　　Mobile Phones

Mobile phones should carry a label if they proved to be a dangerous source of radiation, according to Robert Bell, a scientist. And no more mobile phone transmitter towers should be build until the long-term health effects of the electromagnetic (電磁的) radiation they emit is scientifically evaluated,he said. "Nobody's going to drop dead overnight 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 (傳播) 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 day.2

As well, there are 2,000 transmitter towers around Australia, many in high density (密度)residential areas. 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 ( 隔離屏 ) 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 (加速，加快) .

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.

A. He says there is emerging evidence that children absorb low-level radiation at a rate more than three times that of adults.

B. By the year 2000 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 (不顧) the need of the community.

F. The conclusion is that mobile phones bring more harm than benefit.

答案與解析

1.C。本段講的是手機輻射，而其空白處講的是Robert參加了一個有關低輻射對健康的影響的會議，所以緊接着説的還是有關輻射的，所以答案選c。

2.B。空白處前面一句介紹了澳大利亞擁有手機的現狀，後面談論的應該還是澳大利亞的.情況，所以選B，即對到2000年年底之前手機發展前景的預測，內容上保持了連貫。

3.E。這一段的第一句説的是，許多微波發射塔建在人口稠密的居民區。選項E的內容涉及微波發射塔的地點選擇只考慮到地理位置，而不顧及公眾的需求。選項E擴展了第一句表達的信息。此外，選項E中出現了tower這個詞，與第一句的tower相呼應。

4.A。空白處前面一句説的是Robert Bell建議政府應該禁止在學校操場、兒童日託中心、醫院、運動場所以及兒童佔比例較高的場所方圓500米範圍內建發射塔。選項A説明要這樣做的原因，因而是答案。

5.D。空白處後面一句説的是major telephone companies出錢資助研究項目的內容，提示D是正確答案，在內容上保持了連貫。
