由于较多的日语学习者在使用日语交流时,把一些日语的近义表达等同使用,从而造成所表达出来的语义和自己想表达的内容不相符合。为了学习者对日语的近义表达能有更好的认识和正确的区分,本文以[～ぅちに、～前に]为例子,对日语的这种近义表达的差异作出明确的分析。 As more Japanese learners use Japanese in their conversations, some Japanese equivalents are used in a similar way, resulting in inconsistent semantics and content they want to express. In order to have a better understanding and correct distinction of learners’ near-synonymous expressions in Japanese, this paper makes a clear analysis of the differences in this kind of near-synonymous expression in Japanese by taking the example [~ ぅ ち に, ~ 前 に] as an example.
