蒸汽印刷廠相關
At the same time, operators of the first printing presses run by steam rather than by hand found it possible to produce a thousand pages in an hour rather thanthirty. (31, TPO6)
參考翻譯：
同時，第一批通過蒸汽執行而不是通過手動的蒸汽印刷廠的操作者們發現在一個小時內生產一千張紙是有肯能的，而不需要三十小時。
這個句子的主要修飾成分就是介詞和非謂語動詞。
At the same time, operators of the first printing presses (run by steam) rather than (by hand) found it possible (to produce a thousand pages in an hour rather than thirty.)
分析：
修飾一：(run by steam) ，非謂語動詞，修飾printing presses，大家注意這裡的run不是謂語動詞，而是後面的found，這裡易混
中文：通過蒸汽執行
修飾二：(by hand)，介詞短語，修飾printing presses，注意rather than，超級高頻短語，之前也碰到過了，它是一個介詞，“而不是”
中文：而不是通過手

大氣引擎相關
This “atmospheric engine,” invented by Thomas Savery and vastly improved by his partner, Thomas Newcomen, embodied revolutionary principles, but it was so slow and wasteful of fuel that it could not be employed outside the coal mines for which it had been designed. (43, TPO6)

參考翻譯：
這個由Thomas Savery發明並由他的搭檔Thomas Newcomen大力改善的“大氣引擎”體現了革命性的原理，但它如此慢和浪費燃料以致於不能再煤礦的以外的地方使用，儘管原來是這麼設計的。
這個句子的主要修飾成分就是從句和插入語。
This “atmospheric engine,” (invented by Thomas Savery and vastly improved by his partner, Thomas Newcomen,) embodied revolutionary principles, but it was so slow and wasteful of fuel (that it could not be employed outside the coal mines) (for which it had been designed.) (43, TPO6)
分析：
修飾一：(invented by Thomas Savery and vastly improved by his partner, Thomas Newcomen,) ，插入語，修飾this “atmospheric engine”，大家注意這裡的斷句，This “atmospheric engine” embodied revolutionary principles被隔開了，斷句很重要
中文：由Thomas Savery發明並由他的搭檔Thomas Newcomen大力改善的
