It is too I ate for a galloping horse to stop at a clip; it is use I ess for a sinking boat to be mended in the middle of a river,

马到悬崖收缓晚，船至江心补漏迟。(gallop:飞跑，奔跑)。

It is too I ate to cast anchor when the ship is on the rock.

错过时机再补救，为时已晚。

It is too I ate to grieve when the chance is past.

错失良机，后悔已迟。

It is too I ate to lock the stable door when the steed is stolen.

贼走关门，为时已晚。

It is too I ate to shut the stable door after the horse has bo I ted.

马匹脱跑 才关门，为时已晚。(bolt:拴住)。

It，s the early bird that gets the worm.

早起的鸟儿有虫吃。

Life is but a span.

人生苦短。

Life is half spent before we know what it i s.

人过半百，方知天命。

Lose not time; be a I ways employed in something useful; cut off all unnecessary actions,

不要浪费时间，做有益的事情，停止一切不必要的活动。
