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

一、導(dǎo)入新課人類(lèi)社會(huì)越來(lái)越現(xiàn)代化，新科學(xué)技術(shù)日新月異，令人目不暇接，稱(chēng)之到了“知識(shí)爆炸”的時(shí)代也毫不為過(guò)。由此而來(lái)的是生活的快節(jié)奏，學(xué)習(xí)和工作的競(jìng)爭(zhēng)也越來(lái)越激烈。這種競(jìng)爭(zhēng)一直波及到了兒童，加之中國(guó)幾千年來(lái)形成的望子成龍的傳統(tǒng)觀(guān)念，使作父母的把一切希望都寄托在孩子身上，實(shí)現(xiàn)自己未能實(shí)現(xiàn)的理想。祖孫三代4、2、1的局面，使12只眼睛都盯在了孩子身上，真是走路怕摔著，吃飯怕噎著，干活怕累著，要星星不敢摘月亮，要吃什么跑遍全城也要買(mǎi)來(lái)。這種過(guò)分保護(hù)、溺愛(ài)及過(guò)早地灌輸知識(shí)會(huì)得到什么結(jié)果呢？樂(lè)觀(guān)者說(shuō)孩子越來(lái)越聰明，越來(lái)越早熟，將來(lái)能更好適應(yīng)現(xiàn)代化的要求；悲觀(guān)者則認(rèn)為豆芽菜式的孩子將來(lái)經(jīng)不起風(fēng)浪，小皇帝太多了很難凝聚成統(tǒng)一力量，將來(lái)誰(shuí)去當(dāng)兵，誰(shuí)去干那些艱苦創(chuàng)業(yè)性工作……。對(duì)孩子本身來(lái)說(shuō)，是幸福還是……在此不想多發(fā)議論，還是讓我們來(lái)看看動(dòng)物世界的孩子們吧，也許會(huì)得到某種啟迪。

f.有絲分裂的意義（討論分析教學(xué)），首先引導(dǎo)學(xué)生結(jié)合所學(xué)知識(shí)討論有絲分裂的的作用，最后有教師歸納總結(jié)，并要求學(xué)生在理解的基礎(chǔ)上記憶。g.無(wú)絲分裂（圖形直觀(guān)教學(xué)、簡(jiǎn)介），本部分內(nèi)容不是教學(xué)的重點(diǎn)，內(nèi)容也相對(duì)簡(jiǎn)單，所以我的教學(xué)方法是直接給學(xué)生展示掛圖，再進(jìn)行簡(jiǎn)短介紹，讓學(xué)生了解即可。h.引出減數(shù)分裂的概念，為第五章學(xué)習(xí)打下基礎(chǔ)。小結(jié)：新課講完以后由教師對(duì)本節(jié)內(nèi)容進(jìn)行總結(jié)鞏固和反饋：進(jìn)行一些課堂練習(xí)達(dá)到鞏固和反饋的作用。最后布置作業(yè)，各種難度的作業(yè)題目均設(shè)置一些，其中簡(jiǎn)單題比重大，難題要求學(xué)生選作，這樣提高學(xué)生學(xué)習(xí)積極性。2教學(xué)媒體程序設(shè)計(jì): 細(xì)胞周期的概念（多媒體課件演示周期動(dòng)畫(huà)）植物細(xì)胞有絲分裂（多媒體課件演示分裂各期動(dòng)畫(huà)）動(dòng)植物細(xì)胞有絲分裂異同點(diǎn)（多媒體課件演示分裂各期動(dòng)畫(huà)）有絲分裂過(guò)程中DNA和染色體數(shù)量的變化規(guī)律（掛圖演示，包括表格和函數(shù)圖象）
人教版高中生物必修2伴性遺傳說(shuō)課稿
（1觀(guān)察圖解，色盲基因在性別間是如何傳遞的呢？（女--女、女--男、男--女）（2）為什么不能由男性傳給男性？（色盲基因是在X染色體上，因此色盲基因是隨X染色體的傳遞而傳遞。）（3）男性的色盲基因怎樣才能傳給男性呢？（通過(guò)女兒，傳給外孫即交叉遺傳）（4）從圖解看色盲在男女中的發(fā)病情況怎樣？（男性多于女性）（5）從社會(huì)調(diào)查也是這樣，你是否能從基因和染色體的角度加以解釋?zhuān)浚ㄌ崾荆号匀旧w的構(gòu)成，結(jié)合基因位置及顯隱性進(jìn)行分析）歸納特點(diǎn)：歸納出色盲基因遺傳的特點(diǎn)并擴(kuò)展到X染色體隱性遺傳的特點(diǎn)上。色盲基因遺傳（X隱性遺傳）的特點(diǎn)：（1）男患者多于女患者（2）交叉遺傳（3）女病兒子必病，男正女兒必正等。問(wèn)題探討：利用“遺傳圖解”結(jié)合“問(wèn)題鏈”繼續(xù)探討，拓展到抗維生素D即X 染色體顯性遺傳的特點(diǎn)。（6）色盲基因在X染色體上屬隱性基因，子代表現(xiàn)男多于女，對(duì)應(yīng)的正常色覺(jué)基因則屬于X顯性基因，子代表現(xiàn)應(yīng)如何？（女多于男）
人教版高中生物必修1細(xì)胞分化說(shuō)課稿
在講述細(xì)胞分化的意義時(shí)，也可以用實(shí)例來(lái)解決，工廠(chǎng)的生產(chǎn)車(chē)間里不同的工人干著不同的工作，一件產(chǎn)品的產(chǎn)出需要這些工人才能創(chuàng)造出來(lái)，一個(gè)生物體就像一個(gè)車(chē)間一樣，不同的細(xì)胞各司其職，相互合作。工人的分工是主管調(diào)解出來(lái)的，而不同細(xì)胞的出現(xiàn)就是細(xì)胞分化的結(jié)果，所以說(shuō)，細(xì)胞的分化是生物體發(fā)育的基礎(chǔ)。在講到細(xì)胞全能性的時(shí)候，要多給學(xué)生舉些關(guān)于細(xì)胞全能性的例子，如植物組織培養(yǎng)、克隆技術(shù)等等，讓學(xué)生從實(shí)際的例子中真正的悟出細(xì)胞全能性的含義。此外，還要重視教材中的疑問(wèn)，適當(dāng)對(duì)題目進(jìn)行引申,使它的作用更加突出，有利于學(xué)生對(duì)知識(shí)的串聯(lián)、積累、加工，從而達(dá)到舉一反三的效果。怎樣來(lái)解釋細(xì)胞的全能性呢？這主要以講授法來(lái)解釋了，細(xì)胞全能性的體現(xiàn)需要在組織或器官離體后才能體現(xiàn)出來(lái)，每個(gè)細(xì)胞都包含著生物體的全套遺傳基因，通過(guò)基因選擇性的表達(dá)，使離體的組織或器官通過(guò)分裂和分化逐漸發(fā)育成完整的植株。
