什么叫分词的逻辑主语

什么叫分词的逻辑主语

分词属非谓语动词，即不用作谓语的动词，所以它没有真正的主语。但是，分词作为动词的一种形式，它应有自己理论上或逻辑上的主语。如：

I often hear him singing this song. 我经常听他唱这首歌。(him 是singing的逻辑主语)

Hearing the news, he couldn't help crying. 听到这消息，他禁不住哭了。(he是hearing的逻辑主语)

若用的是过去分词或现在分词的被动式，则上面提到的逻辑主语实为“逻辑宾语”：

I often hear this song sung. 我经常听到有人唱这首歌。(this song是sung的逻辑主语，但是sing 的逻辑宾语)

I saw her being taken to the operating room. 我看见她被送到手术室。(her是being taken 的逻辑主语，但是take 的逻辑宾语)

分词作状语，它的逻辑主语通常应是句子主语，否则会出错。请看下例：

1. Finding her car stolen, ________.

A. a policeman was asked to help

B. the area was searched thoroughly

C. it was looked for everywhere

D. she hurried to a policeman for help

此题答案应选D，因为句首用作状语的现在分词短语finding her car stolen 的逻辑主语应是“她”，而不是 a policeman, the area, it 等。
