A Radiation Reality Check(关于辐射的真相)
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, isnt 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. Were not dropping dead all together from radiation poisoning or its ensuing cancers on a daily basis because, like all poisons, it isnt the particular atom that will get you. Its the dose. And damage from radioactivity requires a much greater dose than any of us would have believed.
【问题】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
【词汇突破】
1. All together = en masse全体地
2. on a daily basis = everyday每天
3. ensuing 随后的
4. havoc= mayhem 灾难
5. obese 庞大
6. vicious 这里理解为:恶性的
【全文翻译】放射性产生的根源是一个太庞大的原子违背了万有引力定律(我们物质世界存在的基本原理)并发生分裂,释放出两种粒子和一束类似于X光的射线。过量暴露在射线中就好像恶性晒伤一样,会造成皮肤损伤并提高罹患癌症的风险,但由于粒子的体积太大,所以它们无法穿透我们的皮肤,也就是说这些粒子要被人类吞入或吸入才会造成损伤。核事故中真正可怕的不是放射性尘埃而是堆芯熔毁,堆芯熔毁能够烧穿地表并渗入地下水。堆芯熔毁可以带来农业灾害和不宜吸入的放射性尘埃。人类不会因为放射性毒害或由此引发的癌症而每天大量死亡,这是因为与所有的有毒物质一样,罪魁祸首不是特定的原子,而是剂量。放射性造成损伤所需的剂量远远超过我们通常认为的水平。
通过今天KK教授带来的相关辐射真相的阅读语料,各位考生是不是能找到其中的学习精髓呢,学习同源期刊文章中的表达方式,掌握最新热点语料,做考研英语的先行军。最后的决战转眼就到,希望大家站好最后一班岗。预祝各位考生金榜题名!
