一、教材分析? 本節(jié)課是三年級第六單元第一節(jié)的教學(xué)內(nèi)容,主要講了明白什么是分數(shù),初步理解分數(shù)的意義,能正確地認、讀、寫簡單的的分數(shù)等知識。這部分內(nèi)容是在學(xué)生們掌握了一些整數(shù)知識的基礎(chǔ)上來學(xué)習(xí)的,它為進一步學(xué)習(xí)比較分數(shù)的大小和分數(shù)的加減運算有重要的鋪墊作用。? 三年級的學(xué)生活潑好動、思維敏捷、善于學(xué)習(xí),愛好展示,善于發(fā)言,課堂根據(jù)學(xué)生的年齡特點設(shè)計教學(xué)活動?! 《?、教學(xué)目標(針對新課標的要求與教材內(nèi)容,我制定了如下的教學(xué)目標)????? 1、讓學(xué)生理解分數(shù)的意義,能正確地認、讀、寫簡單的分數(shù)。????? 2、能熟練地根據(jù)圖表表示分數(shù),根據(jù)分數(shù)涂寫表格。? 3、培養(yǎng)學(xué)生的思維能力和運用數(shù)學(xué)知識解決實際問題的能力,從而培養(yǎng)學(xué)生學(xué)習(xí)數(shù)學(xué)的興趣。????? 三、教學(xué)重點難點 對教學(xué)目標和教材內(nèi)容,我確定了教學(xué)重點和難點)???正確地認、讀、寫簡單的分數(shù)以及初步認識分數(shù)的含義是重點。???合作探究理解分數(shù)的意義是難點。
可愛的同學(xué)們、可敬的老師們:大家好! 結(jié)束了愉快的暑假生活,今天我們又聚集在xx小學(xué)校園里,迎接最有希望和生機的XX學(xué)年第一學(xué)期。今天是新一學(xué)期開學(xué)的第一天,我們在這里舉行新學(xué)期升旗儀式,借此機會,我代表咱們學(xué)校,向全校師生致以最誠摯的祝福,祝全體同學(xué)和老師在新的一學(xué)期里身心健康、工作順利、學(xué)習(xí)進步、夢想成真。 本學(xué)期,有六位新老師和一年級六十六位新同學(xué)加入了xx小學(xué)這個大家庭,請大家用熱烈的掌聲,對新老師和新同學(xué)表示最熱烈的歡迎! 過去的一學(xué)年,在全體師生的共同努力下,學(xué)校取得了不少成績,獲得了不少榮譽。這是全體學(xué)生刻苦努力、勤奮學(xué)習(xí)的結(jié)果,更是老師們辛勤耕耘、用心澆灌的結(jié)果,它必將鼓舞我們滿懷信心、昂首闊步踏上新學(xué)年的陽光大道! 同學(xué)們,面對徐徐升起的五星紅旗,你們在想什么呢?作為一個小學(xué)生,如何使自己成為家庭的好孩子、學(xué)校的好學(xué)生、社會的好少年呢?將來如何更好地適應(yīng)新形勢的需求,把自己塑造成為符合時代發(fā)展的、能為社會作貢獻的人才呢?
