语法知识篇：作状语的现在分词短语
现在分词短语可以用作状语，修饰句子中由谓语表示的主要动作。这个状语可以表示动作发生的时间、原因、结果、条件、方式或表示主要动作发生的伴随情况，通常相当于一个状语从句或并列分句。一般说来，这种结构的逻辑主语就是句子的主语。下面分述如下：
一、作时间状语
如果现在分词的动作和主谓语的动作同时发生，分词用一般式，有时其前可以加上连词while或when。例如：
①Hearing the news，they all jumped with joy.(＝When they heard the news，they...)
听到这个消息时，他们都高兴得跳了起来。
②Walking slowly across the grass，he pointed the gun at the lion and fired.
他慢慢地走过草地，把枪对准狮子就射击了。
③One day，while walking along the sands towards his boat，Crusoe saw in the sand the mark of a man's foot.
有一天，克鲁索沿着沙滩走向他的船时，在沙子里看见一个人的脚印。
如果现在分词的动作结束之后，谓语动词的动作才发生，现在分词应用完成式。这时分词所表示的动作有一定的持续性。如果用一般式就会给人感觉到似乎是"某人在做某事时就开始做某事"，容易产生误解。但是，如果现在分词是hear，see等表示感官的动词或是leave，arrive，turn，open等表示位置转换或情况改变的动词，现在分词所表示的动作发生后，主句的动作往往紧接着发生，那就不必用完成式，仍用一般式。例如：
①Having watered the flowers(＝After／When he had watered the flowers)，he began to cut the grass.
他把花浇好后，开始割草。
②Having eaten his dinner，the boy rushed out.
那男孩吃完了饭就跑出去了。
③Hearing the footstep below(＝When he heard the footstep below)，he rose and went to the top of the stairs.
听见下面脚步声，他站起身来走到楼梯口去。
④Seeing a large cake flying through the air，the driver pulled up quickly.
司机看见一只大蛋糕在空中掠过，赶紧刹车。
二、作方式状语
现在分词作方式状语很容易与伴随状语、同位语、定语相混淆。试分析下列句子：
...But later，people developed a way of printing，using rocks.
……但是以后，人们利用石块发展了印刷术。
有人对该句using rocks提出了以下看法：
1)把它视作相当于一个非限制性定语从句。
2)把它视作a way of printing的同位语。
3)把它视作状语，表示伴随情况或方式。
笔者赞成第三种看法，表示方式状语(但不是伴随状语)。因为句中using rocks表明人们用什么方法发明了一种印刷方法，是涉及到用how或by what means的回答问题，所以，如果把句中using前的逗号去掉，改为by，则句意保持不变。又如：
He earns a living by driving.他靠开卡车谋生。
They would be ableto reply to our signals by using similar methods.
他们将能用同样的方法回答我们的信号。
三、作目的状语例如：
①Pappy ran out to the gate and told him not to come fooling(＝to fool)round there no more.
巴比跑到大门口去叫他不要再到这儿来游荡。(钱歌川，《英语疑难详解》P237)
②The six blind men stood there begging for a meal.(＝in order to beg for a meal)六个瞎子站在那儿要饭。
四、作结果状语例如：
①I thought he was making fun of me，and ran faster than ever，reaching(＝so that I reached)the school yard quite out of breath.
我想他在拿我开玩笑，就越发跑得快了，到达校园时已经上气不接下气。
②Her husband died ten years ago，leaving her with three children to look after.她丈夫十年前去世了，撇下她和三个孩子。
五、作伴随状语
伴随状语的特点是：它所表达的动作或状态是伴随着句子谓语动词的动作而发生或存在的。例如：
①He sat in the armchair，reading a newspaper.
他坐在扶手椅里读报。
②All night long he lay awake，thinking of the problem.
