小学一般过去时.doc

一般过去时一一般过去时的用法1.一般过去时表示过去某个时间发生的动作或存在的状态，常和表示过去的时间状语连用。2. 常用时间状语：yesterday, last night, two days ago, in 2000,at that time, before liberation，when 等引导的含过去时的句子。二一般过去时的结构1.有be 动词时句子的结构肯定句：主语 + was/were + 其他 e.g. She was here yesterday.否定句：主语 + wasnt/were + 其他 e.g. She wasnt here yesterday.一般疑问句：Was/Were + 主语 + 其他 e.g. Was she here yesterday.特殊疑问句：特殊疑问词 + was/were + 主语 + 其他。 e.g. Where was she yesterday ?练习：用be动词的适当形式填空。1. I _ at school just now.2. He _ at the camp last week.3. We _ students two years ago.4. Yang Ling _ eleven years old last year.5. There _ an apple on the plate yesterday.6. There _ some milk in the fridge on Sunday.小结：Be动词在一般过去时中的变化：am 和is在一般过去时中变为was。（was not=wasnt）are在一般过去时中变为were。（were not= werent）带有was或were的句子，其否定、疑问的变化和is, am, are一样，即否定句在was或were后加not，一般疑问句把was或were调到句首。2.没有be动词时的句子结构肯定句：主语+动词的过去式+其它。e.g. He went to the toy store yesterday. 他昨天去玩具店了。 否定句：主语+did not (didnt)+动词原形+其它。e.g. He didnt go to the toy store yesterday. 他昨天没去玩具店。一般疑问句：Did+主语动词原形其它？e.g. -Did he go to the toy store yesterday ? -Yes, we did./No, we didnt.特殊疑问句：特殊疑问词did+主语动词原形其它？e.g. He went to the toy store. （就画线部分提问） -Where did he go yesterday ?【经典例题分析】【例1】1. They _ on the farm a moment ago.注意：a moment ago是一刻钟之前，是过去时间语；on the farm表示的是状态，用be动词；They是跟be动词are, 因此是填are的过去式。【例2】2. I did my homework at 9 oclock yesterday evening.(改一般疑问句) 注意：理解一般疑问句的定义，然后分析句子时态，最后准确地表达句子。练习：按要求改写句子。1. It was exciting.否定句：_ _一般疑问句：_ _肯、否定回答：_ _3Mike took a trip on his holiday ?（对划线部分提问） 三动词过去式变化规则1一般在动词末尾加-ed， e.g. pull-pulled, cook-cooked2结尾是e加d， e.g. taste-tasted like-liked3末尾三个字母是以“辅音+ 元音 + 辅音”结尾的重读闭音节，应双写末尾的辅音字母，再加-ed，e.g. stop-stopped 4以“辅音字母+y”结尾的，变y为i， 再加-ed, e.g. study-studied5.不规则变化的动词：sad-said see-saw ride-rode swim-swam teach-taught【拓展】动词的不规则变化：costcost（花费） cutcut （割） hithit （打）hurthurt伤害 letlet（让） putput（放）readread（读） beatbeat（跳动） becomebecame（变成）comecame（来） runran（跑） digdug（挖）getgot（得到） hanghanged（吊死） hanghung（悬挂）holdheld（抓住） shineshone（照耀） sitsat（坐）winwon（赢） meetmet（遇见） keepkept （保持）sleepslept（睡） sweepswept（扫） feelfelt（感觉） smellsmelt（闻） leaveleft（离开） buildbuilt（建设）lendlent（借出） sendsent（传送） spendspent（花费）loselost （丢失） burnburnt（燃烧） learnlearnt（学习）meanmeant（意思是） catchcaught（抓住） teachtaught（教）bringbrought（带来） fightfought（战斗） buybought（买） thinkthought（想） hearheard（听见） sellsold（卖） telltold（告诉） saysaid（说） findfound（找到）have/hashad（有） makemade（制造） standstood（站），understandunderstood（明白） beginbegan（开始），drinkdrank （喝） ringrang（铃响） singsang（唱），swimswam（游泳） blowblew（吹） drawdrew（画），flyflew（飞） growgrew（生长） knowknew（知道），throwthrew（投掷） breakbroke（打破） speakspoke（说，讲），choosechose（选择） forgetforgot（忘记） wakewoke（醒）， eatate（吃） fallfell（落下） givegave（给）， riserose（升高） drivedrove（驾驶） riderode（骑），writewrote（写） dodid（做） gowent（去），lielay（平躺） seesaw（看见） wearwore（穿），taketook（取） mistakemistook（弄错）3.同步教学辅导练习一、用所给的动词的适当形式填空。1.
