问题     U. S. jeans maker Levi Strauss & Co. denied it was playing on consumer fears by launching a line of trousers fitted with "anti-radiation(防辐射)" pockets for mobile phones. The trousers, with a lining which the makers say shields(防护物)against radiation, are designed by Dockers, a brand name of Levi Strauss. "We are not implying in any way that mobile phones are dangerous. Our intention is not to cash in on consumer fears but provide the consumers with what they want," Levi’s European communications manager Cedric Jungpeter said. The design was the fruit of extensive market research showing that the fashion conscious was also health conscious, Jungpeter said. "The debate is open. Although no study has proved mobile phones are harmful, no study has proved the contrary either. " He added. Worldwide studies into the possible dangers of mobile phones produce often conflicting conclusions. A recent one carried out by Australian researchers over a three-year period showed that radio emissions from mobile phones did not trigger the growth of tumors in mice, and therefore probably did not do so in humans either. And another Australian study concluded cellular phones could foster tumor growth. Swedish research published recently concluded that long-term users of first generation mobile phones faced an up to 80 percent greater risk of developing brain tumors than non-users. But a Danish study last year of 400,000 mobile phone users showed no increased cancer risk.
We may infer from the passage that______.

选项 A、anti-radiation trousers will fuel mobile phone debate
B、long-term users of mobile phones face a greater cancer risk than non-users
C、radiation from mobile phones could foster tumor growth in mice
D、anti-radiation trousers are a fearful sign that mobile phones are dangerous

答案A

解析 这也是一道推理题。文章中说全世界对手机潜在危害的研究经常得出互相矛盾的结论。而且从后面澳大利亚两项研究结果和丹麦的研究表明长期使用手机对肿瘤患病几率的影响尚未确定,所以选项B不准确。选项C也不准确,因为文中明确说澳大利亚的实验表明手机辐射并不会使老鼠患肿瘤。另外,文章中塞德里克·君皮特强调了设计带防辐射裤兜的裤子并非是想说手机是危险品,而只是想要迎合客户的需求。选项D确定说防辐射裤标志着手机就是危险品的说法不准确。文章由防辐射裤引出对手机辐射危害性的讨论,而紧接着“The debate is open.”和“全世界对手机潜在危害的研究经常得出互相矛盾的结论”可以推出防辐射裤将使人们对手机辐射的讨论更加激烈,所以选项A正确。
