Question

【题目】“Mobile phones killed our man.” screamed one headline last year. Also came statements that an unpublished study had found that mobile phones cause memory loss. And a British newspaper devoted its front page to a picture supposedly showing how mobile phones heat the brain. For anyone who uses a mobile phone, these are worring times. But speak to the scientists whose work is the focus of these scared and you will hear a different story.

What we do have, however, are some results suggesting that mobile phones’ emission(辐射) have a variety of strange effects on living tissue that can’t be explained by the general radiation biology. And it’s only when the questions raised by these experiments are answered that we’ll be able to say for sure what mobile phones might be doing to the brain.

One of the strange effects comes from the now famous “memory loss” study. Alan Preece and his colleagues at the University of Bristol placed a devic(装置) that copied the microwave emission of mobile phones to the left ear of volunteers. The volunteers were all good at recalling words and pictures they had been shown on a computer screen. Preece says he still can’t comment on the effects of using a mobile phone for years on end. But he rules out the suggesting that mobile phones have an immediate effect on our cognitive(感知的) abilities. “I’m pretty sure there is no short-term memory.” he says.

Another expert, Tatterasll, remarked that his latest findings have removed fears about memory loss. One result, for instance, suggests that nerve cell synapses(神经元突触) exposed to microwaves become more—rather than less—receptive to under-going changes linked to the memory formation.

It would be an even happier outcome if microwave turned out to be good for you. It sounds crazy, but a couple of years ago a team led by Willian Adey at the Veterans Affairs Medical Center in California found that mice exposed to microwave for two hours a day were less likely to develop brain tumours(肿瘤) when given a cancer-causing chemical.

So should we forget about mobile phone radiation causing brain tumours and making us unable to think clearly or reasonably?

“If it doesn’t cause cancer in animals and cells, then it probably isn’t going to cause cancer in humans,” says William. And while there’s still no absolute evidence that mobile phone does damage your memories or give your cancer, the unanimity is: Don’t panic.

【1】What worries people who use mobile phones?

A. Mobile phones will kill them.

B. Mobile phones cause memory loss.

C. Mobile phones heat the brain.

D. All above is right.

【2】What is the attitude of Prece on the suggestion that mobile phones have an immediate effect on our congnitive abilities?

A. Doubt.B. Disagree.C. Approve. D. Wait and see.

【3】The underlined word “unanimity ”in the last paragraph most probably means “_______”.

A. consensusB. disagreementC. possibilityD. impossibility

【4】From the fifth paragraph, we can infer that being exposed to microwaves for two hours _________.

A. can result in killing you

B. is likely develop brain tumours

C. is unlikely to develop brain tumours

D. will cause your loss of memory for ever

Answer 1

【答案】

【1】D

【2】B

【3】A

【4】C

【解析】

试题分析：本文讲的是手机辐射对人的影响。

【1】D 细节理解题。根据文章第一段中“Mobile phones killed our man.”第二段中mobile phones’ emission(辐射) mobile phones might be doing to the brain.第三段中One of the strange effects comes from the now famous “memory loss”可知，A、B、C三项都符合题意，故选D。

【2】B 推理判断题。根据第三段倒数第二句But he rules out the suggesting that mobile phones have an immediate effect on our cognitive(感知的) abilities. “I’m pretty sure there is no short-term memory.可知，他排除了这一建议，认为手机对我们的感知能力的影响是直接的。故Prece的态度是“不同意”。故选B。

【3】A 词义猜测题。虽然仍然没有绝对的证据表明手机确实对你的记忆有伤害，使你得癌症，但一致的意见是：不要惊慌。故“不要惊慌”是一致的建议。故选A。

【4】C 细节理解题。根据第五段中mice exposed to microwave for two hours a day were less likely to develop brain tumours(肿瘤) when given a cancer-causing chemical.可知，一天曝露于微波下两个小时不可能发展成脑瘤。故选C。

【学法指导】

任何一篇文章中的句子在内容上都不是绝对孤立的，都跟句子所在的段落及整整篇文章有关。利用上下文提供的情景和线索，进行合乎逻辑的综合分析进而推测词义，是阅读过程中的一大关键，这也是近年来高考考查的热点。最常见的就是利用上下文语境、常识和语法关系推断词义。

①抓住所需推断词汇前后的“mean”或系动词或破折号等直接定义该词的部分。

②抓住文章主旨与该段所表达的中心。特别对于议论文要牢记论点与论据的相互支撑关系。

③通过例证、比喻、对照、插入语等语法结构推断词义。
