As a young man, Tom was a famous artist with a wife and two fine sons. One night, his older son was ill. Tom and his wife thought it was nothing serious. But the boy died suddenly that night..

    After his son died, Tom always felt very sad. To make matters worse, his wife also left him later, leaving him alone with his six-year-old younger son, Emie. Sadly, he turned to alcohol(酒) for help.

As time went by, Tom began to lose everything he had——his land, house, etc. A few months later, Tom passed away alone in a small bar. Hearing of Tom's death, I thought,"What a complete failure!"

   But later, I began to change my earlier opinion. I knew Tom's now adult son, Emie. He is one of the kindest, most caring men. I saw the love between Emie and his children. And I thought that kindness and caring had to come from somewhere.

One day, I asked him what made him become such a specia1 person. Emie said quietly, "My father came into my room every night, give me a kiss and said,"love you, son."

     Hearing his words, I understood everything. Tom didn't leave many things behind. But he had been a kind loving father, and left behind his best love.

    What was discovered by accident? The answer is penicillin (青霉素). It kills germs. By killing germs, it saves lives. Suppose you are sick. You go to a doctor. She examines you. She says you have a “staph” infection (葡萄球菌感染). She gives you some medicine. You take it. The medicine knocks out the staph. Soon you are well. Before penicillin, this would not happen. Staph was almost sure death.

    Everyone wanted a medicine. Laboratories worked day and night. They grew the staph in small dishes. Then they tried to kill it. Nothing worked.

    The laboratory dishes had covers on them. They kept things from falling into dishes. Molds (霉菌) were a big worry. They are always in the air. You can't see them. They're too small. There are thousands of different molds. Molds can make an experiment (实验) fail. That's why dishes are covered.

    Dr. Alexander Fleming was working to kill the staph germ. He worked for years. One day he took a cover off a dish. He looked inside. There was a thick growth of staph germ. There was also some mold. Then he saw something strange. Where the mold was, there was no growth of staph. This is what Fleming probably thought. “By accident, I found a mold to kill the dreaded staph.”

    This is how penicillin was found. But here's the real miracle (奇迹). There are thousands of kinds of molds. But only one kind can kill staph. The mold must have fallen into the dish a few days before. The cover was probably off only a few seconds (秒). In those few seconds the right mold fell into the right dish. Another man might have thrown the dish away. But Fleming was very careful and smart. He understood what the mold did. How lucky the humans were!

    David walked down the street. All he wanted to do was to play basketball with Jim. But his mother told him to return his sister's books to the library on his way to Jim's house.

    In his eyes, books and summertime just don't go together. He thought he had read a lot during the school year. And he had never set foot inside a public library. Today he'd just drop the books off in the outside return box, but it was locked. He had to go inside to return them.

David walked inside the building a few minutes before closing time. He put the books into the return box. After a quick drink of water and a short stop in the toilet, he'd be on his way to meet Jim. He walked out of the toilet. The library lights were turned off. He was locked — in a library.

    David tried to use the telephone, but he couldn't find one. As the sun began to set, he searched for a light and found a little one on the desk. He used a pencil to write a note on a big piece of paper. It read," I'm locked inside. Please call for help." He put it on the front door. Surely, someone passing by would see it. He then turned his attention to the library itself.

    He was surprised to discover that this place was not so bad. Rows and rows of books! When he saw a book about Michael Jordan on the desk, he picked it up. He opened the book and began to read. He felt that being locked in the library didn't seem to be such a terrible thing.

    Watching some children trying to catch butterflies one August afternoon, I thought of my unforgettable experience in my own childhood. When I was a boy of twelve in South Carolina, something happened to me that made me never put any wild creature in a cage.

We lived near a forest, and every evening at dusk the mockingbirds would come and rest in the trees and sing. Their singing is the most beautiful sound I've ever heard.

    I decided that I would catch a young bird and keep it in a cage and in that way, I would have my own private musician.

    I finally succeeded in catching a young bird and put it in a cage. At first, being frightened, the bird fluttered(扑腾) in the cage, but finally it settled down in its new home. I felt very pleased with myself and looked forward to some beautiful singing rom my little musician.

    On the second day, my new pet's mother flew to the cage with food in her mouth. The baby bird ate everything she brought to it. I was pleased to see this. Certainly the mother knew better than I how to feed her baby.

    The following morning when I went to see the bird again, I found it on the floor of the cage, dead. I was terribly surprised! What had happened! I had taken good care of my little bird.

    Arthur Wayne, the famous ornithologist, who happened to be visiting my father at the time, hearing me crying over the death of my bird, explained what had happened. "Mother mockingbird, finding her young in a cage, will sometimes bring it poisonous berries(毒莓). She thinks it better for her young to die than to live in a cage."

    Since then I have never caught any living creature and put it in a cage. All living creatures have a right to live free.
