1.Could your cellphone give you cancer?Whether it could or not,some people are worrying about the possibility that phones,powerlines and wi-fi (路由器) could be responsible for a range of illnesses,from rashes to brain tumours.For example,Camilla Rees,48,a former investment banker in the US,moved out of her apartment in San Francisco because of the radiation coming from next door.Rees told the Los Angeles Times that when her neighbors moved in and installed a wi-fi router she lost her ability to think clearly."I would wake up dizzy in the morning.I'd fall to the floor.I had to leave to escape that nightmare,"she said.Since then,she's been on a campaign against low-level electromagnetic fields,or EMFs(低频电磁场).
And she's not alone.Millions of people say they suffer from headaches,depression,nausea and rashes when they're too close to cellphones or other sources of EMFs.
Although the World Health Organization has officially declared that EMFs seem to pose little threat,governments are still concerned.In fact,last April,the European Parliament called for countries to take steps to reduce exposure to EMFs.The city of San Francisco and the state of Maine are currently considering requiring cancer-warning labels on cellphones.
If these fears are reasonable,then perhaps we should all be worried about the amount of time we spend talking on our phones or plugging into wi-fi hotpots.
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% chance that power lines can cause childhood leukemia.Also there's a greater than 90% chance that cellphones can cause brain tumours.
But others believe these concerns are unreasonable paranoia (猜疑).Dr Martha Linet,the head of radiation epidemiology 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 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.
According to Robert Park,a professor of physics at the University of Maryland in the US,the magnetic waves aren't nearly powerful enough to break apart DNA,which is how known threats,such as UV rays and X-rays,cause cancer.
Perhaps it's just psychological.Some experts find that the electro-sensitivity syndrome seems to be similar to chemical sensitivity syndrome,which is a condition that's considered to be psychological.
Whether EMFs are harmful or not,a break in the countryside,without the cellphone,would probably be good for all of us.

分析 本文讨论了使用手机是否会致癌的问题.一个观点是使用手机会致癌,因为有人表现出了明显症状.而另一观点是使用手机很安全.在未明白真实情况时,作者建议我们少使用手机.
解答 71.dangerous/harmful,由文章首句来看Could your cellphone give you cancer?Whether it could or no,本文讨论了使用手机是否会致癌的问题.一个观点是safe to use,则可推断另一观点是dangerous to us,故填dangerous.
72.possible 由第一段some people are worrying about the possibility that phones,有些人担心手机致癌的可能性,空格前有主语,故此处填形容词形式,possible
73.same 由第三段段意可知,数以百万计的人说他们会头痛、抑郁、恶心、皮疹时太靠近手机或其他来源的电磁辐射,像她一样.故此处填same.
74.connection 由倒数第四段 Studies so far suggest a weak connection between EMFs and illness-so weak,迄今的研究表明EMFs和疾病之间的弱联系很弱.故填connection.
75.destroy 由倒数第三段the magnetic waves aren't nearly powerful enough to break apart DNA,电磁波几乎没有足够强大的能力来瓦解DNA.此处填 break apart 的同义词,destroy毁坏,摧毁.
76.reasons 由倒数第二段which is a condition that's considered to be psychological,这是一种心理上的疾病.可知这是心理原因,且用复数,故填 reasons.
77.suggestions 由题右的两项措施可知这是在叙述作者对手机是否致癌问题的态度和建议.且此处应使用复数,故填suggestions.
78.concerned 由第四段governments are still concerned.可知政府依旧担心这个问题.故填concerned.
79.reduce 由最后一段a break in the countryside,without the cellphone,would probably be good for all of us,在乡下休息,没有手机,可能会对我们都好.可知作者建议我们减少使用手机的机会.故填reduce.
80.rural 由最后一段a break in the countryside,without the cellphone,would probably be good for all of us,在乡下休息,没有手机,可能会对我们都好.故此处填乡下地区,用形容词形式 rural,乡村的.
