Nearly all our food comes from the soil. Some of us eat meat, of course, but animals live on plants. If there were no plants, we would have no animals and no meat. So the soil is very necessary for life. The top of the ground is usually covered with grass or other plants. There may be dead leaves and dead plants on the grass. The waste matter (糞) from animals also falls on it.

All soil needs food. If we do not give it any, the plants will be weak. Farmers found that animals’ waste is the best food for the soil, but chemical fertilizers (化肥) are also very useful. The same crop (莊稼) should not be grown in the same place every year; it’s better to have a different crop. A change of crop and the use of a good fertilizer will keep the land good.

1.What would happen first without plants?

A．People would have more crops.            B．Animals would die.

C．There would be more food.                D．There would be less soil.

2.What does the writer tell us in the first paragraph (段落)?

A．Leaves, plants, grass and waste live on each other.

B．There would be no animals without meat.

C．There would be no plants without animals.

D．People, animals, plants and soil live on each other.

3.Which is the best food for soil in the field?

A．Chemical fertilizers  B．Plants and grass.    C．Animals’ waste.   D．Different crops.

4.Why do we often grow a different crop in the same place every year?

A．Because we can keep the soil rich this way.

B．Because we don’t have enough land.

C．Because we want to have a different food.

D．Because we do this as a habit.

5.What is the best title for the passage?

A．Soil and Waste     B．Plants and Animals   C．Food and Waste    D．Soil and Food
