小学一般过去时教学课件

　　2.Be动词在一般过去时中的变化：⑴am 和is在一般过去时中变为was。（was not=wasn’t）⑵are在一般过去时中变为were。（werenot=weren’t）⑶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。

　　3.句中没有be动词的一般过去时的句子否定句：didn’t +动词原形，如：Jim didn’t go home yesterday. 一般疑问句：在句首加did，句子中的动词过去式变回原形。如：Did Jim go home yesterday? 特殊疑问句：⑴疑问词+did+主语+动词原形?如： What did Jim do yesterday? ⑵疑问词当主语时：疑问词+动词过去式?如：Whowent 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-cooked

　　2）结尾是e加d，如：taste-tasted

　　3）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-stopped

　　4）以“辅音字母+y”结尾的，变y为i，再加-ed，如：study-studied

　　5）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-sat

　　4.句中be动词和动词一般情况下只能有一种而且也必须有一种。如：

　　Theyvisited my parents last weekend .

　　5.一般过去时中的be动词：一般用过去式：was were

　　was用于第一人称单数（I）和第三人称单数（he she it和其他人名或称谓，如：Ben 、 his sister等）；were用于第二人称单数（you）和所有复数（包括第一人称复数we、第二人称复数you；第三人称复数they和其他复数，如the children 、 his parents等）。

　　6.一般过去时中的`动词：一般只有一种情况：+ed

　　这里强调一点，和一般现在时不同的是这里不管主语是第几人称，也不管是单数和复数都加ed。

　　7.一般过去时判断依据（如何判断一个句子是一般过去时）：

　　be动词是was、were

　　动词加ed

　　有表示过去的时间状语

　　现在学过的常用的表示过去的时间状语有：

　　just now amoment yesterday last week last night last weekend last year last month threedays ago two weeks ago.
