时光匆匆
as time goes by
Time flies (in haste)
The rush of time
to rush the passage of time
The hours trip rapidly away
The time fleets away
time is swift
The time in a hurry flows through
Speeding through life
岁月蹉跎
The years roll by -- spend one's life in fruitless efforts
idle away one's time
let time slip by without accomplishing anything
The years drift by
一起学习，呵呵。
