From my point of view, graffiti is so ugly to look at. It’s a kind of pollution as well as an ill behavior. Moreover, public buildings are symbols of civilization, not the places to express our thinkings and ideas.

Consequently, I think graffiti should be prohibited by our school regulations. Those who don’t want to get rid of this bad habit must be punished strictly. In conclusion, we must clear out this bad manner, in order to create a good atmosphere for us to study.

最近，在许多大学校园里随处可以看到涂鸦，这些带给我们不愉快的视感。更糟糕的是许多学生却将涂鸦当作一种艺术，我对这种现象感到很烦恼。

在我看来，这些涂鸦看上去很丑。这是一种污染，也是种病态的行为。此外，公共建筑是文明的象征标志，而不是用于表达我们思想和主意的地方。

因此，我认为校规应禁止涂鸦行为。那些不想放弃涂鸦的人应该受到严厉的处罚。总之，我们应改掉这种陋习，这样才能创建一个良好的学习环境。
