初一英语过去式

一、一般过去时的概念： 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, in 1990, two days ago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①I saw him in the street yesterday. 昨天我在街上看见他了。 ②Li Mei always went to school on foot last year. 去年李梅总是步行上学。 二、一般过去时的构成： 1. be动词的一般过去时的构成： 第一人称单数和第三人称单数用was, 其余人称用were 例如：①I was ten years old at that time. ②There were many people standing in front of the door. 2. 实义动词的一般过去时的构成： (1) 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 work---worked jump---jumped  stay---stayed ②以不发音的字母e结尾的动词，直接加d。 如：live---lived  close---closed  dance---danced 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  shop---shopped  prefer---preferred ④末尾是辅音字母加y结尾的动词，先变y为i，然后再加ed。 如study---studied try---tried (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 三、一般过去时的几种句型： (1) be动词的一般过去时的句型： ①肯定句结构为：主语+was / were+其它。 如：I was at home yesterday.
