摘　　要：该研究以型式语法为理论基础,通过链语法形式化语法体系对动词型式进行了形式化,并对链语法动词词典进行了重构,旨在构建一个更好的面向中国学生的英语书面语动词形式错误检查系统。测试结果显示,重构后链语法词典的查错性能和句法分析能力得到提高。对错句检查的召回率比原词典提高了4.5%,准确率提高了15.7%;对本族者正确分析句子的准确率提高了12.2%。研究表明,该研究所基于的语言学理论(动词型式语法)和形式模型(链语法)可以较好地适用于中国学生书面英语动词形式错误检查系统的构建。This study takes Pattern Grammar as the theoretical basis,among which verb patterns are formalized by a grammar formalism — ＂Link Grammar＂,to reconstruct the link grammar verb dictionary,aiming to build a better verb form error detection system for Chinese EFL learners＇written English.The test result shows that the verb form error detection capability and parsing performance of the extended link grammar dictionary are improved.The recall rate of verb form error detection by the reconstructed dictionary shows an increase of 4.5 %than the original and the accuracy rate 15.7%higher.Besides,link grammar with the reconstructed dictionary can parse correct sentences 12.2% higher than the original.The study shows that the linguistic theory（Pattern Grammar）and grammar formalism（Link Grammar）adopted in this study can be satisfactorily applied to the building of verb form error detection system for Chinese EFL learners＇written English.
