As it is known, both English and Chinese Adjectives mainly function to modify a nominal head. As for their marked and unmarked constructions, it reveals that an attributive adjective simply precedes a head noun without any overt markers. With the semantic features of adjective, especially of the complexity of adjective phrases, however, both Chinese and English have to take some ways to mark the adjectival attributives. In general, Chinese marks those adjectival attributives by use of the constructional particle ‘de’, and English marks them by means of different word orders. Both quantification and complexity of construction constitute the major motivations for their markedness. The present research is helpful for a better understanding of the grammars of the two languages and also significant for second language learning or teaching.
