A farmer had a cow. He took very good care of this cow and one day when it was ill, he was very worried. He telephoned the vet.（兽医）

  “What's the problem?” The vet asked him when he arrived.

  “My cow's ill” the farmer said. “I don't know what the matter with her is. She's lying down and won't eat. She's making a strange noise.”

The vet looked over the cow. "She's certainly ill," he said, "and she needs to take some very strong medicine."

    He took a bottle（瓶子） out of his box, put two pills（药丸） into his hand and said, "Give her these. The pills should make her better” How should I give them to her?” the farmer asked.

    The vet gave him a tube (管子)and said, "Put this tube in her mouth, then put the pills in the tube and blow. That will make it."

    The next day the farmer sat outside his house and looked more worried.

   “How's your cow?” the vet asked.” No change,” the farmer said, “and I am feeling very strange myself. I did what you said, I put the tube(管子) in the cow's mouth and then put two pills down it.” And?” the vet asked.” The cow blew first, and blew the pills to my mouth.” the farmer said.

    Some of the greatest problems we face today are the destruction (破坏) of our environment． Brown clouds, polluted water, endangered wild animals．．, these problems seem so huge．

    So my family does what we can． We take cloth bags to stores instead of using plastic bags． We walk where we don't have to drive．．．

    But does it do any good? When I am the only one in line at the market with cloth bags, am I doing any good? Does my walking to stores make any real difference to the world?

    I recently learned something about flamingos (火烈鸟) which like to get together in groups of a thousand or more． Every year, when the time comes for migration (迁徙), a few of them first takeoff from the lake． But none of the others seem to notice, so the small group returns．

    However, the next day they try again． This time few more fly along with them, but most of them still pay no attention, so they return again． They try for several times． Every time a few more birds join in but, since the thousands of others still take no notice, the great migration plan is once more stopped．

    Then one day something changes． The same small group of birds once again starts flying and a small number more join in just as before, then more． Finally, they all take flight and the migration really begins．

    What a spectacular sight it must be—thousands of flamingos taking off into the sky at once!

    A few can make a difference． Even if you're the one to take the first step, and continue trying, others will someday take notice and together we will solve even our greatest problems．

    How much do you know about Albert Einstein?

    Albert Einstein, born on March 14, 1879 in Germany, was a great scientist in the world. ①He was strange because he hated haircuts and new clothes. He believed in peace. All his life, he hated war. However, his most famous idea, E = mc², helped create the world's most dangerous weapon (武器). Many people think he was the smartest person in the world. But Einstein said that he thought like a child with many questions and unusual ideas.

    What did he like?

    Einstein liked learning sailing (帆船运动). He sailed in small boats all his life. He once joked, “Sailing is the sport that takes the least energy!” When Einstein was a child, his mother made him take violin lessons. At first, he didn't like the violin. But then he learned to love music and became a good violinist.

    Later, he said, “②热爱是最好的老师。”

    Why is the sky blue?

    In 1910, Einstein asked a question which many children often ask, “Why is the sky blue?” After his careful research, he answered the question like this: “It's because light is made up of many colors including blue. When light travels to Earth, gas particles (气体微粒) spread the blue light all over the sky.” His answer is true in physics.

    I' m ready to do my first jump 10 months after a skydiving (特技跳伞) accident. I can't wait! That accident almost killed me and it made me stay in hospital for half a year. During the boring long days, I didn't feel glad to be alive. I was wondering how I could live without my favorite sport.

    It all started one evening after a nine-to-five day. I was sitting on the sofa when an ad (广告) came on the television. "Try skydiving," it said. The next day, I went to the skydiving school in my town. At the end of the day's lessons, I knew I found the fight sport for me.

    I will never forget my first jump. Five of us walled to the runway and got into a plane. I was scared, but the others were tailing and joking, and I started to feel a little relaxed. It was a beautiful, cloudless day and the sun was just going down. Soon it was time to jump. As I jumped from the plane, I shouted. But then everything became quiet. It was the most wonderful four minutes of my life.

    From the first jump, I was hooked. I started spending all my free time skydiving . It became my reason for living. Things were going really well. Then an accident happened on my 104th jump. I broke my both legs, right arm and nose. I stayed in hospital for six months, but I still couldn't forget skydiving.

    My mother couldn't understand why the only reason I wanted to get better was to go skydiving again. But for me, skydiving is life, and life is skydiving.

    Do you know any 9-year-olds who have started their own museums? When Theodore Roosevelt was only nine, he and two of his cousins opened the "Roosevelt Museum of Natural History". The museum was in Theodore's bedroom. It had a total of 12 specimens. On display were a few seashells, some dead insects, and some birds' nests. Young Roosevelt took great pride in his small museum.

    Born in New York in 1858, Theodore Roosevelt was not always healthy. "I was a sickly boy", he once wrote. Roosevelt had a health condition called asthma. He often found it hard to breathe. Instead of playing, he watched nature and then read and wrote about it.

    Roosevelt's interest in nature sometimes got him into trouble. Once, his mother found several dead mice in the icebox. She demanded that the mice be thrown out. This was indeed "a loss to science", Roosevelt said later.

    Because Roosevelt was often sickly as a boy, his body was small and weak. When he was about 12, his father asked him to improve his body. Roosevelt began working out in a gym. He didn't become strong quickly. But he did decide to face life's challenges with a strong will. That determination stayed with Roosevelt his whole life. And eventually his body did get strong. As an adult, he was an active and healthy person. He enjoyed adventures, and he loved the outdoors.

    A toy company named the teddy bear for Theodore "Teddy". After knowing that, Roosevelt refused to shoot a baby bear while hunting.

    In 1900, at the age of 41, Roosevelt was elected Vice President. A year later, President McKinley, was shot and killed. Roosevelt became our 26^th President. At 42, he was the youngest leader the country had ever had.

    One day, a little monkey and a little fox(狐狸) went out to play. They saw an apple tree on the other side of the river. There were many big and red apples on it. But there was no bridge over the river. The monkey thought(想) hard and had an idea. They pulled down(推倒) a tree and put it over the river as a bridge.

    The monkey said, "My old friend, you go there first." But after the fox went to the other side, he kicked(踢) the tree into the river and ran to the apple tree. "How can I get there without the tree?" cried the monkey. The fox laughed and said, "You just stand there and watch me eating the apples." The monkey was very angry.

    Suddenly it began to rain. The water level(水位) in the river rose（上涨） and tree flew away with the water.

    "You can eat all the apples. But you can't come back," shouted the monkey.

    The fox stopped eating and looked at the monkey sadly.
