英语中的独立主格结构 独立主格结构是由一个相当于主语的名词或代词加上非谓语动词、形容词、副词或介词短语构成的一种独立主格成分。With( without) 的复合结构可看作是独立主格结构的一种形式。 一、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。 The test finished, we began our holiday. = When the test was finished, we began our holiday. 4）当表示人体部位的词做逻辑主语时，及物动词用现在分词，不及物动词用过去分词 二、独立主格结构的构成: 名词普通格或代词主格+ 现在分词/过去分词/不定式/名词/形容词/副词/介词短语。 1．名词（或代词）+ 现在分词 现在分词表示前面的名词或代词主动进行的动作或状态。 He seating himself at the desk, his mother began to tell him a story. Everyone being ready, the teacher began his class. The food being cooked, the boy was watching TV. 注意：现在分词being或having been在独立主格结构中可以省略。 The weather（being）fine, we decided to go on an outing. 独立主格结构中的being在下列两种情况下一般不能省略， 一是在“There being + 名词”结构中，There being no bus, we had to walk home. 二是在逻辑主语是代词的情况下。It being Sunday, all the offices are closed. 2．名词（或代词）+ 不定式（短语）不定式表示将来的动作。 He suggested going for a picnic, Mary to provide the food. Many flowers and grass to be planted, our newly-built school will look even more beautiful. 3．名词（或代词）+ 过去分词 过去分词表示前面的名词或代词被动完成的动作。 The girls lay on her back, her hands crossed under her head. The workers worked still harder, their living conditions greatly improved. He was listening attentively in class, his eyes fixed on the blackboard. 4．名词（或代词）+ 形容词（短语） 形容词（短语）在独立主格结构中说明前面名词或代词的性质、状态 The floor wet, we had to stay outside for a while. He turned to me, his eyes sleepy. 5．名词（或代词）+ 副词 副词在独立主格结构中也多是说明名词或代词的状态。 The meeting over, we all went home. School over, we all went home. 6．名词（或代词）+ 介词短语 A robber burst into the room, knife in hand. He left the office, tears in eyes. 注意：在“逻辑主语+介词短语”构成的独立主格结构里，当介词是in时，其前后的两个名词均不加任何修饰成分。但with 的复合结构不受此限制。例如：The teacher came in, with a book in his hand.

独立主格结构 独立主格结构（ Independent Genitive）有两部分组成，前一部份是名词或者代词，后一部分是非谓语动 词(不定式、动名词和分词 )或形容词、副词、或介词短语。前后两部分具有逻辑主谓关系。独立主格结构在句中做状语，多用于书面语。独立主格结构本身不是句子，在句子中作状语，表示时间、原因、条件、伴随、目的等。 详细概述 非谓语动词作状语，其逻辑主语须与主句主语保持一致。若不一致，非谓语动词形式须另带主 语，从而构成复合结构的形式作状语。这种结构称为“独立结构”。其中，非谓语动词主动用V-ing ， 被动用 V-ed 。 非谓语动词及其短语前面带有逻辑主语，逻辑主语的代词又是主格，故常称为“独立主格”。独“ 立结构”在句中起状语作用，相当于状语从句，表示时间、原因、条件、方式或伴随等情况。 功能 独立主格结构主要用于描绘性文字中，其作用相当于一个状语从句，常用来表示时间、原因、 条件、行为方式或伴随情况等。例如： 表示时间 The meeting being over, all of us went home.开完会后我们都回家了。 Her work done , she sat down for a cup of tea.她干完了活，坐下来喝茶。 表示条件
The condition being favourable, he may succeed.若条件有利，他或许能成功。 表示原因 There being no taxes, we had to walk.没有出租车，我们只好步行。 He wrapped her up with great care,the night being dark and frosty. 夜又黑又冷，所以他把她裹得严严实实的。 表示伴随情况 Almost all metals are good conductors,silver being the best of all. 几乎所有的金属都是良导体，而银则是最好的导体。(=Almost all metals are good conductors, and silver is the best of all.) 用法 独立主格结构主要表示谓语动词发生的时间、原因、条件或伴随情况等，相当于一个状语从句或并列句。 用作时间状语 The work done (=After the work had been done), we went home.工作完成后，我们就回家了。 用作条件状语 Weather permitting(=If weather permits), they will go on an outing to the beach tomorrow. 如果天气允许的话，他们将在明天组织一次海滨小游。
