批改：
1. boys and girla : 开头称呼单词拼写有错误。
2.it's an universal phenomenon that many students often waste food and let the water running after washing , 首先，冠词使用错误；其次，后边应该是动词原形。
3. we may develop the form of much bad habits in turn . 本句话说的啰嗦，直接就说 our bad habits will be developed.
评析：
本文是一篇发言稿，所以在格式上应该符合发言稿的格式，比如在最后落款没有发言人的姓名等；其次中间出现了几个语法错误，而且书写不是太规范。希望继续努力！！！
