动名词作表语,主要是对主语内容的进一步说明和解释。它和主语间可以划等号,甚至可以交换位置。例如: Her job is looking after children.(她的工作就是照看小孩)可以换为:Looking after children is her job.(照看小孩就是她的工作) The problem is finding land for it.(问题是要为它找到土地)可以换为:Fanding land for it is the problem.(为它找到土地,这是个问题) 而现在分词充当表语,主要对主语特征进行描述,不能同主语划等号,因此不能同主语换位置。例如: The situation was puzzling. 形势令人迷惑不解。 Her speech was touching. 她的发言很感人。 |
