本文參照黃伯榮·廖序東和張斌的關于兼語句的理論, 把“S1+V1+S2+V2”結構分爲“使役”、“言說”、“喜怒”、“稱呼”及“有无”等5種類型。 “使役”類的“S2”，在基礎詞匯層次，卽VP層面上是謂語動詞的施事者；在BECOME事件意義層次上，從輕動詞BECOME獲得當事題元角色，据我們的分析，因爲謂語動詞的補足語不是“S2”，而是整個vP2, 因此“S2”不能從“V₁”獲得受事題元角色，而從“vP2(BECOME)”獲得當事題元。由此可以斷定“使役”類“S1+V1+S2+V2”結構不是所謂的兼語句。 其余4種結構的“S₂”均在CP層次上從輕動詞獲得相對應的題元角色:言說”類的“S2”在CP層次從輕動詞DO獲得施事題元角色；“喜怒”類的“S2”在CP層次從輕動詞BE獲得感事題元角色；“稱呼”類的“S2”在CP層次從輕動詞BE獲得系事題元角色；“有无”了的“S2”在CP層次從輕動詞都獲得施事題元角色。總之，“S2”不是“V1”的補足語，“S2+V2”構成CP相面，這個CP相面才是“V1”的補足語，因此“S2”无法從“V1”獲得受事題元角色，因此，可以斷定所謂兼語句幷非兼語句。
In this paper, we analyzed the “S1+V1+S2+V2” structure into five types: directive, discourse, emotion, appellation, and presence-absence. In doing so we referred to the theory of Borong Huang, Xudong Liao and Bin Zhang on pivotal sentences. In the directive type, “S2” is the basic vocabulary, the Agent of Predicative Verbs in VP level, gets the thematic role of Experiencer from the light verb BECOME in the eventual stage. According to the analysis of the text, Complement of Predicative Verbs is vP2 in total not “S2”. Therefore, “S2” does not get the role of Patient from “V1”, but vP2 in total gets the thematic role of Experiencer. So, the directive type`s “S1+V1+ S2+V2” structure can not be stated as pivotal in the literal sense. The other four types of structure of “S2” gets the role from CP to light verb. In the discourse type, “S2” gets the thematic role from CP to light verb DO, in emotion type, “S2” it gets the Sentient thematic role from CP to light verb BE, in appellation type, “S2” gets Relevant thematic role from CP to light verb BE, and in the presence-absence type, “S2” gets the Agent thematic role from CP to light DO. Based on the analysis, “S2” is not a complement of “V1”, it is the complement of the Phase made up of “S2+V2”. Therefore, “S2” can not get the Patient thematic role from “V1”, and can not be stated as pivotal in literal sense.