一、 独立主格结构是一个名词或代词（作为逻辑主语），加上一个形容词、副词、介词短语、分词、不定式等在句中作状语。它有以下三个特点： (1)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形容词、副词、介词短语、分词、不定式等存在逻辑上的主谓关系。 (3)独立主格结构一般用逗号与主句分开，但与主句之间不能使用任何连接词。 二、 英语中，的形式是：名词或代词跟形容词、副词、介词短语、非谓语动词连在一起，构成。 1.名词/ 代词+ 不定式。如： A house to be built, we must save every cent. 由于要建一座房子，我们必须节省每一分钱。 Now here is Li Lei, Wei Fang to come tomorrow. 现在李蕾来了，魏方明天到。 2.名词/ 代词+ -ing分词。如： The bus coming here soon, we should get everything ready. 汽车很快就要来了，我们应该把一切事情准备好。 Mother being ill, Li Lei was very worried. 母亲病了，李蕾非常焦急。 3.名词/ 代词+ 动词的过去分词。如： His cup broken, he used his bowl instead. 茶杯破了，他就用碗来代替。 4.名词/ 代词+ 形容词。如： The ground muddy, we should be careful. 地面泞泥，我们应该小心。 5.名词/ 代词+ 副词。如： The class over, we all went out to play. 下课后，我们都出去玩。 6.

独立主格结构的用法说明与注意点 一、有关独立主格结构的基本概念 独立主格结构是一个名词或代词（作为逻辑主语），加上一个形容词、副词、介词短语、分词、不定式等在句中作状语。它有以下三个特点： 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形容词、副词、介词短语、分词、不定式等存在逻辑上的主谓关系。 3. 独立主格结构一般用逗号与主句分开，但与主句之间不能使用任何连接词。 二、独立主格结构的常见形式 独立主格类型1：名词（代词）+现在分词 The question being settled, we went home. 问题解决之后，我们就回家了。 We shall play the match tomorrow, weather permitting. 明天假设天气好，我们就进行比赛。 The monitor being ill, we’d better put the meeting off. 班长病了，我们最好还是延期开会吧。 独立主格类型2：名词（代词）+过去分词 The job finished, we went home. 工作结束后我们就回家了。 The last bus having gone, we had to walk home. 最后一班公车已经走了，我们必须走路回家。 More time given, we should have done the job much better. 如果给我们更多的时间，我们会把工作做得更好。 独立主格类型3：名词（代词）+不定式 Nobody to come tomorrow, we will have to put off the meeting till next week. 如果明天没有人来，我们将把会议推迟到下周。 So many people to help him, he is sure to succeed. 有如此多的人来帮助他，他一定会成功的。 独立主格类型4：名词（代词）+介词短语 The soldiers dashed in, rifle in hand. 士兵们端着枪冲了进来。 A girl came in, book in hand. 一个少女进来了，手里拿着书。 He was waiting, his eyes on her back. 他在等着，眼睛望着她的背影。 独立主格类型5：名词（代词）+形容词或副词 He sat in the front row, his mouth half open. 他坐在前排，嘴半开着。 She sat at the table, collar off, head down, and pen in position, ready to begin the long letter. 她坐在桌前，衣领已解掉，头低了下来，拿好钢笔，准备开始写一封长信。 独立主格类型6：There being +名词（代词） There being nothing else to do, we went home. 没有别的事可做，我们就回家了。 There being no further business, I declare the meeting closed. 没有再要讨论的事了，我宣布散会。 独立主格类型7：It being +名词（代词） It being Christmas, the government offices were closed. 由于圣诞节的缘故，政府机关都休息。 It being a holiday, all the shops were shut. 由于今天是假日，所有商店都关门了。 说明：独立主格结构有时可在其前加上介词with。如： Don’t sleep with the windows open. 别开着窗睡觉。 He stood before his teacher with his head down. 他低着头站在老师面前。 He was lying on the bed with all his clothes on. 他和衣躺在床上。 She came in with a book in her hand. 她手里拿着一本书走了进来。 He fell asleep with the lamp burning. 他没熄灯就睡着了。

