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

教學(xué)目標(biāo)1.使學(xué)生通過(guò)“稱(chēng)一稱(chēng)”的實(shí)踐活動(dòng)，親自感受1克和1千克的實(shí)際重量。2.通過(guò)實(shí)踐活動(dòng)使學(xué)生加深質(zhì)量單位的理解，讓學(xué)生深刻體會(huì)到質(zhì)量單位與實(shí)際生活是緊密聯(lián)系的，在實(shí)際生活中是非常有用的。3.培養(yǎng)學(xué)生的動(dòng)手能力及創(chuàng)新意識(shí)。4.培養(yǎng)學(xué)生與他人的合作意識(shí)和分工合作的精神。重、難點(diǎn)與關(guān)鍵1.進(jìn)一步了解克和千克的質(zhì)量單位概念。能夠用老師提供的稱(chēng)，來(lái)稱(chēng)量物體質(zhì)量。2.鞏固對(duì)質(zhì)量單位實(shí)際概念是認(rèn)識(shí)。教具準(zhǔn)備天平，盤(pán)秤，適量的生活用品，如水果，蔬菜等。教學(xué)過(guò)程一、創(chuàng)設(shè)情境同學(xué)們這節(jié)課老師帶你們?nèi)コ泄湟还?，想去嗎？（出示課本第85頁(yè)情境圖）在超市里你看到了什么？指名回答。（餅干110克、豆油5千克、6個(gè)蘋(píng)果1千克……）這些都表示什么意思呢？指名回答。教師說(shuō)明表示物品有多重可以用克和千克作單位。那么在日常生活中有什么地方用到克與千克呢？舉例說(shuō)明。

2.采用比較簡(jiǎn)便的方法，師生合作完成“數(shù)據(jù)的收集與整理（強(qiáng)調(diào)數(shù)據(jù)的準(zhǔn)確性），學(xué)生獨(dú)立完成“表格的填寫(xiě)”。3.小組內(nèi)討論完成“表格的分析”。4.全班進(jìn)行反饋。（意在培養(yǎng)獨(dú)立收集、整理數(shù)據(jù)的能力，核對(duì)數(shù)據(jù)的準(zhǔn)確性，并且擴(kuò)大提問(wèn)題的參與面，讓學(xué)生也能啟動(dòng)智慧、享受快樂(lè)；及時(shí)反饋信息，調(diào)整教學(xué)目標(biāo)）四、全課總結(jié)1.通過(guò)今天的學(xué)習(xí)，同學(xué)們有哪些收獲？2.應(yīng)用延伸。（課本第112頁(yè)練習(xí)二十二第1題）五、布置作業(yè)教后反思統(tǒng)計(jì)是日常生產(chǎn)生活中常用和實(shí)用的工具，因此統(tǒng)計(jì)也是小學(xué)生必備的能力之一。但是統(tǒng)計(jì)的教學(xué)較為枯燥無(wú)味，教師往往會(huì)輕視統(tǒng)計(jì)的教學(xué)，忽略學(xué)生能力方面的培養(yǎng)。在教學(xué)統(tǒng)計(jì)時(shí)，老師要激發(fā)學(xué)生學(xué)習(xí)統(tǒng)計(jì)的興趣，創(chuàng)造各種情景，加強(qiáng)學(xué)生統(tǒng)計(jì)中的動(dòng)手實(shí)踐操作訓(xùn)練，同時(shí)在實(shí)際生活中加以運(yùn)用，并逐步加大難度和密度，同時(shí)也需要知道，統(tǒng)計(jì)教學(xué)不要過(guò)分地浮夸，多給予學(xué)生統(tǒng)計(jì)的意義，使其明確學(xué)習(xí)的目的。
