After you hear a question, you must choose the best answer from the four choices marked A, B, C and D. 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 s 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. (27)
