1、Book5Unit3Grammar过去分词作状语课前回顾和预习：在Unit1和Unit2里，我们学习了过去分词作定语、表语、宾语补足语的用法，过去分词还可以作什么成分呢？【原文重现】课文回顾并判断V-ed形式在句子中充当的成分。1.Worriedaboutthejourney,Iwasunsettledforthefirstfewdays.(__状_语)2.Well-knownfortheirexpertise,hisparents’company,...inatimecapsule.(_状_语)3.Hitbyalackoffreshair,myheadached.(__状_语)4.Exha
2、usted,Islidintobedandfellfastasleep.(__状__语)5.Deeplytouched,Ithankedhimagainandagain.(__状__语)6.Caughtinaheavyrain,hewaslateforworkagain.(_状_语)【知识归纳】1.过去分词（短语）作状语表示(时间)完成和(语态)被动的意义。Written(write)inahurry,thisarticlewasterrible!2.过去分词（短语）作状语时，其逻辑主语是句子的主语。eg.Ifcaught,thethiefwillbepunishedbythepolice.
3、(caught的逻辑主语是thethief)练习：Offeredgreathelp,Icangetridofallthedifficulties.(offer的逻辑主语是I)3.过去分词（短语）作状语，可以表时间、原因、条件、让步、方式或伴随等情况,可转化为对应的状语从句。1）作时间状语，可转化为由连词“when,while,until”等引导的时间状语从句Seenfromthehill,theparklooksverybeautiful.=Whenitisseenfromthehill,theparklooksverybeautiful.2）作原因状语，可转化为由连词because等引导的

6、可放在主句前作句首状语,后面有逗号与主句隔开；也可放在主句后面,前面有逗号与主句隔开,位置较为灵活。Hestoodtheresilently,movedtotears.=Movedtotears,hestoodtheresilently.【注意】1.过去分词（短语）作状语时，分词的逻辑主语与句子的主语要一致。Theteachercuredmeofmybadbehavioranddeeplytouched,__I___thankedhimagainandagain.(he,him,I,me)2.有些过去分词已经形容词化，作状语时表示人的状态，常见的有:satisfied，surprised，i
