生死的边缘英语怎么说

"On the brink of life and death" is a phrase that refers to a situation where someone or something is in grave danger or at a critical juncture, as if they are standing on the edge of a cliff, with life on one side and death on the other.
This phrase likely comes from the idea of a physical cliff or precipice, where if someone were to fall off, they could potentially be killed. However, the phrase can also be used metaphorically to describe any situation where the outcome is uncertain or there is a high risk of danger or harm.
Here are a few examples of how this phrase can be used in English, along with their translations in Chinese:
"The patient was on the brink of life and death when they arrived at the hospital." (病人到达医院时处于生死边缘。)
"The company was on the brink of bankruptcy, but a successful investment helped them turn things around." (公司濒临破产，但成功的投资帮助他们扭转局面。)
"The two countries were on the brink of war, but diplomatic efforts helped prevent a conflict from breaking out." (两国处于战争边缘，但外交努力帮助防止冲突爆发。)
