      "It hurts me more than you," and "This is for your own good." These are the statements my mother used to make years ago when I had to learn Latin, clean my room, stay home and do homework

     That was before we entered the permissive period in education in which we decided it was all right not to push our children to achieve their best in school. The schools and the educators made it easy to us. They thought that it was all right to be parents who take a let-alone policy. We stopped making our children do homework. We gave them calculators, turned on the television, left the teaching to the teachers and went on vacation.

       Now teachers, faced with children who have been developing at their own pace for the past 15 years, are realizing we've made a terrible mistake. One such teacher is Sharon Klompus who says of her students - "so passive" - and wonders what happened. Nothing was demanded of them, she believes. "Television," says Klompus, "contributes to children's passivity. We're not training kids to work any more. We're talking about a generation of kids who've never been hurt or hungry. They have learned somebody will always do it for them. Instead of saying 'go look it up', you tell them the answer. It takes greater energy to say no to a kid."

     Yes, it does. It takes energy and it takes work. It's time for parents to end their vacation and come back to work. It's time to take the car away, to turn the TV off, to tell them it hurts you more than them but it's for their own good. It's time to start telling them "no" again.

     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.

63. 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.

64. Why does nuclear radiation have a certain mystery?

    A. Because human beings learn its harmfulness.

    B. Because nuclear radiation can kill a person very easily.

    C. Because it can do harm to a person while he doesn't know.
