=Because he was poor, the little boy couldn't go to school.（分词做原因状语可以改成这种从句）
He stood there, looking a bird in the tree.

Answer 2

你说的是不是现在分词作原因、伴随、时间状语啊。
原因：Being poor, he couldn't afford a TV set.
伴随："Can't you read?" the man said, angrily pointing to the notice on the wall.
时间：Hearing the news, he got excited.
