1. First, ... then, ... next, ... finally, ...首先,……然后,……接著,……最后,……這是英語(yǔ)中表達(dá)做某事的步驟的一種說(shuō)法。如果步驟較多,還可以說(shuō):first-next-after that-later on-finally/at last通常你會(huì)聽(tīng)到說(shuō)英語(yǔ)國(guó)家的人在說(shuō) first, next, then, finally 和后面的內(nèi)容時(shí),他們會(huì)做一些停頓。這樣就能提前告訴聽(tīng)者接下來(lái)講的是一系列的步驟。這一點(diǎn)在朗讀和聽(tīng)力中應(yīng)特別注意。2. how many, how much均為疑問(wèn)詞,同是“多少”,但用法不同。請(qǐng)看:how many修飾可數(shù)名詞復(fù)數(shù),how much修飾不可數(shù)名詞。但在用法上,同學(xué)們常犯如下錯(cuò)誤:1) [誤] How many are there bananas on the table?[正] How many bananas are there on the table?[析] how many, how much 中的many,much是形容詞,常修飾名詞作定語(yǔ),故后面跟名詞。2) [誤]How much tea are there on the table?[正]How much tea is there on the table?[析] how much修飾不可數(shù)名詞時(shí),謂語(yǔ)動(dòng)詞用單數(shù)。how many與how much的區(qū)別可簡(jiǎn)記為:前how many:?jiǎn)枴岸嗌佟?,?fù)數(shù)名詞后面跑;how much問(wèn)“多少”,不可數(shù)名詞單數(shù)好。前者答語(yǔ)用基數(shù)詞,后者答語(yǔ)用數(shù)量關(guān)系。
“Go for it!” is based on “Task-Based Language Teaching”. It adheres to “The authenticity principle”, “The form-function principle”, “The task dependency principle” and “The principle of learning by doing”. These principles all accord with the demands of curriculum focus.In and of Grade Seven (II), “Go for it!”, students have learned “The Simple Past Tense”. And it appears again in of Grade Eight (I). teaches students more about how to talk about events in the past. In addition, it gives affirmative and negative statements in the past tense, such as the sentence patterns “Did you see …?” “Were there …?” “Did you go …?” As the first part of Unit 8, Section A opens with a picture presenting the last school trip in the aquarium and continues with several step-by-step practice activities, which are all good for students to master “The Simple Past Tense”. Doing well in Section A will help students integrate the new target language with that in Section B. Thus, they can describe the events in the past freely and foster their own ability of reflecting and practicing. II.

