Nobody having any more to say, the meeting was closed. 1 ．独立主格结构的形式： （ 1 ）名词 / 代词 + -ing 分词及其短语 The moon appearing, they decided to go on with their journey.The pupils are walking slowly, their teacher following. （ 2 ）名词 / 代词 + -ed 分词及其短语 Good-bye said, we went home.All things considered, it is a good plan. （ 3 ）名词 / 代词 + 形容词及其短语 The weather (being) hot, we all went swimming.Dinner ready, the hostess asked her guests to be seated. （ 4 ）名词 / 代词 + 不定式及其短语 The money to be paid by the driver, the police went away.Here are the first two volumes, the third one to come out next month. （ 5 ）名词 / 代词 + 副词及其短语 The meeting (being) over, we left the room. （ 6 ）名词 / 代词 + 介词及其短语 She stood there, book in hand.Everybody at home, we sat down to dinner . 2 ． with + 复合宾语结构 这种结构也可以看成是一种独立主格结构。这种结构有较鲜明的特色。在这种结构中， with 后的宾语相当于该结构中的逻辑主语，其后面的词相当于这个结构中的逻辑谓语。这个结构很像一个用来说明附带情况或细节的，可以起状语作用的句子。翻译时， with 原有的含意往往不翻译出来。 （ 1 ） with + 名词 / 代词 + 名词 The brave man fought the tiger with a stick his only weapon.He was carried into the hospital, with his face a mass of bleeding flesh. （ 2 ） with + 名词 / 代词 + 介词 The teacher came into the classroom with a book in his hand.He was asleep with his head on his arms.Family dependants, when ill, enjoy free medical treatment, with medicines at half price. （ 3 ） with + 名词 / 代词 + 副词 He went out with his hat on.The square looks more beautiful than ever with her lights on. 4 ） with + 名词 / 代词 + 形容词 Don’t speak with your mouth full.The once lowly serfs now walk with heads high. 5 ） with + 名词 / 代词 + -ing 分词 With the old man leading, the two started toward the mountains.With everyone surrounding us we can certainly succeed.She felt very nervous with so many people looking at her. （ 6 ） with + 名词 / 代词 + -en 分词 All the afternoon he worked with the door locked.He died with his life’s work still unfinished.With his matter settled, we left the room. （ 7 ） with + 名词 / 代词 + 不定式 They are highly mechanized farms, with machinery to do most of the work.This was a severe test, with innumerable difficulties to be overcome.With five minutes to go before the last train left, we arrived here. 3. 由 There being + 主语 这种结构多表示原因。例如： There being a lot of books to read , he often studied till midnight. 因为有许多书要读，他经常学习到深夜。 不定式与动名词作主语的区别： 不定式作主语时经常表示具体动作，而动名词作主语时经常表示抽象动作： It’s no good eating too much fat. It’s not good for you to eat so much fat. 关于逻辑主语的问题动名词复合结构的一般规则是： 1. 逻辑主语是有生命的名词：作主语时，须用名词所有格或形容词性物主代词；作宾语时，也可用普通格或人称代词宾格。 Tom’s (His) coming is what we have expe 2. 逻辑主语是无生命的名词： Is there any hope of our team winning the match She didn’t mind Jack/ Jack’s (him/ his) coming here. 1. ______to the meeting surprised all of the boards.
