Abstract
Chinese temporal terms can be classified into nominal and adverbial categories. Since both share the main function, i.e. a modifier of a predicate or a clause, so it is an important issue to distinguish temporal nominals from adverbial ones from the viewpoint of second language acquisition. In the paper, we take ”一會兒yi-hui-er” for example to show that it could help teachers to teach and students to learn the composite morphemes of Chinese temporal nominals, analyzing the morphological construction and syntactic characteristics of different senses or syntactic distribution of a temporal nominal.
