Some fish are forced to leave polluted water and are flying in the sky. But unfortunately, air is also so polluted that they have to wear masks. Each of them is crying, “Where is my home?” What a terrible sight!
Mankind has brought so much pollution. Waste is being poured into rivers and seas. Poisons to kill pests in farming and chemicals go into rivers and seas, too. Poisonous gasses from factories also make the air so dirty. The whole balance of nature is being destroyed as a result of our ignorance of the environmental protection.
Personally, man can not live alone on the earth. Should fish die from serious pollution, so would man! It is high time we did something to prevent such a scene from happening.
分层教学是依据孔子的“因材施教理论”。宋代学者朱熹也说过:“圣贤施教,各因其才,小以成小,大以成大,无弃人也。”也就是强调了“注重学生个体差异”,“坚持平等教育,不追求平均发展”这是在承认学生存在差异的基础上,对其进行有差异、有层次的教学,把某些水平相当的学生划为同一层次,既可照顾学生个体间存在的差异性又可把因材施教提高到可操作的水平。
本文格式正确,意思表述完整,行文流畅自然。作者在写作过程中注意长短句并用,还使用了以‘which,’引导的非限定性定语从句,从而使文章层次分明,富于变化,不愧为考场佳作。