老師們、同學(xué)們:早上好!今天我國旗下演講的題目是《珍愛生命,遠離毒品》。我們對于毒品一直很痛恨,但并不是人人都做到了自覺地抵制毒品、自覺地遠離毒品、自覺地與吸毒現(xiàn)象作斗爭。在現(xiàn)實生活中,就存在有很多吸毒、涉毒、販毒的現(xiàn)象,許多美好的生命就在毒品中消亡。據(jù)公安機關(guān)不完全統(tǒng)計,全國有在冊的吸毒者將近100萬,近100萬人中,70-80%是35歲以下的青年,而青少年已成為最易受到毒品侵害的高危人群。青少年吸毒,嚴重摧殘身心健康。青少年身心尚未發(fā)育成熟,一旦吸毒,很容易成癮,一旦成癮,就會導(dǎo)致記憶力衰退,營養(yǎng)不良,抵抗力明顯下降,各種疾病發(fā)生,慢慢走向死亡。青少年吸毒不但給自身帶來極大危害,而且造成家破人亡,甚至破壞社會風(fēng)氣,危害社會治安,引發(fā)刑事案件,影響和諧穩(wěn)定。
北冥有魚,其名曰鯤。鯤之大,不知其幾千里也;化而為鳥,其名為鵬。鵬之背,不知其幾千里也;怒而飛,其翼若垂天之云。是鳥也,海運則將徙于南冥,南冥者,天池也?!洱R諧》者,志怪者也?!吨C》之言曰:“鵬之徙于南冥也,水擊三千里,摶扶搖而上者九萬里,去以六月息者也?!币榜R也,塵埃也,生物之以息相吹也。
一般來說,人的天性是習(xí)慣于得到、而不習(xí)慣于失去的。呱呱墜地,我們首先得到了生命,自此以后,我們不斷地得到:從父母得到衣食、玩具、愛和托育,從社會得到職業(yè)的說練和文化的培養(yǎng)。長大成人以后,我們靠著自然的傾向和自己的努力繼續(xù)得到:得到愛情、配偶和孩子,得到金錢、財產(chǎn)、名譽、地位,得到事業(yè)的成功和社會的承認,如此等等。

因徐校長退休,上個星期我來到了學(xué)校,又成為了東山實驗小學(xué)的一員,擔(dān)任校長工作。我姓吳,以后大家可以叫我吳校長或吳老師。在13年前,我就是我們學(xué)校的數(shù)學(xué)老師。在這里我工作了整整20年,我的兒子也是在本校畢業(yè)。這是一所了不起的小學(xué),是XX省首批辦好的老牌實驗小學(xué),也是XX省“模范學(xué)?!?。這是一所辦學(xué)近200年的學(xué)校,多少年來為中學(xué)輸送了一批批優(yōu)秀的畢業(yè)生,為生國家培養(yǎng)了一大批優(yōu)秀的人才,院士、科學(xué)家等數(shù)以百計。我的兒子后來也考取了北京大學(xué),現(xiàn)在國家公派在國外留學(xué)。我說兒子并不是自我夸耀,而是想告訴同學(xué)們一點,能在東山實驗小學(xué)學(xué)習(xí)與工作是幸福的、光榮的。因為,東山實驗小學(xué)有一個個關(guān)愛你們,為同學(xué)們的獲得良好的學(xué)習(xí)成長、優(yōu)良的品德形成,健康的身心發(fā)展的敬業(yè)、愛崗、樂于奉獻的老師。在此我建議,讓我們用最熱烈的掌聲向老師們表示最衷心的感謝!
Step 3 Analyzing article structureActivity 31. Teachers raise questions to guide students to analyze the chapter structure of this diary and think about how to describe the festival experience. (1)What should be included in the opening/body/closing paragraph(s)?(2)How did the writer arrange his/her ideas?(3)What kind of interesting details did the writer describe?(4)How did the writer describe his/her feelings/emotions during the event?2. Students read and compare the three sentence patterns in activity 2. Try to rewrite the first paragraph of the diary with these three sentence patterns. After that, students exchange corrections with their partners. Such as:●This was my first time spending three days experiencing the Naadam Festival in China’s Inner Mongolia Autonomous Region and it was an enjoyable and exciting experience. ●I'll never forget my experience at the Naadam Festival because it was my first time to watch the exciting Mongolian games of horse racing, wrestling, and archery so closely. ●I'll always remember my first experience at the Naadam Festival in China’s Inner Mongolia Autonomous Region because it was so amazing to spend three days witnessing a grand Mongolian ceremony. Step 4 Accumulation of statementsActivity 41. Ask the students to read the diary again. Look for sentences that express feelings and emotions, especially those with the -ing form and the past participle. Such as:● …h(huán)orse racing, wrestling, and archery, which are all so exciting to watch. ● some amazing performances● I was surprised to see…● I was a little worried about. . . ● feeling really tiredOther emotional statements:●I absolutely enjoyed the archery, too, but the horse races were my favourite part. ●I'm finally back home now, feeling really tired, but celebrating Naadam with my friend was totally worth it. ●He invited me back for the winter to stay in a traditional Mongolian tent and cat hot pot. I can’t wait!2. In addition to the use of the -ing form and the past participle, the teacher should guide the students in the appreciation of these statements, ask them to memorize them, and encourage them to use them reasonably in writing practice.