他整夜躺在床上睡不着，思考着那个问题。
六、作原因状语
现在分词短语作原因状语，尤其是be，feel，know，recognize，fear等状态动词的现在分词(短语)，以及现在分词的否定式用作状语时，通常表示
原因。例如：
①Being sick，I stayed at home.我因病呆在家中。
②Not knowing her address，I can't write to her.由于不知道她的地址，我没法给她写信。
③Not having done(＝As he has not done)his homework，he stayed at home.
由于他没完成作业，只好呆在家里。
七、作条件状语例如：
Taking(＝If you take)the path that leads out of the town，you will come to a dense wood.
如果你沿着通向郊外的小道前进，就会走到一片密林处。
八、起补充说明作用
现在分词短语起补充说明的作用与伴随状语有些相似，但严格地说，它不是伴随状语，因为它所表达的情景不与句子的动作相伴而产生，实际上，它起着补充说明的作用，相当于一个并列分句，但比分句简洁、明快。例如：
①My train leaves at six，arriving in Chicago at ten.＝...and will arrive in Chicago at ten.
②The visiting Minister expressed his satisfaction with the talks，adding that he had enjoyed his stay here.＝...and added that he had enjoyed his stay here.

现在分词作状语 一、现在分词短语在句中可以作条件状语， 其逻辑主语须为句中的主语，该短语相当于一个条件状语从句。 Working hard, you'll succeed. = If you work hard, you'll succeed. 如果你努力工作，你会成功的。 Turning to the left, you will find the path leading to the park. = If you turn to the left, you will find the path leading to the park.如果转向左边，你将找到通向公园的小道。 二、分词短语在句中作让步状语 分词短语在句中作让步状语时，相当于一个让步状语从句，有时分词前可以带有连接词although, whether, even if, even though。 现在分词短语作让步状语，分词的逻辑主语是句中的主语，变成状语从句时，需用主动语态。 Weighing almost one hundred jin the stone was moved by him alone. = Although the stone weighted almost one hundred jin, it was moved by him alone. 虽然那块石头重将近一百斤，他一个人就把它挪动了。 三、分词短语在句中作结果状语 现在分词短语在句中可以作结果状语，它的逻辑主语便是句中的主语，该短语相当于一个结果状语从句，且用主动语态。分词短语在句中作结果状语时，通常位于句末，中间有逗号。有时为了加强语气，就在分词前加thus。 Their car was caught in a traffic jam, thus causing the delay. = Their car was caught in a traffic jam, thus it caused the delay.他们的车遇上交通阻塞，因而耽误了。 四、分词短语在句中表示方式或伴随情况 分词短语表示方式或伴随情况是比较常见的。它用来说明动作发生的背景或情况。一般情况下，现在分词所表示的动作与谓语所表示的动作同时发生，它的逻辑主语就是句中的主语，谓语动词作为主要动作，而现在分词表示一个陪衬动作，它没有相应的状语从句可以转换，但可以用并列句来转换。过去分词可以说明谓语动作的背景。过去分词与其逻辑主语之间有动宾关系。如： The children ran out of the room, laughing and talking merrily. The children laughed and talked merrily, and they ran out of the room. 那些孩子们跑出房间，愉快地笑着、说着。 Helped by their teacher, the students finished the task successfully. 在老师的帮助下，学生们成功地完成了任务。 五、现在分词短语作时间状语有以下三种情况： 1．分词动作一发生，谓语动作紧跟着发生，这时用现在分词的一般式作时间状语，其逻辑主语为句中的主语。常用的动词，如：hear, see, arrive, return, get to, look, open, close, leave, turn around, walk等，表示一个极短暂动作。 此种情况可以换作on+动名词，表示相同的意思。译作"一（刚）……就……"。 此种情况也可以换作是when引导的时间状语从句，该从句的动词多用一般过去时表示。Hearing their teacher's voice, the pupils stopped talking at once.
