41、。(2)“get过去分词”也能用于被动结构和系表结构，用于被动结构时，它强调动作的发生；用于系表结构时，它强调状态的变化。*Most of the skin on his face got burnt away in the fire.在火灾中，他脸上的皮肤大部分烧掉了。(3)过去分词作表语与被动语态的差异。作表语用的过去分词表示主语的特点或所处的状态，强调主谓关系。这种结构中的过去分词前可加quite, very, rather等修饰词。被动语态表示动作，强调动宾关系，绝大多数被动结构中的行为执行者还可以用by短语来表示。* The novel is well written.(系表结构)这

42、部小说写得很好。* The novel is written by Lu Xun.(被动语态)这部小说是鲁迅写的。(4)有些过去分词作表语时，相当于形容词，且大部分已转化为形容词，常见的有：delighted，disappointed，discouraged, drunk, amused, astonished, hurt, interested，crowded, tired, satisfied, pleased, surprised, worried，excited, married, puzzled, upset等。*On hearing the good news everyone w

43、as very excited.听到这个好消息，大家都很激动。*The book is very interesting and Im very interested in it.这本书很有趣，我对它很感兴趣。【名师点津】充当形容词的动词-ing形式和过去分词的区别：动词-ing形式一般具有主动意义，表示“起某种作用”，多用于说明事物本身的性质、特征及给人的感觉；过去分词一般具有被动意义，表示“受某种影响”，多用于形容人的感觉。常用的这类词有： They were shocked to know that some people died of the unknown disease.得知一些

44、人死于这种未知的疾病，他们感到震惊。Although the little girl was frightened, she answered in a calm voice.虽然小女孩很害怕，但她还是用平静的声音回答。【学法点拨】有些使令动词，如dress, seat, absorb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 oneself in等于be dressed in; seat oneself on等于be seated on; absorb oneself in等于be absorbed in，这种现象缘于反身代词的用法：主语和宾语同为一人，主语是动作的发出

45、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。二、过去分词作状语过去分词作状语时，过去分词所表示的动作与句子主语之间构成逻辑上的动宾关系。1原因状语*Choked by the heavy smoke, he could hardly breathe.他被浓烟呛了，几乎不能呼吸了。*Caught in a heavy rain, he was all wet.因为淋了一场大雨，所以他全身都湿透了。2时间状语*Left to itself in the room, the baby began to cry.当被独自留在房间里时，婴儿哭了起来。*Asked why

46、he did it, the monitor said it was his duty.当被问及他为什么要这么做时，班长说这是他的职责。3条件状语*Seen in this aspect, the matter isnt as serious as people generally suppose.如果从这个角度看，问题并不像人们普遍认为的那样严重。*Grown in rich soil, these seeds can grow fast.如果被种在肥沃的土壤里，这些种子能长得很快。4方式或伴随状语*Surrounded by his students, the professor sat

47、there cheerfully.那位教授在学生的簇拥下，兴高采烈地坐在那儿。*He stood there silently, moved to tears.他静静地站在那里，被感动得热泪盈眶。5让步状语*Beaten by the police and sent to jail, Gandi created the principle of nonviolent resistance first.尽管受到了警察的殴打并被投入了监狱，甘地却首创了非暴力抵抗的原则。*Defeated again, he didnt lose heart.虽然再次被击败，但他没有灰心。三、现在分词与过去分词作状

48、语的区别1逻辑关系现在分词作状语与过去分词作状语的最主要区别在于：两者与所修饰的主句的主语的逻辑关系的区别。(1)现在分词作状语时，现在分词所表示的动作与句子主语之间构成逻辑上的主谓关系。*He went out，shutting the door behind him.他出去后随手关上了门。(he是shut这个动作的发出者，构成逻辑上的主谓关系)*Not knowing what to do, he went to his parents for help.由于不知如何是好，他去找父母帮忙。(2)过去分词作状语时，过去分词所表示的动作与句子主语之间构成逻辑上的动宾关系。*Given more

49、 encouragement, the boy could have behaved better.如果多给这个男孩一些鼓励，他本能表现得更好。(句子主语the boy与give构成逻辑上的动宾关系)*Faced with difficulties，we must try to overcome them.在遇到困难时，我们必须设法克服。(3)部分过去分词来源于系表结构，作状语时不表示“被动关系”，其前不用being。常见的这种过去分词及短语有：lost in(陷入某种状态)，seated(坐着的)，hidden(躲着)，lost/absorbed(沉溺于)，born in(出生于)，dres

50、sed in(穿着)，tired of(厌烦了)等。*Lost/Absorbed in deep thought, he didnt hear the sound.因为陷入沉思中，所以他没有听到那个声音。*Born in this beautiful town, he hates to leave it.出生于这个美丽的小镇，他不愿离开它。2时间概念过去分词所表示的动作发生在谓语动作之前，或表示“一种状态”，与谓语动作同时发生或存在。现在分词的一般式(doing)表示的动作与谓语动作同时发生或在说话时正在进行。*Written in a hurry, this article was not
