44 Time is life and when the idle man kills time, he kills himself.

时间就是生命，浪费时间就等于浪费生命。

45 Time is a file that wears and makes no noise.

时间如锉，细磨无声。

46 Ordinary people merely think how they shall spend their time; /a man of talent tries to use it.

普通人只是想到如何度过时间，有才能的人设法利用时间。

47 Time and tide wait for no man.

时间不等人。

48 To choose time is to save time.

合理安排时间就是节约时间。

49 Time lost cannot be recalled.

时光一去不复返。

50 Never put off till tomorrow what you can do today.

今日事，今日毕。

51 Tomorrow never comes.

我生待明日，万事成蹉跎。
