15、用关系时用过去分词过去分词。在独。在独立主格结构中，如果强调分词的时间发立主格结构中，如果强调分词的时间发生在主句动词时间之前，常用现在分词生在主句动词时间之前，常用现在分词完成时态表示。完成时态表示。如：如：Winter coming,its getting colder and colder.(winter和和come是逻辑主谓关系是逻辑主谓关系)More money given,we should have sent more employees to the mother company to get trained.(句中句中money与与give是动宾关是动宾关系，所以用过去分词系
