　　獨(dú)立主格結(jié)構(gòu)

　　獨(dú)立主格結(jié)構(gòu)指帶主語的動(dòng)詞分詞、介詞、或副詞詞組。 何謂獨(dú)立主格結(jié)構(gòu)?

　　它是指與主語之間無任何語法關(guān)系的名詞或代詞加上一個(gè)分詞的結(jié)構(gòu)。它不修飾單個(gè)的詞，而修飾整個(gè)句子。獨(dú)立主格結(jié)構(gòu)可位于句子的任何部位。它構(gòu)成一個(gè)單獨(dú)實(shí)體，并具有如下兩種功能：(1) 解釋原因或情景 (2) 提供主句中重點(diǎn)部分的相關(guān)細(xì)節(jié)。

　　例 Freud distinguished three kinds of anxiety, each arising from a different source of perceived danger.

　　"each" 是獨(dú)立主格結(jié)構(gòu)，"arising from"是動(dòng)詞短語。注意這個(gè)獨(dú)立主格結(jié)構(gòu)是一個(gè)"干巴巴"的句子。通過改變動(dòng)詞形式，它的面貌可煥然一新：Each arises from a different source of perceived danger.

　　Better: In the end, defending Australian Open champion Petr Korda, the drug controversy around him still festering, walked away with a salute to a cheering crowd.

　　有些短語在語法上可與它所在句中的其它成分分離。這種結(jié)構(gòu)不修飾句子的任何一個(gè)詞，而修飾句子的整體意思。

　　分詞連同它所修飾的名詞或代詞可構(gòu)成獨(dú)立主格結(jié)構(gòu)。同位語和插入語有時(shí)也被認(rèn)為是獨(dú)立主格結(jié)構(gòu)
