During the Listening & Speaking & Talking and Reading and Thinking section, the influence in examples has been shown. Thus, use the Present Perfect Tense is appropriate. However, in order to show the justice or weaken the doer of the behavior/action, it’s better to use the Present Perfect Passive Voice than the Present Perfect Tense. Besides, having learned to use the Present Perfect Passive Voice, students can beautify their language in their writing. 1. Learn the structure of the Present Perfect Passive Voice and its functions. 2. Learn to change the sentences with the Present Perfect Passive Voice into the sentences with the Present Perfect Passive Voice. 3.

新人教版高中英语必修2Unit 3 The Internet-Listening &Speaking＆Talking教案一
Listening and Speaking introduces the topic of “ask about online habits”. Many middle school students have been surfing the Internet for many years, but what they do with the Internet and how much time they spend every day may not be very clear to themselves, nor to other students. This section allows students to investigate their peers' Internet use, which is conducive to their mutual understanding and understanding of the Internet. It can also help them reflect on their own online behavior, learn from other people's good online habits, and get rid of their bad online behavior.The listening text of this section is an investigation interview. The investigators interview specific groups with the same questions to obtain information, so as to understand their views, practices or attitudes on this issue. There are two specific questions: “how much time do you spend online every day? What do you usually do online?”. The answers of the three respondents provide rich and different information, and achieve the purpose of the investigators. The oral discourse structure of survey interviews generally includes greeting and explaining the purpose of the interview, presenting the interview questions and the respondents' answers. Listening and Talking introduces the theme of “choosing the right application ". Listening text is a conversation between Laura and Xiao Bo. In this part of listening, “oink”； “piggy bank” may cause the students' hearing comprehension limitation. Oink refers to sound word and pig's sound. So, add some oink to my piggy bank is often used to describe "making a little money".1. Guide students to understand the content of listening texts in terms of listening for definitions.2. Cultivate students' ability to define words and understand an investigation interview.

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。

人教版新课标高中物理必修1探究加速度与力、质量的关系教案2篇
1．加速度与力的关系：实验的基本思路是保持物体的质量不变，测量物体在不同的力的作用下的加速度，分析加速度与力的关系。有了实验的基本思路，接下去我们就要准备实验器材，以及为记录实验数据而设计一个表格。为了更直观地判断加速度与力的数量关系，我们以 为纵坐标、 为横坐标建立坐标系，根据各组数据在坐标系中描点。如果这些点在一条过原点的直线上，说明 与 成正比，如果不是这样，则需进一步分析。2．加速度与质量的关系：实验的基本思路是保持物体所受力不变，测量不同质量的物体在该力作用下的加速度，分析加速度与质量的关系。有了实验的基本思路，接下去我们就要准备实验器材，以及为记录实验数据而设计一个表格。为了更直观地判断加速度与质量的数量关系，我们以 为纵坐标、 为横坐标建立坐标系，根据各组数据在坐标系中描点，根据拟合的曲线形状，初步判断 与 的关系是反比例函数。再把 图像改画为 图像，如果是一条过原点的斜直线，说明自己的猜测是否正确。
人教版新课标高中物理必修1伽利略对自由落体运动的研究教案2篇
猜想：既然物体下落过程中的运动情况与物体质量无关，那么为什么在现实生活中，不同物体的落体运动，下落快慢不同呢？我们能否猜想是由于空气阻力的作用造成的呢？如果没有空气阻力将会怎样呢？学生讨论后回答.三、猜想与假说伽利略认为，自由落体是一种最简单的变速运动.他设想，最简单的变速运动的速度应该是均匀变化的.但是，速度的变化怎样才算均匀呢?他考虑了两种可能：一种是速度的变化对时间来说是均匀的，即经过相等的时间，速度的变化相等；另一种是速度的变化对位移来说是均匀的，即经过相等的位移，速度的变化相等.伽利略假设第一种方式最简单，并把这种运动叫做匀变速运动.四、实验验证实验验证是检验理论正确与否的唯一标准.任何结论和猜想都必须经过实验验证，否则不成理论.猜想或假说只有通过验证才会成为理论.所谓实验验证就是任何人，在理论条件下去操作都能到得实验结果，它具有任意性，但不是无条件的，实验是在一定条件下的验证，而与实际有区别.