一、溫故導(dǎo)入好的導(dǎo)入未成曲調(diào)先有情,可以取得事半功信的教學(xué)效果。對(duì)于本節(jié)課我以溫故知新的方式導(dǎo)入,以蘇軾的《赤壁賦》和《念奴嬌》引導(dǎo)學(xué)生感受蘇軾的豪放和闊達(dá),從學(xué)生熟悉領(lǐng)域出發(fā),引導(dǎo)學(xué)生探究他內(nèi)心深處的“柔情似水”,感受他的“十年生死”之夢(mèng)。二、誦讀感知(亮點(diǎn)一)《語(yǔ)文課程標(biāo)準(zhǔn)》中建議“教師要充分關(guān)注學(xué)生閱讀需求的多樣性,閱讀心理的獨(dú)特性”。所以在本環(huán)節(jié)我將綜合運(yùn)用聽(tīng)、讀、問(wèn)、答四種方式教學(xué)。首先通過(guò)多媒體聽(tīng)讀,激發(fā)學(xué)生學(xué)習(xí)興趣,直觀感受蘇軾的痛徹心扉和傷心欲絕。其次指定學(xué)生誦讀,并在誦讀之后,由學(xué)生點(diǎn)評(píng),加深學(xué)生對(duì)于斷句、輕重、快慢的理解,進(jìn)一步感受本詞的凄苦哀怨。最后配樂(lè)讀,利用凄清的音樂(lè)引導(dǎo)學(xué)生通過(guò)自己的誦讀來(lái)表現(xiàn)詩(shī)中所蘊(yùn)含的真摯之感。設(shè)計(jì)意圖:通過(guò)多種閱讀方法,反復(fù)閱讀本詞,引導(dǎo)學(xué)生由淺入深的理解本詞的思想內(nèi)容和藝術(shù)風(fēng)格,初步感受作者對(duì)妻子的摯愛(ài)之情和他的痛徹心扉,加深學(xué)生對(duì)文章的理解。
答案:銅車(chē)馬的輝煌,來(lái)自原料的精挑細(xì)選、工藝的精巧極致和工匠的精心雕琢??梢哉f(shuō),是精益求精的工匠精神鍛造出了“青銅之冠”的銅車(chē)馬。2.“工匠精神”如此重要,那么,你認(rèn)為“工匠精神”有著怎樣的現(xiàn)實(shí)意義?觀點(diǎn)一:工匠精神在企業(yè)層面,可以認(rèn)為是企業(yè)精神。具體而言,表現(xiàn)在以下幾個(gè)方面。第一,創(chuàng)新是企業(yè)不斷發(fā)展的精神內(nèi)核。第二,敬業(yè)是企業(yè)領(lǐng)導(dǎo)者精神的動(dòng)力。第三,執(zhí)著是企業(yè)走得長(zhǎng)久的底氣。改革開(kāi)放40 多年來(lái),我國(guó)涌現(xiàn)出大批有工匠精神的企業(yè),但也有一些企業(yè)缺乏企業(yè)精神,只追求“短平快”的經(jīng)濟(jì)效益。這正是經(jīng)濟(jì)發(fā)展的隱憂所在。觀點(diǎn)二:工匠精神在員工層面,就是一-種認(rèn)真精神、敬業(yè)精神。其核心是: 不僅僅把工作當(dāng)作賺錢(qián)養(yǎng)家糊口的工具,而是樹(shù)立起對(duì)職業(yè)敬畏、對(duì)工作執(zhí)著、對(duì)產(chǎn)品負(fù)責(zé)的態(tài)度,極度注重細(xì)節(jié),不斷追求完美和極致,給客戶(hù)無(wú)可挑剔的體驗(yàn)。我國(guó)制造業(yè)存在大而不強(qiáng)、產(chǎn)品檔次整體不高、自主創(chuàng)新能力較弱等現(xiàn)象,多少與工匠精神稀缺、“差不多精神”有關(guān)。
一、說(shuō)教材:《操場(chǎng)上》有一幅表現(xiàn)操場(chǎng)上熱鬧的圖,6個(gè)表示體育運(yùn)動(dòng)的詞語(yǔ)和一首兒歌。圖上畫(huà)了小學(xué)生在操場(chǎng)上所玩的大部分體育活動(dòng),兒歌概括了操場(chǎng)上活動(dòng)的情形。通過(guò)這節(jié)課的學(xué)習(xí),可以激發(fā)學(xué)生參加體育鍛煉的興趣。我上的是第一課時(shí),在這節(jié)課上,我安排的學(xué)習(xí)任務(wù)是認(rèn)讀課文中的12個(gè)生字,學(xué)會(huì)寫(xiě)7兩個(gè)字。二、說(shuō)學(xué)生:一年級(jí)學(xué)生年齡較小,大多數(shù)學(xué)生活潑好動(dòng),大膽且獨(dú)立,對(duì)事物具有積極樂(lè)觀的態(tài)度,有意注意的時(shí)間較短,好動(dòng)、好玩是他們的天性。所以我就要想盡辦法,變著法兒的把他們引到課堂中來(lái),引導(dǎo)他們主動(dòng)一些的參與到我們的學(xué)習(xí)中。
