Started with the discussions on the value orientation of urban water supply industry marketization,the article points out that the current urban water supply industry marketization reform is inconsistent with the goal of public water service equalization to some extent.The article also analyzes the problems emerged in urban water supply industry marketization reform and various rea-sons in view of efficiency and fairness.An efficiency and fairness oriented management model is built in this article to illustrate how the government should conciliate interests of various communities involved in the process of marketization reform of the urban water supply industry so as to actualize the coordination of efficiency and fairness.At the end,an assumption on urban water price is put forward to help achieve the public water service equalization. 展开更多

At present, with the further deepening of the integration of the world economy, the international exchanges and cooperation continue to increase, and the training mode of the talents must also be internationalized. The students should receive the cultivation of the professional knowledge, and at the same time, they must have a certain ability of the cross-cultural communication and the level of the professional English. In addition, the national medium and long-term educational reform and development plan (2010 - 2020) also proposed the strategic requirements to improve the quality of the higher education and the level of the internationalization, to promote the comprehensive development of the students. Because of this, the national big colleges and universities are carrying out the reform of the university English teaching in different degrees, and have achieved certain results. But today, in terms of the direction of the educational reform of the university English, the academic circles are still unable to reach an agreement. For example, to set the university courses in English, some scholars believe that because the English levels of the high school graduates enhance unceasingly, the courses with the language teaching as the main contents cannot meet the needs of the students, which need to be reduced or even eliminated, and should be replaced by the bilingual teaching with the liberal education as the contents. Also some scholars advocated that the orientation of the university English teaching in the future should be the ESP teaching or the academic English teaching, rather than the traditional English teaching for the humanities. 展开更多
