写在浪漫主义时期尾声的辉煌之作——以拉赫玛尼诺夫《第二钢琴协奏曲》为例

作为浪漫主义最后一位伟大倡导者,他的作品旋律优美流畅,音乐内涵丰富。其代表作《第二钢琴协奏曲》有着阴森的背景、沉重的低音,这是作曲家当时彷徨、苦闷心情的真实写照,具有坚实的结构和巨大的感染力,本文分析了该曲各个乐章的音乐特点。     

第二语言习得中普遍语法的可及性--"根本差异假说"引起的反思

自从乔姆斯基于八十年代提出了原则和参数理论,普遍语法理论已被广泛地应用于第二语言习得研究领域,并迅速成为解答二语习得中逻辑问题的主流学说。但是二语习得与母语习得之间存在的巨大差异,使诸多学者对普遍语法在二语习得中的地位和作用提出了质疑,而普遍语法可及性便成为争论的焦点。文章对其中影响较大的根本差异假说进行了分析,讨论了其在理据上的不足,指出了目前普遍语法理论框架的优势和局限,探讨了走出研究困境的出路。

中国近代师范教育专业性特征考略——以直隶省立第二师范学校为例

中国近代师范教育始于十九世纪末,其后经历了从思想认识到实践探索再到独立体系初步建立的过程。在这过程中,近代师范教育形成了诸多方面的专业性特征,其专业性特征对当今师范教育的发展有着重要价值。     

单输入单输出系统模型的自适应控制

系统的传递函数模型与时域动态模型都可以描述单输入单输出线性系统,从数学上说,利用这两种模型描述同一个系统是等价的,但是,对于带有不确定参数的系统输出跟踪问题,基于系统时域动态模型的控制设计方法显得更加直接而有效。针对带有不确定参数的一、二阶线性系统,利用微分方程稳定性理论设计了自适应跟踪控制器。     

试析排球二传手的视野

通过抽样测试,表明部分运动项目运动员视野的现状及差异,造成这种差异是因为运动范围和运动目的。通过测试二传手的视野范围大于扣球手。本文阐述二传手在排球场上所起的特殊作用以及如何提高和由大视野范围。因为二传手视野广能在比赛中有效地组织高水平的战术球,这是赢得胜利的必要条件。     

Information needs of students in Israel — A case study of a multicultural society

Students turn to a variety of sources when searching for information for their academic assignments. This study uses findings from a survey given to 151 Israeli students attending a university in Israel. A questionnaire comprising 12 questions was administered regarding their information needs, information behavior, and difficulties in searching and writing an academic assignment. A special emphasis of the study was on the multicultural environment of the Israeli students and its effect on their information behavior. Results show that there is a significant difference between native language groups with regard to the use of search engines, the use of library services, and in the patterns of conducting their academic assignment.     

Our enemy's enemy

This article focuses on representations of Britain to occupied France by the BBC French Service via its flagship programme Les Français parlent aux Français [The French speak to the French]. It first examines the establishment of the service and the formulation of a British propaganda strategy on occupied France. It then explores the service's efforts to foster French belief in Britain as France's friend and ally, and to rationalise key issues and incidents which challenged that narrative. Simultaneously, it positions French Service endeavours alongside the propaganda delivered on French national radio, known as Radio Vichy, in order to explore the exchanges about Britain between French propagandists who spoke on behalf of different Frances. In so doing, the article provides a close reading of the original French Service broadcasts which covers a larger corpus of material than has hitherto been documented in published collections, and which extends existing knowledge on the topic.

外语教学与跨文化语用能力的培养

跨越不同文化背景的人。即使双方发音正确，懂得语法。掌握相当数量的词汇。有着较好的语言水平。在交际中也经常会发生故障。这是由于双方对彼此的社会文化传统缺乏了解。以及他们的说话方式或习惯不尽相同所造成的语用失误。本文从外语教学入手．探讨在外语教学中如何培养学生的跨文化语用能力。
