二、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, 表状态)*The cup was brken by Tm. 杯子是汤姆打碎的。(被动语态, 表动作)

三、过去分词与动词-ing形式作表语的区别英语中有很多与感觉有关的及物动词, 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、人的声音或表情等; 动词-ing形式表示主动意义, 即“令人有某种感觉的”, 多用来修饰物。常用的这类词有:
*We were surprised at what he said at the meeting. 我们对他在会上讲的话感到惊讶。*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。

Ⅱ. 过去分词作状语一、过去分词作状语的类型过去分词作状语, 可以表示时间、让步、条件、原因、方式和结果等, 相当于一个状语从句。其逻辑主语为主句的主语, 且与主句主语之间构成逻辑上的被动关系。1. 作时间状语。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。
*(2018·北京高考)Ordinary sap, used crrectly, can deal with bacteria effectively. =When it is used crrectly, rdinary sap can deal with bacteria effectively. 普通肥皂被正确使用的时候, 也是可以有效除菌的。2. 作原因状语。相当于原因状语从句或并列句。*Absrbed in painting, Jhn didn’t ntice evening appraching. = Because Jhn was absrbed in painting, he didn’t ntice evening appraching. = Jhn was absrbed in painting, s he didn’t ntice evening appraching. 由于专心画画, 约翰没有注意到夜幕正在降临。
3. 作条件状语。相当于条件状语从句。可加连词if, unless等转换成条件状语从句。*Used with care, ne tin will last fr six weeks. =If it is used with care, ne tin will last fr six weeks. 如果用得仔细的话, 一个罐子可以用六周。
4. 作让步状语。相当于让步状语从句。有时可加althugh, thugh, even if, even thugh, whether. . . r等连词转换成让步状语从句。*Defeated by his ppnent, he never gave up any hpe. = Althugh he was defeated by his ppnent, he never gave up any hpe. 尽管被对手击败, 但是他从没放弃希望。
5. 作方式、伴随状语。相当于and连接的并列句。*She accepted the gift, deeply mved. = She accepted the gift, and she was deeply mved. 她接受了礼物, 被深深地感动了。
【名师点津】过去分词(短语)作状语表状态　　值得注意的是, 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)等。*Lst in thught, he didn’t hear the bell. 由于陷入沉思之中, 他没有听到铃声。
【即学活用】(1)语法填空①_________(cmbine) with Chinese traditinal medicine, heat treatment is mreeffective. ②They _______(ffer) him a very gd jb, but he turned it dwn. ③Greatly ________(inspire)by what he did, I jined him in helping thers. ④ _______(visit) many times, the place is still wrth visiting again. ⑤The master entered the rm, ________(fllw) by his dg.
(2)句型转换。①When it is seen frm the tp f the hill, the twn lks mre beautiful. →____________________________________________________ ②Because they were deeply mved by the film, the children began t cry. →______________________________________________ ③If we were given mre time, we culd d it much better. →_________________________________________
Seen frm the tp f the hill, the twn lks mre beautiful.
Deeply mved by the film, the children began t cry.
Given mre time, we culd d it much better.  
④The president f the cmpany came t the factry, and he was fllwed by smewrkers. →___________________________________________________________________ 
The president f the cmpany came t the factry, fllwed by sme
二、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。
三、过去分词的独立结构作状语过去分词作状语时, 有时在分词前加上自己的逻辑主语, 这种带有自身逻辑主语的过去分词被称为过去分词的独立结构。过去分词的独立结构在句中作状语时, 通常可表示时间、原因、条件等。*Much time spent sitting at a desk, ffice wrkers are generally trubled by health prblems. 很多时间都坐在办公桌旁, 办公室职员一般都受到健康问题的困扰。
【即学活用】用独立主格结构作状语改写句子。(1)After the lecture was given, a lively questin-and-answer sessin fllwed. →_______________, a lively questin-and-answer sessin fllwed.  (2)The factry prduced many famus cars, nne f which were shipped t freigncuntries. →The factry prduced many famus cars, ____________________________________.  (3)Because extra mney was given t the pr, he felt very happy. →__________________________, he felt very happy.  
The lecture given
nne f them shipped t freign
Extra mney given t the pr
四、过去分词与动词-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动宾关系, 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主谓关系, 即表示主动, 一般表示动作正在进行。*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。*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。
【巧学助记】　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。
【名师点津】分词作状语误区警示无论是动词-ing形式还是过去分词, 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. ( )
【即学活用】语法填空(1) ______________(finish) their wrk, they went hme t have a rest.  (2)_______ (grw) in rich sil, these seeds can grw fast. (3)_________ (impress) by the beautiful scenery, I frgt t g back hme in time. (4)________ (lk) ut f the windw, I fund many children playing n theplaygrund.
