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,就是賓語在主從復合句當中充當賓語的一個句子,叫做賓語從句。主句的謂語動詞是及物動詞,后面如果是詞或者是短語的話,是簡單句,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,連詞一共學了三類連詞,一類連詞是that口語當中可以省略,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 ?
"Hello! Welcome to English class! Introduce yourself. Meet your new classmates." That's what the teacher says. What do you say? "Oh no!" It can be difficult talking to new people. 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? (“你好!歡迎你!請做一下自我介紹。認識一下你的新同學?!蓖ǔT谡n上老師會這樣說。你會說什么呢?“噢,不!”與陌生人談話太困難了。但是這也很有意思,并且你還能交到朋友。你該怎么做呢?閑聊。閑聊指得是禮貌的對話?!巴蹰且粋€很棒的乒乓球運動員,不是嗎?”“我希望自己能認識她,你呢?“今年的雨水很多,不是嗎?”反意疑問句是一種禮貌用語。為了使得談話成功,你應該知道怎樣去進行閑聊。你還應該知道與不同的人該談論什么樣的話題。認真的學習這個單元吧,下次在英語課上,你會發(fā)現(xiàn)與大家展開談話是一件很容易的事情,不信我們來試試。)

一.說教材我今天說課的內容是義務教育課程標準北師大版七年級下冊第四單元第二節(jié)的《用關系式表示的變量間關系》。在上節(jié)課的學習中學生已通過分析表格中的數(shù)據(jù),感受到變量之間的相依關系,并用自己的語言加以描述,初步具有了有條理的思考和表達的能力,為本節(jié)的深入學習奠定了基礎。二.說教學目標本節(jié)課根據(jù)新的教學理念和學生需要掌握的知識,確立本節(jié)課的三種教學目標:知識與能力目標:根據(jù)具體情況,能用適當?shù)暮瘮?shù)表示方法刻畫簡單實際問題中變量之間的關系,能確定簡單實際問題中函數(shù)自變量的取值范圍,并會求函數(shù)值。過程與方法目標:經(jīng)歷探索某些圖形中變量之間的關系的過程,進一步體會一個變量對另一個變量的影響,發(fā)展符號感。情感態(tài)度與價值觀目標:通過研究,學習培養(yǎng)抽象思維能力和概括能力,通過對自變量和因變量關系的表達,培養(yǎng)數(shù)學建模能力,增強應用意識。
由于任何一個一元一次不等式都能寫成ax+b>0(或<0)的形式,而此式的左邊與一次函數(shù)y=ax+b的右邊一致,所以從變化與對應的觀點考慮問題,解一元一次不等式也可以歸結為兩種認識:⑴從函數(shù)值的角度看,就是尋求使一次函數(shù)y=ax+b的值大于(或小于0)的自變量x的取值范圍。⑵從函數(shù)圖像的角度看,就是確定直線y=ax+b在x軸上(或下)方部分所有的點的橫坐標所構成的集合。教學過程中,主要從以上兩個角度探討一元一次不等式與一次函數(shù)的關系。1、“動”―――學生動口說,動腦想,動手做,親身經(jīng)歷知識發(fā)生發(fā)展的過程。2、“探”―――引導學生動手畫圖,合作討論。通過探究學習激發(fā)強烈的探索欲望。3、“樂”―――本節(jié)課的設計力求做到與學生的生活實際聯(lián)系緊一點,直觀多一點,動手多一點,使學生興趣高一點,自信心強一點,使學生樂于學習,樂于思考。4、“滲”―――在整個教學過程中,滲透用聯(lián)系的觀點看待數(shù)學問題的辨證思想。
