分词的用法注意：美联英语的小编老师给大家一起看看吧。。
1. 分词的两个结构
否定结构：not + 分词
not having known his address, i didn’t write to him.
复合结构（独立主格结构）有两种形式：
名词（代词主格）+分词（只作状语）
with+名词（代词宾格）+分词（作状语或定语）
the day’s work done, they went home. 他们做完的工作就回家了。
he sat there with his feet pointing to others. 他坐在那儿，把脚指向别人。
2. 现在分词的完成时态不能作表语、定语和宾补，只放在状语的位置上。现在分词一般时态的被动结构（being + v.-ed）表示“正在被”之意，而在动名词中只表示被动。
having answered the letter, he stood up and talked to me.（时间状语）
being cheated made him sad. （被骗这件事，不一定是正在受骗）
the meeting being held now is of great importance. 现在正在开的会很重要。
3. 一些只用现在分词形式的固定结构：generally/ seriously speaking，judging from (by)…，但to tell the truth, to be sure, to be exact 要用不定式。
