Help students sort out the main meaning of each paragraph and understand the narrative characteristics of "timeline” in illustrative style.3. Lead students to understand the changes that have been caused by the Internet.
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. Let's enjoy the fun of music!Thanks again for your attention!
知識和技能 ⑴從圖片和簡易圖中,了解氣團(冷氣團、暖氣團)的概念;鋒的概念與分類;低壓(氣旋)、高壓(反氣旋)、高壓脊、低壓槽的概念。⑵從氣溫、氣壓、濕度、降水、風(fēng)等幾方面分析各種天氣系統(tǒng)的形成及其氣流特點,并綜合出各種天氣系統(tǒng)控制下的天氣狀況過程與方法 ⑴讓學(xué)生能閱讀和簡單分析天氣圖,解釋天氣變化現(xiàn)象;⑵用案例說明氣象災(zāi)害發(fā)生的原因和危害;⑶結(jié)合我國常見的天氣系統(tǒng)說明其對人們生產(chǎn)和生活的影響情感、態(tài)度與價值觀激發(fā)學(xué)生探究天氣的形成和變化的興趣和動機,培養(yǎng)學(xué)生求真、求實的科學(xué)態(tài)度,提高地理審美情趣教學(xué)重點1.鋒面系統(tǒng)。(鋒面系統(tǒng):一是要區(qū)別冷暖鋒的成因,二是要掌握鋒面兩側(cè)的氣壓、溫度、濕度、風(fēng)和天氣差異)2.低壓、高壓系統(tǒng)。(要掌握其成因、氣壓特征、氣流特征及其天氣特點四個方面。)
科學(xué)家預(yù)測,就地區(qū)而言,位于低緯度的大部分國家,農(nóng)作物的產(chǎn)量將減少;而位于高緯度的國家,農(nóng)作物產(chǎn)量有可能增加。由于不少發(fā)展中國家位于低緯度地區(qū),因此,氣候變化的這種區(qū)域差異性,可能會使發(fā)展中國家所面臨的問題更為嚴(yán)峻。板書:3全球變暖將加劇水資源的不穩(wěn)定性與供需矛盾。介紹:全球變暖會影響整個水循環(huán)過程,可能使蒸發(fā)加大,改變區(qū)域降水量和降水分布格局,增加降水極端異常事件的發(fā)生,導(dǎo)致洪澇、干旱災(zāi)害的頻次和強度增加,以及地表徑流發(fā)生變化。隨著徑流減少,蒸發(fā)增強,全球變暖將加劇水資源的不穩(wěn)定性與供需矛盾。轉(zhuǎn)折:既然全球變暖會引起很多不利影響,那么作為人類應(yīng)如何面對這一挑戰(zhàn)呢?這就是我們要討論的第三個問題。板書:三、氣候變化的適應(yīng)對策討論:請大家閱讀結(jié)合教材P53氣候變化的適應(yīng)對策部分討論人類應(yīng)如何面對全球變暖這一問題 呢?
1.改善城市環(huán)境:治理河流、控制大氣污染物、大力加強綠化建設(shè)為改善城市環(huán)境,上海市全面展開對大氣、河流、噪聲等多方面的治理工作。如蘇州河的治理、降低城市污染物濃度、加強綠化建設(shè),截止1990年,市區(qū)綠化覆蓋率達到20.3%。2.改善城市交通、改善居住條件擴寬主干道,修建環(huán)城公路,修筑了南浦大橋和揚浦大橋,新修城市高架公路和地鐵,改造住宅。3.控制城市規(guī)模建立衛(wèi)星城,開發(fā)新區(qū),有效地控制城市中心區(qū)的規(guī)模。思考:什么時候許多國家采取措施保護和改善城市環(huán)境?你認為可以采取哪些措施來保護和改善城市環(huán)境?上海市保護和改善城市環(huán)境的措施:上海的衛(wèi)星城有哪些?上海新建了哪個新區(qū)?目前浦東新區(qū)在上海的地位如何?建立衛(wèi)星城和開發(fā)新區(qū)可以起到什么作用?上海市為改善交通條件,做了哪些工作?
