Mobile Phones
Mobile phones should carry a label if they proved1 to be a dangerous source of radiation,according to Robert Bell,a scientist.And no more mobile phone transmitter towers should be built until the long-term health effects of the electromagnetic radiation they emit are scientifically evaluated,he said."Nobody’s going to drop dead overnight2 but we should be asking for more scientific information，"Robert Bell said at a conference on the health effects of low-level radiation.____1____
A report widely circulated among the public says that up to now scientists do not really know enough to guarantee there are no ill-effects on humans from electromagnetic radiation.According to Robert Bell,there are 3.3 million mobile phones in Australia alone and they are increasing by 2,000 a day3.____2____
As well,there are 2,000 transmitter towers around Australia,many in high density residential areas5.____3____The electromagnetic radiation emitted from these towers may have already produced some harmful effects on the health of the residents nearby.
Robert Bell suggests that until more research is completed the Government should ban construction of phone towers from within a 500 metre radius of school grounds,child care centres,hospitals,sports playing fields and residential areas with a high percentage of children.____4____ He adds that there is also evidence that if cancer sufferers are subjected to electromagnetic waves the growth rate of the disease accelerates.
____5____ According to Robert Bell,it is reasonable for the major telephone companies to fund it.Besides,he also urges the Government to set up a wide-ranging inquiry into possible health effects.
词汇：
mobile 移动的 electromagnetic 电磁的
transmitter tower发射塔 shield 隔离屏
circulate 流传 density 密度
disregard 不顾 accelerate 加速，加快
注释：
1.动词prove用的是过去式形式proved,这是一种虚拟语气表示假设的用法。
2.Nobody’s going to drop dead overnight ...没有人会在一个晚上倒地死去……”overnight是副词，意为"一夜间;一下子;整夜”。如：This stadium was not built overnight.这个体育场不是一下子建起来的。
On his way to Europe,John stayed with his parents in Chicago overnight.在去欧洲的途中，约翰在芝加哥他父母那儿待了一个晚上。
3.介词by表示"以……(的速度增加)”。
4.介词by表示"到……前”。如：
By Thursday morning you should complete writing the experiment report.到周四上午你应该写完实验报告。
the year 2000：公元2000年
5.many in high density residential areas是独立主格结构。注意它省略了being，即many(being)in high density residential areas0此夕卜，many指的是many transmitter towers。
6.vat a rate more than three times that of adults可以理解为at a rate(that is)more than three times that of adults，意为"以比成人多两倍的比率”短语中的that指代rate。倍数的表达法是："数字+times+名词/that”。如：
His salary is three times that of mine.他的薪水比我多两倍。
The sales Volume of refrigerators in 2000 was twice that in 1999.2000年冰箱的销量比1999年多一倍。
练习：
A He says there is emerging evidence that children absorb low-level radiation at a rate more than three times that of adults6.
B By the year 20004 it is estimated that Australia will have 8 million mobile phones ：nearly one for every two people.
C "If mobile phones are found to be dangerous,they should carry a warning label until proper shields can be devised,"he said.
D Then who finances the research?
E For example,Telstra,Optus and Vodaphone build their towers where it is geographically suitable to them and disregard the need of the community.
F The conclusion is that mobile phones brings more harm than benefit.
答案与题解：
1.C"空1”应该填入与low-level radiation有关的内容，例如：low-level radiation究竟有害还是无害。所以，C是合适的选项。此外,直接引语也佐证了选择的合理性。
2.B"空2”前面一句介绍了澳大利亚拥有手机的现状。选项B的内容是对到2000年之前手机发展前景的预测，内容连贯，是正确答案。
3.E这一段第一句说的是，许多微波发射塔建在人口稠密的居民区。选项E的内容涉及微、波发射塔的地点选择只考虑到地理位置，而不顾及社区的安全。选项E扩展了第一句表达的信息。此外，选项E中出现tower这个词，与第一句的tower相呼应，也佐证了选择的合理性。
4.A"空4”前面一句说的是Robert Bell建议政府应该禁止在儿童比例高的地区(如学校操场、儿童医疗中心、居住小区等)的500米半径范围内建造发射塔。选项A说明为什么要这样做的原因，因而是答案。
5.D"空5”后面一句说的是major telephone companies出钱资助研究项目的问题，提示了D是正确答案。
译文：移动电话
根据科学家罗伯特·贝尔的观点，如果移动电话被证实是一种辐射危害的来源的话，那在上 面应该贴一个标签。而且直到移动电话发射塔的电磁辐射对人体健康的长期影响有一个合乎科学 的评价之前，不能建造更多的发射塔。"没有人会在一个晚上就倒地死去，伹我们还是应该寻找更 多的科学论据去指出它的危害。”罗伯特?贝尔在一次关于少量辐射对人体健康影响的会议上说。"如果移动电话被证明有危害，就应该在它上面贴一个警告标签，直到设计出合适的隔离屏为 止。”他说。
在公众中一个广泛的流行说法是，现在的科学家们还不能完全地保证，电磁辐射对人类没有 负面影响。正如罗伯特?贝尔所指出，仅在澳大利亚就有330万部移动电话，而且正以每天 2 000部的速度增加。估计到公元2000年之前澳大利亚将拥有800万部移动电话，接近每两人一部手机。
同时，在澳大利亚境内分布着2 000座发射塔，其中有许多还坐落在人口密集的居民区。例 如，Telstra,Optus和Vodaphone所建造的发射塔从地理位置上来说是合适的，但都忽视了公众的 需求。从这些发射塔发出的电磁辖射可能已经对附近的居民产生了一些有害影响。
罗伯特·贝尔建议，在更多的研究工作未完成之前，政府应该禁止在学校操场、儿童日托中 心、医院、运动场所以及儿童占比例较高的居住场所方圆500米范围内建造发射塔。他说显现的 证据表明，儿童以成年人三倍多的比例吸收微量辐射。同时他补充说还有一个证据证明如果癌症 患者受到电磁波的辐射，就会导致疾病的加速恶化。
那么谁资助这项研究呢?罗伯特·贝尔认为由较大的电话公司提供资金是合情合理的，他还极力主张政府进行一系列广泛的关于辐射可能对身体健康有所影响的调查与研究。
