　　Passage 1

　　如果你从未见过一座发电厂，你可能很难想象发电设备是多么复杂，锅炉能产生多么巨大的热量，而炉子每天又是需要烧多少煤。

　　举例说，我们的一座发电厂——摩根顿发电厂——的各台锅炉一天中就能把二千四百万加仑的水化为蒸汽。这座电厂的炉子一天之内就消耗九千九百吨煤。波多马克电力公司(PEPCO)用煤量如此巨大，以致我们专门购置了两列八十节车皮的火车以加速输送煤的过程。仅仅一座摩根顿电厂就能每天生产二千五百万千瓦小时的电。

　　电是靠使大型磁铁在发电机内的线圈里面转动而产生的。磁铁转速愈高，产生的电压就愈高。电流从波多马克电力公司的发电机出来时，其电压在13,800伏至24,000伏之间。

　　下一道程序是使电流通过一个变压器，把电压提升，并使电继续向前进。一根导线就象一根小口径的水管。把电压升高就象给水加压一样，这样一来就会使这个系统中能量的运动加快。

　　On the Cultivation of the Imagination

　　I address these words in favor of the cultivation of the imagination.

　　In what sense, then, do I use th6 word "imagination"? The meaning of "imagination" is "the power of forming ideal pictures"; "the power of representing absent things to ourselves and to others." That is the sense in which I shall use the word "imagination" in the course of my address.

　　Now follow out this thought and I think I can make my meaning clear. Absent things! Take history. History deals with the things of the past. They are absent in a sense, from your minds — that is to say you cannot see them; but the study of history qualifies you and strengthens your capacity for understanding things that are not present to you, and thus I wish to recommend history to you as a most desirable course of study.
