It points out that their semantic functions are measured by the action or the time and the space of the central matters with action , and this structure is a method to indicate Chinese predicator number classifier feature , so it is declaration but not reference .
本文主要从语义功能的角度探讨一类二价动词句后面数量短语的句法属性,认为它们主要是对动作行为或者是以动作行为为中心的事件的时间性和空间性的计量,是表示汉语谓词性成分数量特征的一种手段,所以本质上是陈述的,而不是指称的,因此既可以充当补语也可以充当谓语,因其类别不同而导致陈述能力存在强弱之分,这制约其充当补语和谓语的能力。

But on this question one cannot speak generally, for it varies so much with the individual; I will only say this, that those men who at the commencement of a princedom have been hostile, if they are of a description to need assistance to support themselves, can always be gained over with the greatest ease, and they will be tightly held to serve the prince with fidelity, inasmuch as they know it to be very necessary for them to cancel by deeds the bad impression which he had formed of them; and thus the prince always extracts more profit from them than from those who, serving him in too much security, may neglect his affairs.
但是这种事情我们不能够概而言之,因为这件事情按照具体情况而异。我要说的只是,那些在一个国家肇始的时候是敌对的人们,如果他们是需要获得君主的支持以保持其地位的人们,新君主往往很容易赢得他们;而且由于他们明白自己必须用行动来消除君主原先形成的对他们的坏印象,他们更加不得不竭志尽忠侍奉君主。因此,君主从他们那里得到的利益,常常比从另一些人那里得来的多,因为后一种人抱着过分的安全感侍奉君主,从而对君主的事情掉以轻心。
