从输入输出理论看大学英语教学改革

本文以语言输入输出相关理论为基础,就大学英语教学改革实践,提出两点建议:(1)将传统的以精读为主的教学模式改为以泛读为主,同时采用难度适当的国内英文报刊为主要教学材料,取代传统的教材;(2)加大翻译教学比重;由此加强英语教学与现实生活的联系,为学生创造英语运用的条件和环境,从而改变目前大学英语教学中教学脱离实际,学生兴趣低迷的不利状况,更好地实现大学英语的教学目的。

Performance differences when using 26- and 29-inch-wheel bikes in Swiss National Team cross-country mountain bikers

The purpose of this study was to analyse the effect of bike type – the 26-inch-wheel bike (26“ bike) and the 29-inch-wheel bike (29“ bike) – on performance in elite mountain bikers. Ten Swiss National Team athletes (seven males, three females) completed six trials with individual start on a simulated cross-country course with 35 min of active recovery between trials (three trials on a 26“ bike and three trials on a 29“ bike, alternate order, randomised start-bike). The course consisted of two separate sections expected to favour either the 29“ bike (section A) or the 26“ bike (section B). For each trial performance, power output, cadence and heart rate were recorded and athletes’ experiences were documented. Mean overall performance (time: 304 ± 27 s vs. 311 ± 29 s; P < 0.01) and performance in sections A (P < 0.001) and B (P < 0.05) were better when using the 29“ bike. No significant differences were observed for power output, cadence or heart rate. Athletes rated the 29“ bike as better for performance in general, passing obstacles and traction. The 29“ bike supports superior performance for elite mountain bikers, even on sections supposed to favour the 26“ bike.

安徽R&D投入产出水平的实证分析

在国内外的研究基础上,结合安徽特有的基本情况,建立了一套评价安徽省各市R&D投入产出综合水平指 标体系,运用主成分分析和聚类分析,客观的评价了安徽省各地市R&D投入产出水平。评价结果表明,“合芜蚌”试验 区引领带动着全省R&D投入产出水平,“皖江带”城市R&D投入产出水平两极分化严重,而“皖北”地区则有崛起的势 头,从而为各市提升R&D投入产出水平提供参考依据。

边境口岸应对区域经济合作策略探讨——以凭祥口岸为例

区域经济合作的日益兴起给边境口岸带来新的发展机遇和挑战,采取正确的应对策略已迫在眉睫。在建设“南宁—新加坡”经济走廊的背景下,凭祥口岸面临功能定位、发展思路和发展战略的重新选择。因此,依托“南宁—新加坡”经济走廊,加快建设凭祥国际大口岸,就要加强硬件建设,提高通关效率,完善各项政策,为中国与东盟陆路的经贸合作创造便捷条件。     

论语言输入与外语习得

语言输入对外语习得的重要性已得到了普遍的认可.在国内外语言学家们所提出的理论和观点中,影响力最大的就是Krashen的"语言输入假设".本文主要以这一假设为理论根据,阐述了外语教学中语言输入的意义和如何进行语言输入.
