A learner of any language as Second Language (SL), for example English, Arabic, Chinese, or German, enters an early, natural, and inevitable stage of making various errors in writing compositions. The errors could be due to dissimilar linguistic systems of the two languages (L1 and L2) or the lack of understanding the SL linguistic rules. This study focuses on investigating the frequent and common inter-lingual errors (the negative influence) committed by Arabic-speaking learners of English as Second Language (ESL). The study is based on Error Analysis (EA) of the essays of a group of English major undergraduate students from the University of Bisha, Al-Namas, Saudi Arabia. Contrastive Analysis Hypothesis (CAH)is included to predict most of the errors in the collected samples. The findings of the study show that common errors in the data are interlingual (54.03%). The errors within the Grammatical Category include the misuse of tenses, dropping the subjects, dropping verb to be-copular and word order misplacement. The majority of errors in the study are due to the interference of L1 linguistic system including the different orthographic, phonological,morpho-syntactic components. For instance, the participants’ dropping subjects in English can be attributed to the fact that Arabic as L1 and as Null Subject Language (NSL), unlike English, allows subject drop. The results also find that within the Lexical Category,preposition and article errors are the most frequent errors and that spelling errors are the most dominant errors within the Mechanics Category. The study gives some pedagogical implications and suggestions to avoid and minimize the interlingual errors of such type. For instance, teachers need to focus more on enlightening their students about the contrastive language systems from the early stage of learning ESL.展开更多

The results show that, during L2 vocabulary teaching process, the proper application of interlingual strategies can effectively facilitate the memorization of new words, and the bilingual method (both English explanation and Chinese translation) is welcomed by most subjects. Therefore, using L1 as a means of semantization or as a tool for checking and validating L2 learners' understanding of word meaning should not be completely rejected, especially for adult Chinese EFL learners.展开更多

Previous studies concluded that EFL learners tend to contains more personal involvement than native speakers in their writing, making it resemble spoken language as a result. Therefore, this paper examines the degree of W/R visibility in English writing by university-level Chinese learners to verify the applicability of the previous findings on Chinese learners. Based on the data collected in the corpora CLEC,WECCL and LOCNESS, the results show that Chinese EFL learners have the tendency to employ more features of W/R visibility than native speakers, for example the high use of first or second person reference and words that represent mental process. Besides, the paper also reveals little distinction on W/R visibility between English and non-English majors, suggesting the inefficiency of the writing ability of today's English majors.展开更多
