一． 一般过去时的基本用法
1． 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。
1. yesterday或以其构成的短语：yesterday morning(afternoon， evening)等；
2. 由“last+一时间名词”构成的短语:last night, last year (winter， month, week）等;
3. 由“时间段+ago”构成的短语：a moment ago, a short time ago， an hour ago等；
4。 其它：just now等
5。 由某些表示过去时态的从句等：when I was ten years old.
如:he was late yesterday。
I did my homework three hours ago.
I came home just now.

2. 表示过去习惯性、经常性的动作.常与often,always等连用。
如：He always carried a book.
二． 一般过去式的构成形式
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调到句首。
2．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 went home yesterday。
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：Jim went home yesterday。
Did Jim go home yesterday？
特殊疑问句：⑴疑问词+一般疑问句？如：Jim went home yesterday.
Did Jim go home yesterday?
What did Jim do yesterday?

三、规则动词的过去式

1.一般情况下,在动词原形后面加—ed。
look→looked   play→played   start→started   visit→visited

2。以不发音e结尾的动词，在词尾直接加—d。
live→lived   use→used

3.以“辅音字母+ y”结尾的动词，先将 y 改为i ，再加 –ed。
study→studied  try→tried   fly→flied

4.以重读闭音节(即辅音＋元音＋辅音）或r音节结尾，末尾只有一个辅音字母的动词，要先双写这个辅音字母后，再加 –ed。
stop→stopped　　plan→planned  prefer→preferred

5.不规则动词的过去式需特殊记忆。

附：一般过去时口诀：
动词一般过去时，表示过去发生的事；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。
否定句很简单，主语之后didn’t添；
疑问句也不难,did放在主语前； 不含be动词时
如果谓语之前有did，谓语动词需还原；
动词若是was,were,否定就把not添。 含be动时
疑问句也不难，要把was，were放在主语前。
