very popular.(once publishedonce it is published)一旦出版，这本词典将大受欢迎。2作原因状语。相当于一个原因状语从句。lost in thought，i didnt notice what was happening outside.(lost in thoughtbecause i was lost in thought)由于陷入沉思，我没注意到外面发生了什么事情。3作条件状语。相当于一个条件状语从句。given another hour，i can also work out this problem.(given another hourif i am given another hour)如果再给我一个小时，我也能把这道题算出来。4作让步状语。相当于一个让步状语从句。beaten by the opposite team，we didnt lose heart and encouraged each other.(beaten by the opposite teamthough we were beaten by the opposite team)虽然被对方的队打败了，但我们并没有灰心而是相互鼓励。5作方式或伴随状语。可以转换成一个并列句。the old man got on the bus，supported by a girl.(supported by a girland was supported by a girl)(方式)在一位姑娘的搀扶下，老人上了公共汽车。【注意】(1)过去分词作状语时，其前面可以带有相应的连词，如when，though，although，as if，as though，if，unless，until，once等，表时间、让步、条件、方式等。if (i am)invited，i will attend the wedding of my friend.如果受到邀请，我会参加我朋友的婚礼。(2)过去分词与句子的主语之间存在逻辑上的动宾关系，即表被动；现在分词与句子的主语之间存在逻辑上的主谓关系，即表主动。asked why he was late，he cried.被问到他为什么迟到时，他哭了。looking out of the window，i saw some students playing there.我朝窗外望去，看见几个学生在那边玩耍。(3)过去分词(短语)作状语时，分词的逻辑主语与句子的主语要一致。if caught，the thief will be punished by the police.小偷如果被抓，会受到警方的处罚。(4)有些过去分词已形容词化，作状语时表示人的状态。常见的有：satisfied，surprised，interested，moved，worried，pleased，disappointed等。disappointed at the examination results，the girl stood there without saying a word.因为对考试结果很失望，小女孩站在那儿一句话也没说。二、过去分词作定语1一般来说，过去分词作定语时含有“完成” 和“被动” 的双重意义。但要注意不及物动词的过去分词常表示“完成” 的动作，而不表示“被动” 意义。如：boiled water(开水)；fallen leaves(落叶)；risen sun(升起的太阳)等。my parents are both retired teachers.我的父母都是退休教师。2单个的过去分词作定语时，一般放在被修饰词之前，也可后置。往往可用定语从句代替。spoken english英语口语iced beer冰镇啤酒fried chips炸土豆条hurry up，there is only a little time left.快点，时间不多了。things seen are mightier than things heard.眼见为实，耳听为虚。3过去分词表示的动作通常发生在谓语动词之前或表示与句中谓语动词相应的经常性动作。all the windows broken have been repaired.所有坏了的窗子都已经修理好了。he is a teacher loved and respected by his students.他是一个受学生喜爱和尊敬的老师。一、用所给单词的适当形式填空1well
