The kids at Shute Country Primary School in Devon are surprisingly quiet when it’s time to go home in the afternoon, instead of the usual shouting and running you can hear them asking each other, “ Are the lights all off?”, “Shall we check the taps in case they are dripping （滴水）?”, “How many paper towels did we use today?” But it’s not unusual here．The kids have declared a war on waste． “We’ve never made the children do anything,” explains Liz Templar, the school’s head teacher, “they came up with all ideas themselves．They’re doing this because they want to．” If you take a look around the school you won’t see anything thrown away unnecessarily．Everything is collected and reused, or sent to be recycled． Shute School started its green_revolution_two years ago．They looked carefully at every party of school life－from the teaching to the cleaning．They looked at the way stationery（文具） was used－especially photocopying, the way cleaning was carried out, and how food was used and wasted! Even parents were looked at: how many children came in each car? Did they use unleaded petrol? Could they bring more children in fewer cars? High on the list was the waste of paper．Next came unfriendly cleaning products．Paper towels were replaced with recycled paper．But the hardest thing for the kids was when they found out how much rubbish was created by the chocolate, crisps and other snacks（小吃） eaten at lunch time．Of their own accord（自愿地）, the children gave them up．Now they bring apples and home-made snacks． The school has its own garden where they grow vegetables and flowers so that they can learn about the environment．They also use this area for their recycling store-large containers to collect aluminum, bottles, plate and fabric（织物）． Even the school’s play area is made from recycled things． Since the children started, the school’s heating and lighting bills have fallen obviously and the number of rubbish bags has gone down from seven a week to two or three． Everywhere in Shute School there are bright posters asking everyone to take their rubbish home, to save energy and paper and to keep the green flag flying． 1．Which of the following best describes the writer’s idea?
