单凭一个词 knowing, 永不能判断是动名词或现在分词。原因这正是断章取意 !所以,必须把 knowing放入句中判决,才是正确踏实。举些例子 :The mouse ran knowing the danger in front.knowing是动名词。Knowing the thunderstorm, I shut off the windows.Knowing是分词。Knowing that advice, I 'll win the game.Knowing是分词短语。Participial Phrase.[意思是 : If I know the advice, I will win the game. ]
