Step 3 (3b)First, tell the students when we talk about our future plans, we often use: I’m+verb+ing When we talk about what we must do, we use have to. Ask the students to fill in the blanks in 3b.

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)枴岸嗌佟保瑥?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. Teaching ObjectivesTeaching objective is the beginning and aim of teaching activities. According to the overall goal of the English elementary course--- improve students' synthetic ability of language application, which should be based on the development of students’ “Language knowledge”, “Language skills”, “Character building”, “Learning strategies” and “Cross-cultural awareness”.

【學(xué)習(xí)目標(biāo)】1.知識(shí)與技能:加深對(duì)燃燒條件的認(rèn)識(shí),進(jìn)一步了解滅火的原理。2.過(guò)程與方法:體驗(yàn)實(shí)驗(yàn)探究的過(guò)程,學(xué)習(xí)利用實(shí)驗(yàn)探究的方法研究化學(xué)。3.情感態(tài)度與價(jià)值觀:利用化學(xué)知識(shí)解釋實(shí)際生活中的具體問(wèn)題,使學(xué)生充分體會(huì)到化學(xué)來(lái)源于生活,服務(wù)于社會(huì)?!緦W(xué)習(xí)重點(diǎn)】通過(guò)物質(zhì)燃燒條件的探究,學(xué)習(xí)利用控制變量的思想設(shè)計(jì)探究實(shí)驗(yàn),說(shuō)明探究實(shí)驗(yàn)的一般過(guò)程和方法?!緦W(xué)習(xí)難點(diǎn)】利用控制變量的思想設(shè)計(jì)對(duì)照實(shí)驗(yàn)進(jìn)行物質(zhì)燃燒條件的探究。【課前準(zhǔn)備】《精英新課堂》:預(yù)習(xí)學(xué)生用書(shū)的“早預(yù)習(xí)先起步”。《名師測(cè)控》:預(yù)習(xí)贈(zèng)送的《提分寶典》。情景導(dǎo)入 生成問(wèn)題1.復(fù)習(xí):什么叫燃燒?燃燒條件有哪些?今天自己設(shè)計(jì)實(shí)驗(yàn)來(lái)進(jìn)行探究。2.明確實(shí)驗(yàn)?zāi)繕?biāo),導(dǎo)入新課。合作探究 生成能力學(xué)生閱讀課本P150的相關(guān)內(nèi)容并掌握以下內(nèi)容。實(shí)驗(yàn)用品:鑷子、燒杯、坩堝鉗、三腳架、薄銅片、酒精、棉花、乒乓球、濾紙、蠟燭。你還需要的實(shí)驗(yàn)用品:酒精燈、水。1.實(shí)驗(yàn):用棉花分別蘸酒精和水,放到酒精燈火焰上加熱片刻。上述實(shí)驗(yàn)中我們能觀察到什么現(xiàn)象?說(shuō)明燃燒需要什么條件?如果在酒精燈上加熱時(shí)間較長(zhǎng),會(huì)發(fā)生什么現(xiàn)象?答:蘸酒精的棉花燃燒,蘸水的棉花沒(méi)有燃燒,說(shuō)明燃燒需要有可燃物。如果加熱時(shí)間較長(zhǎng),水蒸發(fā)后,蘸水的棉花也會(huì)燃燒。2.如圖所示,進(jìn)行實(shí)驗(yàn):我們能觀察到什么現(xiàn)象?說(shuō)明燃燒需要什么條件?答:在酒精燈火焰上加熱乒乓球碎片和濾紙碎片,都能燃燒,說(shuō)明二者都是可燃物。放在銅片兩側(cè)給它們加熱后可看到乒乓球碎片先燃燒,說(shuō)明燃燒需要溫度達(dá)到可燃物的著火點(diǎn)。3.你能利用蠟燭和燒杯(或選擇其他用品)設(shè)計(jì)一個(gè)簡(jiǎn)單實(shí)驗(yàn)證明燃燒需要氧氣(或空氣)嗎?答:點(diǎn)燃兩支相同的蠟燭,然后在一支蠟燭上扣住一只杯子,看到被杯子扣住的蠟燭一會(huì)兒就熄滅,說(shuō)明燃燒的條件之一是需要氧氣。
一、教學(xué)目標(biāo)1.初步掌握“兩邊成比例且?jiàn)A角相等的兩個(gè)三角形相似”的判定方法.2.經(jīng)歷兩個(gè)三角形相似的探索過(guò)程,體驗(yàn)用類比、實(shí)驗(yàn)操作、分析歸納得出數(shù)學(xué)結(jié)論的過(guò)程;通過(guò)畫(huà)圖、度量等操作,培養(yǎng)學(xué)生獲得數(shù)學(xué)猜想的經(jīng)驗(yàn),激發(fā)學(xué)生探索知識(shí)的興趣,體驗(yàn)數(shù)學(xué)活動(dòng)充滿著探索性和創(chuàng)造性.3.能夠運(yùn)用三角形相似的條件解決簡(jiǎn)單的問(wèn)題. 二、重點(diǎn)、難點(diǎn)1. 重點(diǎn):掌握判定方法,會(huì)運(yùn)用判定方法判定兩個(gè)三角形相似.2. 難點(diǎn):(1)三角形相似的條件歸納、證明;(2)會(huì)準(zhǔn)確的運(yùn)用兩個(gè)三角形相似的條件來(lái)判定三角形是否相似.3. 難點(diǎn)的突破方法判定方法2一定要注意區(qū)別“夾角相等” 的條件,如果對(duì)應(yīng)相等的角不是兩條邊的夾角,這兩個(gè)三角形不一定相似,課堂練習(xí)2就是通過(guò)讓學(xué)生聯(lián)想、類比全等三角形中SSA條件下三角形的不確定性,來(lái)達(dá)到加深理解判定方法2的條件的目的的.
