The basis for classifying phrases

三词组的分类
The basis for classifying phrases
我们可以从以下几个方面来区别不同词组的特点:
We distinguish the various phrases according to the following features :

1.词组是由什么词类充当的,以及表达什么样的语法关系和意义。
In terms of the parts of speech, grammatical relations and meanings of their constituents.

词组内部的词序是否固定。
In terms of whether their constituents are arranged in a fixed order.
词和词之间用不用虚词以及用什么虚词连接。
In terms of the ways in which their constituents are connected, ie. whether conjunctions are employed and if so what kind of conjunctions are employed.
4.词组前后能否带其他成分以及能带什么样的成分。
In terms of whether the phrase can be preceded or followed by other elements and of what kind these elements are.
