‘hǎohāor+de’ is composed of the syntactic superimposed form ‘hǎohāor’ and the structural auxiliary word ‘de.’ It is a structure that occurs very frequently in modern spoken Chinese. ‘hǎohāor’ can only act as an adverbial (have a good time) or an attribute (a quite good book in a sentence). ‘hǎohāor’ cannot be used alone, or act as a subject, an object or a predicate. Nor can it modify a noun or a noun phrase directly. However, ‘hǎohāor+de’ can be used alone, and can be used as a predicate, a complement, an attribute and an adverbial. Different syntactic functions of ‘hǎohāor+de’ have different semantic features. This is a difficult point for the students who are non-native speakers of Chinese. This paper discusses in detail the syntactic functions and the related semantic features of ‘hǎohāor+de,’ and also tries to probe into the source of it, hoping to provide some help for Chinese language teaching.
