Question

有一个例句我不知道怎么回事
I found the door unlocked.
I went into the kitchen.
改成复合句就是
When I found the door unlocked,I went into the kitchen.
到目前为止我还明白,但是还可以改成是
Finding the door unlocked, I went into the kitchen.
这是为什么?什么情况下可以这样改?状语从句转换为现在分词结构又是怎么回事?
请帮我解答一下,谢谢!

将When I found the door unlocked,I went into the kitchen.改为Finding the door unlocked,I went into the kitchen.
是一种常见的从句简化现象.该句为条件状语从句,在满足when等副词引导的从句,与主句的主语的主语一致的前提时,可将when等连接词省去,将从句里的谓语动词变为V+ing的形式.这样这个从句就转变为一个修饰主句的修饰成分了.一定要满足那个前提才能这样变.
