表達感情,從小事做起大家好,我們是601班學生沈xx。今天國旗下講話的主題是:表達感情,從小事做起。三月里有三個眾所周知的節(jié)日,那就是婦女節(jié)、雷鋒紀念日和植樹節(jié)。在婦女節(jié)除了給母親獻上一束鮮花以外,還能做什么呢?我了,首先將寫有“媽媽,婦女節(jié)快樂”拴在氣球上,還用小卡片寫上:“i love you”貼在墻上。然后為了讓媽媽更幸福,剪了一些小卡片,準備在媽媽驚喜時來個仙女撒花,讓她喜上加喜。當媽媽下班時,看到這一切,感動的說不出話時,心里別提有多幸福了。我們班的黃宇婷是這樣做的:她將沙發(fā)、床鋪、地面整理清掃了一遍。當她想著媽媽幸福的表情時,陶醉的不小心把膝蓋碰傷了。原來可以用行動感謝媽媽。大家做的都是一些家務事,而我了卻做了媽媽一直想讓我做的事。媽媽說我做的最讓她高興的事就是不半途而廢,不讓她操心。周日,我自己主動起床,自己主動買早餐。看到媽媽欣慰的笑。我開心極了,返校時不忘給媽媽甜甜的來一句:“媽媽節(jié)日快樂?!?/p>
開學第二周國旗講話發(fā)言稿 老師們,同學們:大家好!今天我國旗下演講的題目是《演好自己的角色》。每段時期自己都有屬于自己的角色,天真無邪的童年,懵懵懂懂的少年,輕狂迷茫的青年。可能很多時候你會懷念自己以前的角色,或者想象自己未來的角色,但最重要的是演好你自己現(xiàn)在的角色。因為你只有在自己的角色里才真正有發(fā)言權(quán)。信念要先行行勝于言,但是在行動之前給自己樹立好的心態(tài)更能起到事半功倍的效果。調(diào)整自己,這是不論干什么都要一直進行的一個過程。給自己正確積極的定位,要考慮到外界因素,但也不要被外界環(huán)境壓倒。學會選擇,學會放棄,學會承認自己的弱點,接下來我們就可以在更堅實更廣闊的道路上奔跑?!拔覀儾荒茏笥姨鞖?,但可以改變心情;我們不能選擇容貌,但可以展示笑容;我們不能預知明天,但可以把握今天。”
2.辯證的否定(1)辯證的否定是事物的自我否定。事物內(nèi)部存在著肯定方面和否定方面,它們既對立又統(tǒng)一。最初,肯定方面處于支配地位,否定方面處于被支配地位。在這種情況下,事物就被肯定著。但是,在矛盾雙方的斗爭中,否定方面總會由弱變強。一旦否定方面由被支配地位上升為支配地位,事物就轉(zhuǎn)化到了自己的對立面,實現(xiàn)了對事物的否定。事物最終之所以被否定,根源在于事物的內(nèi)部,是事物內(nèi)部的否定因素戰(zhàn)勝了肯定因素。因此,事物的否定是自我否定。(2)辯證的否定是事物發(fā)展的環(huán)節(jié)和聯(lián)系的環(huán)節(jié)。所謂發(fā)展,是指新事物的產(chǎn)生和舊事物的滅亡。而實現(xiàn)這一過程必須要對舊事物進行否定,否定實現(xiàn)了事物由舊質(zhì)向新質(zhì)的飛躍。新事物在否定舊事物時,并不是把舊事物全盤拋棄,一筆勾銷。舊事物是新事物的母體,新事物從舊事物那里脫胎而來,新事物是在批判地繼承舊事物中的一切積極的有生命力的因素的基礎(chǔ)上發(fā)展起來的。這樣,在新舊事物之間就存在著必然的聯(lián)系。
在數(shù)學上,0這個數(shù)是解決記數(shù)和進位問題而引進的概念,由于它不能表示實在的東西,很長時間人們不把它看作是一個數(shù)。認為0是無,是對有的否定。從唯物辯證法的觀點看,這種否定不是形而上學的簡單否定,而是具有豐富內(nèi)容的辨證否定。辨證的否定是發(fā)展的環(huán)節(jié)。0是從無到有的必經(jīng)之路,是連接無和有的橋梁。0又是正數(shù)和負數(shù)之間的界限,它既否定了任何正數(shù),也否定了任何負數(shù),是唯一的中性數(shù)。但它又是聯(lián)結(jié)正數(shù)和負數(shù)的中間環(huán)節(jié)。沒有0,負數(shù)就過渡不到正數(shù)去,正數(shù)也休想發(fā)展到負數(shù)來。數(shù)學中的0是對任何定量的否定。如果沒有這一否定,任何量的發(fā)展都無從談起。這個否定不是一筆勾銷,而是揚棄。因為它克服了任何定量的有限性,成為其發(fā)展的環(huán)節(jié)。在現(xiàn)實生活中,0作為辨證的否定,也體現(xiàn)出聯(lián)系和發(fā)展的性質(zhì)。如0度不是沒有溫度,而是非常確定的溫度。
