请分析下面这个句子的语法结构,特别是后面being的用法,
Many scientsts like Dr.Janice Foster believe that people have caused the increase in the earth's temperature through the burning of fossil fuel like coal,natural gas and oil to produce energy whose byproducts are called "greenhouse" gases,the most important one being carbon dioxide.

Answer 1

the most important one being carbon dioxide 是整句话的“伴随状语”
在书面语中,有时作者会用一个长结构的句子形式来表达“严谨的”语义,于是就出现了这种把一个完整的句子中的谓语动词用非谓语动词的形式来表现,如这个句子里的 being.其实,这句话完全可以独立出来而不影响整句话的意思：The most important one is carbon dioxide.
