2016年高三冲刺辅导(一)

静电场一、库仑定律和电场强度【例1】如图所示，带电量分别为4q 和－q 的小球A 、B 固定在水平放置的光滑绝缘细杆上，相距为d 。

若杆上套一带电小环C ，带电体A 、B 和C 均可视为点电荷。

（1）求小环C 的平衡位置。

（2）若小环C 带电量为q ，将小环拉离平衡位置一小位移x (∣x ∣<<d )后静止释放，试判断小环C 能否回到平衡位置。

（回答“能”或“不能”即可）（3）若小环C 带电量为－q ，将小环拉离平衡位置一小位移x (∣x ∣<<d )后静止释放，试证明小环C 将作简谐运动。

（提示：当α<<1时，则ααn n-≈+1)1(1）几种场源的电场：决定电场强弱的因素有两个：场源（带电量和带电体的形状）和空间位置。

这可以从不同电场的场强决定式看出—— （1）点电荷：E = k2r Q 结合点电荷的场强和叠加原理，我们可以求出任何电场的场强，如——（2）均匀带电环，垂直环面轴线上的某点P ：E =2322)(R r kQr +，其中r 和R 的意义见右图。

（3）均匀带电球壳内部：E 内= 0外部：E 外 = k2r Q，其中r 指考察点到球心的距离 如果球壳是有厚度的的（内径R 1 、外径R 2），在壳体中（R 1＜r ＜R 2）：E = 231334rR r k -πρ ，其中ρ为电荷体密度。

这个式子的物理意义可以参照万有引力定律当中（条件部分）的“剥皮法则”理解〔)(3433R r -πρ即为图中虚线以内部分的总电量…〕。

（4）无限长均匀带电直线（电荷线密度为λ）：E = rk λ2因此,无限长均匀带电直线外的电场强度大小为aE λπε∙=21,这个变换式已利用41πε=k .其中a 为P 点距直线MN 的距离,λ为电荷线密度（5）无限大均匀带电平面（电荷面密度为σ）：E = 2πk σ（6）电偶极子激发的电场真空中一对相距为l 的带等量异号电荷的点电荷系统()q q -+,，且l 远小于讨论中所涉及的距离，这样的电荷体系称为电偶极子，并且把连接两电荷的直线称为电偶极子的轴线，将电量q 与两点电荷间距l 的乘积定义为电偶极矩。

高三考前心理辅导第一篇：高三考前心理辅导一、合理营养高中生正处在青春发育期，全身各部分器官逐渐发育成熟，代谢旺盛，又活泼好动，其活动量高于任何年龄组。

这时期也是思维能力活跃、记忆力最强的时期，其学习任务十分繁重，要面临各种各样的考试。

高中时期的青少年，是长身体、长知识的关键时刻，他们的大脑皮层长期处于高度紧张之中，所以此时的营养状况必须十分重视。

在营养供给方面需与青春发育过程的生理需求相适应。

这时期如果营养供给不及时或出现营养不良，可能使青春发育期推迟一至二年。

另外，有部分高中生在幼儿、儿童时期曾因为营养不良而造成身高、体重、智力等低于标准，到了青春发育期开始只要能抓住良机，给予合理而良好的营养补给，还有可能赶上正常发育的青少年。

许多事实表明，营养对青少年不仅对体型、机能，而且对智力、情绪都产生深远的影响。

二、膳食构成高中生的膳食属于较特殊范围的一种善食。

膳食营养安排应适合于高中生生理、心理的特点。

除了保证生长发育特殊需要的营养之外，还必须考虑高中生繁重的学习任务而需要供给的特殊营养素。

在膳食质量上比小学生要高些，因此要求食堂管理人员与家长进一步了解营养知识，以利于高中生所摄入的膳食营养全面、合理而平衡。

1、三餐热能分配。

根据高中生的学习生活，一般上午要上4—5节课，脑细胞活动相当剧烈，早餐特别重要，质量数量都要有保证。

部分青少年因晨起胃口不佳或习惯性早餐摄入热能不足，上午第二节课后必须加一次课间餐（面包、糕点、牛奶、豆将之类）。

要使早餐（包括课间餐在内）的热能摄入量占全日总热能的30%，午餐占35%—40%左右，晚餐占30%—35%，高中男生肌肉细胞高速增长，加以活动量一般大于高中女生，所以热能供应要比女学生多100—300千卡左右。

