中动结构隐含的施事必须具有自主能力,评价性成分经由动词动作指向受事主语,表示受事具有接受动词动作影响的属性,类似于“可/能V的”或者“V-able”。中动结构的概念内容和相应的施动句一样,只是突显的焦点不同。施动句突显的是施事和受事,分别是注意的主焦点和次焦点。中动结构突显的是已发生状态变化的受事。施事退隐是施事被排除在注意范围之外、受事成为主焦点的结果。中动结构的语义内容是其概念内容从“有界”“异质”变为“无界”“同质”的结果。 The implicit affirmative action must have autonomous ability, and the evaluation component points to the subject via the verb action, indicating that the affair has the property of accepting the verb action similar to “V / v ” or “V -able ”. The concept of the dynamic structure and the corresponding actuator sentence, just highlight the different focus. Execution sentence highlights the things and events, respectively, the main focus and sub-focus of attention. The dynamic structure highlights the events that have taken place. Retirement is the event was excluded from the attention of the scope of the incident as the main focus of the results. The semantic content of the middle moving structure is the result of the concept content changing from “bounded ” “heterogeneous ” to “unbounded ” “homogeneous”.
