every second counts
means: every second is important.
每一秒都很重要,争分多秒,一寸光阴一寸金啊。
关于这个count,记得电影《泰坦尼克号》的结尾处Jack和Rose在冰冷的海水中,身体僵硬的Jack对坚持不下去的Rose说:Make everyday count.(惜时如金。)
请看例句:
The time of life is short. So, now every second counts.
生命是短暂的,从现在开始我们必须争分多秒。
The examination is just round the corner. From now on, every second counts!
考试即将来临,从现在起惜时如金。
