“又”和“再”是汉语口语和书面语都常用的两个副词。由于意思相近,初学汉语的留学生在语言实践中经常用错。本文通过大量例句,对学生的错误进行了分类,从语义、语法、用法等方面区别二者,并提出相应的教学策略。 “Again ” and “Again ” are two adverbs commonly used in spoken Chinese and written Chinese. Due to the similarities and differences, beginners Chinese students often use the wrong language practice. In this paper, a large number of examples are used to classify students’ mistakes and distinguish the two from semantics, grammar and usage, and put forward corresponding teaching strategies.
