Instead, they use the new technology to model the various parts and wonderful virtual harmony group of music in the family. Students need to understand the main meaning of each paragraph. Finding topic sentences is an important way to understand the general idea of a paragraph. After the topic sentence, it is usually the detail sentence that supports and explains the topic sentence. Some paragraphs have obvious subject sentences, for example, the first sentence of the second paragraph is the subject sentence of the paragraph, and the following sentenceStudents need to pay attention to the topic sentences and key sentences, and then pay attention to how the sentences after the meaning explain, explain and support the topic sentences or key sentences before.1.Guide students to learn about experiencing music online2.Guide students to scan and circle the information in the text.3.Guide students to find the numbers and dates to fill in the timeline.4.Guide students to learn more about music by completing the sentences with the correct forms of the words and phrases. And then make a mind map about the outline of the passage.1. Guide students to pay attention to reading strategies, such as prediction, self-questioning and scanning.2.

The Internet celebrity Gao Yifeng. Years ago, he owned 5 companies and the staffs over 1,000, but during the economy crisis, he became nothing but debt. He was so worried that his hair became white overnight. There was a time when he wanted to killed himself. But after listening to the song Start Over by Liu Huan, he decided to cheer himself up. He started a steamed bun shop and gradually became a national chain shops. Now he became successful again.Walter Haddon said, “Music is the medicine of a troubled mind.” Music contains such a pleasant and inspiring force. Music gave him courage and bravery. When he listened to the song, it made his spirit fly like a kite in the wind. Music gave him strength and brought him relief. It was the rock I leant on to become strong and to get through those hard times. I hope none of us have to go through the same kind of suffering that he did. At the same time, we all go through various periods when we feel sad or alone. During those times, music can help us in the same way that it helped him. I hope we all will somehow begin to treasure music and make it a part of our life. Thank you for your listening !5.Revise your writing each other.Does he/she explain how music has changed his/her/someone else’s life?Are some of the rhetorical devices included and used properly ?Does he/she talk about how music makes him/her/someone feel?Is the first word in each sentences capitalised?Does he/she use correct punctuation ?

My topic is: love music like love yourself.Music is like the air we need to maintain our normal lives around us. You can't imagine how terrible a world without music would be. Movies and TV shows have no music, only dry conversations and scenes; mobile phones only vibrations; streets only noisy crowds; cafes, western restaurants only depressed meals. What a terrible world it is!As a student, I hope we all can enjoy the fun brought by music in our spare time. Instead of just listening to music, we can even make our own music.