现在分词作状语 一、现在分词具有形容词和副词特征，用作副词时，充当时间、条件、原因、伴随、结果、方式以及让步状语。 1. 作时间状语，可改为时间状语从句，分词前可加while或when等连词。 When comparing different cultures, we often pay attention only to the differences without noticing the many similarities. =When we compare different cultures… (06全国) 2. 作条件状语，可改为条件状语从句，分词前可加once, until, if等连词。 Turning to the right, you will find the path leading to the park. =If you turn to the left … 3. 作原因状语，可改为原因状语从句。 Having been ill in bed for nearly a month, he had a hard time passing the exam. =Because/ As he had been ill in bed… (04福建) 4. 作结果状语，可改为which引导非限制性定语从句，分词前可加thus，加强语气。 Oil prices have risen by 32 percent since the start of the year, reaching a record $57.65 a barrel on April. =…, which reach a record $57.65 a barrel on April. (05山东) 5. 作让步状语，可改为让步状语从句，分词前可加although, though, even if, even though等连接词。 Though lacking money, his parents managed to send him to university. = Though his parents lack money, they … (02上海) 6. 作伴随状语，相当于and连接并列谓语。 About one-six undergraduates in Beijing this year are willing to spend as much as 2,6oo Yuan on driving courses, seeing it as an investment in their future. = …, and see it as an investment in their future. “You can’t catch me!” Janet shouted, running away =…and ran away (05全国) 7. 作方式状语。Jack came here, running. 二、现在分词的时态以及否定形式 分词的动作与谓语同时发生用一般式，可转化为on+动名词或when/while引导的时间状语从句，从句根据语境用一般过去时或过去进行时；分词动作先于谓语动词用完成式，可转化为after+动名词的一般式或after /when引导的时间状语从句，从句中用完成式；现在分词的否定式：not+分词构成。 Hearing his father’s voice, the boy turned off the TV set at once. = On hearing his father’s voice…或When the boy heard father’s voice, he… Having waited in the queue for half an hour, Tom suddenly realized that he had left his wallet at home. （04北京） =After waiting in the queue…或When Tom had waited in the queue for half an hour, he… 三、现在分词的逻辑主语及独立结构 分词作状语，逻辑主语与句子主语一致；如不一致时，分词带上自己的逻辑主语，形成独立主格结构。 误：While watching television, the doorbell rang. (05全国) 正：While watching television, we heard the doorbell ring. (05全国) 误：Being sunny, we went on a spring outing. 正：It being sunny, we went on a spring outing. 四、掌握以下区别 1. 首动词的用法区别
分词短语作状语的时态和语态 1. 分词的时态及其判断 * 过去分词没有时态形式的变化，因此been done 和had done 任何时候都不会出现。 * 现在分词有两种时态形式： 一般形式：doing 完成形式：having done * 判断分词用什么形式主要是要与句子中的主要动词行为发生时间进行对比，如果同时或相继发生，用一般式；如果分词的行为的发生时间早于主要动词的发生时间，则用完成式。例如：--Working there, we learned a lot from them. (劳动的同时学到了许多) --Looking out of the window, I saw groups of children play games. (先望出去，接着就看到，视线没有断开) -- Having finished his work, he went to help his classmates.(完成工作在前，帮助他人在后，中间有停顿) -- Not having done it right, I tried again. (没做好在前，明显停顿后再次尝试) * 伴随状语是与主要动词的行为同时发生的动作，如果有前有后就不成其为伴随，所引不能用完成形式having done 表示，否则就是逻辑错误。 2. 分词的语态及其判断
* 过去分词本身就表示被动 * 现在分词的被动语态同样有两种形式 一般式：being done 完成式：having been done * 主动与被动的判断主要是要找到分词的逻辑主语，一般说来，用作状语的分词，其逻辑主语就是句子的主语，它们之间有两种关系：逻辑主语是分词行为的支配者，即主谓关系——用现在分词主动形式表示； 逻辑主语是分词的行为对象，即动宾关系——用过去分词或现在分词的被动形式,分别表示： 过去分词——与主要动词先后发生，如： -- Inspired him, we decided to work harder. (被鼓励接下来决定更加努力) 现在分词一般式——与主要动词同时发生，如： -- Being surrounded, the enemy was forced to surrender.（被包围的同时被迫投降） 现在分词完成式——先于主要动词的动作，如： -- Having been asked to stay, I couldn't very well leave. (先被要求留下，（考虑后)觉得不好离开。 * 独立主格结构：
非谓语动词分词作状语
1 Adverb Clause of time时间状语从句 1 日子一天天过去，天气越变越坏 As the day went on, the weather got worse. 从句表示"随时间推移"连词用as，不用when 或while. 2 恰恰在交通灯变红时，我停住了车。 Just as / When the traffic light turned red, I stopped my car. ?不同时发生 1 我陪你直到你妈妈回家。 I will stay with you until your mother comes home. I won’t leave you until your mother comes home. 2 在拿到钱后，他迅速地离开了银行。 After he had got the money, he left the bank immediately. After having got the money, he left the bank immediately.

