This section guides students to pay attention to the typical context of vocabulary use, helps students accumulate vocabulary around the key vocabulary of this unit, and uses the learned words and word chunks in different contexts to deeply understand their meaning and usage, so as to achieve the purpose of review and consolidation.The teaching design activities aim to guide students to pay attention to the typical context in which the target vocabulary is used, as well as the common vocabulary used in collocation, so that students can complete the sentence with correct words. In terms of vocabulary learning strategies, this unit focuses on cultivating students' ability to pay attention to collocation of words and to use word blocks to express meaning.For vocabulary learning, it is not enough just to know the meaning of a single word, but the most important thing is to master the common collocations of words, namely word blocks.Teachers should timely guide students to summarize common vocabulary collocation, such as verb and noun collocation, verb and preposition collocation, preposition and noun collocation, and so on.1. Guide students to understand and consolidate the meaning and usage of the vocabulary in the context, 2. Guide the students to use the unit topic vocabulary in a richer context3. Let the students sort out and accumulate the accumulated vocabulary, establishes the semantic connection between the vocabulary,4. Enable students to understand and master the vocabulary more effectivelyGuiding the Ss to use unit topic words and the sentence patterns in a richer context.

(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(guò);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(guò),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(guò)”,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.

一、談話(huà)交流，導(dǎo)入課題。1.同學(xué)們，《鑿壁偷光》的故事大家聽(tīng)說(shuō)過(guò)嗎？【課件出示2：圖文】匡衡勤奮好學(xué)，可是家境貧寒，晚上想讀書(shū)而無(wú)燭照明。鄰居家倒是每到夜晚，總燭光明亮，可惜這光照不到他匡衡的屋里。怎么辦呢?匡衡便把自己家靠鄰舍的那堵墻壁鑿開(kāi)一個(gè)洞以引鄰居家的燭光來(lái)讀書(shū)。古時(shí)候，還有一位熱愛(ài)讀書(shū)的人，他是晉代車(chē)胤，因?yàn)榧邑?，沒(méi)錢(qián)買(mǎi)燈油，而又想晚上讀書(shū)，便在夏天晚上抓一把螢火蟲(chóng)來(lái)當(dāng)燈讀書(shū)。2.這個(gè)故事就是《囊螢夜讀》，今天，我們來(lái)學(xué)習(xí)一下這個(gè)小故事。（板書(shū)：囊螢夜讀）學(xué)生齊讀課題。3.這是一篇文言文。千古傳誦，流傳至今。4.補(bǔ)充文言文知識(shí)：文言文人們通常說(shuō)古文。我國(guó)是一個(gè)文明古國(guó)，我國(guó)古代有著燦爛的文化，有著浩如煙海的文學(xué)藝術(shù)瑰寶，他們都是以文言文的形式記載下來(lái)的。我們要去傳承民族的瑰寶，就要學(xué)好文言文。【課件出示3】

1.出示《斗牛圖》，學(xué)生觀察，交流發(fā)現(xiàn)。以形象直觀的感受入題，讓學(xué)生看圖,和故事中的人物有了聯(lián)系，拉近了與文本的距離。有了自己看圖的感受，這樣在學(xué)習(xí)文中牧童指出的問(wèn)題時(shí)便有了更深的印象，更易與人物產(chǎn)生共鳴。2.初讀感知。按前面文言文學(xué)習(xí)的方法，學(xué)生練習(xí)朗讀、理解文意。我隨機(jī)點(diǎn)撥。在疏通文意的基礎(chǔ)上也讓學(xué)生用自己的話(huà)說(shuō)說(shuō)這個(gè)故事，幫助理解把握文章內(nèi)容。在學(xué)生說(shuō)的同時(shí)也引導(dǎo)他們展開(kāi)想象，豐富描述的內(nèi)容，體會(huì)藝術(shù)之美。3.研讀感悟。圍繞故事的主要人物展開(kāi)，讓學(xué)生感知人物形象。通過(guò)對(duì)人物語(yǔ)言、態(tài)度的分析，創(chuàng)設(shè)情境，引導(dǎo)學(xué)生展開(kāi)想象:牧童的動(dòng)作、表情、畫(huà)上的內(nèi)容;杜處士聽(tīng)到牧童的話(huà)可能會(huì)想些什么?

一、文本解讀《伯牙鼓琴》是小學(xué)語(yǔ)文六年級(jí)上冊(cè)的一篇文言文。故事蕩氣回腸、耐人尋味。伯牙喜歡彈琴，子期有很高的音樂(lè)鑒賞能力。伯牙把感情溶進(jìn)樂(lè)曲中去，用琴聲表達(dá)了他像高山一樣巍然屹立于天地之間的情操，以及像大海一樣奔騰于宇宙之間的智慧，琴技達(dá)到了爐火純青的地步。而鐘子期的情操、智慧正好與他產(chǎn)生了共鳴。不管伯牙如何彈奏，子期都能準(zhǔn)確地道出伯牙的心意。伯牙因得知音而大喜。子期死后，伯牙悲痛欲絕，覺(jué)得世上再?zèng)]有人能如此真切地理解他，“破琴絕弦，終身不復(fù)鼓琴”。古人說(shuō)：“士為知己者死。”伯牙絕弦，所喻示的正是一種真知己的境界，這也正是它千百年來(lái)廣為流傳的魅力所在。選編這篇課文的意圖，一是讓學(xué)生借助注釋初步了解文言文的大意；二是積累中華優(yōu)秀經(jīng)典詩(shī)文，感受朋友間相互理解、相互欣賞的純真友情；三是體會(huì)音樂(lè)藝術(shù)的無(wú)窮魅力。

一、說(shuō)教材《文言文二則》是統(tǒng)編語(yǔ)文小學(xué)六年級(jí)下冊(cè)第五單元中的一篇精讀課文，有兩篇文言文組成?！秾W(xué)弈》這篇文言文選自《孟子·告子上》，通過(guò)弈秋教兩個(gè)人學(xué)下圍棋的事，說(shuō)明了做事必須專(zhuān)心致志，決不可三心二意的道理。文章先說(shuō)弈秋是全國(guó)最擅長(zhǎng)下圍棋的人，然后講弈秋同時(shí)教兩個(gè)學(xué)習(xí)態(tài)度不同的人下圍棋，學(xué)習(xí)效果截然不同，最后指出這兩個(gè)人學(xué)習(xí)結(jié)果不同，并不是在智力上有多大差異。《兩小兒辯日中》它是一篇寓言故事，選自《列子·湯問(wèn)》。文章敘述古時(shí)候兩個(gè)孩子憑著自己的直覺(jué)，一個(gè)認(rèn)為太陽(yáng)早晨離人近，一個(gè)認(rèn)為太陽(yáng)在中午離人近，為此各持一端，爭(zhēng)持不下，就連孔子這樣博學(xué)的人也不能做出判斷。這個(gè)故事說(shuō)明為了認(rèn)識(shí)自然，兩小兒勇于探索，大膽質(zhì)疑的品質(zhì)，也說(shuō)明宇宙無(wú)限，知識(shí)無(wú)窮，再博學(xué)的人也有所不知，學(xué)習(xí)是無(wú)止境的。同時(shí)也贊揚(yáng)了孔子實(shí)事求是、敢于承認(rèn)自己學(xué)識(shí)不足的精神和古代人民敢于探求客觀真理。
