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。