一、結(jié)合生活情境與操作活動(dòng),初步認(rèn)識(shí)角,知道角各部分的名稱(chēng),初步學(xué)會(huì)用尺畫(huà)角?! ?.讓學(xué)生結(jié)合熟悉的生活情景圖,并從其中的實(shí)物圖中抽象出角,親歷操作活動(dòng)來(lái)認(rèn)識(shí)角,知道角的各部分的名稱(chēng),知道一個(gè)角由一個(gè)頂點(diǎn)和兩條邊組成,初步學(xué)會(huì)用尺畫(huà)角的方法?! ?.通過(guò)折疊、拼擺、制作等實(shí)際操作活動(dòng),幫助學(xué)生建立對(duì)角的感性認(rèn)識(shí),知道什么樣的圖形是角?! ?.讓學(xué)生知道畫(huà)一個(gè)角的方法:從一個(gè)點(diǎn)起,用尺子向不同的方向畫(huà)兩條直直的線,就畫(huà)成一個(gè)角?! ?.知道角的大小與角的兩邊的長(zhǎng)短沒(méi)有關(guān)系,與兩邊叉開(kāi)的大小有關(guān)。 5.通過(guò)觀察實(shí)物并從中抽象出角,經(jīng)歷數(shù)學(xué)知識(shí)抽象的過(guò)程,感受到數(shù)學(xué)知識(shí)的現(xiàn)實(shí)性,學(xué)會(huì)從數(shù)學(xué)的角度去觀察、分析現(xiàn)實(shí)問(wèn)題,從而激發(fā)學(xué)生探索數(shù)學(xué)的興趣。 二、在課程教學(xué)中,要注重挖掘角在生活中的“原型”。學(xué)生對(duì)此有一定的生活積累,但學(xué)生理解來(lái)自于他們作用于的物體的活動(dòng)。因此只有親自操作,獲得直接的經(jīng)驗(yàn),才便于在此基礎(chǔ)上進(jìn)行正確的抽象和概括,形成較系統(tǒng)的概念和數(shù)學(xué)模型。1.教師應(yīng)提供恰當(dāng)?shù)?、精心選擇的生活情景圖,讓學(xué)生找生活中的角,并將這種角與數(shù)學(xué)意義的上角加以區(qū)分、對(duì)比觀察,加深對(duì)數(shù)學(xué)意義上角的感知,從而引領(lǐng)學(xué)生從數(shù)學(xué)角度認(rèn)識(shí)角,建立角的正確表象。
三、說(shuō)教法和學(xué)法:1、說(shuō)教法:本節(jié)課采用幾何畫(huà)板與電子白板相結(jié)合的教學(xué)手段,使操作過(guò)程形象、直觀呈現(xiàn),以便學(xué)生更好的理解。在教學(xué)過(guò)程中,引導(dǎo)學(xué)生去探索,使學(xué)生感受到添加輔助線的數(shù)學(xué)思想,更好地掌握三角形內(nèi)角和定理的證明及簡(jiǎn)單的應(yīng)用,2、說(shuō)學(xué)法:根據(jù)本節(jié)課特點(diǎn)和學(xué)生的實(shí)際,在教學(xué)過(guò)程中給學(xué)生足夠的時(shí)間認(rèn)真、仔細(xì)地動(dòng)手書(shū)寫(xiě)證明過(guò)程,使學(xué)生的學(xué)習(xí)落到實(shí)處。同時(shí),培養(yǎng)學(xué)生科學(xué)的學(xué)習(xí)方法和自信心。四、說(shuō)教學(xué)過(guò)程設(shè)計(jì)教學(xué)過(guò)程的設(shè)計(jì)有:1、問(wèn)題引入新課:七年級(jí)已經(jīng)學(xué)習(xí)三角形內(nèi)角和定理內(nèi)容。這樣從已經(jīng)學(xué)過(guò)的知識(shí)引入,符合學(xué)生的認(rèn)知規(guī)律。在拼圖活動(dòng)中發(fā)展思維的靈活性、創(chuàng)造性,為下一環(huán)節(jié)“說(shuō)理”證明作好準(zhǔn)備,使學(xué)生體會(huì)到數(shù)學(xué)來(lái)源于實(shí)踐,同時(shí)對(duì)新知識(shí)的學(xué)習(xí)有了期待。
讓學(xué)生先獨(dú)立解決⑴題,再小組交流⑵題的答案,找到解題的方法.2、例2,例3是對(duì)平方根概念的鞏固與拓展,在例2中由于學(xué)生還不熟于平方根的表示方法,所以應(yīng)在平方根的概念和±號(hào)上加以明確,而例3則要把握平方根概念的本質(zhì),根據(jù)該數(shù)的正負(fù)或0來(lái)確定其平方根,這部分內(nèi)容可用板演或展臺(tái)展示結(jié)果的方式進(jìn)行,讓學(xué)生獨(dú)立完成,應(yīng)給予恰當(dāng)?shù)脑u(píng)價(jià).3、最后,我又設(shè)計(jì)了一道辨析題:在做一道求4的平方根的題目時(shí),小明說(shuō):“4的平方根是2”,小紅說(shuō):“4的平方根是-2”,小強(qiáng)說(shuō):“2是4的平方根”小芳說(shuō):“-2是4的平方根”,請(qǐng)問(wèn)他們的說(shuō)法正確嗎?通過(guò)這道題目,使學(xué)生在熟悉平方根概念的基礎(chǔ)上更加深理解,同時(shí)對(duì)以往五種運(yùn)算中從未出現(xiàn)過(guò)的一題兩解的現(xiàn)象作出了解釋?zhuān)箤W(xué)生明白了一種整體與局部的關(guān)系,再一次突出了重點(diǎn).
