羡余否定是汉语中的特殊语言现象，羡余否定结构是汉语中的特殊结构，也是汉语作为第二语言教学的难点。现代汉语中常见的羡余否定格式多达几十余种，因“差一点儿没+VP”格式又存在歧义现象，影响最广泛的“企望说”有存在局限性，所以第二语言学习者在学习“差一点儿没+VP”格式时更加难以把握，容易出现理解错误。因此，本文对前人的羡余否定研究成果进行总结，在总结的基础上对“差一点儿没+VP”格式所造成的歧义进行分析，以此总结出在对外汉语教学时的教学策略，以期进一步完善对外汉语教学体系。

Redundant negation is a special language phenomenon in Chinese. Redundant negation structure is a special structure in Chinese, and it is also a difficult point in teaching Chinese as a second language. There are dozens of forms of redundancy negation in modern Chinese. Because of the ambiguity of the "almost no +VP" format, the most widely influential "hope theory" has its limitations, so it is more difficult for second language learners to grasp the "almost no +VP" format, and it is prone to misunderstanding. Therefore, this paper summarizes the previous research results of redundancy negation, analyzes the ambiguity caused by the "almost no +VP" format, and summarizes the teaching strategies in teaching Chinese as a foreign language in order to further improve the teaching system of Chinese as a foreign language.
