过去完成时的标志词是什么?
过去完成时的标志词是：
1、时态结构形式：had+done（过去分词）。
2、时间上的表达：比如说since，before，after，when，as soon as，till，by等表示在这个行为发生前就已经过去的时间。
现在完成时简介：
现在完成时是过去的动作或状态持续到现在并且已经完成，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。
