Period 2 Learning about language: Important language points
整体设计
教材分析
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 practice to make students master their usages. Some new words and expressions, such as surround, measure, confirm, impress, rather than, manage to do, and so on are very useful and important. So are the sentence patterns “The thought that they could cross the whole continent was exciting. ” and “It is so wet there that the trees are extremely tall, some measuring over 90 meters. ” We ought to pay more attention to them and design special exercises.
At the end of the class, the teacher can make students do more exercises for consolidation. In doing so, they can learn, grasp and use these important language points well.
