.一般过去时1 内涵：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。一般过去时也表示过去经常或反复发生的动作。be用was或用were,have,has变had；谓语动词过去式，过去时间作标志；一般动词加-ed，若是特殊得硬记2Be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。be的过去时有四巧：一是时间状语巧，表示过去的短语要记牢；二是形式巧，单数was，复数were；三巧是否定句结构，not紧跟waswere；四是疑问句式巧，waswere向前跑(提前)。yesterday或以其构成的短语：yesterdaymorning(afternoon,evening)等；由“last+一时间名词”构成的短语：lastnight,lastyear(winter,month,week)等；由“时间段+ago”构成的短语：amomentago,ashorttimeago,anhourago等；【一巧】时间状语（即标志词）巧。一般过去时表示过去发生的动作或存在的状态，恰巧与表示过去的一些时间状语连用。【二巧】形式巧。例如：Iwasintheclassroomyesterdaymorning昨天早上我在教室里。Theywereoverthereamomentago刚才他们在那边。【三巧】否定句结构巧。与动词be的一般现在时一样，它在动词后面加not即可变成否定句，并且was,were与not可以缩写成wasnt,werent。即：主语wasntwerent表语其他。例如：Iwasnot(wasnt)hereyesterday昨天我不在这儿。Myparentswerenot(werent)athomelastSunday【四巧】疑问句式巧。把was,were提到句首，句末用问号即可变为一般疑问句。即：Was(Were)主语表语其他？例如：Wereyouathomethedaybeforeyesterday前天你在家吗？肯定回答用“Yes,主语waswere”Yes,Iwas.否定回答用“No,主语wasntwerent”No,Iwasnt.3句中没有be动词的一般过去时的句子，要借助动词did否定句：didnt +动词原形，如：Jim didnt go home yesterday.一般疑问句：在句首加did，句子中的动词过去式变原形。如：Did Jim go home yesterday?特殊疑问句：疑问词+did+主语+动词原形？如： What did Jim do yesterday?疑问词当主语时：疑问词+动词过去式？如： Who went to home yesterday?动词过去式变化规则：1一般在动词末尾加-ed，如：pull-pulled, cook-cooked2结尾是e加d，如：taste-tasted3末尾只有一个元音字母和一个辅音字母的重读闭音节，应双写末尾的辅音字母，再加-ed，如：stop-stopped4以“辅音字母+y”结尾的，变y为i， 再加-ed，如：study-studied5不规则动词过去式：am,is-was, are-were, do-did, see-saw, say-said, give-gave, get-got, go-went, come-came, have-had, eat-ate, take-took, run-ran, sing-sang, put-put, make-made, read-read, write-wrote, draw-drew, drink-drank, fly-flew, ride-rode, speak-spoke, sweep-swept, swim-swam, sit-sat2过去某个时间存在的状态例：Jimwas12yearsold.过去经常或反复发生的动作例：Heoftenwenttoswimwhenhewasachild.2.与一般过去时连用的时间状语常见的有：Yesterday,lastnight,in1990,once,twodaysago,thedaybeforeyesterday,theotherday几天前3.一般过去时的四个基本句型谓语动词是be谓语动词是do肯定句Hewasintheroomyesterday.否定句Hewasnotintheroomyesterday.一般疑问句-Washeintheroomyesterday?-Yes,theydid.No,theydidnt.特殊疑问句Wherewasheyesterday?肯定句TheywatchedTVyesterday.否定句TheydidntwatchTVyesterday.一般疑问句-DidtheywatchTVyesterday?-Yes,hewas.No,hewasnt.特殊疑问句Whatdidtheydoyesterday?4. 动词的过去式和过去分词的规则变化一般在动词词尾加ed例:wantwanted以e结尾的动词，只加d例:livelived以辅音字母加y结尾的动词，改y为i，再加ed例:studystudied以重读闭音节结尾，末尾只有一个辅音字母，双写这一辅音字母，再加ed例:stopstopped1. 单项选择：从下列各题后所给的四个选项中选择最佳答案填空。2.
