1、精选优质文档-倾情为你奉上初中英语各种时态的讲解及练习一 关于时态。 时态其实是指的两个概念：其一是指时间，其二是指：在不同的时间条件下动词的形式。时间上英语主要分为三段：过去时间，现在时间和将来时间。动词的形式有五种,情态动词除外。（原型do、三单does、现在分词doing、过去式did、过去分词done）。其实时态主要就是在考察动词。因此同学们一定要有这个意识：只要一说起时态我们就要去关注谓语动词怎么变化（用什么样的形式）二、初中阶段主要要掌握以下8种时态： 1. 现在类的时态1.一般现在时态:2.现在进行时态3.现在完成时态 4.现在完成进行时态（了解） 2. 过去类的时态: 1.一般
