and this newspaper believes that,as an insurance policy against a catastrophe
that may never happen,the world needs to adjust its behaviour to try to avert
that threat.
as 是否引导非限定性定语从句?
不是.
楼主可以分析一下它的结构:an insurance policy against a catastrophe that may never happen
很明显,that may never happen是定语从句修饰前面的a catastrophe,而against a catastrophe是一个介词短语,前面又只是一个名词结构an insurance policy.
整个成分根本就不是一个句子,它只是一个由两个定语成分叠加修饰的名词短语而已.
所以,as引导的不可能是非限制性定语从句,只是一个名词短语.
