一是縮小頁邊距和行間距,縮小字號。正式文件一般對字號、間距有嚴格的要求,但是在非正式文件里,可適當縮小頁邊距和行間距,縮小字號??伞吧享斕欤逻B地,兩邊夠齊”,對于字號,以看清為宜。二是紙張雙面打印、復(fù)印。紙張雙面打印、復(fù)印既可以減少費用,又可以節(jié)能減排。如果全國10%的打印、復(fù)印做到這一點,那么每年可減少耗紙約5.1萬噸,節(jié)能6.4萬噸標準煤,相應(yīng)減排二氧化碳16.4萬噸。三是打印時能不加粗、不用黑體的就盡量不用,能節(jié)省墨粉或鉛粉。此外,能夠用電腦網(wǎng)絡(luò)傳遞的文件就盡量在網(wǎng)絡(luò)上傳遞,比如電子郵件、單位內(nèi)部網(wǎng)絡(luò)等,這樣下來也可以節(jié)約不少紙張。(選自《低碳校園——讓我們的學(xué)校更美好》,天津人民出版社2013年版)(學(xué)生圍繞各自任務(wù),課外搜集制作宣傳材料,時間為一周。)【設(shè)計意圖】本環(huán)節(jié)先從探討自身在低碳生活中力所能及的事情,讓學(xué)生切實認識到低碳生活就在日常的一舉一動中。然后圍繞主題分組,并保證足夠的時間,讓學(xué)生去收集整理資料,落實任務(wù),使學(xué)生能真正成為低碳的倡導(dǎo)者和踐行者。

一個不透明的袋子中裝有5個黑球和3個白球,這些球的大小、質(zhì)地完全相同,隨機從袋子中摸出4個球,則下列事件是必然事件的是( )A.摸出的4個球中至少有一個是白球B.摸出的4個球中至少有一個是黑球C.摸出的4個球中至少有兩個是黑球D.摸出的4個球中至少有兩個是白球解析:∵袋子中只有3個白球,而有5個黑球,∴摸出的4個球可能都是黑球,因此選項A是不確定事件;摸出的4個球可能都是黑球,也可以3黑1白、2黑2白、1黑3白,不管哪種情況,至少有一個球是黑球,∴選項B是必然事件;摸出的4個球可能為1黑3白,∴選項C是不確定事件;摸出的4個球可能都是黑球或1白3黑,∴選項D是不確定事件.故選B.方法總結(jié):事件類型的判斷首先要判斷該事件發(fā)生與否是不是確定的.若是確定的,再判斷其是必然發(fā)生的(必然事件),還是必然不發(fā)生的(不可能事件).若是不確定的,則該事件是不確定事件.

一、復(fù)習(xí)導(dǎo)入1、口答:最大的一位數(shù)是幾?最小的兩位數(shù)是多少?這兩個數(shù)相差多少?2、數(shù)數(shù):10個10個地數(shù),從10數(shù)到100; 1個1個地數(shù),從91數(shù)到99; 問:99加1是多少?3、導(dǎo)入:你會從100開始接著往后數(shù)嗎?今天開始我們將要學(xué)習(xí)更大的數(shù),下面請你們觀察這幅圖。二、講授新課1、出示主題圖。(1)觀察這幅圖,說一說畫面上正在發(fā)生什么事情?(2)看著畫面你想知道什么問題?引導(dǎo)學(xué)生估算畫面上的體育館大約能坐多少人?2、板書課題:1000以內(nèi)數(shù)的認識。3、教學(xué)例1。(1)數(shù)一數(shù)。每人數(shù)出10個小方塊,說說你是怎么數(shù)的?板書:一個一個地數(shù),10個一是十。

