Listening and Speaking introduces the topic of “Take part in a youth project”. The listening text is an interview about "sharing views on historical sites". Through listening to a dialogue between Chinese and foreign students on the way to the Confucius Temple, students can understand their views on the Confucius Temple, Confucius, Confucius' descendants and Confucius' educational thoughts, so as to realize and think about the profound influence of Confucius and his thoughts on Chinese historical tradition. At the same time, the dialogue naturally integrates English idioms and mentions Shakespeare, the British playwright, so as to provide language materials and context for students to understand English idioms and related cultural allusions, as well as to compare Chinese and foreign cultures, which is helpful for students to understand and express the language such as history, tradition, culture and custom significant impact.Text analysis: listening text is a dialogue between a British student and a Chinese student when he goes to the Confucius Temple. When William, a British student, visited the Confucius Temple, he asked Xiao Kong, a Chinese student, for directions. Xiao Kong was just going to the Confucius Temple to meet with the members of the research group, so they went together and exchanged their views on the Confucius Temple, Confucius, Confucius' descendants and Confucius' educational thoughts. From the perspective of foreign tourists, this paper describes their thoughts on Confucius, the great son of Confucius, who had a profound impact on Chinese history and cultural tradition, and his education.Listening and Talking introduces a visit to a historic tourist destination.

人教A版高中数学必修二简单随机抽样教学设计
知识探究（一）：普查与抽查像人口普查这样，对每一个调查调查对象都进行调查的方法，称为全面调查（又称普查）。 在一个调查中，我们把调查对象的全体称为总体，组成总体的每一个调查对象称为个体。为了强调调查目的，也可以把调查对象的某些指标的全体作为总体，每一个调查对象的相应指标作为个体。问题二：除了普查，还有其他的调查方法吗？由于人口普查需要花费巨大的财力、物力，因而不宜经常进行。为了及时掌握全国人口变动状况，我国每年还会进行一次人口变动情况的调查，根据抽取的居民情况来推断总体的人口变动情况。像这样，根据一定目的，从总体中抽取一部分个体进行调查，并以此为依据对总体的情况作出估计和判断的方法，称为抽样调查（或称抽查）。我们把从总体中抽取的那部分个体称为样本，样本中包含的个体数称为样本量。

人教版高中历史必修3宋明理学教案2篇
二、程朱理学：1、宋代“理学”的产生：（1）含义：所谓“理学”，就是用“理学”一词来指明当时两宋时期所呈现出来的儒学。广义的理学，泛指以讨论天道问题为中心的整个哲学思潮，包括各种不同的学派；狭义的理学，专指程颢、程颐、朱熹为代表的，以“理”为最高范畴的学说，称为“程朱理学”。理学是北宋政治、社会、经济发展的理论表现，是中国古代哲学长期发展的结果，是批判佛、道学说的产物。他们把“理”或“天理”视作哲学的最高范畴，认为理无所不在，不生不灭，不仅是世界的本原，也是社会生活的最高准则。在穷理方法上，程颢“主静”，强调“正心诚意”；程颐“主敬”，强调“格物致知”。在人性论上，二程主张“去人欲，存天理”，并深入阐释这一观点使之更加系统化。二程学说的出现，标志着宋代“理学”思想体系的正式形成。【合作探究】宋代“理学”兴起的社会条件：
人教版新课标高中物理必修1摩擦力教案2篇
l．知识与技能：（1）知道摩擦力产生的条件。（2）能在简单问题中，根据物体的运动状态，判断静摩擦力的有无、大小和方向；知道存在着最大静摩擦力。（3）掌握动磨擦因数，会在具体问题中计算滑动磨擦力，掌握判定摩擦力方向的方法。（4）知道影响到摩擦因数的因素。2．过程与方法：通过观察演示实验，概括出摩擦力产生的条件及摩擦力的特点，培养学生的观察、概括能力。通过静摩擦力与滑动摩擦力的区别对比，培养学生分析综合能力。3．情感态度价值观：在分析物体所受摩擦力时，突出主要矛盾，忽略次要因素及无关因素，总结出摩擦力产生的条件和规律。二、重点、难点分析1．本节课的内容分滑动摩擦力和静摩擦力两部分。重点是摩擦力产生的条件、特性和规律，通过演示实验得出关系f=μN。2．难点是学生有初中的知识，往往误认为压力N的大小总是跟滑动物体所受的重力相等，因此必须指出只有当两物体的接触面垂直，物体在水平拉力作用下，沿水平面滑动时，压力N的大小才跟物体所受的重力相等。
人教版新课标高中物理必修2平抛运动教案2篇
（五）平抛运动规律的应用例1：一架老式飞机在高出海面45m的高处，以80m/s的速度水平飞行，为了使飞机上投下的炸弹落在停在海面上的敌船，应该在与轰炸目标的水平距离为多远的地方投弹?不计空气阻力。分析：对于这道题我们可以从以下几个方面来考虑：(1)从水平飞行的飞机上投下的炸弹，做什么运动?为什么?(2)炸弹的这种运动可分解为哪两个什么样的分运动?3)要想使炸弹投到指定的目标处，你认为炸弹落地前在水平方向通过的距离与投弹时飞机离目标的水平距离之间有什么关系?拓展：1、式飞机在高出海面45m的高处，以80m/s的速度水平飞行，尾追一艘以15m/s逃逸的敌船，为了使飞机上投下的炸弹正好击中敌船，应该在与轰炸目标的水平距离为多远的地方投弹?不计空气阻力。2、在一次摩托车跨越壕沟的表演中，摩托车从壕沟的一侧以速度v＝40m/s沿水平方向向另一侧，壕沟两侧的高度及宽度如图所示，摩托车可看做质点，不计空气阻力。（1）判断摩托车能否跨越壕沟？请计算说明（2）若能跨过，求落地速度？
