Therewas/were核心含义Therewas/were是Therebe句型的一般过去式形式专门用于描述过去某个时间、某地存在或不存在的人或事物侧重表达“过去有/没有”，区别于Thereis/are的现在存在含义常搭配inthepast、tenyearsago、justnow等过去时间状语Therewas/werebe动词搭配规则be动词的选择由后面的名词单复数/类别决定，与现在时一致后接单数名词或不可数名词，用was后接复数名词，用were无需考虑地点，仅以名词的数为判断依据，这是核心原则Therewas/were句式结构表句式类型基本结构核心要点肯定句Therewas/were+名词+地点名词决定was/were，地点表位置否定句Therewasn't/weren't+名词+地点was+not=wasn't，were+not=weren't疑问句Was/Werethere+名词+地点？be动词提至句首，句末用问号Therewas/were肯定句用法肯定句用于陈述过去某地有某物/某人，结构简单直接名词为单数/不可数时用was，示例：Therewasarivernearthevillage.名词为复数时用were，示例：Thereweremanytreesintheparkthen.时间状语可放在句首或句末，不改变句子核心结构Therewas/were否定句用法否定句表达过去某地没有某物/某人，直接在be动词后加notwas的否定是wasn't，were的否定是weren't，无其他变形示例：Therewasn'tahospitalinthistowntenyearsago.示例：Thereweren'tanybooksonthedeskjustnow.Therewas/were疑问句及回答疑问句将Was/Were提至句首，there紧跟其后，语序简单单数/不可数名词用Was提问，复数用Were提问肯定回答：Yes,therewas/were.否定回答：No,therewasn't/weren't.示例：Wasthereaparkhere?—Yes,therewas.一般过去时核心含义一般过去时是描述过去的基础时态，应用范围极广可表达过去某个时间发生的一次性动作，动作已结束也可表达过去存在的状态或习惯性的动作必须搭配过去时间状语，这是判断该时态的关键标志一般过去时常见时间状语时间状语是一般过去时的“识别标签”，需熟记分类单个时间：yesterday,yesterdaymorning/afternoon段时间：lastweek/month/year,in2000,inthepast其他：justnow,amomentago,attheageof6一般过去时基本句式结构肯定句：主语+动词过去式+其他，直接用过去式表动作否定句：主语+didn't+动词原形+其他，借助didn't表否定疑问句：Did+主语+动词原形+其他？，借助Did提至句首否定和疑问句中，动词必须恢复原形，这是高频考点动词过去式规则变化1一般情况：直接在动词词尾加-ed，这是最基础的变化形式清辅音后读/t/，例：work→worked,look→looked浊辅音/元音后读/d/，例：play→played,live→lived此类变化占比最高，只需直接加词尾，无需改变单词本身动词过去式规则变化2以不发音的e结尾：直接加-d，省略重复的e，简化拼写例：like→liked,dance→danced,use→used以“辅音字母+y”结尾：变y为i，再加-ed例：study→studied,carry→carried,worry→worried动词过去式规则变化3重读闭音节结尾：双写末尾的辅音字母，再加-ed判断标准：辅+元+辅结尾，且最后一个音节重读例：stop→stopped,plan→planned,skip→skipped初中阶段掌握常见的此类动词即可，无需过度拓展动词过去式高频不规则变化不规则变化无固定规律，需单独记忆，是学习重点高频词：go→went,see→saw,eat→ate,do→did,have→had,win→wontell→told,get→got,make→made语法拓展不规则动词过去式巧记A-B-B型：have-had,get-got,make-madeA-B-C型：go-went-gone,see-saw-seen,eat-ate-eaten语法小练单项选择1.There______abigtreeinfrontofourhouselastyear.A.wasB.wereC.is2.I______afilmwithmysisteryesterdayevening.A.watchB.watchedC.watches3.______thereanybirdsinthetreejustnow?A.WasB.WereC.Are4.They______tothesupermarketlastSunday.A.goB.wentC.going5.He______hishomeworkanhourago.A.finishB.finishedC.finishesABBBB6.There______anymilkinthebottleamomentago.A.wasn'tB.weren'tC.isn't7.Didyou______breakfastthismorning?A.haveB.hadC.having8.She______astorytoherlittlebrotherlastnight.A.tellB.toldC.tells9.What______you______attheageof7?A.do;doB.did;doC.are;doing10.They______notgotoschoolyesterdaybecauseoftherain.A.doB.didC.areAABBB11.There______manyflowersinthegardeninspringlastyear.A.wasB.wereC.are12.I______anewpenonmywayhomeyesterday.A.findB.foundC.finds13.Wastherealibraryinyouroldschool?—No,______.A.therewasn'tB.thereweren'tC.itwasn't14.He______veryhardwhenhewasastudent.A.studyB.studiedC.studies15.We______agoodtimeatthepartylastnight.A.haveB.hadC.havingBBABB语法小练用所给词适当形式填空1.There______(be)abookonthedeskfiveminutesago.2.Myfather_________(work)inafactorytenyearsago.3.There___________(notbe)anywaterintheglassjustnow.4.She______(see)abeautifulbirdinthetreeyesterday.5.______(do)you______(go)totheparklastweekend?wasworkedwasn'tsawDidgo
