There are several reasons why school uniforms are 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 {#blank#}1{#/blank#} (have) to worry about fashion(时尚). Everybody wears{#blank#}2{#/blank#} 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 {#blank#}3{#/blank#}gives off light in the dark. When the children are walking or {#blank#}4{#/blank#} (cycle) to school on dark mornings, car drivers can {#blank#}5{#/blank#} (easy) see them.

    But can uniforms help improve school standards? The answer {#blank#}6{#/blank#} this question is not clear. One study in America found that students' grades {#blank#}7{#/blank#} (improve) a little after the school introduced uniforms. But some students didn't want {#blank#}8{#/blank#} (wear) the uniform. Other American studies showed no {#blank#}9{#/blank#}(connect) between uniforms and school performance.

    School uniforms are {#blank#}10{#/blank#} (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.

    One day, Nick invited his friends to supper. He was cooking some delicious food in the kitchen. Suddenly, he {#blank#}1{#/blank#} (find) that he had run out of salt. So Nick called to his son, "Go to the village and buy some salt, but pay a fair price for it: neither too much {#blank#}2{#/blank#}too little.

    His son looked surprised. "I can understand why I shouldn't pay too much, Father, but if I can pay less, {#blank#}3{#/blank#}not save a bit of money?

    "That would be a very {#blank#}4{#/blank#} (reason) thing to do in a big city, but it could destroy a small village like {#blank#}5{#/blank#} (us), Nick said.

    Nick's guests, {#blank#}6{#/blank#}had heard their conversation, asked why they should not buy salt more cheaply if they could. Nick replied, "The only reason a man would sell salt {#blank#}7{#/blank#}a lower price would be because he was desperate for money. And anyone who took advantage of that situation would be showing a lack of respect for the sweat and struggle of the man who worked very hard to produce it."

    "But such a small thing couldn't {#blank#}8{#/blank#} (possible) destroy a village."

    "In the beginning, there was only {#blank#}9{#/blank#}very small amount of unfairness in the world, but everyone added a little, always {#blank#}10{#/blank#} (think) that it was only small and not very important, and look where we have ended up today."

    Many Americans put away their white clothes on Labor Day {#blank#}1{#/blank#} do not wear them again until the following May.

    One reason for the clothing custom relates to the season. In the United States, the {#blank#}2{#/blank#} (month) between June and September are summer. The weather is usually hot in northeastern cities. Many people there historically wore light-colored clothing in the summertime {#blank#}3{#/blank#} (keep) cool.

    Judith Martin is an expert on manners, {#blank#}4{#/blank#} spoke to Time Magazine about the history of wearing white in summer. She said Americans in the 1800s and early 1900s wore formal clothes all year long. Wearing white clothes in the summertime may make people more {#blank#}5{#/blank#} (comfort). Then, in about the 1930s, wearing white clothes in the summertime became fashionable. That is because some wealthy Americans went on vacation {#blank#}6{#/blank#} weeks or months in the summer. The white clothes then became connected with ease, {#blank#}7{#/blank#} (beautiful) and money. But at the end of summer, they put those white clothes away and {#blank#}8{#/blank#} (return) to their lives in the city, {#blank#}9{#/blank#} (wear) darker and heavier clothes. {#blank#}10{#/blank#} (eventual), not wearing white clothes after Labor Day became a bit of a fashion rule.