【類型一】 逆用積的乘方進行簡便運算計算:(23)2014×(32)2015.解析:將(32)2015轉(zhuǎn)化為(32)2014×32,再逆用積的乘方公式進行計算.解:原式=(23)2014×(32)2014×32=(23×32)2014×32=32.方法總結(jié):對公式an·bn=(ab)n要靈活運用,對于不符合公式的形式,要通過恒等變形轉(zhuǎn)化為公式的形式,運用此公式可進行簡便運算.【類型二】 逆用積的乘方比較數(shù)的大小試比較大?。?13×310與210×312.解:∵213×310=23×(2×3)10,210×312=32×(2×3)10,又∵23<32,∴213×310<210×312.方法總結(jié):利用積的乘方,轉(zhuǎn)化成同底數(shù)的同指數(shù)冪是解答此類問題的關(guān)鍵.三、板書設(shè)計1.積的乘方法則:積的乘方等于各因式乘方的積.即(ab)n=anbn(n是正整數(shù)).2.積的乘方的運用在本節(jié)的教學(xué)過程中教師可以采用與前面相同的方式展開教學(xué).教師在講解積的乘方公式的應(yīng)用時,再補充講解積的乘方公式的逆運算:an·bn=(ab)n,同時教師為了提高學(xué)生的運算速度和應(yīng)用能力,也可以補充講解:當n為奇數(shù)時,(-a)n=-an(n為正整數(shù));當n為偶數(shù)時,(-a)n=an(n為正整數(shù))

方法總結(jié):本題考查了冪的乘方的逆用及同底數(shù)冪的乘法,整體代入求解也比較關(guān)鍵.【類型三】 逆用冪的乘方結(jié)合方程思想求值已知221=8y+1,9y=3x-9,則代數(shù)式13x+12y的值為________.解析:由221=8y+1,9y=3x-9得221=23(y+1),32y=3x-9,則21=3(y+1),2y=x-9,解得x=21,y=6,故代數(shù)式13x+12y=7+3=10.故答案為10.方法總結(jié):根據(jù)冪的乘方的逆運算進行轉(zhuǎn)化得到x和y的方程組,求出x、y,再計算代數(shù)式.三、板書設(shè)計1.冪的乘方法則:冪的乘方,底數(shù)不變,指數(shù)相乘.即(am)n=amn(m,n都是正整數(shù)).2.冪的乘方的運用冪的乘方公式的探究方式和前節(jié)類似,因此在教學(xué)中可以利用該優(yōu)勢展開教學(xué),在探究過程中可以進一步發(fā)揮學(xué)生的主動性,盡可能地讓學(xué)生在已有知識的基礎(chǔ)上,通過自主探究,獲得冪的乘方運算的感性認識,進而理解運算法則

解析:平行線中的拐點問題,通常需過拐點作平行線.解:(1)∠AED=∠BAE+∠CDE.理由如下:過點E作EG∥AB.∵AB∥CD,∴AB∥EG∥CD,∴∠AEG=∠BAE,∠DEG=∠CDE.∵∠AED=∠AEG+∠DEG,∴∠AED=∠BAE+∠CDE;(2)同(1)可得∠AFD=∠BAF+∠CDF.∵∠BAF=2∠EAF,∠CDF=2∠EDF,∴∠BAE+∠CDE=32∠BAF+32∠CDF,∴∠AED=32∠AFD.方法總結(jié):無論平行線中的何種問題,都可轉(zhuǎn)化到基本模型中去解決,把復(fù)雜的問題分解到簡單模型中,問題便迎刃而解.三、板書設(shè)計平行線的性質(zhì):性質(zhì)1:兩條平行線被第三條直線所截,同位角相等;性質(zhì)2:兩條平行線被第三條直線所截,內(nèi)錯角相等;性質(zhì)3:兩條平行線被第三條直線所截,同旁內(nèi)角互補.平行線的性質(zhì)是幾何證明的基礎(chǔ),教學(xué)中注意基本的推理格式的書寫,培養(yǎng)學(xué)生的邏輯思維能力,鼓勵學(xué)生勇于嘗試.在課堂上,力求體現(xiàn)學(xué)生的主體地位,把課堂交給學(xué)生,讓學(xué)生在動口、動手、動腦中學(xué)數(shù)學(xué)

