【真题来源：2012年12月大学英语四级真题（第二套）Part Ⅳ，Section B，第62-66题】
Are people suffering form gadget (小器具) overload? Are they exhausted by the consumer equivalent of the brain fatigue — information overload — that is caused by constant updates of devices and online media?
Underwriters Laboratories issued a report last week that found 48% of consumers “feel high-tech manufacturers bring new products to market faster than people need them.”
There are two possible explanations. The first, obvious one is that the pace of innovation (创新) is too fast for consumers. The second, less obvious one is that, innovation is too slow. That is the new offerings companies are pushing out the door every six months or so are me-too products or ones with just a couple of new features. Marketing schedules, not product innovation, are driving the corporate ( 公司的 ) train. Manufacturers in American valued “spend to market” more than in other countries, the report found.
Sara Greenstein, Underwriters Laboratories' chief strategy officer, offered her interpretation of the survey results, “Innovation is too fast only if corners are cut.”
For the high-tech sector, there are a few other interesting finding. Consumers are less concerned about safety in high-tech products than categories like fresh and processed food. But their top safety concerns are emissions and wireless radio waves. Many people, it seems, are uneasy living in a thickening cloud of radio waves from mobile phone towers and the gadgets they communicate with.
A finding that was a bit surprising is that to consumers, the inner parts of high-tech devices do apparently matter. Some 55% of consumers, according to the report, said they are “more” concerned about high-tech components come from than where the product was assembled.”
The report doesn't really say how that information would affect consumer buying decisions. It could be complicated. Manufacturing companies on average rely on more than 35 contract suppliers around the world to create a single product. That number would be higher for a smartphone or laptop.
But maybe some sort of supply-chain labeling showing where parts come from in a product? “We're working on it,” Ms. Greenstein said.
What is the finding in Underwriters Laboratories' report about many consumers?
【定位】 由题干中的 finding 和 Underwriters Labomtories' report 定位到第二段第一句 Underwriters Laboratories issued a report last week that found 48% of consumers “feel high-tech manufacturers bring new products to market faster than people need them.”
细节推断题。第二段提到美国保险商实验室公司发布的一项报告指出，48％的消费者“认为高科技制造商向市场投放新产品的速度快于人们的需求度” 。 C“他们认为产品的更新速度比人们所需要的快”是原文的同义转述，故为答案。
What does the author mean by "me-too products"?
【定位】由题干中的“me-too products”，定位到第三段第四句 That is, the new offerings companies are pushing out the door every six months or so are me- too products or ones with just a couple of new features.
推理判断题。文章第三段第四句指出各公司每隔半年左右推出的新产品是 me-too products or ones with just a couple of new features， 句中使用连词 or， 由此我们可推测 me-too products 和 ones with just a couple of new features 意思相似，而后者比较好理解，意为“仅有几个新特征的产品” ， 也可以理解为“没有很大区别的产品” ，故答案为A。
What do American businesses give priority to when marketing their products?
【定位】由题干中的 American businesses, give priority to 和 marketing定位到第三段最后一句 Manufacturers in America valued “speed to market”more than in other countries, the report found.
语义理解题。文章第三段最后一句提到，美国制造商比其他国家的制造商更加注重“产品上市速度”。这里的“更加注重”即“优先考虑”的意思，也就是说，美国制造商优先考虑的是向市场投放产品的速度，故答案为B。
What is the consumers' chief concern about high-tech products?
【定位】 由题干中的 chief concern, high-tech products 定位到第五段第三句 But their top safety concerns are emissions and wireless radio waves.
细节推断题。文章第五段提到了消费者关心的一些问题，明确指出他们最关心的安全问题是辐射和无线电波。故答案为 D。
Why does the author suggest supply-chain labeling?
由题干中的 supply-chain labeling 定位到最后一段第一句 But maybe some sort of supply-chain labeling showing where parts come from in a product?
推理判断题。文章第六段最后一句提到消费者更关心高科技组件的来源地而不是产品的组装地，第七段提到单个产品的各个组件来自不同的供货商，最后一段提出要用供应链标签标注组件的来源地，故答案为 C。
