Recently I was walking in town when I saw a group of school
students in uniform.I was shocked to see that the girls's skirts were very
short and they were wearing a lot of make-up.The boys looked very untidy.Their
shirts were dirty and some of them even had their shirtfronts open.I noticed
too that some of the students had pierced ears and noses,which I don't think
should be allowed at school.
　　And the other day,I was riding on the subway when I saw
some boys from a local school.I know they were from this school because they
were wearing the same uniform as my children.Instead of sitting quietly,these
boys were making a lot of noise,chewing gum in an ugly manner,and using bad
language.All the other passengers were looking at them and wondering how it was
possible for these boys not to have any self-respect(自尊).They were also giving
their school a very bad image(形象),which is shameful(羞耻的).
　　I am a mother of two teenagers at this school and I am
worried that my children also behave like this and I do not know about it.Do
school students know what is allowed and what is not allowed when they are
wearing their school uniform?I think the school should be stricter with the students.(1) And I think all students should be taught how to be polite.
