So I will practice their speaking and reading abilities through different exercises.According to the New Standard Curriculum and the present situation, I set the teaching aims as follows: firstly, knowledge aims. Students can grasp some new words, such as worthwhile, move off. Moreover, students can understand the content of the passage and get familiar with the topic of studying chimps in wildlife. Secondly, ability aims. Students can use reading strategies such as skimming and scanning in reading process. Thirdly, emotional aims.

人教版高中英語(yǔ)必修4A taste of English Humor說(shuō)課稿3篇
Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill

世界環(huán)境日國(guó)旗下講話稿范本
各位老師、各位同學(xué)：大家好!21世紀(jì)可謂挑戰(zhàn)與機(jī)遇同在，希望與困難并存。生活在給我們帶來(lái)許多美好憧憬的同時(shí)，也給我們帶來(lái)了許多難題。其中首要的就是環(huán)境問(wèn)題。環(huán)境問(wèn)題是由于人類不合理地開發(fā)與利用自然所造成的。隨著世界環(huán)境問(wèn)題的日益嚴(yán)重，我們賴以生存的地球引起了世人普遍的的關(guān)注與討論。1972年6月5日，人類環(huán)境會(huì)議在瑞典首都斯德哥爾摩召開，會(huì)議通過(guò)了《人類環(huán)境宣言》;同年10月，第27屆聯(lián)合國(guó)大會(huì)通過(guò)決議，將以后每年的6月5日定為世界環(huán)境日?，F(xiàn)在我們又迎來(lái)了世界環(huán)境日。今年的主題為“你的星球需要你，聯(lián)合起來(lái)應(yīng)對(duì)氣候變化”，我國(guó)確定的主題為“減少污染——行動(dòng)起來(lái)”。是的，我們的地球母親已經(jīng)承受了太多的苦難。早在1996年聯(lián)合國(guó)環(huán)境署就曾發(fā)出警告：南極臭氧空洞正逐步增大，地面紫外線輻射增強(qiáng)，皮膚癌發(fā)病率上升;億人口生活在混濁的空氣里;12億人口缺水;每年地表土壤流失200億噸;森林以每年45萬(wàn)公頃的速度消失?，F(xiàn)在全球每年有600萬(wàn)公頃的土地淪為沙漠，平均每小時(shí)就有一個(gè)物種在滅絕。溫室效應(yīng)使海平面不斷升高，世界上眾多城市、島嶼和大量土地，用不了多久將被海水吞沒。
第10周國(guó)旗下講話：世界勤儉日
尊敬的老師們，親愛的同學(xué)們：早上好！誰(shuí)知道10月31日是什么日子？是《世界勤儉日》。大概沒有多少人記得這個(gè)節(jié)日。世界勤儉日的確立旨在號(hào)召人們勤儉節(jié)約以共同應(yīng)對(duì)日益嚴(yán)重的資源危機(jī)，進(jìn)而促進(jìn)社會(huì)的健康可持續(xù)發(fā)展。勤儉節(jié)約，是中華民族的傳統(tǒng)美德，我國(guó)自古就有：“一粥一飯，當(dāng)思來(lái)處不易，半絲半縷，恒念物力維艱”的至理名言。周恩來(lái)總理勤儉節(jié)約的故事，婦孺皆知，成為美談。他一貫倡導(dǎo)勤儉建國(guó)、艱苦奮斗，要求“一切招待必須是國(guó)貨，必須節(jié)約樸素，切忌鋪張華麗、有失革命精神和艱苦奮斗的作風(fēng)”。1961年12月4日召集專門委員會(huì)對(duì)當(dāng)時(shí)第二機(jī)械工業(yè)部的一個(gè)規(guī)劃進(jìn)行審議，會(huì)議從上午開到中午還沒結(jié)束，周總理留大家吃午飯。餐桌上是一大盆肉丸熬白菜、豆腐，四周擺幾小碟咸菜和燒餅。周總理同大家同桌就餐，吃同樣的飯菜。這個(gè)故事至今聽來(lái)讓人覺得很有教育意義。
關(guān)于世界殘疾人日國(guó)旗下講話
篇一： 關(guān)于世界殘疾人日國(guó)旗下講話各位老師、同學(xué)們，大家好!我今天演講的題目是《讓關(guān)愛的陽(yáng)光照亮殘疾人的心靈》，人生在世，首先要知道有愛，學(xué)會(huì)感恩。父母親情、同學(xué)友情、老師恩情，甚至素不相識(shí)的人的一聲問(wèn)候、一個(gè)微笑，都是愛的表現(xiàn)?？嚯y的人因?yàn)閻鄱吹较Ｍ腋５娜艘驗(yàn)閻鄱谜湎?，富有的人因?yàn)閻鄱瞰I(xiàn)，貧困的人因?yàn)閻鄱詮?qiáng)，在這個(gè)世界上，我們感受著愛，也付出著愛。在這個(gè)社會(huì)上，有一個(gè)群體需要我們特別的關(guān)愛。當(dāng)我們每天迎著朝陽(yáng)，走向光明的人生時(shí)，他們卻是需要依靠冰冷的輪椅度過(guò)人生的每一個(gè)臺(tái)階;當(dāng)我們和家人齊聚在電視機(jī)旁，共同欣賞每一個(gè)精彩節(jié)目時(shí)，他們卻連聆聽鳥語(yǔ)、觀看藍(lán)天也是一種奢望。同在一個(gè)大家庭中，這些殘疾人的生活，較之我們，卻是如此的艱苦!面對(duì)命運(yùn)的不公平，他們，更需要家人的親情和世人的溫情。然而，同學(xué)們，你們對(duì)殘疾人的關(guān)懷有多少?有誰(shuí)知道全國(guó)助殘日?《中華人民共和國(guó)殘疾人保障法》規(guī)定：每年5月的第三個(gè)星期日，為全國(guó)助殘日。
高中物理人教版必修一《彈力》說(shuō)課稿
二、學(xué)情分析：學(xué)生目前對(duì)形變和彈力有一定的感性認(rèn)識(shí)但是不夠深入；知道支持力、壓力都是彈力，但是不能夠概括產(chǎn)生的原因。理性思維還沒有達(dá)到一定的層次，要想理解彈力這一抽象概念還有一定困難。因此我采取引導(dǎo)、啟發(fā)的教學(xué)方式。
