I do not know the reason why some people want to get up late. They will never have the opportunity to enjoy (of　enjoying) the fresh air and calmness of the morning. This is indeed a quite regrettable thing.

　　To rise early is a good habit (which) we should cultivate. Why? Because the best time when we can pursue our studies　is in the morning. In addition, early rising is also good to our health. I hope that everybody our knows the reason why　we must rise early.

　　我不知道某些人要晚起的理由。他们永不会有机会来享受早晨的新鲜空气和宁静。这真是一件发令人遗憾的事情。

　　早起是我们应该养成的一种良好习惯。为什么?因为早晨是我们从事学业的大好时间。再者，早起对我们健康也有益处。我希望每个人应该知道我们必须早起的理由。
