本文讨论“的”用于已然动作的条件,并试图分化“的”与“了”的用法。“的”用于已然动作时,有其必须遵循的语法规则,即这个已然动作是发话人与听话人共知的。疑问句中发话人向听话人询问已然动作的时间、地点、方式等信息;陈述句中发话人向听话人传递已然动作的时间、地点、方式等信息。 This article discusses the use of “” for already-action conditions and attempts to differentiate between “” and “” for usage. “” Is used in the already action, there is a grammatical rule it must follow, that is, this already action is known to both the caller and the hearer. In the interrogative sentence, the caller asks the hearer for information such as the time, place, and method of the action already taken; the caller in the statement transmits the time, place, manner and the like of the already action to the hearer.
