(Ex 1, 2)教学反思：本单元主要介绍海底世界里的动植物，海底的世界奥妙无穷，有绚丽多姿、美轮美奂的植物，也有色彩斑斓、凶狠残暴的动物，鲨鱼就是学生最感兴趣的一种海底动物，特别是看过一些关于鲨鱼的电影录像等，学生总对其保持着一颗好奇心。如此凶残的动物却也能与人类合作。第一篇阅读就是介绍了“海上霸王”虎鲸如何帮助人类捕杀其他鲸鱼、以及保护人类的两个故事。在导入部分，先向学生展示一些海底动植物照片，让学生对海底世界有个基本了解。再联系课文，给学生播放关于虎鲸袭击大白鲨以及人类的视频，通过视频的观看，让学生对虎鲸有更直接的了解，因此也能激发学生对动物的爱护以及人类应该如何与动物相处的思考。课文讲解采用读前、快速阅读、仔细阅读、读后四步阅读技巧，让学生对课文内容把握到位。而在讨论部分，结合捕鲸话题，让学生自由探讨，深思人们对“鱼翅”消费的问题，激发学生保护鲨鱼这种濒临灭绝的动物。通过这单元的学习，既能让学生了解关于海洋世界的一些基本知识，特别是关于鲸鱼、鲨鱼这些海底动物，还能让学生对人类与动物的关系进行反思，学完本课，学生对动物的保护意识能得到加强。不足的一点是，对于文科班女生居多的情况，捕杀鲸鱼的画面太过血腥，让学生觉得有些捕鲸人太过残忍，不过却也觉得发人深省。
