    With air pollution making much difference to many of Chinese cities, parents are calling for the installation(安装) of air cleaners in classrooms. There has been much debate over whether air cleaners should be used in China's schools. Some parents have donated cleaners to their children's classrooms, while others raise money together to make the purchase(购买). “Our school bought air cleaners last year. We did a little fund raising, with each parent throwing in several hundred for that,” said one parent.

    However, the idea of installing air cleaners for all the classes has been refused by some schools. Liu Liangcheng, vice-principal of Beijing's Taipinglu Primary School, says installing air cleaners bought by parents may lead to problems. “We have refused air cleaners bought by parents before, as there are clear and strict rules against educational fees. We can't just break the rules here. And without standard guidance (指示) from local authorities(权威部门), it is hard to decide on the brand of the cleaner, installation and even safety of the device(设备).”

    Moreover, experts say air cleaners can cause other health problems. Deng Gaofeng who works for the China Academy of Building Research says. “ In the classroom, if we keep windows and doors closed, the concentrations (浓度) of CO₂ will double from 1,000 PPM to some 2,000 PPM. According to national safety standards, the highest level should not be more than 1,500.” In addition, experts say air cleaners on the market are mostly designed for homes or offices. Evaluation(评估) is needed to know whether they are suitable in classrooms.

    It seems whether air cleaners should enter China's schools is an ongoing question. It still requires a more detailed plan.

Topic : Should air cleaners be installed for students in school?

    Many young people would like to go to west China to help children to study. One of them, Lu Yi, was a university student. One day, when she went to a small village in Guizhou, she saw the poor children herself. She felt sad. She thought she should do something for them. So she decided to stay there and to be their teacher. Money is the biggest problem for her. But she didn't give up. She worked hard and her students like her very much. After graduation(毕业), she went back to that village at once and she worked as a volunteer teacher for five years. She worked hard and her students liked her very much. When the journalist at the CCTV Station interviewed her, she said she liked being a good influence(影响). She said she hoped to change the poor children's lives. She enjoyed the time as a volunteer very much. She would try her best to help the poor children.

Information Card

    School is not the safe place as it used to be. How to help students stay away from danger? There are many activities that teachers can do to teach safety in an easy way. Here are some stories from the students who have had the safety class in NO.1 Middle School.

    Milk Smith: About Sports Safety

    Once, our head teacher made up a story about sports safety. All we needed to do was to point out safe and unsafe sports behaviour in the story. From this lesson, we knew we should always do warm-up exercises before playing sports and drink some water after that.

    Amy Young: About Classroom Safety

    Yes, making up stories is a good way to learn and enjoy ourselves. We were once asked to make up a story about a boy called Naughty. He always did something naughty in the classroom and got himself into trouble. In this way, we learned to behave well and get on well with each other.

    Frank Green: About Fire Safety

    In our school, we have a fire emergency response practice(火灾应急演习) in September every year. So we know where to go if there is a fire in school. We learn to use the fire extinguisher(灭火器), too. But I don't think we should be allowed to put out the fire alone. It's too dangerous for young students like us.
