分词做状语时 逻辑主语必须和主句的主语一致，如果不一致，就用独立主格结构。即在分词前加上它的逻辑主语。
（1） Not receiving any letter from him,I gave him a call.
As I didn't receive any letter from him,I gave him a call
(2) Given more attention, the trees have grown better.
If more attention was given,the trees have grown better.
我没看出上面的句子需要变独立主格结构啊。（1）的逻辑主语好像和后面一样啊。（2）中的第二个句子它加逻辑主语了吗？ 望好心人士解释详细些。谢谢！

Answer 1

这两句的确逻辑主语都一致，所以都没有用到独立主格。

独立主格句子是这种：

The test finished, we began our holiday.
= When the test was finished, we began our holiday.
考试结束了，我们开始放假。

The president assassinated, the whole country was in deep sorrow.
= After the president was assassinated, the whole country was in deep sorrow.
总统被谋杀了，举国上下沉浸在悲哀之中。

Weather permitting, we are going to visit you tomorrow.
如果天气允许，我们明天去看你。
This done, we went home.
工作完成后，我们才回家。

The meeting gone over, everyone tired to go home earlier.
会议结束后，每个人都想早点回家。

He came into the room, his ears red with cold.
他回到了房子里，耳朵冻坏了。

He came out of the library, a large book under his arm.
他夹着本厚书，走出了图书馆
