If we read newspapers, we’ll learn that the forests on the earth are getting smaller and smaller all the time. We are cutting down large numbers of trees because we need wood and farmland. Some scientists say that there will not be any great forests in 20 or 30 years.

What will happen if the forests disappear? A lot of plants will die and the animals will lose their home. In many places the new farmland will soon look like the old deserts. Crops（农作物）will not grow there. There won’t be enough rain, and the weather will get hotter and drier. If the weather changes on the earth, life will be hard for everyone. Our living environment will be become worse and worse. More and more rich farmlands will disappear.

No one has ever proved(证明) that animals can really talk. However, a famous parrot(鹦鹉) called Alex was trained to speak.

Other birds can use different noises or songs when they are in danger or want to make friends, but they cannot make human sounds.
