being+adj现在分词做状语是常见情况，这里的being careful做的伴随状语。这里的being可以省略，直接用形容词做状语。

1. 形容词做原因状语，being可以省略。

Being late, she was scolded by the teacher.

Being ill, I stayed at home.

2. 形容词做伴随状语，一般不加being.

He got home late that night, tired and exhausted.

另外being done状语和后置定语表示正在进行的动作。

That is the teaching building being built.

being built做后置定语，“正在修建的”

Being interviewed by the reporters, the manager has no time to see you.

being interviewed做时间状语，表示被动进行。
