试 OG12-118 中的 嵌入式关系分句

june30

a phenomenon that most scientists agree iscaused by human beings' burning of fossil fuels1） that iscaused by human beings' burning of fossil fuels 是 a phenomenon 的定语从句
2）a phenomenon is caused by human beings' burning of fossil fuels 是 most scientists agree 的宾语从句
所以 这句话 是 嵌入式关系分句？而


，a phenomenon that most scientists agree is caused by human beings' burning of fossil fuels， 作为整句话 The world wildlifefund has declared that global warming, a phenomenon most scientsts agree tobe caused by human begings in burning fossil fuels, will create havoc amongmigratory birds by altering the enviroment in ways harmful to their habitats. 插入语？

bitieming

most scientists agree是插入语
去掉后是a phenomenon that is caused by

a phenomenon that most scientists agree is caused by human beings' burning of fossil fuels作为整个句子的同位语？ok的
