Lesson 42-2 Recording an earthquake

But instruments far more delicate than that were needed if any really serious advance was to be made. The ideal to be aimed at was to devise an instrument that could record with a pen on paper, the movements of the ground or of the table as the quake passed by. While I write my pen moves, but the paper keeps still. With practice, no doubt, I could in time learn to write by holding the pen still while the paper moved. That sounds a silly suggestion, but that was precisely the idea adopted in some of the early instruments (seismometers) for recording earthquake waves. But when table, penholder and paper are all moving, how is it possible to write legibly? The key to a solution of that problem lay in an everyday observation.

练习感悟：

9.13

今天是课文第二部分，比较短。要注意英美音区别，注意instrument中，t的浊化。注意suggestion作名词，有“联想，想象”的意思。词组in time有“最终，迟早”的意思。

简书到9.28才能恢复更新，这是后来补的。
