人教版高中语文《短新闻两篇》教案
罗森塔尔突破了“客观报道”“零度写作”的框框，把自己和其他参观者在奥斯维辛访问时的感受当做文章的主要内容来写，传达出每一个良知者的共同心声。教师总结：细节描写是耐人寻味的。文章没有阴森恐怖的镜头，没有血腥的画面，只是重现了新闻的事实真相，但透过细节却能引发人们对生命，对人性的思考。在作者看似平静的叙述中抒发了对德国纳粹残酷暴行的沉重控诉，更表达了作者对自由、和平与祥和的向往四、拓展延伸：《奥斯维辛没有什么新闻》这一作品本身的价值在哪？社会价值又在哪，能不能从这两个角度思考，几人合作试写一段颁奖词？范例：《奥斯维辛没有什么新闻》突破新闻“零度写作”原则，着眼细节，以冷峻的视角，深沉地描述了今天的奥斯维辛集中营纪念馆。在恐怖与快乐、战争与和平、历史与现实的反差中，它召唤起人们关于灾难的记忆、关于生命的思考、关于人性的自省。它的发表充分地表现了一个新闻记者的使命感，更以迫人的力量震撼生者的心，成为新闻史不朽的名篇。
