复杂长句翻译实例 The method of scientific investigation is nothing but the expression of the necessary mode of working of the human mind; it is simply the mode by which all phenomena are reasoned about and given precise and exact explanation. 科学研究的方法不过是人类思维活动的必要表达方式，也就是对一切现象进行思索并给以精确而严谨解释的表达方式。 There is no more difference，but there is just the same kind of difference，between the mental operations of a man of science and those of an ordinary person，as there is between the operations and methods of a baker or of a butcher weighing out his goods in common scales，and the operations of a chemist in performing a difficult and complex analysis by means of his balance and finely graded weights. 科学家的思维活动与普通人的思维活动之间的区别和面包商或卖肉者用普通磅秤称货的操作方法与化学家在进行艰难而复杂的分析时用天平和精密刻度的砝码的操作方法之间的区别是完全相同的，此外就没有别的区别了。 　 It is not that the scales in the one case，and the balance in the other，differ in the principles of their construction or manner of working; but that the latter is much finer apparatus and of course much more accurate in its measurement than the former. 这并不是说面包师或卖肉者所用的磅秤和化学家所用的天平在构造原理和工作方式上存在差别，而是说与前者相比，后者是一种更精密得多的装置，因而在计量上必然更准确得多。 You will understand this better，perhaps，if I give you some familiar examples. 要是我给你举几个熟悉的例子，或许你会更清楚地理解这一点。 You have all heard it repeated that men of science work by means of induction（归纳法）and deduction，that by the help of these operations，they，in a sort of sense，manage to extract from Nature certain natural laws，and that out of these，by some special skill of their own，they build up their theories. 你们多次听说过，科学家是用归纳法和演绎法工作的，他们用这些方法，在某种意义上说，力求从自然界找出某些自然规律，然后他们根据这些规律，用自己的某种非同一般的本领，建立起他们的理论。 And it is imagined by many that the operations of the common mind can be by no means compared with these processes，and that they have to be acquired by a sort of special training. 许多人以为，普通人的思维活动根本无法与科学家的思维过程相比，认为这些思维过程必须经过某种专门训练才能掌握。 To hear all these large words，you would think that the mind of a man of science must be constituted differently from that of his fellow men; but if
