*3.3 垂径定理1.理解垂径定理和推论的内容,并会证明,利用垂径定理解决与圆有关的问题;(重点)2.利用垂径定理及其推论解决实际问题.(难点)一、情境导入 如图①某公园中央地上有一些大理石球,小明想测量球的半径,于是找了两块厚20cm 的砖塞在球的两侧(如图②所示),他量了下两砖之间的距离刚好是80cm ,聪明的你能算出大石头的半径吗?二、合作探究 探究点一:垂径定理 【类型一】 利用垂径定理求直径或弦的长度如图所示,⊙O 的直径AB 垂直弦CD于点P ,且P 是半径OB 的中点,CD =6cm ,则直径AB 的长是( )A .23cmB .32cmC .42cmD .43cm解析:∵直径AB ⊥DC ,CD =6,∴DP =3.连接OD ,∵P 是OB 的中点,设OP 为x ,则OD 为2x ,在Rt △DOP 中,根据勾股定理列方程32+x 2=(2x )2,解得x = 3.∴OD =23,∴AB =4 3.故选D.方法总结:我们常常连接半径,利用半径、弦、垂直于弦的直径造出直角三角形,然后应用勾股定理解决问题.变式训练:见《学练优》本课时练习“课堂达标训练”第3题【类型二】 垂径定理的实际应用如图,一条公路的转弯处是一段圆弧(图中的AB ︵),点O 是这段弧的圆心,C 是AB ︵上一点,OC ⊥AB ,垂足为D ,AB =300m ,CD =50m ,则这段弯路的半径是________m.解析:本题考查垂径定理,∵OC ⊥AB ,AB =300m ,∴AD =150m.设半径为R ,根据勾股定理可列方程R 2=(R -50)2+1502,解得R =250.故答案为250.方法总结:将实际问题转化为数学问题,再利用我们学过的垂径定理、勾股定理等知识进行解答.变式训练:见《学练优》本课时练习“课堂达标训练”第8题 【类型三】 垂径定理的综合应用如图,已知圆O 的直径AB 垂直于弦CD 于点E ,连接CO 并延长交AD 于点F ,且CF ⊥AD .(1)请证明:点E 是OB 的中点;(2)若AB =8,求CD 的长.解析:(1)要证明E 是OB 的中点,只要求证OE =12OB =12OC ,即∠OCE =30°;(2)在直角△OCE 中,根据勾股定理可以解得CE 的长,进而求出CD 的长.(1)证明:连接AC ,如图,∵直径AB 垂直于弦CD 于点E ,∴AC ︵=AD ︵,∴AC =AD .∵过圆心O 的直线CF ⊥AD ,∴AF =DF ,即CF 是AD 的垂直平分线,∴AC =CD ,∴AC =AD =CD ,即△ACD 是等边三角形,∴∠FCD =30°.在Rt △COE 中,OE =12OC ,∴OE =12OB ,∴点E 为OB 的中点;(2)解:在Rt △OCE 中,AB =8,∴OC =OB =12AB =4.又∵BE =OE ,∴OE =2,∴CE =OC 2-OE 2=16-4=23,∴CD =2CE =4 3.方法总结:解此类题一般要把半径、弦心距、弦的一半构建在一个直角三角形里,运用勾股定理求解.变式训练:见《学练优》本课时练习“课后巩固提升”第5题探究点二:垂径定理的推论【类型一】 利用垂径定理的推论求角的度数如图所示,⊙O 的弦AB 、AC 的夹角为50°,M 、N 分别是AB ︵、AC ︵的中点,则∠MON 的度数是( )A .100°B .110°C .120°D .130°解析:已知M 、N 分别是AB ︵、AC ︵的中点,由“平分弧的直径垂直平分弧所对的弦”得OM ⊥AB 、ON ⊥AC ,所以∠AEO =∠AFO =90°,而∠BAC =50°,由四边形内角和定理得∠MON =360°-∠AEO -∠AFO -∠BAC =360°-90°-90°-50°=130°.故选D.变式训练:见《学练优》本课时练习“课堂达标训练”第6题.【类型二】 利用垂径定理的推论求边的长度如图,点A 、B 是⊙O 上两点,AB =10cm ,点P 是⊙O 上的动点(与A 、B 不重合),连接AP 、BP ,过点O 分别作OE ⊥AP 于E ,OF ⊥PB 于F ,求EF 的长.解析:运用垂径定理先证出EF 是△ABP 的中位线,然后运用三角形中位线性质把要求的EF 与AB 建立关系,从而解决问题.解:在⊙O 中,∵OE ⊥AP ,OF ⊥PB ,∴AE =PE ,BF =PF ,∴EF 是△ABP 的中位线,∴EF =12AB =12×10=5(cm).方法总结:垂径定理虽是圆的知识,但也不是孤立的,它常和三角形等知识综合来解决问题,我们一定要把知识融会贯通,在解决问题时才能得心应手.变式训练:见《学练优》本课时练习“课后巩固提升”第2题【类型三】 动点问题如图,⊙O 的直径为10cm ,弦AB =8cm ,P 是弦AB 上的一个动点,求OP 的长度范围.