英语语法基本知识时态.docx

1、英语语法基本知识时态英语的时态问题英语的时态可以分为： “时”(time) 和 “体”(aspect)（又称为态）。时是指动作发生的时间，体是指动作发生时的状态。时间与体就象是坐标里的横轴和纵轴，它们的结合交织出了瞬息万变的时空，也构成了英语动词的时态问题。时间分为：过去，现在，将来，过去将来体分为：一般（在某个时间点），进行（延续某个时间段），完成（完成某个时间段）完成进行 （延续某个完成的时间段）如此以来，英语中就有16种时态变化，现在就用动词为write例，看看它们的形式。注意：里面的斜体字部分，由于时态过于复杂，几乎没有人真正去应用它们，可以忽略不记。时间体现在过去将来过去将来一般Wr
