     Shu Pulong has helped at least 1000 people bitten by snakes. “It was seeing people with snake bites that led me to this career,” he said.

In 1963, after his army service, Shu entered a medical school and later became a doctor of Chinese medicine. As part of his studies he had to work in the mountains. There he often heard of people who had their arms and legs cut off after a snake bite in order to save their lives.

      “I was greatly upset when they told me the story of an old farmer I met. It was a very hot afternoon. The old man was pulling grass in his fields when he felt a pain in his left hand. He at once realized he had been bitten by a poisonous snake. In no time he wrapped（缠绕）a cloth tightly around his arm to stop the poison（毒）getting to his heart. Running home he shouted, `Bring me the knife' Minutes later the man lost his arm forever.”

“The heartbroken story touched me so much that I decided to devote myself to helping people bitten by snakes.” Shu added, “I worked very hard and tried my best to make a good snake doctor.” And at last he made it.

    Some people remember the things by writing notes to themselves. Then they leave the notes in obvious(明显的) places, such as on the table or on the floor in the middle of the living room. I don't think I like to write notes to myself. Most of the time I lose them or forget to look at them until it's too late. I prefer to use an alarm clock to tell me what I should do. I have ten alarm clocks in my house. They could tell me about things. For example, if I have to make a telephone call at a certain time, I'll set an alarm clock to go off a few minutes early and put the clock by the telephone. Or if I want to watch a certain television program, I'll set an alarm clock at the right time and put the clock on top of the TV set. I can remember almost anything if I use my clocks. However, sometimes an alarm clock goes off and I don't know what it means. I always remember setting it, but I do not know why I set it. If the clock is by the telephone, I know I may have set it to tell me to call someone, but I can't be sure. I might have set it to tell myself that somebody was to call me at a certain time.

    "The hound(猎犬)!" cries Holmes. "Come, Watson! Come."

    We run quickly over the moor(荒野). We hear one last cry. A man is lying on the ground. As we approach(靠近) we see the dead body of Sir Henry Baskerville. He is wearing his brown suit.

    "Oh, no!" says Holmes, "This man has a beard!"

    Indeed Selden is dead instead of Sir Henry.

    "So it is all clear to me. I remember that Sir Henry gave his old suit to Barrymore, and Barrymore probably gave it to Selden—his wife's brother."

    "Then Selden is dead because of this suit," says Holmes.

    "Think, Watson! Someone gives the hound some of Sir Henry's clothes—probably the boot from the hotel in London. The hound picks up Sir Henry's scent and runs after this poor man."

    Suddenly we see Stapleton walking towards us. He says, "There was a strange noise. I was worried about Sir Henry. I wanted to check if he was all right."

    "Really?" asks Holmes.

    Stapleton looks at Holmes. "Why, it is Mr. Sherlock Holmes, the famous detective! Can you solve the mystery of the Hound of the Baskervilles?"

    Holmes shrugs his shoulders," We cannot solve every mystery. Anyway I will return to London tomorrow."

    "Oh, will you return to London tomorrow?"

    "Yes."

    So Holmes and I walk off to Baskerville Hall and Stapleton walk to his home.

    Holmes thinks Stapleton is dangerous. But we have no proof that Stapleton is the murderer.

    "There are no marks on Sir Charles's body. We know that he died of fright, but we can't prove anything."

    "Things are becoming clear to me," Holmes says to Sir Henry. "It's a very difficult case. And you must help me to catch this hound."

    We are surprised to see one portrait(画像) of a thin man is Sir Hugo, the first victim of the Hound of the Baskervilles. And he's like both Sir Henry and Stapleton. "Stapleton is a Baskerville," replies Holmes. "So he wants to inherit(继承) the Baskerville fortune, and he…," I say. It's an important clue.

    There is an old man in a house. In the house there are many mice. The old man has a cat. Every day the cat catches the mice and eats them.

    One day, the old mouse says, "All mice must come to my room this evening. We must find a way to deal with (对付) the cat."

    All the mice come. Many mice speak, but they don't know what to do. At last, a young mouse stands up and says, "We must put a bell (铃) on the cat. When the cat comes near, we can hear the bell and run away. So the cat can't catch us." "Who can put the bell on the cat?" asks the old mouse. But no one answers.
