Task 2. Read Para. 1 and think:

Have you heard of shark fin soup?

Where is shark fin soup popular?

Task 3. Read Para. 2.

What do people do with sharks when they catch them? (and)

What do you think of finning ? (not only , but also)

How many sharks are caught and traded every year?

Why do people cut off their fins and throw the sharks into the ocean?

What happen to the sharks after their fins are cut off?

Why is it harmful to the environment?

4. Guide the students to understand how the writer analyzes the problem. Make a stage summary of Para. 2

（设计意图：学生通过教师设计的问题进行文本的推进阅读，了解鲨鱼种群面临的危险境况并找出原因，回答时注意连词的使用练习。教师在第一和第二个问题之后精心设计了连环问题，引导学生进行深入阅读和思考，即Read between the lines，更近一步挖掘文章的深意，同时帮助学生清晰了解作者第二自然段的文章结构。再此过程中，适时提供视频资料进行背景介绍，帮助学生透彻理解文本所要表达的信息。为下面的讨论环节做好铺垫。）

Task 4. Read Para. 3.

1. Read Para. 3 and answer the questions:

What do the environmental protection groups around the world do to fight against “ finning” ?
