This is the third teaching period of this unit. The teacher should first check the students’ homework and offer chances for the students to review what they learned in the second period.

The emphasis in this period will be put on the important new words, expressions and sentence patterns. In order to make the students understand these important points tho-roughly, the teacher can first get the students to understand their meanings in the context, then give some explanations about them, and later offer some practices to let the students know their usages. At last make the students do more exercises for consolidation.
