CET4成绩受很多因素影响,具有灰色系统的属性,可以利用灰色理论对其进行预测,进而对其进行分析。以2003～2006级本科二年级学生CET4成绩数据为基础,利用灰色理论对成绩进行预测并分析了各项成绩变化特征。结果表明:平均总分及各单项平均成绩都较低,但都呈上升趋势。根据预测和分析结果,对CET4及其结果进行讨论,为大学英语教学提供参考。 CET4 grades are influenced by many factors, with gray-system attributes that can be predicted using gray theory and then analyzed. Based on the CET4 scores of sophomores from 2003 to 2006, the author uses the gray theory to predict the grades and analyzes the characteristics of the scores. The result shows that the average total scores and the individual average scores are lower, but all show an upward trend. Based on the prediction and analysis results, CET4 and its results are discussed to provide reference for college English teaching.