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
The theme of this unit focuses on “space exploration.” Students will learn about the training and experience needed to become an astronaut. The text is mainly about the development of space exploration. On the one hand, the text helps students to have a good understanding about the great feats humans have achieved, on the other hand, they will further understand the contributions that we Chinese have achieved, and feel confident and proud about our homeland and strengthen their love for our country. The teacher should instruct students to aim high and study harder to make great progress in the space career if possible.1. Read about the development and value of space exploration.2. Explore the mysteries of the universe and the achievements in space exploration.3. Skillfully use the vocabulary of this text to cultivate self-study ability 4. Develop cooperative learning ability through discussion.1. Enable the Ss to talk about the development and value of space exploration.2. Guide the Ss to summarize the main idea of each paragraph as well as the main idea of the text.3. Help Ss comprehend the main reasons for space exploration. Multi-media, textbook, notebooks.Step 1: Warming up and predictionLook at the title and the pictures of the text and predict what the text will be about?2. What are the main reasons for space exploration?
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.

二是以ZT教育聚力引領(lǐng)服務(wù)。組建“走出去”的D員先鋒隊,在集團安全生產(chǎn)、防汛搶險、防凍抗暑、為民解難等一系列急、難、險、重工作中沖在前,勇于挺身而出,敢于打硬仗,切實推動D建引領(lǐng)下的社會治理和為民服務(wù)工作取得實效。三、ZT教育存在的不足及下步打算盡管國企(集團)D委的2023年ZT教育取得了初步的成效,但還存在著一些不足需要加強改進。一是學(xué)習(xí)形式還不夠豐富。目前,還未全面開展D員領(lǐng)導(dǎo)干部到聯(lián)系支部講DK、“聽老D員講DK”“誦讀悟思想”等活動。二是在工作開展中缺乏特色做法。只按照﹡﹡主題辦工作任務(wù)清單開展學(xué)習(xí)教育,與集團亮點工作結(jié)合較少,缺乏特色、創(chuàng)新。接下來,國企(集團)D委將緊扣2023年ZT教育階段要求、步驟安排、規(guī)定動作,嚴把標準關(guān)、質(zhì)量關(guān),進一步加大統(tǒng)籌協(xié)調(diào)、宣傳引導(dǎo),推出集團特色做法,特別是圍繞第一批ZT教育“收官階段”經(jīng)驗總結(jié)和重點難點工作突破,不斷推進2023年ZT教育取得新進展新突破。
探究新知問題1:已知100件產(chǎn)品中有8件次品,現(xiàn)從中采用有放回方式隨機抽取4件.設(shè)抽取的4件產(chǎn)品中次品數(shù)為X,求隨機變量X的分布列.(1):采用有放回抽樣,隨機變量X服從二項分布嗎?采用有放回抽樣,則每次抽到次品的概率為0.08,且各次抽樣的結(jié)果相互獨立,此時X服從二項分布,即X~B(4,0.08).(2):如果采用不放回抽樣,抽取的4件產(chǎn)品中次品數(shù)X服從二項分布嗎?若不服從,那么X的分布列是什么?不服從,根據(jù)古典概型求X的分布列.解:從100件產(chǎn)品中任取4件有 C_100^4 種不同的取法,從100件產(chǎn)品中任取4件,次品數(shù)X可能取0,1,2,3,4.恰有k件次品的取法有C_8^k C_92^(4-k)種.一般地,假設(shè)一批產(chǎn)品共有N件,其中有M件次品.從N件產(chǎn)品中隨機抽取n件(不放回),用X表示抽取的n件產(chǎn)品中的次品數(shù),則X的分布列為P(X=k)=CkM Cn-kN-M CnN ,k=m,m+1,m+2,…,r.其中n,N,M∈N*,M≤N,n≤N,m=max{0,n-N+M},r=min{n,M},則稱隨機變量X服從超幾何分布.
