     What has the telephone done to us or for us in the hundred years of its existence? A few effects suggest

themselves at once. It has saved lives by getting rapid word of illness, injury, or fire from distant places. By

joining with the lift to make possible the multi-story building or office building, it has made possible-for better

or worse-the modem city. By bringing about a great leap in the speed and ease with which information moves

from place to place, it has greatly sped up the rate of scientific and technological changes and growth in

industry. Beyond doubt it has seriously weakened, if not killed, the ancient art of letter writing It has made living

alone possible for persons with normal desires; by so doing, it has played a mile in one of the greatest social

changes of this century, the breakup of the multi generational house-hold. It has made the war more efficient

than before. Perhaps though not provably (可证实), it has prevented wars that might have arisen out of

international misunderstanding caused by written communication. Or perhaps-again not probably-by

magnifying and extending irrational (非理性的) personal disagreement based on voice contact, it has caused

wars. Certainly it has extended the scope (范围) of human conflicts, since it fairly spreads the useful knowledge

of scientists and the nonsense of the ignorant (无知者), the affection of the affectionate and the malice (恶意)

of the malicious.
