一、 一般过去时的定义
一般过去时表示过去某一时候或某一段时间所发生了的事情或存在的状态。常与过去时间yesterday, this morning, just now, a moment ago, in May, last night / year / week, once upon a time, the other day, just now ,, since的从句 in +过去年代
二、有时用一般过去时也是时态一致的需要。
如：I didn’t know you were here. 没想到你在这里。
三：1. 表示一系列的动作，尽管有先后，都用一般过去时，最后两个动词之间用and连结。如： He opened the door, rushed out and then disappeared. 他打开门，冲了出去，然后就消失了。
三、 一般过去时对谓语动词的过去式构成。分规则变化和不规则变化两种形式，不规则变化通常需要逐个记忆，规则变化则遵循以下原则：
(1) 一般在动词后加-ed。如：play—played, offer—offered, weigh—weighed, destroy— destroyed, sign—signed.
(2) 在以字母e结尾的动词后，只加-d。如：like—liked, provide—provided, hate — hated, date—dated。
(3) 在以“辅音字母+y”结尾的动词后，则改y为i，再加—ed。如： study— studied.
(4)双写最后辅音字母，再加-ed。如：plan—planned, refer—referred, regret—regretted, stop-stopped
第一部分：知识讲解
1．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。（were not=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放到句首。
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：Who went to home yesterday?
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,      buy-bought
 swim-swam,      sit-sat          bring--brought        can-could         cut-cut
 become-became   begin-began      draw-drew             feel-felt         find-found
 forget-forgot   hear-heard       keep-kept             know-knew
