    Fifteen hours is a long time to be on a plane, but you know, Africa is a long way from America. Finally, we're in Namibia, a country in southwest Africa. Namibia is about one size of California. However, it is home to just over two million people. And the country's main airport is 45 kilometers east of its capital, Windhoek.

    Now we are in a wildlife park. We will spend five days finding ways to protect this area's wildlife. At the moment, my wife and our two kids are enjoying some local dishes. I'm talking with workers in this park. I'm so much looking forward to the following days!

    Yesterday morning, I had nothing to do. So I went to visit the Eiffel Tower, a symbol of Paris. It was my first time there, so I took a lot of photos.

    Finally, the big moment came! A lot of artists came to watch my show. It was a great success. After the show, I attended a big party. It was great, but I felt so sleepy after it.

    When I got back to my hotel, it was already1:15 am. I went to bed without washing. I just needed a good rest before my two—hour journey home by plane.

    Linda was a sixteen-year-old girl in Canada. She was feeling bad for several days. Her mother took her to a hospital and the doctors found out that she had cancer(癌症). Linda's life changed. She began to go to the hospital often for treatment(治疗), and she also became depressed.

    The hospitals and the doctors were good, but Linda did not have hope herself. Linda's mother called a flower shop close to the hospital. "I want some beautiful flowers for my daughter. She is a teen girl with cancer. "She told the shop owner.

    Later, the flowers arrived. Then Linda saw something unusual. It was a card. It read, "Linda, I own(拥有)this flower shop. I had cancer when I was fifteen years old. I am 24 years old now. Good luck. My heart goes out to you.

Yours,

Alice

    Linda smiled. She finally felt some real hope. She found the will(意志)to live. Little things make a big difference. All of us can give little things like kindness encouragement and hope to others.

    "You have saved my horse." Queen Olivia told the young boy standing before her. "Now you shall get a gift for what you did." Peter nervously ran his fingers through his brown hair. That day when he was working in the field，the shocked horse ran past him. Without thinking，he rushed out and controlled it. He didn't know it was the Queen's horse and never expected to get a gift. But he still felt happy for getting one.

    Two of the queen's men appeared. One carried a mirror. Red jewels(珠宝)shone on top of the mirror's silver frame(框架). The other carried a wooden cage with a chicken inside it.

    "Only one gift call be yours," the queen said. "Choose wisely." "That's easy," Peter said. "I'll take the chicken." Some of the queen's men laughed. It was clear that they thought he had made a foolish choice.

    "And why did you choose the chicken?" the queen asked. "Well, I don't know much about jewels," Peter answered. "But I do know about chickens. The chicken will provide eggs for my family for a long while."

    Queen Olivia smiled. "Then you did make a wise choice," she said. "That minor may look beautiful. But the jewels you see are only colored glass, and the frame is painted silver. The chicken is much more valuable." Peter took the chicken and bowed. "Thank you, your majesty."

    "You are a smart child." the queen added. "I could use a smart boy to help take care of my horses. Would you like to take the job?" Peter smiled. "Thank you very much!" he said excitedly. A job at the castle paid well. Now his family wouldn't worry about their food any more--all because he was kind to help others and smart enough to make the right choice!

    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 mall might have thrown the dish away. But Fleming was very careful and smart. He understood what the mold did. How lucky the humans were!
