范与规
现在分词短语做状语
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.
状语从句与分词作状语的转换
[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
4后置定语与定语从句
后置定语与定语从句 英语中的后置定语往往可以分为以下几类，形容词做后置定语，现在分词做后置定语，过去分词做后置定语，不定式作后置定语。而后置定语往往可以由定语从句演变而来，这种定语从句的关系词往往是关系代词在从句中充当主语。下面我们来逐一讨论： 1.现在分词作后置定语 ⑴Who is the girl dancing with your brother？（现在分词作后置定语， 表正在）可改写成定语从句Who is the girl that is dancing with your brother？ The high building being built (=which is being built)there is meant for the old without children. It is expected to be finished in a year.(正在被建) ⑵Anyone touching the wire will get a shock.可以改成定语从句Anyone who touches the wire will get a shock. 2.过去分词做后置定语 The jewelry (which is) worn by the Indians was made of bones. The spaceship (which was) called Shenzhou Ⅴ, was carrying China’s first astronaut, Yang Liwei. The Indians wearing (=who wore)jewelry (which was) made of bones greeted them warmly. 3.不定时作后置定语 表示未发生或即将发生的情况如 The project （which is）to be completed next month needs more people to help.（即将完成的） There are more pains (which are)to come.(要来的) Children who lived closest to the Fukushima-1 Nuclear Power Station were among the first to be tested.（the first，the last之后常用不定式作定语）

分词作后置定语40838
所谓“定语”，就是能起到修饰、限定、解释说明作用的语言，例如，形容词是定语，定语从句也是定语。由于一些分词或分词短语置于被修饰对象的后面，所以称作“后置定语”。 现在分词和过去分词都可以做后置定语。 （1）被修饰的名词与作定语的动词为主动关系，表示该动作正在进行或与主句动作同时发生，或是经常发生的行为时，用现在分词做定语。例如： The girl standing there is my sister. 站在那里的女孩是我姐姐。 The people waiting for the bus are talking with each other. 正在等公车的人们在相互交谈。 注意；分词短语作后置定语时可以改写成定语从句。 The girl who is standing there is my sister. The people who are waiting for the bus are talking with each other. （2）如果名词与作定语的动词为被动关系时，则定语有下列三种形式： a. 如果动作已发生或经常的行为，用done。 例如：The house built there is mine. 建在那儿的房子是我的。转为定语从句：The house which was built there is mine.
b. 如果动作正在进行，用being done。 例如：The house being built there is mine.正在那儿建造的房子是我的。 转为定语从句：The house which is being built there is mine. c. 如果动作未发生，用to be done。 例如：The house to be built there is mine.将要在那儿建起来的房子是我的。 转为定语从句：The house which is to be built there is mine.

定语从句与非谓语动词的转换
定语从句和非谓语动词是高中阶段重要的两大语法项目。定语从句的应用可以使语言表达更精确更生动，显得使用者具有较高的英语文化底蕴，但也是中学英语的难点语法项目，许多同学在学习和运用定语从句时，感到很难理解。若将其简化，理解起来就比较简单了。而非谓语动词的正确使用，就可以使定语从句的理解容易化，简单化，而且使语句简练、更有文采。掌握二者的转换，有助于我们更好的理解其用法，并能够自如地运用。下面我就着重谈谈如何将定语从句转换成非谓语动词以及转换时应注意的事项。 1定语从句转换成不定式“to do”。 定语从句的谓语动词是将来时或含有情态动词或含有序数词the next，the last等时，该定语从句转换为不定式“to do”. （1）The plane which will arrive is from Hubei. →The plane to arrive is from Hubei。 （2）The students will go to a party that will be held in our class at 7：45. →The students will go to a p arty to be held in our class at 7：45. （3）He was the first boy who came to school. →He was the first boy to come to school. .2定语从句可转换成为“介词+关系代词或副词+不定式”。“介词+关系代词”引导的定语从句和“介词+关系代词或副词+不定式”充当的定语，可以相互转换。被这种定语修饰的名词往往在逻辑上充当不定式动作的地点、时间或工具。例： （1）She wanted a room in which she could do her homework. →She wanted a room in which to do her homework. （2）She had only a pen with which she can write. →She had only a pen to write with.或She had only a pen with which to write. 注：定语从句转换成“介词+ 关系代词+不定式”时，此时的不定式一定是及物动词，如是不及物动词，则需在动词后面加上相应的介词。这个介词可提前到关系代词前面，也可留在句尾。前者是正式说法后者是非正式说法。而且上例中动词不定式与句子主语之间存在着逻辑上的主谓关系，否则就不能简单地把作定语的不定式都变成此结构。 “He is looking for a place for his friend to live in”这句话。我们就不能将句中的a place for his friend to live in改为a place to live in或a place in which to live。 3.1定语从句可以转换为现在分词（短语） 如果定语从句的谓语是主动语态，且发生的时间与主句的谓语所表示的动作所发生的时间同时，此时可以将定语从句转换成现在分词短语）。 （1）Have you ever talked to the girl who is dancing to music over there？→Have you ever talked to the girl dancing to music over there？ （2）The question that is being discussed is about how to improve living conditions. →The question being discussed is about how to improve living conditions. .2定语从句可以转化为过去分词（短语） 如定语从句的谓语是被动语态，或是“系动词+过去分词（表语）”结构，且从句的谓语动词所表示的动作或状态是在主句的谓语之前发生或无明确的时间。此时，我们可以将定语从句转换成过去分词（短语）。有时定语从句谓语虽然是主动语态.但它表示的动作在主句谓语之前就已经完成，这时我们可以将定语从句转换成过去分词（短语）。 （1）The report that was made yesterday will be discussed today. →The report made yesterday will be discussed today. （2）The dictionary which my mother bought for me is very useful.
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 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：
非谓语动词与从句的转换
高考写作一非谓语动词与从句的转换 知识讲解 知识点1：不定式（短语）与从句的关系 1.【考查点】：不定式（短语）在句中作主语，其功能相当于一个主语从句，因此二者之间可以转换。 (1).To be able to help you is really an honor. (=That I’m able to help you) (2).He seemed to know the way.

现在分词短语作状语
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.