英语：独立主格结构精讲精练 I. 独立主格结构的基本概念 由一个名词或代词作为逻辑主语,加上一个分词、形容词、副词、动词不定式或介词短语作为逻辑谓语构成,这种结构在形式上与主句没有关系,通常被称为独立主格结构。 II. 独立主格结构的基本构成形式及功能 独立主格结构主要起状语作用,相当于一个状语从句,多用来表示行为、方式、伴随等情况,有时也可用来表示时间、原因、条件等情况。 1、名词或代词主格+ 分词 ①The experiment done, the students went on to take notes in the experiment report. 实验做完了,同学们继续在实验报告上做记录。 ②Time permitting, we can have a walk around the playground after supper. 如果时间允许,晚饭后我们可以到操场上散散步。 2、名词或代词主格+ 形容词 ①Computers very small, we can use them widely. 电脑虽小,我们却能广泛地利用它们。 ② The clothes very dirty, you'd better wash them quickly. 衣服很脏,你快点儿洗洗吧! 3、名词或代词主格+ 不定式 The last guest to arrive, our party was started. 最后一位客人到了,我们的晚会就开始了。 4、名词或代词主格+ 介词短语 ① Our English teacher came into the classroom, papers in hand. 我们的英语老师走进了教室,手里拿着试卷。 ② There is a river in the valley, fresh flowers on the banks. 山谷中有一条河,河两岸长满了鲜花。 5、名词或代词主格+ 副词 ① The meeting over, our headmaster soon left the meeting-room. 散会了,校长很快就离开了会议室。 ② The lights off, we could not go on with the work. 灯熄了,我们不能继续工作了。 III. 独立主格结构及分词短语作状语的异同 1、独立主格结构与分词短语都可以转换为状语从句。但是,独立主格结构转换为状语从句后,它有自己的逻辑主语,与主句的主语不一致(例①)。而分词短语转换为状语从句后,从句的主语与主句的主语一致(例②)。 ① If time permits, we'd better have a holiday at weekends. 转换为: Time permitting, we'd better have a holiday at weekends. 如果时间允许,我们最好周末去度假。 ②When we see from the hilltop, we can find the city more beautiful.转换为: Seeing from the hilltop, we can find the city more beautiful. 从山顶上看,我们发现这个城市更美了。 2、还必须注意,分词结构的逻辑主语并不总是和主句的主语一致,也可以是主句的其它成分,语法上称作"依着法则"(例①)。而如果一个分词结构在句子中找不到它的逻辑主语,语法上称作"悬垂分词"(例②)。
独立主格 一、独立主格结构的含义和实质 “独立主格结构”（absolute construction）又叫“独立结构”，是带有自己主语的非谓语动词分句和无动词分句。由于在语法上有自己的逻辑主语，结构上与主句不发生关系，因此传统语法叫做“独立主格结构”。其实，所谓“独立主格结构”并非真正独立，它还是一种从属分句，与主句紧密联系在一起，共同表达一个完整的意思，通常在句中起状语分句的作用。独立主格结构可放于句首、句尾，用逗号和主句隔开。 二、独立主格结构的基本形式和功能 独立主格结构可以分为两部分：一部分是名词或代词，起逻辑主语的作用；另一部分是非谓语动词分句（现在分词、过去分词、不定式）或无动词分句（名词、形容词、副词、介词短语），表示前面名词或代词的动作或状态。 基本形式是：名词普通格/代词主格+现在分词/过去分词/不定式/名词/形容词/副词/介词短语，with引导的复合结构。 1．名词/代词+ 现在分词 现在分词表示前面的名词或代词主动进行的动作或状态等。 例The man lay there, his hands trembling. So many students being absent, the meeting had to be put off. His homework having been done, Tom went to sleep. 注：“独立结构”中的being或having been 有时可以省去，这样就成了无动词分句或过去分词分句。 2．名词/代词+过去分词 过去分词表示前面的名词或代词被动完成的动作或所处的一种状态。 例The boy lay on his back, his hands crossed under his head. The job not finished, we couldn’t see the film. Her shirt caught on a nail, she could not move. 