教学目标：讲解现在分词作状语及区分不定式、现在分词作状语的异同 重点难点： 1.现在分词和不定式作状语时，其逻辑主语一般应与句子的主语保持一致。 2.分词作状语时，要看它同句子主语之间的关系，以确定是现在分词还是过去分词。 3.注意非谓语动词与句子谓语动词的时间关系，以确定分词的时态形式 4、弄清非谓语动词与其逻辑主语的关系，以确定非谓语动词的语态形式. 5. 连词+分词形式（分词作状语的省略问题） 6.不定式作结果状语和现在分词作结果状语的区别。 7. 现在分词的独立主格结构和评价性状语 Step 1 lead in 朗读下面一首唐诗，找出其中的现在分词形式 Thinking in the Silent Night 静夜思 Before my bed there is bright moonlight 床前明月光 So that it seems that frost on the ground. 疑是地上霜 Lifting my head, I watch the bright moonlight. 举头望明月 Lowering my head, I dream tha t I’m home. 低头思故乡 Step2 现在分词作状语的意义 动词的现在分词作状语，修饰动词，相当于状语从句，在句中表示时间、原因、结果、条件、让步、行为方式或伴随情况及独立成分等，作时间、原因、条件、让步状语时多位于句首；作结果、伴随情况状语时常位于句末。 一. -ing分词短语作时间状语，代替一个时间状语从句(引导词有when ,while ) 温馨提示： 1．现在分词所表示的动作与主句的动作一般是同时发生，有时可由连词when, while引出。 2．现在分词所表示的动作一发生，主句的动作就立即发生时。如： When she saw those pictures，she remembered her childhood. =Seeing those pictures, she remembered her childhood. 看到那些画，她想起了自己的童年。 As soon as he heard the good news, he jumped with joy. =（0n）Hearing the good news, he jumped with joy. 他一听到这个好消息，就高兴地跳起来。 二．-ing分词短语作原因状语，相当于一个原因状语从句。(引导词有because ,as ,since) 如：As he was ill, he didn't go to school yesterday =Being ill, he didn't go to school yesterday. 由于生病，他昨天没有上学。 三．-ing分词也可作条件状语和让步状语，相当于一个条件状语从句。(引导词有if,unless,once) If you work hard, you will succeed. =Working hard, you will succeed. 如果你勤奋一点，你就会成功。 If you turn to the left, you will find the path leading to the school.
