改错题能从词汇、句子、语篇能力等多方面考查学生的语言水平。但多数英语教师对学生改错中出现的错误缺乏科学认识,导致同样的错误频繁出现,给英语教学带来了阻力。本文对所收集的501份有效样本进行了错误确认及分类,并找出其产生的原因,以期为英语教学提供指导。 Error correction questions can examine students’ language proficiency from a variety of aspects including vocabulary, sentence, and textual abilities. However, most English teachers lack scientific understanding of mistakes made by students in error correction, resulting in frequent occurrence of the same mistakes, which has brought resistance to English teaching. This article erroneously identifies and classifies the 501 valid samples collected, and finds out the reasons for this, in order to provide guidance for English teaching.