1.生產(chǎn)上的聯(lián)系:有投入——產(chǎn)出的關(guān)系工業(yè)生產(chǎn)的過程復(fù)雜,工序繁多,往往需要經(jīng)過多家工廠的加工才能完成一種產(chǎn)品的生產(chǎn)過程。因此,在這些工廠之間就存在著產(chǎn)品與原料的聯(lián)系。一家工廠生產(chǎn)的產(chǎn)品是另一家工廠的原料,這兩家工廠之間就形成了工序上的工業(yè)聯(lián)系。2.非生產(chǎn)上的聯(lián)系:如地理空間上的聯(lián)系布局在同一個(gè)工業(yè)區(qū)內(nèi),共同利用工業(yè)區(qū)的道路、供水、供電、通信等基礎(chǔ)設(shè)施以及其他生產(chǎn)、生活服務(wù)設(shè)施,或者共同利用當(dāng)?shù)亓畠r(jià)的勞動力,形成了空間利用上的工業(yè)聯(lián)系。我國許多地方的經(jīng)濟(jì)技術(shù)開發(fā)區(qū)就是建立在這種工業(yè)聯(lián)系基礎(chǔ)上的。(二)工業(yè)集聚1.形成具有工業(yè)聯(lián)系的一些工廠往往近距離地聚集起來,形成工業(yè)集聚現(xiàn)象。2.工業(yè)集聚可獲得效應(yīng)(1)工業(yè)集聚可以加強(qiáng)企業(yè)間的信息交流和技術(shù)協(xié)作,降低中間產(chǎn)品的運(yùn)輸費(fèi)用和能源消耗,進(jìn)而降低生產(chǎn)成本,提高生產(chǎn)效率和利潤,取得規(guī)模效益。

(四)反思總結(jié),當(dāng)堂檢測。本節(jié)內(nèi)容講述了價(jià)格變動對人們生活、生產(chǎn)的影響作用,主要知識框架如下:(1)、價(jià)格變動會影響人們的消費(fèi)需求,商品價(jià)格上漲,人需求就減少,反之,則增大。價(jià)格變動對不同商品需求影響程度是不一樣的,對生活必需品的需求量影響較小,對高檔耐用品的需求量影響較大。相關(guān)商品價(jià)格變動對消費(fèi)需求的影響不同,某種商品價(jià)格上漲,就會減少需求量,其替代品需求量增加,其互補(bǔ)品需求量則減少。(2)、價(jià)格變化也會影響生產(chǎn)經(jīng)營,價(jià)格變動會調(diào)節(jié)生產(chǎn),刺激生產(chǎn)者改進(jìn)技術(shù),提高勞動生產(chǎn)率,促使生產(chǎn)者生產(chǎn)適銷對路的高 質(zhì)量產(chǎn)品。(五)發(fā)導(dǎo)學(xué)案、布置預(yù)習(xí)。預(yù)習(xí)第三課第一框《消費(fèi)及其類型》,完成預(yù)習(xí)導(dǎo)學(xué)案練習(xí)題九、板書設(shè)計(jì)《價(jià)格變動的影響》1、對人們生活的影響(1)商品價(jià)格變動與消費(fèi)需求量之間的關(guān)系(2)不同商品的需求量對價(jià)格變動的反應(yīng)程度不同
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,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)動了學(xué)生學(xué)習(xí)的興趣和積極性,并且讓學(xué)生針對案例進(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)雜的知識變得簡單化,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。
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。外幣是指外國的貨幣,包括外國的紙幣、鑄幣;外匯通常是以外國貨幣表示的用于國際間結(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)是國際支付手段,如果某種貨幣不能自由兌換,它就不能成為國際支付手段。外匯執(zhí)行的 主要是貨幣的支付手段的職能。(3)持有外匯意味著對外匯發(fā)行國擁有債權(quán)。持有外匯過多,一方面意味著國際支付能力強(qiáng)和有可能對外匯發(fā)行國施加影響;另一方面則意味著大量該由本國享受的資源,被借給外國利用,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)對貨幣升值的具體分析:一個(gè)國家的貨幣升值(上?。┖螅康倪@種貨幣能比以前換 取更多的他國貨幣,買到更多的他國商品。
本來比較速度變化的快慢也有兩種方法:一種是比較相同時(shí)間內(nèi)速度變化量的大??;另一種是比較發(fā)生相同的速度變化所需要的時(shí)間長短。但教材是將比較質(zhì)點(diǎn)位置移動快慢的思想直接遷移過來,通過實(shí)例分析,使學(xué)生明白不同運(yùn)動物體的速度變化快慢不同,表現(xiàn)在速度的變化與發(fā)生這個(gè)變化所用時(shí)間的比值不同,從而引入加速度的定義方法a=△v/△t。加速度表示速度的變化快慢,包括速度增加的快慢和減小的快慢,不能誤認(rèn)為只要有加速度的運(yùn)動速度就一定是增加的。廣義地講,加速度不僅可以描述速度大小的變化快慢,而且也可以描述速度方向變化的快慢,本節(jié)教材只限定在直線運(yùn)動的情景中討論。加速度的矢量性是一個(gè)難點(diǎn),教材是以與速度方向相同或是相反來表述加速度的矢量性的。如果以初速度方向?yàn)檎较颍敲醇铀俣染陀姓?fù)之分,加速度的正負(fù)表示加速度的方向,不表示加速度的大小。
(三)合作交流能力提升教師:剛才我們通過實(shí)驗(yàn)了解了小車的速度是怎樣隨時(shí)間變化的,但實(shí)驗(yàn)中有一定的誤差,請同學(xué)們討論并說出可能存在哪些誤差,造成誤差的原因是什么?(每個(gè)實(shí)驗(yàn)小組的同學(xué)之間進(jìn)行熱烈的討論)學(xué)生:測量出現(xiàn)誤差。因?yàn)辄c(diǎn)間距離太小,測量長度時(shí)容易產(chǎn)生誤差。教師:如何減小這個(gè)誤差呢?學(xué)生:如果測量較長的距離,誤差應(yīng)該小一些。教師:應(yīng)該采取什么辦法?學(xué)生:應(yīng)該取幾個(gè)點(diǎn)之間的距離作為一個(gè)測量長度。教師:好,這就是常用的取“計(jì)數(shù)點(diǎn)”的方法。我們應(yīng)該在紙帶上每隔幾個(gè)計(jì)時(shí)點(diǎn)取作一個(gè)計(jì)數(shù)點(diǎn),進(jìn)行編號。分別標(biāo)為:0、1、2、3……,測各計(jì)數(shù)點(diǎn)到“0”的距離。以減小測量誤差。教師:還有補(bǔ)充嗎?學(xué)生1:我在坐標(biāo)系中描點(diǎn)畫的圖象只集中在坐標(biāo)原定附近,兩條圖象沒有明顯的分開。學(xué)生2:描出的幾個(gè)點(diǎn)不嚴(yán)格的分布在一條直線上,還能畫直線嗎?
