A Formalistic Analysis of Poe’s Poem-"Annabel Lee"     

张慧慧 《海外英语》2011,(9):318-319

Edgar Allan Poe is one of the few writers in the history of American literature who develops not only good novels and poems but also excellent critic theories.In Poe’s criterion,the poem should be short,and produce a feeling of beauty in the reader."Annabel Lee" is a perfect illustration of Poe’s poetic theories.The essay analyzes the poem in detail from the formalistic point of view.  相似文献

高校辅导员在集体场合讲话的修辞形式     

张金发 《邵阳学院学报(社会科学版)》2011,10(5):65-68

对于当前规模越来越大、个性越来越鲜明的大学生群体来说,辅导员能否采用最科学、最合理的讲话方式,将直接影响着大学生对辅导员讲话的接受效果。影响辅导员在集体场合讲话效果的,不仅包括讲话的内容和形式,还包括辅导员的公正、平等、真诚、言行一致等话语外因素。辅导员要让讲话有说服力,有吸引力,就不仅需要斟酌讲话内容,还必须合理地使用各种修辞方法,才能最终取得良好的教育管理效果。  相似文献   

Fantastic Application of Foreshadowing and Irony in A Good Man Is Hard to Find     

张科 《读与写:教育教学刊》2011,(5):11+24

Mary Flannery O’Conner utilizes the literary devices of foreshadowing and irony(dramatic,situational and verbal) in her short story A Good Man Is Hard to Find to convey and emphasize the concepts that we each experience reality,however skewed,through the unique,sometimes morally-distorted lens of individual perception.The application of the literary devices certainly contributes a lot to the presentation of the profound import Flannery intends to express in her novel.  相似文献   

英语仪式性演讲的汉译研究:文本类型理论视角     

邓文婷  张凌 《鸡西大学学报》2015,(1):79-82

根据演讲的目的,可以将演讲分为知识性演讲、说服性演讲、仪式性演讲等几类。仪式性演讲在各类特殊场合扮演着重要角色。随着国际交流日趋频繁,仪式性演讲的翻译也显得至关重要,理应引起重视。仪式性演讲作为一种集实用性和艺术性于一体的特殊文本,对其翻译应有特殊的方法,这正是文本类型理论的内涵所在。拟以赖斯的文本类型理论为指导,结合实例,从音韵修辞、语义修辞和结构修辞三个层面探讨仪式性演讲的汉译,希望为演讲英语的汉译研究提供新的视角。  相似文献   

修辞在潜语言显化过程中的作用——以网络流行语为例     

王亚媛 《牡丹江教育学院学报》2010,(5):27-28

根据潜显理论,语言的存在形式有潜态和显态两种。潜态的语言包括潜词、潜句、潜义及潜语法等多种存在形式。当前的网络流行语中,小至字词层面,大至句段层面,存在着大量的潜语言显化现象。本文以＂杯具＂等网络流行语为例,分析修辞在潜语言显化过程中的作用,并指出潜语言显化常用的修辞手段。  相似文献

英汉语强调方式的对比分析     

甘露  甘霖 《阜阳师范学院学报(社会科学版)》2010,(2):50-53

强调可以突出地表达说话者的意旨、情感、态度,可以使语言更加富有感染力,使听者或读者能更快捷、深刻地理解和掌握交流的信息。英语、汉语尽管属于不同的语言形态,但都存在强调的语言现象。本文将就这两种语言中存在的强调的表达方式作一番对比分析,从而有助于人们对这两种语言中强调方式的学习,并进一步说明这两种语言的特点。  相似文献   

Indirect estimation of cable tension during gymnastic movements on rings     

Mark?A.?BrewinEmail author  David?G.?Kerwin 《Sports Engineering》2003,6(3):177-185

Knowledge of external forces acting on an athlete is often required to study performance and injury mechanisms, but direct measurements are difficult to obtain. While transducers in the rings cables typically measure external forces experienced by gymnasts performing static balances and swinging movements on rings, this solution is not always acceptable and an accurate technique that does not hinder the gymnasts’ performances is desirable. This study evaluates a video-based technique for estimating cable tension on the rings apparatus. Static loading of a rings frame coupled with a planar video analysis of the mandatory damped elastic devices (DEDs) provided a tension-deflection calibration curve. Three-dimensional video and cable tension data were obtained for two male gymnasts performing static balances and dynamic swinging movements. Cable tension was measured using a force link while a planar video analysis determined time histories of the DED deflections. Combined cable tension time histories were estimated fromrelative DED deflections coupled with the tension-deflection calibration curve and the orientation of the rings cables, and were compared to measured values to evaluate the proposed technique. For static balances the RMS difference between measured and estimated combined cable tension was 83 N. For dynamic swinging movements the maximum RMS difference was 189 N, equivalent to a 4% difference when expressed as a percentage of the peak value. The indirect video-based technique developed in this study accurately estimates combined cable tension throughout movements on rings and may be considered for studies where a remote measurement is required. There is potential for the technique to be extended to other sporting situations, where indirect accurate estimates of external forces acting on an athlete are needed.  相似文献