后面两个句子也可以看成省略掉了having been，being。如果加上，这两个句子就又变成了现在分词分句。 3．名词/代词+不定式 不定式表示的是将来的动作。 例He suggested going for a picnic, Mary to provide the food. These are the first two books，the third one to come out next month. We shall get together at 7:30, the procession（游行）to start moving at 8 sharp. 4. 名词/代词+名词 名词一般做前面名词或代词的同位语。 例Many people joined in the work, some of them women and children. He fought the tiger，a stick his only weapon. 5．名词/代词+形容词短语 形容词（短语）说明前面名词或代词的性质，状态，原因等。 例The floor wet and slippery, we had to stay outside for a while. I heard that she got injured in the accident，my heart full of sorry. 这两个句子也可以看成是省略了being,如果加上，就变成了现在分词分句。 6．名词/代词+副词 副词说明前面名词或代词的状态。
独立主格结构小结 一．独立主格结构含义 独立主格结构，又叫独立结构（absolute construction）。它在句法上游离于句子主体之外，跟主句没有任何句法联系；但在意义上却与主句紧密联系在一起，共同构成一个完整的语义环境。独立主格结构没有主语和谓语，只有逻辑上的主语，因此，它在句法上不是句子，而是一个独立于句子成分之外的独特结构形式。 独立主格结构可置于句首、句尾，用逗号与主句隔开。 二、独立主格结构的形式 独立主格结构可分为两部分，一部分是名词或代词（主格），起着逻辑主语的作用；另一部分由形容词、副词、名词、分词、不定式、介词短语等构成，表示前面名词或代词的状态、状况或动作。 1）名词／代词＋形容词 I heard that she got injured in the accident，my heart full of worry． 我听说她在这场事故中受了伤，内心充满担忧。 He stood silent in the moon-light，his door open． 月光下，门开着，他默默地站立在那。 2）名词／代词＋现在分词 Winter coming，it gets colder and colder．冬天来了，天气越来越冷了。 The rain having stopped ，he went out for a walk．雨停了，他出去散步。 3）名词／代词＋过去分词 More time given，we should have done it much better． 如果给我们更多的时间，我们会做得更好。 The boy stood there，his right hand raised．那个男生站在那里，右手高举。 4）名词／代词（主格）＋不定式 Here are the first two volumes，the third one to come out next month． 这是前两卷，第三卷将于下月问世。 The two boys said good-bye to each other，one to go home，the other to go to his friend's．两个男孩彼此道了别，一个回了家，另一个去了他朋友家。 5）名词／代词十介词短语 The huntsman entered the forest，gun in hand．那位猎人手里提着枪走进了树林。 注意：这里，gun in hand还可以说成with a gun in his hand，但不可以说a gun in hand或gun in his hand。 6）名词／代词十副词 Nobody in，the thief took a lot of things away． 由于没有人，小偷拿走了许多东西。 Lunch over，he left the house．But he was thinking． 午饭结束，他离开屋。但他还在考虑。 7）名词／代词＋名词 He fought the wolf，a stick his only weapon． 他和狼搏斗着，唯一的武器是一根棍棒。 8）There being +名词（代词）如： There being nothing else to do, we went home. 没有别的事可做，我们就回家了。

独立主格结构 独立主格结构（Independent Genitive）有两部分组成，前一部份是或者代词，后一部分是非(不定式、动名词和)或形容词、、或介词短语。前后两部分具有逻辑主谓关系。独立主格结构在句中做状语，多用于书面语。独立主格结构本身不是句子，在句子中作状语，表示时间、原因、条件、伴随、目的等。 详细概述 非谓语动词作状语，其逻辑须与主句主语保持一致。若不一致，非谓语动词形式须另带主语，从而构成复合结构的形式作状语。这种结构称为“独立结构”。其中，非谓语动词主动用V-ing，被动用V-ed。 非谓语动词及其短语前面带有逻辑主语，逻辑主语的又是主格，故常称为“独立主格”。“独立结构”在句中起状语作用，相当于状语从句，表示时间、原因、条件、方式或伴随等情况。 功能 独立主格结构主要用于描绘性文字中，其作用相当于一个，常用来表示时间、原因、条件、行为方式或伴随情况等。例如： 表示时间 The meeting being over, all of us went home. 开完会后我们都回家了。 