独立主格结构就是 “逻辑主语 +分词、形容词或介词短语”，只要把前面的句中的谓语动词改为分词或留下形容词/介词短语就可以。
1. Our homework , we went to play football. 〔时间状语〕2. The meeting , he went back home. 〔时间状语〕3. Time , we shall visit the zoo.〔条件状语〕4. She stood there, tears down her cheeks. 〔伴随状语〕5.

状语从句改写为分词短语算伴随状态吗
如果主句和状语从句的主语一致，状语从句可以略去主语改
本句的 be careful 是祈使句，主语是省略的 you，从句 when you cross the street 中的主语也是 you，所以可以改写如下：Be careful when crossing the street.另如：He is very strict with them, whilehe loves his students. 虽然他爱他的学生， 可是他对他们很严格。
-- 可改写为 He is very strict with them, while loving hisstudents.I'll do it if I die in the attempt.即使会丧命我也要试一下。
-- 可改写为 I'll do it if I dying in the attempt.
用非限定分句改写句子
第一句中的while因为要表达在read这个动作发生的时候，waiting这个动作是延续的，用while来表达两个动作的时间关系。
如果去掉则会表达不准确。
第二句实际是过去分词引导状语从句的典型案例，直接用过去分词来表被动，表完成，两句逻辑主语虽没有出现，但是一致的必然是WE，所以可以直接构成句子。
