【正确答案】Whatever people do when they come together—whether they play, quarrel, make friends, or make automobiles—they talk. We live in a world of language. We talk to our friends, our associates, our wives or husbands, our lovers, our teachers, our parents and in-laws, and we also talk to bus drivers and total strangers. We talk face to face and over the telephone, and everyone responds with more talk. Television and radio further encourage this torrent of words. Hardly a moment of our waking life is free from words, and even in our dreams we talk and are talked to. We also talk when there is no one to answer. Some of us talk aloud in our sleep. We talk to our pets and sometimes to ourselves. The possession of language, perhaps more than any other attribute, distinguishes humans from other animals. To understand our humanity, one must understand the nature of language that makes us human. According to the philosophy expressed in the myths and religions of many peoples, it is language that is the source of human life and power. To some people of Africa, a newborn child is a "thing," not yet a "person." Only by learning does the child become a human being. Thus, according to this tradition, we all become "human" because we all know at least one language.
