◆语法精析
过去分词作状语过去分词(短语)作状语，表示被动的或完成的动作，这时句子的主语和过去分词之间为逻辑上的被动关系。Written in a hurry，this article was not so good.因为写得匆忙，这篇文章不是很好。本句中的written即为过去分词作状语，表示这篇文章是被写的，而且已经被写完。过去分词通常在句中作时间状语、原因状语、条件状语、让步状语、方式状语和伴随状语等。
1.过去分词作时间状语，在句中相当于一个时间状语从句。Asked about his address (＝When he was asked about his address)，the boy didn’t respond.问及他的地址时，小男孩没有作答。2.过去分词作原因状语，在句中相当于一个原因状语从句。Annoyed at the decision(＝As he was annoyed at the decision)，he refused to attend the meeting.由于对这个决定很生气，他拒绝参加会议。
3.过去分词作条件状语，在句中相当于一个条件状语从句。Given more time (＝If they were given more time)，the trees could grow taller.如果再多给一点时间，这些树会长得更高。Heated to a high temperature (＝If it is heated to a high temperature)，water will change into vapor.如果加热到高温，水就能变成蒸汽。4.过去分词作让步状语，在句中相当于一个让步状语从句。Though warned of the storm (＝Though they had been warned of the storm)，the farmers were still working in the fields.尽管被警告过有暴风雨，农民们仍然在田地里劳作。
5.过去分词作方式、伴随状语。Followed by a group of students，the teacher entered the classroom.＝The teacher entered the classroom and he was followed by a group of students.老师走进教室，后面跟着一群学生。注意：过去分词(短语)作状语时，前面有时可以加上when，if，while，though，even if，until，unless等连词，这种结构可以看作是一种省略的状语从句(省略部分多为“主语＋be的多种形式”)。需要注意的是，省略的主语必须和主句的主语相同或主语为it。
Even if invited (＝Even if I’m invited)，I won’t take part in the party.即使受到邀请，我也不会参加那个聚会的。注意：现在分词也可以作状语，与过去分词作状语的最主要区别在于：两者与所修饰的主句的主语的逻辑关系的区别。
1.现在分词作状语时，现在分词所表示的动作与句子主语之间构成逻辑上的主动关系。The girl went out，shutting the door behind her.女孩出去后将门随手关上。 Not knowing what to do，she went to her parents for help.由于不知如何办是好，她去找父母帮忙。2.过去分词作状语时，过去分词所表示的动作与句子主语之间构成逻辑上的被动关系。Given more encouragement，the girl could have behaved better.如果多给这个女孩一些鼓励，她本来会表现得更好。
Written by a famous writer，the novel sells well.因为这部小说是一位著名作家写的，所以很畅销。3.部分过去分词来源于系表结构，作状语时不表示“被动关系”，其前不用being。这样的过去分词及短语常见的有：lost in(陷入某种状态)、seated(坐着的)、hidden(躲着)、lost/absorbed(沉溺于)、dressed in(穿着)、tired of(厌烦了)等。 Lost/Absorbed in deep thought，she didn’t hear the sound.由于陷入沉思，所以她没有听到那个声音。Born in this beautiful town，the girl hates to leave it.出生于这个美丽的小镇，女孩不愿离开它。
