1:Teenagers should be allowed to choose their own clothes.(1)should be allowed 為含有情態(tài)動詞的被動語態(tài),英語動詞有兩種語態(tài),既主動語態(tài)和被動語態(tài),主動語態(tài)表示主語是動作的執(zhí)行者,被動語態(tài)表示主語是動作的承受者.被動語態(tài)的構(gòu)成:主語+be+及物動詞的過去分詞 be有人稱和時態(tài)的變化.Eg: 我們學(xué)校每年都栽樹.Trees in our school every year..被動語態(tài)的用法:(1)不知道動作的執(zhí)行者是誰。這棟樓是5年前建的。The building was built 5 years ago.(2)沒有必要指出誰是動作的執(zhí)行者。校園天天都被打掃。
The school yard every day.(3)需要強(qiáng)調(diào)動作的承受者。

pets
Reading Objectives To learn about rhyme schemes, stress and intonation of poetry To learn new vocabulary to talk about pets To read about animal behaviors Background information This section introduces students to poetry.The three short poems are different not only in the choice of pets, but also in the way they focus on different aspects of animals.The style of each poem is different.‘My Dog’ focuses on behaviors adjectives.‘My Goldfish’ expresses the poet’s feelings about the goldfish’s lifestyle.‘Cats’ describes the different places where cats sleep.Part A Teaching procedures Ask students to study the poems and pictures on page 90.Write the title ‘My Dog’ on the board and also the verb that are used in the poem: ‘chase’, ’catch’, ’hunts’, ’hide’, ’builds’, ‘bark’, ‘bite’, ‘fight’ and ‘look after’.Talk about their meanings.For weaker classes, read ‘My Dog’ one like at a time and have students repeat after you.For stronger classes, choose five students to read two lines each.Ask students to find the adjectives in the poem which tell us about its characteristics, e.g., ‘cleverest’.Work through the meaning of ‘wonderful tricks’.Then ask them to identify the verbs which describe the dog’s actions(‘chase’, ‘catch’, ‘hunts’, ‘builds’, ‘bark’, ‘bite’ and ‘fight’).Ask students some general questions to elicit details about the dog’s actions to generate some of the key verbs, e.g., what does the dog do? For weaker classes, read the poem ‘My Goldfish’ and ask students to follow in their books.Explain the meaning of ‘miaow’ and ‘bubbles’.For stronger classes, ask two students to each read a stanza.Read the poem ‘Cats’.As you read the poem, try to use gestures and mines to illustrate the different impressions presented in the poem.Learn about the words ‘window-ledge’, ‘edge’, ‘drawer’, ‘lap’, ‘cardboard box’ and ‘frocks’.Ask more able students to read the ‘Cats’ poem, first on their own and then with a partner.S1 reads lines 26-35 and S2 reads lines 36-46.Ask if any students have cats that like to sleep in unusual places.Have the class prepare this poem for choral reciting.Allocate different lines to individual students or pairs to create a dramatic impression.Ask one or two students to read one line only, e.g., S1: Cats All: Cats sleep anywhere, S2: Any table, S3: Any chair, S4: Top of piano, This activity helps students to work as a team as they have to listen to their cues, which encourages them to work collaboratively.Ask students which poem they like best.Encourage more able students to say why they like it, e.g., I like the poem about cats because they are my favorite animals.Extension activity For stronger classes, ask students to copy the poem ‘Cats’ into their books, leaving enough space to draw the different objects to illustrate where cats live and sleep.Encourage students to interpret the use of prepositions to prepare a correct visual presentation of the poem.Part B Teaching procedures 1 Read the words listed in the box in part B1 to the class.Ask students to repeat each one and to pay particular attention to the sounds of the final syllables.Ask students to complete the sentences with the correct words.Encourage them to read the sentences out loud so that they can hear the sounds of the words.For weaker classes, you may need to read out the first word of each sentence slowly and ask students to repeat them before they start completing the sentences.Ask less able students to work with a partner and take turns saying the rhyming pairs aloud.Ask less able students to do the extra questions on page 91.For more able students, do not provide them with the extra gapped sentences and words.Ask them to look for other rhyming pairs in the poems themselves.Ask students whether they think the rhyming words make the poems more pleasant to listen to.Accept all opinions.Then ask individual students what are the other roles of the rhyme in poetry.Elicit as many opinions as possible, e.g., makes poetry easier to remember, creates a beat at the end of each line, helps create a pattern of sounds and a sound rhythm, creates a tune, helps create the images, etc.Explain the context and the instructions to part B2.Review the words in the box.Then ask students to complete the sentences with the correct words.Ask two volunteers to read out the completed articles.Extension activity Ask more able students to find any other rhyming pairs from the words learned in other units.Give them a reward for finding one, two or more.This is a very useful pronunciation exercise as well as an activity which prepares students to use language creatively on their own.Part C Teaching procedures Ask students to do Part C1 in pairs.Encourage them to use a dictionary if necessary.Review the answer and clarify any areas of uncertainty.Ask students to do Part C2 on their own.Remind them that all the words can be found in the poem ‘My Goldfish’ on page 90.Ask more able students to do the task without referring the poem.Tell less able students to find the words in the poem to complete what Peter says.Read out the first line.Then ask four students to read out one line each.To do part C3, students will have to refer to the poem ‘Cats’ on page 90.Ask more able students to do the task on their own.Less able students may need help.Provide them with the names of places, and perhaps how many times each preposition is used.Ask more able students where cats sleep based on the poem ‘Cats’ on page 90.Tell them that they can use any other words apart from ‘in’, ’on’ and ‘on top of’.

