第三篇:英语语言点讲解心得体会
英语语言点讲解心得体会
英语语言点讲解心得体会课文语言点的讲解一直是一个英语课堂教学的重点问题,更是一个令老师伤脑筋、让学生生畏惧的教学环节。听说课相对生动,教学活动可以更丰富;阅读课有新鲜感,要思考并完成一些任务。讲解语言点,如果处理不当就成了老师一页一页地翻ppt,学生一条一条地抄笔记,课堂气氛可想而知。
我在处理语言点的时候,有时候用ppt,有时候和学生一起走课文,还有就是让学生分组讨论然后全班展示。当然,翻ppt也不是完全就不好,毕竟信息量大,方便学生做笔记。老师也可以通过精选例句或者讲练结合等手段使课堂活跃。
赵玲老师的这节语言点讲解课有不少亮点,成功地达到教学目的。
赵老师以段落为单位讲解语言点,首先呈现中文词语,让学生在相应段落中找出英文表达,然后讲解其
中重点词汇。分段形式让学生清楚语言点在课文中的位置,以中英短语对照的方式可以加深记忆。重点词汇讲解手段变化多端。有的词汇拓展相关短语,有的呈现例句让学生总结其用法。讲练结合,通过即时练习巩固加深印象。
小型抢答竞赛活动活跃课堂气氛。在有的练习环节,赵老师设计了分数不同的问题,学生通过竞猜来获得分数。值得赞赏的是她把所得分数累积起来,由科代表课后记录,期末计入过程性评价。在例句方面,添加了时尚元素,吸引学生。比如讲preparation这个词,赵老师使用了习齤总携夫人访问俄罗斯的照片,还有哈利波特,那些年,科比受伤等。点同学回答问题用扑克牌点名。每一位同学手头都有一张扑克牌,如果老师抽到了相同的那一张,则由该同学回答问题。中奖的感觉让学生既紧张又兴奋。
从这节课可以看出赵老师的学习力不错,分段讲解、竞猜问题都是通过听别人的课学习来的,而用扑克牌点名我想应该
是从课堂教学技巧方面的书本学的。
这节课一些思考:
1.TTT(Teacher Talking Time)教师说话时间是否可以减少,比如有的例句或者练习让学生来读。教师要尽力增加学生说话时间STT(Student Talking Time)。这个问题我自己的课堂其实也要留心。
2.评价性语言还可以多样或者个性化。赵老师一般都是用good回应学生的回答,这同样是我自己要注意的。记得北师大程院长讲课的时候经常说”genius”(天才)来鼓励回答正确的同学。3.口语还需要提高,感觉带有地方音。4.激情,老师上课的激情必须要有。这个说起来谁都明白,可能因为性格或者习惯,也是难以改变的。我也常常会在课前提醒自己:兴奋一点,再兴奋一点。总而言之,这节语言点讲解的课还是成功的,科组老师认为这样更适合大多数的学生,提议以后各单元以这一方式来备语言点讲解。上公开课上出一种模式,值得表扬。

四、教学准备(teaching aids)A tape recorder, a computer and a projector
五、教学步骤(teaching procedure)Step I Listening T: As we know, a developing country builds a big dam to provide electricity for its people and control a great river.Unless something is done, a cultural relic will be list.The government must decide whether or not to save the relics.Do you know what dam and river I’m talking abut? Please look at the picture.Do you know it? Ss: Sorry, we are not familiar with it.T: OK.After listening, you are sure to know that.At first time, try to get the main idea.At
second time, try to finish the exercise and you may compares notes with your partner, at the last time, check them by yourselves.(Listen to the tape)T: Now, I’ll ask some of you to give me your answer.S1: The dam was built to stop floods on the Nile River and to give people more electricity.S2.The water in the lake behind the dam rose.53,000 people had to move and some temples were in danger.S3: False.T: You are right because it is one of the world’s largest.When completed, the Three Gorges Dam will be the world’s largest.S4: The dam would put it under water.S5: The engineers needed to find a way to move the relic to safety.S6: I chose No 3.The listening text only says that visitors are glad to see it.T: How about question No7? S7: I think it is part of history and it can tell us about how people lived in the past.S8: In my opinion, we have no right to destroy what our ancestors have created.S9: I think we can build a museum to protect our cultural relics.Step II Reading T: You know, Egypt is not the only country that has such a question.Since cultural relics are important and useful, it’s necessary for everyone to protect them.After all, they belong to the whole world.Now let’s read a passage about a common person who saves the cultural relics.Read the passage for the first time and answer why Big Feng wants to save cultural relics.