1. 过去分词作表语与被动语态的差异
I was surprised at the news.(系表) I was brught up by my aunt.(被动)
被动语态表示动作,强调被动关系, 绝大多数被动结构中的行为执行者可以由by引出。作表语用的过去分词表示主语的特点或所处的状态,这种结构中的过去分词前可加quite、very、rather等修饰词。
We were pleased t see the city was surrunded by muntains.(2) Seen frm the train windw, the muntains lked massive. (3) The girl next t me was amazed t see such a view. (4) Attracted by the beautiful scenery, she decided t stay fr a cuple f days.【语法感悟】1.句(1)和句(3)中的黑体词都是过去分词作　　　。 2.句(2)、句(4)中黑体词是过去分词作　　　。过去分词与逻辑主语之间构成　　　关系。 
He is terrifying.(指他令人害怕)He is terrified.(指他感到害怕)Please describe a dg that is frightened.(狗受到了惊吓)Please describe a dg that is frightening.(狗是令人害怕的)
当表示主语处于某种状态,即“感到/觉得……”时,表语要使用过去分词; 而要表示主语具有“令人/使别人感到……”的特征/性质时,表语使用过去分词
2.过去分词与现在分词作表语的区别
二、过去分词(短语)作表语1.用法过去分词(短语)作表语表示主语所处的状态或主观心理感受，相当于形容词的作用。

3.过去分词(短语)作表语和动词-ing形式作表语的区别

Seen frm the tp f the hill,the schl lks like a big garden.Given mre attentin, the fire culd have been avided.Encuraged by the teacher, the girl was very happy.Left alne at hme,Jenny didn’t feel afraid at all.
过去分词作状语时,其表示的动作与句子的主语之间为逻辑上的被动关系。过去分词在句中可以作时间状语 、原因状语、条件状语、让步状语、伴随状语或方式状语。
(1) Asked why he was absent frm class, the little by lied that he was ill.(2) Given enugh water, the newly-planted trees wuld nt have died.(3) Absrbed in painting, Jhn didn’ t ntice evening appraching.(4) Published many times, this bk still sells well in the market.

过去分词(短语)与动词-ing形式作状语的区别
过去分词与句子的主语之间存在逻辑上的 ，即表示被动，往往表示完成；动词-ing形式与句子的主语之间存在逻辑上的 ，即表示主动，一般表示动作正在进行。
Seen frm the sky, ur city is very beautiful.(ur city与see之间是被动关系)Seeing it frm the sky, we find ur city is very beautiful.(we与see之间是主动关系)
过去分词与现在分词作状语的区别
分词在句子中作状语时, 分词的逻辑主语与句子的主语一致。使用哪种分词,取决于分词表示的动作与句子主语之间的关系: 被动关系用过去分词, 主动关系用现在分词。
Given a chance, we can surprise the wrld.There being n bus, we had t walk hme.
(2)过去分词作状语时，其逻辑主语必须与句子的主语保持一致(动词-ing形式作状语同样如此)，否则需加上自己的主语，构成独立主格结构。
(1)过去分词作状语时，有时为了强调，前面可带有连词，如: when, while, if, thugh, as if, unless, until等，以使句意表达得更清楚。
Unless cnstantly repeated, the English wrds are easily frgtten.
