Nuclear radiation(核辐射)has a certain mystery, 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 but we can’t detect them or 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. 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 serious. This is the case when only a few cells are hit, and when 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. A child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents.

阅读下面的短文,然后按照要求写一篇150词左右的英语短文。
I think that a hero doesn’t have to be someone who saves people or anything, but he or she can be a teacher or a friend. My personal hero is my music teacher, since he puts so much extra effort into teaching us. He does an extra Steel Drum Band for us. He doesn’t have to do anything extra for us, but he chooses to since he loves to teach and be with us so much. Not many other teachers would want to do so much extra stuff for us since they probably get tired of us after a while, but he does since he cares. No matter how annoying we are to him, he always helps us. If we don’t understand what he’s teaching, he helps us more and tries even harder to make us understand everything we need to. He teaches us the proper techniques for holding instruments as well as playing, instead of just yelling at us if we mess up. He will always have a kind thing to say, even if you’re badly failing his class. He won’t be mad. He will just try harder to help. He always remembers his students, and has some sort of special connection of some sort with everyone. He will always remember to smile and talk to you in the halls, even if he only waves, he still notices everyone.

Our thoughts, words, and actions often cause harm to others and to us. Without reconciliation (和解), we cannot deepen our understanding and only cause more suffering.
