The story is about a young student. She worked very hard at her lessons. She worked so hard that she became ill. She couldn't go to sleep at night. When she got up the next morning, she felt very tired.

    So she went to see a doctor. Hearing the student's words, the doctor said, "You are too stressed out. You must eat more food like vegetables and tofu. Besides you can try to count(数) numbers when you are lying in bed. By the time you reach one thousand, you will be asleep. I'm sure of it."

    The next day, the student came to see the doctor again. "Well," said the doctor, "how are you feeling today?"

    The student still looked tired. "Yes," she said, "I tried to count one, two, three, four... up to one thousand. But when I reached five hundred and sixty, I feel sleepy. I had to get up and drink some coffee so that I could go on counting up to one thousand. But then I still couldn't be asleep."

    Mr. Green made a robot. He could say only one sentence—“There is no doubt (疑问) about it.” The robot always repeated the same words when you spoke to him.

    One day, Mr. Green needed lots of money and he took the robot to the market to sell him. “Who will buy my robot? He is very smart,” he shouted, “Twenty thousand dollars for my robot!”

    A man was surprised that he was asking for so much money. Instead of asking Mr. Green why he wanted so much money, he decided to speak to the robot. “Are you worth (值) twenty thousand dollars?” he asked the robot. “There is no double about it,” answered the robot.

    The man liked the robot's answer so much that he bought him and carried him home. But very soon he found that the robot could say nothing else. He was sorry he bought the robot. He stood in front of the robot and said, “How foolish I was to throw so much money away！”

    “There is no doubt about it,” said the robot.

    Henry was an office worker in a big city. He worked very hard and enjoyed travelling during his holidays.

    He usually went to the seaside, but one year he saw an advertisement in a newspaper." Enjoy country life. Spend a few weeks at West Hill Farm. Good food. Fresh air. Walking. Fishing. Cheap and interesting."

    "This sounds a good idea," he thought. "I'll spend a month at West Hill Farm. I think I can enjoy walking and fishing. They'll make a change from sitting by the seaside and swimming."

    He wrote to the farmer. In the letter he said that he would like to spend the whole July there. Then on the first day of July, he left for West Hill Farm.

    But four days later, he returned home.

    "What was wrong with West Hill Farm?" his best friend, Ed. asked him. "Didn't you enjoy country life?"

    "Country life was very good," Henry said. "But there was another problem."

    "Oh. What?"

    "Well," he said, "on the first day a sheep died, and we had roast mutton (烤羊肉) for dinner."

    "What's wrong with that?" Ed asked. "Fresh meat is the best."

    "I know, but on the second day a cow died, and we had roast beef for dinner."

    "Lucky you!"

    "You don't understand," Henry said. "on the third day a pig died and we had roast pork for dinner."

    "A different kind of meat every day," Ed said loudly, "and you are complaining!"

    "Let me finish, "Henry said. "on the fourth day the farmer. died, and I didn't dare (敢) stay for dinner!"

    A man was visiting a rich person's house. As he went along, he saw a box of apples on the side of the road. He said, "I do not want to eat those apples. The rich man will give me very nice food to eat." Then he took the apples and threw them away in the dust(尘土).

    He went on and came to a river. The river had gotten so high, and he could not get through it. He waited for some time and said," I cannot go to the rich man's house today, for I cannot get over the river."

    He started to go home. He had eaten no food that day. And he was very hungry. He came to the apples, and he was glad to take them out of the dust and eat them.

    Do not throw good things away. You might be happy to have them later.
