本文以汉字笔画“竖弯钩”为例,通过对外国留学生易错字例进行归类分析,发现留学生在汉字书写中存在的一些类型化的偏误,利用字源分析可以更加有效地帮助留学生理解偏误产生的原因,并且自觉地避免同类偏误的产生,从而提高汉字学习效率。 This paper takes the Chinese character strokes “vertical hook ” as an example, through the classification analysis of the foreign students’ mistakes and omissions, and finds that there are some typological errors in the writing of Chinese characters by foreign students. Using etymological analysis can help foreign students Understand the causes of errors, and consciously avoid the generation of similar errors, thereby improving the efficiency of Chinese learning.
