阐述二语对母语影响研究的发展过程、总体评价以及整体趋势。该领域的研究可分为三个阶段,即发现、确立和兴起以及深化拓展时期。现有研究多探讨中学生或成人的双语研究,针对儿童的研究非常薄弱,且仅有的儿童语言研究多关注母语的读写能力。该领域的研究趋势是加强儿童习得研究;研究对象扩展为母语整体语言体系及其使用认知。 Explain the development of second language research on the impact of mother tongue, the overall evaluation and the overall trend. Research in this area can be divided into three phases, namely discovery, establishment and rise, as well as deepening the expansion period. The existing studies mainly explore bilingual studies of middle school students or adults, the research on children is very weak, and the only studies on children’s language focus more on the reading and writing ability of native speakers. The research trend in this field is to strengthen the study of children’s acquisition; the research object is extended to the overall language system of mother tongue and its cognitive use.
