　　Worriedaboutthejourney,Iwasunsettledforthefirstfewdays.

　　Exhausted,Islidintothebedandfellfastasleep.

　　过去分词作状语：过去分词作状语时，说明动作发生的背景或情况，其等同于一个状语从句。vt过去分词作状语时与主句主语构成被动关系，表示被动和完成，vi过去分词表示状态或动作的完成。

　　Heated,waterchangesintosteam.

　　Theprofessorcamein,followedbyagroupofyoungpeople.

　　1作原因状语，等于as/since/because引导从句

　　Movedbywhatshesaid,wecouldn’thelpcrying.=Aswearemovedbywhatshesaid…

　　2作时间状语，等于when引导时间从句，如果分词表示的动作与谓语的动作同时发生，可在分词前加when/while/until等使时间意义更明确。

　　Whenheated,watercanbechangedintosteam.

　　Seenfromthehill,theparklooksverybeautiful.=Whentheparkisseenfromthehill…

　　3作条件状语等于if/whether引导从句

　　Givenmoreattention,thecabbagescouldhavegrownbetter.=Iftheyhavebeengivenmoreattention….

　　4作方式或伴随状语

　　Theactresscamein,followedbyherfans.

　　Shesatbythewindow,lostinthought.

　　5作让步状语

　　Muchtired,hestillkeptonworking.=Althoughhewastired,he….

　　6独立主格结构：当分词的逻辑主语不是主句主语时，分词可以有自己独立的逻辑主语，这种结构称为独立主格结构。常用来表示伴随情况。

　　Theboyrushedintotheclassroom,hisfacecoveredwithsweat.

　　Allthingsconsidered,yourarticleisofgreatvaluethanhers.

　　Rewritewithproperconjunctions

　　Example:Unitedwestand,pidedwefall.

　　Ifweareunited,wewillstand,butifwearepided,wewillfall.

　　现在分词与过去分词作状语

　　现在分词作状语时，与其逻辑主语之间是主动关系，;而过去分词与其逻辑主语之间则表示被动关系。

　　Seeingthesepictures,Icouldn’thelpthinkingofthosedayswhenIwasinBeijing.Seenfromthetopofathirty-storeyedbuilding,Beijinglooksmoremagnificent.see

　　选择现在分词还是过去分词，关键看主句的主语。如分词的动作是主句的主语发出，分词就选用现在分词，反之就用过去分词。例如：

　　Usedforalongtime,thebooklooksold.

　　由于用了很长时间，这本书看上去很旧。

　　Usingthebook,Ifindituseful.

　　在使用的过程中，我发现这本书很有用

　　注意:1.系表示主语所处的状态

　　_____inthought,healmostranintothecarinfrontofhim.lose

　　______inwhite,shelooksmorebeautiful.dress

　　belostin

　　bedressedin

　　beinterestedin

　　bedevotedto

　　besupposedto?becaughtintherain

　　beseatedin

　　bepreparedfor

　　bedeterminedto

　　2.不与主语保持一致的固定结构

　　generallyspeaking一般说来

　　strictly/franklyspeaking严格地说/坦白地说

　　judgingfrom从…判断

　　allthingsconsidered从整体来看

　　takingallthingsintoconsideration全面看来

　　例如：Judgingfromhisface,hemustbeill.从他的脸色看，他一定是病了。

　　Generallyspeaking,dogscanrunfasterthanpigs.

　　总的来说，狗比猪跑得快。speaking不是dogs的动作
