We know the air is very important for us. Without air, we couldn't live. Other creatures can't live either. We need clean air. The dirty air is bad for us. Now the air pollution is very serious in some places. For example, the smoke from some factories make the air dirty. Exhaust gas from cars make the air dirty. The forest fire can make the air dirty, too. So we need to pay attention to the air pollution. We can plant more trees and think of other ways to sovle the problem.

    Mr. Brown lived in a small town, but he worked in a big city. So he moved there with his wife and two children last Tuesday. On the next day, Mr. Brown took his new car out and was washing it. When a friend came, the friend stopped and looked at the new car for a minute. Then Mr. Brown turned and saw him. The friend said, "That's a new car. Is it yours?" "Sometimes. "Mr. Brown answered. The friend was surprised slowly, "Well, when there's a party in town, my daughter, Jean drives it. When there's a football game, it's my son Joe's turn. When I have washed it and it looks really nice and clean, my wife Linda uses it. And when it needs cleaning, it's mine!"

    My name is Jack. This is my home. I live in a cave.

    This is our living and dining room. My family share stories and eat here. Look! My father is telling us about his hunting today. My mother is setting up the fire. We cook here, so there is our kitchen too!

    We have a garden outside. My sister is picking up branches for our fire.

    We have two small caves inside our cave. They are our bedrooms. I share(分享)a cave with my sister.

    What is this? Oh, a bear is sleeping in my cave! It happens all the time in winter!
