中文摘要：

2＋1式复合词在整体上表现出很强的名词属性,进入其中心语位置的成分即使原本不是名词,也表现出名词性。兼类词在2＋1式复合词中心语位置出现时,就会选择名词属性。2＋1式复合词或名词性复合词,倾向于在有选择余地时选择指称性强的形式作为其组成成分,在没有选择时,一般用为陈述性的成分,也有可能成为复合词的组成成分。本文还从历时的角度解释了动宾结构在充当复合词中的修饰性成分时的不同语序。

英文摘要：

Trisyllbic compounds with the internal structure of 2 ＋ 1 （i. e. two syllables plus one syllable） exhibit a strong tendency to be nominal. Words that can enter the head po- sition of this kind of trisyllabic compounds demonstrate nominal properties even though they are verbs or adjectives when used independently. Some words that can have two syn- tactic categories will be selected the nominal one when appear on the head position of trisyllabie compounds. The components on the non-head position of trisyllbic compounds are tend to be referential when it is possible. Those elements that are predictive can be cho- sen as a modifying component of trisyllabic compounds when there is no other choice. The different word orders involving VO structures as the non-head part of compounds are ex- plained from a diachronic perspective.