第十六章第五節(jié)
機(jī)械能及其轉(zhuǎn)化
一.教學(xué)目標(biāo)
1.知識與技能
(1)知道機(jī)械能包括動能和勢能。
(2)能正確理解有關(guān)動能和勢能之間相互轉(zhuǎn)化的簡單現(xiàn)象。
(3)初步了解機(jī)械能守恒的含義。
2.過程與方法
通過觀察和實(shí)驗(yàn),培養(yǎng)學(xué)生觀察能力和分析歸納能力。
3.情感態(tài)度和價(jià)值觀
(1)關(guān)心機(jī)械能與人們生活的聯(lián)系,有將機(jī)械能應(yīng)用于生活的意識。
(2)培養(yǎng)學(xué)生具有愛國意識。
二、學(xué)習(xí)者的分析
學(xué)生來自于城鎮(zhèn),有豐富的知識背景,接觸許多包含著豐富物理知識的簡單或復(fù)雜的事物,為這節(jié)特殊的教學(xué)過程奠定基礎(chǔ)。
三、教具與學(xué)具
學(xué)生用實(shí)驗(yàn)器材:學(xué)生4人一組、滾擺、鐵鎖、細(xì)繩.鐵架臺
老師演示用實(shí)驗(yàn)器材:溜溜球.鐵架臺.鋼球.細(xì)線.帶彈簧的斜面
四.教學(xué)課時:1時
五.教學(xué)過程:
引入新課:
一.我們在初二的時候就已經(jīng)學(xué)習(xí)過關(guān)于能量的轉(zhuǎn)化,請回答,電燈工作的時候,能量是怎么轉(zhuǎn)化的?風(fēng)力發(fā)電機(jī)工作的時候,能量是怎么轉(zhuǎn)化的?水利發(fā)動機(jī)工作的時候,能量是怎么轉(zhuǎn)化的?電動機(jī)工作的時候,能量是怎么轉(zhuǎn)化的?
