1、 Practice verb tenses with a chart. Write “yesterday”，“today”，“tomorrow” across the top of the blackboard. Ask the students to call out words from the lesson in the student book. Write these under “yesterday”. Then write “buy”，“think”, “teach”, “go”, “see” and “eat” under “today”. Ask the students to call out the corresponding words in the lesson for me to write under “yesterday”. Then ask for volunteers to complete the chart.
2、 Divide the class into pairs. Each student draws a picture of something that happened during Li Ming’s visit to Canada. They label as much of their pictures as they can in English. They then take turns describing their pictures to their partners.
