This is the fourth teaching period of this unit. As usual, the teacher will first get students to review what they learned in the last period, and then lead in the new lesson.
We will mainly deal with listening and speaking in this period. At the beginning, students listen to a conversation among young people. Carla and Hari are students in Trinidad. Their Chinese friends Li Mei and Wu Ping, are visiting for the Carnival holiday in February.
