A poor farmer had a friend who was famous for the wonderful apple trees he grew.

    One day, his friend gave the farmer a young apple tree and told him to plant it. The farmer was pleased with the gift, but he did not know where to plant it.

    He was afraid that if he planted the tree near the road, strangers would steal the fruit. If he planted the tree in one of his fields, his neighbours would come at night and steal some of the apples. If he planted the tree near his house, his children would take the fruit. Finally he planted the tree in his woods. But without sunlight and good soil(土壤), the tree soon died.

    Later the friend asked the farmer why he had planted the tree in such a poor place. "What's the difference?" the farmer said angrily and then told what he had thought.

    "Yes, "said the friend, "but at least someone could have enjoyed the fruit. Now you not only have robbed everyone of the fruit, but also you have destroyed(毁掉) a good apple tree!"

    A young lady was driving alone through the street. It was dark and rainy. Suddenly she saw an old woman by the side of the road, holding up her hands as if she wanted a lift(搭便车). “I can't leave her out in this weather,” the young lady said to herself. She stopped her car and opened the door.

    “Do you want a lift?” she asked. The old woman nodded and got on the car. After a while, she said to the old woman, “Have you been waiting for a long time?” The old woman shook her head, “Strange” the young lady thought. She tried again, “Bad weather, isn't it?” The old woman nodded.

    Then the young lady noticed the old woman's hands, which were large and hairy. Suddenly she realized the woman was a man! She was frightened at first. Then she stopped the car. “I couldn't see out of the rear screen(后挡风玻璃),”she said, “Would you mind cleaning it for me?”

    “The old woman” nodded and opened the door. As soon as “she”got out of the car, the frightened young lady drove off as fast as she could.

    When she got home, she noticed “the old woman” had left her handbag behind, she picked it up and opened it. Inside there was a gun.

    My name is Bill. I'm from England. I am a worker. I work in a clothes shop. My wife , Ann, is a teacher. She teaches English in a junior high school. We have two kids: a son and a daughter. They are students. Jim is our son. Now he is in his favorite T-shirt and blue pants. Sally is our daughter. She likes blue very much. Now she is in her blue dress. My father's name is Robby. My mother's name is Diana. They are old and they don't work now. I have a brother. His name is Robert. He is a worker, too. My wife's father is Sam. Her mother's name is Rose. Her sister is Lily.

    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!

    One day a man found a cocoon (茧) of a butterfly in the forest. He sat there for several hours and watched the butterfly. Suddenly a small opening appeared, and the butterfly made its great effort to force its body through that little hole. Then it seemed to stop making any progress. It appeared as if it had gotten as far as it could and it could go no further.

    So the man decided to help the butterfly. He cut off the remaining bit of the cocoon so that the butterfly could come out easily. But to his surprise, the butterfly got a heavy body and very small wings when it came out of the cocoon.

    The man continued to watch the butterfly because he expected that the body would grow smaller at any moment and the wings would become larger and be able to fly. But neither happened! In fact, the butterfly spent the rest of its life crawling (爬) around with a heavy body and small wings. It was never able to fly.

    The man was in his kindness, but he did not understand the nature rules. Before the butterfly came out of the cocoon, fluid (流体) from its body must be forced into its wings, and then it would be ready for flying. It must have a hard struggle (拼搏) to get through the small opening to get its freedom from the cocoon.

    Sometimes struggles are exactly what we need in our life. If God allowed us to go through our life without any difficulties, it would make us fail. We would not be as strong as we could have been; we could never fly.
