词汇在语言学习过程中占有举足轻重的地位,但实证研究表明大多数学习者面临着外语词汇记忆难、遗忘快,心理词库匮乏、排列无序等主要障碍。针对这些问题,文章基于心理词库的相关理论探讨了一些有效的词汇习得策略,并进行了实证检验,旨在为二语学习者词汇能力的提高提供有益参考。 Vocabulary plays a decisive role in the process of language learning. However, empirical studies show that most learners are confronted with the major obstacles in foreign language vocabulary memory, fast forgetting, lack of mental lexicon, and disorderly arrangement. In order to solve these problems, this paper explores some effective vocabulary acquisition strategies based on the related theories of the thesaurus, and conducts empirical tests to provide useful references for improving the vocabulary ability of second language learners.