三個“二次”即一元二次函數(shù)、一元二次方程、一元二次不等式是高中數(shù)學的重要內(nèi)容,具有豐富的內(nèi)涵和密切的聯(lián)系,同時也是研究包含二次曲線在內(nèi)的許多內(nèi)容的工具 高考試題中近一半的試題與這三個“二次”問題有關(guān) 本節(jié)主要是幫助考生理解三者之間的區(qū)別及聯(lián)系,掌握函數(shù)、方程及不等式的思想和方法。課程目標1. 通過探索,使學生理解二次函數(shù)與一元二次方程,一元二次不等式之間的聯(lián)系。2. 使學生能夠運用二次函數(shù)及其圖像,性質(zhì)解決實際問題. 3. 滲透數(shù)形結(jié)合思想,進一步培養(yǎng)學生綜合解題能力。數(shù)學學科素養(yǎng)1.數(shù)學抽象:一元二次函數(shù)與一元二次方程,一元二次不等式之間的聯(lián)系;2.邏輯推理:一元二次不等式恒成立問題;3.數(shù)學運算:解一元二次不等式;4.數(shù)據(jù)分析:一元二次不等式解決實際問題;5.數(shù)學建模:運用數(shù)形結(jié)合的思想,逐步滲透一元二次函數(shù)與一元二次方程,一元二次不等式之間的聯(lián)系。
②內(nèi)燃機的發(fā)明推動了交通運輸領(lǐng)域的革新。19世紀末,新型的交通工具——汽車出現(xiàn)了。1885年,德國人卡爾·本茨成功地制成了第一輛用汽油內(nèi)燃機驅(qū)動的汽車。1896年,美國人亨利·福特制造出他的第一輛四輪汽車。與此同時,許多國家都開始建立汽車工業(yè)。隨后,以內(nèi)燃機為動力的內(nèi)燃機車、遠洋輪船、飛機等也不斷涌現(xiàn)出來。1903年,美國人萊特兄弟制造的飛機試飛成功,實現(xiàn)了人類翱翔天空的夢想,預告了交通運輸新紀元的到來。③內(nèi)燃機的發(fā)明推動了石油開采業(yè)的發(fā)展和石油化學工業(yè)的產(chǎn)生。石油也像電力一樣成為一種極為重要的新能源。1870年,全世界開采的石油只有80萬噸,到1900年猛增至2 000萬噸。(3)化學工業(yè)的發(fā)展:①無機化學工業(yè):用化學反應的方式開始從煤焦油中提煉氨、笨、等,用化學合成的方式,美國人發(fā)明了塑料,法國人發(fā)明了纖維,瑞典人發(fā)明了炸藥等。

五月的時光在不知不覺間流逝,六月的陽光將照耀在我們的臉上。天真的笑臉,歡快的笑聲,明天我們將迎來六一國際兒童節(jié)。 目前,各國政府普遍關(guān)注兒童的未來,保護兒童的權(quán)益。聯(lián)合國1990年通過的《兒童權(quán)利公約》,我國是參與制定國和簽約國之一。在批準《兒童權(quán)利公約》的同一年,我國頒布了《中華人民共和國未成年人保護法》,這對維護少年兒童的權(quán)益起到了積極的作用?!傲弧笔俏覀冏羁鞓返墓?jié)日,因為: 我們是家庭的寶貝,更是家庭的希望。你們能夠快樂地成長,家庭就充滿歡歌與笑語。我們是學校的學生,更是學校的希望。我們能夠全面地發(fā)展,學校就充滿生機與活力。我們是社會的未來,更是社會的希望。我們能夠和諧地發(fā)展,社會就充滿熱情與友愛。
老師們,同學們,大家好!我是××班的××,今天,非常榮幸站在國旗下,發(fā)表我的觀點,我要講話的主題是:“獨立”與“合作”。大家都很熟悉《眾人劃槳開大船》這首歌吧,其中有一句歌詞是這樣寫的:“一支竹篙,難渡汪洋海;眾人劃槳,開動大帆船?!边@首歌就很形象的告訴了我們:在需要“合作”的時候,就不能“獨立”,當然反過來說,我們也可以理解,在需要“獨立”的時候,就應當獨立起來,要想成為一名優(yōu)秀的學生,就應當真正處理好獨立學習與合作學習的關(guān)系。在我們進入學校的時候,老師就一再跟我們強調(diào),在學習當中,我們首先應該學會“獨立”:獨立選擇,獨立思考,獨立領(lǐng)悟,最后獨立解決問題。這也正體現(xiàn)了“獨立”的價值。獨立是必須的,但是每當在學習上碰到了困難,遇到了讓你解決不了的問題,這個時候就要放棄獨立,學會合作,要與同學的合作、與老師的合作:討論、傾聽、解答,這是在解決問題中行之有效的方法。合作,可以共同解決疑問,共享學習成果,促進我們思維的發(fā)展。不只在學習中,其實娛樂當中,在生活當中,也需要有“獨立”與“合作”的表現(xiàn)。就拿上次校運會中的接力賽來說吧,在這個比賽項目中,我們班取得了令人可喜的好成績。比賽場上,50位同學要各自獨立地完成好自己的賽程。在自己所擁有的這段賽程上,定要竭盡全力地發(fā)揮出自己的實力,在數(shù)千人面前好好表現(xiàn)自己。
