日语作为粘着语所具有的一大特征,是其具有明显的格助词,以标志谓语与各名词间的关系。但是,在日常的口语表达中,这些体现与谓语关系的格助词却经常脱落,日语中被称为“ゼロ助詞”即“零助词”。在一般的日语教学中,很容易简单地将此助词脱落现象归为助词省略。但是,通过对比研究,发现这种现象具有独特的表达效果,需要引起日语教育者的高度重视。本篇主要探讨最普遍出现的主语及主题位置的零助词句的表达效果。 One of the major features of Japanese as a sticky language is that it has obvious lattice aids to mark the relationship between the predicate and the various nouns. However, in everyday spoken expressions, these auxiliaries, which express the relationship with the predicate, often fall off. In Japanese, they are referred to as “helping words” or “null auxiliary words”. In ordinary Japanese teaching, it is easy to simply classify this phenomenon of particle elimination as a particle omitted. However, through comparative studies, it was found that this phenomenon has a unique expression effect and needs to be highly valued by Japanese educators. This chapter focuses on the expression of zero-auxiliary sentences in the most commonly occurring subject and subject position.