过去分词作状语 一．过去分词作状语的基本用法： 过去分词作状语主要是说明谓语动作发生的背景或条件；表示原因、时间、条件、让步、方式或伴随情况等。过去分词可置于主句前，也可置于主句后，用逗号与主句隔开。 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，所以他全身湿透了。Frightened by the n oise in the night, the girl didn’t dare to sleep in her room. 受到夜晚响声的惊吓，那姑娘不敢睡在她的房间。 2. 时间状语 Left to itself in the room, the baby began to cry.当被孤独地留在房间里时，婴儿哭了起来。 Asked why he did it, the monitor said it was his duty. 当被问及这件事时，班长说这是他的职责。 Approached in the dark, the lights looked lonely and purposeless. 在黑暗中走近时。那些电灯显得孤单而无意义。 3. 条件状语 Seen in this aspect, the matter isn’t as serious as people generally suppose. 如果从这个角度看，问题并不像人们一般预料的那样`严重。 Grown in rich soil, these seeds can grow fast. 如果种在肥沃的土壤里，这些种子能长得很快。 Given better attention, the accident could have been avoided. 要是多加注意，那次事故就能避免了。 Watered more, these cabbages could have grown better. 如果多浇点水，这些大白菜还可以长的得更好。 Compared with you, we still have a long way to go. 和你相比，我们还有很大的差距。 4. 方式或伴随状语 Surrounded by his students, the professor sat 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。The old man went into the room, supported by his wife. 那位老人在妻子的搀扶下,走进了房间。 5. 让步状语 Beaten by the police and sent to jail, Gandi created the principle of nonviolent resistance. 尽管受警察的殴打，被投入监狱，甘地却首创了非暴力抵抗的原则。Defeated again, he didn’t lose heart. 尽管再次被击败，但他没有灰心。
[非谓语动词和从句转换]状语从句与分词作 状语的转换 篇一: 状语从句与分词作状语的转换 状语从句与分词作状语的转换 时间、原因等状语从句可以转换成分词作状语，但这种转换是有条件的，也有一定的规律可循。[] 一、基本规则，也是最重要的规则是：从句的主语与主句的主语必须一致，变从句而主句不变。如： They did not go to the Summer Palace because they had a lot of work to do． 由于从句的主语与主句的主语都是they，可以把从句中because 和they去掉，把had变成having，即成现在分词短语作原因状语：Having a lot of work to do，they did not go to the Summer Palace． 二、从句如果表示主动、完成，进行的动作，则转换成现在分词；如果表示被动，则转换成过去分词。 1．When he heard a cry for help，he rushed out． 从句中，he was与heard是主动关系，表示“他听见”。则可变成现在分词作时间状语。 Hearing a cry for help，he rushed out． 2．The boy Cater went up to his teacher and said“sorry”because he
was great-ly touched by his words．从句中，he was touched是被动关系，是“孩子被深深地触动了”，则变成过去分词作原因状语。Greatly touched by his teache r’s words，the boy laterwent up to him and said“sorry”． 三、如果从句的主语与主句的主语不一致，该怎么办？请看下例： 1．As the heroes’ deeds moved them deeply，they decided to study even harder． 句中，主句的主语是they，而从句主语是the heroes’deeds，主语不一致，这时可以把从句变换一下句型，变成被动语态。即成As they w ere deeplymoved by the heroes’deeds．从句的主语与主句的主语都是they，就可转换成： Deeply moved by the heroes’deeds，they decided to study even harder． 下列的句子中主语也是不同的。 2．The professor came into the lab；a group of students followed him． 这是两个简单句，如果中间加个and也可看成并列句。但主语不同，可以先把第二句变成：He was followed by a group of students．全句就转换成： Followed by a group of students，the professor came into the lab． 四、如果看不出有从句，该怎么办？请看下例： He recognized the man who had been his classmate ten years
