中文摘要：

通过分析语体差异大的同义词，可以了解语体之间的差异。本文采用定量分析的方法，计算出1343对具有显著口语、书面语语体差异的同义词。通过对这些词对的调查分析可知：词性上，语体差别最大的同义词中动词最多；重叠、词缀、古汉语遗留词汇在同义词中所占的比重都较小；若一对同义词有音节上的差异，则口语倾向于为单音节，书面语倾向于为双音节。本文的调查结果对语言教学以及教材编写都有一定的启示。

英文摘要：

By analyzing the differences in synonyms,we can understand the stylistic differences. In this paper,certain algorithms are used to calculate 1343 pairs of synonyms which show significant stylistic differences. From quantitative analysis on these pairs,we conclude that： most words in the pairs are verbs; overlapping, affixes, ancient Chinese words are small in proportion;if one pair of synonyms have different syllables,the spoken word tends to be monosyllabic and the written word disyllabic. These conclusions can provide some in- spiration for language teaching.
