小学英语四种时态复习一提到时态，就必然用到动词。首先要明确两个概念：动词有五种形式，即：原形（形式），第三人称单数（形式），过去式（形式），现在分词（形式），过去分词（形式）。小学阶段，句子有以下四种常见时态，即：一般现在时态；一般过去时态；一般将来时态；现在进行时态。式，意思就是各种不同的形式，是对应着动词来说的；时态，意思就是表达各种不同的时间的事情，是对应着句子来说的。式与时，先搞懂区别。一、一般现在时态一般现在时用法口诀一般现在时，every,usually,often,sometimes.第一、二人称和复数，动词原形不变换。除了I,you，复数外，动词后加s(es)别忘怀。要变一般疑问句，be动词提前很容易。若是没有be动词，Do和Does开头要注意。否定句，很简单，not在be动词后面站。若是没有be动词，do,does加not要牢记。请把这些规律记，一般现在时没问题。一般现在时态，可能是两种意思。第一，表示经常性的动作，常与often,sometimes,usually,everyday,everyweek,everymonth,everyyear等表示频率的副词连用。例如：Heoftengoesswimminginsummer.Iusuallygotoworkbybike.SamvisitsChinaeveryyear.第二，表示现在的状态。如：Mymotherisaworker.Thereisacomputerinourclassroom.注意问题：be(am,is,are)动词就是独立的谓语动词，一个句子中有了be(am,is,are)就有了谓语动词了。句子中不能同时出现两个谓语动词。不少同学经常出这样的错误：Theboyisofteneatshamburgers.（错）应改为：Theboyofteneatshamburgers.二、现在进行时态正在进行时态口诀现在分词用途多，进行时态不用说。它的构成很好记，动词后缀ing。词尾若有哑音e，去e再加没问题。一辅重读闭音节，这个字母要双写。还有一点要注意，改y为i再加ing。现在进行时态，表示现在正在发生的动作。结构是：am/is/are+动词ing（现在分词）形式。如：I’mwritingastory.You/They/Wearecleaningtheclassroom.He/She/Itishavingsomefood.三、一般将来时态一般将来时态用法一般将来时，将要发生事。谓语不一般，will后加动原。要变疑问句，will置主语前。否定句，也不难，will后把not添。一般将来时态，表示将要发生的事情。结构是：am/is/aregoingto+动词原形；或者是will+动词原形。will通用于各种人称之后，不受人称和单/复数变化的影响。如：I/We/You/You/He/She/It/Theywilltakeawalkaftersupper.Iam/Weare/Theyare/Youare/He/She/Itisgoingtohaveawalkaftersupper.四、一般过去时态一般过去式之歌过去式构成有方法，一般词尾加ed。如果词尾有个e，直接加d就可以。辅音字母y在尾，改y为i加ed。“一辅重闭”作尾巴，双写之后ed加。标准过去式加ed，少量不规则分别记。am和is对was，are要变were没问题。have和has用had，do和does变did。动词过去式不规则词(目前学过的)：am—wasis—wasare—weredo—diddoes—didhave—hadhas—hadgo—wentbuy—bought一般过去时态，也有两种意思。第一，表示过去发生的动作，经常与明确的表示过去的时间连用，如：lastweek,yesterday,thedaybeforeyesterday,lastnight,lastyear,lastweekend等。如：Thefamilyhadapicnicintheparklastweekend.第二，表示过去的状态。如：Therewasasmallpondintheschoolbefore.Marywasateachertwoyearsago.注意问题：be(was,were)是独立的谓语动词，它不能与行为动词的过去式同时使用。同学们经常出这样的错误：Itwasrainedyesterday.（错）应改为；Itrainedyesterday.Theduckswereateourpicnic.（错）应改为：Theducksateourpicnic.过去式动词不存在第三人称单数的问题。也就是说，一般过去时态的句子中，无论主语是什么人称，单数还是复数，过去式动词都不能加s/es.专项练习一、用动词的正确形式填空1.I________(do)myhomeworkeveryevening.2.We_______(fly)kitesintheparkonSundays.3.Mymother________(clean)ourroomonSundays.4.Tom_______(play)thepianoeverySaturday.Nowhe______(play).5.She_______(like)swimming.She______(swim)thisweekend.6.Usuallymymother_______(wash)thedishesafterlunch.Butmygrandma_______(wash)today.7.Lookattheman!He______(read)amagazine.8.Look!Theplane________(fly)overthebuilding.9.Listen!Myaunt________(sing)intheroom.Sheisasinger.She_____(like)singing.She_______(have)amusicshow.Sheisexcited.10.TomandMikealways______(swim)intheriver.They_____(swim)intheswimmingpoolthisSunday.Look!They______(swim).11.What______youusually______(do)intheevening?I_______(play)computergames.12.What_______you_______(do)now?I_______(make)apaperplane.13.What_______he_______(do)?He______(dance).14.What_______she______(do)yesterday?She______(visit)hergrandparents.15.______yourmother______(read)newspaperinthemorning?Yes,She________.16._______you_______(like)fishing?No,I______.Ilike______(swim),butmybrother______(like).17.How______yourfather_______(go)toworkeveryday?He______(go)bybike.Butit’scoldtoday.He______(take)theNo.21bus,,andhe_______(go)toworkbytaxiyesterday.18._______themonkey_______(like)climbingtrees?Yes,it_______.19.What_______yourfather______(do)afterlunch?He_______(read)acomicbook.What_____he_______(do)today?He_______(clean)thekitchenformygrandma.Look!He(clean).20.________you______(collect)stamps?Yes.I_______.________yourbrother______(collect),too?No,he________.二、选择题1._____he_____totheparkat6:30inthemorning?No,he_____.A.Does;goes;doesB.Does;go;doesn’tC.Does;go;does2.Whatcolour_____you_____thisbookcase?I_____itpink.A.are;goingtopaint;amgoingtopaintB.do;paint;paintC.did;paint;painted3.Timalways_____apictureathome.He_____acarnow.A.draws;isdrawingB.draw;drawC.draws;draw4.Sheusually_____herfriends.Theyoften_____tea.A.see;drinkB.sees;drinksC.sees;drink5.Heusually_____thedishesatnight,buttonighthe_____clothes.A.wash;washB.washes;isgoingtowashC.iswashing;washes6.Mr.Greenusually_____hisnewspaperintheevening,butheandhiswife_____televisionyesterdayevening.A.reads;watchesB.reads;isgoingtowatchC.reads;watched7.Wherearethemanandthewoman?They_____nearthetree.A.sitB.satC.aresitting8._____yourpenpal_____diving?No,he_____.He______writingstories.A.Does;like;doesn’t;likesB.Does;likes;doesn’t;likeC.Do;like;don’t;likes9._____you_____fishingyesterday?No,we_____.A.Does;go;doesn’tB.Did;go;didn’tC.Do;go;don’t10.Openthewindow,Please.Look!He_____it.A.opensB.isopenningC.isopening11.Iusually_____somemilkeveryday.ButI_____coffeeyesterday.A.drink;drankB.isdrinking;drinkC.drank;amdrinking12.Mr.Greenoften_____hisnewspapersatnight.Buthe_____aninterestingbooktonight.A.reads;readsB.reads;readC.reads;isgoingtoread13.Theoldman_____playingsportsinthepark.He_____morningexercisenow.A.likes;isdoingB.likes;doesC.like;doing14.What_____youusually_____intheevening?I______computergames.What_____you_____lastnight?I_____abook.A.do;do;playB.did;do;playedC.does;do;playsdid;do;readdo;do;readdo;do;amreading
