中文摘要：

聋生书面语语法知识习得及习得过程是影响特殊教育教学效果和效率的关键因素之一。基于语料库的聋生书面写作研究在我国还为数不多。本文对十万字左右的聋生日记进行了研究，目的在于发现聋生写作中否定结构习得过程的规律。研究结果表明：聋生的“不”和“没（有）”否定结构的习得过程是有序的。这种有序性反映了“不”和“没（有）”否定结构的复杂程度，而变化则体现在习得过程中所具有的消长性。

The results show that the deaf students follow a certain sequence in their acquisition of negative sentence structures, which reflects the complexity of the negative sentence structures, and that their acquisition of negative sentence structures demonstrates fluctuation.
