当分词充当状语时，分词的逻辑主语和主句的主语是一致的（也就是说，分词必须依赖句子的主语。），即为“分词作状语”；若不一致，即为“独立主格”；而独立主格一般需自带主语，若省略其主语，则为独立主格的特殊情况，即为“悬垂分词”（初学者慎用）。如：

1.分词作状语，分词的逻辑主语是句子的主语。

Seeing those pictures, she remembered her childhood. 看到那些画，她想起了她的童年。

Accepted by the Party, he decided to devote his life to the cause of the Party. 入党以后，他决定献身于党的事业。

2.独立主格结构做状语，分词自带逻辑主语，并不依赖句子的主语。

Weather permitting, we'll go outing tomorrow. 如果天气允许，我们明天去郊游。

She being absent, the meeting had to be put off. 因为她缺席，所以会议不得不推迟。

3.悬垂分词作状语，分词无逻辑主语。

Judging from his accent, he must be from the South. 从他的口音判断，他一定是南方人。

Taken as a whole, there is nothing wrong with the book. 总的来说，这本书没有问题。
