阅读理解。 In most schools, all students must wear school uniforms when they are at school. But not every student likes the school uniform. Li Jia, a 13-year-old girl from No.9 Middle School, said, 'I don't like my school uniform at all. It is too ugly. I think young girls should wear some colorful clothes. But, I have to wear it every day.' However, Su Yang, also a middle school student, has different opinions. He said, 'I like my school uniform. It is very beautiful. It is a symbol (象征) of my school and I like my school very much.' Mr. Chen, a teacher, told the reporter, 'It's good for the students to wear uniforms. It saves a lot of time and money. In the past, my daughter spent much time on her clothes. But now, she seldom (很少) asks me to buy clothes for her because she has to wear the school uniform.' Do you like your school uniform?
