In order to better serve the international Chinese teaching, according to the sentence-based syntactic system and Chinese syntax structure characteristics, the paper builds a basic sentence-pattern instance database based on the international Chinese textbook Treebank. Based on the instance database, the paper adds an index for the predicate, and then extracts the relevant knowledge and information of predicate keywords. Finally, a certain amount of complex natural language sentences are converted into more instances with teaching values, which provide basic resources for international Chinese teaching.
