北師大初中九年級(jí)數(shù)學(xué)下冊(cè)圓教案
解析：首先求得圓的半徑長(zhǎng)，然后求得P、Q、R到Q′的距離，即可作出判斷．解：⊙O′的半徑是r＝ 12＋12＝2，PO′＝2＞2，則點(diǎn)P在⊙O′的外部；QO′＝1＜2，則點(diǎn)Q在⊙O′的內(nèi)部；RO′＝（2－1）2＋（2－1）2＝2＝圓的半徑，故點(diǎn)R在圓上．方法總結(jié)：注意運(yùn)用平面內(nèi)兩點(diǎn)之間的距離公式，設(shè)平面內(nèi)任意兩點(diǎn)的坐標(biāo)分別為A(x1，y1)，B(x2，y2)，則AB＝（x1－x2）2＋（y1－y2）2.【類型四】 點(diǎn)與圓的位置關(guān)系的實(shí)際應(yīng)用如圖，城市A的正北方向50千米的B處，有一無線電信號(hào)發(fā)射塔．已知，該發(fā)射塔發(fā)射的無線電信號(hào)的有效半徑為100千米，AC是一條直達(dá)C城的公路，從A城發(fā)往C城的客車車速為60千米/時(shí)．(1)當(dāng)客車從A城出發(fā)開往C城時(shí)，某人立即打開無線電收音機(jī)，客車行駛了0.5小時(shí)的時(shí)候，接收信號(hào)最強(qiáng)．此時(shí)，客車到發(fā)射塔的距離是多少千米(離發(fā)射塔越近，信號(hào)越強(qiáng))?(2)客車從A城到C城共行駛2小時(shí)，請(qǐng)你判斷到C城后還能接收到信號(hào)嗎？請(qǐng)說明理由．
北師大初中九年級(jí)數(shù)學(xué)下冊(cè)圓的對(duì)稱性教案
我們知道圓是一個(gè)旋轉(zhuǎn)對(duì)稱圖形，無論繞圓心旋轉(zhuǎn)多少度，它都能與自身重合，對(duì)稱中心即為其圓心．將圖中的扇形AOB(陰影部分)繞點(diǎn)O逆時(shí)針旋轉(zhuǎn)某個(gè)角度，畫出旋轉(zhuǎn)之后的圖形，比較前后兩個(gè)圖形，你能發(fā)現(xiàn)什么？二、合作探究探究點(diǎn)：圓心角、弧、弦之間的關(guān)系【類型一】 利用圓心角、弧、弦之間的關(guān)系證明線段相等如圖，M為⊙O上一點(diǎn)，MA︵＝MB︵，MD⊥OA于D，ME⊥OB于E，求證：MD＝ME.解析：連接MO，根據(jù)等弧對(duì)等圓心角，則∠MOD＝∠MOE，再由角平分線的性質(zhì)，得出MD＝ME.證明：連接MO，∵ MA︵＝MB︵，∴∠MOD＝∠MOE，又∵M(jìn)D⊥OA于D，ME⊥OB于E，∴MD＝ME.方法總結(jié)：圓心角、弧、弦之間相等關(guān)系的定理可以用來證明線段相等．本題考查了等弧對(duì)等圓心角，以及角平分線的性質(zhì)．

區(qū)分賓語從句、定于從句和狀語從句賓語從句和狀語從句，都叫做主從復(fù)合句。賓語從句主要是中考必考的，是初中階段必掌握的從句，賓語從句主要是掌握三要素，所謂賓語從句，就是賓語在主從復(fù)合句當(dāng)中充當(dāng)賓語的一個(gè)句子，叫做賓語從句。主句的謂語動(dòng)詞是及物動(dòng)詞，后面如果是詞或者是短語的話，是簡(jiǎn)單句，如果是句子的話，肯定是賓語從句。I know that he good at English.就是賓語從句，三要素，一要素是要注意連詞，連詞一共學(xué)了三類連詞，一類連詞是that口語當(dāng)中可以省略，就像剛才說的那一句，I hear he is good at English.還有疑問代詞、疑問副詞，how where when，疑問代詞、疑問副詞。還有一類連詞weather是否的意思，不是狀語從句當(dāng)中的如果，這一定要和如果區(qū)分開，這是是否。I don't know if he interested at English。賓語從句要注意if是連詞。第二要素是語序，要用陳述舉語序。比如說你家有幾口人，我們都說How many people are there in you family?但是這是簡(jiǎn)單句，一旦說成賓語從句，你可以告訴我你家有幾口人嗎？Could you tell me how many people there are in you family ?

But it can be fun, and you can make friends. How do you do it? Make small talk. Small talk is polite conversation. "Wang Nan is a great pingpang player, isn't she?" "I'd love to meet her, wouldn't you?" "It's been raining a lot, hasn't it?" Tag questions are a form of polite speech. To make small talk successfully, you should know how to make them. You should also know what topics to talk about. Try to learn this unit carefully. The next time you're in English class, you'll find out. Making small talk's easy, isn't it?
