　　Passage 1

　　如果你從未見過一座發(fā)電廠，你可能很難想象發(fā)電設(shè)備是多么復(fù)雜，鍋爐能產(chǎn)生多么巨大的熱量，而爐子每天又是需要燒多少煤。

　　舉例說，我們的一座發(fā)電廠——摩根頓發(fā)電廠——的各臺(tái)鍋爐一天中就能把二千四百萬加侖的水化為蒸汽。這座電廠的爐子一天之內(nèi)就消耗九千九百噸煤。波多馬克電力公司(PEPCO)用煤量如此巨大，以致我們專門購置了兩列八十節(jié)車皮的火車以加速輸送煤的過程。僅僅一座摩根頓電廠就能每天生產(chǎn)二千五百萬千瓦小時(shí)的電。

　　電是靠使大型磁鐵在發(fā)電機(jī)內(nèi)的線圈里面轉(zhuǎn)動(dòng)而產(chǎn)生的。磁鐵轉(zhuǎn)速愈高，產(chǎn)生的電壓就愈高。電流從波多馬克電力公司的發(fā)電機(jī)出來時(shí)，其電壓在13,800伏至24,000伏之間。

　　下一道程序是使電流通過一個(gè)變壓器，把電壓提升，并使電繼續(xù)向前進(jìn)。一根導(dǎo)線就象一根小口徑的水管。把電壓升高就象給水加壓一樣，這樣一來就會(huì)使這個(gè)系統(tǒng)中能量的運(yùn)動(dòng)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.
