Unit 1 Knowing me, knowing you Section Ⅱ Using language 【语法精讲】 过去分词（短语）作状语 教材链接 用所给动词的适当形式填空 1. （教材P2）Disappointed（disappoint） by his behaviour, I said all this to my best friend. 2. （教材P3）Treated（treat） this way, you’re sure to feel hurt... 3. （教材P4）Approached（approach） in this way, your friendship will soon be repaired. 上面三句中，三个动作（disappoint, treat, approach）分别与其逻辑主语I，you和your friendship是被动关系，因此用过去分词形式做状语。 要点精析 一、过去分词（短语）作状语 过去分词（短语）作状语,可以表示时间、条件、原因、让步、方式或伴随等,相当于一个状语从句。其逻辑主语一般与句子的主语一致,且与句子主语之间构成逻辑上的被动关系。 1.过去分词（短语）作时间状语,相当于由when或while等引导的时间状语从句。 Invited for a meal, you might ask, “Can I bring anything?” =When you are invited for a meal, you might ask, “Can I bring anything?” 受邀吃饭时，你或许问：“我可以带些什么吗？” 2.过去分词（短语）作条件状语,可转换为由once、if或unless等引导的条件状语从句。 Exposed to light, the film will be damaged and get useless. =Once it is exposed to light, the film will be damaged and get useless. 一旦曝光，胶卷就要被损坏而不能用了。 3.过去分词（短语）作原因状语,可转换为由because、as或since等引导的原因状语从句。 Greatly inspired by what he did, I joined him in helping others in need. =Because I was greatly inspired by what he did, I joined him in helping others in need. 由于受到他所做事情的极大鼓励,我和他一起来帮助需要帮助的人。 4.过去分词（短语）作让步状语,可转换为由though、although引导的让步状语从句。 Built before the war, the engine is still in perfect condition. =Although it was built before the war, the engine is still in perfect condition. 尽管是战前制造的，这台发动机仍然处于良好状态。 5.过去分词（短语）作方式或伴随状语,常可转换为并列分句,位于句首或句末。 Surrounded by his students, the teacher went into the lab. ＝The teacher was surrounded by his students and he went into the lab. 老师被学生们团团围着,走进了实验室。 [易错提醒] before、after一般不与过去分词连用,因为这两个词还可作介词,后接being done的形式。 The doctor reached the hospital in a hurry after being called in for an urgent surgery. 接到紧急手术通知后，医生急忙到达医院。 二、过去分词（短语）作状语时在句中的位置 过去分词（短语）在句中作状语,放在主句前时,后面用逗号与主句隔开；放在主句的后面时,前面用逗号与主句隔开。 Grown in rich soil, these seeds can grow fast. 如果种在肥沃的土壤里，这些种子能长得很快。 He stood there silently, moved to tears. 他默默地站在那里,被感动得热泪盈眶。 三、过去分词（短语）与现在分词（短语）作状语的区别 过去分词（短语）与句子主语之间存在逻辑上的被动关系；现在分词（短语）与句子主语之间存在逻辑上
