词汇知识广度和深度对二语阅读理解贡献力比较研究

通过分析60名英语学习者的一些数据可比较词汇知识广度和深度对二语阅读理解的贡献力。多元回归分析表明，词汇知识广度和深度对二语阅读理解有较强的同等预测力。在词汇知识广度层面，接受性和产出性词汇量对二语阅读理解的贡献力几乎相同，但是在词汇知识深度层面，聚合知识的贡献力则明显大于一词多义知识。二语教学中对词汇知识的各个成分均应给予重视，尤其要重视一词多义知识等二语学习者掌握薄弱的成分。

Relative Contributions of Breadth and Depth of Vocabulary Knowledge to L2 Reading Comprehension

This paper compares the contributions of breadth and depth of vocabulary knowledge to L2 reading comprehension by analyzing the data from 60 English learners. As a multiple regression analysis indicates, both the breadth and depth of vo cabulary knowledge make equally strong contributions to L2 reading comprehension. Within the breadth of vocabulary knowl- edge, receptive and productive vocabulary sizes make similar contributions to 1.2 reading comprehension, white within the depth of vocabulary knowledge, paradigmatic knowledge contributes much more than polysemous knowledge. Therefore, L2 teaching should give weight to each component of vocabulary knowledge, even more weight to components like polysemous knowledge that L2 learners fail to acquire well.
