一般过去时的用法和结构一般过去时的用法及结构一般过去时用于表示过去某个时间发生的动作或存在的状态，也可以表示过去经常或反复发生的动作。
通常与表示过去的时间状语一起使用，例如yesterday，last week，last night，in 2003，two days ago等。
例如，昨天我六点半起床了。
XXX.一般过去时的基本结构为：肯定句“主语+动词过去式+其他”或者“主语+was/were+其他”，否定句“主语+didn’t+动词原形+其他”或者“主语+XXX其他”，一般疑问句“Did+主语+动词原形+其他？”肯定回答为“Yes，主语+did”，否定回答为“No，主语+didn’t”或者“Was/Were+主语+其他？”肯定回答为“Yes，主语+was/were”，否定回答为“No，主语+XXX’t”。

上星期五老XXX不高兴。

为了帮助记忆实义动词一般过去时的用法和结构，我们可以使用以下歌诀：“动词一般过去时，表示过去发生事。
谓语动词过去式，过去时间作标志。
否定形式很简单，主语之后加didn't。
谓语动词要还原。
疑问构成有规则，主语前面加did。
”过去式的构成有两种方式：be动词和实义动词。
系动词be的过去式有两种形式：was和were。
其中，was是am和is的过去式，were是are的过去式。
实义动词过去式的构成有以下几种规则：1.一般在动词末尾加-ed，例如walk→walked，play→played；2.以不发音e结尾的动词末尾只加-d，例如love→loved，decide→decided；3.以“辅音字母＋y”结尾的动词，先将y变为i，再加-ed，例如study→studied，carry→carried；4.末尾只有一个辅音字母的重读闭音节，先双写该辅音字母，再加-ed，→ped，plan→planned。
口诀：“过去式构成有规律，一般词尾加-ed。
如果词尾有个e（不发音的），只需直接加上-d。
‘辅音字母＋y’在词尾，变y为i加-ed。
‘一辅重闭’作尾巴，双写之后加-ed。
