分词有时态变化吗？
分词结构分为现在分词和过去分词两种：现在分词表示“主动和进行”，过去分词则表示“被动和完成”，若为及物动词，该动作与句中的逻辑主语为被动关系;若为不及物动词，该动作则只表示完成。
1、现在分词的时态：一般时态（doing）表示正在进行或与谓语动词同时发生的动作；完成时态（have done）表示先于谓语动词的动作。例如：
Glancing at her scornfully，he told her that the dress was sold.他轻整地看了看她，说连衣裙已经被卖出去了。Following this route，you can easily find every place you want to go to on our campus.沿着这条道，便可以很容易地在校园里找到你想去的任何地方。
2、现在分词的被动语态：一般式（being done），完成式（having been done）。例如：
患病的问题是非常重要的。The problerm being diseussed is very important.正在讨论的问题很重要。Having been informed，the thicf ran away before the policc arrived.小偷得到了消息，在警察到来之前便逃走了。
3、过去分词只有一种形式，表示在谓语动词之前的动作。及物动词的过去分词与句子的逻辑主语有被动关系；不及物动词的过去分词与逻辑主语有主动关系。例如：
Praised by the neighbours，he became the pride of his parents.受到邻居们的表扬，他成了父母的骄傲。The retired worker usually waters his garden every day except on rainy days.除了雨天，这位退休工人每天都在花园里浇水。
4、分词的否定形式是在分词前加上否定词not，never等。例如：
Not wanting to frighten the poor man，she quickly hid in the small store-room.不想吓着那个可怜的人，她迅速躲到了小储藏室里。Never invited to his party，she got angry with him.从未被邀请去参加他的聚会，她很生气。
