什么叫分詞的邏輯主語

分詞屬非謂語動(dòng)詞，即不用作謂語的動(dòng)詞，所以它沒有真正的主語。但是，分詞作為動(dòng)詞的一種形式，它應(yīng)有自己理論上或邏輯上的主語。如：

I often hear him singing this song. 我經(jīng)常聽他唱這首歌。(him 是singing的邏輯主語)

Hearing the news, he couldn't help crying. 聽到這消息，他禁不住哭了。(he是hearing的邏輯主語)

若用的是過去分詞或現(xiàn)在分詞的被動(dòng)式，則上面提到的邏輯主語實(shí)為“邏輯賓語”：

I often hear this song sung. 我經(jīng)常聽到有人唱這首歌。(this song是sung的邏輯主語，但是sing 的邏輯賓語)

I saw her being taken to the operating room. 我看見她被送到手術(shù)室。(her是being taken 的邏輯主語，但是take 的邏輯賓語)

分詞作狀語，它的邏輯主語通常應(yīng)是句子主語，否則會(huì)出錯(cuò)。請看下例：

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

此題答案應(yīng)選D，因?yàn)榫涫子米鳡钫Z的現(xiàn)在分詞短語finding her car stolen 的邏輯主語應(yīng)是“她”，而不是 a policeman, the area, it 等。