一般情況下,凡是支持物對物體的支持力,都是支持物因發(fā)生形變而對物體產(chǎn)生彈力。所以支持力的方向總是垂直于支持面而指向被支持的物體。例1:放在水平桌面上的書書由于重力的作用而壓迫桌面,使書和桌面同時發(fā)生微小形變,要恢復(fù)原狀,對桌面產(chǎn)生垂直于桌面向下的彈力f1,這就是書對桌面的壓力;桌面由于發(fā)生微小的形變,對書產(chǎn)生垂直于書面向上的彈力f2,這就是桌面對書的支持力。學(xué)生分析:靜止地放在傾斜木板上的書,書對木板的壓力和木板對書的支持力。并畫出力的示意圖。結(jié)論:壓力、支持力都是彈力。壓力的方向總是垂直于支持面而指向被壓的物體,支持力的方向總是垂直于支持面而指向被支持的物體。引導(dǎo)學(xué)生分析靜止時,懸繩對重物的拉力及方向。引導(dǎo)得出:懸掛物由于重力的作用而拉緊懸繩,使重物、懸繩同時發(fā)生微小的形變。重物由于發(fā)生微小的形變,對懸繩產(chǎn)生豎直向下的彈力f1,這是物對繩的拉力;懸繩由于發(fā)生微小形變,對物產(chǎn)生豎直向上的彈力f2,這就是繩對物體的拉力。
l.知識與技能:(1)知道摩擦力產(chǎn)生的條件。(2)能在簡單問題中,根據(jù)物體的運動狀態(tài),判斷靜摩擦力的有無、大小和方向;知道存在著最大靜摩擦力。(3)掌握動磨擦因數(shù),會在具體問題中計算滑動磨擦力,掌握判定摩擦力方向的方法。(4)知道影響到摩擦因數(shù)的因素。2.過程與方法:通過觀察演示實驗,概括出摩擦力產(chǎn)生的條件及摩擦力的特點,培養(yǎng)學(xué)生的觀察、概括能力。通過靜摩擦力與滑動摩擦力的區(qū)別對比,培養(yǎng)學(xué)生分析綜合能力。3.情感態(tài)度價值觀:在分析物體所受摩擦力時,突出主要矛盾,忽略次要因素及無關(guān)因素,總結(jié)出摩擦力產(chǎn)生的條件和規(guī)律。二、重點、難點分析1.本節(jié)課的內(nèi)容分滑動摩擦力和靜摩擦力兩部分。重點是摩擦力產(chǎn)生的條件、特性和規(guī)律,通過演示實驗得出關(guān)系f=μN。2.難點是學(xué)生有初中的知識,往往誤認為壓力N的大小總是跟滑動物體所受的重力相等,因此必須指出只有當(dāng)兩物體的接觸面垂直,物體在水平拉力作用下,沿水平面滑動時,壓力N的大小才跟物體所受的重力相等。
1.用CAI課件模擬汽車的啟動過程。師生共同討論:①如果作用在物體上的力為恒力,且物體以勻速運動,則力對物體做功的功率保持不變。此情況下,任意一段時間內(nèi)的平均功率與任一瞬時的瞬時功率都是相同的。②很多動力機器通常有一個額定功率,且通常使其在額定功率狀態(tài)工作(如汽車),根據(jù)P=FV可知:當(dāng)路面阻力較小時,牽引力也小,速度大,即汽車可以跑得快些;當(dāng)路面阻力較大,或爬坡時,需要比較大的牽引力,速度必須小。這就是爬坡時汽車換低速擋的道理。③如果動力機器在實際功率小于額定功率的條件下工作,例如汽車剛剛起動后的一段時間內(nèi),速度逐漸增大過程中,牽引力仍可增大,即F和v可以同時增大,但是這一情況應(yīng)以二者乘積等于額定功率為限度,即當(dāng)實際功率大于額定功率以后,這種情況不可能實現(xiàn)。
(五)平拋運動規(guī)律的應(yīng)用例1:一架老式飛機在高出海面45m的高處,以80m/s的速度水平飛行,為了使飛機上投下的炸彈落在停在海面上的敵船,應(yīng)該在與轟炸目標(biāo)的水平距離為多遠的地方投彈?不計空氣阻力。分析:對于這道題我們可以從以下幾個方面來考慮:(1)從水平飛行的飛機上投下的炸彈,做什么運動?為什么?(2)炸彈的這種運動可分解為哪兩個什么樣的分運動?3)要想使炸彈投到指定的目標(biāo)處,你認為炸彈落地前在水平方向通過的距離與投彈時飛機離目標(biāo)的水平距離之間有什么關(guān)系?拓展:1、式飛機在高出海面45m的高處,以80m/s的速度水平飛行,尾追一艘以15m/s逃逸的敵船,為了使飛機上投下的炸彈正好擊中敵船,應(yīng)該在與轟炸目標(biāo)的水平距離為多遠的地方投彈?不計空氣阻力。2、在一次摩托車跨越壕溝的表演中,摩托車從壕溝的一側(cè)以速度v=40m/s沿水平方向向另一側(cè),壕溝兩側(cè)的高度及寬度如圖所示,摩托車可看做質(zhì)點,不計空氣阻力。(1)判斷摩托車能否跨越壕溝?請計算說明(2)若能跨過,求落地速度?
