Question

　　 Forests are large pieces of land covered with big trees. They are found all over the world, espe-cially in places where there is enough sunshine and much rainfall. Many kinds of materials (材料) come from forests. To build a house, we need wood for doors and windows, Beautiful chairs and tables are also made of wood.

　　Teak (柚木) wood is very useful for ship-building. It is used for all parts of a ship where wood and metal come in contact (接触) for it has a kind of oil to keep metal away from rust (铁锈). It can also stop the attack of white ants (蚂蚁) and other insects. For this, teak wood is an important railway building material.

　　Forests are no less important than useful. They are the home of wild animals. Without them, those animals would run among the places where we live and work. There would be no peace for man.

　　Forests are helpful to weather, too. When it is very hot, they can be a very good place for people to stay away from the sun. In winter, they can keep us from the cold. Forests and also stop the land from being washed away by heavy rain for trees hold the soil together. So it would be foolish to cut clown trees freely.
