第十周國旗下講話稿：愛國
老師們、同學(xué)們：早上好，我今天講話的主題就是愛國。天下興亡匹夫有責(zé)，位卑未敢忘國。我們每個(gè)人都與國家休戚與共。每周一當(dāng)我們站在這里，唱著雄壯激昂的國歌，目睹著五星紅旗冉冉升起，高呼國家的利益高于一切時(shí)，在這種莊嚴(yán)肅穆的氛圍中，我們的國家意識(shí)越來越強(qiáng)。這是愛國主義教育的一部分。其實(shí)古今中外無論哪一個(gè)國家都以愛國主義為凝結(jié)的風(fēng)氣,動(dòng)員和激勵(lì)人們團(tuán)結(jié)起來。我們來看看一些發(fā)達(dá)國家是怎樣做的。美國孩子從幼兒園開始就要學(xué)習(xí)畫國旗、唱國歌。一上小學(xué)，每天早晨，都要參加唱國歌、升國旗儀式，把右手放在左胸前，宣誓效忠國家。美國籃球、橄欖球或棒球等重大體育賽事，都有一個(gè)保留節(jié)目，就是在開場(chǎng)前全場(chǎng)起立，由著名歌手領(lǐng)唱美國國歌。還有我們熟悉的美國電影也帶有很濃厚的愛國色彩，好萊塢的許多大片都在向世界宣揚(yáng)“美國精神”，夸張得渲染美國有多厲害。再看看日本，日本目前有許多學(xué)校正積極推行二戰(zhàn)前的愛國思想教育，老師們還在成績(jī)單上分A、B、c給學(xué)生們打“愛國分”。日本的新歷史教科書在涉及鄰國及侵華戰(zhàn)爭(zhēng)的重大歷史問題，總是上極盡歪曲、篡改。

第十一周的國旗下講話
發(fā)揚(yáng)成績(jī)，再接再厲，爭(zhēng)取更大進(jìn)步歲月匆匆。開學(xué)的情景似乎還在眼前，只是轉(zhuǎn)瞬之間，半個(gè)學(xué)期已經(jīng)過去?；仡櫚雽W(xué)期來，全體同學(xué)在老師的辛勤教育下，發(fā)奮努力，在各方面取得了長足的進(jìn)步，這是令人高興的。我們學(xué)校的校風(fēng)是“養(yǎng)成良好的習(xí)慣”。這習(xí)慣是多方面的。首先，是必須具備良好的道德情操，樹立良好的精神風(fēng)貌。為此，學(xué)校開展了豐富多彩的活動(dòng)。如八項(xiàng)流動(dòng)紅旗的評(píng)比，對(duì)各年級(jí)獲得流動(dòng)紅旗和評(píng)比前三名的優(yōu)勝班級(jí)，在每周的升旗儀式時(shí)通報(bào)表揚(yáng)。為繼承先烈精神，發(fā)揚(yáng)光榮傳統(tǒng)，學(xué)校組織了祭掃烈士墓、祭掃葉圣陶先生墓的活動(dòng)。春天，正是草木茂密生長的季節(jié)，為了讓校園里花更艷、草更綠，同學(xué)們自愿參與紅領(lǐng)巾愛綠護(hù)綠的活動(dòng)，發(fā)揮了小主人的作用?！吧r(nóng)場(chǎng)”是葉圣陶先生留給我校的寶貴的教育財(cái)富，學(xué)校為了弘揚(yáng)葉圣陶的育人思想，不但在校園內(nèi)開辟了實(shí)驗(yàn)基地，還在淞南村的生態(tài)農(nóng)莊內(nèi)建立校外“生生農(nóng)場(chǎng)”。為讓學(xué)生在活動(dòng)中經(jīng)受鍛煉，體會(huì)農(nóng)耕的辛勞，二、三、四年級(jí)四個(gè)專題班級(jí)的學(xué)生步行來到校外生生農(nóng)場(chǎng)——開展了社會(huì)綜合實(shí)踐活動(dòng)。