解析:当点P 处于弦AB 的端点时,OP 最长,此时OP 为半径的长;当OP ⊥AB 时,OP 最短,利用垂径定理及勾股定理可求得此时OP 的长.解:作直径MN ⊥弦AB ,交AB 于点D ,由垂径定理,得AD =DB =12AB =4cm.又∵⊙O的直径为10cm ,连接OA ,∴OA =5cm.在Rt △AOD 中,由勾股定理,得OD =OA 2-AD 2=3cm.∵垂线段最短,半径最长,∴OP 的长度范围是3cm ≤OP ≤5cm.方法总结:解题的关键是明确OP 最长、最短时的情况,灵活利用垂径定理求解.容易出错的地方是不能确定最值时的情况.三、板书设计垂径定理1.垂径定理2.垂径定理的推论垂径定理是中学数学中的一个很重要的定理,由于它涉及的条件结论比较多,学生容易搞混淆,本节课采取了讲练结合、动手操作的教学方法,课前布置所有同学制作一张圆形纸片,课上利用此纸片探索、体验圆是轴对称图形,并进一步利用圆的轴对称性探究垂径定理,环环相扣、逐层深入,激发学生的学习兴趣,收到了很好的教学效果.。
Teaching steps:
Step 1 : Warmer 1、Greetings: T: Ok,Let’s begin our class. Good morning, boys and girls!
Ss: Good morning, Ms Ren! T: How are you today? Ss: I’m fine, thank you. And how are you? T: I’m fine, thanks. Let’s say a chant and do some actions , ok? Ss: OK! T : Are you ready? Ss: Yes!
Make a cake, Make a cake, put it in the pan. Make a cake, Make me a cake, as fast as you can.(动作指导:边唱边拍手 ) (设计意图:师生一起边说边做动作的过程调动了学生学习英语的积极性,活跃了课堂气氛。)
Step 2. Presentation (一)巩固旧知,引入新句型 1、 T:The cake is very nice ,I’m hungry, Are you hungry?
Ss:Yes 2、T:(老师出示食物图片)Do you want some cake/rice/milk/dumplings/vegetables ?(抽生 回答,复习以前学习的食物单词)
3、老师边问 Do you want some soup?边出示图片。教授新单词soup 并且用这种方法教授新单词sweets、bread ,biscuit 、fruit.
4、Say a Chant:
Soup, soup , have some soup . Bread , bread , have some bread. ______, _____, have some ______. ______, _____, have some ______. ______, _____, have some ______. (设计意图:教师运用本课的新单词将chant 补充完整,给学生做出示范后,要求学生四人小组)
5. T: Boys and girls, let’s play a game – Lucky animals, ok?
Ss: OK! T: Look ,lost of delicious food. Do you like them? Ss: Yes. T: Do you want to have them? Ss: Yes. T: You can use “Can I have some„?” to tell us what you want to have. Then you can choose one of animal . There is a piece of paper behind the card. You can get the answer from it. e.g. S1: Can I have some biscuits? S1 chooses a dog. Sa: Yes, you can. (设计意图 : 利用游戏“Lucky animals”向学生渗透句型Can I have
some ... ...?) (二)创设情景,引入并呈现课文
T : Look, boys and girls ! Today is December,21th.Can you guess whose birthday is today? Is it Daming’s birthday? Is
it Sam’s birthday? Let’s listen to The tape and answer my question.
