Recently we have held a class meeting to discuss what is considered to be honorable behavior and what is shameful. （最近我们班开了个班会讨论什么是光荣和耻辱。）It is really a pity to see all this in our school.（很遗憾在学校看到这些现象）Some students don’t respect their teachers or parents. （不尊敬老是和父母）Some don’t take their studies seriously and cheat in exams. （作业不认真，考试作弊）Some throw wastes everywhere and pollute the environment . （到处乱扔垃圾污染环境。）It is honorable to obey the law and rules , care much about our class and study hard.（关心班级、努力学习、遵纪守法是光荣）It is shameful to break school rules, to be selfish or to make little effort to achieve success.（违反学校纪律、自私 骄傲是可耻的）We should respect others and think more of them than of ourselves.（我们应该尊敬别人经常关心别人）We should work hard and make much more progress to repay the society.（我们应该努力学习取得更大进步从而回报社会。）We should try our best to keep the environment clean。（我们应该想方设法保持干净的环境。）
人与环境是和谐相处的，我们生存在地球上，人是自然之子，而不能仅把人看作自然的征服者，大家都知道，人类只有一个地球，地球上的山山水水、动物。植物是人类的细胞，如果我们把它损坏了，破坏了大自然的组织，等 于消灭人类。因此，环境要与社会公德联系起来，与实践行为作为人格教育的一项重要内容来抓。每个人都要履行保护环境的责任和义务。
