现在进行时被动语态,一般过去时被动语态,一般现在时被动语态

现在进行时被动语态am / is / are + being + 及物动词的过去分词Uncle Wang is mending my bike now。→My bike is being repaired by Tom now。They are planting trees over there。→Trees are being planted over there by them。个人认为就是正在进行中的事情主语为事情的承受者一般过去时被动语态was / were + 及物动词的过去分词A new shop was built last year。Dinosaur eggs were laid long long ago。发生在过去一般现在时被动语态is / am / are + 及物动词的过去分词Our classroom is cleaned everyday。I am asked to study hard。Knives are used for cutting things。现在发生的最平常的事情希望能帮上忙
