词汇语义探讨

语义问题是词汇研究的重心。本从词定义的模糊性、词的语义单位及单个词内的语义之间的关系及组织等三方面着手对词汇语义问题进行了探讨。     

Effects of tapering on physical match activities in professional soccer players

ABSTRACT

This study aimed to examine: (i) the effect of decreasing training load (TL) during taper weeks on physical match activities in professional soccer players, and (ii) to disclose the relationship between weekly TL and physical match activities. Rating of perceived exertion was collected after each training session and match to quantify the TL in 19 professional players over 17 standard and 7 taper weeks during the season. Physical match activities were quantified by a computerised match analysis system and compared between standard training and taper weeks. Compared to standard weeks, the duration and frequency of training sessions during the taper weeks decreased (?21.7% and ?18.8%, respectively; P < 0.01) with no change in intensity (?4.8%; P = 0.09). Consequently, the weekly TL decreased during the taper weeks (?25.5%; P < 0.01). Increases in distance covered by intense running (+15.1%; P < 0.05), high-intensity running (HIR) (+15.7%; P < 0.01), number of sprints (+17.8%; P < 0.05) and number of high-speed runs (+15.7%; P < 0.05) were observed during the seven matches played after the taper weeks. High relationships were observed between TL and HIR distance covered, number of HIR and number of sprints (r = ?0.53; r = ?0.55; r = ?0.65, respectively; P < 0.01). Decreasing TL during taper weeks by reducing training duration and frequency but maintaining intensity was associated with an increase in physical activities during matches. However, it needs to be determined whether tapering or other match factors led to the changes in match activity.

论形式能否拯救新诗

由于新诗的日益边缘化处境,诗坛上流行着一种"形式拯救诗歌"论,这种提法有失偏颇。因为:一、从新诗发展历史考察,自由诗同格律诗一样,取得过辉煌的成就;二、从诗歌本质看,诗之所以为诗,根本在于蕴含情感和节奏,而它的节奏有外节奏和内节奏之分,自由诗倾向于内在情绪节奏;三、诗歌在当今时代衰落的根本原因并不在于诗歌形式建设方面的问题,而在于时代所造成的一代人紧张而浮躁的心理状态。所以,严格的形式要求并不能充当新诗的救赎之神。

幼儿研究性活动与教师角色的定位

幼儿研究性活动不同于一般的“主题“活动和中小学研究性学习,其自身的特征决定了幼儿教师应扮演多重角色,即正确教育理念的构建者,环境的创设者,幼儿活动的引导者、支持者、观察者,教育实践的研究者,活动方案的设计者.
