Analysis on Subtitle Translation in Forrest Gump     

侯爽 《海外英语》2011,(10):188-191

Subtitle translation industry requires the translator to understand that culture and master the translation skills. This subtitle translator can better and more easier to understand. Of course the subtitle translation must have profound understanding about culture. However, in the process of translating, sometimes even a word, also can’t just straightforward translated, so the translation skills is especially important in words mainly through the processing of the use of the techniques, including the add or remove meaning, double negative, digital processing, literal translation, the understanding of the culture in the subtitle translation, and subtitle translation reflect some of the features, and restrictions, including time space restrictions. Through the literature retrieval, analysis and understanding of the principles of subtitle translator and characteristics of the system, it comes the conclusion, that the language is affected by cultural influence and restriction, and colleagues culture industry affects the development of language.  相似文献   

植物叶片中叶绿素提取方法的比较研究     

李志丹  韩瑞宏  廖桂兰  张美华 《广东教育学院学报》2011,(3):80-83

利用12种植物材料,应用分光光度法对分别以丙酮和乙醇作为提取剂,并同时各采用研磨与浸泡两种方法的叶绿素含量测定值进行比较研究.结果显示,4种方法测定的植物叶片叶绿素含量均具有一定的相关性,其中,乙醇浸泡法与乙醇研磨法的相关程度最高.且用乙醇作为提取剂测定植物叶片叶绿素含量比较稳定,尤其用乙醇浸泡法测定的人为误差相对较小.  相似文献   

建立医学领域研究型博士学位评价标准的探讨——应用德尔菲法的尝试     

陈建俞  刘少雪 《教育与现代化》2011,(5):54-59

医学领域研究型博士学位评价是对博士生经过3～5年学习之后形成的最终学习成果进行价值判断。为了探究医学领域研究型博士学位评价标准,我们采用德尔菲（Delphi）法,对22名专家进行两轮咨询。研究结果初步确立了医学领域研究型博士学位评价体系,包含4大要素、25项评价指标。本研究不仅为社会评价医学领域研究型博士学位提供统一的参考标准和导向,还为高校授予医学领域研究型博士学位提供一套实用的工具。  相似文献

基于语言符号象似性特征的科技新词翻译     

张小波 《太原理工大学高等教育研究》2006,24(3):20-23

通过对语言符号的任意性和象似性的特征进行分析，指出在创造科技新词时，语言符号的象似性使新词更有理据。因此，在翻译时以语言符号的任意性和象似性的辨证观为基础，从象似性的角度考虑英汉语的符号对等是切实可行的。  相似文献   

Evaluating a technology supported interactive response system during the laboratory section of a histology course          下载免费PDF全文

Vera D. Rinaldi  Nancy A. Lorr  Kimberly Williams 《Anatomical sciences education》2017,10(4):328-338

Monitoring of student learning through systematic formative assessment is important for adjusting pedagogical strategies. However, traditional formative assessments, such as quizzes and written assignments, may not be sufficiently timely for making adjustments to a learning process. Technology supported formative assessment tools assess student knowledge, allow for immediate feedback, facilitate classroom dialogues, and have the potential to modify student learning strategies. As an attempt to integrate technology supported formative assessment in the laboratory section of an upper‐level histology course, the interactive application Learning Catalytics^TM, a cloud‐based assessment system, was used. This study conducted during the 2015 Histology courses at Cornell University concluded that this application is helpful for identifying student misconceptions “on‐the‐go,” engaging otherwise marginalized students, and forming a new communication venue between students and instructors. There was no overall difference between grades from topics that used the application and grades from those that did not, and students reported that it only slightly helped improve their understanding of the topic (3.8 ± 0.99 on a five‐point Likert scale). However, they highly recommended using it (4.2 ± 0.71). The major limitation was regarding the image display and graphical resolution of this application. Even though students embrace the use of technology, 39% reported benefits of having the traditional light microscope available. This cohort of students led instructors to conclude that the newest tools are not always better, but rather can complement traditional instruction methods.

对小组合作学习过程中几个问题的思考   总被引：2，自引：0，他引：2  

王小卫 《甘肃高师学报》2007,12(4):91-93

合作学习是我国新一轮课程改革所倡导的一种重要的学习方式,小组合作学习是其基本形式。在实际教学中,部分教师只注重了合作学习的形式而违背了合作学习的实质,具体表现为在合作学习目标的确立、合作小组的组建、小组成员的评价策略以及对教师自身的职责认识等方面存在许多误区。结合目前的研究成果和本人长期的教学实践,在分析对小组合作学习过程中存在的几个问题的基础上,进行了相应的对策思考。  相似文献   

用新的审美范式构建艺术世界--论新现实主义小说的表现方法     

李继林  孟方 《唐山师范学院学报》2004,26(1):20-26

新现实主义小说继承和发展了现实主义的创作精神和表现手法，并根据时代的发展和人民的审美需要而增添了审美新质。它以直面人生的创作态度和严格写实的风格表现时下的生活和人民的心态，以“世俗化”的手法描绘世相，以大众化的审美形式与人民大众接轨。它还积极地吸纳各种创作模式和大胆地借鉴运用其他创作方法的创作技巧，以丰富现实主义的创作方法。  相似文献
