【什么是过去式】在英语语法中，“过去式”是一个非常基础且重要的概念，用于描述发生在过去某一时间的动作或状态。掌握过去式的用法，有助于我们更准确地表达时间关系和事件的先后顺序。
过去式主要用来表示在过去某个时间点已经发生的事情。它通常通过动词的变化来体现，比如“go”变为“went”，“eat”变为“ate”。不同的动词有不同的过去式形式，有些是规则变化，有些则是不规则变化。
过去式是英语语法中的一种时态，用于描述在过去某一时间发生的动作或状态。它是英语中最常用的时态之一，广泛应用于日常交流和书面表达中。根据动词的规则与否，过去式可以分为规则动词和不规则动词两种类型。了解并正确使用过去式，对于提高英语表达能力至关重要。
