have done是什么时态？ 现在完成时态，表示过去发生的动作对现在造成的影响或结果。

have done时态详解

现在完成时

现在完成时由助动词have/has加上动词的过去分词构成，强调动作发生在过去，但对现在有影响。例如：“She has been sweeping the street all day. She is too tired.”（她一整天都在扫大街，她太累了。）时间状语往往可以省略，因为动作对现在的影响显而易见。 2

过去完成时

过去完成时则以过去某个时间为标准，表示在此以前发生的动作或行为，即“过去的过去”。其基本结构是had done，常用于before, by the end of last year等时间状语前。例如：“By the end of last year, he had learned five foreign languages.”（到去年年底，他已经学了五种外语。） 3

现在完成进行时

现在完成进行时表示从过去某时开始一直延续到现在还在进行，或可能还要继续下去的动作，强调动作的持续性和不间断性。结构为have/has been doing。例如：“I have been studying English for ten years.”（我已经学了十年英语了。） 4
