Period5(SectionB3a-SelfCheck)設(shè)計(jì)說明本課時(shí)的重點(diǎn)是寫作。完成3a任務(wù)，讓學(xué)生了解如何描述一種食物的制作過程。在完成3b時(shí)，引導(dǎo)學(xué)生復(fù)習(xí)如何區(qū)分可數(shù)名詞與不可數(shù)名詞，以及“Howmany/Howmuch...?”的用法。這樣既能對已學(xué)知識有所復(fù)習(xí)，又能讓學(xué)生找準(zhǔn)寫作的方向，然后順理成章地完成3c的寫作。最后完成SelfCheck，鞏固單元語法。教學(xué)目標(biāo)1.知識目標(biāo)：(1)指導(dǎo)學(xué)生利用課堂上所獲取的知識來仿寫一篇短文，介紹自己所喜歡的一種食物的做法。(2)通過完成SelfCheck中的練習(xí)題來全面復(fù)習(xí)howmuch和howmany的用法。2.能力目標(biāo)：能熟練運(yùn)用祈使句描述一種食物的制作過程。3.情感目標(biāo)：通過食物制作過程的介紹，讓學(xué)生認(rèn)識到勞動(dòng)成果來之不易，使之懂得不能浪費(fèi)食物，珍惜他人的勞動(dòng)成果。重點(diǎn)難點(diǎn)1.重點(diǎn)：正確運(yùn)用祈使句描述自己所喜歡的一種食物的制作方法。2.難點(diǎn)：能用課堂上所獲取的知識介紹自己所喜歡的一種食物的制作方法。教學(xué)準(zhǔn)備多媒體課件教學(xué)過程Step1Warmingup1.RetellthearticleinSectionB2b.2.Here’sarecipeforagreatturkeysandwich!Completetheinstructionswiththewordsinthebox.turkey，finally，butter，tomato，then，putFirst，putmustard(芥末醬)ontwoslices(薄片)ofbread.Then，cutuponetomato.Putthetomatoonthebread.Next，addtwoslicesofturkey.Finally，puttwospoonsofbutterontheturkey.Step2Presentation1.Leadingin.T：WhatdoweChineseeatonourbirthdays?Ss：Wealwayseatnoodles.T：ThereisaveryspecialkindofricenoodlesinYunnan.Doyouknowthenameofit?Ss：Yunnanricenoodles.T：Good.Doyouknowhowtomakericenoodles?Now，pleaselookat3a.2.Workon3a.(1)Havethestudentscovertheboxandlookatthepassage.(2)Elicitthepossiblewordsforeachoftheblanks，onebyonefromthestudents.(3)Writethewordsontheblackboard，andexplaintothestudentswhytheirguessescouldbecorrectorincorrectfromagrammaticalpointofview.(4)Havethestudentsuncovertheboxandfillintheblanks.(5)Checktheanswers.Answers：have，F(xiàn)irst，wash，Next，cut，cook，F(xiàn)inally，enjoy(6)CooperativeinquiryDiscussthefollowinglanguagepointsandfillintheblanks.Youneedtohavericenoodles，chickensoup，chicken，lettuceandeggs.此句中，need作實(shí)義動(dòng)詞，意為“需要”。其后可跟名詞、代詞、動(dòng)詞-ing形式或動(dòng)詞不定式。need還可用作情態(tài)動(dòng)詞，意為“需要”，其后跟動(dòng)詞原形，多用于否定句或疑問句中。Youneedtoclean(clean)theroomeveryday.你需要每天打掃房間。Heneedn’tcomeatonce.他不必馬上來?！狹ustIfinishmyhomeworknow?我現(xiàn)在必須完成作業(yè)嗎?—No，youneedn’t.不，你不必。(7)Readagain，andtrytoretelltheprocessofmakingricenoodles.Step3Practice1.Thinkofafavoritefoodinyourhometown.Makealistofingredients.IngredientswatermelonapplebananahoneyyogurtAmountonetwothreeonespoontwospoons2.Studentschangetheirlistswiththeirpartners，andthenaskandanswerinpairs.Forexample：S1：Howmanytomatoesdoyouneed?S2：Three.S1：Howmuchsugardoyouneed?S2：Twospoons....Step4Writing1.Writearecipeforyourfavoritefood.Use3aand3btohelpyou.寫作指導(dǎo)：(1)要使用表示順序的詞：first，then，next，afterthat，finally。(2)應(yīng)注意正確運(yùn)用祈使句來表達(dá)。(3)合理利用3a、3b積累的語言素材。