考研英語(yǔ)命題老師對(duì)命題文章的選擇十分講究，通常選取自最新的外文期刊雜志，而且隨著考研腳步的臨近，考生更需要新鮮的閱讀語(yǔ)料來(lái)刺激學(xué)習(xí)的感官，小編整理了許多真題同源期刊的文章，有助于考生在備考中接收到最新鮮的閱讀素材。今天小編就帶各位考生來(lái)了解一下輻射的真相。
A Radiation Reality Check(關(guān)于輻射的真相)
The source of radioactivity is an atom so obese that it defies the laws of attraction gluing together our material world and spits out little pieces of itself -- two kinds of particles and a stream of gamma rays, similar to X-rays. An overdose of gamma rays is like a vicious sunburn, with skin damage and elevated cancer risks, but those particles are too big to penetrate our skin, meaning that they need to be swallowed or inhaled to wreak damage. The truly fearful event in a nuclear accident, then, isn't fallout but meltdown, where the core burns through the floor and suffuses the water table. There it causes agricultural havoc and radioactive dust that you better not breathe. We're not dropping dead all together from radiation poisoning or its ensuing cancers on a daily basis because, like all poisons, it isn't the particular atom that will get you. It's the dose. And damage from radioactivity requires a much greater dose than any of us would have believed.
【問題】According to the passage what ultimately causes the death of the human being ?
(A) The vicious gamma rays
(B) The quantity of radioactivity
(C) The radioactive dust
(D) The meltdown in a nuclear accident
【答案】B
【詞匯突破】
1. All together = en masse 全體地
2. on a daily basis = everyday 每天
3. ensuing 隨后的
4. havoc= mayhem 災(zāi)難
5. obese 龐大
6. vicious 這里理解為：惡性的
【全文翻譯】放射性產(chǎn)生的根源是一個(gè)太龐大的原子違背了萬(wàn)有引力定律(我們物質(zhì)世界存在的基本原理)并發(fā)生分裂，釋放出兩種粒子和一束類似于X光的 γ射線。過量暴露在γ射線中就好像惡性曬傷一樣，會(huì)造成皮膚損傷并提高罹患癌癥的風(fēng)險(xiǎn)，但由于粒子的體積太大，所以它們無(wú)法穿透我們的皮膚，也就是說這些粒子要被人類吞入或吸入才會(huì)造成損傷。核事故中真正可怕的不是放射性塵埃而是堆芯熔毀，堆芯熔毀能夠燒穿地表并滲入地下水。堆芯熔毀可以帶來(lái)農(nóng)業(yè)災(zāi)害和不宜吸入的放射性塵埃。人類不會(huì)因?yàn)榉派湫远竞蛴纱艘l(fā)的癌癥而每天大量死亡，這是因?yàn)榕c所有的有毒物質(zhì)一樣，罪魁禍?zhǔn)撞皇翘囟ǖ脑�，而是劑量。放射性造成損傷所需的劑量遠(yuǎn)遠(yuǎn)超過我們通常認(rèn)為的水平。
通過今天KK教授帶來(lái)的相關(guān)輻射真相的閱讀語(yǔ)料，各位考生是不是能找到其中的學(xué)習(xí)精髓呢，學(xué)習(xí)同源期刊文章中的表達(dá)方式，掌握最新熱點(diǎn)語(yǔ)料，做考研英語(yǔ)的先行軍。最后的決戰(zhàn)轉(zhuǎn)眼就到，希望大家站好最后一班崗。預(yù)祝各位考生金榜題名!
