内容提示1.本单元主要内容是学会used to结构。Used to +动词原形表示过去经常、以前常常,只用于过去式中,用来表示现在已不存在的习惯或状态。例如:They used to play football together.他们过去常在一起蹋足球。(现在不在一起踢了)2.used to的疑问形式和否定形式为Did you use to…?和I didn’t use to… 也可以用Used you to…?和I used not to…但现在多使用前者。例如:Did you used to swim in the river? 你过去常在河里游泳吗?I didn’t use to play the piano. 我以前并不经常弹钢琴。教学目标一、学习目标(Language Goal) 1.学会陈述自己过去常做的事情。2.学会陈述自己过去的爱好等。3.能够表达自己现在和过去在外表、性格、娱乐等方面的变化。4.能够表达朋友、家人等现在和过去的变化。二、语言结构(Language Structures) 1.I used to be short when I was young. 我年轻时个子很矮。 2. —Did you use to have straight hair? 你过去是直发吗?—Yes, I did. 是的。 3. —Did you use to play the piano? 你过去弹钢琴吗?—No, I didn’t. 不,我不弹。 4.I used to be afraid of dark. 我过去害怕黑暗。 5.I’m terrified of the snakes. 我害怕蛇。

一、导入新课我们已经学过鲁迅先生的不少文章,学过他的小说,看他用无数生动的形象表达他在时代里的“呐喊”与“彷徨”;学过他的散文,与他一同在失落中“朝花夕拾”,安静地回忆过往。今天,我们将学习鲁迅先生的一篇杂文,看他是如何作为民族斗士,将手中的笔,变成抨击敌人的枪。二、教学新课目标导学一:学习驳论,理清思路1.初读课文,找出对方的错误观点,并说说作者是怎样引出这一观点的。明确:对方的错误观点是“中国人失掉自信力了”。开篇以似乎确凿的事实为据,用一句话指出了三个阶段中“中国人”表现出来的三种不同的态度:盲目骄傲,夜郎自大;盲目崇拜,借助外援;今不如昔,祈求鬼神。即由自夸到崇洋,到自欺欺人、虚无渺茫的态度变化。因此有人“慨叹”:“中国人失掉自信力了。”这是论敌的论点。
教学过程:一、边欣赏音乐边介绍巴赫及其求学之路。通过背景音乐和文字说明,使同学们掌握一些有关西方音乐的文化。二、初步了解小步舞曲。通过文字叙述,简单了解小步舞曲。三、讲述《小步舞曲》曲的音乐内容。对节奏、速度、力度、节拍以及体裁进行了解。四、结合谱例分段学习《小步舞曲》。1、学习乐曲A’段。说明:依据乐曲创作背景,合理创设“舞会”情景,从而有效激发学生学习兴趣,用舞蹈表现手段演绎此乐段,发展了学生的舞蹈表演能力,享受到美的愉悦。2、学习乐曲B段。说明:利用形象、直观的图式辅助以及一系列贴近学生思维逻辑的问答讨论,激发学生的思考,帮助学生准确把握乐段情绪,并能用指挥、伴奏等方式表现该乐段。3、完整欣赏《小步舞曲》。说明:学生在完整欣赏乐曲时能够巩固乐曲主题的记忆,并且听辨、感受乐曲两个不同主题情绪,培养学生独立的音乐感受和见解。五、视频欣赏。说明:通过视屏欣赏,使同学们以一个更直观的郊区去理解和学习作品,并使同学对作品有更深刻的记忆。引起学生共鸣,领悟音乐的美感,愉悦身心,获取乐趣,从而激起学习的情趣。
【教学目标】(一)教学知识点能够利用描点法作出函数 的图象,并根据图象认识和理解二次函数 的性质;比较两者的异同.(二)能力训练要求:经历探索二次函数 图象的作法和性质的过程,获得利用图象研究函数性质的经验.(三)情感态度与价值观:通过学生自己的探索活动,达到对抛物线自身特点的认识和对二次函数性质的理解. 【重、难点】重点 :会画y=ax2的图象,理解其性质。难点:描点法画y=ax2的图象,体会数与形的相互联系。 【导学流程】 一、自主预习(用时15分钟)1.创设教学情境我们在教学了正比例函数、一次函数、反比例函数的定义后,都借助图像研究了它们的性质.而上节课我们所学的二次函数的图象是什么呢?本节课我们将从最简单的二次函数y=x2入手去研究
解析:先利用正比例函数解析式确定A点坐标,然后观察函数图象得到,当1<x<2时,直线y=2x都在直线y=kx+b的上方,于是可得到不等式0<kx+b<2x的解集.把A(x,2)代入y=2x得2x=2,解得x=1,则A点坐标为(1,2),∴当x>1时,2x>kx+b.∵函数y=kx+b(k≠0)的图象经过点B(2,0),即不等式0<kx+b<2x的解集为1<x<2.故选C.方法总结:本题考查了一次函数与一元一次不等式的关系:从函数的角度看,就是寻求使一次函数y=ax+b的值大于(或小于)0的自变量x的取值范围;从函数图象的角度看,就是确定直线y=kx+b在y轴上(或下)方部分所有的点的横坐标所构成的集合.三、板书设计1.通过函数图象确定一元一次不等式的解集2.一元一次不等式与一次函数的关系本课时主要是掌握运用一次函数的图象解一元一次不等式,在教学过程中采用讲练结合的方法,让学生充分参与到教学活动中,主动、自主的学习.