一日主要食品，主食400—600克（16岁以上按600克）。

以含碳水化合物高的米、面、薯类、杂粮为主要原料。

副食品内、鱼类100—150克，鸡蛋1—2个（鸭、鹅蛋也可），大豆及豆制品适量，新鲜蔬菜500—750克，水果150—250克，牛奶、豆奶、羊奶200毫升。

高三考前心理辅导讲座有研究表明，80% 的学生在老师宣布考试时都会感到紧张，这种紧张也称为考试焦虑。

考试焦虑程度高者，表现为在考试前后精神紧张恐惧，心烦意乱，情绪低落，无精打采；肠胃不适，可能出现原因不明的腹泻、多汗、尿频、头痛、失眠、记忆力减退、注意力不集中、思维迟钝、学习效率下降等。

每年高考考生都会有“高考焦虑”的问题，产生不同程度的考试焦虑是不可避免的，但通过一些调适措施是可以减轻焦虑现象的。

考期临近，而考生的自主学习能力却不是一朝一夕能培养起来的，所以采取一些具体措施很重要。

考前的焦虑与怯场困惑着许多考生，也成为高考之前的一个热点问题。

基于此，我做一些简单的分析并提供一些对策。

一、如何缓解学业焦虑？高三学生学业焦虑主要表现为考试焦虑和学习动力不足。

（如有的学生说我害怕考试怎么办？有的说我厌恶学习怎么办？）学生考试焦虑体现在对考分的过分看重，说到底是对自己未来前途的焦虑。

之所以如此，原因有三：一是由于群体效应，将分数作为衡量学生能力的唯一指标。

二是不自觉地将获取高学历等同于自己的人生价值。

三是学生渴望自我实现（期望的）与现实学业成绩的不理想而导致的认知不协调。

只有减轻心理负担与学习负担，才能减轻学习上和精神上的压力，才能健康愉快地成长。

为了缓解和消除考试焦虑，可以尝试以下几个策略：1. 选择适合自己的（目标动机）水平，过强或过弱的动机水平都容易使自己产生失败体验而导致心理压力。

（备注1 ）2. 未来对于每一个人来说都是一个未知数，不要过多地担忧将来的事情，而应将自己的精力和时间投入到现实的生活和学习中去，为所当为。

（备注2）3. 考前作好知识准备以及应付考试的对策和心理准备，有备才能无患。

我们都有这样的体会，自己的弱课比如英语，提前几天就患得患失，反复强化这种情绪，等到了考场肯定要紧张。

所以在之前的学习中一定要做到有备无患，尽量克服自己的短板。

（备注3 ）4. 不妨采用“极限思维法”，想象你所焦虑的事件可能的最坏结果。

Although our "act" would last only for a short time, we could see quite a number of interesting things.We all stood at the far end of the studio as workmen prepared the scene, setting up trees at the edge of a winding path. Very soon, bright lights were turned on and the big movie-camera was wheeled into position. The director shouted something to the camera operator and then went to speak to the two famous actors nearby. Since it was hot in the studio, it came as a surprise to us to see one of the actors put on a heavy overcoat and start walking along the path. A big fan began blowing tiny white feathers down on him, and soon the trees were covered in "snow". Two more fans were turned on, and a "strong wind" blew through the trees. The picture looked so real that it made us feel cold.The next scene was a complete contrast (对比). The way it was filmed was quite unusual. Pictures in front taken on an island in the Pacific were shown on a glass screen (幕). An actor and actress stood of the scene so that they looked as if they w ere at the water’s edge on an island. By a simple trick like this, palm trees, sandy beaches, and blue, clear skies had been brought into the studio!Since it was our turn next, we were left wondering what scene would be prepared for us. Fora full three minutes in our lives we would be experiencing the excitement of being film "stars"!64. Who is the author?A. A cameraman.B. A film director.C. A crowd-scene actor.D. A workman for scene setting.65. What made the author feel cold?A. The heavy snowfall.B. The man-made scene.C. The low temperature.D. The film being shown.66. What would happen in the "three minutes" mentioned in the last paragraph?A. A new scene would be filmed.B. More stars would act in the film.C. The author would leave the studio.D. The next scene would be prepared.2.【2012陕西卷】 B Three Boys and a DadBrad closed the door slowly as Sue left home to visit her mother. Expecting a whole day to relax, he was thinking whether to read the newspaper or watch his favourite TV talk show on his first day off in months. “This will be like a walk in the park,” he’d told his wife. “I’ll look after the kids, and you can go visit your mom.”Things started well, but just after eight o’clock,his three little “good kids”—Mike, Randy, and Alex—came down the stairs in their night clothes and shouted “breakfast, daddy.” When food had not appeared within thirty seconds, Randy began using his spoon on Alex’s head as if it were a drum. Alex started to shout loudly in time to the beat（节拍）. Mike chanted “Where’s my toast, where’s my toast” in the background. Brad realized his newspaper would have to wait for a few seconds.Life became worse after breakfast. Mike wore Randy’s underwear on his head. Rand y locked himself in the bathroom, while Alex shouted again because he was going to wet his pants. Nobody could find clean socks, although they were before their very eyes. Someone named “Not Me” had spilled a whole glass of orange juice into the basket of clean clothes. Brad knew the talk show had already started.By ten o’clock, things were out of control. Alex was wondering why the fish in the jar refused his bread and butter. Mike was trying to show off his talent by decorating the kitchen wall with his colour pencils. Randy, thankfully, appeared to be reading quietly in the family room，but closer examination showed that he was eating apple jam straight from the bottle with his hands. Brad realised that the talk show was over and reading would be impossible.At exactly 11:17, Brad called the daycare centre (日托所）.“I suddenly have to go into work and my wife’s away. Can I bring the boys over in a few minutes?” The answer was obviously “yes” because Brad was smiling.49. When his wife left home. Brad expected to________. .A. go out for a walk in the parkB. watch TV talk show with his childrenC. enjoy his first day off workD. read the newspaper to his children50. Which of the following did Randy do?A. Drawing on the wallB. Eating apple jamC. Feeding the fish.D. Reading in a room51.Why did Brad ask the daycare centre for help?A. Because he wanted to clean up his house.B. Because he suddenly had to go to his officeC. Because he found it hard to manage his boys home.D. Because he had to take his wife back52. This text is developed ____________.A. by spaceB. by comparisonC. by processD. by time第三部分完形填空----记叙文类1.（2011·辽宁卷）This year I decided to do something to regain my good name as a kindly uncle. My 36 Tony,had never forgiven me for the dictionary I had bought him as a birthday present last year. His 37 had no reason to be thankful to me either,because the year before, I had 38 their dear son with a pot of paste(浆糊) and some funny pictures. Instead of 39 them into a book, Tony had naturally covered every wall in the house with them.

Nobody would get any 46 for weeks! I led Tony away 47 , saying that the dram was too expensive.Tony asked for permission to go off 48 and I made the most of my chance to sit down end 49 my aching feet. Fifteen minutes passed but there was still no sign of Tony. I began to get 50 and got up to look for him. I asked a young lady if she had seen a little boy in a grey suit. She looked 51 her helplessly and pointed out that there were so many 52 in grey suits. I was just going to call the police for help,when I saw a strange 53 dressed in strange orange clothes. He was wearing a false beard and had a caveman’s axe(斧子)in one hand,and a space gun in the other. It was, of course,Tony, who informed me 54 that he was the first 55 to fly into space.36.
