The theme of this section is “Talk about festival activities and festival experiences”.Festival and holiday is a relaxing and interesting topic for students. This part talks about the topic from the daily life of students’. In the part A ---Listening and Speaking, there are three conversations among different speakers from three countries(Japan, Rio and China), where the speakers are participating in or going to participate in the festivals and celebrations. So listening for the relationship among them is a fundamental task. Actually, with the globalization and more international communication, it is normal for Chinese or foreigners to witness different festivals and celebrations in or out of China. In the Conversation 1, a foreign reporter is interviewing a Japanese young girl who just had participated in the ceremony of the Coming-of-Age Day on the street and asking her feeling about the ceremony and the afterwards activities. Conversation 2, Chinese girl Li Mei is witnessing the Rio Carnival for the first time, and her friend Carla gives her some advice on the costumes which enables her to match with the carnival to have a good time. Conversation 3, a Chinese guide is showing a group of foreign visitors around the Lantern Festival and introducing the customs of the festival to them. The three conversations have a strong vitality and insert the festival and cultural elements from different countries. So perceiving the festivals and cultures from different countries is the second task. At the same time, the scripts also insert the targeted grammar --- v-ing as attributive and predicative, which students can perceive and experience in a real context and make a road for the further study. That is the third task. In the Part B--- Listening and Talking, the theme is “Talk about festival experience”, which is the common topic in our daily conversations. During the conversation, Song Lin, a Chinese student, asked Canadian friend Max about how to spend Christmas. In the conversation, Song Lin talked about experience and the feelings during the Chinese Spring Festival, during which there are not only some enjoyable things but some unpleasant things. After the listening, perhaps students find there are some similarities between Christmas and the Chinese Spring Festival as there are some differences in the origins and celebrations. For example, people always visit friends and relatives, decorate their houses, have a big dinner together, chat and give presents to each other.

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.

