请问为什么选seen不选seeing?
seeing these pictures,I couldn’t help thinking of those days when I was in Being and 【seen】【seeing】 from the top of a thirty-storeyed building,Beijing looks more beautiful
请问see在句中是什么成分?它的逻辑主语在哪?

Answer 1

分词词组作状语时,分词的逻辑主语须与主句主语一致.
在Seeing these pictures,I couldn’t help thinking of those days when I was in Beiijng .中,seeing的逻辑主语就是I, 当然I 为see的发出者,故现在分词表示主动.Seeing these pictures=When I saw these pictures.
而 Seen from the top of a thirty-storeyed building,Beijing looks more beautiful.根据规则,seen的逻辑主语就是Beijing, 故是被看的,过去分词表被动.Seen from the top of a thirty-storeyed building =When Beijing is seen from .
