第一节 阅读表达 (共5小题;每小题3分，满分15分)

阅读下面的短文,并根据短文后的要求答题(请注意问题后的词数要求)。

[1] Could your cellphone give you cancer? Whether it could or not, some people are worrying about the possibility that cellphones, power lines and WiFi could be responsible for a range of illnesses.

[2] Camilla Rees, an investment banker in the US, moved out of her apartment. She said that when her neighbors moved in and installed a WiFi router (路由器) she lost her ability to think clearly. Since then, she’s been on a movement against low-level electromagnetic fields (电磁场), or EMFs. And she’s not alone. Millions of people say they suffer from headaches and depression when they’re too close to cellphones or other sources of EMFs. If these fears are justified (有正当理由的), then perhaps we should all be worried about the amount of time we spend talking on our phones or plugging into WiFi hotpots.

[3] Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences, 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 (肿瘤). But others believe _________________. Dr Martha Linet at the US National Cancer Institute has reached a different conclusion. “We don’t have the evidence that there’s much danger,” said Linet.

[4] Studies so far suggest a weak connection between EMFs and illness — so weak that it might not exist at all. A multinational investigation (调查) of cellphones and brain cancer has been underway for several years. 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.

[5] According to Robert Park, a professor of physics, the magnetic waves(电磁波)aren’t nearly powerful enough to break apart DNA, which is how known threats, such as UV rays and X-rays, cause cancer.
