說明:在幫Li Lei提建議的同時(shí),教育學(xué)生如何學(xué)好英語。第三課時(shí)教學(xué)目標(biāo)1. 語言目標(biāo):a) 詞匯: Original, in style, haircut, the same as.b) 語言結(jié)構(gòu):My friend wears the same clothes and has the same haircut as I do.2. 能力目標(biāo):大多數(shù)學(xué)生能夠談?wù)撟约合矚g哪種服裝,提高查找信息的能力。3. 情感目標(biāo):學(xué)會(huì)如何與朋友相處,要有自己對(duì)時(shí)尚的看法。教學(xué)重點(diǎn)掌握一些重要詞匯。教學(xué)難點(diǎn)學(xué)會(huì)談?wù)搯栴},并能提出書面建議?!艚虒W(xué)突破首先針對(duì)Erin的問題,提出個(gè)人的建議,模仿2c部分的對(duì)話展開雙人交際Pair-work;聽老師誦讀3a部分的信件,并找出LEFT OUT的問題所在;學(xué)生完成3b部分的內(nèi)容,給Left Out提出書面的建議;學(xué)以口頭形式提出自己目前存在的某個(gè)問題,講給大家聽,讓同學(xué)們給自己提出一個(gè)建議,并作筆錄;學(xué)生兩、三個(gè)人分成一組,隨意性地進(jìn)行口語交際,談?wù)揚(yáng)14的第4部分的某個(gè)問題,相互交換意見。
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 ?
"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(qǐng)做一下自我介紹。認(rèn)識(shí)一下你的新同學(xué)?!蓖ǔT谡n上老師會(huì)這樣說。你會(huì)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(duì)話。“王楠是一個(gè)很棒的乒乓球運(yùn)動(dòng)員,不是嗎?”“我希望自己能認(rèn)識(shí)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(yīng)該知道怎樣去進(jìn)行閑聊。你還應(yīng)該知道與不同的人該談?wù)撌裁礃拥脑掝}。認(rèn)真的學(xué)習(xí)這個(gè)單元吧,下次在英語課上,你會(huì)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、教材分析 1、教材內(nèi)容及所處地位綜合實(shí)踐活動(dòng)是在新一輪基礎(chǔ)教育課程改革中應(yīng)運(yùn)而生的新型課程。所謂綜合實(shí)踐活動(dòng),主要指以學(xué)生的興趣和直接經(jīng)驗(yàn)為基礎(chǔ),以與學(xué)生學(xué)習(xí)生活和社會(huì)生活密切相關(guān)的各類現(xiàn)實(shí)性、綜合性、實(shí)踐性問題為內(nèi)容,以研究性學(xué)習(xí)為主導(dǎo)學(xué)習(xí)方式,以培養(yǎng)學(xué)生的創(chuàng)新精神、實(shí)踐能力及體現(xiàn)對(duì)知識(shí)的綜合運(yùn)用為主要目的一類新型課程。具有以下特點(diǎn): 1、基于興趣與直接經(jīng)驗(yàn)。2、回歸生活世界。3、立足實(shí)踐。4、著眼創(chuàng)新。5、以研究性學(xué)習(xí)為主導(dǎo)學(xué)習(xí)方式:(1)以轉(zhuǎn)變學(xué)生的學(xué)習(xí)方式為出發(fā)點(diǎn)。(2)強(qiáng)調(diào)知識(shí)的聯(lián)系和綜合運(yùn)用。(3)注重過程。(4)強(qiáng)調(diào)開放。(5)重視師生互動(dòng)。四年級(jí)下冊(cè)綜合實(shí)踐活動(dòng)課程要培養(yǎng)學(xué)生對(duì)生活、學(xué)習(xí)的積極態(tài)度,使他們具備一定的交往合作能力、觀察分析能力、動(dòng)手操作能力;要讓他們初步掌握參與社會(huì)實(shí)踐的方法,信息資料的搜集、分析和處理問題的方法以及研究探索的方法;使學(xué)生形成合作、分享、積極進(jìn)取等良好的個(gè)性品質(zhì),成為創(chuàng)新生活的小主人。2、單元內(nèi)容分析本教材包括?方法與指導(dǎo)?和?活動(dòng)與探究?兩部分內(nèi)容, ?方法與探究? 主要是讓學(xué)生掌握如何進(jìn)行采訪,通過一系列活動(dòng),掌握采訪的準(zhǔn)備、注意事項(xiàng)、具體實(shí)施,及最后的交流總結(jié),培養(yǎng)學(xué)生交往能力。 ?活動(dòng)與探究?包括六個(gè)主題,主題一我們身邊的標(biāo)志,通過讓學(xué)生認(rèn)識(shí)標(biāo)志,體會(huì)含義。學(xué)會(huì)分類,最后學(xué)會(huì)制作標(biāo)志,循序漸進(jìn),蘊(yùn)含了創(chuàng)新、守規(guī)、審美等能力的培養(yǎng);主題二早餐與健康通過談?wù)?,調(diào)查、分析討論培養(yǎng)學(xué)生交流總結(jié)能力,樹立健康生活意識(shí);主題三,有趣的絲網(wǎng)花,通過制作培養(yǎng)學(xué)生合作、審美、動(dòng)手能力;主題四巧手做風(fēng)箏繼續(xù)對(duì)學(xué)生進(jìn)行培養(yǎng);主題五植物的扦插與嫁接,與現(xiàn)實(shí)生活聯(lián)系密切,通過活動(dòng)掌握方法,體驗(yàn)快樂,體驗(yàn)勞動(dòng)的樂趣;主題六爭(zhēng)做小小志愿者,通過了解體驗(yàn)志愿者的活動(dòng),豐富閱歷,培養(yǎng)學(xué)生的服務(wù)意識(shí),自身獲得提升與發(fā)展。教材的重點(diǎn)、難點(diǎn):重點(diǎn):學(xué)會(huì)交流,提升能力;認(rèn)識(shí)各種標(biāo)志,學(xué)會(huì)制作;學(xué)會(huì)健康的生活;通過制作絲網(wǎng)花、風(fēng)箏、植物的扦插于嫁接,學(xué)會(huì)制作,提高動(dòng)手能力,通過體驗(yàn)小小志愿者,提高服務(wù)意識(shí)。難點(diǎn):教學(xué)中讓學(xué)生親身參與、主動(dòng)實(shí)踐,在實(shí)踐中綜合運(yùn)用所學(xué)知識(shí)解決各種實(shí)際問題,提高解決實(shí)際問題的能力。學(xué)習(xí)基礎(chǔ):四年級(jí)學(xué)生已具備了一定的實(shí)踐能力,因此要逐步培養(yǎng)學(xué)生一些探究問題的方法,提高學(xué)生的動(dòng)手意識(shí),能夠從生活和學(xué)習(xí)中挖掘自己感興趣的活動(dòng)主題,能夠試著和同學(xué)展開小組合作學(xué)習(xí),在有效的活動(dòng)中不斷提高學(xué)生的動(dòng)手與創(chuàng)新的潛能。
