分词短语做状语 1.分词作状语实际把状语从句简化。简化的条件：其逻辑主语一定要与主句的主语保持一致。While he was reading the book，he nodded from time to time.Reading the book，he nodded from time to time.Because he was shy，he didn’t come to the party.Being shy，he didn’t come to the party.As the book is written in simple the book is easy to read.Written in simple the book is easy to read.2.分词作状语时可分为以下几种形式：doing：用来表示主动，且前后动作同时进行。Returning home later，my friend learned that the police had been to the flat.having done：用来表示主动，且动作发生在主句之前。Having seen the film before，I decided not to see it again.being done：用来表示被动，且前后动作同时进行。Being questioned by the police，he felt frightened.done：用来表示被动且完成Destroyed in the storm，the house will be rebuilt.having been done：用来表示被动，而且强调动作持续 一段时间或次数。Having been defeated three times，he had to give up.否定形式：not/never+分词结构Not studying hard，he 。
分词短语作状语句型 一。现在分词短语作时间状语有以下三种情况：1．分词动作一发生，谓语动636f707962616964757a686964616f31333361323530作紧跟着发生，这时用现在分词的一般式作时间状语，其逻辑主语为句中的主语。常用的动词，如：hear，see，arrive，return，get to，look，open，close，leave，turn around，walk等，表示一个极短暂动作。此种情况可以换作on+动名词，表示相同的意思。译作\"一（刚）…就…。此种情况也可以换作是when引导的时间状语从句，该从句的动词多用一般过去时表示。如：Hearing their teacher's voice，the pupils stopped talking at once.（=On hearing their teacher's voice…=When they heard their teacher's voice，the pupils…）一听到教师的声音，学生们立即停止讲话。2．谓语动作发生在分词所表示的动作过程之中，则用when/while+现在分词的一般式，分词的逻辑主语为句中的主语。此种情况可以用in+动名词的一般式代替。也可以换作when、while引导的时间状语从句，该从句的谓语动词用进行时态。如：Don't be careless when/while having an exam.=Don't be careless in having an exam.=Don't be careless when/while you are having an exam.考试时不要。
过去分词短语做状语如何理解及还原？ 请问各位大神！Developed most probably as a defence against forest fires，the bark of the cork oak…
