    The air is everywhere around us. Air has no colour. We can't see it. When it moves, we can feel the air. Air is very important to our lives. People and plants can't live without it. If there was no air, there would be no life.

    Aeroplanes can't fly without air. The air holds up the planes. We can't make fire (生火) without air. If you cover (盖住) a burning (燃烧的) candle with a glass. It will quickly go out (熄灭).

    Sound spread (传播) through the air. Without air, we can't hear.

    It was Sunday yesterday. We had a picnic in the park. We went there by car. There were so many people in the park. I saw some birds in the tree. They sang beautifully. Some old men did taijiquan under the tree. I played football with my friends. Then I was thirsty（口渴的）, so I drank some water. The girls played games. We were very happy.

Hello! I'm Mike. I am interested in space travel. Yesterday morning, I asked my cousin John to read a book about space travel with me. Then we made a model spaceship together. We liked it very much. At night, I had a dream. In my dream, our model spaceship took us into space. We travelled around the earth. We saw so many stars in space. How interesting! Suddenly (突然), my dog barked loudly. I woke up. Oh, it was a funny dream!
