英汉交替传译中的预测机制

英汉交替传译需要口译员运用多种能力和技巧来完成听、理解、记忆信息再表达的过程,而积极听力技巧在整个口译的过程中起到至关重要的作用。但是由于发言者本身以及口译员本身的诸多因素,经常出现信息遗漏或者信息理解错误的情况。然而通过预测手段的使用,口译员可以最大限度地预测演讲者陈述的信息,更好地完成口译任务。本文陈述了关键词预测、连贯手段、语调预测、冗余预测四种言内预测手段和交际场预测以及文体风格预测两类言外预测手段,以期给口译工作者带来一定的启发和帮助。

试析铁饼技术教学中的技术强度

铁饼技术是一项较为复杂的技术，人们在教学实践中总结出许多宝贵的经验，但目前我国体育院校培养出的田径专业学生，普遍存在着对铁饼完整技术理解不深，也做不出一个质量较高的铁饼完整技术，本文通过对运动技能形成过程中的生理学、心理学的深入分析，指出运动技能的动态性而提出“技术强度”概念，以期能对铁饼技术教学有一个更深入的了解。     

Comparisons of the ski turn techniques of experienced and intermediate skiers

We compared selected kinematic variables for four different ski turn techniques performed by five experienced and five intermediate male skiers. The four ski turn techniques were the upstem turn, the downstem turn, the parallel turn and the parallel step turn. Each turn was divided into the initiation phase and the first and second steering phases. Most of the statistically significant differences (P < 0.05) between the two groups were found for the initiation phases of the four turns. Both the hip axis-hand axis angle and the edging angle of the uphill ski were significantly different between the two groups for the upstem turn at the beginning of the initiation phase. For the downstem turn, significant differences between the groups were found at the start of the initiation phase for the hip axis-hand axis angle, the shoulder axis-fall line angle, and the edging angle of the uphill ski. The standard deviation of the distance between the tips of the two skis over the second steering phase also differed significantly between the two groups. For the parallel step turn, significant differences were found at the start of the initiation phase for the edging angle of the downhill ski and the downhill ski to movement direction angle. Significant differences were also found for the edging angle of the downhill ski in the middle of the second steering phase and the shoulder axis to movement direction angle at the end of this phase. For the initiation phase of the parallel turn, significant differences were found for the timing of setting the ski pole, the uphill knee angle at the start of this phase and the range of the knee angle of the uphill leg from the start to the end of this phase. For this turn, significant differences between the two groups were also found for the edging angle of the downhill ski in the middle of the second steering phase and the shoulder axis to movement direction angle at the end of this phase. One of the reasons it was possible to identify a few significant differences only for the turns analysed, was the variability within the intermediate group: for most of the variables analysed, the standard deviation was much higher for the intermediate than for the experienced group.
