人教版新课标高中物理必修1质点参考系和坐标系教案2篇
（创设实例：多媒体播放视频刘翔的110m栏。）1．提出问题：怎样定量（准确）人描述车或刘翔所在的位置？2．提示：你的描述必须能反映物体（或人）的运动特点（直线）、运动方向、各点之间的距离等因素。3．总结：①为了定量地描述物体的位置及位置的变化，需要在参考系上建立适当的坐标系。坐标系是在参考系的基础上抽象出来的概念，是抽象化的参考系。为了定量地描述物体的位置及位置的变化需要在参考系上建立适当的坐标系，如果物体在一维空间运动，即沿一条直线运动，只需建立直线坐标系，就能准确表达物体的位置；如果物体在二维空间运动，即在同一平面运动，就需要建立平面直角坐标系来描述物体的位置；当物体在三维空间运动时，则需要建立三维坐标系。①一维坐标：描述物体在一条直线上运动，即物体做一维运动时，可以以这条直线为x轴，在直线上规定原点、正方向和单位长度，建立直线坐标系。如图1-1-1所示，若某一物体运动到A点，此时它的位置坐标XA＝3m，若它运动到B点，则此时它的坐标XB＝-2m（“-”表示沿X轴负方向）。

人教版新目标初中英语八年级下册It’s a nice day, isn’t it教案2篇
"Hello! Welcome to English class! Introduce yourself. Meet your new classmates." That's what the teacher says. What do you say? "Oh no!" It can be difficult talking to new people. But it can be fun, and you can make friends. How do you do it? Make small talk. Small talk is polite conversation. "Wang Nan is a great pingpang player, isn't she?" "I'd love to meet her, wouldn't you?" "It's been raining a lot, hasn't it?" Tag questions are a form of polite speech. To make small talk successfully, you should know how to make them. You should also know what topics to talk about. Try to learn this unit carefully. The next time you're in English class, you'll find out. Making small talk's easy, isn't it? (“你好！欢迎你！请做一下自我介绍。认识一下你的新同学。”通常在课上老师会这样说。你会说什么呢？“噢，不！”与陌生人谈话太困难了。但是这也很有意思，并且你还能交到朋友。你该怎么做呢？闲聊。闲聊指得是礼貌的对话。“王楠是一个很棒的乒乓球运动员，不是吗？”“我希望自己能认识她，你呢？“今年的雨水很多，不是吗？”反意疑问句是一种礼貌用语。为了使得谈话成功，你应该知道怎样去进行闲聊。你还应该知道与不同的人该谈论什么样的话题。认真的学习这个单元吧，下次在英语课上，你会发现与大家展开谈话是一件很容易的事情，不信我们来试试。)

区分宾语从句、定于从句和状语从句宾语从句和状语从句，都叫做主从复合句。宾语从句主要是中考必考的，是初中阶段必掌握的从句，宾语从句主要是掌握三要素，所谓宾语从句，就是宾语在主从复合句当中充当宾语的一个句子，叫做宾语从句。主句的谓语动词是及物动词，后面如果是词或者是短语的话，是简单句，如果是句子的话，肯定是宾语从句。I know that he good at English.就是宾语从句，三要素，一要素是要注意连词，连词一共学了三类连词，一类连词是that口语当中可以省略，就像刚才说的那一句，I hear he is good at English.还有疑问代词、疑问副词，how where when，疑问代词、疑问副词。还有一类连词weather是否的意思，不是状语从句当中的如果，这一定要和如果区分开，这是是否。I don't know if he interested at English。宾语从句要注意if是连词。第二要素是语序，要用陈述举语序。比如说你家有几口人，我们都说How many people are there in you family?但是这是简单句，一旦说成宾语从句，你可以告诉我你家有几口人吗？Could you tell me how many people there are in you family ?

人教版新课标高中物理必修2研究平抛运动教案3篇
（给出仪器后先让学生思考如何设计实验、安装仪器、设计实验步骤，而后教师总结）实验步骤如下：①安装调整斜槽 ：用图钉把白纸钉在竖直板上，在木板的左上角固定斜槽。②调整木板 ：用悬挂在槽口的重锤线把木板调整到竖直方向，并使木板平面与小球下落的竖直面平行，然后把重锤线方向记录到钉在木板上的白纸上，固定木板，使在重复实验的过程中，木板与斜槽的相对位置保持不变。③确定坐标原点：把小球放在槽口处，用铅笔记下小球在槽口时球心在木板上的水平投影点O，O即为坐标原点。④描绘运动轨迹 ：用铅笔的笔尖轻轻地靠在木板的平面上，不断调整笔尖的位置，使从斜槽上滚下的小球正好碰到笔尖，然后就用铅笔在该处白纸上点上一个黑点，这就记下了小球球心所对应的位置。保证小球每次从槽上开始滚下的位置都相同，用同样的方法可找出小球平抛轨迹上的一系列位置。取下白纸，描绘小球做平抛运动的轨迹。
