分詞邏輯主語(yǔ)的不一致性與獨(dú)立主格結(jié)構(gòu)

在通常情況下，分詞作狀語(yǔ)時(shí)它的邏輯主語(yǔ)應(yīng)與句子主語(yǔ)一致，若不一致，則應(yīng)改用其他句型，如：

誤：Crossing the road, a car knocked him down.

正：Crossing the road, he was knocked down by a car. 過(guò)馬路時(shí)他被車撞倒了。

正：When he was crossing the road, a car knocked him down. 他過(guò)馬路時(shí)車子把他撞倒了。

解決狀語(yǔ)分詞的邏輯主語(yǔ)與句子主語(yǔ)不一致的問(wèn)題，也可在分詞前加一個(gè)名詞或代詞，使之成為分詞的邏輯主語(yǔ)。由于加在分詞前的名詞或代詞要用主格形式，故稱分詞的獨(dú)立主格結(jié)構(gòu)。如：

The test finished, we began our holiday. 考試結(jié)束了，我們開始放假。

Weather permitting, we are going to visit you tomorrow.　天氣允許，我們明天去看你。

The weather being fine, we went swimming. 天氣很好，我們就去游泳了。

He being absent, nothing couldn’t be done. 由于他缺席，什么事也干不成。
