第二语言的词汇习得研究越来越引起人们的关注。而人们对词汇的研究大多限于对词汇广度或词汇量的研究,近十几年来,国内外研究学者开始把重点转移到对词汇的深度的研究。而国内相关研究虽相对较晚但成果显著。本文回顾分析了国内外词汇深度研究的现状并就该领域的进一步发展提出了建议。 Vocabulary acquisition of second language is attracting more and more attention. However, most people’s research on vocabulary is limited to the study of vocabulary breadth or vocabulary. In recent ten years, researchers at home and abroad have begun to shift their focus to the study of the depth of vocabulary. However, although the relative domestic research is relatively late, the result is remarkable. This paper reviews the current status of the research on lexical depth at home and abroad and gives some suggestions on the further development of the field.
