What will the house of the future look like? Could it have gardens on its walls, or a pool with fish for dinner? Architects(建筑师) believe that they are all possible. The only thing for sure is that the houses will be as green as possible.

    I arrived in the UK last weekend to learn English. So far I have already made a few friends and had some traditional English food there. But after having three days of hamburgers, sandwiches and potatoes, I thought none could be more delicious than Chinese food , especially my favorite—huo guo. You can't imagine how excited I was when I got to know that there was going to be a free meal of hotpot to welcome the new students. On the way to the canteen, I seemed to smell huo guo in the air.

    To my surprise, when I went into the room I didn't see any of huo guo. Where was it? With many questions in my mind, I sat down to have the free meal. After talking with an English girl, I got to know that Chinese huo guo is completely different from hotpot. Chinese huo guo is written in two words—hot pot, and hotpot, one word, is a traditional English dish.

    Hotpot is made from mutton and onion. On the top are pieces of potatoes. People put it in the oven all day in a heavy pot on a low heat. It takes very little effort to prepare. You can often see it at parties in the UK because it's easy to prepare for a large number of people and is not expensive.

    Hotpot doesn't taste bad. However, I still miss huo guo—hot pot, two words!

    Miss Evans was going to give a speech on Friday afternoon. But on Thursday night she was told that she had to go to an important meeting the next day at the same time. "No one can be in two places at the same time. What should I do?" She thought. But soon, she had an idea.

    At five to three on Friday afternoon, Miss Evans went to the lecture room. There were twenty students waiting for her. "I'm sorry," she said, "I won't be able to give my speech today." The students looked surprised. Miss Evans explained that she had an important meeting. "However," she went on, "though I can't be with you myself, my voice can." Then she put a small recorder on the desk," You see, I've recorded my speech and you can listen to it without me." Miss Evans turned on the recorded and left.

    The meeting ended a little early. Miss Evans decided to go back to her students. She stood for a moment outside the room, listening to her own voice. Then she opened the door. To her surprise, the room was empty. As she looked around, she saw a number of small recorders "listening" to her speech!

    "Well." she thought, "If I can be in two places at the same time, why can't they?"

    The famous scientist and thinker, Charles Darwin, was born on February 12, 1809.As a boy, Charles liked to go for walks in the fields and forests. He enjoyed watching nature, and comparing what he saw with everything he had read in science books. He also liked collecting very much. He collected many things, such as birds, eggs, stones and leaves.

    At sixteen Darwin was sent to the University of Edinburgh to become a doctor. But he was interested in the history of nature.

    Then he was sent to study in the University of Cambridge. There he studied until 1831.

    Some time later he heard that the ship Beagle was going on a trip to South America and wanted a scientist. His teacher advised him to go. So when the Beagle left England in December, 1831, Darwin was on it.

    The trip lasted almost five years. Darwin saw many new plants and animals. He collected all kinds of plants.

    In 1842 Darwin went to live in Kent, and there he continued his studies of change in nature. Darwin understood that plants and animals are not always the same, and that they really change.

    By 1859 Darwin had finished his famous book The Origin of Species. It made a great hit in the world of science. He was opposed(反对)by the church and even by some scientists. But later, more and more scientists agreed with him.

    In1871 Darwin wrote another important book. Darwin continued his studies in science until he died in 1882.

    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 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 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.
