《初中英语时态》教学设计学习目标：能初步掌握初中英语中的6种时态学习重点：理解时态中动词的不同形式应用学习难点：现在完成时态学情分析：时态在初中英语中是重点，并有一定的难度，初二学生学习起来有一定的难度，教师通过比较、习题突破。教学步骤：一、想一想：用play的正确形式填空：1.He___basketballeveryday.2.He___basketballnow.3.He___basketballtomorrow.4.He___basketballyesterday.5.He___basketballatthreeyesterdayafternoon.6.He___basketballforthreeyears.二、初中阶段8种时态：1.一般现在时2.现在进行时3.一般将来时4.一般过去时5.过去进行时6.现在完成时 1.过去完成时（暂时不做要求）2.过去将来时（暂时不做要求）一、一般现在时:1.表示经常反复发生的动作.e.g.Theyoftenspendtheirholidaysinthesouth.常搭配的时间状语:alwaysoftenusuallysometimesseldom(很少）neverfromtimetotimeeverydayevery….onceaweek2.表示状态:e.g.Heisbusyatthemoment.3.表示客观真理,谚语,格言.e.g.Thesunrisesintheeast.4.用与时间或条件状语从句中,代替一般将来时:e.g.Iwillbehappyifyoucome.Wewillgowhenhecomes.二、现在进行时1.表示说话时正在进行的动作.e.g.Heisplayingbasketball.2.表示目前一阶段正在进行(但说话时不一定在进行)的动作:e.g.Wearepreparingforanexamthesedays.一般现在时与现在进行时的区别1.进行时强调动作正在进行,而现在时强调动作的经常和反复,或特征,这类动作没有时间性的. 1.某些表示感官知觉的动词如:see,hear,smell,taste等表示感觉,用一般时,不用进行时.e.g.Canyouseeaplaneinthesky?注意:1)feel可以用一般时和进行时表示说话时的感觉:e.g.Howareyoufeelingtoday?Ifeeltired.2)see,hear有相应表示动作的动词lookat/listento,这些词可以用进行时比较:Canyouseeamaponthewall?Heislookingatamaponthewall.3.有些表示状态或心理感觉的动词一般不用现在进行时,而用一般现在时表示状态或感觉,如love,like,hate,want,need,wish,know(知道),understand(懂得),remember(记得),believe,mean(意味着),think(认为),feel(认为),fit(合适),find(认为),show(表明),have(有)e.g.Iknowyouareright.Iwanttovisitthemtomorrow.HelikesEnglish.当堂训练:1.Water______(freeze结冰)atthetemperature0.2.Theair_____(keep)movingallthetime.3.Thetown_____(lie)tothewestofthehill.4.I_______(believe)youareright.5.--____myson__________(work)hardthisterm?--Oh,yes,he_________(try)hisbestnow.6.______thehat_______(fit合适)mewell?7._____they________(clean)theclassroomnow?三、一般将来时：相对于讲话时间将要发生的动作或情况 常用的时间：tomorrow，nextweek，thedayaftertomorrow，sooninthefuture，in+一段时间...Eg.1)Shewillgototheparktomorrow.2)Iwillreturnhomenextweek.3)---Whatareyougoingtodothisevening?---Iamgoingtodomylessons.四、一般过去时1.表示过去某一具体时间发生过的动作.e.g.Ididmyhomeworklastnight.注意:1)有时句中虽然没有表示确定过去时间的状语,但根据上下文情景可以推断出是过去发生过的动作,此时也应用一般过去时e.g.Iwassorrytolearnofyourillness.Ididn’tknowhewasyourfather.2)描述已故之人的动作或状态用一般过去时.e.g.Edisoninventedtheelectriclight.2.表示过去经常反复发生的动作.Heoftenswamwhenhewasyoung.3.表示主语过去的状态或特征.e.g.Itwasrainylastweek.Hewasataxidrivermanyyearsago.练一练：1.–WhathappenedtoMary?--She______(fall)offherbikeand____(hurt)herself2.Sam____(live)inthesmalltownforfiveyearsduringthewar.3.Ithasbeen3yearssinceI____(see)youlasttime.4.Hewon’ttelluswherehe______(get)thebook. 五、过去进行时1.表示过去某一时刻正在进行的动作.e.g.Hewasdoingshoppingthistimeyesterday.Wewerehavingadiscussionatthattime.2.表示过去某一阶段正在进行的动作.e.g.Peterwasplayingchessthewholeafternoonyesterday.Wewerehavingameetingfromninetoelevenyesterday.3.用与when,while,as引导的表示过去的从句:(注意,这样的动词必须可以持续)e.g.WhileIwaswatchingTV,thetelephonerang.Aswewereleaving,someofourfriendsarrived.Whenwewereplayingontheplayground,itbegantorain.过去进行时与一般过去时的区别:过去进行时强调过去某时刻或阶段动作的进行,不表明动作的完成,而一般过去时表示过去某动作已发生,表明动作已完成.e.g.Hewaswritingacompositionlastnight.(作文不一定完成)Hewroteacompositionlastnight.(作文肯定写完了)六、现在完成时I.构成：助动词have/has+动词的过去分词II.用法：1.表示某一个动作对现在的影响和结果。e.g.Ihavealreadyfinishedmyhomework.Theyhaveboughtanewhouse.常用的时间状语：already,just,yet2.表示从过去某一时间开始，一直持续到说话时，而且动作还在延续，常与“for+时间段”或“since+时间点”的时间状语连用。 e.g.WehavelearnedEnglishforfiveyears/since2012.Hehastaughtheresincehecamehere.三、比较分析e.g.TheGreenshavestayedinChinaforayear.TheGreensstayedinChinaforayearduringthewar.Ihavelearnedcomputerforsometime.IlearnedcomputerforsometimewhileIwasinBeijing.Isawthisfilmyesterday.（只说明动作发生在过去。）Ihaveseenthisfilm.（强调对现在的影响，电影的内容已经知道了。）　ShehasreturnedfromParis.　（她已从巴黎回来了。）Shereturnedyesterday.（她是昨天回来的。）HehasbeenintheLeagueforthreeyears.(在团内的状态可延续)HejoinedtheLeaguethreeyearsago.　(三年前入团，joined为短暂行为。)四、想一想：现在你会做了吗？用play的正确形式填空：1.He______basketballeveryday.2.He________basketballnow.3.He________basketballtomorrow.4.He______basketballyesterday.5.He__________basketballatthreeyesterdayafternoon.6.He_________basketballforthreeyears.小结2
