1.以上句子中，句1中为过去分词短语作状语，通常放于 。2.句2和句5中为过去分词作 。3.句4中为单个的过去分词作定语，常常放于被修饰名词的 ；句3中为过去分词短语作定语，常常放于被修饰名词的 。4.句6中为过去分词短语作 。
一、过去分词作定语1.意义：及物动词的过去分词作定语往往表示被动和完成；不及物动词的过去分词作定语不表示被动，只表示完成。(1)表示被动和完成a plluted river一条被污染的河流the watered flwers浇过水的花(2)只表示完成，不表示被动fallen leaves落叶the risen sun升起的太阳
2.位置：单个的过去分词作定语时，通常放在被修饰词的前面；过去分词短语作定语时，通常放在被修饰词的后面，其作用相当于一个定语从句。The student dressed in white is my daughter.＝The student wh is dressed in white is my daughter.穿白色衣服的那个学生是我女儿。注意：过去分词作定语和现在分词作定语的区别：(1)语态不同：现在分词表示主动；过去分词表示被动。The questin discussed was very imprtant.讨论过的那个问题很重要。The huse standing at the crner f the street was built in 2016.矗立在街道角落的那所房子是2016年建的。
(2)时间关系上不同：现在分词表示动作正在进行；过去分词表示动作已经完成。
3.过去分词(dne)、现在分词的被动语态(being dne)与动词不定式的被动语态(t be dne)作定语的区别
The building built last year is ur classrm building.去年建造的楼是我们的教学楼。The building being built nw is ur classrm building.现在正在建造的楼是我们的教学楼。The building t be built next mnth is ur classrm building.下个月将要建造的楼是我们的教学楼。
二、过去分词作表语1.意义：用在系动词后面，构成系表结构，表示主语所处的状态。She lked disappinted.她看上去很失望。We were encuraged at the news.听到这个消息我们很受鼓舞。2.过去分词作表语表示主语所处的状态。这一结构从形式上与被动语态相同，但被动语态强调主语所承受的动作。试比较：
3.感觉类及物动词的现在分词与过去分词作表语的区别。英语中有很多与感觉有关的及物动词，其现在分词表示主动意义，即“令人有某种感觉的”，多用来修饰物；其过去分词含有被动意义，即“人被引起某种感觉的”，多用来指人、人的声音、笑容或表情等。常用的这类词有：
We were surprised at what he said at the meeting.我们对他在会上讲的话很是惊讶。His wrds were discuraging，which made many peple discuraged.他的话令人泄气，使得很多人灰心丧气。
三、过去分词作状语1.意义：过去分词作状语，修饰谓语动词，进一步说明谓语动词的动作和状态，其逻辑主语通常就是句子的主语，且主语是过去分词动作的承受者。过去分词作状语时，可单独使用，也可以在其前面加上适当的连词，可表示时间、原因、条件、伴随、方式等。Greatly interested，I asked hw he played these new wrks.因为非常感兴趣，我问他是如何演奏这些新作的。Given gd health，I hpe t finish the wrk this year.如果身体好，我希望今年完成这项工作。The scientist Tu Yuyu came in，fllwed by her assistant.科学家屠呦呦进来了，后面跟着她的助手。
When seen frm the tp f the hill，the park lks mre beautiful.从山顶往下看时，这座公园看起来更加漂亮。2.功能：过去分词作状语，在意义上相当于一个状语从句。它可以表示时间、原因、条件、让步、方式或伴随等。(1)表示时间，可转换为when，while或after等引导的时间状语从句。Accepted by the Party，he decided t devte his life t the cause f the Party.＝When he was accepted by the Party，he decided t devte his life t the cause f the Party.入党以后，他决定献身于党的事业。
(2)表示原因，可转换为as，since或because等引导的原因状语从句。Deeply mved by the stry，the excited peple stpped quarrelling with each ther.＝Because they were deeply mved by the stry，the excited peple stpped quarrelling with each ther.激动的人们被那个故事深深地打动了，停止了争吵。(3)表示条件，可转换为if，nce或unless等引导的条件状语从句。If heated，water can be turned int vapur.＝If it is heated，water can be turned int vapur.水如果被加热，会变成水蒸气。
(4)表示让步，可转换为althugh，thugh或even if等引导的让步状语从句。Exhausted by the running，they went n running after the rbber.＝Althugh they were exhausted by the running，they went n running after the rbber.尽管已经跑得筋疲力尽，他们还是继续追赶那个抢匪。
(5)表示方式或伴随情况。作方式状语，如有连词as if，可转换为as if引导的方式状语从句；若无连词，则转换为并列结构。作伴随状语，一般转换为并列结构。The ld man went int the rm，supprted by his wife.＝The ld man was supprted by his wife and went int the rm.那个老人在妻子的搀扶下走进了房间。
3.连词＋过去分词：分词作时间、条件或让步状语时，为了明确其意义有时可在分词前加上when，while，if，nce，unless，althugh等连词。相当于状语从句的省略。If merely drawn n yur imaginatin，the reprt will nt be cnvincing.假若仅靠你的想象去写，报告是不会有说服力的。注意：有些过去分词来源于系表结构，作状语时不表示被动而表示主动。这样的过去分词及短语常见的有：lst(迷路)，seated(坐)，hidden(躲)，statined(驻扎)，lst/absrbed in(沉溺于)，brn(出身于)，dressed in(穿着)，tired f(厌烦)等。Lst/Absrbed in deep thught，he didn’t hear the sund.因为陷入沉思之中，所以他没听到那个声音。
四、过去分词作宾语补足语1.意义：过去分词作宾补，说明宾语的状态或性质，与宾语一起构成复合宾语，它前面的宾语就是其逻辑主语。作宾补的多是及物动词。(1)过去分词作宾补表示被动关系，其动作先于谓语动词所表示的动作。(2)过去分词作宾补时，过去分词所表示的动作一定和宾语有逻辑上的动宾关系。
2.能够接过去分词作宾补的动词有以下三类：(1)表示感觉或心理状态的动词。如：see，watch，bserve，find，hear，feel，ntice，think等。I heard the sng sung in English.我听到有人用英语唱过这首歌。He fund his purse lst.他发现他的钱包丢了。(2)表示“致使”意义的动词。如：have，make，get，keep，leave等。I’ll have my hair cut tmrrw.明天我要理发。
He gt his tth pulled ut yesterday.他昨天把牙拔了。Dn’t leave thse things undne.务必把那些事情做完。(3)表示“希望”“要求”意义的动词。如：like，rder，want，wish，expect等，其结构为“vt.＋宾语＋(t be) p.p.”。I wuld like this matter (t be) settled at nce.我希望此事立刻得到解决。I wish my hmewrk (t be) finished befre five ’clck.我希望在5点前完成我的作业。
3.过去分词作宾补时，要注意以下几种情况：(1)使役动词have接过去分词作宾补有两种情况：①过去分词所表示的动作由他人完成。He had his mney stlen.他的钱被偷了。(被别人偷去了)②过去分词所表示的动作由句中的主语所经历。He had his leg brken.他的腿断了。(自己的经历)
(2)过去分词在原句中作宾补时，如果原句变为被动语态，那么过去分词就在新句中作主补了。Almst n student is seen punished in this schl.在这所学校，几乎见不到学生被惩罚。
