In the C —E translation of instructions of goods,transfer occurs as well. It is necessary to give a through study into those negative transfers in the instructions to improve the quality of translation. This paper takes the English instructions of electronic appliance in the New Century Supermarket in N anchang University as the subjects. Through a qualitative and a quantitative study of the subjects, the author concludes that negative transfer can be found here and there in the English instructions-negative transfer at lexical level, syntactical level and discourse level, negative transfer at syntactical level having the highest frequency. This paper also explores the reason why the phenomena occurs.展开更多

Grammar, vocabulary, and expression are marked by the interference of Chinese which greatly impedes the improvement of the students' writing communicative competence. This is mainly due to the inadequacy of the students' language input. In view of the present situation, this paper aims to analyze some typical errors that the senior school students (Grade l)make in their writing so as to reveal the tact that during the process of second language acquisition, learners tend to transfer some of their Ll features into the target language in the field of phonetic, vocabulary, especially in the field of grammar. Therefore. the study of the Ll transfer and the error analysis are crucial in the research of the writing of a L2 and it plays an important role in the teaching and learning of a L2.展开更多
