区别in danger of 和 in the danger of

凡是带有the的都是特指，没有的就是泛指。
再比如：go to school 上学，是泛指，不强调上哪所学校
go to the school 上学校 ，意思是到某一所学校去，去的人也未必就是学生。

1.in danger of 处于…危险之中.比如：
The patient is in danger of death.
那个病人有死亡的危险.
The Jordan River is polluted and in danger of going dry.
约旦河已经被污染,且有趋于干枯的危险.
We must wake up to the fact that this kind of animal is in danger of dying out.
我们必须意识到这一事实,那就是这种动物正面临灭绝的危险.
2.in the danger of 处于...危险中,是特指.比如:
The teacher has been trying to hammer in the danger of failing the examinations.
老师一直试图反复强调存在着考试不及格的危险.
It is a disappointed thing that,however,these conventional pro-environment customary traditions are in the danger of becoming extinct or maybe extinguished already.
然而,令人遗憾的是,这些传统的环保文化正在面临消失的风险或已经消失.
