“过分”和“过于”是现代汉语中两个用法比较接近的超量程度副词。本文在大规模语料调查的基础上,运用统计和对比分析的方法对两者在表义倾向、句法分布及表达功能等方面的异同进行了描写和分析。 “Excessive ” and “Excess ” are more approximate adverbs of excess in modern Chinese. On the basis of large-scale corpus investigation, this paper describes and analyzes the similarities and differences between the two in terms of the sense of tenses, the distribution of sentences and the function of expression by means of statistics and comparative analysis.
