have/has + 过去分词
1. 过去发生或已经完成的动作对现在造成影响或结果
2. 从过去某一时间开始一直延续到现在并还可能继续延续下去的动作
already, yet, ever, never, just, befre, nce, twice, recently, s far, fr +时间段，since +时间点/从句。
一般情况下，在动词后加-ed。如: wrk → wrked。在以e结尾的动词后只加 -d。如: clse → clsed。在以辅音字母加y结尾的动词，应将y改为i再加ed。如: study → studied。以重读闭音节结尾的动词，要双写末尾的辅音字母再加-ed。如: stp → stpped。不规则动词的过去分词: AAA型 put put put AAB型 beat beat beaten ABA型 becme became becme ABB型 get gt gt/gtten ABC型 begin began begun

在含有使役动词 (make, let等) 或感官动词 (see, watch, ntice, hear等) 的主动语态的句子中，这些词后常跟省略t的动词不定式，但是改为被动语态时则要把省去的t还原。
被动语态的构成：be + 过去分词一般现在时被动语态：am/is/are + 过去分词一般过去时被动语态：was/ were + 过去分词一般将来时被动语态：will be/ is ging t be + 过去分词情态动词的被动语态：can/culd/may/might/shuld/must + be + 过去分词