(Students read the passage)T: I’d like to invite some students to answer the questions.S10: A person with “a big heart” means a person who is very kind to others.Feng Jicai shows this when he searched for his friends during the Tangshan earthquake to make sure they are safe.S11: He asks the local government to protect things of cultural interest.He works very hard to save all the old buildings of his hometown, Tianjin.S12: His first project was to save the oldest commercial street in Tianjin.S13: He saved the oldest building but the street was rebuilt.S14: He thinks more people follow what he does than what he says.T: Very good.Now how about Question No 6? S15: To put up posters announcing his latest campaign.S16: To make speeches that support Feng Jicai.S18: To go with him when he approaches the local government.Step III Talking T: Now, let’s enjoy some pictures in Beijing as well as some descriptions.T: What do you think of these hutongs in Beijing? S19: They look old and dirty, which is not fit for the heart our country.S20: They can remind us of the past, which seems warm to the Beijingers.S21: They are so close to each other, which is dangerous when there is a big fire in one house.S22: And it’s easy for the thieves to climb from one house to the other.S23: It’s not easy to drive through them, which is not good for the modern transportation.T: OK.Yes, it’s really a big problem.Beijing is developing so fast that in fact, it is a completely new city.If it is turning to a nondescript city like any other modern city in the world, do you think it a great pity? Ss: Yes, I think so.Step IV Writing
T: Speaking of the hutongs, there are so much for us to talk about.The destruction of the old is not a must indeed.Some of it should, and can be preserved.I believe there was a debate among the top leaders and city planners on whether or not to preserve them.Now, let’s try to write a letter to the city planners and tell them what you think.At first, please finish the writing task on P46, which will be helpful to you while you are writing.(Students write)T: Well, all of you did a good job.Your plans are wonderful.I hope the city planners in Beijing will accept some of your ideas and make your plans realised.Now, listen to today’s homework.Step V Homework.Make a plan to protect the Great Wall.
第五篇:高一_物理_上_牛顿第三定律_讲解
Wednesday, April 17, 2013
高一 物理 上 牛顿第三定律 讲解
一、牛顿第三定律
(一)作用力与反作用力:
1.两个物体之间的作用力总是相互的,成对出现的,相互作用的两个物体互为施力物体和受力物体。
2.将一对相互作用的力中的一个叫作用力,则另一个就叫做它的反作用力。
(二)牛顿第三定律:
1.内容:两个物体之间的作用力和反作用力总是大小相等,方向相反,作用在同一直线上。这就是牛顿第三定律。
2.理解作用力与反作用力的关系时,要注意以下几点:
(1)作用力与反作用力同时产生,同时消失,同时变化,无先后之分。
(2)作用力与反作用力总是大小相等,方向相反,作用在同一直线上(与物体的大小,形状,运动状态均无关系。)
(3)作用力与反作用力分别作用在施力物体和受力物体上,其作用效果分别体现在各自的受力物体上,所以作用力与反作用力产生的效果不能抵消。(作用力与反作用力能否求和?不能)
(4)作用力与反作用力一定是同种性质的力。(平衡力的性质呢?)
3.对于牛顿第三定律要明确
(1)定律揭示了相互作用的两个物体之间的作用力与反作用力的关系。
(2)作用力与反作用力具有“四个相同”。即大小相同,性质相同、出现、存在、消失的时间相同,作用线在同一条直线上。“三个不一样”即方向不一样。施力物体和受力物体不一样,效果不一样。
(3)相互作用力与平衡力的区别关键点是平衡力作用在同一物体上,不一定同时产生或同时消失,也不一定是同性质的力。
二、连接体问题
1.连接体:两个或两个以上相互联系的物体组成连接体。
2.整体法:当两个或两个以上有相互联系的物体相对同一参考系具有相同加速度时,可选整体为研究对象。
3.隔离法:把题目中每一物体隔离出来分别进行受力分析、列方程 4.选取研究对象的原则有两点:
(1)受力情况简单,与已知量、未知量关系密切。(2)先整体后隔离。
构成连接体的各部分之间的重要的联系纽带之一就是加速度,当两个或两个以上的物体相对同一参考系具有相同加速度时,有些题目也可采用整体与隔离相结合的方法,一般步骤用整体法或隔离法求出加速度,然后用隔离法或整体法求出未知力。
【典型例题】
例1马对车的作用力为F,车对马的作用力为T。关于F和T的说法正确的是()例2在天花板上用竖直悬绳吊一重为G的小球,小球受几个力?这些力的反作用力是哪些力?这些力的平衡力是哪些力?
例3如图所示,甲船及人总质量为m1,乙船及人的总质量为m2,已知m1=2m2,甲、乙两船上的人各拉着水平轻绳的一端对绳施力,设甲船上的人施力为F1,乙船上的人施力为

高一 物理 上 牛顿第三定律 讲解
F2。甲、乙两船原来都静止在水面上,不考虑水对船的阻力,甲船产生的加速度大小为a1,乙船产生的加速度大小为a2,则F1:F2=,a1:a2=。
例4光滑水平面上A、B两物体mA=2kg、mB=3kg,在水平外力F=20N作用下向右加速运动。求
(1)A、B两物体的加速度多大?(2)A对B的作用力多大?
