A 在英語中ing可表示伴隨狀態(tài)
ed是過分 通常表示過去或者被動
也可理解成是hear的用法如上一個人的回答
但官方的理解應該是 ing表伴隨
下面有我找的例子
She walked to school singing and smiling.
He had to work standing.
The old woman likes sitting there doing nothing.
My mother is sitting on the sofa watching TV
但也有特殊情況
with+名詞+動詞ing 表示主動
with+名詞+動詞ed 表示被動
主動還是被動關鍵是看with后的這個名詞是否能執(zhí)行該動作,能做就是主動,不能做就是被動.
例如：I left the house with all the lights turned off.燈與關的關系只能是被動,所以用ed形式.
I left the house with my sister watchng TV.sister與watch的關系是主動,所以用ing形式.
