Birds protect（保护）themselves by always listening and watching out for danger．At the smallest sign of it，they will fly away．Birds that cannot fly are often able to swim fast，or run quickly．Some birds make themselves look bigger and more dangerous by fluting（抖动）their feathers（羽毛）．

Another important protection for many birds is their color．Their feathers often have colors that match（和…相称）the things around their nests（巢）．Some birds change colors with the seasons．In the winter they are white to match the snow．In the summer they are brown to match the ground．

People sometimes kill birds without meaning to．When people cut down forests to build houses and factories，they destroy the homes and food of birds．If the birds have nowhere else to go and nothing to eat，they will die out．

Pollution may cause some birds to die．Birds that eat fish from polluted water get poison（毒）in their bodies．Then they cannot lay healthy eggs．New birds can’t be born．

Now people protect birds by passing the laws（法律）to control hunting（控制打猎）and pollution，by setting up some special parks where all the birds are safe from hunters，and by teaching people to care about birds rather than kill them．

The earth at the gate of their home kept the rain   6   and they were   7   again moving the earth away. It was very late, but they were   8  working hard.

　　Scientists are trying to make the deserts（沙漠）into good land again. They want to bring water to the deserts, so people can live and grow food. They are learning a lot about the deserts. But more and more of the earth is becoming desert all the time. Scientists may not be able to change the desert in time.

　　Some places on the earth don't get very much rain. But they still don't become deserts. This is because some green plants are growing there. Small green plants and grass are very important to dry places. Plants don't let the hot sun make the earth even drive. Plants don't let the wind blow the dirt（泥土）away. When a little of（一点儿）rain falls, the plants hold the water. Without plants, the land can become a desert much more easily.

(　　)(2)It is good to get rid of（消除）the grass in the desert

(　　)(4)It's important for us to plant trees and protect（保护）forests.
