Comments In this part，the training focus is on some sentence constructions as to increase．But when we translate these constructions，we ought to pay special attention to the different expressions in Chinese versions．In other words，the same original has two Chinese versions．Therefore，we ought to clearly understand the two different versions of the same English expression．In addition，apart from some words，phrases and constructions，we can reach a conclusion that the following sentence structures have the same meanings:
①A is N times bigger than B．
②A is bigger than B by N times．
③A is N times as big as B．
The exact meaning of the three structures is: A = B × N

②A is smaller than B by N times．
③A is N times as small as B．
That is to say，the meaning of the three structures is the same．But when we translate the multiple in decreasing，Chinese character translation is quite different from the multiple in increasing．This is because Chinese character倍is only used in increasing，not in decreasing although the word“times”is the same in both cases．
