过去分词作状语的用法 【学习目标】 1. 学会运用分词作状语，并能够与状语从句灵活转换。 2. 学会运用过去分词的独立主格结构作状语。 【重点、难点】 熟练运用过去分词作状语及其独立主格结构作状语。 一．温故知新： 1. 现在分词与过去分词的区别： 现在分词表________________________ 过去分词表________________________ 2.过去分词作定语表示(及物动词和不及物动词)：________________________________________________________________________ 二． 合作探究 1. 过去分词作状语： 过去分词作状语可以： 1) 表原因：. 1 Moved by his words, I accepted his present. 2 Caught in the rain on my way home, I had a bad cold. 2) 表 ___________ 3 Asked how he broke into the room, he made no answer. 4 Discussed many times, the problems were settled at last. 3) 表____________ 5 Given more time, we could do it better. 6 Looked at from a distance, the painting seems more beautiful. 4) 表____________ 7 Built 30 years ago, the house still looks very beautiful. 8 Exhausted, they continued to work. 5) 表____________ 9 He turned away, disappointed. 10 He sat by the window alone, lost in thought. 即学即用： 把下面的分词作状语改成状语从句。 1 Looked at from a distance, the painting seems more beautiful. __________________ from a distance, the painting seems more beautiful. 2 Built 30 years ago, the house still looks very beautiful. __________________ 30 years ago, the house still looks very beautiful. 3 Discussed many times, the problems were settled at last. ____________________many times, the problems were settled at last.  4 Inspired by his teacher, he studies much harder. ____________________ by his teacher, he studies much harder. 注意：连词+过去分词作状语： 分词作状语时有时可以在前面加上一个连词，这时就相当于状语从句的省略。用连词+分词结构简化以下句子： 1 Water can be changed into vapor when it is heated. 2 Although he is encouraged by his parents, he still lacks confidence. 2.独立主格结构： With homework finished, he then watched a football game. With the toy broken, the boy was crying. 翻译：刷成了白色，我们更喜欢这个房子了。 ______________________________________________________ 分词作 ，其逻辑 须与主句主语保持一致。若不一致，分词形式须另带主语，从而构成复合结构的形式（名词+分词）作状语。这种结构称为“独立主格结构”。其中，主动用 ，被动用 。 3.独立分词短语： Judging from what you say in your letter, you are
