全班齐读第五段内容。请一位同学分析，接着让这位同学按他分析的读一遍。3、4两自然段的平缓之后，第5段作者的情感再次抬升。为了满足这种情感的张扬，作一口气连用了四个排比句式“现在是……时候”，一方面这是情感发泄的需要，另一方面这种排山倒海的语势也加强了内容的表达，极强地突出了现实为自由、平等而战的重要性。四、学会演讲我们刚才细读了课文，但读和讲是有区别的。所谓演讲，是一门语言艺术，它的主要形式是“讲”，即运用有声语言并追求言辞的表现力和声音的感染力；同时还要辅之以“演”，即运用面部表情、手势动作、身体姿态乃至一切可以理解的态势语言，使讲话“艺术化”起来，从而产生一种非凡的艺术魅力。那么，接下来就假设一下假如你是马丁·路德·金，你会怎样去讲这篇演讲辞。

思考：洗衣机脱水时转速高时容易甩干衣物，还是转速低时容易甩干衣物？(2) 制作棉花糖的原理内筒与洗衣机的脱水筒相似，里面加入白砂糖，加热使糖熔化成糖汁。内筒高速旋转，黏稠的糖汁就做离心运动，从内筒壁的小孔飞散出去，成为丝状到达温度较低的外筒，并迅速冷却凝固，变得纤细雪白，像一团团棉花。5.离心现象的防止在水平公路上行驶的汽车，转弯时所需的向心力是由车轮与路面的静摩擦力提供的。如果转弯时速度过大，所需向心力F大于最大静摩擦力Fmax，汽车将做离心运动而造成交通事故。因此，在公路弯道处，车辆行驶不允许超过规定的速度。当高速转动的砂轮或者飞轮内部分子间相互作用力不足以提供所需向心力时，离心运动就会使他们破裂，甚至酿成事故。

人教版新课标高中物理必修2太阳与行星间的引力教案2篇
【学习内容分析】在行星运动规律与万有引力定律两节内容之间安排本节内容，是为了更突出发现万有引力定律的这个科学过程。如果说上一节内容是从运动学角度描述行星运动的话，那么，本节内容是从动力学角度来研究行星运动的，研究过程是依据已有规律进行的演绎推理过程。教科书在尊重历史事实的前提下，通过一些逻辑思维的铺垫，让学生以自己现有的知识基础身于历史的背景下，经历一次“发现”万有引力的过程，因此体验物理学研究问题的方法就成为主要的教学目标。【学情分析】在学太阳对行星的引力之前，学生已经对力、重力、向心力、加速度、重力加速度、向心加速度等概念有了较好的理解，并且掌握自由落体运动和圆周运动等运动规律，能熟练运用牛顿运动定律解决动力学问题。已经完全具备深入探究和学习万有引力定律的起点能力。所以在推导太阳与行星运动规律时，教师可以要求学生自主地运用原有的知识进行推导，并要求说明每一步推理的理论依据是什么，教师仅在难点问题上做适当的点拨。

说明：“倍增法”是一种重要的物理方法，历史上库仑在研究电荷间的相互作用力时曾用过此法，但学生在此前的物理学习中可能未曾遇到类似例子，因此引导学生通过交流，领会“倍增法”的妙处，这是本节课的一个要点．可用体育锻炼中的“拉力器”来类比。（2）该方案消除摩擦力影响的方法：所用的消除方法与实验方案2一样。也可使用气垫导轨代替木板，以更好地消除摩擦影响。（3）小车速度的确定方法：①确定打出来的点大致呈现什么规律：先密后疏（变加速），再均匀分布（匀速）；②应研究小车在哪个时刻的速度：在橡皮筋刚恢复原长时小车的瞬时速度，即纸带上的点刚开始呈现均匀分布时的速度；③应如何取纸带上的点距以确定速度：由于实验器材和每次操作的分散性，尤其是橡皮筋不可能长度、粗细完全一致，使得每次改变橡皮筋的条数后，纸带上反映小车匀速运动的点数和点的位置，不一定都在事先的设定点（即用一条橡皮筋拉小车，橡皮筋刚好恢复原长时纸带上的点）处。
