分层作业设计 基础巩固: Listen to 3a. Then recite it. 设计意图:熟记本课重点单词和短语。 能力提升: 1. Write an article about a kind of endangered animals to call on people to save them. 2. Review the grammar that we have learned today and do exercises in your exercise book. 设计意图:巩固所学的用法。
教学反思与改进 本节课通过图片导入,学生兴趣很高,参与度广。阅读任务有梯度,为学生完成阅读任务降低了难度。在拯救濒危动物的讨论中,学生思维活跃,视野开阔。他们能选择自己喜欢的动物,说明濒危的愿意及拯救措施,语法项目也能达成学习目标,但因该部分较为枯燥,学生兴趣略有降低,下一步考虑在有趣的语境中学习语法。

Para2.
1. Why is it harmful to the environment (4.5)
Sharks are at the top of the food chain in the ocean’s ecosystem. If their numbers drop too low, it will bring
danger to all ocean life.
2.Sharks can never be endangered because
they are the strongest at the food chain.(6.7.8)
)
True or False:
at the top of the food chain
in the ocean’s ecosystem
浮游生物
sharks
at the top of the food chain
in the ocean’s ecosystem
因为我们生存所需的氧气的70%是海洋中的浮游生物提供的,鲨鱼一旦灭绝,没有了天敌控制的其它海洋生物就会大量吞噬海洋浮游生物,造成地球的缺氧。海洋是地球上最重要的生态系统,起到调节气候和为其它生物提供食物的作用,因此拯救鲨鱼其实就是在拯救人类自己。
