从《五体清文鉴》满语构词附加成分——tu看蒙古语对满语的影响

该文认为满语构词附加成分-tu很可能来源于蒙古书面语，是在满蒙书面语的相互接触和影响过程中由蒙古语借入满语的。由此，可以看出蒙古书面语对满语产生了很大的影响。     

连分式算法插值顺序的有效安排

n节连分式算法是一个实用的一维搜索方法。构造连分式插位函数时,部分分母的计算在该算法中占有较大的比重,本文通过对插值点先后顺序的有效安排,使得部分分母的计算量下降近三分之一。最后,对该算法可能遇到的数值困难提供了一个实施方案。     

Language shift and the family: Questions from the Sri Lankan Tamil diaspora1

Fishman's Graded Intergenerational Disruption Scale (GIDS) emphasizes the family in maintaining the heritage languages of immigrant communities. This study uses interview data from Sri Lankan Tamil communities in the U.S.A., U.K., and Canada to explain how families account for the rapid loss of Tamil in the diaspora. It shows how the positive valuation of English since British colonization, the need to make up for past deprivations because of caste, religious, and gender inequality, the pressure for migrants to join the social mainstream, and the need to resolve intergenerational tensions influence the family to forego language maintenance goals. The findings encourage us to situate the family in macro‐social institutions, power, and history in order to understand the prospects for language maintenance. The article provides an inside view of the Sri Lankan Tamil migrant families to explain how they resolve the tensions of valuing cultural identity and yet disregarding heritage language proficiency.

身势语在英语教学中的运用

在英语教学过程中,为交流信息、传递感情,教师在使用语言交际的同时,还会使用多种非语言交际手段,身势语则是非语言交际中表现力最强也是最丰富的一种,并且在交际中有着口语无法替代、只可意会难以言传的魅力。在英语教学活动中,教师能否正确运用身势语,对能否营造学习英语的浓郁文化氛围,能否激活学生的积极学习兴趣,能否潜移默化地影响学生注意力,都起着潜在的重要作用。身势语是英语教学中潜在的隐性力量,关系着英语教学能否有效进行。     

Staking the claims of identity: Purism,linguistics and the media in post‐1990 Germany1

The paper examines one of the major metalinguistic debates in post‐war Germany: the debate about the influence of English on German, an issue which was raised in the 1990s in the German media and has dominated media discussions on language ever since. The analysis demonstrates that the debate is deeply embedded in current socio‐political discourses as well as in long‐term discursive traditions concerning, on the one hand, the socio‐political changes following German reunification in 1989/90, which involved a revision of the concepts of nation and nationalism, and, on the other, the genesis of the concept of nation, which is closely bound up with the history of the educated bourgeoisie and the process of standardisation as well as linguistic purism. It is argued that the debate on Anglicisms, as is the case in many other metalinguistic debates, cannot be regarded in isolation from the socio‐political environment and the context of historical usage within which it is embedded.     

论青年马克思的生态伦理观及其当代启示

马克思在《1844年经济学-哲学手稿》中阐发的生态伦理观,采用了人本学主体辩证法和社会伦理价值批判的双重思维向度和理论语境。马克思这一生态伦理观的生成与其对于劳动和人的本质的界定相关。马克思生态伦理观的价值始点与他揭示人与动物和自然关系上的异同密切相关。马克思生态伦理观又与他关于共产主义探索具有内在联系,在他看来,共产主义不仅能改变原来在私有财产条件下人与人、人与社会的关系,而且能改变人与自然的关系。由此,他还从现实物质生产（实践和工业）出发,阐释了生态伦理观的现实运作。
