12、written in pencil are from my sister. All the letters in the drawer, written in pencil, are from my sister., 注意：现在分词短语作定语时，所表示的动作不能先于谓语所表示的动作，也不可以表示将来。另外，一般不用现在分词的完成式作定语，所以，下列句子都是错的： Those having finished their work can go home now. (应改为who have finished) The man giving us a lecture last week left f
