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 build until the long-term health effects of the electromagnetic radiation they emit is 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 by3 2, 000 a day.

_____ (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.

1. 動(dòng)詞prove用的是過(guò)去式形式proved,這是一種虛擬語(yǔ)氣表示假設(shè)的用法。

2. Nobody’s going to drop dead overnight … : “沒(méi)有人會(huì)在一個(gè)晚上倒地死去……” overnight 是副詞，意為“一夜間;一下子;整夜”。如：

the year 2000 ： 公元2000年。

5. many in high density residential areas :是獨(dú)立分詞短語(yǔ)。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 可以理解為 at a rate (that is ) more than three times that of adults, 意為“以比成人多兩倍的比率……”短語(yǔ)中的that 指代rate。倍數(shù)的表達(dá)法是：“數(shù)字 + times + 名詞/that”。如：

His salary is three times that of mine.

The sales volume of refrigerators in 2000 was two times that in 1999.

答案與題解：

1. C “空1”應(yīng)該填入與low-level radiation 有關(guān)的內(nèi)容，例如 low-level radiation 究竟有害還是無(wú)害。所以，C是合適的選項(xiàng)。此外，直接陰郁也佐證了選擇的合理性。

2. B “空2”前面一句介紹了澳大利亞擁有手機(jī)的現(xiàn)狀。選項(xiàng)B的內(nèi)容是對(duì)到2000年年底之前手機(jī)發(fā)展前景的預(yù)測(cè)，內(nèi)容連貫，是正確答案。

3. E 這一段的第一句說(shuō)的是，許多微波發(fā)射塔建在人口稠密的居民區(qū)。選項(xiàng)E的內(nèi)容涉及微波發(fā)射塔的地點(diǎn)選擇只考慮到地理位置，而不顧及公眾的需求。選項(xiàng)E擴(kuò)展了第一句表達(dá)的信息。此外，選項(xiàng)E中出現(xiàn) tower 這個(gè)詞，與第一句的 tower 相呼應(yīng)，也佐證了選擇的合理性。

4. A “空4”前面一句說(shuō)的是Robert Bell建議政府應(yīng)該禁止在學(xué)校操場(chǎng)、兒童日托中心、醫(yī)院、運(yùn)動(dòng)場(chǎng)所以及兒童占比例較高的居住場(chǎng)所方圓500米范圍內(nèi)建發(fā)射塔。選項(xiàng)A說(shuō)明要這樣做的原因，因而是答案。

5. D “空5”后面一句說(shuō)的是 major telephone companies 出錢(qián)資助研究項(xiàng)目的問(wèn)題，提示了D是正確答案。
