    A long time ago, there was an emperor. He had a beautiful garden. In the garden, there was a little nightingale(夜莺) singing very beautifully.

    One day, the emperor heard about this little bird's beautiful voice. He asked his guards to bring her to him. As soon as the emperor heard the nightingale's voice, he said, "Put her in a golden cage, so she can stay and sing for me whenever I want to hear her sing."

    The little bird was so unhappy about being kept in the cage that she stopped singing one day. The emperor was very angry. He ordered the scientists in his palace to make a robot bird for him. The bird could sing very beautifully, too. The emperor was pleased.

    Soon the robot bird became old. It no longer sang beautiful songs. Just at that time, the emperor became very weak. One morning, while lying in bed, the emperor wanted it to sing once again. But the robot bird couldn't sing any more.Suddenly the nightingale landed on the window. She began to sing her most beautiful song. The emperor was very happy! He became better and better each day.

    After the emperor was well, he changed a lot and became kind to his people. From then on, all his people cherished(爱戴) him for his love and kindness.

    Once upon a time, a fox was walking along a road, he saw some beautiful grapes hanging a high wall. He stopped to look at the grapes. They looked nice to eat. The fox wanted to eat the grapes very much, but he couldn't reach them. So he jumped and jumped until he was very tired.

    Finally he stopped jumping and walked away with his nose held high. He said, “I don't need those grapes. They look nice but I'm sure they are sour."

In our daily life, when people can't get something they want, they may say, "The grapes are sour.”

    Hi! I'm Maria. I have two boys. Tom is three years old and Tim is one year old. My family moved into an apartment a few months ago. Our house is on the second floor. But our neighbour downstairs complains at least once a day and we have got her note, saying "Please stop running and jumping on the floor."

    Since then, I have to do everything to keep the boys busy or out of the apartment during the day, but this can't stop my kids from making noise. They are just children under the age of four. Now the lady downstairs often bangs the walls when my boys run and jump in the rooms.

    However, she often plays movies loudly late at night. The noise wakes up my children at night and makes them cry.

    At the same time, we have another problem. The person on the third floor often walks too hard and wakes up my boys at 5:30 a.m. , but I think we have to face it.

    Usually my boys are sleeping from about 8:30 p.m. to 6:00 a.m. the next day. At least they don't annoy the neighbour downstairs during the hours.

    Thomas Alva Edison is one of the greatest inventors of all times. One of his most famous achievements is the electric light. He tried thousands of times to make a long lasting light bulb (灯泡). Although the light bulb is not his invention, he is the only one to have made such a successful light bulb. Many people remember him for the invention of the electric light. He held a lot of patents (专利权) worldwide. Many of them were approved (批准) in USA.

    We can find his inventions in many fields. In fact, many of the advanced inventions were based on his ideas. He invented a phonograph (留声机), a film picture camera, a ticket recorder and so on.

    Edison was not a good student at school. But he loved to do new experiments. When he was still a child, he built his first lab to perform his experiments.

    An amazing story of Edison's childhood is that he almost made his servant die. Edison used to think that birds ate insects and these insects might make them fly. So, he collected these insects and blended them to make juice. He then let his servant drink the juice. After drinking the juice, the girl lost her sense. But luckily, she was saved.
