动名词复合结构与独立主格结构
崔长平河南遂平一高（463100）
①动名词复合结构的一般构成：
1）名词的所有格形式＋动名词（或动名词短语）
2）形容词性的物主代词＋动名词（或动名词短语）
如不置于句首时，可以使用：名词＋动名词（或动名词短语）或者宾格代词＋动名词（或动名词短语）动名词复合结构主要在句中做主语、宾语或表语等。它能够侧重说明动名词所表示的动作的执行者。
Would you mind my/me closing the window? (比较：Would you mind closing the window?) Bob′s being absent made his teacher very angry.
No one will dream of there being such a famous place in the world.
Her having lost the keys made Mary very disappointed.
②独立主格结构具体构成形式如下：
⑴名词或主格代词＋现在分词（或现在分词短语）
等的变化，要结合具体句意，使用不同的形式。）
e.g. Spring coming on，the trees turned green. It being Sunday，the library was closed.
There being no buses，we had to walk home.（there being 是there be 句型的独立主格结构。） Our work （having been） finished，we went home hurriedly.
The key （having been ）lost，she could not enter the room.
Weather permitting，we will go picnicking by the waterfall.
It being fine，we will go climbing in the afternoon.
Time permitting，we will go for an outing.
⑵名词或主格代词＋过去分词（或过去分词短语）
（独立主格结构中呈现逻辑上的被动的主谓关系。过去分词体现被动或完成意义。）
e.g. He lay on his back，his teeth set，his right hand clenched on his breast，and his glaring
eyes looking straight upward.
Her wallet stolen，she had no money to buy even a bus ticket.
The signal given，the bus started.
⑶名词或主格代词＋动词不定式（或动词不定式短语）
也要结合具体句意，使用不同的形式。）
e.g. Here are the first two volumes，the third one to come out next month.
⑷名词或主格代词＋形容词（短语）或副词（短语）
e.g. He entered the room，his nose red with cold. Betty put on her socks wrong side out.
⑸名词或主格代词＋介词短语
，sword in hand.
In front of the house was a tall tree，its top well above the tops of the other trees. ▲独立主格结构经常在句中作状语。（注意，独立主格结构只是一种结构，不是句子，因此，它与句子的主干之间一般只用逗号隔开，而不能加用诸如and ,but ,so之类的连接词。）
1.原因状语：e.g. The teacher being ill，the lecture was put off.
There being nothing to do，we went home.
2.时间状语：e.g. The guest having left，they went on with their discussion.

5种基本句型和独立主格结构讲解
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。
高中英语独立主格结构详细讲解
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。

独立主格结构图表解析
独立主格结构 一、概念 “独立主格结构”就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成分。该结构不是句子，也不是从句，所以它内部的动词不能考虑其时态、人称和数的变化，它与主句之间不能通过并列连词连接，也不能由从句阴道词引导，通常用逗号与主句隔开。独立主格结构在很多情况下可以转化为相应的状语从句或者其他状语形式，但很多时候不能转化为分词形式，因为它内部动词的逻辑主语与主句主语不一致。 二、独立主格的特点
1.当独立主格结构中的being done表示“正在被做时”，being不可以被省略。 2.当独立主格结构的逻辑主语是it, there时，being不可以省略。 三、独立主格结构的用法。 一般放在句首，表示原因时还可放在句末；表伴随状况或补充说明时，相当于一个并列句，通常放于句末。
四、非谓语动词独立主格结构。 “名词或代词+非谓语动词”结构构成的独立主格结构称为非谓语动词的独立主格结构。名词或代词和非谓语动词具有逻辑上的主谓关系。 1.不定式构成的独立主格结构 不定式构成的独立主格结构往往表示还未发生的行为或状态，在句中常 作原因状语，有时做条件状语。 Lots of homework to do, I have to stay home all day. 由于很多作业要做，我只好待在家里。 So many children to look after, the mother has to quit her job. 如此多的孩子要照顾，这个妈妈不得不辞掉她的工作。 2.动词+ing形式的独立主格结构 动词-ing形式的句中作状语时，其逻辑主语必须是主句的主语，否则就 是不正确的。动词-ing形式的逻辑主语与主句的主语不一致时，就应在 动词的-ing形式前加上逻辑主语，构成动词-ing 形式的独立主格结构，逻辑主语与动词间为主谓关系，是分词的动作执行者，分词表示的动作 时逻辑主语发出的动作。 We redoubled our efforts, each man working like two. 我们加倍努力，每个人就像在干两个人的活。 The governor considering the matter, more strikers gathered across his path. 总督思考这个问题时，更多的罢工工人聚集到他要通过的路上。 The guide leading the way, we had no trouble getting out of the forest. 在向导的带领下，我们轻松地走出了森林。 3.过去分词形式的独立主格 过去分词形式的独立主格结构是由“逻辑主语+过去分词”构成。逻辑主 语与动词之间为动宾关系，它是分词的动作承受者，这一结构在句中作 时间状语，原因状语、伴随状语、条件状语等。 This done, we went home.做完这个，我们就回家了。 All our savings gone, we started looking for jobs. 积蓄用完后，我们都开始找工作。 More time and money given, we can finish the work in advance. 如果给予更多的时间和金钱，我们能提前完成这个工作。 五、其他形式的独立主格结构

分词作状语： 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.) Heated,ice will be changed into water.(=When it is heated...) Being excited, I couldn’t go to sleep.(=As I was excited,I couldn’t go to sleep.) I stood there, listening to the broadcast.(=I stood there and listened to the broadcast.) The children went away laughing.(=The children went away.They laughed as they went.) Knowing all this,they made me pay for the damage.(=Although they know all this... (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. Not knowing what to do, he went to his parents for help. 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. F aced with difficulties,we must try to overcome them. (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. While walking along the street early in the morning,he saw her. 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. Even though given every opportunity,they would not try. Though knowing the truth,he remained silent. Unless (being) rich,I am not going abroad. (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. The boys returned,their face covered with sweat. 〈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.