Her work done, she sat down for a cup of tea. 她干完了活，坐下来喝茶。 表示条件 The condition being favourable, he may succeed. 若条件有利，他或许能成功。 表示原因 There being no taxes, we had to walk. 没有出租车，我们只好步行。 He wrapped her up with great care, the night being dark and frosty. 夜又黑又冷，所以他把她裹得严严实实的。 表示伴随情况 Almost all metals are good conductors, silver being the best of all. 几乎所有的金属都是良导体，而银则是最好的导体。(=Almost all metals are good conductors, and silver is the best of all.) 用法 独立主格结构主要表示发生的时间、原因、条件或伴随情况等，相当于一个状语从句或并列句。 用作时间状语 The work done(=After the work had been done), we went home. 工作完成后，我们就回家了。
英语中的五种基本句型结构 一、句型1：Subject (主语) ＋Verb (谓语) 这种句型中的动词大多是不及物动词，所谓不及物动词，就是这种动词后不可以直接接宾语。常见的动词如：work, sing, swim, fish, jump, arrive, come, die, disappear, cry, happen等。如： 1) Li Ming works very hard.李明学习很努力。 2) The accident happened yesterday afternoon.事故是昨天下午发生的。 3）Spring is coming. 4) We have lived in the city for ten years. 二、句型2：Subject (主语) ＋Link. V(系动词) ＋Predicate(表语) 这种句型主要用来表示主语的特点、身份等。其系动词一般可分为下列两类： (1)表示状态。这样的词有：be, look, seem, smell, taste, sound, keep等。如： 1) This kind of food tastes delicious.这种食物吃起来很可口。 2) He looked worried just now.刚才他看上去有些焦急。 (2)表示变化。这类系动词有：become, turn, get, grow, go等。如： 1) Spring comes. It is getting warmer and warmer.春天到了，天气变得越来越暖和。 2) The tree has grown much taller than before.这棵树比以前长得高多了。 三、句型3：Subject(主语) ＋V erb (谓语) ＋Object (宾语) 这种句型中的动词一般为及物动词, 所谓及物动词，就是这种动词后可以直接接宾语，其宾语通常由名词、代词、动词不定式、动名词或从句等来充当。例： 1) He took his bag and left.（名词）他拿着书包离开了。 2) Li Lei always helps me when I have difficulties. (代词)当我遇到困难时，李雷总能给我帮助。 3) She plans to travel in the coming May Day.（不定式）她打算在即将到来的“五一”外出旅游。 4) I don’t know what I should do next. (从句)我不知道下一步该干什么。 注意：英语中的许多动词既是及物动词，又是不及物动词。 四、句型4：Subject(主语)＋Verb(谓语)＋Indirect object(间接宾语)＋Direct object (直接宾语) 这种句型中，直接宾语为主要宾语，表示动作是对谁做的或为谁做的，在句中不可或缺，常常由表示“物”的名词来充当；间接宾语也被称之为第二宾语，去掉之后，对整个句子的影响不大，多由指“人”的名词或代词承担。引导这类双宾语的常见动词有：buy, pass, lend, give, tell, teach, show, bring, send等。如： 1) Her father bought her a dictionary as a birthday present.她爸爸给她买了一本词典作为生日礼物。 2）The old man always tells the children stories about the heroes in the Long March. 老人经常给孩子们讲述长征途中那些英雄的故事。上述句子还可以表达为： 1）Her father bought a dictionary for her as a birthday present. 2）The old man always tells stories about the heroes to the children in the Long March. 五、句型5：Subject(主语)＋Verb (动词)＋Object (宾语)＋Complement(补语) 这种句型中的“宾语＋补语”统称为“复合宾语”。宾语补足语的主要作用或者是补充、说明宾语的特点、身份等；或者表示让宾语去完成的动作等。担任补语的常常是名词、形容词、副词、介词短语、分词、动词不定式等。如： 1）You should keep the room clean and tidy. 你应该让屋子保持干净整洁。（形容词） 2) We made him our monitor.(名词)我们选他当班长。 3) His father told him not to play in the street.(不定式)他父亲告诉他不要在街上玩。