2.送信。實物投影儀演示反饋。(1)方法說明。你是怎么想的?(2)錯誤糾正。分層校對:做完的先互相批改,然后集體先校對丁當組題,再校對一休組題。重點講評一休組題目。六、總結今天你有哪些收獲?(1)退位減法要注意什么?不要忘記退位。(2)退位減法的方法。為學生提供學習材料,讓學生通過活動聯(lián)系生活實際學習新知,讓學生感受到數(shù)學源于生活,用于生活;采用分層教學,整個學習過程都是學生在小組中合作研究、探索中完成的;然后通過多種形式的練習加以鞏固;注重學習過程的開放;通過小組合作,培養(yǎng)學生善于發(fā)表自己的觀點,會傾聽同學的意見的能力。同時也培養(yǎng)學生學會提出問題、解決問題的能力。
教學目標1、通過教學,學生懂得應用加法運算定律可以使一些分數(shù)計算簡便,會進行分數(shù)加法的簡便計算.2、培養(yǎng)學生仔細、認真的學習習慣.3、培養(yǎng)學生觀察、演繹推理的能力.教學重點整數(shù)加法運算定律在分數(shù)加法中的應用,并使一些分數(shù)加法計算簡便.教學難點整數(shù)加法運算定律在分數(shù)加法中的應用,并使一些分數(shù)加法計算簡便.教學過程設計一、復習準備(演示課件:整數(shù)加法運算定律推廣到分數(shù)加法)下載1.教師:整數(shù)加法的運算定律有哪幾個?用字母怎樣表示?板書:a+b=b+a(a+b)+c=a+(b+c)2.下面各等式應用了什么運算定律?①25+36=36+25 ②(17+28)+72=17+(28+72)③6.2+2.3=2.3+6.2 ④(0.5+1.6)+8.4=0.5+(1.6+8.4)教師:加法交換律和結合律適用于整數(shù)和小數(shù),是否也適用于分數(shù)加法呢?這節(jié)課我們就一起來研究.二、學習新課(繼續(xù)演示課件:整數(shù)加法運算定律推廣到分數(shù)加法)下載1.出示:下面每組算式的左右兩邊有什么關系?
一、教學內容:兩位數(shù)減一位數(shù)和整十數(shù)(不退位)(課本第67頁)。二、教學目標:1、知識與技能:讓學生經(jīng)歷探索兩位數(shù)減一位數(shù)和整十數(shù)(不退位)的計算方法的過程,掌握計算方法,能正確地口算。2、過程與方法:讓學生經(jīng)歷自主探索、動手操作、合作交流等方式獲得新知的過程,積累數(shù)學活動的經(jīng)驗,體會數(shù)學知識與日常生活的密切聯(lián)系,增強應用意識。3、情感態(tài)度與價值觀:進一步培養(yǎng)學生學習數(shù)學的熱情,以及積極思考、動手實踐并與同學合作學習的態(tài)度。三、教學重點:掌握兩位數(shù)減一位數(shù)和整十數(shù)(不退位)的口算方法。四、教學難點:理解算理,把握兩位數(shù)減一位數(shù)與兩位數(shù)減整十位數(shù)在計算過程中的相同點與不同點。五、教具準備:課件、題卡、等。六、教學過程:(一)、創(chuàng)設情境,提出問題。
二、互動交流,理解算法1.出示教科書第22頁的情境圖,提問:他們在干什么?你獲得了什么信息?能提出什么問題?怎樣列式?2.師:今天我們就學習一位數(shù)除三位數(shù)的計算方法。(板書課題:一位數(shù)除三位數(shù))3.師:怎樣計算238÷6呢?你能用估算的方法估計出大致結果嗎?4.學生嘗試獨立完成例3的豎式計算。師:在這道題中被除數(shù)最高位上是2個百,2個百除以6,商不夠1個百怎么辦?師:誰能說一說商3個十的3寫在商的什么位置上?為什么?教師邊板演邊說明:用除數(shù)6去乘3個十,積是18個十,表示被除數(shù)中已經(jīng)分掉的數(shù),寫在23的下面。23減18得5,表示十位上還剩5個十。師:接下來該怎么辦?(把被除數(shù)個位上的8落下來,與十位上的5合起來繼續(xù)除。)師:最后結果是多少?5.啟發(fā)學生想一想:如果一本相冊有24頁,一本相冊能插得下這些照片嗎?2本呢?
