这个就在一般过去时或者在虚拟语气中 用 如果作为过去分词的话 用处就更多了
发生在过去的事情 形式用动词+ed
不规则动词自己背表
过去式是指动词的过去式，比如do的过去式是did
而过去时是指句子的时态是过去，比如，I ate potatoes last night.
过去式是指动词的过去试。意为过去发生的动作，到现在已经停止这个动作。
动词过去式，一般直接加ed, 当然，也有例外的要特别记，例如take-took, bring-brought, buy-bought等等。
系动词的也是特殊的，需要记。如：am-was, is-was, are-were.....
还有其他的，找语法书认真看看
after went back to the classroom
简单来说就是以重读闭音节结尾的双写在加ed
重读闭音节：在单词后三位中,第一个为子音（除a,e,i,o,u外的字母）,第二个为母音（a,e,i,o,u）,第三个为子音,双写最后一个子音字母,再加ed
例如：sped begged fretted dragged dropped planned dotted dripped
规则动词的过去式词尾变化有几种：1．一般情况下加ed，如watched, planted, watered, pulled, climbed, picked。2．以不发音字母e结尾的加d，如liked, moved, tasted。3．以子音字母加y结尾的变y为i再加ed，如study——studied。4．以1个母音字母加1个子音字母结尾的重读闭音节，双写最后一个子音字母再加ed，如s——sped。词尾读音有3种：a．在浊子音和母音后读[d]，如lived, watered, listened, played。b．在清子音后读[t]，如liked, helped, watched。c．在[t],[d]音后读[Id]，如planted, wanted, handed(上交)。
动词原形变成现在进行式，结构为：am/is/are+动词的ing形式。am/is/are取决于主语的人称和数的变化（我用am，你用are，is就跟他她它，我们你们和他们一律全用are，are，are），动词的ing形式，则遵循这样一个法则：1.直接在动词末尾加上ing，如：doing,playing，seeing，working2.不发音e结尾的，去e加上ing。如：came-caming,make-making,dance-dancing等3.以重读闭音节结尾，并且只有一个子音字母的，双写子音字母在加ing如：begin-beginning,run-running,sit-sitting,shop-shopping等。
