听力原文： What is the best way to learn a language？ We should remember that we all learn our own language well when we were children. If we could learn a second language in the same way, it would not seem so difficult. Think of what a small child does. It listens to what people say and it tries to imitate what it hears. When it wants something, it has to ask for it. It is using the language, talking in it, and thinking it all the time. If people had to use a second language all the time, they would learn it quickly.
We learn our own language by hearing people speak it, not by seeing what they write. We imitate what we hear. In school, though you learn to read and write as well as to hear and speak, it is best to learn all the new words through the ear. You can read them, spell them, and write them later.

听力原文： Living things take from their environment and give back to their environment. In other words, living things and their environment are interdependent. Living things take matter and energy from the environment, and return matter and energy to the environment. For instance, animals feed on plants, or on other animals. And they return materials to the environment. This interaction goes on continually.
Man also is in active give-and-take relations with his environment. However, there is one way in which man is different. Other living things do not change their environment the way man does. Man is not only adapted to the environment. He alters his environment in other complex ways.
How is it that man can alter his environment, as no other living thing can？ It is because of his brain. With his brain, man learns.
Man's brain makes it possible for him to record what he learns. He puts his records in words, in pictures, in sounds. In this way man can pass on what he learns to other men.
