张开思维翅膀，翱翔语文课堂

教学案例： 这是我听的某校“新秀杯”教学基本功大赛时的一堂高一语文课,教学内容为柳永的慢词《雨霖铃》。在本堂课的教学过程中,教师在对文章分析探究时,有这样的一个教学片断：     

回归本色——阅读的语文

如火如荼的教育改革,全面影响着语文教学。我们看到了可喜的成绩,传统的灌输式教学被否定,教师的观念在不断更新,现今又有了高效语文课堂和建构式的语文教学模式。在愈演愈烈的建构式语文教学模式的推进过程中,许多老师不禁对其效果产生了质疑。当然,更多的是我们看到了语文教学的现状。甚至有这样的流言：＂语文教与不教、     

高考现代文阅读试题的评价与反思

高考现代文阅读试题的命题,始终坚持三个有利于的原则,有利于实施中学语文课程标准,有利于推进中学全面实施素质教育,有利于高考选拔人才,具有较高的科学性.然而在优点突出的同时,也存在不足之处.     

Temperature dependence of microscopic properties in diblock copolymer films： A dissipative particle dynamics simulation

Temperature dependence of microscopic properties in diblock copolymer films has been investigated by dissipative particle dynamics simulations. Results show the relation between mean-square bond length （MSBL） and system temperature can be described as a quadratic curve. The root-mean-square radius of gyration （RMSGR） and end-end distance （RMSED） increase gradually as the temperature rises and composition fraction changes from 0.1 to 0.5, in which the effect of the former is primary. Especially, the relation between RMSGR and temperature is nearly linear in the confinement-introduced direction. Density distribution of each component in the films can be controlled and adjusted effectively by its interaction with other components and boundaries. Moreover, the changes of system temperature and composition fraction can both affect the density distributions to a certain extent.
