时间一去不复返

一寸光阴一寸金，寸金难买寸光阴。时间如流水一去不复返。

An inch of time is an inch of gold, which is hard to buy. Time is like running water.

叶子黄了，还有再绿的时候；天黑了还有再亮的时候；花谢了还有再开的时候；燕子飞了还有再来的时候。聪明的你，告诉我，为什么时间一去不复返呢？

When the leaves are yellow and green again, when it's dark and bright again, when the flowers are withered and open again, when the swallows fly and come again. Smart you, tell me, why is time gone forever?

暑假里，我平常很久才能完成的作业，我几天就做完了。放学回家时，我见太阳还没有下山，于是我飞奔回家，回到家后，看见太阳还没有下山，我高兴极了。我时时刻刻都在跟时间赛跑，因为时间就是生命，你要去珍惜它。

In summer vacation, I usually finish my homework in a few days. When I came home from school, I saw that the sun had not set, so I ran home. When I got home, I was very happy to see that the sun had not set. I am always racing with time, because time is life, you have to cherish it.

时间就像海绵里的水，只要愿挤，总还是有的。

Time is like water in a sponge. As long as you are willing to squeeze, there will always be.
