Mr. Smith made many tests with different animals and the monkey was the cleverest of all the animals.

      One day Mr. Smith put a monkey in a room. He also put some small boxes in it. In one of the boxes there was some food. "How long will it take the monkey to find the food?" Mr. Smith said to himself. "Let me wait and see." He left the room and waited outside. Three minutes later, he put his eye to the keyhole. What did he see? He saw the eye of the monkey. The monkey was on the other side of the door and looked at Mr. Smith through the keyhole.

    On Monday, I stopped my car in front of my daughter Juliet's middle school. She jumped in the front seat, feeling down. She asked me to help her study for her science test.

    "Dad I need to memorize a unit about the Reproductive Cycle of Plants. And I can hardly make it."

    "You know memorizing seems like the best way to study, but in fact you can do better in tests if you work on trying to understand the material."

    Juliet was open to my advice. It was Monday afternoon and we had two nights to study before the test on Wednesday. I suggested a plan. "Tomorrow night, you are going to teach the material to me. Tonight, read the unit. Prepare to teach."

    Asking her to teach me was an unusual idea but I was determined to do it. Studies show teaching somebody else is a very useful way to lean, Even if you don't do the teaching, the act of preparing to teach leads to more learning than just trying your best to memorize the material.

    On Tuesday afternoon, Juliet sat down with her Science book facing me said, "Okay Dad, let's study." I wanted her to teach me. But false starts happened. I couldn't be too hard on her. So instead we starred with me asking her some simple questions. She knew some but not other. When she didn't know the answers. I encouraged her to check the book.

    She started checking things that didn't make sense. And she was actively seeking to test her understanding. I was happy to see it. She wasn't memorizing, she was trying to make sense of things, which was exactly what I had hoped she would do.

    Driving a car at high speed along a highway seems to be fun. You need only to follow the bright traffic signs beside the highways and it will take you to where you wish.

    But to a London taxi driver, driving is not an easy job. A taxi driver has to have not only good driving skills but also a good knowledge of the city of a London, from the smallest lane(小巷) to the most popular bar around. He has to be at the service of all kinds of passengers at all times.

    A certain London taxi driver told of his job as follows.

During the night it is quite usual for him to stop two or three times for some refreshments (点心). He said. "I never drink when I'm working —- I would lose my licence"

    He normally goes home between 2 and 3 O'clock in the night. There are times he has to stay longer and try to make more runs. He said, "That's the worst thing about working for yourself. If you don't make the money, no one is going to give it to you."

London taxi drivers not only 'take' but also 'give'. Every summer hundreds of children from London will go for a day at the sea— by taxi! Their rides are paid by the taxi drivers, and these fares(车费) all go to the 'London Taxi Fund for Underprivileged Children. At the sea, they are met by the mayor, and a lunch party is also held in honour of the taxi drivers and the children. After a happy day running around the sea beaches and visiting the market, the children go home again-- by taxi, and free of charge, of course!

    This morning Tom gets up at 6:00. Today his family is going to move(搬家)into a new house.

    Tom and his family are busy putting their things into some boxes. When Tom helps to put some glass cups into a box, he breaks one of them. He hurts(使受伤)his right hand. Mum tries to find some Band-Aids(创可贴) for him. But she forgets where the Band-Aids are. So she has to open the boxes one by one. Dad comes quickly to help them. But he falls over. He hurts his hand, too. At last they find the Band-Aids in one of the boxes. Most of the boxes are open now. The family have to pack(打包)them again。

    There are so many boxes in the house. Dad puts some of them behind the door. Later, some friends come and they help to move all the things onto the truck.

    In the new house, Dad starts to count the boxes. One, two, three, four…There are only twenty boxes.

    Where is the last box? Is it behind the door of their old house? They don't know.

    During the time of Jin Dynasty, there was a man named Le Guang. One day, Le Guang asked one of his friends to have dinner at his home. After dinner, his friend was back.

    For a long time, his friend didn't come. Then Le Guang heard that his friend was ill, so he came to visit him. Le Guang asked him what was wrong with him. His friend answered, "Last time, at your home I found a little snake in the glass and I was ill after I drank the alcohol (酒)." Le Guang was very surprised because there wasn't a snake in the glass. Suddenly, he remembered there was a bow (弓) on the wall. There must be the shadow (影子) of the bow which looked like a little snake.

    So Le Guang asked his friend to join him for a drink again. When the glass was full of alcohol, he pointed to the shadow of the bow in the glass and asked his friend to have a look. His friend shouted, "That is what I saw last time!" Le Guang laughed and took away the bow.

    "Can you see the snake now?＂ he asked. His friend was surprised to find that the snake was gone. After his friend knew the truth, he was well.

    For many years, this story has been used to advise people not to be too suspicious (怀疑的) easily.
