1．过去分词可放在连系动词be, get, feel, remain, seem, lk, becme等之后作表语，表示主语所处的状态常见的这种过去分词有:be interested, be surprised, be astnished, be amazed, be mved, be exhausted, be wrried, be devted, be pleased, be inspired, be encuraged, be excited, be delighted, be satisfied, be scared, be inspired, be encuraged, be excited…Tm was astnished t see a snake mving acrss the flr．汤姆很惊讶地看到一条蛇正爬过地板。Finally the baby felt tired f playing with thse tys．终于婴儿厌倦了玩那些玩具。
2．过去分词作表语时与被动语态的区别过去分词作表语时，强调主语所处的状态；而动词的被动语态表示主语是动作的承受者，强调动作。The library is nw clsed．(状态)图书馆现在关闭了。The cup was brken by my little sister yesterday．(动作)昨天我妹妹把杯子打碎了。
3．感觉类及物动词的现在分词与过去分词作表语的区别过去分词作表语多表示人自身的感受或事物自身的状态，常译作“感到……的”；现在分词多表示事物具有的特性，常译作“令人……的”。We were amazed 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。
(2018•全国卷Ⅲ)I quickly lwer myself，ducking my head t avid lking directly int his eyes s he desn’t feel ____________(challenge)．解析：考查词性转换之动词变为形容词。连系动词feel后要接形容词作表语。challenged adj．受到挑战的；challenging adj．困难的，富有挑战性的。 由语境可知，填challenged。答案：challengedI‘m __________（interest）in reading nvels, written (非限制性定语）by Jin Yng. 我对金庸的小说很感兴趣.答案：interested
过去分词表示完成或被动，作状语时，表示动作发生的背景或者情况，在意义上相当于一个状语从句，其省略的主语（逻辑主语）是主句的主语，且与主语之间存在被动关系。过去分词作状语可以表示时间、条件、方式、原因、让步等。过去分词的否定式是将nt放在其前面。
1．过去分词作时间状语过去分词作时间状语时，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。Lked at frm a distance, the painting seems much mre beautiful．→When it is lked at frm a distance, the painting seems much mre beautiful．当从远处看时，这幅画似乎更美了。
2．过去分词作原因状语过去分词作原因状语时，可转换为由since, because或as引导的原因状语从句，这类状语多放在句子的前半部分。Wrried abut the exam, I was unsettled in these days．→Because I was wrried abut the exam, I was unsettled in these days．由于担心考试，我这几天感到不安。
3．过去分词作条件状语过去分词作条件状语时，可转换为if, nce或unless等引导的条件状语从句。Grwn in rich sil, these seeds can grw fast．→If they are grwn in rich sil, these seeds can grw fast．如果种在肥沃的土壤里，这些种子能长得很快。Given a few minutes, I’ll finish the reprt．→If I am given a few minutes, I’ll finish the reprt．再给我几分钟的时间，我就会完成这个报告。
4．过去分词作让步状语过去分词作让步状语时，相当于一个以thugh/althugh引导的让步状语从句。Encuraged by his parents, he still has n cnfidence in vercming the difficulties．→Thugh he was encuraged by his parents, he still has n cnfidence in vercming the difficulties．尽管受到了父母的鼓励，他仍然没有信心克服困难。Invited by him, I wn’t take part in the party．→Thugh I was invited by him, I wn’t take part in the party．即使被他邀请，我也不会参加聚会。
5．过去分词作方式/伴随状语过去分词作方式或伴随状语时，通常不能转换为状语从句，但可用并列分句代替。The patient gt ff the bed, supprted by the nurse．→The patient gt ff the bed, and he was supprted by the nurse．那个病人在护士的搀扶下下了床。She accepted the gift, deeply mved．→She accepted the gift, and she was deeply mved．她接受了礼物，深深地被感动了。
温馨提示：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：lst(迷路); seated(坐); hidden(躲); lst/absrbed in(沉溺于); dressed in(穿着); tired f(厌烦)。Lst in thught, he didn’t hear the bell．由于陷入沉思之中，他没有听到铃声。
(2018•全国卷Ⅲ)Everyne was silent, ____________ (wait) t see wh wuld be called upn t read his r her paragraph alud．解析：考查非谓语动词作状语。主语Everyne与wait为主动关系，故用现在分词作状语，故填waiting。答案：waiting____________ (give) in rich sil, these seeds can grw fast.答案：Given
过去分词与现在分词作状语的区别
过去分词与句子的主语之间存在逻辑上的动宾关系，即表示被动；现在分词与句子的主语之间存在逻辑上的主谓关系，即表示主动。分词作状语记忆口诀分词作状语，主语是问题。前后两动作，共用一主语。主语找出后，再来判关系。主动用­ing，被动用­ed。