學(xué)生討論回答
二.情景:老師操作溜溜球,吸引學(xué)生注意力,并切入主題
(教師先通過提出一個關(guān)于能量轉(zhuǎn)化的問題,引起學(xué)生思考,并由所設(shè)計(jì)的情景,將學(xué)生引入學(xué)習(xí))
動手動腦搞探究:
一.老師提問:為什么溜溜球在松手后能夠不停的上下運(yùn)動呢?這需要學(xué)生自己探究:
實(shí)驗(yàn)1:滾擺實(shí)驗(yàn)。
出示滾擺,并簡單介紹滾擺的構(gòu)造及實(shí)驗(yàn)的做法。事先應(yīng)在擺輪的側(cè)面某處涂上鮮明的顏色標(biāo)志,告訴學(xué)生觀察顏色標(biāo)志,可以判斷擺輪轉(zhuǎn)動的快慢。
二.學(xué)生實(shí)驗(yàn)
老師展示課件引導(dǎo)學(xué)生復(fù)述并分析實(shí)驗(yàn)中觀察到的現(xiàn)象。開始釋放擺輪時,擺輪在最高點(diǎn)靜止,此時擺輪只有重力勢能,沒有動能。擺輪下降時其高度降低,重力勢能減少;擺輪旋轉(zhuǎn)著下降;而且越轉(zhuǎn)越快,其動能越來越大。擺輪到最低點(diǎn)時,轉(zhuǎn)動最快,動能最大;其高度最低,重力勢能最小。在擺輪下降的過程中,其重力勢能逐漸轉(zhuǎn)化為動能。
仿照擺輪下降過程的分析,得出擺輪上升過程中,擺輪的動能逐漸轉(zhuǎn)化為重力勢能。
加強(qiáng)鞏固
一.老師展示實(shí)驗(yàn)2:單擺實(shí)驗(yàn)。
綜述實(shí)驗(yàn)1、2,說明動能和重力勢能是可以相互轉(zhuǎn)化的。
二.老師展示實(shí)驗(yàn)3:彈性勢能和動能的相互轉(zhuǎn)化。
得出:動能和彈性勢能也是可以相互轉(zhuǎn)化的。
自然界中動能和勢能相互轉(zhuǎn)化的事例很多。首先分析課本圖15.5-2,加深學(xué)生對動能,勢能轉(zhuǎn)化的認(rèn)識,再請學(xué)生列舉生活中動,勢能轉(zhuǎn)化的實(shí)例,老師和學(xué)生共同分析.概括結(jié)論
一.學(xué)生總結(jié),老師補(bǔ)充,得出結(jié)論:
動能和勢能可以相互轉(zhuǎn)化
二.引出機(jī)械能的定義:
動能和勢能之和
拓展知識
一.學(xué)生分組做教材中的“想想做做”,請學(xué)生分析現(xiàn)象產(chǎn)生的原因,分析這其中是否有其他能量的轉(zhuǎn)化
二.假設(shè)沒有阻力,會怎么樣呢?引出機(jī)械能守恒規(guī)律
三.再次分析溜溜球在運(yùn)動過程中的機(jī)械能的變化情況

結(jié):
請同學(xué)們總結(jié)一下,本節(jié)課你學(xué)到了哪些知識,有哪些收獲?
布置作業(yè):
課本“動手動腦學(xué)在講授完這節(jié)課后,物理”1.3.4.6 教學(xué)反思:
我有了如下反思:
1、明確教學(xué)目標(biāo)。能從知識與技能、過程與方法、情感態(tài)度與價(jià)值觀三個方面來確定教學(xué)目標(biāo),符合《物理新課程標(biāo)準(zhǔn)》。教學(xué)過程設(shè)計(jì)注意緊密地圍繞著教學(xué)目標(biāo)。在教材處理和教法選擇上,注意從學(xué)生探究與交流的角度突破難點(diǎn)、突出重點(diǎn)。
2、教學(xué)思路設(shè)計(jì),符合教學(xué)內(nèi)容實(shí)際,符合學(xué)生實(shí)際,教學(xué)思路層次清晰,各個教學(xué)環(huán)節(jié)的過渡很自然、到位。在整個教學(xué)設(shè)計(jì)中,我始終發(fā)揮著課堂組織者和學(xué)習(xí)引導(dǎo)者的作用,使學(xué)生通過活動、觀察、思考、討論、歸納、交流等行為自然地掌握所學(xué)知識,這一點(diǎn)充分體現(xiàn)了“以學(xué)生的主體、以教師為主導(dǎo)”的新課程理念。