解析:橫軸表示時間,縱軸表示溫度.溫度最高應(yīng)找到圖象的最高點所對應(yīng)的x值,即15時,A對;溫度最低應(yīng)找到圖象的最低點所對應(yīng)的x值,即3時,B對;這天最高溫度與最低溫度的差應(yīng)讓前面的兩個y值相減,即38-22=16(℃),C錯;從圖象看出,這天0~3時,15~24時溫度在下降,D對.故選C.方法總結(jié):認真觀察圖象,弄清楚時間是自變量,溫度是因變量,然后由圖象上的點確定自變量及因變量的對應(yīng)值.三、板書設(shè)計1.用曲線型圖象表示變量間關(guān)系2.從曲線型圖象中獲取變量信息圖象法能直觀形象地表示因變量隨自變量變化的變化趨勢,可通過圖象來研究變量的某些性質(zhì),這也是數(shù)形結(jié)合的優(yōu)點,但是它也存在感性觀察不夠準確,畫面局限性大的缺點.教學(xué)中讓學(xué)生自己歸納總結(jié),回顧反思,將知識點串連起來,完成對該部分內(nèi)容的完整認識和意義建構(gòu).這對學(xué)生在實際情境中根據(jù)不同需要選擇恰當?shù)姆椒ū硎咀兞块g的關(guān)系,發(fā)展與深化思維能力是大有裨益的

解析:根據(jù)“全等三角形的對應(yīng)角相等”,可知∠EAD=∠CAB,故∠EAB=∠EAD+∠CAD+∠CAB=2∠CAB+10°=120°,即∠CAB=55°.然后在△ACB中利用三角形內(nèi)角和定理來求∠ACB的度數(shù).解:∵△ABC≌△ADE,∴∠CAB=∠EAD.∵∠EAB=120°,∠CAD=10°,∴∠EAB=∠EAD+∠CAD+∠CAB=2∠CAB+10°=120°,∴∠CAB=55°.∵∠B=∠D=25°,∴∠ACB=180°-∠CAB-∠B=180°-55°-25°=100°.方法總結(jié):本題將三角形內(nèi)角和與全等三角形的性質(zhì)綜合考查,解答問題時要將所求的角與已知角通過全等及三角形內(nèi)角之間的關(guān)系聯(lián)系起來.三、板書設(shè)計1.全等形與全等三角形的概念:能夠完全重合的圖形叫做全等形;能夠完全重合的三角形叫做全等三角形.2.全等三角形的性質(zhì):全等三角形的對應(yīng)角、對應(yīng)線段相等.首先展示全等形的圖片,激發(fā)學(xué)生興趣,從圖中總結(jié)全等形和全等三角形的概念.最后總結(jié)全等三角形的性質(zhì),通過練習(xí)來理解全等三角形的性質(zhì)并滲透符號語言推理.通過實例熟悉運用全等三角形的性質(zhì)解決一些簡單的實際問題

解析:(1)根據(jù)圖象的縱坐標,可得比賽的路程.根據(jù)圖象的橫坐標,可得比賽的結(jié)果;(2)根據(jù)乙加速后行駛的路程除以加速后的時間,可得答案.解:(1)由縱坐標看出,這次龍舟賽的全程是1000米;由橫坐標看出,乙隊先到達終點;(2)由圖象看出,相遇是在乙加速后,加速后的路程是1000-400=600(米),加速后用的時間是3.8-2.2=1.6(分鐘),乙與甲相遇時乙的速度600÷1.6=375(米/分鐘).方法總結(jié):解決雙圖象問題時,正確識別圖象,弄清楚兩圖象所代表的意義,從中挖掘有用的信息,明確實際意義.三、板書設(shè)計1.用折線型圖象表示變量間關(guān)系2.根據(jù)折線型圖象獲取信息解決問題經(jīng)歷一般規(guī)律的探索過程,培養(yǎng)學(xué)生的抽象思維能力,經(jīng)歷從實際問題中得到關(guān)系式這一過程,提升學(xué)生的數(shù)學(xué)應(yīng)用能力,使學(xué)生在探索過程中體驗成功的喜悅,樹立學(xué)習(xí)的自信心.體驗生活中數(shù)學(xué)的應(yīng)用價值,感受數(shù)學(xué)與人類生活的密切聯(lián)系,激發(fā)學(xué)生學(xué)數(shù)學(xué)、用數(shù)學(xué)的興趣

