过去分词做状语同步课堂教学设计

过去分词做状语同步课堂教学设计编写人：吴翔审批人：学习目标： 1. 熟记过去分词的基本用法；提升灵活运用能力。 2. 合作探究、大胆质疑；归纳过去分词的用法。 3. 激情投入学习；享受攻克难关的快乐。【使用说明】 1. 利用自主自习时间根据要求对导学案进行有效预习（约30分钟） 2. 1）15分钟自学、讨论 2）25分钟质疑、展示、点拨、巩固落实 3）5分钟当堂检测【课前预习】分词是动词的一种非谓语形式，主要起形容词和副词的作用，可以作定语、表语或是状语等分词有两种，一种是现在分词，一种是过去分词。这两种分词在句子中能担任的成分大体相同，主要是在“意思”上有主动和被动之分。过去分词有两大特点：一是表被动的概念；二是表动作已完成。过去分词在句中可用作定语、表语、宾语补足语或状语等成分。过去分词在句中作某种成分时，其逻辑主语一般为该分词所表示的动作的承受者。 1.作定语 1）及物动词过去分词既表被动，又表完成；不及物动词过去分词，只表完成。 boiled water开水、selected apples 精选苹果、spoken English英语口语、 iced beer冰镇啤酒、cooked food熟食、fried chips炸土豆条； fallen leaves落叶、 the risen sun升起的太阳 2）单个的过去分词作定语时，一般可以放在被修饰词语之前，也可以放在所修饰词语的后面。 The excited children didn’t know how to do with themselves. The meeting held yesterday was very important. 3）过去分词短语作定语时，须将分词放在被修饰的词语之后，功能相当于一个定语从句。Her daughter，brought up by me(=who was brought up by me)has begun to work now. 由我带大的她的女儿现在已经参加工作了。 2.作表语 1）当“人”做主语时用过去分词作表语，表示主语的状态或思想感情等。 He seemed quite delighted at the idea. 听到这个想法，他似乎很高兴。 2）过去分词作表语不要与被动语态混为一体。分词作表语表示主语的状态，而被动语态则表示被动的动作。比较： My glasses are broken.我的眼镜碎了。(状态) My glasses were broken by my son.我的眼镜被我儿子摔碎了。(动作) 3. 作宾补 1）过去分词用在表示“致使”含义的动词keep，leave，have，make, get等的后面。 They kept the door locked for a long time. 他们把门锁了好长一段时间。 Don’t leave the windows broken like this all the time. 不要让窗户一直像这样破着。 I have had my bike repaired. 我让人修了修我的自行车。 I raised my voice to make myself heard. 我提高了嗓门以便被人家听到。 2）过去分词常用在感官动词watch，notice，see，hear，listen to，feel，find等的后面。

分词作状语用法

分词作状语用法就是所有分词用法中最重要的,也就是最难掌握的。分词在句中作状语时,其逻辑主语必须就是句子的主语。一、现在分词作状语一、现在分词作状语,表主动、进行,相当于一个状语从句,根据需要可以使用被动式或完成式。Studying at the hometown, I enjoyed the happiest time during my life、 Being ill, she can't go to work today、 The children ran out of the room, laughing and jumping、 1、He sent me an e-mail, ________ to get further information、 A、hoped B、hoping C、to hope D、hope 2、Suddenly, a tall man driving a golden carriage ________ the girl and took her away, ________ into the woods、 A、seizing; disappeared B、seized; disappeared C、seizing; disappearing D、seized; disappearing 二、现在分词的时态语态 1、现在分词的一般式由“动词+ing”构成,其被动式为“being+动词过去分词”。例如:The students standing there are from Class Three、 The English novel being translated by the editor now will be completed in October、 2、现在分词的完成式由“having +动词过去分词”构成,其被动式为“having +been+动词过去分词”。例如:Having finished all the work, they had a good rest、 Having been given the right answer, the teacher asked me to sit down、 Given more time, we will finish the work in time、 3、现在分词的否定式为“not +动词-ing”,被动式的否定式为“not+being+动词过去分词”,其完成式的否定式为“not + having +动词过去分词”。例如:Not knowing what to do, he sat there crying、 Not being noticed by the public, the young writer felt a little pity、 1、_______ from heart trouble for years, Professor White has to take some medicine with him wherever he goes、 A、Suffered B、Suffering C、Having suffered D、Being suffered 2、Finding her car stolen, _______、 A、a policeman was asked to help B、the area was searched thoroughly C、it was looked for everywhere D、she hurried to a policeman for help 二、过去分词作状语过去分词只有一种形式,即done,表被动。 The mother came in, followed by her son、 When heated,water will be turned into steam、 Deeply moved by the film, we all cried、 Born into a poor family, he had no more than two years of schooling、 1._____ from the top of the TV tower, and we can get a beautiful sight of most of the city、 A、To see B、Seen C、Seeing D、See 2、_____ in 1613, Harvard is one of the most famous universities in the United Stated、 A、being founded B、Founded C、It was founded D、Founding 三、过去分词与V-ing作状语的区别 1、分词在句中作状语时,其逻辑主语必须就是句子的主语。

