我猜是伴随状语，对不对？

用动词开头的句子，要ing

独立成分吧，起补充说明作用

把每件事情都考虑进来 take in

状语

可以理解成（现在分词）做状语。
类似的句子比如：
studing in that school, i met him twice.= when i studied in that school , i met him twice .
this is the total cost of the holiday，taking everything in= this is the total cost of the holiday，and this takes everything in.

具体你可以看看 语法书- 非谓语- 现在分词-现在分词做状语 这里面的相关知识和例句就知道了 。