其实分词做伴随状语就是分词做方式状语的一种，伴随是一种方式。大多情况下其实方式状语从句都等于伴随状语从句。只有在just) as…so…结构中位于句首，这时as从句带有比喻的含义，意思是"正如…"，"就像"，多用于正式文体 分词短语作伴随状语 伴随状语的特点是：它所表达的动作或状态是伴随着句子谓语动词的动作而发生或存在的 1）现在分词与过去分词作状语的区别。 现在分词做状语与过去分词做状语的最主要区别在于两者与所修饰的主语的主动与被动关系的区别。 1）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。 ）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。 比如 The teacher came in the classroom with handing a book in his hand. with handing就是个例子 过去分词，现在分词都可以做伴随状语,即在某件事情发生的时候相伴发生的事情这个句子老师进入了教室，他是拿着本书进入教室的，在他进入教室的时候他的手中有一本书（相伴）知道意思了吧。 做题的时候要注意区分什么时候使用过去分词和什么时候使用现在分词做伴随状语。一般的无非又几种情况： 1，过去分词表示一种完成了的或者是被动意义的动作 分词作状语（关键找逻辑主语） a)放在句首的分词往往看作时间状语1以及原因状语2 1. Looking (when I looked) at the picture, I couldn't help missing my middle school days. 2.Seriously injured, Allen was rushed to the hospital. =As he was seriously injured, Allen was rushed to the hospital. b)放在句中或句末常常看作为伴随状态(并列句) The girl was left alone in the room，weeping（crying ）bitterly. (但注意特殊：Generally/frankly speaking... / taken as a whole(总的来讲）不考虑逻辑主语，看作为独立成分)
1、状语从句中的谓语动词是系动词be时: 1.1、当从句主语与主句主语相同时，只要去掉从句中的连接词与主语并把be改为being. 即可。 As he is a tailor, he knows what to do with this material. →Being a tailor, he knows what to do with this material. 1.2、从句的主句主语与从句主语不同时，只要保留从句的主语，其它变化同以上1.1。 As he is still a child, you shouldn't be too hard on him. →He being still a child, you shouldn't be too hard on him. 1.3、当从句是否定句时，只要在being 前加否定词not ，其它变化同以上1.2。 As he was no tall enough, he couldn't reach for the apple. →No being tall enough, he couldn't reach for the apple. 2、当从句的谓语动词是进行时态（现在进行时态或过去进行时态）时: 2.1、当从句主语与主句主语相同时，只要去掉从句中的引导词与主语并去掉助动词be保留现在分词即可。有时为了强调进行状态,亦在分词前保留being. While he was reading the book, he nodded from time to time. →While reading the book, he nodded from time to time 2.2、当从句与主句的主语不同时，除保留从句主语外，其他变化同以上2.1 When he was giving a telephone call, his wife was reading a novel. →He giving a telephone call, his wife was reading a novel 2.3、当从句是含not的否定句时，只要在being 前加否定词not ，其它变化同以上1.1与2.2 As Tom is not working in his office, No one receives the telephone. →Tom not working i n his office, no one receives the telephone. 3、当从句中的谓语动词为一般时态(一般现在时与一般过去时)的实义动词时： 3.1、当从句主语与主句主语相同时，只要去掉从句主语并将实义动词改为现在分词即可Look round when you cross the street. →Look round when crossing the street. 3.2、当从句与主句的主语不同时，只要保留主语，其他变化同以上3.1 When they left the airport, we waved again and again to them. →They leaving the airport, we waved again and again to them. 3.3、当从句是含not的否定句时，只要在现在分词前加not，其他变化同以上3.1与3.2 As he didn't know anything about the accident, he went to work as usual. →.Not knowing anything about the acc ident, he went to work as usual. 4、当从句的谓语动词是一般时态(一般现在时与一般过去时)的被动态时： 4.1、当从句主语与主句主语相同时，只要去掉从句中的连词与主语并去掉be保留过去分词即可。 As the teacher was surrounded tightly by a group of students, he couldn't get away. →Surrounded tightly by a group of students the teacher cou ldn't get away. 4.2、当从句与主句的主语不同时，只要保留主语，其他变化同以上4.1 A. As the car was trapped in the sand, we had to go for help. →The car trapped in the sand, we had to go for help. 4.3、当从句是含not的否定句时，只要在过去分词前加not外，其他变化同以上4.1与4.2 As he was not killed dead in the field, he escaped at the very night. →Not killed dead in the field, he escaped at the very night. 5、当从句的谓语动词是完成时态(现在完成时与过去完成时)时：
