【答案解析】[听力原文]
Professor Smith is explaining to his student, Ann, why it"s improper to call a computer an, "electronic brain".
Professor: I"m afraid, Ann, you"re not very accurate when you call a computer an "electronic brain."
Ann: Oh? But professor, you see, most people do.
Professor: Yes, it was given that title by some misguided journalists not long after the first modem electronic computer was built in 1946.
Ann: It"s electronic, professor, so you must be objecting to the word "brain"?
Professor: Exactly, Ann. There are similarities with the human brain, but there is one very important difference.
Ann: You mean the computer is better?
Professor: In some way, yes; but not in something that is quite fundamental.
Ann: Let me think. Do you mean the fact that the machine is controlled by man?
Professor: Full marks. You see, despite all its accomplishments, the so-called electronic brain must be programmed by a human brain.
Ann: Programmed? What do you mean?
Professor: A program is a sequence of instructions prepared for the computer, enabling the computer to solve a given program. The point is that a human tells the machine what to do, when to do and how it is done.
Ann: I see. Do you program information for the computer"s memory?
Professor: Yes, except that the word memory has rather gone out of fashion. The computer doesn"t really remember. Information is stored in it. Well, let"s go to the computer room and I"ll show you how a computer works.
Ann: OK, it"s very kind of you.