一、自覺依法納稅(二)我國稅收“取之于民,用之于民” 1、稅收的含義與基本特征 【學生活動】學生思考后回答。 【教師活動】稅收是國家為實現(xiàn)其職能,憑借其政治權力,依法無償?shù)厝〉秘斦杖氲幕拘问健?【教師活動】稅收具有強制性、無償性和固定性的基本特征。[1]強制性:不管你愿意還是不愿意,都必須交稅。[2]無償性:交了稅,沒有補償,更不會返還。[3]固定性:征稅是有標準的,不是無止境的,按標準收到一定數(shù)量即算完成納稅。 2、稅收的性質 【教師活動】展示多媒體圖片,觀察稅收性質是什么? 【學生活動】分析圖片,稅收的性質。 【教師活動】每個人都與稅收緊密地聯(lián)系在一起,我們天天享受到的公共物品,無不有賴于稅收。接受教育要有學校,看病要有醫(yī)院,出行要有道路,保障國家安全要有國防,防洪、發(fā)電要有水利工程,這些都要依靠國家的稅收來為公眾提供公共服務。 【教師活動】播放國家免費為新冠肺炎患者治療的視頻。 【教師活動】勞動人民是稅收的最終受益者,我國的稅收是取之于民、用之于民的新型稅收。
一、復習導入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、導入:你會從100開始接著往后數(shù)嗎?今天開始我們將要學習更大的數(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?引導學生估算畫面上的體育館大約能坐多少人?2、板書課題:1000以內數(shù)的認識。3、教學例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。
一、創(chuàng)設情境,導入新課 1、老師有一個好消息要告訴大家,在動物學校的旁邊開了一家超市,森林里的小動物們都去那兒購物。今天,小熊哥倆正在商店里購物呢!你想看看嗎? 2、教師出示情境圖,教師板書課題:小熊購物二、自主探究新知 1、解決第(1)個問題“小熊該付多少錢?” 1)“仔細觀察情境圖,你能發(fā)現(xiàn)哪些數(shù)學信息?”,教師總結重要數(shù)學信息?! ?2)“ 大家看小熊說的話,你能提出什么問題?” 引出“小熊該付多少錢?”這個問題?! ?3),教師巡視搜集學生出現(xiàn)的不同做法 4)展示學生作業(yè),并引導其他學生質疑“第二個算式是什么意思?”若學生中不出現(xiàn)第二個算式,教師引導學生將兩個算式合在一起?! ?5)脫式計算:根據(jù)學生列出的算式,教師結合算式指導學生進行脫式計算,規(guī)范學生的書寫格式。
1,猜一猜 師:這里有一個盒子,盒子里有一朵花,誰能猜出這朵花是什么顏色的?盒子里的花兒的顏色是確定的,為什么你們會有那么多不同的答案? ……師:好,老師給一個提示:紅色和黃色。會是什么顏色呢?師:要想準確猜出球的顏色,有一個統(tǒng)一的答案,怎么辦? 師:滿足你的愿望,第二個提示:不是紅色的。2、猜球游戲: 小朋友看,老師這里有一個白色和一個黃色的乒乓球,現(xiàn)在把它們放到盒子里,我們一起來玩一個猜一猜的游戲,好嗎? 師:我摸出其中一個,你猜猜是什么顏色的球呢?師:猜得準嗎?老師給你們一些提示吧:我摸出的不是黃球,那我摸出的是什么顏色的球?你是怎么猜的?師:那盒子里面的是什么顏色的球呢?你是怎么猜的?小朋友們很聰明,根據(jù)老師的提示能準確地判斷出球的顏色,這種方法就是我們今天要學習的簡單的推理。
