but opponents of change among the regulators insist that keeping outsiders out of a law firm isolates lawyers from the pressure to make money rather than serve clients ethically.
问题: 有一位老师说 “句子的最后一处存在省略,如果还原的话,就是这个样子:...rather than pressure to serve clients ethically,也就是这样做的话律师就不存在(rather than)道德压力了(pressure to serve clients ethically)。换句话说律师就会有道德底线了。千万不要以为否定词rather than否定的是serve client ethically(那样的话,serve应该变成动名词serving)。” 请问为什么serve 应该变为动名词?
