Application of the Closed-Captioned Pictures to the English Text Books

我们的项目主要针对大学生的英语教材，旨在将带有隐藏式字幕的视频和激光光盘应用于教材中。在美国逗留期间，我们的一些成员遇到了为听力障碍者和非英语母语者提供的闭路字幕系统，并知道它可以很容易地进入个人电脑，并可以用文字处理器进行修改。从1994学年开始，我们用三年时间，对《大学英语》教材进行了开发，并在课堂上试用，观察学生的反应，评估其效果，与教师讨论，并加以改进。在我们的课堂上，带字幕的课本激发了语言训练的巨大动力，主要是因为学生们对真实的、最新的、令人兴奋的内容感兴趣，例如带有商业广告的美国电视节目。然而，快速的语言，口语表达，俚语，双关语，特殊的口音和方言等都是学生跟上课文内容的障碍。在我们的项目结束时，我们一致认为，隐藏字幕可以是相当有效的语言课本材料，前提是我们不能太注意隐藏字幕文本的能力，训练的目的（阅读、写作、听觉交流等），适当的介绍和注释的词汇和短语，和背景的评论。它可能很快就有可能有基本的文本从封闭式字幕在互联网上，这是由每个语言教师自由处理，如果文本thas没有版权的问题。

Our project aimed at an application of the videos and laser discs with closed-captions to the English text book mainly for college students. During the stay in the US,some of our members have encountered with the closed caption system for the auditory handicapped people and non English speaking pepole, and knew that it can be easily taken into personal computers and be modified with word processors. We found that it has so great a potentiality to be applied to be used as foreign language text book for college students.For three years from the 1994 academic year, we developed the text books, tried them in our classes, observed the students'reactions, estimated the efficiencies, discussed what we found with cach oter, and improved them.Generally, closed caption text books roused a gerat motivation to the language training in our classes, chiefly because of the students'interest in the contents which is real, up-to-date, and exciting ; American TV programs with commercials, for example. Yet, rapid speech, colloquial expressions, slung, jole, pun, peculiar accents, and dialects, etc. are the hindrances for the students to catch up with what is gong on in the texts.By the end of our project, we agreed that closed captions could be quite efficient materials for the language text book, provided that we cannot be too careful about the aptitude of the closed caption text, purpose of the training(reading, composition, aural communication, etc.), appropriate introductions and notes on the vocabulary and phrases, and background commentary.It may soon be possible to have basic texts from closed captions on internet, which is to be freely procedded by each langeuage teachers, if the tex thas no problem with copyright.