3、充分發(fā)揮現(xiàn)代教學(xué)技術(shù)的作用。這節(jié)課應(yīng)用了多媒體教學(xué),選擇了許多圖片和視頻,使許多實(shí)例直觀的呈現(xiàn)在學(xué)生眼前,比如自己拍的過山車視頻,各種機(jī)械能轉(zhuǎn)化的動畫等,這樣是學(xué)生對知識的應(yīng)用不僅僅限制的文字的理解上,而是直接將知識與實(shí)際聯(lián)系起來。同時也沒有脫離物理實(shí)驗(yàn)的作用,有效的把課件和實(shí)驗(yàn)結(jié)合在了一起。
4、注意物理與生活的緊密聯(lián)系。每個重要的知識點(diǎn)的得出都能先根據(jù)學(xué)生的一些已有經(jīng)驗(yàn)總結(jié),學(xué)完以后讓學(xué)生列舉相關(guān)的生活實(shí)例。這樣既能達(dá)到練習(xí)鞏固知識點(diǎn)的目的,同時又體現(xiàn)從生活走向物理,從物理走向社會的新課程教學(xué)理念。當(dāng)然,本課設(shè)計(jì)的不足也還是有不少的。比如:
1、學(xué)生交流討論的時間不足,沒有充分發(fā)揮學(xué)生相互的評價(jià)作用。
2、細(xì)節(jié)不夠完美。有些設(shè)計(jì)我雖然感覺很好,但學(xué)生可能是生活經(jīng)驗(yàn)不足不好理解,造成了課堂還不夠熱烈。
以上是我對這節(jié)課的反思,如有不當(dāng)之處,懇請各位領(lǐng)導(dǎo)和老師批評指正!在今后物理教學(xué)中我會不斷的反思,在反思中不斷進(jìn)步。
第五篇:九年級歷史下學(xué)期集體備課教案
九年級歷史下學(xué)期集體備課教案
第10課 歐洲聯(lián)盟
(1課時)
主講:胡永飛
成員:周紹立
吳開楊
一、教學(xué)目標(biāo): 1.知識與能力: 知道歐洲聯(lián)盟; 2.過程與方法:
知道歐洲聯(lián)盟;
3、情感態(tài)度與價(jià)值觀:
使學(xué)生能夠了解戰(zhàn)后歐洲資本主義進(jìn)一步發(fā)展的主要史實(shí)、特點(diǎn)及其原因;認(rèn)識到科學(xué)技術(shù)作為第一生產(chǎn)力所發(fā)揮的作用越來越大,在科技革命推動下,資本主義國家進(jìn)行了一系列的自我調(diào)節(jié)和改良,經(jīng)濟(jì)有了較大的新發(fā)展,但是在發(fā)展過程中矛盾重重,經(jīng)歷了曲折和波動。二.教學(xué)重點(diǎn)和難點(diǎn)
概要了解第二次世界大戰(zhàn)后歐洲資本主義世界發(fā)展變化的基本狀況。
三、學(xué)法指導(dǎo):質(zhì)疑導(dǎo)學(xué)法
四、課時安排:一課時
五、教學(xué)過程: 導(dǎo)入:
向?qū)W生展示《重建柏林》和《1950~1970年主要資本主義國家經(jīng)濟(jì)年平均增長率的比較》,讓學(xué)生從圖表中直接感覺戰(zhàn)后西歐經(jīng)濟(jì)發(fā)展的步伐,并由此引導(dǎo)學(xué)生思考:戰(zhàn)后西歐為什么能夠獲得迅速發(fā)展?也可運(yùn)用教材上有關(guān)“歐盟”的幾張圖片,引導(dǎo)學(xué)生思考:“歐盟”的前身是什么組織?這個組織是在怎樣的背景下建立的?它們的建立對世界產(chǎn)生了哪些重要影響,等等。激起學(xué)生學(xué)習(xí)的興趣后,再導(dǎo)入新課。
(一)、戰(zhàn)后初期西歐經(jīng)濟(jì)的恢復(fù)和發(fā)展
1、圖片《重建柏林》、《二戰(zhàn)后的歐洲城市》等
(戰(zhàn)爭的巨大破壞,一片廢墟,當(dāng)時人們對歐洲的重建普遍不抱任何希望,有人甚至認(rèn)為僅把柏林市的瓦礫清除干凈就需要20年的時間,要想復(fù)興簡直比登天還難。事實(shí)果真如此嗎?)
2、課堂討論:戰(zhàn)后西歐經(jīng)濟(jì)的恢復(fù)發(fā)展的主要原因有哪些?
