高中政治必修三易混易错知识点

2.必修三英语范文 篇二

一、引入用二分法求解方程

在数学学习中, 从研究已知量到认识未知量是一个变化, 承认未知量, 并通过等量关系建立方程, 又是一个很大的变化。认识方程, 学会建立方程, 是方程理论的基础, 求解方程, 是方程理论的另一部分。在传统数学教育中, 求解方程是通过运用运算规律及配方降幂、加代入消元等最基本方法求解。实际上, 用这方法只能解非常少的低次方程。比如一元二次、二元一次等等。对于高次则通过变形—变量替换为上述求解。用这种方法研究方程有很大局限性。方程理论的另一个重要发展是与函数的联系, 把方程看作函数的局部性质, 求与X轴相交的自变量的值, 这种观念可助我们思考能否通过函数性质求解方程。如连续函数在[a, b]上, 自变量a与b函数值符号相反, 则必存在x0属于[a, b]使f (x0) =0。二分法不难, 它的重要意义之一在于打开求解方程的思路。并且引入“近似”概念, 实际生活中离不开“近似”。“近似”孕育着极限的思想, 可用于确定函数值等。由此我们应该认真思考, 在数学中, 什么是重要的?重要的东西不在于难, 不在于“技巧”, 而在于它所蕴含的重要思想。

二、算法, 就是所谓构造型数学

在高中数学最基本的函数模型中, 就数学教学而言, 把算理讲清楚, 将提升我们对通性通法的理解。而把算理讲清楚, 重点是用框图来表示算理, 框图不仅是构造一张图, 还要通过它来表示算理的思维, 也就是说要把整个算法的思考过程、分析过程通过框图表示出来, 它在培养学生逻辑思维能力方面是一个非常好的载体和表现形式。通过对算法的分析, 通过对算法在高中数学教学中的功能和作用的分析, 我们开阔了眼界。

三、概率部分的设计与以往教材有很大的改变

四、单元话题阅读

Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food, get enough sleep, and exercise regularly.

Proper nutrition(营养) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”(燃料).Don’t eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白质), like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins (维他命) and minerals. However, don’t overeat. It is not helpful to be overweight.

Getting the proper amount of sleep is also important. If you don’t get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little amount of sleep may even result in a change of personality(人的个性). Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.

Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life?鄄span(寿命). Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.

If everybody, were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.

1. According to the passage, ________.

A. we should always keep fit

B. if we were healthy, we could spend our days in doing things with less sleep

C. one can eat a lot to stay in good shape

7.必修三英语范文 篇七

2001年第2版中编者是把“概率”放在第二册 (下A) 的第十章排列、组合和概率中的, 捆绑两部分内容让学生学习, 而到了2006年第2版, 编者把这两部分内容分为第十章排列、组合和二项式定理以及第十一章概率, 把概率单独成章, 虽然教学要求和目标都未改变, 不过还是可以体会编者的某种意图。到了2007年第3版的普通高中课程标准实验教科书必修3 A版中, 则把排列组合内容直接去掉, 也就是在高中必修的教材中, 不再安排学习排列组合, 而是直接学习概率。排列组合虽然在理科选修教材中出现, 但也是学习了概率之后的事情了, 文科则完全没出现。

二、教学内容变化及问题思考

新课程中的《概率》分三个小节, 随机事件的概率、古典概型、几何概型, 其中穿插了两个阅读与思考:天气变化的认识过程和概率与密码;去掉了相互独立事件同时发生的概率, 增加了几何概率。

概率内容的不断变化, 一直都让很多老师思考这样一个问题:本来先学排列组合再学概率可以说水到渠成, 很多概率内容用排列组合的思想及公式可以很快解决, 而现在直接先学概率似乎前后颠倒, 次序混乱, 因为数学讲究的是系统化, 没有排列组合作基础很多概率问题束手束脚。所以不少老师在处理这部分内容时是先补充学排列组合, 这样学生也似乎容易接受, 成绩也似乎容易提高, 这本无可厚非, 不过我们如果从新课程的角度来看编者的意图就清楚了这样变化是否合理和必要了。

三、各个知识块教学的体会

关于章头图。章头图由打炮和两颗色子的点数问题换成了飞镖、摇奖以及天气预报, 用编者的话说就是一般人都知道概率与游戏、博彩等的关系, 但本章的章头图则意在体现概率知识在科学与工农业生产等领域的应用。

