预制语块与大学英语作文教学

通过预制语块的研究成果,从二语习得的角度,论述了预制语块在英语作文教学中的三个优势。利用预制语块进行作文教学,教师要转变教学观念,传授语块学习的知识和策略,鼓励学生“死记硬背”,以及增加语块输出机会,这样才能为大学英语作文教学找到新的思路。     

一种全局QoS感知服务组合的权重设计方法

基于全局QoS感知的服务组合可以通过加权聚合的方式构建为一个单目标优化问题,此时需要一个合适的方法去估算权重,为此提出了一种基于非均匀空间理想加权距离的权重合成方法.该方法考虑用户的全局定性需求,首先运用G1法生成主观权重,然后使用熵权法计算各组合点上QoS属性的内在客观权重;最后给出非均匀空间距离计算方法,结合逼近理想法设计合成权重.构建于QWS数据集上的实验,阐述了合成权重的计算过程和评估了相关参数对权重的影响.结果表明,合成权重能够综合反映用户的偏好和QoS属性的内在特征.     

《文心雕龙》文评论新探

《文心雕龙》文评论的范围应包括文评论的理论基础、文评论的主体，由文评论、创作论中择选出来的代表性篇章。这三个部分有机结合，形成了一个相对完整的理论体系。《文心雕龙》文评论具有文评论与创作论结合、鉴赏与批评结合、批评标准与批评方法结合、肯定与否定结合、分散与集中结合、批评与现实结合的特点。这些特点标志着《文心雕龙》文评论所达到的理论高度。     

论绘画语言的组织形式

在绘画艺术中,构图是作品的关键所在,是画面的基本形式与结构,是绘画语言的核心。这种绘画语言的组织形式不仅决定作品的性质,而且决定作品的视觉效应和感染人的程度。没有那一个因素像构图一样,与绘画作品的思想、构思、情节联系的这样紧密。构图是绘画作品中全部艺术语言的组织方式,是检验构思视觉效果的依据,是揭示形象的全部艺术语言的总和。     

论篇章结构教学法与短文写作

文章探讨了篇章结构教学法的特点，分析了篇章结构教学法适应的范围及条件，并根据教学实践的经验积累，把在英文短文写作中的中西方思维方式作了对比，提出了篇章结构教学法在英文短文写作中的实施建议与注意问题。     

体育院校冰上运动对男大学生身体成分和骨密度的影响

为探讨冰上运动项目对男大学生身体成分和骨密度的影响,采用韩国ZEUS9.9身体成分分析仪和法国Osteospace MEDI LINK超声骨量测量仪,分别对体育院校2010～2012级冰上运动专项的男大学生和没有运动专项的男大学生进行身体成分和骨密度的测量,并对实验数据进行统计学的分析与比较。结果显示,冰上运动专项男大学生左右腿肌肉含量、基础代谢率显著高于对照组（P＜0.05）,骨密度显著低于对照组大学生（P＜0.05）,这可能与调查对象的生活方式、饮食习惯、训练年限、运动水平以及冰上运动项目的教学内容有关。建议冰上运动专项男大学生改变不良生活方式、均衡饮食,适当调整运动训练方案,加强下肢的力量训练,提高运动成绩。     

Multiple components of fitness improved among overweight and obese adolescents following a community-based lifestyle intervention

Fitness is an important component of health, and obese adolescents regularly have poor fitness. Unfortunately, few have assessed the impact of community-based lifestyle interventions on multiple components of fitness. The purpose of this study was to assess the impact of participation in a community-based intervention involving adolescents and parents on multiple components of fitness of obese adolescents. In a within-subject, waitlist controlled clinical trial with 12 months follow-up in Western Australia, participants (n = 56) completed multiple fitness measures at baseline, immediately prior to beginning an 8-week intervention and at 3, 6 and 12 months during a maintenance period. Performance on the shuttle walk was improved immediately post-intervention (increase of 42.8 m, 95% CI: 7.5, 78.2) and at 12 months post-intervention (increase of 44.6 m, 95% CI: 1.3, 87.8) compared with pre-intervention. Muscle performance of quadriceps and deltoids were improved post-intervention (increase of 1.1 (95% CI: 0.1, 2.1) kg · F and 1.0 (0.02, 2.1) kg · F, respectively) and all muscle performance measures were improved at 12 months following the intervention. There were no changes in waist circumference. A community-based lifestyle programme such as Curtin University’s Activity, Food and Attitudes Program (CAFAP) may be a viable strategy for improving fitness in overweight adolescents.     

Effects of interval aerobic training combined with strength exercise on body composition,glycaemic and lipid profile and aerobic capacity of obese rats

The purpose of this study was to investigate the effects of interval aerobic training combined with strength exercise in the same training session on body composition, and glycaemic and lipid profile in obese rats. Sixteen lean Zucker rats and sixteen obese Zucker rats were randomly divided into exercise and sedentary subgroups (4 groups, n = 8). Exercise consisted of interval aerobic training combined with strength exercise in the same training session. The animals trained 60 min/day, 5 days/week for 8 weeks. Body composition, lipid and glycaemic profiles and inflammatory markers were assessed.

Results showed that fat mass was reduced in both lean and obese rats following the exercise training (effect size (95% confidence interval (CI)) = 1.8 (0.5–3.0)). Plasma low-density lipoprotein–cholesterol and fasting glucose were lower in the exercise compared to the sedentary groups (d = 2.0 (0.7–3.2) and 1.8 (0.5–3.0), respectively). Plasma insulin was reduced in exercise compared to sedentary groups (d = 2.1 (0.8–3.4)). Some exercise × phenotype interactions showed that the highest decreases in insulin, homeostatic model assessment-insulin resistance, fasting and postprandial glucose were observed in the obese + exercise group (all, P < 0.01). The findings of this study suggest that interval aerobic training combined with strength exercise would improve body composition, and lipid and glycaemic profiles, especially in obese rats.
