This paper is an attempt to analyse the role of negative transfer in the acquisition of business English correspondence through the analysis of errors made in learners’writings.The analysis is focused on errors made violating clarity.Through the contrast between those errors and the normative samples,one of the deep-rooted reasons that prohibits learners to make the correspondences be clarified are discovered,which is the negative transfer resulted from different thought patterns affected by the cultural diversities. 展开更多

Writing is an integrated task which can test language learners’ability towards vocabulary,grammar,syntax,etc,and is therefore favored by many examinations both at home and abroad.However,Chinese students tend to perform poorly in English writing.The paper randomly chooses 30 compositions from sophomores from a Beijing university and picks out the syntactic errors,which can hardly be corrected merely by reference books and is therefore of great value.These errors are classified into eight types and the reasons are put forward in order for students to avoid them in future studies. 展开更多

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

There commonly exists a phenomenon of negative transfer of Chinese in our students' English writing. 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

Based on the researches of language transfer,contrastive analysis and error analysis,this paper tries to investigate the negative transfer of Chinese on Chinese students'English writings from the perspective of syntax.During one and a half months'teaching practice in Shannxi Hanzhong No.1 Middle School,the author lived through the real teaching process and found that there were lots of problems in students'English writings.The author makes a contrastive study of the different characteristics existing in Chinese and English languag es at the level of syntax,and analyses the typical syntactic errors appearing in the 60 students'English compositions collected from one or dinary class.These syntactic errors are caused by the negative transfer of Chinese.The purpose of the investigation is to study in what pat tern students have been influenced by Chinese in their English writings.Based on the findings and analysis of the mother tongue transfer on English writings,some implications are also provided in order to help minimize or eliminate the interference of negative transfer of the Chinese in students'English writings and improve the teaching and learning of English. 展开更多

In field of Second Language Acquisition, mother tongue has both positive transfer and negative transfer. Using proper foreign language learning strategies can effectively avoid the negative transfer of mother tongue and improve learners' oral English competence. Based on the theories of language transfer, this thesis mainly focuses on, error analysis and inter-language theory. In recent years, more and more scholars have studied the transfer of mother tongue in the field of College English teaching, and the points are also different. However, there is little research on the influence of mother tongue transfer in non English majors' spoken English. This case study chooses a non-English major student as the research object, and analyzes the causes of errors and linguistic categories in spoken English. The motivation of this student for learning spoken English is to attend graduate oral interview and TOEFL. This subject were asked to attend two oral tests and an interview. Through the anglicizing and investigating of the experimental data, the author finds that the errors in spoken English by the student are mainly affected by the negative transfer and negative cultural transfer of mother tongue. The errors of spoken language transfer are mainly reflected in phonetics, vocabulary, syntax and pragmatics. This thesis will focus on three aspects: vocabulary, syntax and pragmatics. The research results also show that the most difficult problem for non English majors in the course of spoken English is the lack of vocabulary. And so it is difficult to express their ideas in English. 展开更多

Computation of error in estimation of nonlinearity in ADC using histogram test are reported in this paper. Error determination in estimation of Differential Nonlinearity (DNL) and Integral Nonlinearity (INL) of an ADC is done by taking deviation of estimated value from actual value. Error in estimated INL and DNL is determined to check the usefulness of basic histogram test algorithm. Arbitrary error is introduced in ideal simulated ADC transfer characteristics and full scale simulated sine wave is applied to ADC for computation of error in estimation of transition levels and nonlinearity. Simulation results for 5 and 8 bit ADC are pre-sented which show effectiveness of the proposed method. 展开更多
