大学英语写作训练模式探讨     

罗燕子 《天水师范学院学报》2004,24(4):99-101

目前,我国学生在大学英语写作中的问题主要在于措词、语法知识、语篇衔接以及文章主题方面;针对以上问题,笔者结合教学实践,探讨了四种大学英语写作训练模式:一是词———句———段模式,二是主题句———支撑句———扩展句模式,三是引言———主体———结论模式,四是阅读———讨论———写作模式。这四种训练模式在重视训练学生基本功即遣词造句能力的同时,兼顾大学英语写作技巧的训练,旨在帮助学生提高大学英语的写作水平。  相似文献   

东汉都邑赋家话语策略的成因及其模式     

刘向斌  侯立兵 《宁夏师范学院学报》2004,25(2):11-18

东汉都邑赋家的话语策略成因有四：统治者的政治需要；都邑功能的转变；西汉赋家的率先垂范；儒家经典意识的导向。受其影响，东汉赋家们的话语策略因时代不同而具有明显的差异性，具有三种不同的模式：前期赋家追寻历史依据以示慎重；中期赋家假借虚构人物以述己意；末期赋家则关注世俗生活以示冷漠。  相似文献

A survey of Web-based business models for e-government in the Netherlands     

Marijn Janssen  George Kuk  René W. Wagenaar 《Government Information Quarterly》2008

Governments worldwide are increasingly using Web-based business models to enhance their service delivery. Yet the concept of the business model is unexplored within the context of e-government. Drawing upon the literature on e-commerce, we develop a taxonomy for analyzing Web-based business models for e-government. Based on a systematic survey of 59 e-government Web sites in the Netherlands, our findings indicate that most of the Web sites use the content provider or direct-to-customer business models, while only a few are using novel business models. Overall, the concept of business model is appealing and useful in the public sector. Specifically it compliments research on Web site quality by analyzing and describing Web sites using atomic e-government business models and suggesting improvements by using combinations of business models.  相似文献

Key somatic variables associated with,and differences between the 4 swimming strokes

ABSTRACT

This study identified key somatic and demographic characteristics that benefit all swimmers and, at the same time, identified further characteristics that benefit only specific swimming strokes. Three hundred sixty-three competitive-level swimmers (male [n = 202]; female [n = 161]) participated in the study. We adopted a multiplicative, allometric regression model to identify the key characteristics associated with 100 m swimming speeds (controlling for age). The model was refined using backward elimination. Characteristics that benefited some but not all strokes were identified by introducing stroke-by-predictor variable interactions. The regression analysis revealed 7 “common” characteristics that benefited all swimmers suggesting that all swimmers benefit from having less body fat, broad shoulders and hips, a greater arm span (but shorter lower arms) and greater forearm girths with smaller relaxed arm girths. The 4 stroke-specific characteristics reveal that backstroke swimmers benefit from longer backs, a finding that can be likened to boats with longer hulls also travel faster through the water. Other stroke-by-predictor variable interactions (taken together) identified that butterfly swimmers are characterized by greater muscularity in the lower legs. These results highlight the importance of considering somatic and demographic characteristics of young swimmers for talent identification purposes (i.e., to ensure that swimmers realize their most appropriate strokes).  相似文献
