Our school is a beautiful school. It has a good environment. Most of
the students have good manners. But I find that a few students have some
bad manners. For example,I often see a lot of rubbish thrown about on the
grass or around the trash can in our school. It must be thrown by those
students who have bad manners. Also,some students like to draw pictures
or write something on their desks; school walls or other public places.
Some students often destroy(损坏)  the lights, doors or windows in their
classroom. Some of them run  in  the  corridors (走廊). Besides these,
some boys are easy to get angry.When having arguments with others,
they are most likely to begin to fightf And the bad behavior has a bad
effect on the reputation(声誉) of our school.
      In my opinion, we must take some ways. On one hand , the school
should punish (惩罚 ) those who have bad manners. On the other hand,
the teachers should each the students what are good manners and what are
ad manners. I hope more and more students pay attention to their behaviors
 in our school and have good manners.
