过去分词短语作状语，就像给句子加一个“背景说明”，可以表示“什么时候”“虽然怎样”“如果怎样”“因为什么”“怎么做到的”或“结果怎样”，相当于一个简单的从句。

。(1)作时间状语相当于时间状语从句。可在过去分词前加上连词when,while,until等，使其时间意义更明确。

Whenaskedtoanswerthequestioninclass,Lilyraisedherhandconfidently.=When(shewas)askedtoanswerthequestioninclass,Lilyraisedherhandconfidently.

BecauseAlicewasabsorbedinreading,shedidn'thearthebellring.Alicewasabsorbedinreading,soshedidn'thearthebellring.

Absorbedinreading,shedidn'thearthebellring.

过去分词作状语(3)作条件状语相当于条件状语从句。可加连词if,unless等转换成条件状语从句。Ifitiskeptinadryplace,thebookwillstaynewforalongtime.Keptinadryplace,thebookwillstaynewforalongtime.过去分词作状语过去分词作状语(4)作让步状语相当于让步状语从句。有时可加although,though,evenif,eventhough,whether...or等连词转换成让步状语从句。Althoughshewaslaughedatbyclassmates,shekeptpracticing.Laughedatbyclassmates,shekeptpracticing.(5)作方式、伴随状语相当于and连接的并列句。

heteacherwalkedintotheclassroom,followedbytwostudents.过去分词作状语Part.2特殊情况特：有些过去分词(短语)因来源于系表结构，作状语时不强调被动而重在描述主语的状态。这样的过去分词(短语)常见的有lost(迷路)；seated(坐)；hidden(躲)；lost/absorbedin(沉溺于)；dressedin(穿着)；tiredof(厌烦)。

Lostinthought,hedidn'thearthebell.由于陷入沉思之中，他没有听到铃声。情况1英语中有些过去分词已经转化为介词或连词，它们已不具有一般过去分词的特点和用法。Providedthatoneisdiligentandpatient.onecanachievesomething一个人只要勤奋且有耐心，就能干成一番事业。Givenherinterestinchildren,teachingseemstherightjobforher考虑到她喜欢孩子，教学看来很适合她情况2Part.3Practice
