My mother and I are in the shop(商店). We'll buy(买)some fruit. There are many apples, bananas, oranges, pears and watermelons. How much are they? Four yuan for a kilo(千克) of apples. Two yuan for a kilo of bananas. Three yuan for a kilo of oranges. Five yuan for a kilo of pears. One yuan for a kilo of watermelons. We'll take some.

    Look at Tom's room. What a mess(乱七八糟)! His books are on the floor. His shoes are on the desk. A kite and some clothes are in his bed. Tom's mother comes to help him. She put the books away and says,"Look, your pencil box is under the books. You must take good care of your things."

    Don't throw things out of the window. It's dangerous. You might hurt someone. Don't cook here. It's dangerous. A small fire can become a big one. Be careful! Look out for cars. Don't go against the traffic. Don't open the door for a stranger. It's dangerous.

    We are living a happy life. Our parents love us so much that we can have what we want. But some of our classmates do not take good care of these things. They throw away their pens and paper. Some of them even waste food. I think it is a bad habit. We should protect environment of the school and the city. We shouldn't step onto the grass, and we shouldn't pick the flowers. Try to go to school by bike or on foot. Don't use plastic bags. Every year we can plant many trees, the environment will be better and better.
