be (am/is/are) + 动词-ing
1.表示现在正在进行或发生的动作。
2.表示现阶段或当前一段时间之内 正在进行的动作。
nw、lk、listen、these days等
动词-ing形式的构成
a.一般情况下，在动词词尾后加-ing。如：g → ging。b.以不发音的e结尾的动词，去掉e加-ing。如：have → having。c.以重读闭音节结尾的动词，末尾只有一个辅音字母，双写这个辅音字母，再加-ing。如：run → running。
have/has + 过去分词
1. 表示过去发生或已经完成的动作对现在造成的影响或结果。
2. 从过去某一时间开始并一直持续到现在且还有可能持续下去的动作。
already、yet、ever、never、fr +时间段、since +时间点、s far、in the 等
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。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 putAAB型 beat beat beatenABA型 becme became becmeABB型 get gt gt/gttenABC型 begin began begun

主动语态和被动语态的区别
主动语态表示主语是动作的执行者。被动语态表示主语是动作的承受者，即行为动作的对象。I cleaned my rm. → My rm was cleaned by me.I saw him crss the rad and enter the shp. → He was seen t crss the rad and enter the shp.
在含有使役动词 (如：make) 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。
被动语态的基本结构：助动词be + 及物动词的过去分词一般现在时的被动语态：am/is/are + 过去分词一般过去时的被动语态：was/were + 过去分词一般将来时的被动语态：will be/is ging t be + 过去分词含情态动词的被动语态：情态动词 + be + 过去分词