(1) Listen and answer
老师播放课文录音,学生根据老师提出的问题边听录音边找答案,看谁又快又准。
Questions:①Can you guess whose birthday is today? ②What does she want to eat? ③How does she ask for food? (2)跟录音朗读课文, listen and answer my questions. ① Today is Amy’s birthday. ② She wants to eat sweets\soup\bread. ③ Can I have some sweets\soup\bread? (设计意图:通过回答问题学习课文的里的句子,培养学生自主学习能力。) (3)跟录音朗读课文,讲解、操练句型,
Can I have some ________?
Yes, you can. Sorry ,you can’t. 在学习难点句子时,老师利用肢体语言帮助学生理解句意,Turn on the light .(做开灯的动作) I can’t see . It’s very dark.(双手伸出做摸的动作 ),师生共同边做动作边说这些句子。
Step 3: Practise
1、Game: Share food. 开展“分享食物”游戏,规则是在课本P34 activity 3 呈现的食物图片中,选出自己最喜欢的两个事物并悄悄地圈出来,让其他同学猜,老师用“吊小人”的规则负责记录学生猜的次数,如果小人被最终吊起,同学还没有猜中他选择的食物,并得到“Sorry ,you can’t.”的委婉拒绝,老师则宣布游戏失败。
要求:学生询问食物时需用到本课学的句型:“Can I have some…?” 如果猜对了,讲台上的同学就要用“Yes, you can.Here you are.”分享他的食物。
(设计意图:让学生在这一活动中参与积极,纷纷举手到讲台前面展示,在趣味十足的猜测和回答中运用了本课所学的句型,孩子们的表现欲被点燃了。)
2、Draw and guess.学生画自己喜欢的食物,小组内成员猜食物。 3、模仿,分角色朗读课文。 (设计意图:多种形式的操练是帮助小学生将知识转化为言语技能的重要手段,也是提高小学英语教学质量的关键一步。操练内容由低到高,由浅入深,让学生在层层操练中循序渐进,最后达到熟练掌握。) Step 4 : Consolidation(巩固活动) 用 的语调唱出本节所学的重点句型: Can I have some soup? Can I have some soup? Yes,you can. Yes,you can. Can I have some sweets? Can I have some sweets? Sorry,you can’t.Sorry,you can’t. 可以布置学生课后配上其他曲调唱唱试试。 Step 5. Homework 1). Find out your mother or your father’s birthday And make something for them. 2). Listen and read to your parents Step 6. 板书设计 Module 9 Happy Birthday! Unit 1 Can I have some sweets?
Can I have some (图片略)?
Yes, you can. Sorry, you can’t.
Biscuits and sweets Bread ,soup,cake are very very nice. are also very nice. Can I have some? Can I have some? Yes, you can. Sorry ,you can't.
1)T: Look, we are in the restaurant now. Miss geng is a waitress. Who wants to be customers?
Ss: Me. T: Welcome! Do you want some water? S1: Yes, please. S2: No, thank you. T: Do you want some bread? S2: Yes,please. T: Ok, you want some water. And you want some bread. S1: Can I have some soup? T: Yes, you can. 2)T: Suppose today is your birthday. You will hold a big party with your friends.
一、热身/复习 Free talk后,出示chant “Noodles and rice.”学生跟着老师打着节奏说唱,通过韵句既活跃了课堂气氛,又引出与本课学习内容相关的食物。问学生:Do you like noodles? Do you like rice?生回答后接着导入下一环节的教学:Today I take some other food for you. Look! 二、呈现课文新单词 从事先准备好的袋子中一样一样地拿出实物,展示并学习课文中新的食物单词:fruit/bread/ soup/sweets/ biscuits,在认读单词时,可采取学生试读、教师教读、小老师领读、高高低低等方式学习,全部出示后,再看卡片读、看实物说单词、看口型猜单词等方式综合记忆。 (目的是让学生认读单词时形式不单调,既有趣味又能读好读准确。) 三、呈现课文内容 T:These food are very very nice, Do you want some? Ss: Yes. T: Today we will learn how to ask for food politely. Open your books, Module 9 unit1.
