论文部分内容阅读
随着新课程标准的实施,命题方向的变化,无疑对教师日常教学具有着直接的引领作用。下面以2004年安徽中考物理试题为例,就试题亮点部分,与读者一并赏析。一、转换试题呈现形式,侧重对学生灵活应变能力的考查中考物理试题从形式到内容上做必要的变革,是中考试题的必然发展趋势。例1 (2004年安徽第4题)我国现有的发电方式主要有火力发电、水力发电、核能发电和风力发电等。请你以其中一种(核能发电方式除外)为例,说明该发电方式的能量传递和转化过程。(例如,核能发电:核能→水和蒸汽的内能→发电机转子的机械能→
With the implementation of the new curriculum standards, the change of the propositional direction will undoubtedly have a direct leading role in the daily teaching of teachers. The following is an example of the physics test in 2004 in the examination in Anhui Province. The highlights of the questions will be read along with the readers. First, the conversion of test questions is presented in the form of a focus on the students’ flexibility in the examination of the physical examination questions from the form to the contents of the necessary changes, is the inevitable development trend of the test questions. Example 1 (2004 Anhui Question 4) The existing power generation methods in China mainly include thermal power generation, hydropower generation, nuclear power generation and wind power generation. Please take one of the examples (excluding nuclear power generation methods) as an example to illustrate the energy transfer and conversion process of this power generation method. (For example, nuclear power generation: nuclear energy → internal energy of water and steam → mechanical energy of generator rotor →
