【教材分析】高考聽力材料的選用非常重視語(yǔ)言真實(shí)性和交際性的原則,語(yǔ)言材料一般來源于實(shí)際生活,對(duì)話的內(nèi)容大都取材于日常生活,即衣、食、住、行、工作、學(xué)習(xí)、天氣、生活環(huán)境等話題,可分為校園、公共場(chǎng)所、家庭等方面,如: shopping, finding the way, doing one’s homework, seeing a doctor, making a phone call, weather report, asking for different kinds of information等。新教材的特點(diǎn)就是利用生活中真實(shí)文本,只是降低難度,讓學(xué)生注重語(yǔ)言的應(yīng)用,將是我們高考把握方向的重要因素?!窘虒W(xué)目標(biāo)與核心素養(yǎng)】學(xué)習(xí)能力目標(biāo):在聽力當(dāng)中,學(xué)生應(yīng)該有效規(guī)劃學(xué)習(xí)方法,選擇恰當(dāng)?shù)牟呗耘c方法。這節(jié)課的訓(xùn)練目標(biāo)是讓學(xué)生有正確的預(yù)測(cè)和抓住問題的關(guān)鍵信息,從而用心去聽來找尋關(guān)鍵信息。根據(jù)生活中實(shí)際情況和高考常見語(yǔ)境,我們不難發(fā)現(xiàn)提前預(yù)測(cè)和抓住題干中的w很重要,即what, where, when, why等等。

1、外匯與外幣的關(guān)系:(1)外匯包括外幣,但外匯不等于就是外幣。外幣是指外國(guó)的貨幣,包括外國(guó)的紙幣、鑄幣;外匯通常是以外國(guó)貨幣表示的用于國(guó)際間結(jié)算的支付手段,具體包括外幣、外幣有價(jià)證券、外幣支付憑證等。(2)外幣屬于外匯的范圍,但不能把二者等同起來。通常情況下,只有可以自由兌換的外幣才是外匯,因?yàn)橥鈪R的實(shí)質(zhì)是國(guó)際支付手段,如果某種貨幣不能自由兌換,它就不能成為國(guó)際支付手段。外匯執(zhí)行的 主要是貨幣的支付手段的職能。(3)持有外匯意味著對(duì)外匯發(fā)行國(guó)擁有債權(quán)。持有外匯過多,一方面意味著國(guó)際支付能力強(qiáng)和有可能對(duì)外匯發(fā)行國(guó)施加影響;另一方面則意味著大量該由本國(guó)享受的資源,被借給外國(guó)利用,并要承擔(dān)外匯貶值的風(fēng)險(xiǎn)。2、關(guān)于幣值變化的分析:(1)對(duì)貨幣升值的具體分析:一個(gè)國(guó)家的貨幣升值(上?。┖?,同量的這種貨幣能比以前換 取更多的他國(guó)貨幣,買到更多的他國(guó)商品。
二、做理智的消費(fèi)者1、量入為出,適度消費(fèi)2、避免盲從,理性消費(fèi)3、保護(hù)環(huán)境,綠色消費(fèi)4、勤儉節(jié)約,艱苦奮斗十、教學(xué)反思本課的設(shè)計(jì)采用了課前下發(fā)預(yù)習(xí)學(xué)案,學(xué)生預(yù)習(xí)本節(jié)內(nèi)容,找出自己迷惑的地方。課堂上師生主要解決重點(diǎn)、難點(diǎn)、疑點(diǎn)、考點(diǎn)、探究點(diǎn)以及學(xué)生學(xué)習(xí)過程中易忘、易混點(diǎn)等,最后進(jìn)行當(dāng)堂檢測(cè),課后進(jìn)行延伸拓展,以達(dá)到提高課堂效率的目的。這節(jié)課我們主要學(xué)習(xí)了影響人們消費(fèi)的幾種消費(fèi)心理和幾種科學(xué)的消費(fèi)觀。本節(jié)課與學(xué)生生活十分貼近所以這節(jié)課充分的調(diào)動(dòng)了學(xué)生學(xué)習(xí)的興趣和積極性,并且讓學(xué)生針對(duì)案例進(jìn)行充分的分組討論分析,通過學(xué)生的展示分析和補(bǔ)充可以知道學(xué)生們不但深層次分析了教學(xué)原理也透徹理解了教學(xué)重難點(diǎn)大大提高了課堂效率.。通過案例的分析進(jìn)一步領(lǐng)會(huì)了教材原理突破了本節(jié)課的難點(diǎn)——樹立正確的消費(fèi)觀。整堂課學(xué)生求知旺盛,復(fù)雜的知識(shí)變得簡(jiǎn)單化,從閱讀教材到獨(dú)立思考分析再到合作討論最后的展示質(zhì)疑答疑,加深了印象,提高了能力。
七、教學(xué)反思這堂課有眼下看得見的效果和暫時(shí)看不見的長(zhǎng)遠(yuǎn)的效果,學(xué)生收益明顯:1.學(xué)生學(xué)到的不只是成語(yǔ)本身。學(xué)生從網(wǎng)絡(luò)上搜集材料,分析整理,不只是學(xué)成語(yǔ),探究能力也得到提高。對(duì)成語(yǔ)的梳理探究,是讓學(xué)生做一件很具體的事——梳理、分析、歸類。重在過程,重在課外、課前學(xué)生的工作。這樣的教學(xué)設(shè)計(jì)很有價(jià)值,讓學(xué)生在活動(dòng)中得到提高。2.開拓了學(xué)生的眼界。學(xué)生放眼各種報(bào)刊,從報(bào)刊中發(fā)現(xiàn)問題——大家都可能出錯(cuò)。這樣一來學(xué)生的眼界變寬了,自信心增強(qiáng)了。3.對(duì)成語(yǔ)的理解、運(yùn)用比過去深刻。讓學(xué)生從對(duì)一個(gè)個(gè)具體成語(yǔ)的理解入手,進(jìn)而認(rèn)識(shí)到以后用成語(yǔ)不能犯“望文生義”等錯(cuò)誤,從個(gè)例上升到一般。4.讓學(xué)生知道以后自己運(yùn)用成語(yǔ)應(yīng)抱什么態(tài)度,用什么方法。別人錯(cuò)用成語(yǔ),是前車之鑒。
