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 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 outright by killing masses of cell in vital organs. But even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be significant. This is the case when only a few cells are hit, and if they are killed outright. 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 reproduce themselves in a deformed way. They can grow into cancer. Sometimes this does not show up for many years.
There 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 and feel fine, then die of cancer five, ten, or twenty years later as a result. Or a child can be born weak or liable to serious illness as a result of radiation absorbed by its grandparents.
Radiation can hurt us. We must know the truth.
Which of the following can be best inferred from the passage?
选项
A、The importance of protection from radiation cannot be over-emphasized.
B、The mystery about radiation remains unsolved.
C、Cancer is mainly caused by radiation.
D、Radiation can hurt those who are not aware of its danger.
答案
A
解析
本题是一道引申推断类问题。问从文章中我们可以推断出哪个选项的内容。针对四个选项,利用查阅式阅读法通读全文内容,我们可以看出,在分析了核辐射造成的危害后,作者在最后一段强调,辐射对人有害,我们应该了解它是如何伤害人的。了解这一点的目的当然是为了尽力避免受到辐射,以增强人的自我保护意识。因此,本题的正确答案应是A“预防核辐射的重要性必须要再三强调”。
