科目：初中英語 來源： 題型：

 All our food comes from the soil. Some of us eat meat,but most animals live on plants. If there are no plants,we should have no animals and meat. So the soil is necessary for life.

 The top of the ground is usually covered with grass or other plants. Plants grow in soil,which has a dark color. This dark soil is humus. Dead leaves,dead plants and animal waste make it,but this takes a long time. When the humus has been made,plants can grow well in it.

 All soil needs food. If we don’t give it any,the plants will be weak. Animal waste is the best food for the soil,but chemical fertilizers are also very useful. The same crop should not be grown in the same place every year,and it is better to have a different crop. A change of crop and the use of a good fertilizer will keep the land in good condition.

 When the soil is dry,the wind blows it away. Sometimes heavy rain carries the humus down to the river. People should grow more and more trees and grass to stop wind from carrying the humus away. It takes hundreds of years to make humus,so we must save every bit of it. Without soil,where can we grow food?
