            2019年6月大學(xué)英語四級(jí)重點(diǎn)語法知識(shí)盤點(diǎn)
            英語四級(jí)重點(diǎn)語法知識(shí)：獨(dú)立主格結(jié)構(gòu)
            一 、獨(dú)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(shí)，我們才能用獨(dú)立結(jié)構(gòu)。獨(dú)立結(jié)構(gòu)只用做狀語，多用于書面語言。常見的獨(dú)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(bǔ)充說明)
            2 、The war over, all the Chinese people’s volunteers came back to China. (表示補(bǔ)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(dú)立結(jié)構(gòu)在句子中的作用：
            獨(dú)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(shí)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(bǔ)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(dú)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.
