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 ?
人教版新目標初中英語八年級下冊It’s a nice day, isn’t it教案2篇
"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。“王楠是一個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)現與大家展開談話是一件很容易的事情，不信我們來試試。)

小學數學人教版三年級上冊《數字編碼》說課稿
一、說教材（一）教材分析這部分教材是在新課標理念下新增加的一節(jié)實踐活動課，重要是向學生滲透數字編碼的數學思想。本節(jié)課是通過日常生活中的一些事例，如：學號、門牌號、身份證號等使學生進一步體會數字編碼在日常生活中的應用，并通過實踐活動進行簡單的數字編碼，培養(yǎng)學生的抽象、概括能力。（二）學生分析學生在第一學段已經對數字編碼有了簡單的了解，如：運動員的號牌、車牌號、郵編、門牌號等。學生也簡單的知道數不僅可以用來表示數量和順序，還可以用來編碼。這節(jié)課就是在學生的生活經驗和已有知識的基礎上，進一步體會數字編碼在日常生活中的應用，并通過實踐活動進行簡單的數字編碼，培養(yǎng)學生的抽象、概括能力。（三）教學目標根據教材的特點和課標要求，從學生的實際出發(fā)，我確定了一下教學目標： 1、經歷嘗試編寫本學校獨一無二學號的過程，使學生體會數字編碼在生活中的應用，探索數字編碼的簡單方法。 2．初步培養(yǎng)學生抽象概括的能力，提高應用意識和實踐活動能力。 3．體會數字應用的廣泛性，提高學習數學的興趣和積極性。
小學數學人教版一年級上冊《加減混合》說課稿
大家好，今天我說課的內容是人教版義務教育課程標準實驗教科書數學一年級上冊第五單元中的《加減混合》。一、教材分析（一）教學內容及重點難點與上一節(jié)課學習的連加、連減相同，加減混合也是由兩個計算步驟構成的一個連續(xù)的口算過程，但不同的是對于一年級學生來說既要記住第一步計算結果，又要在第二步計算時應對跟第一步不同的運算方法有一定的難度。所以掌握加減混合運算過程是本課的重點和難點之一。 另一方面，教材有意地呈現了對比性很強的兩組情境圖幫助學生學習，情境圖既有現實性和趣味性，又能直觀地展示加減混合算式的計算過程和算理，充分體現數學來源于生活，又巧妙地利用生活經驗來理解數學知識。但是教材是第一次出現組合型的情境圖，學生對圖中原來物體的個數很難理解，所以如何指導學生學會看這種組合型的情境圖也是本節(jié)課教學的另一重難點。
小學數學人教版四年級上冊《口算除法》說課稿
一、說教材的地位和作用。??本節(jié)內容是“除數是兩位數除法的口算除法”，也就是有關整十、整百數除以整十數的口算除法，由于口算在日常生活中有著廣泛的應用，是進行筆算和估算的基礎，同時，也為學生今后繼續(xù)學習除數是三位數的除法打基礎的，口算和估算技能的掌握程度直接影響筆算除法的學習，所以這部分知識占據著非常重要的地位。四年級學生已經具備了一定的計算基礎，已完全掌握表內除法與一位數乘整十、整百、整千數的乘法口算，所以學生對“除數是兩位數，商是整十、整百、整千數”的除法口算應該不是很難，重要的是讓學生理解它的算理，并運用算理進行快速的口算，還有就是要聯系生活實際，培養(yǎng)學生的估算意識，讓教學為生活服務。
小學數學人教版一年級上冊《左右》說課稿
一、說教材1、教學內容《左右》是義務教育課程標準實驗教科書數學一年級上冊第二單元“位置”第二課時的內容。2、教學內容的地位與作用《左右》是前后上下的延續(xù)性學習。但認識左右比認識前后上下要困難一些。“左右”的含義及其相對性要具有更強的空間觀念。通過學習，可以發(fā)展學生的空間觀念，為以后認識立體圖形建立空間立體感打好基礎，提高解決實際問題的能力，使學生初步感受數學與生活的聯系。3、教學目標(1)認識“左右”的位置關系，體會其相對性。(2)在認識“左右”的過程中，培養(yǎng)初步的判斷能力，能夠運用“左右”描述物體的位置，并解決簡單的實際問題。(3)通過生動有趣的數學活動，使學生體會到學習數學的樂趣，增強對數學學習的興趣。4、教學重點：認識“左右”的位置關系5、教學難點：體會“左右”的相對性
小學數學人教版一年級上冊《比多少》說課稿
尊敬的各位領導、老師：大家好！我說課的內容是人教版一年級上冊第6頁至第8頁準備課的第二課時《比多少》。我將從教學背景分析、教學目標、教學流程、教學設計特色幾方面談談我對這節(jié)課的設想。一、教學背景分析（一）教材分析本課時通過讓學生開展簡單的比較活動，經歷并體驗比較的過程，初步學習比較的方法，為以后的數學學習做思想方法上的準備。另外這一課，也是后面認知各數大小以及學習后面數學知識的基礎。書中是以小豬蓋房子的故事開始，激發(fā)學生學習興趣，通過“在情境圖中找一找，比一比”，讓學生自己尋找可比的對象，選擇比較的標準來“比”，給學生較大的自由發(fā)揮空間，體現“以人為本”、“以發(fā)展為宗旨”的素質教育新理念和目標。（二）學情分析 “比多少”這部分內容，學生在學習它之前，已經學習了數數，有了一定的數學基礎，所以學習比多少時學生上路還是比較快的。學生一般在入學前對它們都有了初步的認識，通過對各種物體的感知，已經積累了感性經驗。但是在判斷時學生往往是憑直覺，不一定會用一一對應的方法來比較兩組物體的多少或者用數一數的辦法來比較多少?；谝陨系牧私?，我進行了這樣的思考。
小學數學人教版一年級上冊《9加幾》說課稿
各位評委、老師，大家好，我今天說課的課題是九年義務教育人教版一年級數學上冊第八單元第一課時《9加幾》。一．說教材： 《9加幾》是一年級上冊第八單元的教學內容。本節(jié)內容是學生建立“湊十法”計算概念的初次接觸，也為以后計算的正確率和提高運算速度打下牢固的基礎。教材在編寫上注重從學生的生活經驗出發(fā)，讓學生在生動具體的生活環(huán)境中學習數學。本單元的內容編排體現了三個特點：一是從情境中提出數學問題，二是呈現多種計算方法，三是讓學生動手操作、觀察、理解算理、掌握算法。注重培養(yǎng)學生初步應用數學的意識和解決問題的能力。本節(jié)課的目標為： （一）知識技能:理解“湊十法”，初步掌握9加幾的進位加法的思維過程，并能正確的計算9加幾。