解析:(1)根据题设条件,求出等量关系,列一元一次方程即可求解;(2)根据题设中的不等关系列出相应的不等式,通过求解不等式确定最值,求最值时要注意自变量的取值范围.解:设购进A种树苗x棵,则购进B种树苗(17-x)棵,(1)根据题意得80x+60(17-x)=1220,解得x=10,所以17-x=17-10=7,答:购进A种树苗10棵,B种树苗7棵;(2)由题意得17-x172,所需费用为80x+60(17-x)=20x+1020(元),费用最省需x取最小整数9,此时17-x=17-9=8,此时所需费用为20×9+1020=1200(元).答:购买9棵A种树苗,8棵B种树苗的费用最省,此方案所需费用1200元.三、板书设计一元一次不等式与一次函数关系的实际应用分类讨论思想、数形结合思想本课时结合生活中的实例组织学生进行探索,在探索的过程中渗透分类讨论的思想方法,培养学生分析、解决问题的能力,从新课到练习都充分调动了学生的思考能力,为后面的学习打下基础.
解析:(1)已知抛物线解析式y=ax2+bx+0.9,选定抛物线上两点E(1,1.4),B(6,0.9),把坐标代入解析式即可得出a、b的值,继而得出抛物线解析式;(2)求出y=1.575时,对应的x的两个值,从而可确定t的取值范围.解:(1)由题意得点E的坐标为(1,1.4),点B的坐标为(6,0.9),代入y=ax2+bx+0.9,得a+b+0.9=1.4,36a+6b+0.9=0.9,解得a=-0.1,b=0.6.故所求的抛物线的解析式为y=-0.1x2+0.6x+0.9;(2)157.5cm=1.575m,当y=1.575时,-0.1x2+0.6x+0.9=1.575,解得x1=32,x2=92,则t的取值范围为32<t<92.方法总结:解答本题的关键是注意审题,将实际问题转化为求函数问题,培养自己利用数学知识解答实际问题的能力.三、板书设计二次函数y=ax2+bx+c的图象与性质1.二次函数y=ax2+bx+c的图象与性质2.二次函数y=ax2+bx+c的应用
1.使学生掌握用描点法画出函数y=ax2+bx+c的图象。2.使学生掌握用图象或通过配方确定抛物线的开口方向、对称轴和顶点坐标。让学生经历探索二次函数y=ax2+bx+c的图象的开口方向、对称轴和顶点坐标以及性质的过程,理解二次函数y=ax2+bx+c的性质。用描点法画出二次函数y=ax2+bx+c的图象和通过配方确定抛物线的对称轴、顶点坐标理解二次函数y=ax2+bx+c(a≠0)的性质以及它的对称轴(顶点坐标分别是x=-b2a、(-b2a,4ac-b24a)一、提出问题1.你能说出函数y=-4(x-2)2+1图象的开口方向、对称轴和顶点坐标吗?(函数y=-4(x-2)2+1图象的开口向下,对称轴为直线x=2,顶点坐标是(2,1)。2.函数y=-4(x-2)2+1图象与函数y=-4x2的图象有什么关系?(函数y=-4(x-2)2+1的图象可以看成是将函数y=-4x2的图象向右平移2个单位再向上平移1个单位得到的)
(3)设点A的坐标为(m,0),则点B的坐标为(12-m,0),点C的坐标为(12-m,-16m2+2m),点D的坐标为(m,-16m2+2m).∴“支撑架”总长AD+DC+CB=(-16m2+2m)+(12-2m)+(-16m2+2m)=-13m2+2m+12=-13(m-3)2+15.∵此二次函数的图象开口向下,∴当m=3米时,“支撑架”的总长有最大值为15米.方法总结:解决本题的关键是根据图形特点选取一个合适的参数表示它们,得出关系式后运用函数性质来解.三、板书设计二次函数y=a(x-h)2+k的图象与性质1.二次函数y=a(x-h)2+k的图象与性质2.二次函数y=a(x-h)2+k的图象与y=ax2的图象的关系3.二次函数y=a(x-h)2+k的应用要使课堂真正成为学生展示自我的舞台,还学生课堂学习的主体地位,教师要把激发学生学习热情和提高学生学习能力放在教学首位,为学生提供展示自己聪明才智的机会,使课堂真正成为学生展示自我的舞台.充分利用合作交流的形式,能使教师发现学生分析问题、解决问题的独到见解以及思维的误区,以便指导今后的教学.
