Post-writing
Why can’t we find blue whales in Arctic Ocean Read and find the answers.
The blue whale is the largest animal on Earth, but you won't find them in the Arctic Ocean. Why
The main reason is food. Blue whales love to eat Antarctic(南极洲) krill (磷虾). These tiny shrimp(虾) are super abundant(丰富的) in the Antarctic But the Arctic doesn’t have too much krill, so there isn’t enough food to live blue whales..
Also, the Arctic Ocean is often covered with thick sea ice. Blue whales need to come up to the surface to breathe, and the ice can block their way.
Finally, blue whales have always lived in warmer waters and around Antarctica. They are just not used to living in the Arctic.
Reason 1: No enough food
Reason 2:
Thick sea ice
Reason 3:
Warm waters
Post-writing
Read paragraph 2, and think about what is “Whale Fall”
Blue whales can live up to 90 years. When a blue whale dies at sea, it becomes food for many kinds of animals living in and around the sea. This food lasts for over a year and it helps to create a lively and healthy ecosystem. Blue whales play an important role in our world, so we must protect them.
Blue Whales are important in our world, we can not live without them. So we should protect them!

板书设计
教学反思 【亮点】 本课围绕蓝鲸主题展开教学,亮点在于通过分层任务设计较好地落实了语言目标,学生能够运用目标句型完成信息提取和角色扮演,课堂参与度较高。不足在于拓展环节部分学生在语法综合运用上仍显吃力,个别学生未能准确把握比较级与最高级的区别。 【不足与改进】 下节课需增加语法对比练习环节,提供更多可视化例句和句型支架。同时可安排小组互评活动,让学生在实践中巩固语言知识。后续还应设计更贴近生活实际的主题任务,促进学生语言能力的迁移运用。
