问一下关于现在进行时的用法
Returning home late,my friend learned that the police had been to the flats
Note that the subject of the participle phrase is also the subject of the main clause in the sentence.
这句话是什么意思，这个用法我不太清楚，能不能讲的具体一点。
present participle phrase can also show two actions happening at the same time
I walked home,feeling sorry for the boy
为什么是WALK加ED，FEEL加ED不行吗，这个用法也请解释一下，谢谢