講話稿有廣義和狹義之分。廣義的講話稿是人們?cè)谔囟▓?chǎng)合發(fā)表講話的文稿；狹義的講話稿即一般所說的領(lǐng)導(dǎo)講話稿，是各級(jí)領(lǐng)導(dǎo)在各種會(huì)議上發(fā)表帶有宣傳、指示、總結(jié)，下面是小編整理的第十周國旗下講話稿，歡迎來參考！篇一：第十周國旗下講話稿 老師們，同學(xué)們：早上好！今天我演講的題目是：認(rèn)真復(fù)習(xí)準(zhǔn)備，迎接期中考試。五一小長假結(jié)束了，半個(gè)學(xué)期也悄然而逝，我們即將面臨期中考試。同學(xué)們應(yīng)科學(xué)的制定自己的學(xué)習(xí)計(jì)劃，使復(fù)習(xí)工作有秩序的進(jìn)行，達(dá)到事半功倍的效果。孔子說過“學(xué)而時(shí)習(xí)之，不亦說乎？”意思是學(xué)了新知識(shí)，然后有計(jì)劃的按時(shí)去復(fù)習(xí)，也是一件快樂的事情。心理學(xué)研究表明，遺忘是必然的，世上從來就沒有真正過目不忘的人，已經(jīng)學(xué)過的知識(shí)需要不斷地、重復(fù)的記憶，才能使知識(shí)在大腦里留下深深地印痕。著名的橋梁專家茅以升記憶力超人，曾經(jīng)有很多人向他詢問他的記憶秘訣，他回答說：說起來也簡(jiǎn)單，就是重復(fù)！重復(fù)！再重復(fù)！學(xué)過的東西，只有反復(fù)復(fù)習(xí)，才能牢固的記憶，并且能夠應(yīng)用自如。由此可見，復(fù)習(xí)對(duì)每位同學(xué)都顯得尤為重要。
工作總結(jié)寫作，貴在不斷創(chuàng)新
一、實(shí)現(xiàn)總匯總攬 在進(jìn)行“總”時(shí)，要提高認(rèn)識(shí)的深度，實(shí)現(xiàn)情況總匯到情況總攬的轉(zhuǎn)變。情況總匯，要求把各種情況了解得全面而豐富，似乎一天也說不完；情況總攬，就是要準(zhǔn)確掌握情況中的關(guān)鍵和要害，用一兩句話把情況說清楚、講明白。 在“總”的過程中，總匯是寫作的基礎(chǔ)，需要花時(shí)間、下功夫；總攬是寫作的升華，需要有智慧、拼能力，這種智慧和能力，就是總體駕馭、宏觀把握、提綱挈領(lǐng)的能力。 ，：總結(jié)工作業(yè)績(jī)時(shí)，要把情況說清楚，做到心中有數(shù)。既要讓人知道你干了什么，又要讓人明白你是怎么干的，工作中有什么亮點(diǎn)，有什么經(jīng)驗(yàn)值得推廣。這就需要在“講清楚、說明白”上下很大的功夫。 要學(xué)會(huì)跳出局外進(jìn)行對(duì)照和比較，弄清楚哪些是真正的亮點(diǎn)和成績(jī)，哪些是主要的問題和不足，哪些事情比較大需要大寫特寫，哪些事情比較小或者根本不重要，不需要寫或者只需要一筆帶過。這樣才能做到重點(diǎn)突出、詳略得當(dāng)、有輕有重。

新知探究前面我們研究了兩類變化率問題：一類是物理學(xué)中的問題，涉及平均速度和瞬時(shí)速度；另一類是幾何學(xué)中的問題，涉及割線斜率和切線斜率。這兩類問題來自不同的學(xué)科領(lǐng)域，但在解決問題時(shí)，都采用了由“平均變化率”逼近“瞬時(shí)變化率”的思想方法；問題的答案也是一樣的表示形式。下面我們用上述思想方法研究更一般的問題。探究1： 對(duì)于函數(shù)y=f(x) ，設(shè)自變量x從x_0變化到x_0+ ?x ，相應(yīng)地，函數(shù)值y就從f(x_0)變化到f(〖x+x〗_0) 。這時(shí)， x的變化量為?x，y的變化量為?y=f(x_0+?x)-f(x_0)我們把比值?y/?x，即?y/?x=(f(x_0+?x)-f(x_0)" " )/?x叫做函數(shù)從x_0到x_0+?x的平均變化率。1．導(dǎo)數(shù)的概念如果當(dāng)Δx→0時(shí)，平均變化率ΔyΔx無限趨近于一個(gè)確定的值，即ΔyΔx有極限，則稱y＝f (x)在x＝x0處____，并把這個(gè)________叫做y＝f (x)在x＝x0處的導(dǎo)數(shù)(也稱為__________)，記作f ′(x0)或________，即

⑦在我看來, 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand，70% think space is worth exploring because we have benefited a lot from it，such as using satellites for communication and weather forecast. What’s more，with further space research，we may solve the population problem by moving to other planets one day. Also，space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner.

The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3. Students can learn related sentences or phrases to express their curiosity like “ I wish to know...” “I’d love to know...”4. Students can learn more about the space and astronauts, even be interested in working hard to be an astronaut

二、相對(duì)論的創(chuàng)立【課件】展示下列材料艾伯特·愛因斯坦（1879——1955），1879年3月14日誕生在德國烏爾姆的一個(gè)猶太人家中。1894年舉家遷居意大利米蘭。1900年畢業(yè)于瑞士蘇黎世工業(yè)大學(xué)。愛因斯坦被認(rèn)為是最富于創(chuàng)造力的科學(xué)家，他不但創(chuàng)立了相對(duì)論，還提出了光量子的概念，得出了光電效應(yīng)的基本定律，并揭示了光的波粒二重性本質(zhì)，為量子力學(xué)的建立奠定基礎(chǔ)。為此榮獲1921年度的諾貝爾物理學(xué)獎(jiǎng)。同時(shí)，他還證明了熱的分子運(yùn)動(dòng)論，提出了測(cè)定分子大小的新方法?！締栴}】19世紀(jì)末20世紀(jì)初愛因斯坦對(duì)物理學(xué)的貢獻(xiàn)是什么？意義是什么？為什么會(huì)出現(xiàn)？1、背景：經(jīng)典物理學(xué)的危機(jī)。19世紀(jì)末三大發(fā)現(xiàn)：x射線、放射性和電子，經(jīng)典力學(xué)無法解釋研究中的新問題，如：黑體輻射、光電效應(yīng)等。2、相對(duì)論的提出及主要內(nèi)容：（1）“狹義相對(duì)論”和光速不變?cè)恚?905年提出。

