At the moment, high school students in the state of Philadelphia, USA, can wear their own clothes. However, next year the high schools must do one of the following:
●Either make students buy school uniforms (in other words, all students must wear the same uniforms)
●Or say which colors must be worn, but let students buy their own clothes in these colors
A survey made at Central High School, Philadelphia, showed that most of the students didn't think that wearing school uniforms was a good idea.
Rachel didn't like the idea of a uniform in the slightest. “It makes us look like prisoners (囚犯). Everyone's different, so why is the school trying to make us all the same?”
Sandra was wearing a brightly-colored shirt with her jeans. “No one else wears a shirt like mine, ” she said. “I'm the only one, and I like that. I can understand that the school needs a dress code (准则). It's a problem if students come to school with their shirts open. We all understand that, but no one wants a uniform. Even my mum thinks it's silly.”
Only one student, Ben, said he didn't mind wearing a school uniform. He said, “I used to wear a school uniform when I lived in Australia for a year. It wasn't so bad. You can wear a uniform and still be tidy. We used to wear grey trousers, a round-necked shirt and a jacket in blue or green. It wasn't a problem.”
