You can see the pen on the floor now. I’ve opened the door. Now the door is open, etc. Ask the other students to write some sentences on the board, using the Present Perfect Tense. Circle have done in the sentences. T: Well, do you know the differences between the Present Perfect Tense and the Past Tense? Show the following to students.
