2017年职称英语理工类补全短文模拟习题及答案（1）

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.

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。