例5如图所示,质量为m的物块放在倾角为的斜面上,斜面体的质量为M,斜面与物块无摩擦,地面光滑,现对斜面施一个水平推力F,要使物块相对斜面静止,力F应多大?
【例题解析】
例1马对车的作用力为F,车对马的作用力为T。关于F和T的说法正确的是()
A.F和T是一对作用力与反作用力。
B.当马与车做加速运动时,F>T。
C.当马与车做减速运动时,F D.无论做什么运动,F和T的大小总是相等的。 解析:根据牛顿第三定律F和T是一对作用力与反作用力,它们总是大小相等,方向相反,与物体运动状态无关。故AD正确。 例2在天花板上用竖直悬绳吊一重为G的小球,小球受几个力?这些力的反作用力是哪些力?这些力的平衡力是哪些力? 解析:找一个力的反作用力,就看这个力的施力物体是哪个物体,反作用力一定作用在这个物体上。 对小球的受力分析如图所示,小球受两个力:重力G、悬挂拉力F,根据牛顿第三定律可知,重力的施力物体是地球,那么G的反作用力就是物体对地球的吸引力;F的施力物体是悬绳,F的反作用力是小球对悬绳的拉力。 Product@Conda Wednesday, April 17, 2013 高一 物理 上 牛顿第三定律 讲解 小球受到的重力G和悬绳的拉力F正好是一对平衡力。答案:见解析 说明:平衡力是作用在一个物体上的力,作用力和反作用力是分别作用在两个物体上的力。平衡力可以是不同性质的力,而作用力和反作用力一定是同一性质的力。 例3如图所示,甲船及人总质量为m1,乙船及人的总质量为m2,已知m1=2m2,甲、乙两船上的人各拉着水平轻绳的一端对绳施力,设甲船上的人施力为F1,乙船上的人施力为F2。甲、乙两船原来都静止在水面上,不考虑水对船的阻力,甲船产生的加速度大小为a1,乙船产生的加速度大小为a2,则F1:F2=,a1:a2=。 解析:以绳为研究对象,它受甲船上的人所施的力F1和受乙船上的人所施的力F2。由于绳的质量为零(轻绳),故由牛顿第三定律得F1=F2,由于绳对甲船上的人所施的力F1’与F1,绳对乙船上的人所施的力F2’与F2分别为作用力与反作用力。故由牛顿第三定律可解本题。 有牛顿第三定律可知力的大小应满足关系式F1’=F1,F2’=F2所以F1’=F2/ 分别对甲、乙船应用牛顿第二定律得a1F1'm1a2F2'm2 由于m1=2m2 所以a1:a2=1:2,故F1:F2= 1:1 a1:a2=1:2 例4 光滑水平面上A、B两物体mA=2kg、mB=3kg,在水平外力F=20N作用下向右加速运动。求 (1)A、B两物体的加速度多大?(2)A对B的作用力多大? 解:设两物体加速度大小为a,A对B作用力为F1,由牛顿第三定律得B对A的作用力F2=F1。 对A受力如图 Product@Conda Wednesday, April 17, 2013 高一 物理 上 牛顿第三定律 讲解 由牛顿第二定律FF-F2=mAa 20-F2=2a ① 对B受力如图 合A =mAa 得: 由牛顿第二定律FF1=mBa F1=3a ② 由①、②联立得:a=4m/sF1=12N F=20N 而F1=12N,所以不能说力F通过物体A传递给物体B。分析:(1)(2)①+②得 F=(mA+mB)a 即:因为A、B具有相同加速度,所以可把A、B看作一个整体应用牛顿第二定律 合B =mBa 得: 思考:本题应怎样解更简单? 对AB整体受力如图 竖直方向平衡,故FN=(mA+mB)g 由牛顿第二定律F合=(mA+mB)a得: a=FmAmB20324m/s 2对B受力如图 由牛顿第二定律F 例5 如图所示,质量为m的物块放在倾角为的斜面上,斜面体的质量为M,斜面与物 Product@Conda 合B=mBa 得:F1= mBa=34=12N Wednesday, April 17, 2013 高一 物理 上 牛顿第三定律 讲解 块无摩擦,地面光滑,现对斜面施一个水平推力F,要使物块相对斜面静止,力F应多大? 解析:两物体无相对滑动,说明两物体加速度相同,方向水平。对于物块m,受两个力作用,其合力水平向左。