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.

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：

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。
