Previous studies indicate that the web-based learning can improve learners' autonomous learning, as well as some problems found in their findings. Therefore, this paper first gives a summary and critique of research studies on the web-based autonomous learning and some factors influencing learners' autonomous learning ability;then, areas that deserve further study are also indicated.展开更多

Via using Longman Learners Corpus, British English 2006 and American English 2006, quasi-modals used in English language learners’ writings are compared with the real uses of quasi-modals in native speakers’ writings. The results show that English languagelearners may have a problem with misusing colloquial-feature phrases, quasi-modals, in written registers.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
