1、独立主格结构非谓语动词作状语时，它的逻辑主语应该是句子的主语。但有时非谓语动词带有自己的主语，从而在结构上与主语不发生关系，我们称之为独立主格结构（Absolute Construction）。其实，所谓“独立主格结构”也并非真正独立，它还是一种从属的结构。一、非谓语动词独立主格结构在独立主格结构中，非谓语动词和它前面的名词或代词存在着逻辑上的主谓关系。 Such an able man to help you，you will surely succeed sooner or later. 有这么能干的人来帮你, 你迟早一定会成功的。（such an able man和 to help yo
2、u 之间存在着主谓关系） = Since such an able man will help you, you will surely succeed sooner or later. He seating himself at the desk, his mother began to tell him a story. 他在书桌旁坐好后，他母亲开始给他讲故事。（seating himself at the desk拥有了自己的逻辑主语he，注意是“主格”） = When he seated himself at the desk, his mother began to tell him
3、 a story. The key to the bike lost, he had to walk to school. 由于丢了自行车钥匙，他只好步行去学校。（lost 的逻辑主语是the key，lost 也可以用完成式having been lost） = Because the key to the bike had been lost, he had to walk to school.A不定式“独立主格结构”在“逻辑主语+动词不定式”结构中，动词不定式和它前面的名词或代词存在着逻辑上的主谓关系。这种结构也可用一个从句或并列分句来表达。1动词不定式用主动的形式 在独立主格结构中，动
4、词不定式和它前面的名词或代词存在着逻辑上的主谓关系。 His mother to come tonight，he is busy preparing the dinner. 他母亲今晚要来,他正在忙着准备饭菜。（= As his mother is to come tonight, he is busy preparing the dinner.） will you go to the comcert tonight 你今晚去听音乐会吗？ sorry.So many exerise-books to check,I rially cant afford any time. 对不起，有这多的作业

6、ok.） Many trees,flowers,and grass to be planted,our newly-built school will look even more beautiful. 种上许多的树，花和草后，我们新建的学校将看上去更美。(=If many trees,flowers,and grass are planted,our newly-built school will look even more beautiful.)B-ing形式“独立主格结构”动词的-ing形式作状语时，其逻辑主语一般应与句子的主语保持一致。 Being ill, he went home
7、. 由于生病,他回家了。（= As he was very ill, he went home.） Seating himself at the desk, he began to read a magazine.在课桌旁坐好后，他开始看杂志。（= When he had seated himself at the desk, he began to read a magazine.） 1 表示时间的-ing形式作“独立主格结构” Everyone being ready, the teacher began his class. 每个人都准备好后，老师开始上课。（相当于一个时间状语从句Whe
8、n everyone was ready) The chairman began the meeting , everyone being seated. 每个人坐好后，主席开始开会。（相当于一个时间状语从句after everyone was seated） 2 表示原因的-ing形式作“独立主格结构” The boy leading the way, we had no trouble finding the strange cave. 由那个男孩带路，我们没有困难就找到了那奇怪的洞。（相当于一个原因状语从句Because the boy led the way） Many eyes wa
9、tching him, he felt a bit nervous. 许多眼睛看着他，他感到有点儿紧张。（相当于一个原因状语从句As many eyes were watching him） 必背： 含有being的独立主格结构。 It being National Day today，the streets are very crowded. 今天是国庆节,街上很拥挤。 = As it is National Day today, the streets are very crowded. There being no further business to discuss, we all
10、went home. 没有别的事可讨论，我们都回家了。 = As there was no further business to discuss, we all went home. 3 表示条件的-ing形式作“独立主格结构” Time permitting, we will have a picnic next week. 时间允许的话，我们下星期将进行一次野炊。（相当于一个条件状语从句If time permits) My health allowing, I will work far into the night. 我的健康许可的话，我愿工作到深夜。（相当于一个条件状语从句If m
11、y health allows） 4 表示方式的-ing形式作“独立主格结构” The students are walking in the school happily, each wearing a card in front of his chest. 学生们快乐地在学校里走着，每个人胸前都带着一张卡。（相当于一个并列分句and each wears a card in front of his chest） The boy lay on the grass, his eyes looking at the sky. 男孩躺在草地上，眼睛看着天空。（相当于一个并列分句and his e
12、yes were looking at the sky）C-ed形式“独立主格结构” 与逻辑主语+动词的-ing形式一样，如果-ed形式的逻辑主语和句子的主语不一致的话，就需要用-ed形式的独立主格结构。 The book written in simple English, English beginners were able to read it. 该书是用简单英语写的，英语初学者也能看懂。 = As the book was written in simple English，English beginners were able to read it. The workers wor
13、ked still harder, their living conditions greatly improved. 由于工人们的生活条件大大提高，他们工作得更起劲了。 = As their living conditions were greatly improved, the workers worked still harder.

14、, and his eyes were fixed on the blackboard. The task completed,he had two months leave. 任务完成以后，他休了两个月的假。（=When the task had been completed,he had two months leave.） 比较： 动词不定式表示动作没有发生或即将发生，动词-ed形式表示动作已经结束，动词-ing形式往往表示动作正在进行。 The manager looks worried，many things to settle. 经理看上去很着急, 有这么多的事情要处理。（事情还没
15、有处理，而且是由经理本人来处理，用不定式to settle） The manager looks relaxed, many things settled. 许多事情已经处理好了， 经理看上去很轻松。（事情已经处理好了，用动词-ed形式settled表示动作已经结束） The food being cooked, the boy was watching TV. 小孩一边做饭，一边看电视。（两个动作同时进行） The food cooked, the boy went to bed. 饭做好了，小孩去睡了。（两个动作有先后，饭已做好，小孩才去睡觉的）二、动词独立主格结构“逻辑主语+being+
16、其他”是独立主格结构中的“逻辑主语+动词-ing形式”的一种形式。在这种结构中，being往往可以被省去，这种省去being的结构，称之为无动词“独立主格结构”。A逻辑主语+名词 Ten students entered for the competition, the youngest a boy of 12. 十个学生报名参加了这次竞赛，年纪最小的是个12岁的男孩。（the youngest和a boy of 12之间省去了being） 注意： 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，二是在逻辑主语是代词的情况下。 Ther
