作状语，与逻辑主语之间是被动关系
作状语，与逻辑主语之间是主动关系
1.过去分词作表语的用法。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。He lked wrried after reading the letter.看完信后，他显得很忧虑。When we heard f it, we were deeply mved.当我们听说了这件事，我们深受感动。
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 cup is brken.杯子碎了。(系表结构)The cup was brken by Tm.杯子是汤姆打碎的。(被动语态)
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：
surprising令人吃惊的surprised感到吃惊的
frightening令人害怕的frightened感到害怕的
discuraging令人泄气的discuraged泄气的
disappinting令人失望的disappinted感到失望的
感觉类及物动词的现在分词与过去分词作表语的区别
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。The frightened lk n her face suggested that she was frightened by the frightening scene.她脸上害怕的表情表明她被这恐怖的现场吓着了。
1.过去分词(短语)作状语，表示被动的或完成的动作，这时句子的主语和过去分词之间为逻辑上的被动关系。Written in a hurry, this article was nt s gd.因为写得匆忙，这篇文章不是很好。本句中的written in a hurry为过去分词短语作状语，表示这篇文章是被写的，而且已经被写完。过去分词通常在句中作时间状语、原因状语、条件状语、让步状语、方式状语和伴随状语等。
(1)过去分词作时间状语，在句中相当于一个时间状语从句。Asked abut his address(＝When he was asked abut his address), the by didn’t respnd.问及他的地址时，小男孩没有作答。(2)过去分词作原因状语，在句中相当于一个原因状语从句。Annyed at the decisin(＝As he was annyed at the decisin), he refused t attend the meeting.由于对这个决定很生气，他拒绝参加会议。
(3)过去分词作条件状语，在句中相当于一个条件状语从句。Heated t a high temperature(＝If it is heated t a high temperature)，water will change int vapr.如果加热到高温，水就能变成蒸汽。(4)过去分词作让步状语，在句中相当于一个让步状语从句。Thugh warned f the strm(＝Thugh they had been warned f the strm), the farmers were still wrking in the fields.尽管被警告过有暴风雨，农民们仍然在田地里劳作。
(5)过去分词作方式、伴随状语，在句中相当于一个并列句。Fllwed by a grup f students，the teacher entered the classrm.＝The teacher entered the classrm and he was fllwed by a grup f students.老师走进教室，后面跟着一群学生。注意：过去分词(短语)作状语时，前面有时可以加上when, if, while, thugh, even if, until, unless等连词，这种结构可以看作是一种省略的状语从句(省略部分多为“主语＋be的多种形式”)。需要注意的是，省略的主语必须和主句的主语相同或为it。Even if invited(＝Even if I’m invited)，I wn’t take part in the party.即使受到邀请，我也不会参加这个聚会的。
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。这样的过去分词及短语常见的有：lst in(陷入某种状态)、seated(坐着的)、hidden(躲着)、lst/absrbed(沉溺于)、dressed in(穿着)、tired f(厌烦了)等。 Lst/Absrbed in deep thught, she didn’t hear the sund.由于陷入沉思，所以她没有听到那个声音。Dressed in a new dress, she lks very beautiful.穿着一件新衣服，她看上去很漂亮。
2.过去分词作状语时的位置。过去分词作条件、原因及时间状语时，通常放在句首；作伴随、结果状语时，通常放在句末；作方式状语时，一般放在句末，有时也放在句首；作让步状语时，一般放在句首，有时也放在句末。Tld that his mther was ill, Li Lei hurried hme quickly.(原因状语)得知母亲生病了，李雷迅速赶回了家。The ld man walked int the rm, supprted by his sn.(方式状语)老人在儿子的搀扶下走进了房间。
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。【助记】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。Used fr a lng time, the bk lks ld.(动宾关系)由于用了很长时间，这本书看上去陈旧。
过去分词与现在分词作状语的区别
Using the bk, I find it very useful.(主谓关系)在使用这本书时，我发现它很有用。注意：无论是现在分词还是过去分词，其逻辑主语必须和句子的主语一致。如果不一致，则必须用状语从句、独立主格结构等其他表达形式。If caught, the plice will punish the thief.(　×　)If caught, the thief will be punished by the plice.(　√　)If the thief is caught, the plice will punish him/her.(　√　)
(1)作表语：过去分词表示人或物的心情或状态等，也可以理解为心情或状态受到外界影响，有“感到…”之意；动词-ing形式则表示人或物的自身特征，有“令人……“之意。(2)作状语：过去分词与其逻辑主语之间是被动关系，往往表示完成；动词-ing形式与其逻辑主语之间是主动关系，一般表示动作正在进行。
过去分词与动词-ing形式的区别
