14.As is known to everyone,radiation is a word that can be used to describe nuclear power's danger to health,safety,and even life itself.Nuclear radiation has a certain mystery about it,partly because it cannot be detected (探测) 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 important 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 an unusual 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 knowledge of the person at the time that damage has occurred.A person can be irradiated(放射治疗) and feel fine,then die of cancer five,ten,or twenty years later as a result.Or a child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents.
Radiation can hurt us.We must know the truth.

D.nuclear mystery
73.Radiation can lead to serious results even at the lowest levelD.
A.when it kills few cells
B.unless the damaged cells can reproduce themselves
C.though the damaged cells can repair themselves
D.if it damages few cells
74.Radiation can hurt us in the way that it canD.
A.kill large numbers of cells in main organs so as to cause death immediately
B.damage cells which may grow into cancer years later
C.affect the healthy growth of our younger generation
D.lead to all of the above results
75.Which of the following can be best inferred from the passage?B
A.The mystery about radiation remains unsolved.
B.The importance of protection from radiation cannot be overemphasized (过分强调).
C.Cancer is mainly caused by radiation.
D.Radiation can hurt those who do not know about its danger.

解答 ADDB
72 A 细节题.由第一段"As is known to everyone,radiation is a word that can be used to describe nuclear power's danger to health,safety,and even life itself."可知核能的危险之处在于它的核辐射,故正确答案为A.
73 D 细节题.由第三段第二句"But even the lowest levels can do serious damage."和第六句"But if the few cells are only damaged,and if they reproduce themselves,you may be in trouble."可知,如果稀有细胞被辐射损坏则会造成严重后果,所以D项正确.此题干扰项为A项,A项偷换概念,文中只说损坏细胞,而不是杀死细胞,所以A项错误.故正确答案为D
74 D 细节题.由第三段第一句"At very high levels,radiation can kill an animal or human being outright by killing masses of cells in important organs."可知A项正确;由第三段倒数第二句"They can grow into cancer."可知B项正确;由第四段最后一句"Or a child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents."可知C项正确.故正确答案为D.
75 B 推断题.由文章最后一段"Radiation can hurt us.We must know the truth."可知作者强调了核辐射对人类的伤害,因此保护人类免受核辐射伤害十分重要,B项符合文意,故正确答案为B.
点评 考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.

Scientists have known for a long time that the sun has an 11-year cycle during which radiation from the sun reaches a(n) (42)A then falls.But detecting a clear link of the cycle to the weather has proved much (43)H.
"Our research notices a link between solar activities and regional winter climate,"lead author Sarah Ineson of the UK Met Office told the reporters in an email.
Her team focused on the data from the recent minimum solar radiation period during 2008-10,which was a(n) (44)G calm period for the sun but at the same time,(45)C winters in the U.S and Europe were recorded which brought troubles to many businesses and made people's lives difficult.
The researchers found that a reduction in radiation from the sun can affect wind patterns,(46)D cold winters.
"While radiation levels won't tell us what the day-to-day weather will be,they provide the exciting (47)B of improved prediction for winter conditions for months and even years ahead.These predictions play an important role in long-term weather planning,"Ineson said.
Ineson's team used the data in a complex computer to (48)K long-term weather patterns.It successfully reproduced what scientists had observed happening in the upper atmosphere during changes in solar radiation.More study was needed,though.The key (49)F in the experiment lay in the satellite data used,because it spans(跨度) only a few years."So there are still questions concerning whether the current research results are accurate and whether they can be (50)I to other solar cycles,"she said.
