Period5(SectionB3a-SelfCheck)設計說明本課時的重點是寫作。完成3a任務，讓學生了解如何描述一種食物的制作過程。在完成3b時，引導學生復習如何區分可數名詞與不可數名詞，以及“Howmany/Howmuch...?”的用法。這樣既能對已學知識有所復習，又能讓學生找準寫作的方向，然后順理成章地完成3c的寫作。最后完成SelfCheck，鞏固單元語法。教學目標1.知識目標：(1)指導學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中的練習題來全面復習howmuch和howmany的用法。2.能力目標：能熟練運用祈使句描述一種食物的制作過程。3.情感目標：通過食物制作過程的介紹，讓學生認識到勞動成果來之不易，使之懂得不能浪費食物，珍惜他人的勞動成果。重點難點1.重點：正確運用祈使句描述自己所喜歡的一種食物的制作方法。2.難點：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。教學準備多媒體課件教學過程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，First，wash，Next，cut，cook，Finally，enjoy(6)CooperativeinquiryDiscussthefollowinglanguagepointsandfillintheblanks.Youneedtohavericenoodles，chickensoup，chicken，lettuceandeggs.此句中，need作實義動詞，意為“需要”。其后可跟名詞、代詞、動詞-ing形式或動詞不定式。need還可用作情態動詞，意為“需要”，其后跟動詞原形，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。—MustIfinishmyhomeworknow?我現在必須完成作業嗎?—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：(1)要使用表示順序的詞：first，then，next，afterthat，finally。(2)應注意正確運用祈使句來表達。(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.當堂達標(見導學案“當堂達標”)答案與解析：Ⅰ.1.Dyogurt是不可數名詞，沒有復數形式，也不能用howmany提問，故排除A、C兩項；不可數名詞前通常用“表示量的名詞+of”來表示數量，對不可數名詞前表示量的名詞進行提問時要用howmany，故選D。2.Cbread是不可數名詞，“一片面包”為apieceofbread，“兩片面包”為twopiecesofbread。3.A“It’stimetodosth.”是固定句型，意為“到做某事的時間了”，故選A。4.Btomakethisdeliciousfood構成動詞不定式短語，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。我有點兒冷。open作動詞時，意為“打開”，其反義詞是close(關上)；祈使句的否定形式是在謂語動詞前直接加don’t。由句意可知選C。6.C祈使句的否定形式是在謂語動詞前直接加don’t。Ⅱ.1.snows時態承接上文，用一般現在時；主語是it，所以謂語動詞應用第三人稱單數形式。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；過去的時候”，由此可知本句應用一般過去時；find的過去式為found。4.mixed承接上文時態，要用一般過去時。5.scientistsscientist意為“科學家”，是可數名詞；some后跟可數名詞復數形式。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可知下文的觀點與上文觀點相反。故填disagree。句意為“有些人不同意”。Ⅲ.1~5AEBDCStep8HomeworkReviewthenewwordsandphrasesinthisunit.板書設計UNIT8Howdoyoumakea