关于掷硬币试验。随机事件的概率有某些问题确实可以利用排列组合很快的解决, 但是正如必修3第109页所说“获得随机事件的概率最直接的方法是实验 (观察) ”。所以编者举了抛掷硬币的试验, 让学生动手这也是新课程的思想所在, 在做中学, 让学生主动参与进来, 在知识的形成过程中学会学习。但是课堂上学生的活动应该是可控的, 又不可以把课堂变成单纯的游戏, 所以编者又安排了利用计算机模拟掷硬币试验, 解决了动手实验的不足, 那就是不能进行大量重复的试验, 利用信息技术的整合很好的解决了这个问题。这个试验使学生很容易明白一个道理:那就是随机事件发生与否虽然在单次试验中不能事先确定, 但是在大量重复试验的情况下, 它的发生呈现出一定的规律性。

而接下来的处理也可以让我们体会到编者的某种意图。新课程中让学生做了实验以后向学生展示了历史上一些掷硬币的实验结果, 其中有德·摩根、蒲丰、皮尔逊还有维尼的实验结果, 进一步向学生展示了大量重复试验中随机事件发生的规律性, 也同时教育学生科学需要坚韧不拔的毅力和持之以恒的决心, 利用数学家的故事对学生进行人生观、科学观的教育。而老教材中这个表格是直接给出的, 没有让学生进行实验, 只是直观的让学生判断, 这正是新课程理念的不同之处, 倡导自主探索、动手实践、合作交流、阅读自学等学习数学的方式。这些方式有助于发挥学生学习的主动性, 使学生的学习过程成为在教师引导下的“再创造”过程。如果教师没有体会到这层意思, 可能为了简化, 而采取了不做实验的老教材的处理思路, 那么就是典型的穿新鞋、走老路。

关于概率的意义。在老教材中, 接下来就是等可能事件的概率、互斥事件有一个发生的概率、以及相互独立事件同时发生的概率。虽然举了很多的实际例子, 但给人的感觉就像是为了解决这些问题而学习的几种解题模式, 虽然有一定的现实意义, 但是并没有给学生真正讲清楚学习概率的意义, 使人容易想起为学习而学习。在新课程中, 编者避开了直接解决的问题, 而是先让学生学习概率的意义这一节。让学生真正明白为什么学概率?比如概率的正确理解中的思考问题就很具现实意义, 还有概率在游戏、决策、天气预报中的应用不但让学生感觉很亲切, 而且更加明白概率的作用广泛, 也可以让学生领悟和提炼出极大似然法的思想, 最后还介绍了概率在生物学中的运用, 更是极大的提高了学生对学习概率的兴趣和信心, 而且可以让学生强烈的体会到数学作为基础学科的作用。这部分内容我们不应该只是完成任务型的呈现, 而是应该认真地、积极的让学生参与进去, 结合信息技术等手段, 帮学生理解和分析这部分内容, 比如投掷两枚硬币的结果是三种还是四种, 三种怎么处理, 四种又怎么处理, 换成两颗色子结果又该怎么分析, 这都是学生学习中的难点和重点, 不应该一带而过, 这样既可以培养学生对直角坐标系法的运用能力, 还可以培养学生对待问题的科学态度。

关于概率的基本性质。这部分内容则着重集合思想和概率的结合, 不但使该部分内容易于理解, 而且反过来又强化了学生对集合的理解和掌握, 符合螺旋上升的特点。当然这里还有一个重点, 那就是概率的加法公式及其简单运用, 这是每个老师都会注意到的。这里对于交事件 (积事件) 编者为了内容的完整性也作了介绍, 但没有举例, 也有老师会发现独立事件同时发生的影子, 但教材到此为此, 若是老师去补充则又是走老路去了, 增加了学生的学习难度和负担, 起不了减轻学生负担的本意和作用。

关于古典概型。这是本章的一个重点, 我们可以联想到老教材的等可能事件, 若是学过排列组合, 确实好像处理起来轻松又快捷。但是别忘了必修课程内容确定的原则是:满足未来公民的基本数学需求, 为学生进一步的学习提供必要的数学准备。选修课程内容确定的原则是:满足学生的兴趣和对未来发展的需求, 为学生进一步学习、获得较高数学修养奠定基础。把古典概型放到这里, 编者的想法应该是让学生从中掌握树状图法以及数组法等解决实际问题的基本方法, 还有这当中培养的处理实际问题的基本能力。文科生到此为止, 理科生需要进一步提高这部分数学修养则到选修课里面解决了。换句话说, 排列组合等内容是属于较高的数学要求了, 大部分学生只要能掌握基本的方法就可以了。

