This is the second teaching period of this unit. The teacher can first check students’ homework and offer chances for students to review what they learned during the first period.
The emphasis of this period will be placed on the important new words, expressions and sentence patterns in the parts Warming Up, Pre-reading, Reading and Comprehending. In order to make students understand these important points thoroughly, we can first get students to understand their meanings in the context, then give some explanations about them, later offer some practices to make students master their usages.
