一、谈话导入:师:咱们班今天是谁的值日生啊?学生反馈(教师请值日的学生回答并根据班级卫生情况做出简单评价或表扬。)师:今天的值日生表现非常棒,值日工作做的很好,希望其他同学向他(她)学习。那你们想不想把我们值日时的场面画在纸上呢?今天就让我们来学习第七课《今天我值日》。(打开课件)生:学生打开课本第七课《今天我值日》。
教师:D.C.是从记号处反复,那么D.S.呢?D.S.是从头反复,到英文Fine结束。二者要区分开来,下次我们遇到再仔细讲。教师:最后我们完整的演唱一遍这首歌曲,同学们的歌唱状态准备好了吗?怎么坐的?教师:同学们演唱的真不错,从歌声里啊就能感受到同学们对祖国的热爱,对祖国未来的祝福之情。我对同学们的欣赏之情啊,犹如黄河泛滥,一发不可收拾。八、预备拓展方案:1. 这首歌曲对仗工整,相同点多,让学生模仿歌词自己编写歌词,然后演唱。2. 设计轮唱演唱形式。九、课堂小结:同学们,今天这堂课,同学们很积极,用深情地歌声表达出对伟大祖国生日的祝福,同时我们也新学了一个音乐当中的知识点:D.S.从记号处反复记号。这堂课,老师很高兴,送给在座的你们一句话:少年智,则国智;少年强,则国强;今天的课就上到这里,下课(播放音乐,学生走出教室。)
Ⅵ.活动与探究某种“15选5”的彩票的获奖号码是从1~15这15个数字小选择5个数字(可以重复),若彩民所选择的5个数字恰与获奖号码相同,即可获得特等奖.小明观察了最近100期获奖号码,发现其中竟有51期有重号(同一期获奖号码有2个或2个以上的数字相同),66期有连号(同一期获奖号码中有2个或2个以上的数字相邻).他认为获奖号码不应该有这么多重号和连号,获奖号码可能不是随机产生的,有失公允.小明的观点有道理吗?重号的概率大约是多少?利用计算器模拟实验可以估计重号的概率.[过程]两人组成一个小组,利用计算器产生1~15之间的随机数.并记录下来,每产生5个随机数为一次实验,每组做10次实验,看看有几次重号和连号.将全班的数据汇总集中起来,就可估计出1~15之间的整数中随机抽出5个数出现重号和连号的概率.

T口 F口Step 5:After listening, discuss the questions.1 What kind of person do you think Chen Liyan is?Chen Liyan is generous and honest because she returned a large sum of money to the owner.2 Did Chen return the money because she didn't need it?No. She returned the money because it was the right thing to do. Evidence for this is that she refused to accept the reward money because she felt that it had not been earned. 3 Is it common for people to do what Chen did?It depends on the culture. In some countries it is quite common to return money that has been found. In other countries, people believe "Finders are keepers!" 4 How did Wang Zheng feel about the return of his money?He must have been very happy and relieved to have gotten his money back. We know this because he thanked Chen repeatedly and even offered her a reward.5 Why did Ma Dongbao tell Wang about Chen's family?He must have had great sympathy for Chen and her daughter and wanted to help them.'We know this because he arranged help for them. 6 How did the news reporter feel about Chen's actions?The news reporter felt that it showed that money wasn't the most important thing in life. We know this because the reporter told us that this is what Chen believes. and then said, “that's a great attitude to take."

Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

一、要有率先垂范的团队领导: 领导者是团队的核心,是团队的领路人,领导者的执行力决定了这个团队的执行力。领导力就是战斗力,领导力就是执行力!对领导者而言,执行力不只是员工的义务,更是领导者的责任。身教胜于言传,要求员工做到的,领导者必须先做到,正如付老师所言:“要得到什么,就必须先付出什么!。如果领导者有”法不依、有令不行,上有政策、下有对策,那员工又怎么会听从领导的安排?如果说领导者能以身作责、率先垂范,员工上行下效怎么会执行不力?所以说,一个团队的执行力强弱与否,领导者是关键。领导者的一次率先垂范胜过对员工一百次苍白无力的说教!
①平动的物体一般可以看作质点做平动的物体,由于物体上各点的运动情况相同,可以用一个点代表整个物体的运动,在这种情况下,物体的大小、形状就无关紧要了,可以把整个物体当质点。例如:平直公路上行驶的汽车,车身上各部分的运动情况相同,当我们把汽车作为一个整体来研究它的运动的时候,就可以把汽车当作质点。当然,假如我们需要研究汽车轮胎的运动,由于轮胎上各部分运动情况不相同,那就不能把它看作质点了。要注意的是:同一物体在不同情况下有时可看质点,有时不可以看作质点,一列火车从北京开到上海,研究火车的运行的时间,可将火车看成质点,而火车过桥时,计算火车过桥的时间,不可以将火车看成质点。②有转动但转动为次要因素例如:研究地球公转时,可把地球看作质点;研究地球自转时,不能把地球看作质点。③物体的形状、大小可忽略再如:乒乓球旋转对球的运动的较大的影响,运动员在发球、击球时都要考虑,就不能把乒乓球简单看作质点。
(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)。
一、说教材《质点 参考系和坐标系》是人教版普通高中物理必修一第一章第一课的内容。本节课主要介绍了质点、参考系、坐标系的基本概念。通过本节课的学习为进一步学习后续课程起到了铺垫的作用。根据上述教材的结构和内容分析,又考虑到高一年级学生的认知结构及其心理特征,我制定了以下三维教学目标:1、知识与技能:知道质点的概念及条件;知道参考系的概念及作用;掌握坐标系的简单应用。2、过程与方法:促进学生自主学习,让学生积极参与、乐于探究、勇于实验、勤于思考,培养学生的科学探究能力。3、情感态度与价值观:通过质点 参考系和坐标系的学习,使学生了解生活与物理的关系,让学生学会用科学的思维去看待事物。根据普通高中物理课程标准,并在吃透教材的基础上,我确定了以下教学重点和难点:教学重点:质点概念的建立。只有掌握了这一点才能更加准确的理解和掌握后续教材的相关内容。
