There are several reasons why school uniforms(校服)are a good idea.First of all,uniforms help the school look smart.The students feel that they belong to a particular group.When every pupil in the school wears the uniform, nobody     1     (have)to worry about fashion(时尚).Everybody wears     2     same style of clothes.Uniforms can be useful in unexpected ways.A school in Ireland has introduced an interesting new uniform.On the edge of the jacket,there is a piece of cloth     3     gives off light in the dark.When the children are walking or     4     (cycle)to school on dark mornings,car drivers can     5     (easy)see them.

But can uniforms help improve school standards?The answer     6     this question is not clear.One study in America found that students’ grades improved a little after the school     7     (introduce)uniforms.But some students didn’t want     8     (wear)the uniform.Other American studies showed no     9     (connect)between uniforms and school performances.School uniforms are     10     (tradition)in Britain,but some schools are starting to get rid of them.Some very good schools don’t have a uniform policy.However,uniforms are still popular.Pupils at about 90 percent of British secondary schools wear uniforms.
