第一篇
Nuclear Power and Its Danger
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 outright by killing masses of cells in vital organs.But even the lowest level of radiation 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.
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 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 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?
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：B解析：第一段就明确指出核能的危险在于核辐射。
第三段提到，即使很微量的辐射也会带来严重的后果，主要因为受损伤的细胞会以崎形的方式自我复制，进而转变为癌症。
not be significant指不太要紧的、不致命的，所以选A。
核辐射会给我们选项A、B和C几个方面的损害，只有D概括较全面，所以D正确。
文章第二段和第四段分别提到了不同的“reasons for some of the mystery tbout nuclear radiation"，由此可以推断，核辐射仍然是一个未解之谜。 -

B:The mystery about radiation remains unsolved.

D:Radiation can hurt those who are not aware of its danger.答案：A解析：由文章第一段“Nuclear power ' s danger to health , safety , and even life itself can be summed up in one word : radiation.”可知，核能对人类健康、安全甚至生命造成的威胁可归纳为一个词：核辐射。故选C。
由文章第三段内容可知，即使是在辐射强度最低的情况下，一些细胞被破坏，也会造成严重的影响，因为这些细胞可能会再生，发展为畸形，并最终生成癌细胞，对人体造成危害。故选B。
由文章第三段第四句话“If the radiation does not hit anything important , the damage may not be significant.”可知，如果辐射没有破坏重要的细胞，这种伤害可能不是致命的。signific ant在此处的意思是“致命的”，与fatal（致命的）意思相近。故选A。
由文章第三段第一句话可知，选项（A杀死主要器官里的大量细胞，导致人立刻死亡）是正确的。由文章第三段最后两句话可知，选项B（损伤细胞，致使细胞多年以后发生癌变）是正确的。由文章最后一段最后一句话可知，选项C（影响我们后代的健康成长）是正确的。故选D。
文章主要讲述了核辐射的危害以及可能导致的严重后果。看四个选项，我们可以推断出选项A（预防核辐射的重要性再强调也不过分）是正确的。故选A。 -

第二篇
Nuclear Power and Its Danger
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 outright by killing masses of cells in
vital organs.But even the lowest level of radiation can do serious damage.There is no level of radiation that is
comnpletely 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 the mystery of nuclear radiation.Serious damage can be done without the
victim being aware at the time that damage occurs. 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?
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：由第一段内容可知核能的危险在于其辐射性。
由第三段的第二句和该段最后四句可知，即使很少的细胞遭核辐射损坏（未被完全杀 死），也会造成严重的后果。
该词是对本句中if条件句所述情况所造成的损害的评述，而其后两句是对该句的补充 说明，由这两句所述的“……你的身体会用健康的细胞取代坏死的细胞”可知，情况并不严重， 故选A。 fatal意为“致命的，灾难性的”,significant意为“重大的，影响深远的”。
由第三段第一句、第三段最后四句和第四段最后一句可知，D项为正确答案。
文章叙述了核辐射危害的严重性、潜伏性和长期性，由此可知，再怎么强调防辐射都不 为过。 第三篇 本文主要介绍了一种预侧山体滑坡的设备。
