Different from previous research that explored reading while listening for listening development, this study combined the two skills in dictation in which listening was a continuation of reading. Participants were two groups of firstyear Chinese EFL learners who were exposed to the target language under two conditions: the traditional dictation(i. e., listening-only) and the reading-listening integrated dictation in a counterbalanced order. Three datasets were collected: listening performance, perception questionnaires and follow-up interviews. Results indicated that the reading-listening integrated dictation was superior in terms of learning gains from listening and that their effect was commensurate with dictation text difficulty. The findings also showed that the reading-listening integrated dictation could enhance EFL students’ confidence and interest and make the use of strategies possible during listening.展开更多

Then it expressed in E. coli BL21 (DE3), and His-tag fusion protein of high yield was obtained. It was found that the fusion protein existed in E. coli mainly as inclusion bodies. The bioinformatics analysis indicates that LCN61 is C2H2 type zinc-finger protein containing four C2H2 zinc-finger motifs. This work provides a theory for functional research of lcn61 gene.展开更多
