时光匆匆as time goes byTime flies (in haste)The rush of timeto rush the passage of timeThe hours trip rapidly awayThe time fleets awaytime is swiftThe time in a hurry flows throughSpeeding through life 岁月蹉跎 The years roll by -- spend one's life in fruitless effortsidle away one's timelet time slip by without accomplishing anythingThe years drift by 一起学习，呵呵。