3.進一步體會力是產(chǎn)生加速度的原因,并通過牛頓第二定律來理解勻速圓周運動、變速圓周運動及一般曲線運動的各自特點。(三)、情感、態(tài)度與價值觀1.在實驗中,培養(yǎng)學(xué)生動手、探究的習(xí)慣。2.體會實驗的意義,感受成功的快樂,激發(fā)學(xué)生探究問題的熱情、樂于學(xué)習(xí)的品質(zhì)。教學(xué)重點1.體會牛頓第二定律在向心力上的應(yīng)用。2.明確向心力的意義、作用、公式及其變形,并經(jīng)行計算。教學(xué)難點1.對向心力的理解及來源的尋找。2.運用向心力、向心加速度的知識解決圓周運動問題。教學(xué)過程(一)、 引入新課:復(fù)習(xí)提問:勻速圓周運動的物體的加速度——向心加速度,它的方向和大小有何特點呢?學(xué)生回答后進一步引導(dǎo):那做勻速圓周運動物體的受力有什么特點呢?是什么力使物體做圓周運動而不沿直線飛出?請同學(xué)們先閱讀教材
①標(biāo)題——標(biāo)題應(yīng)當(dāng)簡潔明了。②導(dǎo)語——導(dǎo)語是消息開頭的第一段或第一句話,簡明扼要地揭示出消息的核心內(nèi)容。③主體——主體是消息的主要部分,要用充足的事實表現(xiàn)主題,對導(dǎo)語的內(nèi)容作進一步的展開和闡述。④結(jié)束語——通常是對全文內(nèi)容進行概括性的總結(jié)。3. 新聞報道增分句子(1)陳述事實常用的句型:①A terrible storm hit/struck ... , killing ..②It was a cool autumn night when the earthquake happened. A large number of buildings fell down and roads were destroyed, leaving a great many people homeless.地震發(fā)生在一個涼爽的秋夜。大量的建筑物倒塌,道路被毀,許多人無家可歸。③With the help of the rescue team, people who were the trapped in the flood were saved.在救援隊的幫助下,困在洪水中的人們得救了。(2)陳述觀點常用的句型:①Clearly/Obviously/In my opinion/It seemed that people were shocked.顯然/在我看來/似乎人們震驚了。②The whole city was in ruins after the earthquake.地震后整個城市成了一片廢墟。(3)揭示原因常用的句型:Because of/As a result of/Thanks to the help of the army, people who got injured were sent to the hospital immediately.
【教材分析】本節(jié)課是高中英語第一冊的最后一個單元的閱讀和思考部分,文章難度明顯增加,體現(xiàn)在以下幾個方面:文章題材是說明文,比較難理解;話題生疏,涉及到歷史等知識;生詞量增大,而且在語境中理解詞匯的要求提高。面對這些,教師的難度和高度也要有所提升,通過探討說明順序,了解背景知識等幫助他們找到說明文閱讀的方法?!窘虒W(xué)目標(biāo)與核心素養(yǎng)】1. 文化意識目標(biāo)新課程中指出,文化意識是對中外文化的理解和對優(yōu)秀文化的認同。文化意識的的培養(yǎng)有助于學(xué)生增加國家認同和家國情懷,成為有文明素養(yǎng)和社會責(zé)任感的人。我們這個單元很好體現(xiàn)了這一點,通過了解漢字書寫的體系和發(fā)展,學(xué)生可以有一種文化自豪感,同時也能夠幫助學(xué)生深入挖掘這篇文章,從而想到更多和中國文化相關(guān)的方面。2. 學(xué)習(xí)能力目標(biāo)
Listening and Speaking introduces the topic of “Take part in a youth project”. The listening text is an interview about an international youth cultural heritage protection project. More than 20 high school students from seven countries participated in the project. The reporter interviewed two participants Stephanie and Liu Bin. By listening to the text, students can understand the significance of cultural heritage protection, and teenagers can use their knowledge, combine their own interests and advantages, etc. to participate in the action of cultural heritage protection. Listening and Talking introduces the theme of "Talk about history and culture". The listening text is a dialogue between two tourists and tour guides when they visit the Kremlin, red square and surrounding buildings. The dialogue focuses on the functional items of "starting a conversation", which is used to politely and appropriately attract the attention of the others, so as to smoothly start a conversation or start a new topic. The purpose of this section is to guide students to understand the history and current situation of Chinese and foreign cultural heritage in their own tourism experiences or from other people's tourism experiences, explore the historical and cultural values, and be able to express accurately and appropriately in oral communication.1. Guide students to understand the content of listening texts in terms of the whole and key details; 2. Cultivate students' ability to guess the meaning of words in listening; discuss with their peers how to participate in cultural heritage protection activities.3. Instruct students to use functional sentences of the dialogue such as “I beg your pardon, but…” “Forgive me for asking, but…" and so on to start the conversation more politely and appropriately.
The activity topic of this section is "report an ongoing event", and the structure is the passive voice of present continuous tense. Rare wild animals are suffering from large-scale poaching, and species are on the brink of danger. Rescue operations are underway. "Being" and "suffering" are the meanings of the present progressive passive voice.The usage of present progressive passive voice is of great importance in writing a good discourse and appreciating some difficult language items, so it is vital to master it and use it flexibly in a context.1. Motivate Ss to deepen the understanding of the usage of present progressive passive voice in a fixed context.2. Enable Ss to master the usage of present progressive passive voice and use it flexibly in a context.3. Lead Ss to construct sentences or appreciate sentences used master it and use it flexibly in a context.1. Help students to appreciate the function of the usage of present progressive passive voice in a sentence2. Instruct students to write essays using the proper usage of present progressive passive voice.Look at the picture and tell me what are workers doing? What is the house being done?