状语从句与分词作状语的转换 时间、原因等状语从句可以转换成分词作状语，但这种转换是有条件的，也有一定的规律可循。 一、基本规则，也是最重要的规则是：从句的主语与主句的主语必须一致，变从句而主句不变。如： They did not go to the Summer Palace because they had a lot of work to do． 由于从句的主语与主句的主语都是they，可以把从句中because和they去掉，把had变成having，即成现在分词短语作原因状语： Having a lot of work to do，they did not go to the Summer Palace． 二、从句如果表示主动、完成，进行的动作，则转换成现在分词；如果表示被动，则转换成过去分词。 1．When he heard a cry for help，he rushed out． 从句中，he was与heard是主动关系，表示“他听见”。则可变成现在分词作时间状语。 Hearing a cry for help，he rushed out． 2．The boy Cater went up to his teacher and said“sorry”because he was great-ly touched by his words． 从句中，he was touched是被动关系，是“孩子被深深地触动了”，则变成过去分词作原因状语。Greatly touched by his teacher's words，the boy laterwent up to him and said“sorry”． 三、如果从句的主语与主句的主语不一致，该怎么办？请看下例： 1．As the heroes' deeds moved them deeply，they decided to study even harder． 句中，主句的主语是they，而从句主语是the heroes'deeds，主语不一致，这时可以把从句变换一下句型，变成被动语态。即成As they were deeplymoved by the heroes'deeds．从句的主语与主句的主语都是they，就可转换成：Deeply moved by the heroes'deeds，they decided to study even harder． 下列的句子中主语也是不同的。 2．The professor came into the lab；a group of students followed him． 这是两个简单句，如果中间加个and也可看成并列句。但主语不同，可以先把第二句变成：He was followed by a group of students．全句就转换成： Followed by a group of students，the professor came into the lab． 四、如果看不出有从句，该怎么办？请看下例： He recognized the man who had been his classmate ten years before，so he wentover to say hello to him． 这句中，看不出有从句。so是并列连词，表示“因此，于是”等意思。这样一来，前面那一句就有表示原因的意味。这一句可以改写为： Because he recognized the man who had been his classmate ten years before，he went over to say hello to him．变成一个原因状语从句，即可转换成现在分词作原因状语。 Recognizing the man… 许多有and或没有and的并列句，只要主语一致，往往可能换成分词作伴随状语。如： The students went home from school；they talked and laughed．可转换成： Talking and laughing，the students went home from school． 五、如何判断要不要有一个Being？如： As he was very old，he had to give up his teaching． 可转换成：Being very old，he had to give up his teaching．再看下例： As he was moved by the story，he decided to learn from the heroes． 则转换成：Moved by the story，he decided to learn from the heroes．而不是Being moved… 为什么呢？原来前面的那一句的was是系动词（link verb），后面跟的是表语（形容词或名词）。又如：As he was an engineer，he knew exactly what to do． an engineer．是名词作表语，即可转换成：
分词作状语练习题解析 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 April000 , 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 , Alice was in low spirits. 分词短语作原因状语 Given time , he’ll make a fist-class tennis player. 分词短语作条件状语 We often provide our children with toys, footballs or basketballs, thinking 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.
