分词作状语-独立主格
分词和分词短语作状语时，可以表示时间、原因、条件、让步、方式和伴随情况。在表示时间、原因、条件、让步和方式时，通常可转换为相应的状语从句，表示方式和伴随情况时，可以转换为一个并列的谓语成分。
例如：Seeing the teacher entering the room,the students stood up.(=When the students saw the teacher entering the room,they stood up.)学生们看见老师走进房间，都站了起来。
Heated,ice will be changed into water.(=When it is heated...)当冰加热时，它就会变成水。(条件、时间)
Being excited, I couldn’t go to sleep.(=As I was excited,I couldn’t go to sleep.)我兴奋得睡不着觉。(原因)
I stood there, listening to the broadcast.(=I stood there and listened to the broadcast.)我站在那儿听广播。(伴随)
The children went away laughing.(=The children went away.They laughed as they went.)孩子们笑着走开了。(行为方式)
Knowing all this,they made me pay for the damage.(=Although they know all this...)他们尽管了解这一切，还是要我赔偿损失。
(3)分词作状语与主语的关系。
A. 现在分词作状语时，现在分词的动作就是句子主语的动作，它们之间的关系是主动关系。
例如：He went out shutting the door behind him.他出去后将门随手关上。
Not knowing what to do, he went to his parents for help.由于不知如何办是好，他去找父母帮忙。
B. 过去分词作状语时，过去分词表示的动作是句子主语承受的动作，它们之间的关系是被动关系。
例如：Given more attention,the trees could have grown better.如果对这些树多关心一些，它们本来会长得更好。
Faced with difficulties,we must try to overcome them.在遇到困难的时候，我们必须设法克服。
(4)分词作状语时前面可用连词。
when,while,once,if,unless,though等引导的状语从句，若其主语与主句主语相同时，可保留该副词连接词，其余部分则化简为分词短语。
例如：When (being) free，I’ll fetch you.有空时，我会来接你。
While walking along the street early in the morning,he saw her.一早在街上散步时，他看到了她。
If falling ill,I’ll see my doctor.如果生病我会去看医生。
Once completed,this power station supplies the nearby towns and villages with electricity.这个电站一旦建成，将向附近的城乡供电。

Though knowing the truth,he remained silent.虽然他知道实情，却保持沉默。
Unless (being) rich,I am not going abroad.除非有钱，要不然我是不会出国的。
(5)分词作状语时，要特别注意其逻辑主语须和谓语动词的主语一致，否则分词必须有自己的主语。这种带主语的分词结构称作分词的独立结构，或独立主格。
例如：The rain having stopped,the soldiers continued their match.雨停后，战士们又继续行军了。
The boys returned,their face covered with sweat.孩子们回来了，满脸是汗。
〈注〉有时也可用“with(或without)+名词(或代词宾格)+分词”的结构，表示伴随情况。
例如：He fell asleep with the lamp burning.他亮着灯睡着了。
The teacher entered the classroom,with a bag (being)in his hand.老师进了教室，手中提着一个包。
(6)分词作连词引导状语从句。
这些分词有:provided (or provided that)，providing that, supposing,seeing (that), considering 等。
例如：You can arrive in Beijing earlier for the meeting provided you don’t mind taking the night train. 如果你不介意搭夜班火车，你就能早点儿到北京开会。
I’ll go,providing you go too. 如果你去的话我就去。
Supposing it rains,what shall we do?假如要下雨的话，我们怎么办?

Considering he has been learning English only for a year,he speaks it quite well.考虑到他学习英语才一年，他讲得相当不错。
(7)动词不定式和分词作状语的区别。
A. 分词作状语一般表示伴随，而不定式常常表示目的。
例如：They stood by the roadside talking about the plan.他们站在路边谈论着这个计划。(伴随)
They stood by the roadside to talk about the plan.他们站在路边，为的是谈论这个计划。(目的)
B. 分词作状语放在句子开头，除表示原因之外，有时表示时间或条件。动词不定式作状语时，除了表示目的以外，还表示结果或原因。
例如：Reading attentively,he forgot the time for lunch.由于在专心读书，他忘了吃午饭的时间。(原因)
Reading carefully,he found something he had not known before.他仔细读书时，发现了一些从前不知道的东西。(时间)
Reading carefully,you’ll learn something new. 只要你仔细阅读，你会学到一些新的东西。(条件)

