题文
Nuclear power’s danger to health, safety, and even life itself can be summed up in one word: radiation.Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can’t be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can’t detect them, sense them, without a radio receiver. Similarly, we can’t sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels, radiation can kill an animal or human being immediately by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no levels of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and if they are killed immediately. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can be irradiated（辐射）and feel fine, then die for cancer five, ten, or twenty years later as a result. Or a child can be born weak as a result of radiation absorbed by its grandparents.
Radiation can hurt us. We must know the truth.
小题1:Which of the following statements is true? A．Nuclear radiation is just like common radio waves.B．Nuclear radiation can cause cancer to human beings. C．Nuclear radiation can be detected by human senses.D．Nuclear radiation can be safe to human beings if its level is low.小题2:How can nuclear radiation kill an animal?A．By damaging its heart.B．By killing a few cells.C．By hitting any place in its body.D．By killing many cells in important organs.小题3: If a human being is hit by nuclear radiation, he may _______. A．die of cancer after many yearsB．die immediately C．have a child who may be born weak D．all of the above 题型：未知难度：其他题型
答案
小题1:B
小题2:D
小题3:D
解析
文章介绍核辐射对人类和动物的危害，如果辐射较弱，可能会危害健康，有的影响不是明显的，但是人们可能多年后会死于癌症，或会对后代产生影响，如果核辐射量大，对导致死亡。
小题1:细节题：从第三段的句子：But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They can grow into cancer. Sometimes this does not show up for many years.可知核辐射会导致人类的癌症，选B。
小题2:细节题：从第三段的句子：At very high levels, radiation can kill an animal or human being immediately by killing masses of cells in vital organs. 可知核辐射可以杀死重要器官的细胞从而使动物立刻死亡，选D
小题3:细节题：从第一段可知核辐射可以致人死亡，最后一段可知核辐射可以让人多年后死于癌症，也会生出虚弱的孩子，所以选D
考点
据考高分专家说，试题“Nuclear power’s dang.....”主要考查你对 [健康环保类阅读 ]考点的理解。健康环保类阅读
健康环保累阅读概念：
健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。体裁有记叙文、 说明文、议论文和各种应用文。
健康环保类文章阅读技巧：
健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。阅读此类短文要以现象或事物为中心进行思考，理解现象产生的原因、条件和客观规律等。同时要抓住事物的特征、用途和相互关系等。科普环保类文章一般为说明文，从结构上看大致可分为三个部分：
第一部分一般是文章的首段，主要用来提出文章的主题，即文章想要阐述、说明的主要内容；
第二部分是文章的主体，可由若干个段落组成，对文章的主题进行展开说明；
第三部分是结尾段，对文章的主题进行归纳总结。这类文章多用一般现在时，而且一般多使用客观性词语表述。有时为了强调客观性，也常使用被动语态。
从近几年的考试题来看，科普环保类的文章越来越与人们的实际生活相接近。由于此类文章缺乏故事情节，很多同学对此类文章感到费解。但一般的科普类文章都是就事论事，需要逻辑推理和想象的时候较少，因此此类阅读题也没有同学们想象中的那么难，只要多加训练，就能较好地答题。
