话语标记语on the other hand和on the contrary在英语中功能各异。前者主要有对比功能,后者有否定功能。通过语料库调查发现,中国学生普遍误认为后者有对比功能,因而在写作中将其误用为前者。造成这一现象的原因部分是由于词典的误导,但主要原因在于母语的干扰和无针对性的教与学。 Discourse markers on the other hand and on the contrary have different functions in English. The former has a contrast function, which has a negative function. Through corpus surveys, Chinese students generally mistakenly believe that the latter has a comparative function, so that they mistakenly use it as the former in writing. The reason for this phenomenon is partly due to the misleadingness of the dictionary, but mainly due to the interference of native language and the lack of targeted teaching and learning.