We are glad to hear the news.我们很高兴听到这消息。(原因)
2) 现在分词和过去分词作状语时的用法比较
不管是现在分词还是过去分词作状语，如果单独作状语，其逻辑主语必须和主句的主语一致。分词作状语通常可以转换成一个相应的状语从句，如果状语从句中的谓语动词为被动结构，就用过去分词；如果状语从句中的谓语动词为主动结构，就用现在分词。有时为了强调，分词前可带连词when, while, if, though, as if, unless等一起作状语，以便使句子的意思更清楚、更连贯。例如：
Working hard (If you work hard), you will succeed.
如果你努力，你会成功的。
[b] Defeated (= Though he was defeated), he remained a popular boxer.
虽然他被击败了，但他仍然是一个受人喜爱的拳击手。
独立主格
（一）：独立主格结构的构成：
名词(代词)+现在分词、过去分词；
名词(代词)+形容词；
名词(代词)+副词；
名词(代词)+不定式；
名词(代词) +介词短语构成。
（二）独立主格结构的特点：
1）独立主格结构的逻辑主语与句子的主语不同，它独立存在。
2）名词或代词与后面的分词，形容词，副词，不定式，介词等是主谓关系。3）独立主格结构一般有逗号与主句分开。
举例：
The test finished, we began our holiday.
= When the test was finished, we began our holiday.
考试结束了，我们开始放假。
The president assassinated, the whole country was in deep sorrow.
= After the president was assassinated, the whole country was in deep sorrow.

动词过去分词及独立主格结构的用法 一、过去分词的定义及其基本形式 1．过去分词是动词的另一种非限定形式，过去分词具有动词、形容词和副词的特性，可以带宾语或受状语修饰。过去分词和宾语或状语一起构成过去分词短语。如： （1）spoken English 英语口语（过去分词具有形容词的特性，作定语） （2）Given more time, we could do it much better. =If we were given more time, we could do it much better. 多给点时间，我们会做得更好些。 （过去分词具有动词的特性，有自己的宾语more time，构成分词短语；过去分词短语在句中作状语，具有副词的特性。） 2．过去分词的基本形式 （1）规则动词的过去分词由动词＋ed构成 （2）不规则动词的过去分词须逐个记忆。 （3）不规则动词的过去分词表示完成，如： fallen leaves =leaves which have fallen落叶 （4）及物动词的过去分词表示被动或完成，如： the machines used in the workshop =the machines which are used in the workshop 车间用的机器（及物动词的过去分词表示被动） I heard the door opened. =I heard the door has been opened. 我听见门被打开了。（及物动词的过去分词表示被动和完成） 二、过去分词的句法功能 过去分词是一种非谓语动词，在句中不能单独做谓语。但它具有形容词和副词的特性，故在句中可以作定语、表语、宾语补足语和状语。
现在分词 Form: ?doing ?having done（先后关系） 现在分词表示主动含义或动作正在进行。 Exercise: 划出句中的现在分词，并指出它在句中做何成分。 1. The three contestants were sitting at their desks on the stage, waiting. 2. Hearing the news, he jumped with joy. 3. Having finished his homework, he went out. 4. People living in the cities used to regard farming as boring and backward. 5.

The people take part in a variety of exercise They can keep healthy. 3. The research at Sunqiao produces seeds. The seeds help farmers grow better crops. 4. People used to regard farming as boring and backward. These people live in cities. 5.Do you know the boy? He is standing under the tree. 6. The spiders store the mice for later. The mice serve as a source of food. Exercise: compare The swimming pool is clean and big. The swimming boy is his brother. The big writing desk is very expensive.

垂悬分词和独立主格结构 I.一般来讲，分词或分词短语在句子中充当状语时，其逻辑主语与句子主语一致 如Opening the drawer he took out a revolver．（其中opening的逻辑主语是句子主语he） II.当分词的逻辑主语与句子的主语不一致时，则应将分词的逻辑主语补出来 如George yawning，the conversation dropped．这种分词结构被称作独立主格结构（独立主格结构（Absolute Structure）是由名词或代词加上分词等构成的一种独立结构。独立主格结构中的名词或代词与其后的分词等构成逻辑上的主谓关系。这种结构的位置相当灵活，可置于主句前、主句末或主句中，常由逗号将其与主句分开。需特别注意的是，独立主格结构与主句之间不能使用任何连接词） §独立主格结构基本构成形式 【名词(代词)+现在分词（过去分词；形容词；副词；不定式；名词；介词短语）】，在句中一般作状语，表示时间、条件、原因、伴随状况等，还可以作定语 1. 名词(代词)+现在分词 There being no bus, we had to walk home.（原因） 由于没有公共汽车，我们只好走回家。 2.名词(代词)+过去分词 The workers worked still harder, their living conditions greatly improved. （原因） 由于工人们的生活条件大大提高，他们工作得更起劲了。 He was listening attentively in class, his eyes fixed on the blackboard.（伴随状况） 他上课专心听讲，眼睛紧盯着黑板。 3.名词(代词)+不定式 在“名词/代词+动词不定式”结构中，动词不定式和它前面的名词或代词如果存在着逻辑上的主谓关系，动词不定式则用主动的形式；如果是动宾关系，则用被动形式。 The four of us agreed on a division of labor, each to translate a quarter of the book. 我们四人同意分工干，每人翻译全书的四分之一。 Many trees, flowers, and grass to be planted, our newly-built school will look even more beautiful. 种上许多的树、花和草后，我们新建的学校看上去将更美。 4.名词(代词)+形容词 The Trojans asleep, the Greek soldiers crept out of the hollow wooden horse． 特洛伊人睡着了，于是希腊士兵从中空的木马里悄悄爬了出来。 Computers very small, we can use them widely. 电脑虽小，我们却能广泛地利用它们。 5.名词(代词)+副词 The meeting over, our headmaster soon left the meeting room. 散会了，校长很快就离开了会议室。 The lights off, we could not go on with the work. 灯熄了，我们不能继续工作了。 6.名词(代词)+名词 His first shot failure，he fired again． 他第一枪没击中，又打了一枪。 Two hundred people died in the accident, many of them children. 两百人死于事故，其中有许多儿童。
高中英语分词作状语精讲(附作文写作亮点2) 难点形成原因: 1. 对在句中作时间、条件、原因还是别的状语不是很清楚。 2．分不清何时用现在分词、何时用过去分词。 解决办法： 1．理解分词作状语时可以转换成相应的状语从句。 2．分清何时用现在分词、何时用过去分词。 用法讲解： 1.分词或分词短语作状语时，可以表示时间、原因、让步、条件，方式或伴随状况。通常可转换成相应的状语从句；表示方式或伴随状况时可以转换成并列句或非限制性定语从句。 例如： Put into use in April 2000 (=When it was put into use in April 2000), the hotline was meant for residents reporting water and heating supply breakdowns. 分词短语作时间状语 Blamed for the breakdown of the school computer network (=Because she was blamed for the breakdown of the school computer network), Alice was in low spirits. 分词短语作原因状语

