新概念英語第三冊語法總結(jié)：獨立主格結(jié)構(gòu)

此獨立形式只是一個小短語，而不是主謂完整的簡單句，又稱之為獨立分詞構(gòu)句。當(dāng)分詞意義上的主語不是主句的主語時，必須在分詞前保留意義上的主語，否則語意不通。示例：

Being ill in bed, I can't go to school.

Mother being ill in bed, I can't go to school.1. 獨立主結(jié)構(gòu)形式可用以表時間，理由，條件，伴隨狀態(tài)等。He lay on the grass, the sun shining upon him.

= He lay on the grass, and the sun was shining upon him.Weather permitting, I'll start tomorrow.

= If weather permits, I'll start tomorrow.School being over, the boys went home.

= When school was over, the boys went home.The sun having set, we arrived at the station.

= After the sun had set, we arrived at the station.王牌重點：當(dāng)獨立主格結(jié)構(gòu)的主語表示“一般人”，如：we, one, you時，主語可省略，此用法常用于下列表達方式中：

generally speaking 一般來說

strictly speaking 嚴格地說

talking of ... 談到

speaking of ... 說到

judging from ... 由……來判斷

taking all things into consideration 把一切都考慮在內(nèi)

considering ... 考慮到……[示例]

If we judge from his face, he must be ill.

= Judging from his face, he must be ill.He has lots of books if we consider that he is young.

= He has lots of books, considering that he is young.2.with 復(fù)合結(jié)構(gòu)也是獨立主格結(jié)構(gòu)形式之一。這種結(jié)構(gòu)在句中作狀語(表示原因，方式，伴隨等)和定語，作定語時緊隨被修飾名詞后。(1) with+ 名詞 + 介詞短語