2.某小組有20名射手,其中1,2,3,4級射手分別為2,6,9,3名.又若選1,2,3,4級射手參加比賽,則在比賽中射中目標的概率分別為0.85,0.64,0.45,0.32,今隨機選一人參加比賽,則該小組比賽中射中目標的概率為________. 【解析】設(shè)B表示“該小組比賽中射中目標”,Ai(i=1,2,3,4)表示“選i級射手參加比賽”,則P(B)= P(Ai)P(B|Ai)= 2/20×0.85+ 6/20 ×0.64+ 9/20×0.45+ 3/20×0.32=0.527 5.答案:0.527 53.兩批相同的產(chǎn)品各有12件和10件,每批產(chǎn)品中各有1件廢品,現(xiàn)在先從第1批產(chǎn)品中任取1件放入第2批中,然后從第2批中任取1件,則取到廢品的概率為________. 【解析】設(shè)A表示“取到廢品”,B表示“從第1批中取到廢品”,有P(B)= 112,P(A|B)= 2/11 ,P(A| )= 1/11所以P(A)=P(B)P(A|B)+P( )P(A| )4.有一批同一型號的產(chǎn)品,已知其中由一廠生產(chǎn)的占 30%, 二廠生產(chǎn)的占 50% , 三廠生產(chǎn)的占 20%, 又知這三個廠的產(chǎn)品次品率分別為2% , 1%, 1%,問從這批產(chǎn)品中任取一件是次品的概率是多少?
3.某縣農(nóng)民月均收入服從N(500,202)的正態(tài)分布,則此縣農(nóng)民月均收入在500元到520元間人數(shù)的百分比約為 . 解析:因為月收入服從正態(tài)分布N(500,202),所以μ=500,σ=20,μ-σ=480,μ+σ=520.所以月均收入在[480,520]范圍內(nèi)的概率為0.683.由圖像的對稱性可知,此縣農(nóng)民月均收入在500到520元間人數(shù)的百分比約為34.15%.答案:34.15%4.某種零件的尺寸ξ(單位:cm)服從正態(tài)分布N(3,12),則不屬于區(qū)間[1,5]這個尺寸范圍的零件數(shù)約占總數(shù)的 . 解析:零件尺寸屬于區(qū)間[μ-2σ,μ+2σ],即零件尺寸在[1,5]內(nèi)取值的概率約為95.4%,故零件尺寸不屬于區(qū)間[1,5]內(nèi)的概率為1-95.4%=4.6%.答案:4.6%5. 設(shè)在一次數(shù)學(xué)考試中,某班學(xué)生的分數(shù)X~N(110,202),且知試卷滿分150分,這個班的學(xué)生共54人,求這個班在這次數(shù)學(xué)考試中及格(即90分及90分以上)的人數(shù)和130分以上的人數(shù).解:μ=110,σ=20,P(X≥90)=P(X-110≥-20)=P(X-μ≥-σ),∵P(X-μσ)≈2P(X-μ130)=P(X-110>20)=P(X-μ>σ),∴P(X-μσ)≈0.683+2P(X-μ>σ)=1,∴P(X-μ>σ)=0.158 5,即P(X>130)=0.158 5.∴54×0.158 5≈9(人),即130分以上的人數(shù)約為9人.
按照“誰起草、誰審查”的原則,結(jié)合工作實際,我局制定下發(fā)了《XX市XX區(qū)司法局關(guān)于關(guān)于在市場體系建設(shè)中建立公平競爭審查制度的通知》,并要求局屬各部門負責(zé)本部門出臺政策措施的公平競爭審查和合法性審查工作,在起草文件過程中嚴格對照《XX市XX區(qū)人民政府辦公室關(guān)于在市場體系建設(shè)中建立公平競爭審查制度的通知》(晉政辦通〔2017〕138號)要求中的內(nèi)容,就審查對象、標準和要求進行嚴格審查。確保我局制定的有關(guān)政策措施符合公平競爭和相關(guān)法律法規(guī)要求,防止出現(xiàn)排除、限制競爭的情況。二、有序開展自查清理工作根據(jù)自查清理工作要求,我局認真對發(fā)文進行重點審查,對已出臺的政策文件,嚴格進行自我審查。經(jīng)清理,我局一季度未出臺過涉及市場主體經(jīng)濟活動的規(guī)章、規(guī)范性文件、其他政策措施等。三、工作亮點
