任务型阅读。 Recently I was walking in town when I saw a group of school students in uniform. I was shocked to see that the girls' 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 uniforms 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 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. And I think all students should be taught how to be polite. 请依据该家长观察到的一些学生的行为，完成下列表格中的句子。 Be supposed to Not be allowed to Dress up as a school student wear very short skirt 1．one's ears or nose________ Keep uniform clean and tidy 2．make uniform ________ Behave politely 3．________ when talking Obey the public rules 4．Make ________ in public
