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。

Are you a budding academic writer?

Academic writing can seem a daunting prospect although with the right support and information it can be more achievable than you think. In this first set of editorial comments of 2016, editors from all sections of the Health Information and Libraries Journal outline the origins of the individual section of the journal which they oversee and highlight some of the things you might want to consider when thinking of submitting your writing for publication.     

从教学条件看信息技术教育的发展

通过对浙江省嘉兴、湖州两个地区部分中学的抽样调查,从教材和课时、教学设备、师资力量等多个方面分析我国中小学信息技术教育的现状.在分析过程中,除一般的对比说明外,还运用了Excel数理分析中的假设检验,对该学科在教学条件方面存在的问题做进一步揭示,并提出一些可行性建议.     

显性单纯致使句中的空语类

长期以来,汉语显性单纯致使句一直披上兼语句的外衣而隐藏了某些句法现象。本文首先从致使义入手将两者加以区分,在批驳"ECM"(例外格赋值)说或叫做"RtoO"(提升至宾语)说的基础上引入了Alboiu(2007)的"Feature Inheritance and Case Value"(特征传承)假说和"Null Expletive"(空虚指代成分)假说。在最简方案的框架下通过对显性单纯致使句的推导论证后我们得出结论,句中确实存在空语类,但它与兼语句中的PRO不同,而是一种新的空语类null expletive。     

从输入与输出角度看大学英语口语教学
