“有”字句是聋生书面语教学中的重要句式。中国聋生习得汉语“有”字句偏误数量较多，大体可分为不应使用而误用“有”字句、应当使用“有”字句却产生误用两种类型，偏误原因主要有手语干扰、已学汉语知识的负迁移、学习策略及教学策略的不当等几个方面。针对不同成因的偏误采取不同的教学策略，是提高聋生汉语“有”字句教学效率的有效途径。

 How to use "You" sentences is an important part of deaf students' written language teaching. Deaf students have more errors of "You" sentences in the Chinese acquisition, which are generally classified into two kinds: "You" should not be used but misused, and "You" should be used but misused. We come to a conclusion that the deaf students' errors of "You" sentences are mainly due to the interference of sign language and also originate from the overgeneralization of the Chinese language and improper learning and teaching strategies. The effective way is to use different teaching strategies according to different errors in order to improve the second language teaching efficiency.