(教師及時引導(dǎo):高素質(zhì)的勞動力是由于工業(yè)革命以及第二次工業(yè)革命使得西歐在人才、技術(shù)、管理經(jīng)驗(yàn)甚至對外經(jīng)濟(jì)聯(lián)系方面都具有很大的優(yōu)勢,為西歐經(jīng)濟(jì)恢復(fù)與發(fā)展奠定了較好基礎(chǔ)。采用最先進(jìn)的科技成果是由于伴隨著第三次科技革命的進(jìn)行,西方資本主義國家又先后投資建立了一系列新興工業(yè),如核能、計(jì)算機(jī)、激光、宇航等。同時,又對傳統(tǒng)的工業(yè)部門,如鋼鐵、汽車制造等進(jìn)行了固定資本的投資和技術(shù)改造,對農(nóng)業(yè)部門也注意提高農(nóng)業(yè)機(jī)械化的程度。現(xiàn)代科學(xué)技術(shù)轉(zhuǎn)化為生產(chǎn)技術(shù)后,極大的促進(jìn)了戰(zhàn)后西方主要資本主義國家經(jīng)濟(jì)的高速發(fā)展。其次,戰(zhàn)后美國加大對西歐的經(jīng)濟(jì)援助在客觀上為西歐國家經(jīng)濟(jì)的恢復(fù)和發(fā)展提供了必要的物質(zhì)條件。恰當(dāng)?shù)慕?jīng)濟(jì)發(fā)展政策,指的是西歐國家加強(qiáng)了對經(jīng)濟(jì)的宏觀指導(dǎo),利用國家力量推動資本主義經(jīng)濟(jì)的發(fā)展。有利于國家對經(jīng)濟(jì)生活的干預(yù)和調(diào)節(jié),促進(jìn)了對基礎(chǔ)工業(yè)和新興產(chǎn)業(yè)的投資,)
3、看圖學(xué)史:《馬歇爾計(jì)劃的受援國》
(教師啟發(fā)式提問:歐盟包括哪些國家?它的前身是個什么組織?)
(二)、歐洲共同體的形成
1、特色論壇:歐共體建立的原因是什么?
(西歐國家感到:美蘇兩國對西歐都有野心,要提高自身的安全系數(shù),提高西歐國家的國際地位,加快經(jīng)濟(jì)發(fā)展步伐,必須密切聯(lián)系加強(qiáng)合作,于是60年代建立“歐共體”。西歐國家希望通過建立一個經(jīng)濟(jì)共同體來振興經(jīng)濟(jì)并降低未來戰(zhàn)爭的可能性。)
2、思維拓展:歐洲聯(lián)盟成立后,這些國家人民的生活將會發(fā)生哪些變化?
(三)歐洲聯(lián)盟的建立
1993年,西歐國家在歐洲共同體的基礎(chǔ)上建立了歐洲聯(lián)盟,簡稱歐盟。使用統(tǒng)一貨幣——?dú)W元。歐盟成員國內(nèi)部人員、資本和貨物可自由流通,不同國家的人可以自由自在地在任何一個成員國工作、學(xué)習(xí)或居住;同時,歐盟還力求在外交和國家安全方面步調(diào)一致。歐盟成為世界上最大的經(jīng)濟(jì)體。
六、本課小結(jié)
1、促進(jìn)歐洲走向聯(lián)合的根本原因是戰(zhàn)后歐洲經(jīng)濟(jì)的迅速恢復(fù)和發(fā)展
2、歐洲走向聯(lián)合的兩個階段:歐洲共同體—→歐洲聯(lián)盟;由經(jīng)濟(jì)合作—→經(jīng)濟(jì)政治一體化
3、影響:見p56影響
七、板書設(shè)計(jì)
(一)、戰(zhàn)后初期西歐經(jīng)濟(jì)的恢復(fù)和發(fā)展
措施:社會改革、調(diào)整政策、利用美援、宏觀指導(dǎo)、發(fā)展科技 典型:德國:原因——政治改革、非軍事化、美國扶持、制定政策、重視科教、人民素質(zhì) 成果——50年代進(jìn)入繁榮時期
60年代初成為歐洲頭號資本主義經(jīng)濟(jì)大國
(二)、歐洲共同體的形成
原因:經(jīng)濟(jì)發(fā)展,西歐國家聯(lián)系密切,開始一體化進(jìn)程 時間:1967年成立
目標(biāo):爭取自由交流,促進(jìn)經(jīng)濟(jì)發(fā)展 影響:政治上——成為威脅美國的新的一極 經(jīng)濟(jì)上——改變資本主義世界經(jīng)濟(jì)格局
(三)歐洲聯(lián)盟的建立 時間:1993年
成員:到2004年25個成員國 總部:布魯塞爾
簡介:統(tǒng)一護(hù)照;統(tǒng)一貨幣;盟旗;盟歌;
主要機(jī)構(gòu):歐洲委員會、歐洲議會、歐洲聯(lián)盟委員會;歐洲法院等; 影響:政治上――力求在外交和國家安全方面步調(diào)一致
經(jīng)濟(jì)上――歐盟成員之間資源共享、優(yōu)勢互補(bǔ),成為世界最大的經(jīng)濟(jì)體
八、布置作業(yè):完成本課三維優(yōu)化之練習(xí)
九、教學(xué)后記:
