5、语的动作则与谓语的动作有时间间隔。例：Locking the door, she went out.Having lost his job, he began to interest himself in local voluntary work.延续性动词的现在分词一般式往往表示动作在发生过程中谓语动词动作发生，而当现在分词动作在谓语动作前发生且持续一段时间时，必须用现在分词的完成式。例：Having been his own boss for such a long time, he found it hard to accept orders from others.Searching
