The absorption to aN was best to perennial ryegrass while nN to barley. According to the differential analysis of N content, treatments of both aN and nN was nitrogen superfluous, which led to release excessive N to the atmosphere, and the rainwater treatment and the control were N deficient, the largest N absorption from atmosphere was 0.698 g in rainwater treatment.[Conclusion] Average N use efficiency contributed by atmosphere N deposition ranged from 1.321%-6.116%, while the control of barley had the highest of 6.116%.展开更多

Sample included 67 first year university undergraduates. All the 67 students considered prior knowledge of the high school five-paragraph essay writing style helpful. They believed that it facilitated a transfer of learning in the first-year university undergraduate academic writing course. However, only 15 out of the respondents, who reported that prior knowledge of the high school English language five-paragraph essay writing style was helpful, also reported that they are level-appropriate competent in the first-year university undergraduate English language academic writing courses after one academic year. As such, essay-writing in high school offers students some foundation-knowledge to succeed in academic writing in universities. Further findings showed that students often delve into essay or academic writing without proper planning. Thus, it is recommended that universities introduce a bridge course specifically to address academic deficiency in reading and writing for all first year undergraduates upon admission into the university.展开更多

It lays solid foundation for their future study and work. Yet serious problems exist during the process. The author of the paper collects and analyzes the 289 titles of English majors＇ B.A. writing in the recent two years in Changchun University, China. The results of the analysis reveal that almost 40% of the titles are on literature every year and among them there are some similar titles. In view of this situation, the author first explores the reasons that caused those problems. One of the important reasons is that the increasing of the supervisors and reference materials cannot keep the pace of the expanding of students＇ numbers. The author, after that, makes some reflections on those problems, then proposes five practical supervising strategies, and makes some relevant suggestions for English major＇s thesis writing. Meanwhile some other related problems in thesis writing in China are also discussed.展开更多
