formusedasadverbial状语动词-ing形式是非谓语动词的一种，兼有动词和形容词的特征，在句中可作表语，定语，宾语补足语和状语，一般表示进行或主动的意思。动词-ing形式用作状语时，其逻辑主语必须与句子的主语一致，动词-ing形式所表示的动作和句子的主语是主动关系。动词-ing形式在句中可以作时间、原因、条件、让步、方式、伴随和结果状语。动词-ing形式作状语1.作时间状语

egSeeing

thepolice,hemadearunfortheexit.

一看到警察，他就朝出口奔去。分析：see的动作是由其逻辑主语“he”发出，与句子的主语he一致，且构成主动关系，所以用动词-ing形式。将下面的时间状语从句改写成简单句。Whenhewalkedoutoftheroom,hesawadog.Walkingoutoftheroom,hesawadog.1.现在分词作时间状语（when,while,until）当她在公园里散步时，她看到了她的一个老朋友。When/while(shewas)walkinginthepark,shesawanoldfriend.＝Walkinginthepark,shesawanoldfriend.e.g.Being

ill,hedidn’tgotoschoolyesterday.

因为生病了，他昨天没有上学。分析:Heisill是Hedidn’tgotoschool的原因。be的逻辑主语和句子主语是一致,主动关系。Notknowingtheway,hegotlost.翻译句子：由于不认路，他迷路了。

Ashe____________________,hegotlost.didn’tknowtheway动词-ing形式的否定式是在其前面加not。2.作原因状语2.现在分词作原因状语（since,because或as）Ashewasill，hecouldn'tgotoschool.＝Beingill，hecouldn'tgotoschool.Becausehewaspoor,hecouldn’taffordaTVset.=Beingpoor,hecouldn’taffordaTVset.e.g.Turning

totheleft,youwillseeaschool.

向左转你就会看到一所学校。Ifwe___________,wewillsucceed.翻译句子：努力学习,我们就会成功。Studyinghard,wewillsucceed.studyhard3.作条件状语3.现在分词作条件状语(if,once或unless)

Ifyouworkhard，you'llmakegreatprogress.＝Workinghard，you'llmakegreatprogress.Ifyouuseyourhead,you’llfindagoodway.=Usingyourhead,you’llfindagoodway.e.g.Granting

thistobetrue,wecannotexplainit.

用动词-ing形式作状语的结构翻译下列句子。

while,

though,

unless,if,even

if等)特别提醒:1.Don’t

talk

dinner.吃饭时不要说话。2.Once
