丁香园AV

丁香园AV is a local site for the  (NACLO). NACLO is a fun and educational contest for U.S. and Canadian high-school students in which contestants compete to solve compelling and creative puzzles in linguistics and computational linguistics. Requiring no previous knowledge of linguistics, languages, or computing, the puzzles can be solved by analytic reasoning alone, and serve as a stimulating introduction to the field of linguistics. In solving the problems, students learn about the richness, diversity and systematicity of language, while exercising natural logic and reasoning skills.

Students from high schools across North America compete in the Open Round. Top students from the Open Round travel to the Invitational Round. Winners of the Invitational have a chance to represent their country (USA or Canada) at the International Linguistics Olympiad.
