5、 阅读下列短文，回答题。
Look at the slopes(斜坡) of a hill on a rainy day. You will see many streams of muddy(泥泞的)water running down the slopes. The water is muddy because it washes away soil from the hill slopes.
When the soil is carried away by water we say that the soil is being eroded.
Loss of soil takes place most easily on hill slopes. Rain water runs down slopes quickly and carries plenty of soil with it. Loss of soil can also take place on flat, open land.
Plants cannot grow on such land because there is not enough soil on it to give them the things they need. Plants need water and salts from the soil.
One way of stopping loss of soil on flat, open ground is to grow small plants such as grasses.
These plants are called cover crops. Their roots hold the soil tightly together. So the rain water cannot wash away the soil.
Loss of soil on slopes can be stopped in a number of ways. One way is to cut a slope into "steps"called terraces, so that water carrying soil cannot run straight down the slope. It has to run down the terraces. This slows down the flow of the water. Most of the soil in the water is left behind on the terraces. Water can carry away the soil only if it is flowing fast. In this way, the soil washed away from the upper part of the slope will be left on the terraces. The edges of the terraces can also be raised.
These will hold back the rain water and the soil it carries.
Loss of soil might happen when__________.
A．it rains
B．the soil is muddy
C．there is plenty soil
D．there is a stream
