The most important step of this lesson is while-reading, and I will design it in the following aspects. First of all, I will ask students to read the passage quickly for the first time and find out the main idea of it and arrange the pictures on the textbook in an correct order. It can help students have an basic understanding about this passage. After that, I will ask students to read the passage again carefully and match the growing process with the dates on the blackboard. This activity can help student know the detailed information of the kittens’ growing. Finally, I will ask them to read the whole passage which can improve their pronunciation.
