从维熙与索尔仁尼琴分别是中苏"大墙文学"的代表作家,他们的作品以上个世纪的劳改营为背景,描写了一批因政治运动而被劳改之人的命运。两位作家特别关注了劳改犯们在环境极其恶劣的劳改营里人性的善良之处,中国作家从维熙笔下的人物都有着"圣人"式的善良——似真金般,不论身处何境都能以中国传统道德意义上的"善"去帮助他人;而索尔仁尼琴笔下的人物则心怀基督式的怜悯之善,充满着生命的情怀,活出自己的原则与立场。  相似文献

The purpose of the paper is to present the reasons students at the Faculty of Education in Maribor, Slovenija, chose pedagogy for their study direction, and therefore becoming a teacher. A total 237 second‐year students of the academic year 2003/04 were included in the research. Of the five groups of reasons for choosing this program (altruistic, material, self‐realization and alternative, and reasons arising from aspiration stereotype), students most often asserted self‐realization, including: teaching provides a useful public function for the whole society; as a teacher, I can be an example to children and young people; this profession will give me a chance for professional development during my whole career; and teaching will enable me to use all my abilities (and talents—for example, music, verbal, dancing, etc.) Important differences were found to exist between students of different disciplines.  相似文献

会计是一种艺术,具有艺术的自然与纯真、独创与齐放等特点;会计教学理应向学生传到"真善美"。会计教学真善美的基础在于教师是否围绕教学内容,从真善美的角度上深入研究、领悟和传播教材内外的真善美因素,以及学生对真善美的辨识、把握与追求等。要实施和实现会计教学的真善美,就必须在会计教学中以艺术的手段和方法让真善美得以切实感知、得到有效组织和积极导向。  相似文献
