专注于表达的写作训练就是把写作训练的目标集中在表达能力的提高上,要表达自己实际的经历和真实的情感。既不能为文造情也不能为情造文,更不能因顾及文体要求而牺牲表达的内容和效果。专注于文体的训练作为训练的主体是错误的,但专门进行文体训练又是必要的,只要我们不把这种训练绝对化,而是通过这种训练培养学生的文体感和文体意识,就能够发挥文体训练对提高自主表达能力的作用。 相似文献

应用产业组织理论的SCP框架从市场集中度、产品差异和进入壁垒三个方面分析了中国门户网站产业的市场结构,结果显示,2009年中国门户网站产业的市场集中度很高,存在产品同质化现象,门户网站产业的进入技术壁垒比较高。因此认为,中国综合门户网站产业属于寡头垄断的市场格局。 相似文献

The emergence of Management Advice for Family Farms in West Africa is closely related to the increased integration of farmers into an open market economy. This is creating a strong demand from farmers for advisory support services, focusing on management of the farm. With the gradual withdrawal of the State from extension services delivery, a stimulating context exists for reviewing approaches and systems of support delivery facilities for producers. In response to these developments, several experiments based on the concepts of Management Advice for Family Farms are going on in West Africa. Beyond a variety of objectives and implementation procedures analysed in this paper, common features and a considerable degree of consensus on concepts emerge. Strengthening the producers' capacity for assessment, decision-making, and management of their farms is a common objective. Differences exist between procedures for delivery of advice, methods, tools used, and emphasis put on different aspects of management. All experiments stress the importance of training, enhancing group dynamics, and individual learning. They are all farmer and farm family targeted. Expression of farmers' objectives, needs, and demands is essential. Advice is based on data gathering and assessment by the farmers themselves. From mere technicians, extension workers become advisors and facilitators. In all cases, Farmers' Organisations are involved in governing the delivery services, though at different degrees. In several cases priority is given towards strengthening farmers' capacity in the management of delivery at both local and global levels. Significant improvements in farm performances have been reported. Cost sharing is generally accepted, but insufficient to cover all costs. However, to reach sustainability for farmers' driven and governed advice delivery services, innovative agricultural policies, and public finance are needed. 相似文献

用RAD7测氡仪,在深圳某高校校园内进行了土壤氡浓度的测量,选择了7个检测点,得出该高校位于龙岗区的校园内的土壤氡浓度平均值为15981Bq/m3,高于全国土壤氡浓度的平均值7300Bq/m3。还分析了该校园内土壤氡浓度与当地地质结构的相互关系。深圳为土壤氡高背景区,在住房设计过程中应采用有效的防氡手段,以保证新建住房满足室内氡气实测浓度行动水平指标。 相似文献

Abstract The establishment of the European Union, reunification of Germany, and Germany's extension of dual citizenship to immigrant minorities provided challenges to the country's understanding of itself as a nation. In negotiating these changes, debates on citizenship frequently centered on definitions of German culture. Using the concept of Leitkultur (guiding culture), conservatives argued that Germany should reject multiculturalism and stem immigration. This essay analyzes discourses on cultural policy in Germany through a contextual and textual analysis of the film Mostly Martha. In its alignment with aesthetic conventions of the art house food film, Mostly Martha participates in the debate on cultural citizenship and embodies changes in the German film industry that have moved German cinema toward increased commercialism. The film's main character, Martha, is transformed through an intercultural relationship and a trip to Italy. We argue that the film's citation of this well-known tradition of traveling south to redeem oneself and its treatment of ethnic “Otherness” engages in the Leitkultur debate and participates in the transition from national German to transnational cinema. Through the utopian treatment of Italian food, the film fetishizes cultural difference and reaffirms fixed constructs of nation and gender, thereby avoiding an explicitly politicized engagement with intercultural citizenship and identity. 相似文献
