论交往教学的要素

教学要素是教学论研究的基本理论问题。传统教学要素观是以主知主义为思想基础的 ,分类混乱 ,混淆了“因素”与“要素” ,模糊了“要素”与“系统”的界限 ;交往教学的要素由主体要素、客体要素和教学物资三个基本要素构成的 ,它们又分别表现为多种形态。研究交往教学要素具有重要的理论意义和实践价值

状态形容词的韵律特征

状态形容词在功能上不同于性质形容词,韵律上也和性质形容词不同。状态形容词是在性质形容词基础上形成的,在使用频率上,性质形容词的常用性使其在韵律上形成"重轻"的格式,而状态形容词韵律格式是"轻重",这是由状态形容词的自身特点决定的。

Effects of different weight loss intervention programmes in health clubs – an observational multicenter study

This study aimed at comparing the effectiveness of three lifestyle intervention programmes in health clubs “exercise only” (E), “exercise plus nutritional counselling” (E?+?NC), and “exercise plus weight loss program” (E?+?WLP) on weight loss under real-life conditions. An observational multicenter study including 788 overweight/obese new customers of 95 health clubs in Germany was performed. Participants chose E (n?=?512, 38?±?14?year, BMI 30.4?±?4.7?kg/m²), E?+?NC (n?=?179, 42?±?14?year, BMI 31.7?±?4.5?kg/m²), or E?+?WLP (n?=?97, 40?±?11?year, BMI 31.6?±?5.1?kg/m²). Anthropometric data, energy expenditure, and energy intake were assessed at baseline and after 3 months. All groups significantly reduced body weight (E: ?1.5?±?2.9?kg, E?+?NC: ?3.4?±?3.6?kg, E?+?WLP: ?5.5?±?4.3?kg, p?p?p?相似文献   

Association of physical activity with risk of metabolic syndrome: findings from a cross-sectional study conducted in rural area,Nantong, China

The prevalence of metabolic syndrome increases rapidly worldwide, and its association with physical activity (PA) varies with race and lifestyles. Little is known about the association in rural China. The Nantong Metabolic Syndrome Study recruited 13,505 female and 6997 male participants in 2007 and 2008. Socio-demographic characteristics, and physiological and behavioural data were collected. Logistic regression model was applied to estimate associations of metabolic syndrome and its components with different PAs. The overall metabolic syndrome prevalence was 21.6% in current study. Increasing total PA or moderate-to-vigorous-intensity occupational PA was associated with decreasing 5%–60% risk of having metabolic syndrome and abnormal metabolic syndrome components in both genders. An association between leisure-time PA and blood pressure was found in men, but no associations between leisure-time PA and metabolic syndrome components were found in women. Commuting PA, such as walking and taking bus, by bicycle and walking only, was associated with decrease of 20%–45% risk of several abnormal metabolic syndrome components in women. This study provides information for future investigation into the nature of these associations so that recommendations can be developed to reduce the prevalence of metabolic syndrome and its components among rural population in China.

词汇知识对口语交际的影响研究

本研究旨在调查词汇知识在口语交际中的作用。重点考察词汇知识的三个基本层面,即语音层面、词的形、义层面,搭配层面。通过同口语交际中其他方面知识(如语法知识,语义知识,语用知识)的比较,发现词汇知识是经常影响到口语交际的重要因素。对语义的理解则是影响口语交际的必然因素。本研究的语义仅指完整的话语之意义,以区分词汇意义。而在词汇知识方面,对词汇意义的理解和掌握对口语交际具有重大影响。其教学意义是:大学英语教学应该注重扩大学生的积极性词汇(应用性词汇),把学生培养成目的语的积极使用者,而不是消极或被动的接受者。