(= and think that all children like these things.) 分词短语作伴随状语 2. 有时为了强调，分词前可带when, while, if, though, as if, unless等连词一起作状语，以便使句子的意思更清楚、更连贯。 例如： When comparing different cultures, we often pay attention only to the differences without noticing the many similarities. Though tired, he still continued reading. 3. 现在分词和过去分词作状语时的用法比较。 不管是现在分词还是过去分词单独作状语，其逻辑主语必须与主句的主语一致。分词作状语通常可转换成一个相应的状语从句或并列句，如果状语分句或并列句中的谓语动词为被动结构，就用过去分词；如果状语分句或并列句中的谓语动词为主动结构，就用现在分词。例如： When compared with the size of the whole earth , the biggest ocean does not seem big at all. （04湖北） 分词部分相当于When the biggest ocean is compared with the size of the whole earth, 主语与

分词作状语用法知识点详解和辨析 分词做状语，在我们的英语表达里有何用法与见解呢?以下是小编给大家带来分词作状语用法，以供参阅。 英语分词的形式非谓语动词主动形式被动形式意义 现在分词一般式doing being done与句中谓语动作几乎同时发生 完成式having donehaving been done先于句中谓语动作发生，强调时间先后 过去分词done-----------------与句中主语为逻辑上的被动，表完成 英语分词的意义在英语中，分词包括现在分词与过去分词两种形式，即-ing与-ed。一般情况下，从时态和语态两种角度来讲，现在分词表示主动、进行;而过去分词表示被动与完成。 对于分词的含义，我们从以下两组词语为例进行分析： 1)the sinking ship 正在下沉的船fallen leaves 落在地上的树叶\ the boiled water 凉白开水 1)从语态角度来看，现在分词表示主动含义，它与所修饰的名词构成主谓关系。the sinking ship 可以改写为the ship that is\ was sinking, 这里的ship相当于sink的逻辑主语。其次，从时态角度看，现在分词一般表示进行的动作，相当于一个进行时态;此外，它还可以表示一般的动作，相当于一个一般的时态。综上，现在分词的意
义有两种：主动进行的动作和主动一般的动作。 2)从语态角度来看，过去分词可以表示被动含义也可以表示主动含义，即动词不同则含义不同。及物动词的过去分词只有被动含义，如the boiled water=the water that was boiled \ the water that has been boiled. 而不及物动词没有被动只有主动，如the sunken ship= the ship that has sunken.但是不及物动词的过去分词出现频率较低，常见的过去分词多为及物动词的过去分词，表达被动含义。其次，从时态角度看，过去分词具有一般动作或完成动作的含义，相当于一般时态或完成时态。不及物动词只具有完成动作。 英语分词作状语的用法分词做状语时可以表示时间、原因、结果、条件、方式、让步、伴随、比较。 四、分词作状语的原则：其逻辑主语必须和句子的主语保持一致。 常见分词作状语的情况举例： 表条件：Given more time, I would be able to complete the work. \ United we stand; divided we fall. (合则兴，分则亡) 表时间：Walking in the street,I saw him. 表原因：Getting hurt badly in the match, he has to stay at home. 表伴随：Watching the TV play, she burst out crying. 表让步：Having lived in China for years, he still cant speak Chinese well. 表结果：I went home, finding the door locked.