现在分词短语做状语

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。

过去分词作状语

过去分词作状语【观察】观察下列句子中过去分词的用法，然后加以总结。 1. Discussed many times, the problems were settled at last. 2. Looked at from a distance, the painting seems much more beautiful. 3. Caught in the rain on my way home, I had a bad cold. 4. Built thirty years ago the house still looks very beautiful. 5. The professor, followed by his assistants, walked out of the hall. 6. She sat by the window alone, lost in thought. 7. Satisfied with what he did, the teacher praised him in class. 8. Water can be changed into vapor when heated. 9. There is no point arguing about it; just do as told. 10. He rushed into the room, his face covered with sweat. [总结] 过去分词可作定语、状语、表语和宾语补足语。过去分词作状语应注意以下几点：一、过去分词作状语表示的意义 ●表示时间(如例句1)、条件(如例句2)、原因(如例句3)、让步(如例句4) 的分词短语相当于相对应的状语从句。 After they had been discussed many times, the problems were settled at last. If it is looked at from a distance, the painting seems much more beautiful. Because I was caught in the rain on my way home, I had a bad cold. Although it was built thirty years ago, the house still looks very beautiful. ●作方式状语或表示伴随情况，说明动作发生的背景或情况。一般情况下，分词所表示的动作和谓语动词所表示的动作同时发生。可转化成并列句。(如例句5-6) The professor walked out of the hall and he was followed by his assistants. She sat by the window alone, and she was lost in thought. 二、过去分词与句子主语之间的关系 ●过去分词作状语表示被动或完成的动作。其逻辑主语一般应与句子的主语一致。过去分词与句子主语之间通常存在逻辑上的动宾关系。(如例句1-5) 【难点点拨】分词作状语时，用现在分词还是过去分词，取决于分词与句子主语之间的关系。主动关系用现在分词，被动关系用过去分词。比较： Seeing from the top floor, we can find the garden more beautiful. Seen from the top floor, the garden looks more beautiful. ●有些过去分词或短语来源于系表结构，或某些动词后面加-ed转化来的形容词，作状语时不表被动而表主语的状态。常见的有lost(如例句6), seated, hidden, lost in, dressed in, faced with, absorbed in, surprised, disappointed, exhausted, frightened, satisfied(如例句7), tired等。三、“连词+过去分词”结构作状语过去分词作状语时，可在分词之前加某些连词，以表示强调。常用的有if, unless, when(如例句8), once, until, though/ although, even if/ even though, as(如例句9), as if等。【难点点拨】此结构实际是状语从句的省略形式。当状语从句的主语与主句的主语一致，且状语从句的谓语动词是被动式时，省略从句的主语和动词be即是。 Water can be changed into vapor when (it is) heated. There is no point arguing about it, just do as (you are) told. 四、过去分词的独立主格结构作状语如果过去分词的逻辑主语与句子的主语不一致，这种带逻辑主语的过去分词结构属于独立主格结构，作状语，表示时间、原因、条件、方式、伴随等(如例句10)。

现在分词作状语

分词短语V-ing 形式与V-ed形式作状语用法比较一、V-ing 形式与V-ed形式是非谓语动词的一种，在句法功能上主要起形容词或副词作用，在句中可作除谓语之外的所有成份。其中最难的一种是作状语的用法，相当于副词用法，用句子结构中，V-ing 形式与V-ed形式可以表时间、条件、原因、伴随、方式、让步等。例句： 1、Walking in the street, he met an old friend. 2、Having a lot of things to do, I can’t go swimming with you. 3、Turning right and covering another two blocks, you will get to your destination. 4、He came here, running and singing. 5、Asking around, I find many people willing to pay slightly higher prices for things that are environmentally friendly. 6、Seen from the top of the hill ,the city looked like a big garden. 7、Deeply moved by the story ,the excited people stopped quarrelling with each other. 8、Given another chance ,he will do better. 9、Laughed at by many people ,he continued his study. 二、V-ing 形式与V-ed形式结构及用法(三原则) 1)：逻辑主语一致原则。V-ing 形式与V-ed形式首先遵循逻辑主语一致的规律，即主、从句共主语 2)、且看构成主主谓还是动宾的原则。如果逻辑主语与谓语动词构成主动关系，使用V-ing 形式；如果逻辑主语与谓语动词构成被动关系，使用V-ed形式 3)、且看有没有时间先后的原则四种情况： 1、没有时间先后，如果构成的是主动关系：则使用V-ing的一般式 2、有时间先后，如果构成的是主动关系：则使用having done的形式。 3、没有时间先后，如果构成的是被动关系：则使用V-ed形式的一般式 4、有时间先后，如果构成的是被动关系：则使用having been done的形式。注意： V-ing 形式与V-ed形式的否定式是在分词前面加not. 三、练习讲解 1、he sat there, what to do.(not know) 2、by him, we worked even harder.(inspire) 3、carefully to you two, I am surprised that you agree with each other.(listen) 4、of danger in the street at night ,she had to go home, with a friend following her.(warn)
