题文

Cell phones:  is there a cancer link?Could your cell phone 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 illness, 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 95 percent chance that power lines can cau childhood leukemia(白血病). Also there’s a greater than 90 percent chance that cell phones can cau brain tumors. “It’s apparent now that there’s a real risk, ” said Carpenter. But others believe the concerns are unjustified. Dr Martha Linet, the head of radiation epidemiology(流行病学) at the US National Cancer Institute, has looked at the same rearch as Carpenter but has reached a different conclusion. “I don’t support warning labels for cell phones, ” said Linet. “We don’t have the evidence that there’s much danger. ”Studies so far suggest a weak connection between EMFs(电磁场) and illness— so weak that it might not exist at all. A multinational investigation of cell phones and brain cancer, in 13 countries outside the US, has been underway for veral years. It’s funded in part by the European Union, in part by a cell phone industry group. The final report should come out later this year, but data so far don’t suggest a strong link between cell phone u and cancer risk. 小题1:From the passage we can learn that some people are worried becau _______. A．they have evidence that the u of cell phones can lead to cancerB．they make a fuss over cell phone uC．some experts have given a warningD．cell phones are responsible for brain tumors小题2:By saying “I don’t support warning labels for cell phones, ” Dr Martha Linet has the idea that _______.

解析

文章讲述的是关于手机等辐射是否对人体有害的各方观点。小题1:推理判断题。根据文中第二段的内容可知，有些专家明确辐射会致病，并警告人们。选C小题2:推理判断题。根据第四段最后一句but data so far don’t suggest a strong link between cell phone u and cancer risk.可知，该专家认为没有任何证据可以证明辐射可以对人体造成伤害。所以这些担心是没有必要的，选A小题3:推理判断题。文中作者并没有明确表明自己赞成还是反对的观点，所以是比较客观 地看待该问题。选B
