大學(xué)英語四級語法講解：獨立主格結(jié)構(gòu)

大學(xué)英語四級考試涉及的語法知識點多、涉及面寬。對不少考生來說都是一個難題，希望通過本節(jié)的學(xué)習(xí)，考生能對四級語法有更全面的掌握!

一 、獨立結(jié)構(gòu)的構(gòu)成：

只有當(dāng)分詞短語的邏輯主語和句子主語不一致時，我們才能用獨立結(jié)構(gòu)。獨立結(jié)構(gòu)只用做狀語，多用于書面語言。常見的獨立結(jié)構(gòu)有以下幾種：

(一) 名詞/代詞 分詞(包括現(xiàn)在分詞和過去分詞)：

1 The boy ran quickly, his father following. (表示伴隨情況)

2 He lay on his back, his hands acrossed under his head. (表示伴隨情況)

(二)名詞/代詞 形容詞：

1、They started home, their minds full of plans for increasing production. (表示伴隨情況)

2、 He was silent for a moment, his lips tight. (表示伴隨情況)

(三)名詞/代詞 副詞：

1、 He put on his socks, wrong side out. (表示補充說明)

2 、The war over, all the Chinese people’s volunteers came back to China. (表示補充說明)

(四)名詞/代詞 介詞(短語)

1 、She came in, a baby in her arms. (表示伴隨情況)

2 、He went off, gun in hand. (表示伴隨情況)

二、獨立結(jié)構(gòu)在句子中的作用：

獨立結(jié)構(gòu)在句子中只能做狀語，這種結(jié)構(gòu)可以用來：

(一)表示時間：

His homework done, Jim decided to go and see the play.

(=After his homework was done, he decided to go and see the play.)

(二)表示原因：

The last bus having gone, we had to walk home.

(=Because the last bus having gone, we had to walk home. )

(三)表示條件：

Weather permitting, we’ll go for an outing tomorrow.

(=If weather permitting, we’ll go for an outing tomorrow.)

(四)表示伴隨情況或伴隨狀況：

They walked through the forest, an old hunter leading the way.

(五)表示補充說明：

He lived in a wooden house with two rooms, one being a bedroom and the other being an office.

(=He lived in a wooden house with two rooms, one was a bedroom, the other was an office.)

三、獨立變格的變化

在帶有邏輯主語的分詞及其短語前加”with”

1、——Why are they taking all the equipment away?

——The job_____, they are packing up to leave.

A. it to done B. did C. was did D. done

2、Other things being equal, a man who expresses himself effectively is sure to succeed more rapidly than the man whose command of language is poor.
