Hi!朋友们。我是一般过去时，在七年级我已经出现过。先来回顾一下吧！
本单元我们的主要任务是和大家一起学习动词过去式的构成及一般过去时的句型结构。Come on!
◆动词过去式的构成
实义动词的过去式有规则和不规则两种变化。规则动词过去式的变化，可归纳为以下四种形式：
1．一般情况下在动词后直接加-ed，如stay→stayed；look→looked。
2．以不发音字母e结尾的动词去掉e再加-ed，如like→liked；love→loved。
3．以重读闭音节结尾的动词且末尾只有一个辅音字母的，双写最后一个辅音字母再加-ed，如drop→dropped；stop→stopped。
4．以辅音字母加y结尾的动词变y为i，再加-ed，如study→studied；carry→carried。
不规则动词的过去式请同学们注意总结。本单元出现的不规则动词的过去式有：
be→was/ were；have/ has→had；do/ does→did；go→went；eat→ate；hang→hung；see→saw；buy→bought；win→won；get→got；meet→met；take→took；sleep→slept；come→came；put→put；read→read(注意read的原形和过去式的发音不同)
◆一般过去时的句型结构
1．含be动词的一般过去时句型结构
肯定句：主语+was/ were+表语+其它成分
否定句：主语+was/ were + not+表语+其它成分
一般疑问句：Was/ Were +主语+表语+其它成分
肯定回答：Yes， 主语+was/ were
否定回答：No， 主语+wasn’t/ weren’t
请看下面的例句：
She was an English teacher.
She wasn’t an English teacher.
—Was she an English teacher？
—Yes，she was./ No，she wasn’t.
2．含行为动词的一般过去时句型结构
行为动词的过去式作谓语时没有人称和数的变化。
肯定句：主语+动词过去式+其它成分
否定句：主语+didn’t+动词原形+其它成分
一般疑问句：Did+主语+动词原形+其它成分
肯定回答：Yes， 主语+did
否定回答：No， 主语+didn’t
请看下面的例句：
He worked in this factory in 2003.
He didn’t work in this factory in 2003.
—Did he work in this factory in 2003？
—Yes，he did./ No，he didn’t.
3．一般过去时的特殊疑问句结构
（1）疑问词在句中不充当主语时，句型结构为：疑问词+一般疑问句。例如：
When did you study in this school？
（2）疑问词在句中充当主语时，句型结构为：疑问词+行为动词的过去式(或was/ were+表语)+其它成分。例如：
Who was your English teacher？
