句法结构歧义主要由句子的结构层次、结构关系、语义指向、语义特征、语义关系、语义焦点等不同所带来,不同的原因形成的歧义,理解时加工的方式会不同。歧义理解的加工方式常用的有“组块法”、“指向法”、“转换法”和“投射法”。不同语言能力的人对这些方法的掌握情况存在差异,从而形成了句法歧义理解上的差异。 Syntactic structure ambiguity is mainly caused by the differences in structure level, structural relationship, semantic orientation, semantic features, semantic relations, and semantic focus of sentences, and different ways of processing ambiguities and understandings. Ambiguous understanding of the processing methods commonly used are “block method”, “point method”, “conversion method” and “projection method.” Differences in mastery of these methods were found among people of different linguistic abilities, which led to differences in comprehension of syntactic ambiguity.