三、制定实验方案的两个问题：1．怎样测量（或比较）物体的加速度：引导学生思考、讨论并交流。学生可能会提出下面的一些方案：方法一：测出初速度为零的匀加速直线运动的物体在 时间内的位移 ，则 ；方法二：在运动的物体上安装一条打点计时器的纸带，根据纸带上打出的点来测量加速度；方法三：测出两个初速度为零的匀加速运动的物体在相同的时间内发生的位移 、 ，则 ；方法四：测出两个初速度为零的匀加速运动的物体在相同的位移内所用的时间 、 ，则 ；2．怎样提供并测量物体所受的恒力：教师提出：现实中，除了在真空中抛出或落下的物体（仅受重力）外，仅受一个力的物体几乎是不存在的。然而，一个单独的力作用效果与跟它大小、方向都相同的合力的作用效果是相同的，因此，实验中力 的含义指物体所受的合力。以在水平轨道上用绳牵引小车加速运动为例，小车受到四个力的作用，即重力、支持力、绳的拉力和轨道对小车的摩擦力（当物体运动的速度比较小时，我们可以忽略空气的阻力）。

四、速度和速率学生阅读教材第18页相应部分的知识点，让学生总结．生：速度既有大小，又有方向，是矢量，速度的大小叫速率，教师引导学生看教材第18页图1．3—2．观察汽车的速度计，讨论后说出你从表盘上获取的有用信息。生：汽车的速率．指针指在相应数字的瞬间，就表示汽车在那一瞬时的速率是那个值．生：还可以从表盘上直接读出公里里程．师：日常生活中的“速度”有时指速度，也有时指速率，要看实际的物理情景。[讨论与交流]甲、乙两位同学用不同的时间围绕操场跑了一圈，都回到了出发点，他们的平均速度相同吗?怎样比较他们运动的快慢?学生讨论，体验平均速度的缺陷，引入平均速率。生1：位移都是零，平均速度等于位移跟发生这段位移所用时间的比值，所以他们的平均速度都是零。生2：即使一位同学站在原地不跑，他的平均速度也是零啊，可我们运动会上不是这样比快慢的，如果这样，那多不公平啊?

人教版新课标高中物理必修2探究弹性势能的表达式教案2篇
“做功的过程就是能量转化过程”，这是本章教学中的一条主线。对于一种势能，就一定对应于相应的力做功。类比研究重力势能是从分析重力做功入手的，研究弹簧的弹性势能则应从弹簧的弹力做功入手。然而弹簧的弹力是一个变力，如何研究变力做功是本节的一个难点，也是重点。首先，要引导学生通过类比重力做功和重力势能的关系得出弹簧的弹力做功和弹簧的弹性势能的关系。其次，通过合理的猜想与假设得出弹簧的弹力做功与哪些物理量有关。最后，类比匀变速直线运动求位移的方法，进行知识迁移，利用微元法的思想得到弹簧弹力做功的表达式，逐步把微分和积分的思想渗透到学生的思维中。本节课通过游戏引入课题，通过生活中拉弓射箭、撑杆跳高和弹跳蛙等玩具以及各种弹簧等实例来创设情景，提出问题。给学生感性认识，引起学生的好奇心；让学生对弹簧弹力做功的影响因素进行猜想和假设，提出合理的推测，激发学生的探索心理，构思实验，为定性探究打下基础。然后，引导学生通过类比重力做功与重力势能的关系得出弹簧弹性势能与弹簧弹力做功的关系。

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。