高考英语专项复习：过去分词短语作状语分类练习 过去分词由于其内在的语法特征，常常有被动的含义。过去分词短语做状语，与主句主语之间常构成被动关系；所表示的时间，往往发生在主句谓语动词之前。一般来说，过去分词作状语，有三种不同的分类标准：1)就状语类型而言，过去分词短语在句子中常常做原因状语、条件状语、时间状语、伴随状语、让步状语等等；2)就逻辑关系而言，过去分词短语做状语时，既可以表示主句主语的状态特征、心理感受，也可以表示与主句主语之间构成被动完成关系; 3)就句子结构类型而言，分为过去分词短语作状语、含有过去分词的独立主格结构作状语、含有过去分词的with的复合结构作状语和if, unless, once, when, while, though, although, as if/though等引导的省略句作状语等。 （一）以逻辑关系为划分标准： 1.过去分词作状语表示主语的状态特征: 1)________ (gift) in music, he could many English songs when he was at the age of eight. 2)________ (experience) in teaching working, my maths teacher is popular with all the students. 3)________ (devote) to his career, the doctor worked day and night and fell down in Wuhan. 4)________ (skill) in paper cutting, my grandma got her fame in the paper-cutting competition. 5)________ (break) on the road ,the car can’t move forward a little. 2.过去分词作状语表示主语的心理感受: 1) _______(frighten) in the darkness, the little girl was not afraid to go home alone. 2)_______ (excite) about the final exam, my son jumped for joy. 3)_______ (satisfy) with what he did in the English Speech Contest, his teacher praised him. 4)_______ (disappoint) at the result of the game, he stood there, saying nothing. 5)_______ (puzzle) about how to do the maths problem, he asked his teacher for help. 3.过去分词作状语与主语之间构成被动关系: 1)_______ (help) by professor Liang, they have made a breakthrough in key breeding
现在分词短语作状语 一、时间状语 1.分词动作一发生，谓语动作紧跟着发生，这时用现在分词的一般式作时间状语，其逻辑主语为句中的主语。常用的动词，如：hear, see, arrive, return, get to, look, open, close, leave, turn around, walk等，表示一个极短暂动作。 此种情况可以换作on+动名词，表示相同的意思。译作"一（刚）……就……"。 此种情况也可以换作是when引导的时间状语从句，该从句的动词多用一般过去时表 示。如：Hearing their teacher's voice, the pupils stopped talking at once.（= On hearing their teacher's voice… = When they heard their teacher's voice, the pupils…）一听到教师的声音，学生们立即停止讲话。 2.谓语动作发生在分词所表示的动作过程之中，则用when /while+现在分词的一般式，分词的逻辑主语为句中的主语。此种情况可以用in+动名词的一般式代替。也可以换作when、while引导的时间状语从句，该从句的谓语动词用进行时态。如： Don't be careless when /while having an exam. = Don't be careless in having an exam. = Don't be careless when / while you are having an exam. 考试时不要粗心。 注：此结构中，不能用其他连接词替换when或while。 3.分词所表示的动作完成之后，谓语动作才发生，则要现在分词的完成式，即having done 的形式。分词的逻辑主语应是句中的主语。 这种情况可以用after+动名词的一般式表示。 这种情况也可以用after /when引导的时间状语从句来替换，该从句的谓语动词用过去完成式。如：Having finished his homework the boy was allowed to watch TV play. After having finished his homework, the boy… After /when he had finished his homework, the boy… 二、原因状语 1．分词短语在句中作原因状语时，相当于一个原因状语从句。与时间状语一样，也要注意分词所表示的动作与谓语动作的先后关系。当分词所表示的动作与谓语动作同时发生或几乎同时发生时，用分词的一般形式。此时分词的逻辑主语须是句中的主语。这样的原因状语可以换成because, as引导的原因状语，该从句谓语动词用一般过去时。 Not knowing how to work out the difficult physics problem, he asked the teacher for help. 因为不知道如何解这道物理难题，他求助老师。 = Because he didn't know how to work out the difficult physics problem, he asked…help. 2．当分词表示的动作发生在谓语动作之前，可以用现在分词的完成式在句中作原因状语，其逻辑主语须为句中的主语，该短语的作用相当于一个原因状语从句。该从句的谓语动词须用完成时。如： Having lived with the girl for 5 years, we all know her very well.
