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 shirt fronts open. I noticed that some of the students had their ears and noses pierced, which should not be allowed at school.And the other day, I was on the subway when I saw some boys wearing uniforms of the same local school. Instead of sitting quietly, these boys kept making noises and saying dirty words. All the other passengers were looking at them and wondering how it was possible for students like these boys. They were really showing a bad image （形象）of their school, which was shameful.I am a mother of two teenagers of the same school. After seeing those boys and girls, I am worried if my children also behave like this. I don’t know about it. Do students in this school know what is allowed when they are wearing the school uniforms ? I think the school should be stricter with the students. And I think all the students should be taught how to be polite.1.Why was the writer shocked at about the girls’ skirts?__________________________________________________________________________________2.Where did the writer see the badly-behaved boys?__________________________________________________________________________________3.What bad image did these badly-behaved boys showed?_____________________________________________________________________________4.How many children did the writer have?______________________________________________________________________________5.What does the writer think all the students should be taught?_____________________________________________________________________________
