Teaching Reflectin
This is the secnd perid f the unit. In the unit we talk abut pllutin and envirnmental prtectin. S it is imprtant t get the students t learn wrds and phrases abut the tpics in this unit. We will review sme structures and tenses and get the students t practice them in listening and speaking. They are “shuld＋d; used t＋d; have / has＋dne; be＋dne; be＋ding”. The tpic is an imprtant cntent in ur life and students shuld learn t use the wrds and structures t talk abut and write abut it. S much practice shuld be dne in the perid and in later perids.
