2017年職稱英語理工類C級專項練習及答案（補全短文）
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.
詞匯: mobile /5mEubail/ adj.移動的 circulate /5sE:kjuleit/ v.流傳 electromagnetic /IlektrEJ5mA^nItIk/ adj.電磁的 density /5densiti/ n.密度 transmitter tower發(fā)射塔 disregard /7disri5^B:d/ v.不顧 shield /Fi:ld/ n.隔離屏 accelerate /Ak5selEreit/ v.加速，加快注釋：
1. 動詞 prove用的是過去式形式 proved，這是虛擬語氣表示假設的用法。
2. Nobody’s going to drop dead overnight …“沒有人會在一個晚上倒地死去……” overnight是副詞，意為“一夜間;一下子;整夜”。如： This stadium was not built overnight.這個體育場不是一下子建起來的。 On his way to Europe, John stayed with his parents in Chicago overnight.在去歐洲的途中，約翰在芝加哥他父母那兒呆了一個晚上。
3.介詞 by表示“以……(速的度增加)”。
4.介詞 by表示“到……前”。如： By Thursday morning you should complete writing the experiment report. 到周四上午你應該寫完實驗報告。 5. many in high density residential areas 是獨立主格結(jié)構。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……”短語中的 that指代 rate。倍數(shù)的表達法是：“數(shù)字 +times+名詞/that”。如： His salary is three times that of mine. 他的薪水比我多兩倍。 The sales volume of refrigerators in 2000 was twice that in 1999. 2000年冰箱的銷量比 1999年多一倍。練習：
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.
答案與題解：
1. C “空 1”應該填入與 low-level radiation有關的'內(nèi)容，例如： low-level radiation究竟有害還是無害。所以， C是合適的選項。此外，直接引語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的現(xiàn)狀。選項 B的內(nèi)容是對到 2000年之前手機發(fā)展前景的預測，內(nèi)容連貫，是正確答案。
3. E 這一段的第一句說的是，許多微波發(fā)射搭建在人口稠密的居民區(qū)。選項 E的內(nèi)容涉及微波發(fā)射塔的地點選擇只考慮到地理位置，而不顧及社區(qū)的安全。選項 E擴展了第一句表達的信息。此外選項 E 中出現(xiàn) tower這個詞，與第一句的 tower相呼應，也佐證了選擇的合理性。
4. A “空 4”前面一句說的是 Robert Bell建議政府應該禁止在兒童比例高的地區(qū)(如學校操場、兒童醫(yī)療中心、居住小區(qū)等 )的 500米半徑的范圍內(nèi)建造發(fā)射塔。選項 A說明為什么要這樣做的原因，因而是答案。
5. D “空 5”后面一句說的是 major telephone companies出錢資助研究項目的問題，提示了 D是正確答案。
