Of all the lessons taught by the financial crisis,
the most personal has been that Americans aren’t so good at money-management. We
take out home loans we can’t afford. We run up sky-high credit-card debt. We
don’t save nearly enough for retirement. In response, supporters of financial-literacy education are moving with renewed enthusiasm. School districts in states such as New Jersey and Illinois are adding money-management courses to their curriculums. The Treasury and Education departments are sending lesson plans to high schools and encouraging students to compete in the National Financial Capability Challenge that begins in March. Students with top scores on that exam will receive certificates--but chances for long-term benefits are slim. As it turns out, there is little evidence that tr A.

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. lt 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 outnght.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 a result of radiation absorbed by its grandparents. Radiation can hurt us.We must know the truth. The underlined word"significant"in Paragraph 3 most probably means______. A.fatal B.meaningful C.remarkable D.harmful [单选题]电焊作业时产生的有害气体的主要成分是( )。