環(huán)節(jié)四 課堂總結(jié) 鞏固知識本節(jié)課我采用線索性的板書,整個知識結(jié)構(gòu)一目了然,為了充分發(fā)揮學生在課堂的主體地位,我將課堂小結(jié)交由學生完成,請學生根據(jù)課堂學習的內(nèi)容,結(jié)合我的板書設(shè)計來進行小結(jié),以此來幫助教師在第一時間掌握學生學習信息的反饋,同時培養(yǎng)學生歸納分析能力、概括能力。環(huán)節(jié)五 情景回歸,情感升華我的實習指導老師告訴過我們,政治這一門學科要從生活中來到生活去,所以在課堂的最后布置課外作業(yè),以此培養(yǎng)學生對理論的實際運用能力,同時檢驗他們對知識的真正掌握情況,以此達到情感的升華,本節(jié)課,我根據(jù)建構(gòu)主義理論,強調(diào)學生是學習的中心,學生是知識意義的主動建構(gòu)者,是信息加工的主體,要強調(diào)學生在課堂中的參與性、以及探究性,不僅讓他們懂得知識,更讓他們相信知識,并且將知識融入到實踐當中去,最終達到知、情、意、行的統(tǒng)一。
感觸之二:要深刻理解每一條款的內(nèi)在要求 關(guān)于學習員工守則的方式方法,尤其是經(jīng)過了二級分行舉辦的“學守則、遵規(guī)章”合規(guī)知識競賽的檢驗,個人認為要學好守則,必須做到一是對守則的條款要理解性記憶,不可死記硬背。能記憶并熟知守則的條款內(nèi)容是貫徹落實好守則的前提,雖然不能排除極少數(shù)人有超人的記憶能力的可能,但絕大多數(shù)人的記憶能力都差不多,所以我們在記憶時要充分理解每一個條款,抓住關(guān)鍵字詞記憶,如勤勉盡職部分,我們應知道勤勉盡職在守則中體現(xiàn)的就是“制度要求、專業(yè)水準、工作效率以及禁止性規(guī)定”,堅持專業(yè)水準當然要加強學習,不斷提高;提高工作效率當然要科學管理時間,不相互扯皮等;二是要聯(lián)系記憶。即把守則中倡導我們作什么,禁止我們做什么聯(lián)系起來,找出不同要求間的深層的聯(lián)系,如關(guān)于員工在工作中如何做到依法合規(guī)方面,可以提煉出“倡導我們牢固樹立法律意識和合規(guī)意識,禁止任何以違規(guī)為代價的追求利益行為”,這樣對整個依法合規(guī)部分的記憶就會容易些;
(一)例題引入籃球聯(lián)賽中,每場比賽都要分出勝負,每隊勝1場得2分,負1場得1分。某隊在10場比賽中得到16分,那么這個隊勝負場數(shù)分別是多少?方法一:(利用之前的知識,學生自己列出并求解)解:設(shè)剩X場,則負(10-X)場。方程:2X+(10-X)=16方法二:(老師帶領(lǐng)學生一起列出方程組)解:設(shè)勝X場,負Y場。根據(jù):勝的場數(shù)+負的場數(shù)=總場數(shù) 勝場積分+負場積分=總積分得到:X+Y=10 2X+Y=16

The topic of this part is “Write about your festival experience”.During the Listening and Speaking and Talking, students are just asked to say out their festival experiences such as the Spring Festival, Mid-autumn Day, but this part students will be asked to write down their own festival experiences. During the reading part, it introduces the Naadam Festival in Inner Mongolia Autonomous Region, which can give students a good example to