关于环境保护的调查报告
一进校门，我被眼前的一切惊呆了，新种的小草枯萎了，上面还有几张纸片，大树上的叶子也枯黄了，顶上还有许多垃圾袋，整个学校遍地垃圾，短短的几天时间怎会使学校这般模样呢？于是，我对学校的环境卫生进行了调查。
[调查]
我用目测法目测了学校受污染的面积有半个学校那么大，而且污染的地区上都有垃圾袋、饮料瓶、零食包装等垃圾。又用询问法询问了一些大哥哥、大姐姐，可他们却说：“这又不是我们的包干区，又不用我来扫。再说了，丢到他们的包干区里，扣他们的文明分，我们班就可以当选文明班了，干嘛不丢。”
[分析]
1、草地上的垃圾袋可能是在食堂里吃午点的同学把袋子扔在草地上的。
2、树上的垃圾袋可能是小同学把袋子扔着玩，不小心扔在了树上。 3、草地上的零食包装可能是一些大姐姐们为了自己班的利益才丢进了别班的包干区里的…… [结论] 学校卫生环境污染的原因：
1、有同学在食堂吃午点，吃完后把袋子随手乱丢，现在又是雨季，一下雨，袋子渗进土地里，袋子里的化学物质污染了土地，使小草也受到了污染致使小草死亡。
2、有同学把袋子扔在了树枝上罩住了树的叶子，使树叶因不能吸收新鲜空气而枯黄。
3、有些高年级的哥哥因为自己班的利益而把垃圾袋扔在了别班的包干区里致使草儿被压死……
大量的事实告诉我，我们美丽的校园之所以变成这样，是因为各种人为的因素造成的，因为死了的花草较多，学校又要花一大笔钱去美化，真是一笔巨大的浪费。

　　time on housework will be rewarding being gradually aware of the significance in children’s involving in housework, parents are changing from a role of overprotection to a more reasonable level of encouraging initiative participation in household chores. it’s inspiring and meaningful to see that children are no longer deprived of their rights to develop practical skills in housework, instead, they are given the chances to contribute their shares and are often rewarded with a spiritual fulfillment. fortunately, i’m one of the countless teenagers who have benefited a great deal from this kind of perceptual transition of our parents. i have frequently been encouraged to deal with cooking the meal, sweeping the floor as well as washing dishes since an early age of seven. and i am proud enough to take the responsibility of preparing a good meal when mom and dad are delayed by their work. thanks to their early realization and ever-lasting persistence in the cultivation of my independence, i have grown more skillful and willing to take my share of obligation either at home or at school. pushing the children on their way to housework is initial yet effective if parents tend to ensure a promising future
