Question

Cellphones: is there a cancer link?
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 95 percent chance that power lines can cause childhood leukemia(白血病). Also there’s a greater than 90 percent 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(xué)) 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 13 countries 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.

文章講述的是關(guān)于手機(jī)等輻射是否對人體有害的各方觀點(diǎn)。
1.推理判斷題。根據(jù)第二段可知，有些專家明確認(rèn)識輻射會(huì)致病，并警告人們，
2.推理判斷題。根據(jù)第三段最后一句可知，該專家認(rèn)為沒有任何證據(jù)可以證明輻射可以對人體造成傷害。
3.猜測詞義提。 根據(jù)文章可知此處意為在進(jìn)行中。
4.文中作者并沒有明確表明自己贊成還是反對的觀點(diǎn)，所以是比較客觀的看待該問 題。
