主位推进与主动句、被动句的选择

主动句与被动句的选择是修辞学感兴趣的一个课题。根据语句内容“旧信息——新信息”的顺序理论,分析主动句和被动句主位信息的性质。在话语中主动句与被动句的使用应视上文提供的施事与受事的情形而定,如上句提供的已知信息是施事,下句宜采用主动句;上句提供的已知信息是受事,下句宜选用被动句。     

Writing to learn: an experience applied within the subject Intermediate Macroeconomics / Escribir para aprender: una aplicación para la asignatura macroeconomía intermedia

This study describes and evaluates a teaching experience that combines the use of financial press with the ‘writing to learn’ method, within the subject Intermediate Macroeconomics. The subject belongs to a field of economics which is characterized by a particularly high degree of mathematical abstraction and in which the accurate assimilation of theoretical content thus becomes essential. Thanks to the establishment of a collaboration agreement, students are offered the chance to publish press articles related to economic issues in a special supplement of El Periódico de Huelva. When comparing the academic performance of students who did or did not participate in the experience, the results appear to confirm the positive effects of using methods that promote active learning, such as the one used in this experience.

Exploring global citizenship learning and ecological Behaviour change through extracurricular activities

ABSTRACT

This research paper aims to examine the effects of extracurricular activities in building knowledge, skills and attitudes that attempt to develop ecological citizenship as a subset of global citizenship among middle school students. I focus on one extracurricular programme entitled ‘The Friends of Nature’ that was provided in a Moroccan private middle school. Adopting a qualitative research method approach, data consisted of interviews with thirty students from 7th, 8th and 9th grades and two teachers (social studies and life and earth science teacher), and were collected over the course of three months through multiple data collection tools, namely observation, student focus group discussions and teacher interviews. A series of environmental activities offered students opportunities to: identify environmental problems, promote education for sustainable development and improve their environmentally conscious behaviour, develop creative solutions, and take actions for preserving nature in their community. The data were analysed using a content analysis method. The results reveal that students demonstrated cognitive development in terms of human rights, citizenship rights and responsibilities, environmental sustainability. While the program developed attitudes of empathy, respect, solidarity, it failed to instil a sense of responsibility to act for the betterment of the world, thus being a global citizen.

活性炭的纳米材料结构和特性

活性炭是具有许多微孔的碳微晶结构的材料，因显著的活性、尤其是超常的吸附作用而有广泛的应用。目前对活性炭的研究仍停留在对普通材料的研究上面，然而笔者在对活性炭进行深入研究后的结论表明：活性炭是具有纳米结构和纳米特性的材料，从纳米技术的角度来研究活性炭可能将会有新的突破。     

汉英口译在大学英语教学中的应用

介绍在大学英语教学中以汉英口译为教学手段以提升英语能力的汉英口译训练模式。这种语言输出活动以精读教材和文化与交际知识为源语内容、集知识和技能的掌握为一体，学生同时进行汉英口译，并有电子文本给出词语核对提示，使学生在口译过程中自主纠错提高。该模式以课文和词语应用为主，有利学生扩充积极词汇，提高口语能力；且系基于自主学习的设计，故有较高的学习效率。