imitate. Students not only learn the festival, but touch and feel the Inner Mongolian’s character, the spirit and cultural atmosphere, which can help students form the cultural awareness and learn to enjoy and value the diversity of Chinese culture.Concretely, the dairy tells the experience that the author spent the Naadam Festival in Inner Mongolia Autonomous Region with his/her friend. The structure is clear. In the opening paragraph, it introduces the topic of the Naadam Festival and the whole feeling. Then it introduces the items of the festival like the ceremony, wrestling and horse racing. Finally, it summarizes this experience. Because this part is a travel journal, we must guide students pay more attention to these details: 1. use the first person. 2. use the past tense to tell the past thing and use the present or future tense to describe the scenery. 3. use the timeline to tell the development. 4. be careful for the author’s psychology, emotion and feeling, etc.1.

另一方面,其余的人反對這個計劃,因為它可能會導致一些不好的影響。7.I hold the belief that space exploration not only enable us to understand how the universe began but also help us survived well into the future.我堅信探索太空不僅能夠使我們了解宇宙的起源而且能夠幫助我們更好地走進未來。8.I think we should spend more time and money exploring space so as to provide new and better solutions to people's shortterm and longterm problems.為了給人類的短期和長期問題提供更新和更好的解決方法,我認為我們應該花更多的時間和金錢來探索太空。9.From my point of view,it is wrong of young people to depend on their telephones too much,which may do harm to both their physical and mental health.在我看來,年輕人過度依賴手機是不對的,因為它們可能會對他們的身心健康都有害。最近你班同學就“人類是否應該進行宇宙探索”這個問題進行了激烈的討論。有人認為,探索宇宙不僅讓人類更好地了解宇宙的發(fā)展,還可以用來指導農(nóng)業(yè)生產(chǎn),以及把一些探索太空的高新技術(shù)用于現(xiàn)實生活;也有一些人認為探索太空花掉了大量的人力物力;影響了人們的生活水平。請你根據(jù)以下情況寫一篇報告并發(fā)表自己的觀點。注意:1.寫作內(nèi)容應包括以上全部要點,可適當發(fā)揮,使上下文連貫;
Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.
