本研究旨在探讨词汇知识的两个维度--词汇知识的深度和广度对预测最小词汇量为3000个词族的EFL学习者的阅读成绩的贡献程度，以及词汇知识深度和广度高、低两组学生的阅读理解成绩之间的差异。所有工具（测量词汇知识深度（DVK）的单词联想测试（WAT）（Read，1993））、测量词汇量（VS）的词汇水平测试（VLT）（Nation，1983）和阅读理解测试（RC））在同一次会议上对38名伊朗高年级大学生进行了测试。然后通过Pearson相关和两个独立T检验对收集的数据进行分析。结果表明：（1）词汇深度、词汇量和词汇量之间存在高度正相关;（B）词汇深度知识对阅读理解有显著的预测作用;（3）词汇深度和广度知识越丰富的学生，其阅读理解成绩越好。这些发现为词汇深度知识在阅读理解中的重要性提供了实证支持。鉴于此，将这方面纳入EFL课程和活动的必要性是可取的。
This study was conducted to investigate the extent to which scores on depth and breadth of vocabulary knowledge as two dimensions of vocabulary knowledge would contribute to predicting the EFL learners' reading performance with a minimum vocabulary size of 3000 word families and also to find out the difference, if any, between the reading comprehension performance of two groups as having high and low depth and breadth of vocabulary knowledge. All instruments (Word-Associate Test (WAT) (Read, 1993) measuring depth of vocabulary knowledge (DVK), Vocabulary Levels Test (VLT) (Nation, 1983) measuring vocabulary size (VS), and Reading Comprehension Test (RC) were administered together within the same session to 38 Iranian senior university students. Then the gathered data were analyzed by a Pearson correlation and two Independent T-tests. Results revealed that a) the interrelations among DVK, VS, and RC were high and positive; b) depth of vocabulary knowledge provided a significant contribution to the prediction of reading comprehension; and c) the students who had stronger depth and breadth of vocabulary knowledge performed better on reading comprehension. These findings provided empirical support for the importance of depth of vocabulary knowledge in reading comprehension. Regarding this, the necessity of incorporating this aspect into EFL programs and activities is desirable.
