由句中单词和短语my department及 colleagues可推断，A项和C项可排除；又根据上句中对该系的说明particularly a subsidiary within it,由it的指代关系可知，该系主要关于training of English language teachers，这样，选项D也被排除。由此可知，选项B是正确答案。 [解题关键] 1)根据题干要求，有重点地在原文中找寻与之有关的信息，并作简单的推理判断；2)掌握代词的指代关系，有助于听者正确理解原文内容，作出正确推断。

【答案解析】[听力原文] Laughter can even provide a kind of pain relief. Scientists had proved that laughter produces endorphins -- chemicals in the body that relieve pain. They divided 40 university students into four groups. The first group listened to a funny cassette for 20 minutes. The other three groups listened to either an informative tape, or a cassette intended to relax them, or no tape at all. Scientists found that if they produce pain in the students, those who had listened to the humorous tape could tolerate the discomfort for much longer. [分析] 主旨题。 本段开宗明义说Laughter can even provide a kind of pain relief 即开怀大笑可以缓解疼痛，然后以科学实验作为支持性细节，最后以实验结果强调了本段结论Scientists found that if they produce pain in the students，those who had listened to the humorous tape could tolerate the discomfort for much longer 即科学家发现如果他们对学生们施以疼痛，那些听过幽默故事磁带的学生忍受疼痛的时间更长些。由此可见，选项C的内容与原文意思相符，因此是正确答案。 [解题关键] 着重掌握对段落首尾句的理解。段落首句往往点明本段主题，而尾句往往是结论句，概括全段主要内容。

【正确答案】 C

【答案解析】[听力原文] The average life of a hurricane is only about nine days, but it contains almost more power than we can imagine. The energy in the heat released by a hurricane's rainfall in a single day would satisfy the entire electrical needs of the United States for more than six months. Water, not wind, is the main source of death and destruction in a hurricane. A typical hurricane brings 6-to 12-inch downpour resulting in sudden floods. Worst of all is the powerful movement of the sea -- the mountains of water moving toward the low-pressure hurricane center. The water level rises as much as 15 feet above normal as it moves toward shore. [分析] 事实细节的找寻和判断。 根据题干中的关键词可定位到原文相关信息Water，not wind, is the main source of death and destruction in a hurricane 造成飓风中人员死亡、财产遭受破坏的因素是水而不是风。由此可见，C项与原文意思相符，因此是正确答案。 [解题关键] 能够根据题干关键词正确定位原文相关信息。

【正确答案】 B

【答案解析】[听力原文] Of course, concerns about deflation and slow growth are closely interlinked. If the American economy were to slide into deflation, with prices actually falling, hopes for a sustained economic recovery would be dashed. Once prices start to fall, consumers and businesses postpone all but the most essential purchases. What is the point of buying something now if it will be cheaper in a few months' time? It is easy to see how quickly the economy could slide back towards recession. Japan, in or close to recession for much of the past decade, is now experiencing its fourth consecutive year of falling prices. [分析] 事实细节的找寻和判断。 根据题干中关键词Japan可定位到相关信息Japan，in or close to recession for much of the past decade, is now experiencing its fourth consecutive year of falling prices. 由其中的the past decade“过去10年”可知，日本已遭受了十年的经济衰退。由此可见，选项B的内容与原文相符，因此是正确答案。 [解题关键] 1)根据题干中关键词正确定位到原文相关信息；2)掌握同义词替换，选项B中ten years与原文decade是同义词。
