There is too much repetition. It helps the learners master the lines in the cl but they cannot make their own conversations easily in real life. We can have the students repeat the lines with sopt-checks to make sure they have picked up the correct intonation patterns and then ask them to practice the dialog at home, using the audio CD/tape. Meanwhile, we can have them make their own conversations using the new words in vocab and practice in pairs.
