Step 1 Greeting (1 min) This step is to warm the students up before the class, and lead in the topic. Step 2 Environmental Problems (3 min) Show students the pictures of some environmental problems and use 5 sentences of the present perfect passive voice to describe them. The step is to expose the students to the structure and lead in the topic “environment”

After students learn these 5 sentences, teacher will ask them to summarize the basic structure of the present perfect passive voice.

And after they discover the structure, teacher will ask the students to reread the passage they learned before and find out the sentence with this structure. This task is to make sure that the students know the structure and understand the structure in some complex sentences. Step 4. Apply the structure (27min)

These two discussions are designed to raise students’ awareness of environmental protection and let them know the importance of cooperation.
