Unit 16 Lesson 63

2. The whale feeds on small fish.（what）
3. The sperm whale feeds on squid.（difference）
Discussion:
1. The whales are in danger. What’s your opinion about it?
2. The sea is being polluted. What should we do?
In my opinion, the blackboard design can reflect the teacher’s ability of mastering the text and leading the students to master the text easily.
In this text, the design is not easy to write. I write the topic sentences on the blackboard in order to tell the students that this is of the importance in this class. The discussion is of the difficulty.
I want to make the design inductive, instructive and artistic.
