16.Could your cellphone give you cancer?Whether it could or not,some people are worrying about the possibility that phones,power lines and wi-fi could be responsible for a range of illnesses,from rashes to brain tumors.
Some say there is evidence to support the growing anxieties.David Carpenter,a professor of environmental health sciences at the university at Albany,in New York,thinks there's a greater than 95percent chance that power lines can cause childhood leukemia (白血。瓵lso there's a greater than 90percent chance that cellphones can cause brain tumors."It's apparent now that there's a real risk,"said Carpenter.
But others believe these concerns are unjustified.Dr Martha Linet,the head of radiation epidemiology(流行病學) at the US National Cancer Institute,has looked at the same research as Carpenter but has reached a different conclusion."I don't support warning labels for cellphones,"said Linet."We don't have the evidence that there's much danger."
Studies so far suggest a weak connection between EMFs (電磁場) and illness-so weak that it might not exist at all.A multinational investigation of cellphones and brain cancer,in 13countries outside the US,has been underway for several years.It's funded in part by the European Union,in part by a cellphone industry group.The final report should come out later this year,but data so far don't suggest a strong link between cellphone use and cancer risk.

分析 本文講述的是關(guān)于手機等輻射是否對人體有害的各方觀點.
解答 CABA
12.C 推理判斷題.根據(jù)文中第二段."It's apparent now that there's a real risk,"said Carpenter.可知,有些專家明確輻射會致病,并警告人們,故選C項.
13.A 推理判斷題.根據(jù)第三段The final report should come out later this year,but data so far don't suggest a strong link between cellphone use and cancer risk.可知,該專家認為沒有任何證據(jù)可以證明輻射可以對人體造成傷害,故選A項.
14.B 推理判斷題.根據(jù)第三段The final report should come out later this year,but data so far don't suggest a strong link between cellphone use and cancer risk.可知文中作者并沒有明確表明自己贊成還是反對的觀點,所以是比較客觀 地看待該問題,故選B項.
15.A 考查主旨標題.文章講述的是關(guān)于手機等輻射是否對人體有害的各方觀點,故選A項.
點評 學生需要認真閱讀原文,把握文章大意,對文章脈絡有整體的了解,能仔細查找文中細節(jié),并能根據(jù)文章內(nèi)容進行合理的推測判斷.
