【语法】
一般过去时的用法
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。如：last year, yesterday等；也可表示过去经常反复发生的动作，常和often, always等频率副词连用。
例如：I saw him in the street yesterday. 昨天我在街上看见他了。
Li Mei always went to school on foot last year. 去年李梅总是步行上学。
注意：也可以用“used to +动词原形”表示过去经常或反复的动作。
eg. We used to get up early. 我以前总是早起。（意指现在不早起了）
1.一般过去时的形式：
动词be: 第一人称单数和第三人称单数用was, 其余的人称一律用were。
动词have: 一律用had, 没有人称和数的变化。
行为动词：一律用过去式，没有人称和数的变化，行为动词的过去式有两类，一类是规则动词，另一类是不规则动词。
2.一般过去时的几种句型（这里只讲行为动词）
　　肯定句结构为：主语+动词的过去式+其他。如：He went to the toy store yesterday. 他昨天去玩具店了。
　　否定句结构为：主语+did not (didn’t)+动词原形+其他。如：He didn’t go to the toy store yesterday. 他昨天没去玩具店。
　　一般疑问句的构成：Did+主语＋动词原形＋其他？如：
　　1) -Did you go to Beijing last week? -Yes, we did. (No, we didn't.)
　　2) -Did you meet the businessman before? -No, I didn't. (Yes, I did.)
　　特殊疑问句的构成：疑问词＋did+主语＋动词原形＋其他？如：
　　1) -What did you do last night? -I did my homework.
　　2) -Where did you go last week? -I went to Shanghai with my parents.
一般过去时口诀
　　一般过去时并不难，表示过去动作、状态记心间。
　　动词要用过去式，时间状语句末站。
　　否定句很简单，didn’t 站在动词原形前，其他部分不要变。
　　一般疑问句也好变，did放在句子前，主语、动词原形、其他部分依次站。
　　特殊疑问句也简单，疑问词加一般疑问句记心间。
　　最后一条请注意，动词过去式要牢记。
Ⅱ. 行为动词的一般过去式变化规则
行为动词的过去式有规则变化和不规则变化两种。规则动词过去式的构成有四条规则：
　　①一般在动词原形末尾直接加上-ed。如：look-looked。
　　②以不发音的字母e结尾的动词，去e再加-ed。如：live-lived。
　　③末尾只有一个辅音字母的重读闭音节，先双写这个辅音字母，再加-ed。如：stop-stopped。
④末尾是辅音字母+y结尾的动词，先变y为i，然后再加-ed。如：study-studied。
(2)不规则动词的过去式需特殊记忆。如：am(is)-was, are-were, go-went, come-came, take-took, have (has)-had等。

-ed结尾的动词过去式, 词尾ed有三种读音?[t] [d] [id]。
