What is soil? It is the skin of the Earth. It supports all forms of life. Nearly all our food comes from the soil. Some of us eat meat, some of us eat vegetables, but most animals live on plants. If there are no plants, we will have no vegetables, no animals and no meat.
Plants grow in soil with a dark colour. The dark soil is humus(腐殖土壤). Dead leaves, dead plants and animals' waste make it, but it takes a long time. When the humus has been made, plants can grow well in it.
All soil needs food. Animals' waste is the best food for the soil, but chemical fertilizers(化肥) are also very useful. The same kind of crops should not be grown in the same place every year. A change of the kind of crops 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 a 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, how can we live?

The world is not only hungry, but also thirsty. Perhaps this s 1 strange to you, since nearly 70% of the Earth's surface(表面) is covered w 2 water. But about 97% of that is sea water, or salt water. Humans can only drink and u 3 the other 3%--the fresh water from rivers, lakes,

the underground and o 4 sources(资源). And we cannot even use all of that。 Even worse, some of it has been polluted.
However, as things stand today, this fresh water is still e 5 for us. But our need for water is b 6 larger and larger quickly--almost day by day. We should take action to do with this problem now and in this w 7 , we can get away from a serious worldwide water shortage(缺少) later on.
We all have to learn how to s 8 wasting our valuable water. One of the first steps is to improve ways of reusing it. Today in most large cities, water is used only o 9 and then sent into a sewer system (排污系统). From there it r 10 to the sea or runs into underground places.
