(=He opened the drawer and took out his wallet.) 他打开抽屉，拿出钱包。,Coming into the room, he put down his bag. (=He came into the room and put down his bag.) 他走进房间，放下提包。,Having brushed his teeth, Mr. Brown came downstairs for breakfast. 布朗先生刷过牙, 就下楼来吃早饭。 (此句如写成: Brushing his teeth, Mr. Brown came downstairs for breakfast. 可能指 “边刷牙, 边下楼 。),分词的否定形式是在分词短语前面加上 not, never等否定词构成。,例如: Not fearing the fire, the child touched and got a finger burnt. 小孩儿不知道 怕火，用手去摸，把手指烫了。 Not knowing how to find the subway, I asked a policeman for help. 我不知怎样找到地铁，就去找警察帮忙。,I. 每空填一词，使该句与所给句子的意思相同。 1.
