It's Sunday morning. The students of Class 3 are giving their classroom a good cleaning. Miss Huang, their teacher, is working with them. The children are busy. Some are carrying water, some are cleaning the windows, others are sweeping the floor. Zhang Hua is putting up a map on the wall. It is a map of China. Wang Fei and Wei Qing are mending some broken chairs. The children are listening to the radio while they are working. The classroom looks nice and bright after the cleaning. The children are very happy. They go home for lunch at noon.

    Amy and Tom are going to have a busy day next Sunday. In the morning, Tom is going to visit his aunt and Amy is going to buy a cat in the pet shop. Tom is going to have lunch with his aunt. After lunch, Amy is going to borrow some magazines and story books in the library. Tom is going to buy a dictionary and a new CD in the bookstore. Finally, Amy and Tom are going to buy some apples and go home by subway together.

    I'm Sally. I live in a nice and a clean place. There are many trees and flowers. There is a tall mountain. A river is between a mountain and a forest. In the forest, there are many animals. I can see birds, ducks... I always play near the forest. I love the place.

    This is Billy and his sister's bedroom. It's not big, but is tidy and clean. There are two beds in the room. There is a desk between the beds. There are some books on the desk. Some are English books. Some are Chinese books. There is a phone on the desk.too. There are two chairs near the desk. One is for Billy, and the other is for his sister. There is a map of America on the wall. There is a map of the world on the wall, too. Billy and his sister like their bedroom very much.

    Many years ago, people use a stick, a large piece of wood and dry leaves to make a fire. Today, wood, gas (煤气) and electricity (电) can all make a fire. I think wood is the most dangerous. And I like gas most because it's easy.

    People use fire in many ways. At home, people use fire to cook food and boil water. In factories, workers use fire to melt (熔化) metals (金属) to makes things of different shapes. Some workers use fire to make glass.

    Fire can help us to do many things, but sometimes fire is dangerous. Cigarettes and campfires can all start a fire in the countryside, in schools and at homes. We must be careful. We mustn't smoke in the countryside, and we mustn't cook without an adult (成年人). We mustn't play with matches. We mustn't play around a fire.
