hang by a thread 千钧一发【11.02】
hang by a thread 千钧一发
If something hangs by a thread, it is in danger, and likely to fail in the near future。hang by a thread的表达和中文中形容危在旦夕，十万火急的“千钧一发”十分相似。
Examples,
Peace and democracy hang by a thread in this troubled country. 在这个动乱的国家，和平和民主都摇摇欲坠，没有保障。
Roberta was told that her job hung by a thread, and she needed to be more serious about it. For several days after the accident, his life hung by a thread. Roberta得知她的工作正处于危机之中，她需要对此更认真一些。在事故后的几天，他命悬一线。