2.Letsomestudentsreadtheirpassagestotheclass.Samplewriting：Itisveryeasytomakeyourowndeliciousburger.Youneedbeef，breadbuns，lettuce，onionsandsauce.First，cutthebreadbunandcookit.Next，cutthelettuceandonions.Putsomelettuceandonionsonthebunandaddsomesauce.Then，useyourhandstoshapethebeefintoaball.Next，flattentheballofbeeftoformabeefpatty.Then，cookthepattyonbothsides.Finally，putthepattyonthebottomhalfofthebun，addmorelettuce，onionsandsauce，andputtheotherhalfofthebunontop.Enjoyyourburger!Step5ExpansionandExtensionWorkon4.1.T：Ilikebeefandtomatosoupverymuch.Doyouknowhowtomakethiscrazyfood?(Showtheprocessofmakingbeefandtomatosouponthescreen.)First，cutuptomatoesandsomebeef.Next，puttheminthewater.Then，addsomerelishandsalttothesoup.Finally，boilthesoup.2.Askthestudentstomaketheirowncrazyfoodinpairs.Step6SelfCheck1.WorkonSelfCheck1.(1)Readandtranslatethesentences.(2)Numbertheinstructions.(3)Completetheinstructionswiththewordsinthebox.(4)Checktheanswers.Answers：4Finally，mixeverythingtogetherandserveit.3Then/Next，cookforfiveminutesandaddtwoeggs.1First，cutupthreetomatoesandputthemintoapot.2Next/Then，addsomewater，sugarandsalt.2.WorkonSelfCheck2.(1)Revisetheuseofhowmanyandhowmuch.(2)Writequestionsandanswersusingthewordsinthebrackets.(3)Checktheanswers.Answers：1.A：Howmanyeggsdoweneedtomakeacake?B：Weneedtwoeggs.2.A：Howmuchmilkdoweneed?B：Weneedthreecupsofmilk.3.A：Dowehavetoaddsugarorhoney?B：Yes，wecanaddtwospoonsofhoney.(4)Studentsrole-playtheconversationsinpairs.Step7Summary1.Learnhowtodescribeafoodproductionprocess.2.Distinguishcountablenounsanduncountablenounscorrectly，andcanusethestructureof“Howmany/much...?”.3.Releasecommandwiththeimperativesentence.4.Useadverbsofsequencecorrectly.當(dāng)堂達(dá)標(biāo)(見導(dǎo)學(xué)案“當(dāng)堂達(dá)標(biāo)”)答案與解析：Ⅰ.1.Dyogurt是不可數(shù)名詞，沒有復(fù)數(shù)形式，也不能用howmany提問，故排除A、C兩項(xiàng)；不可數(shù)名詞前通常用“表示量的名詞+of”來表示數(shù)量，對不可數(shù)名詞前表示量的名詞進(jìn)行提問時(shí)要用howmany，故選D。2.Cbread是不可數(shù)名詞，“一片面包”為apieceofbread，“兩片面包”為twopiecesofbread。3.A“It’stimetodosth.”是固定句型，意為“到做某事的時(shí)間了”，故選A。4.Btomakethisdeliciousfood構(gòu)成動(dòng)詞不定式短語，在句子開頭作目的狀語；needtodosth.意為“需要做某事”。故選B。句意：要制作這種美味的食物，你需要先把蔬菜洗一洗。5.C句意：請不要開窗。我有點(diǎn)兒冷。open作動(dòng)詞時(shí)，意為“打開”，其反義詞是close(關(guān)上)；祈使句的否定形式是在謂語動(dòng)詞前直接加don’t。由句意可知選C。6.C祈使句的否定形式是在謂語動(dòng)詞前直接加don’t。Ⅱ.1.snows時(shí)態(tài)承接上文，用一般現(xiàn)在時(shí)；主語是it，所以謂語動(dòng)詞應(yīng)用第三人稱單數(shù)形式。2.impossible句意：在冬天不可能得到各種新鮮的蔬菜。3.foundintheolddays意為“從前；過去的時(shí)候”，由此可知本句應(yīng)用一般過去時(shí)；find的過去式為found。4.mixed承接上文時(shí)態(tài)，要用一般過去時(shí)。5.scientistsscientist意為“科學(xué)家”，是可數(shù)名詞；some后跟可數(shù)名詞復(fù)數(shù)形式。6.health名詞所有格修飾名詞或名詞短語；people’shealth意為“人們的健康”。7.disagree由but可知下文的觀點(diǎn)與上文觀點(diǎn)相反。故填disagree。句意為“有些人不同意”。Ⅲ.1~5AEBDCStep8HomeworkReviewthenewwordsandphrasesinthisunit.板書設(shè)計(jì)UNIT8Howdoyoumakea
