第八周國(guó)旗下講話稿：行為規(guī)范和文明習(xí)慣
我們走在整潔美麗的校園，坐在寬敞明亮的教室，也許你并不在意自己偶然說出的一句話，也許你不留心踩在腳下的花草，也許你已經(jīng)習(xí)慣自己旁若無人的喧叫。作為新時(shí)代的學(xué)生，我們的一舉一動(dòng)、一言一行都是我們內(nèi)心情感的外露，都是我們品德情操的體現(xiàn)。古人云“勿以惡小而為之，勿以善小而不為”，沒有規(guī)矩不成方圓，為了保證人們正常生活，每個(gè)國(guó)家都有法律法規(guī)，與此同理，在學(xué)校我們要成為合格的學(xué)生，最基本的就是遵守校紀(jì)校規(guī)。但是，同學(xué)們，在我們身邊經(jīng)常存在這樣的現(xiàn)象，就在許多同學(xué)用自己的實(shí)際行動(dòng)美化我們校園的同時(shí)，一些極不和-諧的音符仍在跳躍著，一些令人極不滿意的現(xiàn)象時(shí)有發(fā)生。我們不難看到，在花壇里，有我們同學(xué)扔的飲料罐、糖紙；在草地上，有我們同學(xué)丟的廢紙、方便袋；在課間操的時(shí)候，有的同學(xué)推推攘攘，高聲喧嘩；在莊嚴(yán)肅穆的升旗儀式上，有的同學(xué)左顧右盼，竊竊私語。課間難得十分鐘，你可以看看遠(yuǎn)處，讓眼睛得到休息，可有的同學(xué)偏要和同學(xué)推推搡搡，摔疼了，摔傷了，才懊喪不已
第五周國(guó)旗下講話稿：文明始于細(xì)節(jié)
敬愛的老師，親愛的同學(xué)：大家下午好！我是來自八年級(jí)6班的xx，今天我演講的題目是“文明始于細(xì)節(jié)”。亨·哈·埃利斯曾經(jīng)說過：“萬物之中，文明是最脆弱的，任何高度的文明都經(jīng)不起它所面臨多重危險(xiǎn)的威脅?！蔽拿魇侨祟愃鶆?chuàng)造的財(cái)富的總和。在這個(gè)物質(zhì)文明高度繁榮的年代里，我們的精神文明卻愈發(fā)薄弱。常常有人嘆：昔非今比，人心不古。新加坡是一個(gè)通用英語的國(guó)家，這個(gè)國(guó)家的公共場(chǎng)所的各種標(biāo)語大多是用英語書寫。但其中的一些涉及文明禮貌的標(biāo)語，如“不準(zhǔn)隨地吐痰”、“禁止吸煙”、“不準(zhǔn)進(jìn)入草坪”等卻是用中文書寫。為什么呢？人家回答：因?yàn)橛羞@些不文明行為的多數(shù)是中國(guó)大陸的游客。所以,這些標(biāo)識(shí)都使用中文書寫。作為中國(guó)人,難道不為自己的行為羞恥么?為此，到新加坡考察的一位中學(xué)校長(zhǎng)語重心長(zhǎng)地說：不文明行為也是國(guó)恥，這是時(shí)代進(jìn)步的產(chǎn)物,還是民族劣根性的暴露呢?

The theme of this part is to write an article about healthy diet. Through reading and writing activities, students can accumulate knowledge about healthy diet, deepen their understanding of the theme of healthy diet, and reflect on their own eating habits. This text describes the basic principles of healthy diet. The author uses data analysis, definition, comparison, examples and other methods. It also provides a demonstration of the use of conjunctions, which provides important information reference for students to complete the next collaborative task, writing skills, vivid language materials and expressions.1.

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(jī)抽取4件．設(shè)抽取的4件產(chǎn)品中次品數(shù)為X，求隨機(jī)變量X的分布列.（1）：采用有放回抽樣，隨機(jī)變量X服從二項(xiàng)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(dú)立,此時(shí)X服從二項(xiàng)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(xiàng)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(jī)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(jī)變量X服從超幾何分布．

(2)方法一:第一次取到一件不合格品,還剩下99件產(chǎn)品,其中有4件不合格品,95件合格品,于是第二次又取到不合格品的概率為4/99,由于這是一個(gè)條件概率,所以P(B|A)=4/99.方法二:根據(jù)條件概率的定義,先求出事件A,B同時(shí)發(fā)生的概率P(AB)=(C_5^2)/(C_100^2 )=1/495,所以P(B|A)=(P"(" AB")" )/(P"(" A")" )=(1/495)/(5/100)=4/99.6.在某次考試中,要從20道題中隨機(jī)地抽出6道題,若考生至少答對(duì)其中的4道題即可通過;若至少答對(duì)其中5道題就獲得優(yōu)秀.已知某考生能答對(duì)其中10道題,并且知道他在這次考試中已經(jīng)通過,求他獲得優(yōu)秀成績(jī)的概率.解:設(shè)事件A為“該考生6道題全答對(duì)”,事件B為“該考生答對(duì)了其中5道題而另一道答錯(cuò)”,事件C為“該考生答對(duì)了其中4道題而另2道題答錯(cuò)”,事件D為“該考生在這次考試中通過”,事件E為“該考生在這次考試中獲得優(yōu)秀”,則A,B,C兩兩互斥,且D=A∪B∪C,E=A∪B,由古典概型的概率公式及加法公式可知P(D)=P(A∪B∪C)=P(A)+P(B)+P(C)=(C_10^6)/(C_20^6 )+(C_10^5 C_10^1)/(C_20^6 )+(C_10^4 C_10^2)/(C_20^6 )=(12" " 180)/(C_20^6 ),P(E|D)=P(A∪B|D)=P(A|D)+P(B|D)=(P"(" A")" )/(P"(" D")" )+(P"(" B")" )/(P"(" D")" )=(210/(C_20^6 ))/((12" " 180)/(C_20^6 ))+((2" " 520)/(C_20^6 ))/((12" " 180)/(C_20^6 ))=13/58,即所求概率為13/58.
