Do you have to wear uniforms to school every day? Do you like them or you just want to wear your own clothes? Many students just wonder why they can't wear whatever they like, for teenagers want to be different from others.
In fact, there are several reasons why school uniforms are a good idea. First of all, uniforms help the school look smart. The students feel that they belong to a particular (特别的)group. When every student in the school wears the uniform, nobody has to worry about fashion. Everybody wears the same style of clothes. Uniforms can be useful in unexpected ways. A school in Ireland has introduced an interesting new uniform. On the edge (边缘)of the jacket, there is a piece of cloth which gives off light in the dark. When the children are walking or cycling to school on dark mornings, car drivers can easily see them.
But can uniforms
help improve school standards? The answer to this question is not clear 
One study in America found that students5 grades improved a little after the school introduced uniforms. But some students didn't want to wear the uniform. Other American studies showed that uniforms have nothing to do with the school performance.
School uniforms are traditional in Britain, but some schools are starting to get rid of them. Students of some very good schools do not have to wear uniforms now. However, uniforms are still popular. Pupils at about 90 percent of British secondary schools wear uniforms.