解析:(1)根據(jù)表中信息,用優(yōu)等品頻數(shù)m除以抽取的籃球數(shù)n即可;(2)根據(jù)表中數(shù)據(jù),優(yōu)等品頻率為0.94,0.95,0.93,0.94,0.94,穩(wěn)定在0.94左右,即可估計這批籃球優(yōu)等品的概率.解:(1)570600=0.95,744800=0.93,9401000=0.94,11281200=0.94,故表中依次填0.95,0.93,0.94,0.94; (2)這批籃球優(yōu)等品的概率估計值是0.94.三、板書設(shè)計1.頻率及其穩(wěn)定性:在大量重復(fù)試驗的情況下,事件的頻率會呈現(xiàn)穩(wěn)定性,即頻率會在一個常數(shù)附近擺動.隨著試驗次數(shù)的增加,擺動的幅度有越來越小的趨勢.2.用頻率估計概率:一般地,在大量重復(fù)實驗下,隨機事件A發(fā)生的頻率會穩(wěn)定到某一個常數(shù)p,于是,我們用p這個常數(shù)表示隨機事件A發(fā)生的概率,即P(A)=p.教學(xué)過程中,學(xué)生通過對比頻率與概率的區(qū)別,體會到兩者間的聯(lián)系,從而運用其解決實際生活中遇到的問題,使學(xué)生感受到數(shù)學(xué)與生活的緊密聯(lián)系

方法總結(jié):判斷軸對稱的條數(shù),仍然是根據(jù)定義進行判斷,判斷軸對稱圖形的關(guān)鍵是尋找對稱軸,注意不要遺漏.探究點二:兩個圖形成軸對稱如圖所示,哪一組的右邊圖形與左邊圖形成軸對稱?解析:根據(jù)軸對稱的意義,經(jīng)過翻折,看兩個圖形能否完全重合,若能重合,則兩個圖形成軸對稱.解:(4)(5)(6).方法總結(jié):動手操作或結(jié)合軸對稱的概念展開想象,在腦海中嘗試完成一個動態(tài)的折疊過程,從而得到結(jié)論.三、板書設(shè)計1.軸對稱圖形的定義2.對稱軸3.兩個圖形成軸對稱這節(jié)課充分利用多媒體教學(xué),給學(xué)生以直觀指導(dǎo),主動向?qū)W生質(zhì)疑,促使學(xué)生思考與發(fā)現(xiàn),形成認識,獨立獲取知識和技能.另外,借助多媒體教學(xué)給學(xué)生創(chuàng)設(shè)寬松的學(xué)習(xí)氛圍,使學(xué)生在學(xué)習(xí)中始終保持興奮、愉悅、渴求思索的心理狀態(tài),有利于學(xué)生主體性的發(fā)揮和創(chuàng)新能力的培養(yǎng)

For example: Bank, TV Station, Restaurant, Police Station, Hospital ...B) In class, show students the pictures (PowerPoint, OHP). Ask students to tell the name of the working places and the name of the jobs.Shop assistant, doctor, actor, reporter, police office, waiter, bank clerk, studentC) Do exercise 1a and 3a.2. Bingo GameAsk groups of students to make up pairs of cards with a job on one and the related workplace on the other. For example, waiter / restaurant, teacher / school, doctor / hospital. Encourage students to use both the job / workplace combinations in the book and the ones that students came up during class discussions. Be sure they have twice as many sets of cards as there are students in the group. They can make two sets of cards for a single job / workplace, if necessary. Then have each group mix up its set of cards and hand their cards out in random order. Each time a student gets a pair of cards that match, he or she can lay these cards down. The goal is to have no cards in your hand at the end.3. Task OneA) Ask students to work in pairs and ask the partner what does he / she want to be in the future.e. g. :What do you / does he / does she want to be?I want to be a.Why?Because it's (adj).B) Vocabulary: Section B, 1a4.

單元整體說明(一)單元教材分析本單元的核心話題是描述動物和表達個人喜好,以及句式why do you like…? Because…。這也是本單元的教學(xué)重點。通過本單元的學(xué)習(xí),學(xué)生應(yīng)能較流利地運用所學(xué)詞匯和句型描述動物,表達個人喜好。(二)單元知識結(jié)構(gòu)1.詞匯動物名稱 tiger, elephant, koala, dolphin, etc.詞匯描述性形容詞: smart, cute, ugly, clever, shy, etc.國家名: Australia, South Africa2.句型Why do you like koala hears? Because they are cute.Where are pandas from? They're from China.What animals do you like? I like dolphins.(三)單元整體目標1.Master the vocabulary2.Master and use: Why do you like koalas?