先选取物块m为研究对象,求出它的加速度,它的加速度就是整体加速度,再根据F=(M+m)a求出推力F,步骤如下: 先选择物块为研究对象,受两个力,重力mg、支持力FN,且两力合力方向水平,如图所示,由图可得: mgtanma,agtan 再选整体为研究对象,根据牛顿第二定律F(Mm)a(Mm)gtan。答案:(Mm)gtan 说明:(1)本题的解题过程是先部分后整体,但分析思路却是先整体后部分。要求F,先选整体受力情况最简单但加速度不知,而题意却告诉m与M相对静止,实际上是告知了m的运动状态,这正是解决问题的突破口。 (2)解题的关键是抓住加速度的方向与合外力的方向一致,从而界定了m的合外力方向。 (3)试分析F>(Mm)gtan或F<(Mm)gtan时物块相对斜面体将怎样运动? 【模拟试题】 1.下列的各对力中,是相互作用力的是 [ ] A.悬绳对电灯的拉力和电灯的重力 B.电灯拉悬绳的力和悬绳拉电灯的力 C.悬绳拉天花板的力和电灯拉悬绳的力D.悬绳拉天花板的力和电灯的重力 2.在拔河比赛中,下列各因素对获胜有利的是 [ ] A.对绳的拉力大于对方 B.对地面的最大静摩擦力大于对方 C.手对绳的握力大于对方 D.质量大于对方 3.关于两个物体间作用力与反作用力的下列说法中,正确的是 [ ] A.有作用力才有反作用力,因此先有作用力后产生反作用力 B.只有两个物体处于平衡状态中,作用力与反作用才大小相等 C.作用力与反作用力只存在于相互接触的两个物体之间 D.作用力与反作用力的性质一定相同 Product@Conda Wednesday, April 17, 2013 高一 物理 上 牛顿第三定律 讲解 4.粗糙的水平地面上有一只木箱,现用一水平力拉木箱匀速前进,则 [ ] A.拉力与地面对木箱的摩擦力是一对作用力与反作用力 B.木箱对地面的压力与地面对木箱的支持力是一对平衡力 C.木箱对地面的压力与地面对木箱的支持力是一对作用力与反作用力 D.木箱对地面的压力与木箱受到的重力是一对平衡力 5.关于作用力和反作用力,下列说法中错误的是 [ ] A.我们可把物体间相互作用的任何一个力叫做作用力,另一个力叫做反作用力 B.若作用力是摩擦力,则反作用力也一定是摩擦力 C.作用力与反作用力一定是同时产生、同时消失的 D.作用力与反作用力大小相等,方向相反,作用在一条直线上,因此它们可能成为一对平衡力 6.关于反作用力在日常生活和生产技术中应用的例子,下列说法中错误的是 [ ] A.运动员在跳高时总是要用力蹬地面,他才能向上弹起 B.大炮发射炮弹时,炮身会向后倒退 C.农田灌溉用自动喷水器,当水从弯管的喷嘴里喷射出来时,弯管会自动转 D.软体动物乌贼在水中经过体侧的孔将水吸入鳃腔,然后用力把水挤出体外,乌贼就会向相反方向游去 7.如图所示,A、B两物体在水平力F的作用下共同以加速度a向右移动,则在A、B两物体间的作用力有[ ] A.1对 B.2对 C.3对 D.4对 8.如图所示,并排放在光滑水平面上的两物体的质量分别为m1和m2,且m1=2m2.在用水平推力F向右推m1时,两物体间的相互压力的大小为N1.在用大小也为F的水平推力向左推m2时,两物体间相互作用的压力大小为N2,则 [ ] A.N1=12N 2B.N1=N2 C.N1=2N2 D.N1>N2 9.如图所示,放在光滑水平桌面上的物体m2,通过穿过定滑轮的绳和吊在桌面上的物体m1相连.释放后系统加速度的大小为a1。如果取走m1,用大小等于m1所受重力的力F向下拉绳,m2的加速度为a2。则(不计滑轮摩擦及绳的质量)[ ] A.a1=a2 B.a1<a2 C.a1>a2 D.a212a1 10.如图所示,质量为ml的木块放在光滑水平面上,木块上放置一质量m2的另一木块,先后分别用水平力拉ml和m2,使两木块都能一起运动,若两次拉动木块时,两木块间的摩 Product@Conda Wednesday, April 17, 2013 高一 物理 上 牛顿第三定律 讲解 擦力分别为F1和F2,则两次拉动时,拉力之比为[ ] A.m2F1m1F2 B.F1F2 C.m1F1m2F2 D.1 11.水平桌面上放一重为20N的物块A,与地面间的动摩擦因数µ=0.4.在物块A上放一块质量为10N的物块B,(1)在拉力F作用下两物块一起沿桌面匀速向右运动,则拉力F多大?B对A的摩擦力多大?
