现代研究方式证明,结构较为稳定、语义较为完整的词块是语言学习中有效的语言单位。国内学者研究认为英语词汇教学的一个重点必须放在常用词块教学上,因为是否掌握本族语者常用的词块直接关系到学习者语言的准确性和地道性,该结论也适用于日语的词汇教学。本文参照英语中的词块分类方法,对于日语的词块进行了分类,并指出合理利用电子词典能极大提高对于词块的掌握程度。教师需要在课堂上提出日语词块的概念,再加上具体指导让学习者对词块变得敏感起来,最终达到学生利用电子词典自主学习日语词块的目的。 Modern research methods prove that the structure is relatively stable, the more complete semantic block is the language unit of effective language learning. Domestic scholars believe that one of the focuses of English vocabulary teaching must be placed on common vocabulary teaching because whether or not to grasp the commonly used words in native speakers is directly related to the accuracy and authenticity of the learner’s language. This conclusion also applies to Japanese Vocabulary teaching. In this paper, we classify the Japanese lexical chunks according to the lexical chunk classification method in English, and point out that the rational use of electronic lexicon can greatly improve the mastery degree of lexical chunks. Teachers need to put forward the concept of Japanese word block in the classroom, and with specific guidance to make learners become sensitive to the word block, and ultimately achieve the purpose of students to learn Japanese word blocks by using the electronic dictionary.
