havebeendone是什么时态(hadbeendone什么时态)

have been done是现在完成时的被动结构。其被动语态完整结构：肯定式为“have/has+been+done”；否定式为“have/has+not+been+done”。现在完成时是表示过去的动作或状态持续到现在并且已经完成。

现在完成时是过去的动作或状态持续到现在，对现在造成的影响，可能持续发生下去。在英语时态中，“时”指动作发生的时间，“态”指动作的样子和状态。完成时态的构成分为两部分：一是助动词，二是实义动词的过去分词“-ed”。具体来说，用助动词have/has表示“时”，以表明动作发生的时间是在过去、现在还是将来；用过去分词来表示动作的“态”，以表明该动作已经完成，而且对现在有一定的影响。

现在完成时的应用

1、过去发生的动作对现在造成的影响。

2、过去的动作或状态持续到现在并且已经完成或可能持续下去。

3、现在完成时表示将来。
