一、过去分词作表语和状语时与动词-ing形式的比较1. 过去分词和动词-ing形式作表语时，过去分词与其逻辑主语之间是被动关系，而动词-ing形式则表示主动关系。如：We were amazed t find that n ne was hurt.我们很惊讶地发现竟没有人受伤。By the way, the machine is simply amazing.顺便提一句，这台机器简直太了不起了。D yu feel frightened when walking hme alne in the dark?你在黑夜单独走路回家会感到害怕吗？Walking hme alne in the dark can be frightening.在黑夜单独走路回家可能是很可怕的。
2. 过去分词和动词-ing形式作状语时，一般在句子中表示时间、原因或伴随状态等。过去分词与其逻辑主语之间是被动关系，往往含有完成义，而动词-ing形式则表示主动关系。如：Seen frm the hill, the city lks magnificent.从山上看时，这座城市非常美。Seeing the plice, he made a run fr the exit.一看到警察他就向出口奔去。.Influenced by his example, they perfrmed cuntless gd deeds.在他事迹的影响下，他们做了无数的好事。He sat at the table, reading a magazine.他坐在桌子旁看杂志。
二、过去分词作表语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，表示主语所处的情绪或状态。He seemed quite delighted at the news.听到那个消息他似乎很高兴。The dr remained lcked.门仍然锁着。
2. 过去分词作表语与被动语态的区别“be +过去分词”表示状态时，是系表结构，此时的过去分词通常已形容词化；表示动作时，是被动语态，且绝大多数被动结构中的动作执行者由介词by引出。The bk is well written.这本书写得很好。（系表结构，强调主语所处的状态）The bk was written by M Yan.这本书是莫言写的。（被动语态，强调主语所承受的动作）
3. 英语中有很多与感觉有关的使令动词，其现在分词表示主动意义，即“令人……的”，多用来修饰物；其过去分词表示被动意义，即“感到……的”，多用来修饰人、人的声音或表情等。常用的这类词有：amazing令人惊讶的 amazed惊讶的surprising令人吃惊的 surprised吃惊的exciting令人激动的 excited激动的astnishing令人惊讶的 astnished感到惊讶的 inspiring鼓舞人心的 inspired受鼓舞的disappinting令人失望的 disappinted感到失望的
encuraging令人鼓舞的 encuraged受鼓舞的interesting有趣的 interested感兴趣的frightening令人害怕的 frightened受惊的mving感人的 mved感动的pleasing令人高兴的 pleased高兴的shcking令人震惊的 shcked感到震惊的tiring令人疲惫的 tired疲惫的
wrrying令人担心的 wrried担心的satisfying令人满意的 satisfied感到满意的 puzzling令人迷惑的 puzzled困惑的
注意：有些使令动词，如dress，seat，absrb等，其过去分词无论作定语还是表语，都无被动的意味。因为dress neself in等于 be dressed in；seat neself n等于 be seated n；absrb neself in等于be absrbed in。这种现象缘于反身代词的用法：主语和宾语为同一人，主语是动作的发出者，又是动作的承受者，这就出现了被动语态或过去分词不表示“被动”的语言现象。
三、过去分词作状语过去分词（短语）作状语，表示动作发生的背景或情况，其逻辑主语就是句子的主语。过去分词（短语）在句中作状语可以表示时间、原因、条件、让步、方式或伴随等。1. 表示时间过去分词（短语）作时间状语，相当于一个时间状语从句。Asked abut his impressin f the apartment, he made n answer.= When he was asked abut his impressin f the apartment, he made n answer.当被问到他对公寓的印象时，他没有回答。
2. 表示原因过去分词（短语）作原因状语，相当于一个原因状语从句。Seriusly injured, he had t be taken t the hspital.= Because he was seriusly injured, he had t be taken t the hspital.由于他伤得很严重，只能把他送到医院。Deeply mved by the stry, the children began t cry.= Because they were deeply mved by the stry, the children began t cry.由于被这个故事深深地感动了，孩子们哭了起来。
3. 表示条件过去分词（短语）作条件状语，相当于一个条件状语从句。United, we stand; divided, we fall.= If we are united, we stand; if we are divided, we fall.团结则存，分裂则亡。
4. 表示让步过去分词（短语）作让步状语，相当于一个让步状语从句。Rejected many times, he didn't lse heart.= Thugh he was rejected many times, he didn't lse heart.他虽然被拒绝了多次，但并没有失去信心。
5. 表示方式或伴随过去分词（短语）作方式或伴随状语，可以转换成一个并列句。The by slid ut f his rm, fllwed by his pet dg.= The by slid ut f his rm and was fllwed by his pet dg.那个男孩溜出了房间，后面跟着他的宠物狗。
注意：（1）过去分词（短语）作状语，前面可以带有相应的连词（词组），如when，until， thugh，althugh，as if，as thugh，if，unless等，表时间、让步、方式、条件等。When（they are）expsed t light, ptates will turn green.马铃薯在光的照射下会变绿。（2）句子主语和过去分词（短语）之间是被动关系，和现在分词（短语）之间是主动关系。试比较：Caught in a heavy rain, he was late fr the interview.由于碰上了一场大雨，所以他面试迟到了。Lking ut f the windw, I saw sme students sweeping up the bits f paper.朝窗外望去，我看见一些学生正在清扫纸屑。
（3）过去分词（短语）作状语时，其逻辑主语与句子的主语要一致。如果主语不一致，要在分词前加上逻辑主语，构成独立主格结构。If caught, the plice will punish the thief.（×）If caught, the thief will be punished by the plice（√）小偷如果被抓，会受到警方的惩罚。The by rushed int the classrm, his face cvered with sweat.（his face是分词cvered的逻辑主语）那个男孩跑进教室，脸上全是汗。
（4）有些过去分词已形容词化，作状语时表示主语的某种情绪或状态。常见的这类形容词化的过去分词有satisfied，surprised，interested，mved，wrried，pleased，disappinted等。Disappinted at the examinatin result, the girl std there withut saying a wrd.因为对考试成绩很失望，那个女孩站在那儿一句话也没说。