（一）教材的地位與作用本節(jié)教材主要從兩個(gè)方面闡述課程標(biāo)準(zhǔn)：第一是地球的內(nèi)部圈層，要求能夠說(shuō)出地球內(nèi)部圈層主要包括地殼、地幔和地核；第二是地球的外部圈層，包括大氣圈、水圈和生物圈；還有介于內(nèi)部和外部圈層之間的一個(gè)圈層，包括地殼和上地幔頂部，即軟流層之上的固體巖石部分。本條標(biāo)準(zhǔn)有顯性和隱性兩方面的要求，顯性要求是從宏觀上了解地球結(jié)構(gòu)的特點(diǎn)，隱性要求是了解自然環(huán)境的組成。在宏觀了解地球圈層結(jié)構(gòu)的基礎(chǔ)上認(rèn)識(shí)自然環(huán)境的組成，即在空間范圍上把自然環(huán)境放在地球圈層結(jié)構(gòu)中認(rèn)識(shí)。但是對(duì)于各圈層不要求展開深入了解，而應(yīng)抓其主要特點(diǎn)及與人類活動(dòng)關(guān)系密切的內(nèi)容。（二）教學(xué)目標(biāo)(1)知識(shí)與技能目標(biāo)：1.了解地球圈層結(jié)構(gòu)及特點(diǎn)，知道地球內(nèi)部圈層的組成及其劃分依據(jù)；2.嘗試根據(jù)地震波劃分地球內(nèi)部圈層，并能概括出各圈層的主要特點(diǎn)；3.運(yùn)用圖表了解地球表層的含義。
人教版新課標(biāo)高中物理必修1力學(xué)單位制說(shuō)課稿
今天我說(shuō)課的內(nèi)容是人教版高中物理必修1第四章第四節(jié)《力學(xué)單位制》，我的說(shuō)課內(nèi)容將按下列程序展開。首先是本節(jié)教材的分析。一、說(shuō)教材1、本節(jié)課在教材中的地位單位是學(xué)生在高考中最容易犯錯(cuò)的地方之一，本節(jié)課內(nèi)容貫穿整個(gè)物理學(xué)科的每部分。學(xué)好這部分內(nèi)容對(duì)所有的自然學(xué)科都有幫助。2、教材簡(jiǎn)析教材可分為：?jiǎn)挝恢频雀拍畹膩?lái)源和單位制的推廣。二、說(shuō)教學(xué)目標(biāo)：教學(xué)目標(biāo)的設(shè)定是教師進(jìn)行課堂授課的一個(gè)重要依據(jù)，是教師完成教學(xué)任務(wù)的鑒定標(biāo)準(zhǔn)。根據(jù)新課標(biāo)要求和學(xué)生特點(diǎn)我對(duì)本節(jié)制定以下教學(xué)目標(biāo)（1）了解什么是單位制，知道國(guó)際單位制中力學(xué)的三個(gè)基本單位。（2）認(rèn)識(shí)單位制在物理學(xué)中和國(guó)際交往中的重要作用。（3）學(xué)會(huì)用單位運(yùn)算來(lái)檢查物理公式推導(dǎo)的正確性，從而培養(yǎng)學(xué)生解決實(shí)際問題的能力。
人教版新課標(biāo)高中物理必修1自由落體運(yùn)動(dòng)說(shuō)課稿2篇
學(xué)生回答的方法多樣，讓各小組根據(jù)自己討論出來(lái)的方法對(duì)自己實(shí)驗(yàn)出來(lái)的紙帶進(jìn)行數(shù)據(jù)處理，并求出加速度，并且將多條紙帶都進(jìn)行處理，同時(shí)提醒學(xué)生對(duì)紙帶的選擇。接著，我會(huì)用多媒體展示重物下落實(shí)驗(yàn)打出來(lái)的紙帶，用表格列出一段紙帶上各點(diǎn)的瞬時(shí)速度，準(zhǔn)確畫出v-t圖像，求出加速度，將結(jié)果給予學(xué)生的結(jié)果作對(duì)比，確定出正確結(jié)論。最后讓學(xué)生分析總結(jié)：自由落體運(yùn)動(dòng)是初速度為零的勻加速直線運(yùn)動(dòng)，而且，多條紙帶算出來(lái)的加速度的數(shù)值都接近相等，即加速度在實(shí)驗(yàn)誤差允許范圍內(nèi)是相等的。引出重力加速度，介紹概念、方向及大小。（強(qiáng)調(diào)“同一地點(diǎn)”，讓學(xué)生閱讀教材中一些地點(diǎn)的重力加速度，可以了解重力加速度的大小與緯度有關(guān)，緯度越大加速度越大）。學(xué)習(xí)了重力加速度后讓學(xué)生根據(jù)之前學(xué)習(xí)的勻變速直線運(yùn)動(dòng)公式推導(dǎo)出自由落體的運(yùn)動(dòng)規(guī)律。設(shè)計(jì)意圖：讓學(xué)生在學(xué)習(xí)過程中的主體地位和自主觀能動(dòng)性得到充分發(fā)揮，取長(zhǎng)補(bǔ)短，培養(yǎng)了學(xué)生的實(shí)驗(yàn)操作能力，又使學(xué)生對(duì)自由落體運(yùn)動(dòng)的性質(zhì)有深刻的印象，從而解決了本節(jié)課第二個(gè)難點(diǎn)。
人教版高中生物必修1生命活動(dòng)的主要承擔(dān)者—蛋白質(zhì)說(shuō)課稿
第五，蛋白質(zhì)的功能。蛋白質(zhì)功能具有多樣性，由學(xué)生對(duì)照教材，進(jìn)行總結(jié)。為什么蛋白質(zhì)有那么多功能呢？根據(jù)我們學(xué)習(xí)生物學(xué)的經(jīng)驗(yàn)可知道：生物的結(jié)構(gòu)決定功能。再要求剛才的那四個(gè)同學(xué)上臺(tái)組合多肽鏈。以不同位置組合，就會(huì)形成很多種多肽鏈，進(jìn)而形成很多種蛋白質(zhì)。每一種蛋白質(zhì)都有其特定的功能，所以蛋白質(zhì)具有多樣性，其功能也具有多樣性。第六，總結(jié)。蛋白質(zhì)是細(xì)胞和生物體中重要的有機(jī)化合物，是一切生命活動(dòng)的主要承擔(dān)者。蛋白質(zhì)的多樣性是形形色色生物和絢麗多彩生命活動(dòng)的物質(zhì)基礎(chǔ)。（可以由學(xué)生總結(jié)）第七，教學(xué)評(píng)價(jià)。由于只有一節(jié)課時(shí)間，課堂上對(duì)重點(diǎn)、難點(diǎn)知識(shí)的解析還不能做到舉一反三的深度，因此盡管學(xué)生課堂反應(yīng)熱烈，對(duì)知識(shí)點(diǎn)的接受程度也達(dá)到了預(yù)期的要求，但在做課后練習(xí)時(shí)，也會(huì)出現(xiàn)一些問題。所以傳統(tǒng)的講練結(jié)合還是要結(jié)合起來(lái)運(yùn)用才能取得更好的效果。為此本節(jié)內(nèi)容需要2課時(shí)來(lái)完成。

人教版高中語(yǔ)文必修1《奧斯維辛沒有什么新聞》說(shuō)課稿2篇
第11段很短，只點(diǎn)出了這是“在婦女身上搞不育試驗(yàn)的地方”，但在最末又加了一句“否則他會(huì)羞紅了臉的”，這是為什么？那肯定是一個(gè)極為骯臟，極為殘酷的地方。據(jù)資料記載：當(dāng)時(shí)的希特勒制定一項(xiàng)令所有被征服或占領(lǐng)國(guó)家的民族充當(dāng)奴隸并且逐漸消亡的隱密性種族滅絕計(jì)劃——高效率、大規(guī)模的強(qiáng)制絕育。為此，數(shù)以百計(jì)的納粹醫(yī)生、教授、專家甚至護(hù)士，在行政管理專家的通力合作下，相繼提出了幾十種絕育方法，十余種實(shí)施方案，并且在奧斯維辛、拉芬斯布呂克、布亨瓦爾特、達(dá)豪等十多個(gè)大型集中營(yíng)內(nèi)對(duì)數(shù)以萬(wàn)計(jì)的猶太、吉普賽囚犯、因從事抵抗運(yùn)動(dòng)而被捕的政治犯和男女戰(zhàn)俘進(jìn)行了殘酷的手術(shù)試驗(yàn)，造成他們大量死亡或者終身殘疾、終身不育。這樣殘酷的毫無(wú)人性的手段，任誰(shuí)也不愿看到。
