为了便于记忆行为动词(实义动词)的一般过去时用法及结构,我们可用以下歌诀来帮助记忆: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didn’t添。
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
be动词和实义动词过去式的构成: ⑴ 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。
⑵ 规则动词过去式的构成:
①一般在动词末尾加—ed。 【举例】walk→walked play→played
②以不发音e结尾的动词末尾只加—d 。【举例】love→loved decide→decided
③结尾是“辅音字母+y ”的动词。先将y 变为i,再加—ed 。 【举例】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 。 【举例】stop→stopped plan→planned
规则动词的过去式构成方法可用以下口诀来记忆:
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 。