关于几何概型。几何概型是教材新增的内容, 它利用事件的几何度量 (长、面积、体积、角度等) 的比, 有效地解决了无限个基本事件的概率问题。我们从这里看到其实几何概型是古典概型的补充, 解决了基本事件有无限个这种古典概型不能解决的的问题, 仍属于每个结果等可能的事件, 也就是说除了要掌握概率的加法公式, 概率的各种情形中, 最常见的结果等可能的事件是最容易被学生理解和接受的一种模型, 才是学习的主要内容, 不要求扩展。

关于两种产生随机数的办法。通过模拟的方法估计随机事件发生的概率, 培养学生使用计算器、计算机的能力, 还可以让学生经历用计算机产生数据、整理数据、分析数据、画统计图的全过程, 使学生相信统计结果的真实性、随机性及规律性。此外, 利用模拟方法估计圆周率和计算不规则图形面积也使学生初步掌握了一定的实践操作技能, 极大地丰富了学生的学识水平。

关于两个阅读材料。用编者的话说就是让学生认识到自然不是神秘的, 是可以认识的, 加深对随机现象的理解, 了解人类认识随机现象的过程是逐步深入的, 了解概率这门科学有着广泛的用途。除此之外, 我们也可以借此服务于课堂教学, 比如掷硬币试验中, 学生往往会认为大量的试验统计无实际意义、费时费力, 而密码问题中的字母使用频率统计则可以使学生深刻地体会到这种工作的实际意义, 可以起到很好的示范作用。

摘要:人教社A版高中数学教材是目前应用比较广泛的教材之一, 从概率这章内容和教学要求的变化我们可以体会新课程的“新”在哪里, 如何来抓住新课程的“脉”, 本文从这两方面作粗浅的探讨和认识。

三、句式详解

1. What it was to become was a mystery until the dust began to slowly combine into a ball moving around the sun.它注定会变成什么是一个谜,直到那尘埃开始慢慢地结合成为一个绕太阳旋转的球。

句中的be to do sth为“be + 动词不定式”结构,常见用法如下:

1) 表示按计划或安排要做的事,意为“将要……”。例如:

The Prime Minister is to visit Budapest.首相将访问布达佩斯。

Their daughter is to be married soon. 他们的女儿很快就要结婚了。

2) 表示指示、要求或命令,意为“应当,必须”。

No one is to leave this building. 谁也不得离开这栋楼房。

You’re to be back by 10 o’clock. 你必须十点以前回来。

3) 表示“可能性”,相当于can或may。例如:

You are not to smoke in this room. 你不可以在这房间里抽烟。

Many new buildings are to be seen in the streets of the city. 在这座城市街道上能看到许多新建的大楼。

moving around the sun为现在分词作定语,修饰ball。现在分词作定语,通常相当于一个定语从句。表示被修饰名词是用来做什么的,单个现在分词常置于被修饰词之前,现在分词短语置于被修饰词之后。如:

a swimming pool游泳池an approaching train正在逼近的火车

Do you know the man standing at the entrance (= who is standing at the entrance)? 你认识站在门口的那个人吗?

2. The problem was that the earth became violent because it was not clear whether the solid shape was to last or not.地球变得猛烈起来,因为不清楚该固体是否会持续下去。

句中that引导的是表语从句,that引导表语从句时,本身无意义,通常不省略。例如:

My idea is that we should help her do housework every Sunday. 我的想法是:每个星期日我们应该帮助她干些家务。

be (not) clear whether…意为“(不)清楚是否……”。后可跟宾语从句。例如:

It is not clear to me whether she likes the present. 我不清楚她是否喜欢这个礼物。

It is clear that they’re doing their best. 显然他们正在尽力干。

3. But when I tried to step forward I found I was carried twice as far as on the earth and fell over.然而,当我试图向前行进时,我发现我被携带到二倍于在地球所携带的距离处,我跌倒了。

twice as far as意为“两倍于……远”。英语中倍数的表达方法一般有:1) 倍数 + 形容词 / 副词比较级 + than;2)倍数 + as + 形容词 / 副词 / (名词) + as;3) 倍数 + the +计量名词 + of。例如:

Sound travels nearly five times as fast in water as in air. 声音在水中的传播速度差不多是声音在空气中传播速度的5倍。

This room is three times larger than that one. 这个房间比那个房间大两倍。
