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”。
例如，我上周末打网球了。我的学校郊游棒极了。
这个女孩昨天下午没玩电子游戏。上星期五老XXX不高兴。
特殊疑问句的结构为：特殊疑问词+一般疑问句（顺序）？
例如，XXX上周末干什么了？他去看了他的祖父母。你昨天在哪儿？我在家里。
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。”
