2017年职称英语理工类C级专项练习及答案（补全短文）
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.
A report widely circulated among the public says that up to now scientists do not really know enough to guarantee there are no ill-effets 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 Austrnlia, 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 /5mEubail/ adj.移动的 circulate /5sE:kjuleit/ v.流传 electromagnetic /IlektrEJ5mA^nItIk/ adj.电磁的 density /5densiti/ n.密度 transmitter tower发射塔 disregard /7disri5^B:d/ v.不顾 shield /Fi:ld/ n.隔离屏 accelerate /Ak5selEreit/ v.加速，加快注释：
1. 动词 prove用的是过去式形式 proved，这是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呆了一个晚上。
3.介词 by表示“以……(速的度增加)”。
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。 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 areas。此外， many指的是 many transmitter towers。
6. at 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 这一段的第一句说的是，许多微波发射搭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米半径的范围内建造发射塔。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。
