鉴于英语中由blend构词法产生的新词日益增多,这种独具特点的构词法应列为一种独立的构词法,其汉语译名亦应规范统一. 相似文献

An unexpected and remarkable preference for second language reading among some dyslexics has been noted, presenting a challenge to accepted theory on dyslexia and the capacity for second language learning. The current study was designed to examine this phenomenon by systematically looking at the differential reading scores in the first and second languages of reading-disabled young Swedish adults who claimed to prefer reading in their second language (English). Three groups were selected for study: a group of 10 reading-disabled young adults who prefer to read English; a second group of 10 reading-disabled with no special preference for second language reading, matched on word recognition efficiency, age group, gender and educational level and a group of 10 normal readers matched on age group and educational level. The test battery was designed to compare overall reading efficiency in English and Swedish and therefore encompassed both speed and accuracy measures. The battery covered seven phonological measures, four orthographic measures,three isolated word reading measures, two continuous text reading measures, a comprehension task and an author recognition task. All tasks were carried out in both English and Swedish. The results showed that two dyslexic groups differed significantly in the degree to which task performance, including reading efficiency, was impeded by the English format. A tentative hypothesis was forwarded as to how the exceptional and unexpected facility with English might be explained. 相似文献

跨越卡夫丁峡谷是马克思晚年提出的一个理论观点,从社会基本矛盾理论和中国革命的实践来分析,跨越卡夫丁峡谷是一个过程,该过程由“社会制度跨越”和“生产力补课”两个阶段构成,只有完成了两个阶段的跨越,才是实现了真正跨越卡夫丁峡谷的目标。“跨越过程论”论证了初级阶段的客观性、科学性及对建设有中国特色社会主义实践的重要指导意义。 相似文献

Topic evolution has been described by many approaches from a macro level to a detail level, by extracting topic dynamics from text in literature and other media types. However, why the evolution happens is less studied. In this paper, we focus on whether and how the keyword semantics can invoke or affect the topic evolution. We assume that the semantic relatedness among the keywords can affect topic popularity during literature surveying and citing process, thus invoking evolution. However, the assumption is needed to be confirmed in an approach that fully considers the semantic interactions among topics. Traditional topic evolution analyses in scientometric domains cannot provide such support because of using limited semantic meanings. To address this problem, we apply the Google Word2Vec, a deep learning language model, to enhance the keywords with more complete semantic information. We further develop the semantic space as an urban geographic space. We analyze the topic evolution geographically using the measures of spatial autocorrelation, as if keywords are the changing lands in an evolving city. The keyword citations (keyword citation counts one when the paper containing this keyword obtains a citation) are used as an indicator of keyword popularity. Using the bibliographical datasets of the geographical natural hazard field, experimental results demonstrate that in some local areas, the popularity of keywords is affecting that of the surrounding keywords. However, there are no significant impacts on the evolution of all keywords. The spatial autocorrelation analysis identifies the interaction patterns (including High-High leading, High-Low suppressing) among the keywords in local areas. This approach can be regarded as an analyzing framework borrowed from geospatial modeling. Moreover, the prediction results in local areas are demonstrated to be more accurate if considering the spatial autocorrelations. 相似文献

A recent Review of Teacher Education in Scotland reports that 23% of respondents (n = 2381) encountered variable or very poor school placement experiences. This paper uses Lave and Wenger’s ideas concerning Communities of Practice (1998) and Legitimate Peripheral Participation (1991) as analytical tools with which to understand the nature and impact of student teachers’ problematic experiences of school placement. A total of 14 Professional Graduate Diploma in Education students on a one-year Secondary English course were followed through the practice elements of their Initial Teacher Education programme and data were constructed from learning logs and semi-structured interviews. Analysis provided a nuanced account of the student teachers’ difficulties in attaining member status as Legitimate Peripheral Participants in communities of practising teachers, with the concepts ‘joint enterprise’, ‘mutual engagement’ and ‘shared repertoire’ being found to be useful in explaining these difficulties. Limitations in the theoretical framework were also discovered and these are highlighted and developed in the paper. 相似文献

伴随我国经济国际化进程的日益加快,国内企业纷纷走上了商标英语化的道路。而英语商标词汇不仅是商品的英文识别代码,同时也有着丰富而深刻的文化内涵,并通过词汇的音和义加以体现。英语商标的构思与设计一方面取决于英语词汇的构词规则,同时也受到商标使用地区风俗文化的制约。近期,国内出现的新浪(Sina)域名之争表明,渴望走向国际市场的中国企业虽然意识到国际化商标在其营销战略中的重要地位,但对英语商标词汇的文化内涵及构词规则还缺少足够的认识,致使所设计的英语商标词汇存在瑕疵,在使用中往往遭遇文化冲突,给企业和国家带来损失。 相似文献