什么因素可以阻止種群間基因交流呢？由此可引出隔離的概念。學(xué)生初步理解隔離的概念之后，可以安排學(xué)生討論隔離的各種可能的方式，教師歸納出隔離的類型。然后組織學(xué)生閱讀分析教材中的“資料分析”，組織討論“資料分析”中提出的幾個(gè)問題。最后教師應(yīng)強(qiáng)調(diào)，一般情況下，地理隔離是生殖隔離的先決條件，生殖隔離一旦形成，原來屬于一個(gè)物種的兩個(gè)種群，就成了兩個(gè)物種。關(guān)于“共同進(jìn)化與生物多樣性的形成”內(nèi)容的教學(xué)，可以學(xué)生自學(xué)為基礎(chǔ)，教師提出一些具有啟發(fā)性的問題，師生共同歸納總結(jié)的方式推進(jìn)教學(xué)過程。使學(xué)生理解共同進(jìn)化的含義，無機(jī)環(huán)境的變化、無機(jī)環(huán)境的復(fù)雜化和多樣化、有性生殖的出現(xiàn)和生態(tài)系統(tǒng)結(jié)構(gòu)的復(fù)雜化和多樣化對(duì)生物多樣性形成的作用。最后，組織學(xué)生討論生物進(jìn)化理論在發(fā)展。

一,說教材1. 教材的地位和作用本章課程的核心是介紹現(xiàn)代生物進(jìn)化理論.生物進(jìn)化理論的發(fā)展和其他科學(xué)理論的發(fā)展一樣,不是簡(jiǎn)單的新理論對(duì)舊理論的否定和排斥,而是新理論對(duì)舊理論的修正,深入和擴(kuò)展.從拉馬克的進(jìn)化學(xué)說到達(dá)爾文的自然選擇學(xué)說,以及現(xiàn)代進(jìn)化理論的由來,大體都走過了這樣的軌跡.這些應(yīng)該成為處理本節(jié)教學(xué)內(nèi)容的基本脈絡(luò).本節(jié)內(nèi)容包括:拉馬克的進(jìn)化學(xué)說,達(dá)爾文的自然選擇學(xué)說和達(dá)爾文以后生物進(jìn)化理論的發(fā)展,其中重點(diǎn)是達(dá)爾文的自然選擇學(xué)說.生物進(jìn)化論不僅是生物學(xué)中具有重要地位的基礎(chǔ)理論,也是對(duì)人們的自然觀和世界觀有著重要影響的理論.學(xué)生通過本章內(nèi)容的學(xué)習(xí),不僅可以了解生物進(jìn)化理論在達(dá)爾文之后的發(fā)展,進(jìn)一步樹立生物進(jìn)化的觀點(diǎn)和辯證唯物主義觀點(diǎn),而且能夠通過學(xué)習(xí)進(jìn)化理論的發(fā)展過程,加深對(duì)科學(xué)本質(zhì)的理解和感悟.

活動(dòng)一:課本第三頁的活動(dòng)題,把學(xué)生分成幾組然后讓他們讀圖討論,思考書上的幾個(gè)問題,最后派個(gè)代表回答問題.最后教師做適當(dāng)?shù)难a(bǔ)充:人口的自然增長不僅與人口自然增長率有關(guān)，而且還與人口基數(shù)有關(guān).活動(dòng)二:課本第七頁的活動(dòng),先讓兩位學(xué)生閱讀第六頁的案例結(jié)合活動(dòng)題思考問題,讓幾個(gè)組學(xué)生討論所給的幾個(gè)問題.讓學(xué)生歸納最后教師做適當(dāng)?shù)难a(bǔ)充.時(shí)間安排:由于本節(jié)內(nèi)容不難因此整個(gè)教學(xué)過程是一節(jié)課的時(shí)間來完成的因此在教學(xué)過程中注意時(shí)間的把握,在做活動(dòng)和討論時(shí)注意把握時(shí)間,自己盡量少說廢話.課堂小結(jié)通過這一節(jié)的學(xué)習(xí)，同學(xué)們正確理解和認(rèn)識(shí)人口增長,增長模式和人口增長模式的轉(zhuǎn)變。我們可以利用比較法、分析法來掌握，并聯(lián)系現(xiàn)實(shí)生活，進(jìn)行分析、判斷，化理論知識(shí)于實(shí)踐之中。