教師活動:(1)組織學(xué)生回答相關(guān)結(jié)論,小組之間互相補(bǔ)充評價(jià)完善。教師進(jìn)一步概括總結(jié)。(2)對學(xué)生的結(jié)論予以肯定并表揚(yáng)優(yōu)秀的小組,對不理想的小組予以鼓勵(lì)。(3)多媒體投放板書二:超重現(xiàn)象:物體對支持物的壓力(或?qū)覓煳锏睦?大于物體所受到的重力的情況稱為超重現(xiàn)象。實(shí)質(zhì):加速度方向向上。失重現(xiàn)象:物體對支持物的壓力(或?qū)覓煳锏睦?小于物體所受到的重力的情況稱為失重現(xiàn)象。實(shí)質(zhì):加速度方向向下。(4)運(yùn)用多媒體展示電梯中的現(xiàn)象,引導(dǎo)學(xué)生在感性認(rèn)識的基礎(chǔ)上進(jìn)一步領(lǐng)會基本概念。4.實(shí)例應(yīng)用,結(jié)論拓展:教師活動:展示太空艙中宇航員的真實(shí)生活,引導(dǎo)學(xué)生應(yīng)用本節(jié)所學(xué)知識予以解答。學(xué)生活動:小組討論后形成共識。教師活動:(1)引導(dǎo)學(xué)生分小組回答相關(guān)問題,小組間互相完善補(bǔ)充,教師加以規(guī)范。(2)指定學(xué)生完成導(dǎo)學(xué)案中“思考與討論二”的兩個(gè)問題。
培養(yǎng)學(xué)生合作交流意識和探究問題的能力,這一部分知識層層遞進(jìn),符合學(xué)生由特殊到一般、由簡單到復(fù)雜的認(rèn)知規(guī)律。4、互動探究(1)極限思想的滲透讓學(xué)生閱讀“思考與討論”小版塊.培養(yǎng)學(xué)生的自學(xué)和閱讀能力提出下列問題,進(jìn)行分組討論:a、用課本上的方法估算位移,其結(jié)果比實(shí)際位移大還是小?為什么?b、為了提高估算的精確度,時(shí)間間隔小些好還是大些好?為什么?針對學(xué)生回答的多種可能性加以評價(jià)和進(jìn)一步指導(dǎo)。讓學(xué)生從討論的結(jié)果中歸納得出:△t越小,對位移的估算就越精確。滲透極限的思想。通過小組內(nèi)分工合作,討論交流,培養(yǎng)學(xué)生交流合作的精神,以及搜集信息、處理信息的能力;通過小組間對比總結(jié),使學(xué)生學(xué)會在對比中發(fā)現(xiàn)問題,在解決問題過程中提高個(gè)人能力;
設(shè)計(jì)意圖:幾道例題及練習(xí)題,其中例1小車由靜止啟動開始行駛,以加速度 做勻加速運(yùn)動,求2s后的速度大小?進(jìn)而變式到:小車遇到紅燈剎車……,充分體現(xiàn)了“從生活到物理,從物理到社會”的物理教學(xué)理念;例題及練習(xí)題由淺入深、由易到難、各有側(cè)重,體現(xiàn)新課標(biāo)提出的讓不同的學(xué)生在物理上得到不同發(fā)展的教學(xué)理念。這一環(huán)節(jié)總的設(shè)計(jì)意圖是反饋教學(xué),內(nèi)化知識。(6) 小結(jié)歸納,拓展深化我的理解是,小結(jié)歸納不應(yīng)該僅僅是知識的簡單羅列,而應(yīng)該是優(yōu)化認(rèn)知結(jié)構(gòu),完善知識體系的一種有效手段,為充分發(fā)揮學(xué)生的主題作用,從學(xué)習(xí)的知識、方法、體驗(yàn)是那個(gè)方面進(jìn)行歸納,我設(shè)計(jì)了這么三個(gè)問題:① 通過本節(jié)課的學(xué)習(xí),你學(xué)會了哪些知識;② 通過本節(jié)課的學(xué)習(xí),你最大的體驗(yàn)是什么;③ 通過本節(jié)課的學(xué)習(xí),你掌握了哪些學(xué)習(xí)物理的方法?
