There are three paces of time: the future is like an arrow flies be long in coming, now, the past is always at a standstill. - Schiller.

时间的步伐有三种：未来姗姗来迟，现在像箭一样飞逝，过去永远静立不动。--席勒。

How time flies! Three years passed in a blink. Lots of memories left in my head. Teachers, classmates, hard work and above all friendship stay in mind.

时光飞逝，一眨眼三年就过去了，许许多多的往事还历历在目。所有的老师和同学、辛勤的汗水以及珍贵的友谊，始终在我脑海挥之不去。

How time flies! It's three months since I saw you last.

光阴似箭，我们已经三个月没见面了。
