英语语言习得研究表明,英语词汇可分为认识型词汇、活用性词汇、核心词汇,对认知型词汇的认识反映词汇习得的“量”,对活用性词汇的掌握反映词汇习得的“质”。目前我国大学英语教学词汇习得“质”的方面还存在较多问题,在强调扩大“量”的同时,决不能忽视“质”的标准,应加强研究,提高大学生词汇习得的量与质。 English language acquisition research shows that English vocabulary can be divided into cognitive vocabulary, active vocabulary, core vocabulary, cognition of cognitive vocabulary reflects the “amount” of vocabulary acquisition, mastery of active vocabulary reflects the vocabulary acquisition “quality”. At present, there are still many problems in the acquisition of “quality” in college English vocabulary teaching. While emphasizing the expansion of “quantity”, we must not neglect the standard of “quality”. We should strengthen research and improve the quality and quantity of college students’ vocabulary acquisition .
