鲨鱼

下周上堂关于鲨鱼的公开课。

上课导入部分，可以让学生讨论对鲨鱼的第一印象，用一些词来描述这个动物。What's your feeling about this animal? Can you think of some words to describe it? It's terrifying. It's very huge and powerful. It can even eat man so it's dangerous. Or it's endangered. If one animal is endangered, the animal may soon not exist because there are very few now alive.

导入部分，让学生想出尽可能多的词来描述鲨鱼，让学生动起来。然后就导入文章：

Today, we are going to talk about sharks. And the title is sharks: dangerous or endangered? Here our author uses a question mark. From the title, we don't know what the author mainly wants to talk about. You can make a guess.

学生猜测之后，就进入快速阅读。

Please skim the passage and find out what the author focuses on. You can just read the first and last sentence of each paragraph.

From the basic information, we can conclude that the author focuses on endangered.

快速阅读之后，来到仔细阅读。

1. Show the poster of film Jaws

4. Next, I want to read paragraph three carefully and find out another reason why sharks are endangered.
